$5000 is the correct answer.
The formula for simple interest is I=prt. Anson gets 10% interest; 10% = 10/100 = 0.1. This gives us
I=p(0.1)(1) = 0.1p.
Jenny borrows 1000 more than Anson, so her principal is p+1000. Her rate is 8%; 8%=8/100 = 0.08. She invests it for half of a year, or 0.5. Together this gives us:
I=(p+1000)(0.08)(0.5)
= (p+1000)(0.04)
= p*0.04 + 1000*0.04
= 0.04p + 40
Together they earned 740:
0.1p+0.04p+40 = 740
Combine like terms:
0.14p+40 = 740
Subtract 40 from both sides:
0.14p+40-40 = 740-40
0.14p = 700
Divide both sides by 0.14:
0.14p/0.14 = 700/0.14
p = 5000
Answer
23.70
Proof
3Q+5+2-8-5=65 ~ Simplify
3Q-6=65 ~Cancel out the six
+6 +6 ~Add 6 to both sides since it is a 3Q=71 negative.
/3 /3 ~Cancel out the three.
Answer ~Divide both sides by 3
Q=23.66
Rounded Up
Q=23.70
Answer:
D)
Step-by-step explanation:
Coefficient of x is -3/2 and so multiply the whole equation by 2
3x + 2y = -8
The number of feet of fencing that is needed to go around the pool path is D. 201 ft.
<h3>
How to calculate the number of feet?</h3>
We have a pool with a radius of 28 feet. The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= (28 + 4) feet
= 32 feet
The circumference of the outer edge of the pool path would be equal to the perimeter.
p = 2 * pi * r
p = 2 * 3.14 * 32
p = 200.96 feet
p = 201 feet

The answers are A and E because .026 x 100 = 2.6 and 2.60 / 100 = .026
