Answer:

Step-by-step explanation:

Southville is due south of Portland and Westfield is due west of Portland. So the three cities form a right-angled triangle on a map.

The distance between Southville and Westfield = sqrt( 57^2 + 76^2)

= 95 miles

A squared + B squared = C squared

57 squared + 76 squared =

(Distance between Southville and Westfield) squared

square root of (3249 + 5776) = Distance between Southville and Westfield

square root of 9025 = Distance between Southville and Westfield

Distance between Southville and Westfield = 95 miles

Hope this helps! God bless :-)

It costs $50.00 to deliver 6 floral arrangements. It costs $80.00 to deliver 12 floral arrangements. What is the constant rate o

german

The constant rate for 1 floral arrangement is $5.00 and inital value is $20.00

Equation: f(z)=20+5z

Step-by-step explanation:

Given,

Delivery cost of 6 floral arrangements = $50.00

Delivery cost of 12 floral arrangements = $80.00

Let,

x be the constant rate for each floral arrangement.

y be the initial value.

According to given statement;

6x+y=50.00 Eqn 1

12x+y=80.00 Eqn 2

Subtracting Eqn 2 from Eqn 1

$(12x+y)-(6x+y)=80.00-50.00\\12x+y-6x-y=30.00\\6x=30.00$

Dividing both sides by 6

$\frac{6x}{6}=\frac{30.00}{6}\\x=5.00$

Putting in Eqn 1;

$6(5.00)+y=50.00\\30.00+y=50.00\\y=50.00-30.00\\y=20.00$

The constant rate for 1 floral arrangement is $5.00 and inital value is $20.00

Equation for the function;

Let z be the number of floral arrangements.

f(z) = initial fee + 5*Number of floral arrangements

f(z) = 20+5z

The question is Fiona's swimming pool is a right rectangular prism. It holds 137 1/2 cubic feet of water. The length of the pool

cricket20 [7]

Answer:

The width is 4 feet

Step-by-step explanation:

Yes, I might be able to answer it! Hello there!

In this question, we are asked to calculate the height of a pool which has a shape of right rectangular prism.

The key to solving this problem is simply by knowing the formula for the volume of a right rectangular prism.

Mathematically the volume V is w * h * l where w , h and l are the width, height and length respectively.

Now let’s input these values and get what the height of the pool is.

It would be easier if you had the measurements are in decimals;

137 1/2 becomes 137.5

6 1/4 becomes 6.25

5 1/2 becomes 5.5

kindly note the fraction 1/2 is 0.5 in decimals while the fraction 1/4 is 0.25 in decimals

So now let’s compute the height;

137.5 = w * 6.25 * 5.5

w = 137.5/(6.25 * 5.5)

w = 137.5/(34.375)

w = 4 feet
