Sam cleaned 1/3 of his house in 50 minutes. How many hours will it take him to clean his entire house?
please give me the correct answer and full explanation
This is equivalent to equivalent to 2 hours, 30 minutes.
======================================================
Work Shown:
1/3 of the house = 50 minutes
3*(1/3 of the house) = 3*(50 minutes)
3/3 of the house = 150 minutes
1 house = 150 minutes
-----------
Sam will need 150 minutes to clean the whole house
Divide this over 60 to convert to hours
150 minutes = (150/60) hours
150 minutes = 2.5 hours which is the final answer
-----------
Or you could say the following
150 minutes = 120 min + 30 min
150 minutes = (120/60) hr + 30 min
150 minutes = 2 hr + 30 min
This shows that 2.5 hours is equivalent to 2 hours, 30 minutes.

can someone please help me with the 2 questions below. (they go together)
Answer:
r=√(A/π)
r=2.8
Step-by-step explanation:
We want to get (r) alone on one side
A=πr^2
divide each side by π
A/π=r^2
square root each side
√(A/π)=r
r=√(A/π) is the answer to your first question.
now we are given A
r=√((25)/3.14)
put the left side into a calculator
r=2.8216632
round to nearest tenth of a centimeter
r=2.8

2x+3y=13
4x-y=-2
Thanks
Answer:
2x+3y=13 ------(1)
4x-y=-2 -----(2)
Multiply (1) by 2,
=> 4x + 6y = 26. ---(3)
Subtract (2) from (3),
4x - 4x + 6y + y= 26 + 2
7y = 28
y = 4
x = (13-3(4))/2
x = 1/2.

Friend: y=8+5x
14+3x=8+5x
14=8+2x
6=2x
3=x
y=14+3(3)=23

Write the ratio 2/3.5
in simplest form.
Answer:
The given ratio, in simplest form, is 4/7.
Step-by-step explanation:
Rewrite 2/3.5 as 4/7 by multiplying both the 2 and the 3.5 by 2. This eliminates the decimal fraction.
The given ratio, in simplest form, is 4/7.
The given 2/3.5 in simplest ratio form is 4 : 7.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, A ratio 2/3.5 this can be written as 2 : 3.5 as we know a/b can be written as a : b.
Now, Multiplying 10 to remove the fraction,
2×10 : 3.5×10.
20 : 35.
4 : 7.

Tilly and GiGi require different brands of dog food. Tilly’s food costs $65.00 and GiGi’s food costs $35.00. Tilly’s food comes in a 30lb bag and GiGi’s comes in a 20lb bag. Tilly and GiGi’s owners stocked up on bags of food for the dogs by spending $370 for a total of 170lbs of dog food.
Write a system of equations that best models t, the number of bags of Tilly’s dog food, and g, the number of bags of GiGi’s dog food.
65t+35g=370
30t+20g=170
