Answer:

C. 16

Step-by-step explanation:

A pole-vaulter uses a 15-foot-long pile. She grips the pole so that the segment below her left hand is twice the length of the s

Shalnov [3]

Let x + 1.5 be length of segment above left hand
Let 2x be length of segment below left hand

15 = x + 1.5 + 2x
15 = 3x + 1.5
15 - 1.5 = 3x
13.5 = 3x
13.5/3= 3x/3
4.5 = x
x = 4.5
This is the length above the left hand.

2x must be then 4.5*2 = 9 foot
This is the length below the left hand.

Checking
4.5 + 9 + 1.5 = 15 foot

Adding length below left hand & length of left hand to right hand:
9 + 1.5 = 10.5
The right hand is hence 10.5 foot far up the pole.

A school will have a fall festival if at least 40% of the 500 students plan to attend. How many students must agree to attend in

artcher [175]

Answer:

200 students must agree to attend in order for the school to have the festival.

Step-by-step explanation:

200 is 40% of 500. We can also use fractions to figure this out.

$\frac{40}{100} =\frac{x}{500}$

For 100 to become 500 it must be multiplied by 5. And whatever we do to the denominator we have to do to the numerator. So we multiply 40 × 5 = x

x = 200

$\frac{40*5}{100*5} = \frac{x}{500}$

$\frac{40}{100} =\frac{200}{500}$
