Astrid works in the oil and gas industry near Fort McMurray, Alberta. She earns $28.30/h and makes double time for hours worked beyond 40 each week. Calculate Astrid’s gross income for 45.25 hours worked last week.

Answers

Answer 1

We have that the first 40h are paid at $28.30 each hour, so this first 40h give $1132

[tex]28.30\cdot40=1132[/tex]

Now the other 5.25 hours that are beyond 40h the last week are paid at the double of a normal hour this means are paid at $56.60 ($28.30 x 2). Now the 5.25h give 297.15

[tex]56.60\cdot5.25=297.15[/tex]

So the total is $1429,15. The answer is $1429,15

a figure has vertices (-13,13), (26,52), (39,39) what would the new coordinates of the vertices to the nearest tenth if the image were reduced by a scale factor of 0.77 with the origin as the center of dilation

Answers

Explanation

Given that the figure has vertices (-13,13), (26,52), (39,39), to reduce the image by a scale factor of 0.77 with the origin as the center of dilation, we will multiply the x and y coordinates by the scale factors.

Tomas is leaving a tip of 18% of his original bill. If the amount of the tip is $2.34, which of the following equations can be used to find the amount of his original bill?0.18b = 2.34b - 0.18 = 2.342.34 x 0.18 = bb/2.34 = 0.18

Answers

Answer

0.18b = 2.34

Step-by-step explanation

Let's call b to the bill

The tip is 18% of the bill. To find the 18 percent of a number, we need to multiply this number by 18 and then divide by 100. In this case, the tip is:

[tex]\begin{gathered} tip=\frac{18}{100}b \\ tip=0.18b \end{gathered}[/tex]

The amount of the tip is $2.34, then:

[tex]0.18b=2.34[/tex]

Given the points A(-8,-7) and B(8,5) find the coordinates of point P on directed line segment AB that partitions AB into the ratio 3:1

Answers

Given the points A(-8,-7) and B(8,5) find the coordinates of point P on directed line segment AB that partitions AB into the ratio 3:1​

step 1

Find the distance in the x-coordinate between A and B

dABx=(8-(-8)=8+8=16 units

Find the distance in the y-coordinate between A and B

dABy=5-(-7)=5+7=12 units

step 2

we know that

point P on directed line segment AB that partitions AB into the ratio 3:1​

so

AP/AB=3/(3+1)

AP/AB=3/4

Find the x coordinate of point P

APx/ABx=3/4

substitute

APx/16=3/4

APx=16*(3/4)

APx=12 units

The x-coordinate of P is

Px=Ax+APx

where

Ax is the x-coordinate of P

Px=-8+12=4

step 3

Find the y-coordinate of P

we have that

APy/ABy=3/4

substitute

APy/12=3/4

APy=12*(3/4)

APy=9

The y coordinate of P is

Py=APy+Ay

where

Ay is the y-coordinate of P

Py=9+(-7)=2

therefore

the answer is

The coordinate of P are (4,2)

A bag of fertilizer covers 2,000 square feet of lawn. Find how many bags of fertilizer should be purchased to cover a rectangular lawn that is 29400 square feet.

Answers

Okay, here we have this:

Considering the provided information, we are going to calculate how many bags of fertilizer should be purchased to cover a rectangular lawn that is 29400 square feet, so we obtain the following:

Number of bags=Total space / Space per bag

Number of bags=29400ft² / 2000ft²

Number of bags=14.7

Number of bags≈15 bags of fertilizer.

Finally we obtain that rounded to the nearest unit, 15 bags of fertilizer are needed.

3y>2x + 122x + y ≤ -5Having trouble rewriting in form. Graphing once in form okay.

Answers

Explanation

We are given the following system of inequalities:

[tex]\begin{gathered} 3y>2x+12 \\ 2x+y\leqslant-5 \end{gathered}[/tex]

We are required to graph the given system of inequalities.

This is achieved thus:

- First, we determine two coordinates from the given inequalities:

[tex]\begin{gathered} 3y>2x+12 \\ \text{ Suppose }3y=2x+12 \\ \text{ Let x = 0} \\ 3y=12 \\ y=4 \\ Coordinate:(0,4) \\ \\ \text{Suppose }3y=2x+12 \\ \text{ Let y = 0} \\ 0=2x+12 \\ 2x=-12 \\ x=-6 \\ Coordinate:(-6,0) \end{gathered}[/tex]

- Now, we plot the points on a graph. Since the inequality is "strictly greater than", the line drawn will be broken. The graph is shown below:

- Using the second inequality, we have:

[tex]\begin{gathered} 2x+y\leqslant-5 \\ \text{ Suppose }2x+y=-5 \\ \text{ Let y = 0} \\ 2x=-5 \\ x=-2.5 \\ Coordinate:(-2.5,0) \\ \\ \text{Suppose }2x+y=-5 \\ \text{ Let x = 0} \\ y=-5 \\ Coordinate:(0,-5) \end{gathered}[/tex]

The graph becomes:

Combining both graphs, we have the solution to be:

The solution is the intersection of both graphs as indicated above.

