Answer:
There are 15 girls.
Step-by-step explanation:
The ratio is 4:3, meaning there are 7 parts.
4 parts= 20 (Boys)
This means 1 part is 20 divided by 4.
1 part= 5
3 parts= Amount of girls.
3 x 5 = 15.
There are 15 girls.
Answer:
(4.25,2)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
x = (3+5.5) /2 = 8.5/2 =4.25
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
y = ( 4+0)/2 = 4/2 =2
Answer:
12, 36, 108, 324
Step-by-step explanation:
using the recursive formula and a₁ = 4 , then
a₂ = 3a₁ = 3 × 4 = 12
a₃ = 3a₂ = 3 × 12 = 36
a₄ = 3a₃ = 3 × 36 = 108
a₅ = 3a₄ = 3 × 108 = 324
One formula for the lateral area is
A = 2(LW + H(L+W))
Filling in the given numbers, you have ...
A = 2((5.6 in)·(4.3 in) + (10 in)·(5.6 in + 4.3 in))
= 2(24.08 in² + 99 in²)
= 246.16 in²
