Answers

Answer 1

SOLUTION

The duration for watering the whole flower is

[tex]\begin{gathered} \text{ finishing time- starting time } \\ 13\colon25-11\colon36 \\ \end{gathered}[/tex]

Which is

[tex]1\text{hours 49minutes or 109 minutes }[/tex]

This means it takes 109minutes for watering the whole flowers.

The time taken for 4/7 of the flowers is

[tex]\begin{gathered} \frac{4}{7}0f\text{ 109} \\ \\ \frac{4}{7}\times109=\frac{436}{7}=62.29 \\ \\ \end{gathered}[/tex]

Then it takes 62minutes 29seconds to wet 4/7 of the flowers

[tex]\begin{gathered} 62\text{minutes 29 seconds will be } \\ 1\text{hours 0.5minutes } \end{gathered}[/tex]

The time they will finish watering 4/7 of the flowers will be

[tex]\begin{gathered} \text{starting time +Duration for 4/7 of the flowers } \\ 11\colon36+1;05 \\ 12\colon41 \end{gathered}[/tex]

Two systems of equations are given below.For each system, choose the best description of its solution.If applicable, give the solution.System AThe system has no solution.The system has a unique solution:3x + 5y = 112x + 5y=4(x, y) = (1,5The system has infinitely many solutions.System BThe system has no solution.The system has a unique solution:y = 3x + 7y = 3x + 4(x, y) = (2, 2)The system has infinitely many solutions.

Answers

We are given the following system of equations:

[tex]\begin{gathered} 3x+5y=11,(1) \\ 2x+5y=4,(2) \end{gathered}[/tex]

We can solve this system of equations using the method of elimination. To do that we will multiply equation (2) by -1:

[tex]-2x-5y=-4,(3)[/tex]

Now we add equations (1) and (3):

[tex]3x+5y-2x-5y=11-4[/tex]

Adding like terms:

[tex]x=7[/tex]

Now we replace the value of "x" is equation (1):

[tex]\begin{gathered} 3(7)+5y=11 \\ 21+5y=11 \end{gathered}[/tex]

Now we subtract 21 to both sides:

[tex]\begin{gathered} 5y=11-21 \\ 5y=-10 \end{gathered}[/tex]

Dividing both sides by 5:

[tex]\begin{gathered} y=-\frac{10}{5} \\ y=-2 \end{gathered}[/tex]

Therefore, the solution of the system is:

[tex](x,y)=(7,-2)[/tex]

For the second system of equations:

[tex]\begin{gathered} y=3x+7,(1) \\ y=3x+4,(2) \end{gathered}[/tex]

These equations represent two lines with the same slope, and therefore, parallel lines. Since they are parallel lines this means that the system has no solutions.

Write a equation of a line in slope intercept form that is perpendicular to the line y= [tex] \frac{1}{4} x[/tex]and crosses through the point (-3, -2)

Answers

[tex]\begin{gathered} \text{The equation of the line is;} \\ \\ y\text{ = -4x - 14} \end{gathered}[/tex]

Here, we want to write the equation of a line that passes through the given point and is perpendicular to the given line

When two lines are perpendicular to each other, what this mean is that the product of their slopes are equal to -1

Generally, the equation of a straight line can be written in the form;

[tex]y\text{ = mx + b}[/tex]

where m is the slope of the line and b is the y-intercept of the given line

Now from the given equation, we can see that the coefficient of x is 1/4. What this mean is that the slope of the line is 1/4 (the line's y-intercept is zero)

We can then proceed from here to get the slope of the second line

Mathematically, since the two lines are perpendicular;

[tex]m_{1\text{ }\times\text{ }}m_2\text{ = -1}[/tex]

Thus;

[tex]\begin{gathered} \frac{1}{4}\text{ }\times m_2\text{ = -1 } \\ \\ m_2\text{ = -1 }\times\text{ 4 = -4} \end{gathered}[/tex]

This shows that the slope of the second line is -4

We can write the equation of the second line as;

[tex]y\text{ = -4x + c}[/tex]

To completely write the equation of the second line, we need to get the value of c

To do this, we substitute the coordinates of the point that lies on the line

The point we are given is (-3,-2)

So in this case, we substitute the value x = -3 and y = -2

Thus, we have;

-2 = -4(-3) + c

-2 = 12 + c

c = -2 -12

c = -14

I have a triangle and diamond on an equation which is =1.05so I am asking am I suppose to divide by 2 to get the answer?

