a tree that is 20 feet tall casts a shadow 30 feet long. a girl standing next to the tree has a shadow 9 feet long. how tall is the girl?

Answers

The shadow of the three is proportional to the shadow of the girl, then we can use a rule of three:

if x is the height of the girl: 20 is to 30 is the same as x is to 9

This can be written as:

Consider the guven system of equations,

[tex]\begin{gathered} x-y=-1 \\ 2x+y=4 \end{gathered}[/tex]

It is asked to find the correct graph which represent the solution of this system.

Logic: Find the solution and see which graph gives the same solution.

Add the equations,

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

Substitute this value in the first equation,

[tex]\begin{gathered} 1-y=-1 \\ y=1+1 \\ y=2 \end{gathered}[/tex]

Thus, the given system has a unique solution (1,2).

Now, observe that only the graph given in option (c) shows the line intersecting at point (1,2).

Therefore, option (c) is the correct choice.

if 5 pounds of apples cost 5.50,then what is the cost of 1 pound of apples

Answers

The cost of 1 pound of apple is 1.10

Here, we want to calculate the cost of 1 pound of apples given the cost of 5 pounds

From the question;

5 pounds = 5.5

1 pound = x

[tex]\begin{gathered} 5\text{ }\times\text{ x = 1 }\times\text{ 5.5} \\ \\ 5x\text{ = 5.5} \\ \\ x\text{ = }\frac{5.5}{5} \\ \\ x\text{ = 1.1} \end{gathered}[/tex]

J is the midpoint of HK, H has coordinates (5,-3), and J has coordinates (7,3). Find the coordinates of K.The coordinates of K are

Answers

Answer:

The coordinates of K is;

[tex](9,9)[/tex]

Explanation:

We want to find the coordinates of point K.

Given that J is the midpoint of HK and;

H has coordinates (5,-3)

J has coordinates (7,3).

The formula for calculating midpoint is;

[tex]\begin{gathered} x=\frac{x_1+x_2}{2} \\ y=\frac{y_1+y_2}{2} \end{gathered}[/tex]

where x1 and x2 are the x coordinates of the endpoints and y1 and y2 are the y coordinates of the endpoints.

To get the coordinates of one of the endpoints, we have;

[tex]\begin{gathered} x_2=2x-x_1 \\ y_2=2y-y_1 \end{gathered}[/tex]

substituting the given coordinates of the mid point and endpoint;

[tex]\begin{gathered} x_2=2(7)-5 \\ x_2=14-5 \\ x_2=9 \end{gathered}[/tex][tex]\begin{gathered} y_2=2(3)-(-3) \\ y_2=6+3 \\ y_2=9 \end{gathered}[/tex]

Answers

Step 1: Problem

Over the summer, Audrey had a job and earned $528. She spent $125.70 on a new bike and $85.09 for some new clothes. How much money does Audrey have left?​

Step 2: Concept

Word problem on subtraction

Step 3: Method

Audrey total earning = $528

Money spent on new bike = $125.7

Money spent on new clothes = $85.09

Money left = 528 - 125.7 - 85.09

= $317.21

Step 4: Final answer

Audrey money left = $317.21

The composition of rigid motions T(10,- 27 OT(-24,4, describes the route of a limousine in a city from its starting position. Describe the route in words. Assume that the positive y-axis points north. block(s) north, and then it drives 3 block(s) west and 4 block(s) north. First the limousine drives 2 block(s) east and (Type whole numbers.)

Answers

The problem describes two operations of translation on the car. The first operation says that the car translated "10" units on the x-coordinate and "-2" units on the y-coordinate.

When translations are performed on the "x-coordinate" if they are positive, the function is moved to the left and if they are negative the function is moved to the right. When translations are performed on the "y-coordinate" if they are positive the function is moved up and if negative, the function is moved down.

Since the first translation on the x-axis was positive, then the car moved to the left 10 units, which would be "10 blocks" on the west direction. The translation on the y-coordinate was negative, so the function moved down. The car moved "2 blocks" on the south direction.

