Answer:
Computer: $620
Printer: $310
Step-by-step explanation:
c + p = 930
c = 2p
c = cost of the computer
p = cost of the printer
replacing the second eq. in the first eq.
2p + p = 930
3p = 930
p = 930/3
p = 310
from the second eq.
c = 2p
c = 2*310
c = 620
Check
from the first eq.
620 + 310 = 930
Multiply (5.6 x 10") (6.1 x 10* )and write the
answer in scientific notation.
Answer:
3.416 x 10^(" + * + 1)
Step-by-step explanation:
The exponents of (5.6 x 10") (6.1 x 10* ) seem incorrect. Whatever they are, do the following:
1) multiply 5.6 times 6.1. Result = 34.16
Add the two exponents: (" + *)
The result is 34.16 x 10^(" + *)
Then move the decimal point one to the left and add 1 to the 10 exponent:
3.416 x 10^(" + * + 1)

Rectangle has length 8.1 and perimeter 28.5 find the width
Answer:
6.15
Step-by-step explanation:
perimeter of a rectangle= 2(Length + width)
perimeter=28.5
length=8.1
28.5=2(8.1+ Width)
28.5=16.2+ 2(Width)
28.5-16.2=2(Width)
12.3=2(Width)
12.3/2=Width
6.15=Width
maria's garden measures 14 feet by 16 feet and has a perimeter of 60 feet. Musharraf's garden measures 10 yards by 4 yards. What is the difference between the two perimeters?
The difference between the two perimeters is 32 yards.
Maria's garden measures 14 feet by 16 feet and has a perimeter of 60 feet.
Musharraf's garden measures 10 yards by 4 yards. The perimeter will be:
= 2(10 + 4)
= 2 × 14
= 28 yards
The difference will be:
= 60 - 28
= 32 yards.

Ethan buys a new phone. It cost 75$. He will pay for this on his 1st bill.
His phone plan charges 0.06 dollars per minute on the phone.
'He has $90 to spend on his 1st bill. How long can he be on his phone to not go over his budget?
Answer:
250 minutes
Step-by-step explanation:
90-75=15
15/0.06=250
Answer:
x = 250 minutes
Step-by-step explanation:
The equation for this problem can be set up as follows-
Y = 0.06x+75
y = total phone bill
x= number of minutes on his phone
If Ethan can spend a total of $90 maximum, then y = 90
90 = 0.06x +75 solve for X to determine how many minutes he can be on his phone to reach a $90 total.
x = 250 minutes

12² + b² = 20²
I hope this helps!
Answer:
b = 16 m
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
b² + 12² = 20²
b² + 144 = 400 ( subtract 144 from both sides )
b² = 256 ( take square root of both sides )
b = [tex]\sqrt{256}[/tex] = 16 m

Answer:
$30
Step-by-step explanation:
Over 5 years she will have been paid $30 in interest. To find the amount of interest first find the total amount the account has after 5 years. The formula for simple interest is A=P(1+rt). Where A is the total amount, P is the principal (initial amount), r is the rate in decimal form, and t is the time in years.
Plug in the values to solve, A=200(1+0.03*5). Then, simplify to get A=230. Finally, to get only the interest, I, use the formula A-P=I. So, 230-200=30. Therefore, the interest Leila earned was 30 dollars.
