It would be A, but it ultimately matters what formula you are using.

V=hpr^2, r=d/2 so

V=(hpd^2)/4

h=(4V)/(pd^2) ft given that d=4 and V=527.8

What is the missing length

Zina [86]

Answer:

c = 12

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

$7.2^{2} + 9.6^{2} = c^{2}$

51.84 + 92.16 = $c^{2}$

144 = $c^{2}$

$\sqrt{144}$ = c

12 = c

hope this helps :)

On a certain hot summers day, 648 people use the public swimming pool. The daily prices are $1.50 for children and $2.25 for adu

ehidna [41]

Answer:

252 children and 395 adults

Step-by-step explanation:

Make a linear system of equations, where x represents the number of children and y represents the number of adults

x+y=648

1.50x+2.25y=1269

solve using substitution, so y=648-x,

then substitute this into the second equation, so you get 1.50x+2.25(648-x)=1269,

solve for x and you will get x equals the 252

then substitute this into the first equation, so you get 252+y=648

solve and you will get y=395

Triangle ABC is dilated to create triangle A'B'C' using point O as the center of dilation. What is the scale factor of the dilat

Fynjy0 [20]

Answer:

The scale factor is 4

Step-by-step explanation:

This question requires an attachment; I'll answer this question using the attached figure

From the attachment

Length OA = 3 units

Length OA' = 3 units + 9 units

Length OA' = 12 units

Scale Factor is calculated as follows;

$Scale\ Factor = \frac{New\ Side}{Original\ Side}$

Given that the original shape is ABC, the original side will be OA

Hence, Original Side = 3 units

New Side = OA' = 12 units

The formula becomes

$Scale\ Factor = \frac{12\ units}{3\ units}$

$Scale\ Factor = 4$

Hence, the scale factor is 4