The second translation is (-24, 4). The translation on the x-axis is negative so the car is moved 24 units to the east direction. The translation on the y-axis is positve so the car is moved 4 units on the north direction.

The final answer is:

First the limousine drives 10 blocks west and 2 blocks south and then it drives 24 blocks east and 4 blocks north.

Answers

Here, we are to calculate for the value of x.

We start by finding the Lowest common multiples of both fractions. The lowest common multiple of both fractions is 14

Now, we can multiply each of the terms in the question by 14. Thus, we have;

14(x + 3)/2 + 14(2x/7) = (7 * 14)

7(x + 3) + 2(2x) = 98

Opening the brackets, we have;

7x + 21 + 4x = 98

Collect like terms;

7x + 4x = 98 - 21

11x = 77

x = 77/11

x = 7

what does ☆ equal if the symbols below represents digits 0-9?

Answers

First, let's start from the sixth equation.

Since the parallelogram divided by the circle is equal the parallelogram, it means the circle has a value of 1.

Then, from the 7th equation, the pentagon minus the arrow is equal the pentagon, it means the arrow is equal 0.

From the 8th equation, the two curved arrows summed are equal 10, so the curved arrow is equal 5.

From the 2nd and 4th equations we can find that the triangle is equal 2.

Using the value of the pentagon from the 4th equation in the 3rd one, we have that 3 * moon is equal parallelogram, so the only option is:

moon = 3, pentagon = 6, parallelogram = 9.

From the 1st equation, the square is equal 8.

Finally, from the 5th equation, the arrow with circle is equal 7.

So we have:

pentagon = 6

parallelogram = 9

moon = 3

triangle = 2

arrow = 0

curved arrow = 5

arrow with circle = 7

circle = 1

square = 8

So the star is the missing algarism: 4

The lines represented by the equations y = 1/2x-8 and 2y+4x=10

Answers

The first equation is in slope-intercept form but the second equation is not. Therefore, our first step is to bring 2y+4x=10 into slope-intercept form.

Subtracting 4x from both sides gives

[tex]2y=10-4x[/tex]

finally, dividing both sides by 2 gives

[tex]y=-2x+5[/tex]

Now, that we have the equation in slope-intercept form, let us compare their slopes to see how they relate to each other.

The lines are perpendicular if the slope of one line is negative of the reciprocal of the other.

Now, -2 is negative of the reciprocal of 1/2. Meaning if you take the reciprocal 1/2, then multiply it by -1 you will end up with -2.

Since the slope of a negative reciprocal of each other, the lines are perpendicular.

A survey wanted to determine if there was a relationship between the number of joggers who used a local park for exercise and the temperature outside. The data in the table display their findings.Use graphing technology to create a scatter plot of the data.What is the slope of the line of best fit and what does it mean in this context? Is it realistic?

Answers

Step 1

In order to find the slope of the line of the best fit, we must graph the points given.

Step 2

From the image above we can conclude that the equation of the line is;

[tex]y=0.410045x-2.8757[/tex]

The slope is, therefore;

[tex]0.410045[/tex]

The Slope (or Gradient) we call m, represents the change in y-value per unit change in x-value. In the case of this survey, the slope represents the increase in the number of joggers per degree rise in temperature.

From the calculated slope, there are about 0.4 more joggers for every degree rise in temperature. Using whole numbers to represent this, we can multiply the slope by 5:

[tex]0.4\times5=2[/tex]

Therefore, there are 2 more joggers for every 5°F increase in temperature.

Solve for t and graph the solution.|t+ 4| < 2

Answers

The solution to the inequality is (-6, -2). The graph of the solution is attached below.

We are given an inequality. The inequality consists of a variable "t" and it also uses the modulus function. A function connects an input with an output. It is analogous to a machine with an input and an output. And the outcome is somehow connected to the input. The inequality is |t + 4| < 2. We can solve the inequality by expanding the modulus operator. The inequality becomes -2 < (t + 4) < 2. Now we will subtract 4 from all the sides in the inequality. The inequality is solved as -6 < t < -2. The interval notation for the solution is (-6, -2). The graph is attached below.
