7x1=7, then 4x1/4= 4x1=4 divided by 4= 1. Then subtract 7- 1= 6
To solve, lets find the volumes of all of the options...
V=l*w*h
A.
6*3*4=72cm³
12*2*3=72cm³
B.
2*4*9=72cm³
9*4*2=72cm³
C.
3*3*8=72cm³
2*6*8=96cm³
D.
6*3*4=72cm³
9*4*3=108cm³
We can conclude that C & D aren't the answer, since they contain prisms that don't have a volume of 72cm³.
Now lets solve for the surface area of A and B...
A.
sA=2(wh+lw+lh)=2(6*3+4*6+4*3)=2(18+24+12)=2(54)=108cm²
sA=2(wh+lw+lh)=2(12*2+3*12+3*2)=2(24+36+6)=2(56)=112cm²
B.
sA=2(wh+lw+lh)=2(2*4+9*2+9*4)=2(8+18+36)=2(62)=124cm²
sA=2(wh+lw+lh)=2(9*4+2*9+2*4)=2(36+18+8)=2(62)=124cm²
A is the only option with both similar volumes of 72cm³ and different surface areas...
Answer=A
Answer:
1
Step-by-step explanation:
Mr. Rodriguez invest *$2,000 in a savings plan the savings account pays an annual interest<span> **rate of 5.75 how much will Mr. Rodriguez earn if he leave his money in the savings plan for ***10 years?</span>
The bolded parts have a certain number of stars before it. That correlates with the below:
The equation is I = P * R * T
I = interet
* P = pay
**R = rate
***T = time (measured in years)
The pay is $2000
The rate is 5.75%
The time is 10 years.
You need to convert the rate into a decimal.
5.75% = 0.0575
2000 * 0.0575 * 10 = 1150
The answer is $1150
After 10 years, Mr. Rodriguez will have earned $1,150
Hope I helped!
