Answer:
Step-by-step explanation:
P = $ 500 ;r =8% ; n= 8
A = P* (1+r/100)^n
A= 500 * ( 1 + 8/100)⁸
= 500 * ( 1 + 0.08)⁸ = 500 * 1.08⁸
=500*1.85
= $ 925.45
Answer:
2
Step-by-step explanation:
Subtract 1 from 7, and then divide 6 by 3.
Hey there!
When dealing with percent word problems, the word "is" means equals. Let's see what we can do with your problem.
If the small school had 60% boys, it will have 40% girls. The number of boys <em>is</em> 48, which should equal 60% of the total, which we can model below, with t representing the total number of kids. In decimal form, 60% is 0.6.
0.6t=48
We divide both sides by 0.6.
t=80
Therefore, there are 80 total kids at the school.
We can also check our answer below.
BOYS: 0.6(80)= 48
GIRLS: 0.4(80)=32
48+32=80
I hope that this helps!
2x-y=60/100* 5y
2x-y= 6*5y/10
2x-y=3y
2x=3y+y
2x=4y | :2
x=2y | :x
1=2y/x :2
⇒ y/x= 1/2
Answer:
65°
Step-by-step explanation:
<3 + <6 = 180 because they are same side interior angles
115 + <6 = 180
Subtract 115 from each side
115-115 +<6 = 180 -115
<6 = 65