Answers

Let,

T = Triangle

S = Semi Circle

R = Star

D = Diamond

Given:

a.) 4 Triangles = 2 Semi Circle + 2 Star → 4T = 2S + 2R

b.) 1 Triangle + 1 Diamond = 1.05 → 1T + 1D = 1.05

c.) 1 Star + 1 Semi Circle = 0.525 → 1R + 1S = 0.525

d.) Diamond = ?

For us to be able to determine the value of the diamond, we must be able to determine the value of the Triangle.

For us to get it, we will be using first the equation at a and c.

4T = 2S + 2R

1R + 1S = 0.525

We get,

2S + 2R = 2(1S + 1R)

2S + 2R = 2(0.525)

2S + 2R = 1.05

Let's now get the value of the triangle,

4T = 2S + 2R

4T = 1.05

T = 1.05/4

T = 0.2625 (Value per triangle)

Let's now determine the value of the DIAMOND.

1 Triangle + 1 Diamond = 1.05 → 1T + 1D = 1.05

1T + 1D = 1.05

1(0.2625) + 1D = 1.05

0.2625 + 1D = 1.05

1D = 1.05 - 0.2625

1D = D = 0.7875

ANSWER: The value of the diamond is 0.7875

Answers

answer:

y = -2/3x -4/3

step-by-step explanation:

you start with 6x-9y = 12. you need to get y alone and on its own side of the equal sign.

starting easy, all coefficients (6, -9, and 12) have a GCF of 3. so, let's divide all sides by 3.

you are left with 2x-3y=4. now, we need to get -3y on its own side of the equal sign before we can get rid of its coefficient (-3). also, when identifying the coefficient of x, y, or any variable, include the + or - sign. you just don't need to write +, but you have to write -.

2x-3y=4 means we subtract 2x from both signs because it is positive. we now have

-3y = 2x + 4. let's divide by -3 to get y on it's own

y = -2/3x -4/3

Explanation:

The median of a data set is the value that lies in the middle of the ordered data set.

In this case, we have:

19,3,7,1,11,19,2,3,17,4,14,12

We need to order the list in ascending order:

1, 2, 3, 3, 4, 7, 11, 12, 14, 17, 19, 19

There are 12 values, since is an even number, the median is the average of the pair in the middle.

In this case, the pair in the middle is 7 and 11. The average is:

[tex]\frac{7+11}{2}=\frac{18}{2}=9[/tex]

Thus, the median is 9

The count in a bacteria culture was 800 after 15 minutes and 1000 after 30 minutes. Assuming the count grows exponentiallyA)What was the initial size of the culture? B)Find the doubling period. C)Find the population after 60 minutes. D)When will the population reach 13000.

Answers

Answer:

A) The initial size o the culture is 640

B) The doubling period is 47 minutes

C) The population after 60 minutes is 1563

D) The population will reach 13000 after 3 hours 22 minutes

Explanation:

The form of an exponential grow model is:

[tex]S=Pb^t[/tex]

Where:

S is the population after t hours

P is the initial population

b is the base of the exponent

t is the time, in hours

We know that after 15 minutes, the population was 800. 15 minutes is a quarter of an hour. Thus, t = 1/4, S = 800:

[tex]800=Pb^{\frac{1}{4}}[/tex]

Also, we know that after 30 minutes, the population was 1000. Thus, t = 1/2, S = 1000

[tex]1000=Pb^{\frac{1}{2}}[/tex]

Then, we have a system of equations:

[tex]\begin{cases}800=Pb^{\frac{1}{4}}{} \\ 1000=Pb^{\frac{1}{2}}{}\end{cases}[/tex]

We can solve the first equation for P:

[tex]\begin{gathered} 800=Pb^{\frac{1}{4}} \\ P=\frac{800}{b^{\frac{1}{4}}} \end{gathered}[/tex]

And substitute in the other equation:

[tex]1000=\frac{800}{b^{\frac{1}{4}}}b^{\frac{1}{2}}[/tex]

And solve:

[tex]\frac{1000}{800}=\frac{b^{\frac{1}{2}}}{b^{\frac{1}{4}}}[/tex][tex]\begin{gathered} \frac{5}{4}=b^{\frac{1}{2}-\frac{1}{4}} \\ . \\ \frac{5}{4}=b^{\frac{1}{4}} \end{gathered}[/tex][tex]\begin{gathered} b=(\frac{5}{4})^4 \\ . \\ b=\frac{625}{256} \end{gathered}[/tex]

Now, we can find the initial population P:

