Answer:
50
Step-by-step explanation:
Set up the equation
12/x = 240/1000
cross multiply
1000(12) = 240(x)
12000 = 240x
divide both sides by 240
x = 50

Step-by-step explanation:
Answer:
The length of the third piece of the ramp is;
D. 9.24 feet
Step-by-step explanation:
The given parameters are;
The height of the ramp = 8 feet
The angle between the piece that forms height and the base = 90°
The angle formed by the third piece connecting the height of the ramp to the furthest point and the 8 foot piece = 30°
Let 'y' represent the 8-foot piece forming the height, and let 'r' represent the third piece, by trigonometric ratio, we have;

Therefore, we get;


The length of the third piece, r ≈ 9.24 feet
Answer:
A) sarah = $ 937.33 ; claire = $928.00
Step-by-step explanation:
<h2><u>Sarah - Compound interest </u></h2>
compund interest formula :
A = P ( 1 + r/100) ^ n
A is the amount invested
P is the principle
r is the rate of interest
n is the number of years
A = 800 * ( 1 + 2 /100) ^8
=937.33
Sarah has $ 937.33
<h2><u>Claire - Simple interest </u></h2>
simple interest formula :
= PRT / 100
P is the principle
R is the rate
T is the number of years
= 800*2*8 /100
=128
128 + 800 = 928
claire has $ 928
