a = b * c

Divide both sides by b.

a/b = c

a = b(c)

Because you are solving for c, isolate the variable. Note the equal sign, what you do to one side, you do to the other

Divide b from both sides

(a)/b = (b(c)/b

a/b = c

c = a/b is your answer

hope this helps

What are the coordinates of P' if P (-5,-4) undergoes a dilation, centered at the origin, with a scale factor of K=2?

Margaret [11]

Answer:

$P' = (-10,-8)$

Step-by-step explanation:

Given

$P = (-5,-4)$

$k =2$

Required

Determine the image P'

P' is calculated by multiplying P and k.

i.e.

$P' = P * k$

This gives:

$P' = (-5,-4) * 2$

$P' = (-5* 2,-4* 2)$

$P' = (-10,-8)$

<em>Hence, the image P' after dilating P is (-10,-8)</em>

Answer:

$16\sqrt{17}$

Step-by-step explanation:

The perimeter is two times width plus two times length:

$2\sqrt{17} + 2\cdot 7\sqrt{17} = 2\sqrt{17} + 14\sqrt{17} = 16\sqrt{17}$

There is no way to simplify further.

Trophies for Gunther's soccer team will cost $6.25 each, plus 15 cents for every word on the engraving. Which equation could be

Lynna [10]

Answer:

Step-by-step explanation:

c = $6.25 + 0.15w

$6.25 represents the fixed cost. it is the cost that does not vary with the number of words

15 cents is the variable cost. it is the cost that varies with the number of words.

to write the equation convert 15 cents to dollars by dividing by 100.

One angle of a triangle is 50 degrees greater than the smallest angle, and the third angle is 10 degrees less than twice the sm

tia_tia [17]

All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.

Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10

50+x+x+2x-10=180
4x+40=180
4x=140
x=35

Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60

60+35+85=180

A plot of land in the shape of a horizontal ellipse has a pole at each focus. the foci are 16 feet from the center. if the plot

Leviafan [203]

If a plot of land in the shape of a horizontal ellipse has a pole at each focus. the foci are 16 feet from the center. if the plot of land is 40 feet across one axis, how long is it across the other axis is: c. 24 feet.

<h3>Length across the other axis</h3>

Using Pythagoreans theorem formula

a²=b²+c²

Where:

c=16 feet

a=40/2=20 feet

Hence:

20²=b²+16²

b²=20²-16²

b²=400-256

b²=√144

b=12

2b=12×2

2b=24 feet

Therefore if the plot of land is 40 feet across one axis, how long is it across the other axis is: c. 24 feet.

The complete question is are:

A plot of land in the shape of a horizontal ellipse has a pole at each focus. The foci are 16 feet from the center. If the plot of land is 40 feet across one axis, how long is it across the other axis?

a. 34 feet

b. 46 feet

c. 24 feet

d. 30 feet