[tex]P=\frac{800}{(\frac{625}{256})^4}=\frac{800}{\frac{5}{4}}=\frac{800\cdot4}{5}=640[/tex]

The initial population is 640

To find the doubling period, we want that the population equal to twice the initial population:

[tex]S=2P[/tex]

Then, since we know the equation, we can write:

[tex]2P=P(\frac{625}{256})^t[/tex]

Then:

[tex]\begin{gathered} \frac{2P}{P}=(\frac{625}{256})^t \\ . \\ 2=(\frac{625}{256})^t \\ \ln(2)=t\ln(\frac{625}{256}) \\ . \\ \frac{\ln(2)}{\ln(\frac{625}{256})}=t \\ . \\ t\approx0.7765 \end{gathered}[/tex]

If an hour is 60 minutes:

[tex]60\cdot0.7765=46.59\approx47\text{ }minutes[/tex]

To find the population after 60 minutes, we use t = 1 hour and we want to find S:

[tex]\begin{gathered} S=640(\frac{625}{256})^1 \\ . \\ S=640\cdot\frac{625}{256}=1562.5 \end{gathered}[/tex]

To find when the population is 13000, then we use S = 13000 and solve for t:

[tex]\begin{gathered} 13000=640(\frac{625}{256})^t \\ . \\ \frac{13000}{640}=(\frac{625}{256})^t \\ . \\ \frac{325}{16}=(\frac{625}{256})^t \\ . \\ \ln(\frac{325}{16})=t\ln(\frac{625}{256})^ \\ . \\ t=\frac{\ln(\frac{325}{16})}{\ln(\frac{625}{256})}\approx3.373 \\ \\ \end{gathered}[/tex]

We have 3 full hours and 0.373. Since one hour is 60 minutes:

[tex]60\cdot0.373\approx22[/tex]

The population reach 13000 after 3 hours 22 minutes

Now, to compute the area of the given section we will use the following diagram.

To compute the area of each triangle we will use the following formula for the area of a triangle:

[tex]\begin{gathered} A=\frac{bh}{2}, \\ \text{where b is the base of the triangle and h is its height.} \end{gathered}[/tex]

And to compute the area of the rectangle we will use the following formula:

[tex]\begin{gathered} A=bh, \\ \text{where b is the base of the rectangle and h is its height.} \end{gathered}[/tex]

Therefore the area of triangle A is:

108A) 54B) 60C) 68D) 72BCNote: Figure not drawn to scale.In the figure above, lines and m are paralleland BD bisects ZABC. What is the value of x?

Answers

Given the shown figure:

lines l and m are parallel

So, m∠A = m∠ABC

Because the alternative angles are congruent

So, m∠ABC = 108°

And BD bisects the m∠ABC

So, m∠CBD = 1/2 * m∠ABC = 1/2 * 108 = 54°

As the lines l and m are parallel

So, m∠CBD = m∠D = x

So, the answer will be x = 54

The answer will be A) 54

The ratio of the quantities of sugar and flour needed to bake a cake is 2:5. What is the quantity of sugar needed for a cake, if 750 grams of flour are used to bake it?

Answers

The quantity of sugar needed for a cake, if 750 grams of flour are used to bake it is 300 grams.

What is ratio?

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them.

In this case, the ratio of the quantities of sugar and flour needed to bake a cake is 2:5.

The quantity of sugar needed is illustrated by x.

This will be:

2/5 = x/750

Cross multiply

5x = 2 × 750

5x = 1500

Divide

x = 1500/5

x = 300

The sugar needed is 300 grams.

About 1% of the population has a particular genetic mutation. 100 people are randomly selected.Find the standard deviation for the number of people with the genetic mutation in such groups of 100. (Remeber that standard deviation should be rounded to one more decimal place than the raw data, in this case 1 decimal place is necessary.)

Answers

ANSWER:

1.0

STEP-BY-STEP EXPLANATION:

Given:

p = 1% = 0.01

q = 1 - p = 1 - 0.01 = 0.99

n = 100

The standard deviation is calculated using the following formula:

[tex]\begin{gathered} \sigma=\sqrt{n\cdot p\cdot q} \\ \\ \text{ We replace each value and obtain the standard deviation:} \\ \\ \sigma=\sqrt{100\cdot0.01\cdot0.99} \\ \\ \sigma=\sqrt{0.99} \\ \\ \sigma=0.99498 \\ \\ \sigma=0.995\rightarrow1\text{ decimal place}\rightarrow1.0 \end{gathered}[/tex]

Therefore, the standard deviation is equal to 1.0
