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
Answer:
<h2><em>
0.1π rad</em></h2>
Step-by-step explanation:
The question is incomplete. Here is the complete question.
A circle has a radius of 19m . Find the radian measure of the central angle θ that intercepts an arc of length 5m. Do not round any intermediate computations, and round your answer to the nearest tenth.
The formula for calculating the length of an arc 
θ is the central angle
r is the radius of the circle = 19m
L is the length of an arc = 5m
Substitute the given values into the formula and get the central angle θ
5 = θ/360 * 2(22/7)*19
5 = θ/2π * 119.4285714
θ/2π = 5/119.4285714
θ/2π = 0.041866
θ = 2π*0.041866
θ = 0.083732π
θ = 0.1π rad (to the nearest tenth)
<em>Hence the radian measure of the central angle that intercepts an arc of length to the nearest tenth is 0.1π rad</em>
Step-by-step explanation:
3(2x + 1) - 2(x + 5) - 5(5 - 2x) = 16
6x + 3 - 2x - 10 - 25 + 10x = 16
6x - 2x + 10x = 16 - 3 + 10 + 25
14x = 48
x = 48/14
x = 24/7

Answer:
10(1+2x)
Step-by-step explanation:
When factoring you'd take out the greatest common factor, that being ten for this problem. The greatest common factor would go on the outside of your parenthesis. What remains after dividing the greatest common factor would go on the inside of the parenthesis.