There is a bag full of 30 different colored and/or patterned balls. How many different three ball combinations can you have if you pull three balls out of the bag?Part 2: Write down (in factorial form) the total number of possible combinations there are if you draw all the balls out of the bag one at a time.I am really stuck on part 2

Answers

Answer:

a) 4060 different combinations

b) 30!

Explanation:

Given:

Total balls of different patterns = 30

To find:

a) the different three-ball combinations one can have if 3 balls are pulled out of the bag

b) the total number of possible combinations there are if you draw all the balls out of the bag one at a time in factorial form

a) To determine the 3-ball combinations, we will apply combination as the order they are picked doesnot matter

[tex]\begin{gathered} for^^^\text{ the 3 ball comination = }^nC_r \\ where\text{ n = 30, r = 3} \\ \\ ^{30}C_3\text{ = }\frac{30!}{(30-3)!3!} \\ ^{30}C_3\text{ = }\frac{30!}{27!3!}\text{= }\frac{30\times29\times28\times27!}{27!\times3\times2\times1} \\ \\ ^{30}C_3\text{ = 4060 different combinations} \end{gathered}[/tex]

b) if you are to draw all the balls one at a time, then for the 1st it will be 30 possibilities, the next will reduce by 1 to 29 possibilities, followed by 28 possibilities, etc to the last number 1

The possible combination = 30 × 29 × 28 × 27 × 26 × 25 ......5 × 4 × 3 × 2 ×1

The above is an expansion of a number factorial. the number is 30

30! = 30 × 29 × 28 × 27 × 26 × 25 ......5 × 4 × 3 × 2 ×1

Hence, the total number of possible combinations when you draw all the balls out of the bag one at a time in factorial form is 30!

Find the formula for an exponential equation that passes through the points, (0,5) and (1,2). The exponential equation should be of the form y = ab^x

Answers

Answer:

[tex]y=5\cdot(\frac{2}{5})^x[/tex]

Explanation:

The exponential equation has the form

[tex]y=a\cdot b^x[/tex]

Since it passes through the point (0, 5). Let's replace (x, y) by (0, 5) to find the value of a

[tex]\begin{gathered} 5=a\cdot b^0 \\ 5=a\cdot1 \\ 5=a \end{gathered}[/tex]

Then, the equation is

[tex]y=5\cdot b^x[/tex]

To find the value of b, we will use the point (1, 2), so replacing x = 1 and y = 2, we get:

[tex]\begin{gathered} 2=5\cdot b^1 \\ 2=5\cdot b \\ \frac{2}{5}=\frac{5\cdot b}{5} \\ \frac{2}{5}=b \end{gathered}[/tex]

Then, the exponential equation is:

The product's factors are the number that is multiplied. Each number has a self-referential element. There are several examples of factors in everyday life, such putting candies in a box, arranging numbers in a certain pattern, giving chocolates to kids, etc. We must apply the multiplication or division method in order to determine a number's factors.The numbers that can divide a number exactly are called factors. There is therefore no residual after division. The numbers you multiply together to obtain another number are called factors. A factor is therefore another number's divisor.

The least common denominator of two fractions is not always greater than the denominators of each fraction because sometimes the least common denominator is equal to the greater denominator. For example, if we have the fractions

In this case, since you have equal denominators, the least common factor would be 5, not greater than 5.

Another example could be

In this case, the least common denominator is 9, not greater than 9.

Therefore, the least common denominator is not always greater than the denominator of the fractions.

Where P is the initial amount invested, r is the interest rate and t is the number of years and n is the number of times the interest rate is compound. Solving the equation for P, we get:

[tex]P=\frac{A}{(1+\frac{r}{n})^{nt}}[/tex]

Now, we can replace A by $12,000, r by 5% = 0.05, n by 12 because it is compounded monthly and t by 6

[tex]P=\frac{12000}{(1+\frac{0.05}{12})^{12(6)}}=8895.36[/tex]

Therefore, he should invest $8895.36 today to have enough money in 6 years.

Finally, the interest earned is calculated as

$12000 - $8895.36 = $3104.64

So, the answers are:

Invest today: $8895.36

Interest earned: $3104.64
