The price of pants is bigger than the price of a shirt by 4$.
Mike bought 10 shirts and 5 pants.
Mike payed 20$ more for the shirts than the pants.
How much does a shirt cost?
How much do pants cost?
Answer: A shirt costs $8 and the pants cost $ 12.
Step-by-step explanation:
Let x = Cost of each shirt, y = Cost of each pant.
As per given, we have
[tex]y-x=4 \ \ \ (i)\\\\ 10x-5y = 20\ \ \ (ii)[/tex]
Multiply 5 on both sides of (i), we get
[tex]5y-5x=20 \ \ \ (iii)[/tex]
Add (ii) and (iii), we get
[tex]5x=40\\\\\Rightarrow\ x=8[/tex]
From (i), y=4+8=12
Hence, a shirt costs $8 and the pants cost $ 12.
Determine the domain and range:
Answer:
Option B is correct.
Step-by-step explanation:
Recall that the domain is the set of (unique) inputs and the range is the set of outputs (which do not have to be unique).
The set of inputs of the given relation is {-1, 9, -10, 1}, and this set is also found in Option B. The set out outputs is {7, 2, 6, -6|, which is in Option B.

Jenny collects seashells and interesting rocks. She keeps her collections in boxes shaped like rectangular prisms. Her seashell box is 5 inches tall and has a volume of 200 cubic inches. Her rock box has a volume of 280 cubic inches. The area of the base of both boxes is the same. How tall is Jenny's rock box?
Answer:
7 in
Step-by-step explanation:
volume of a rectangular prism = width x height x length
width x length = area of the base
the sea shell box
200 = width x length x 5
width x length = 200/5 = 40cm^2
rock box
280 = 40in^2 x height
height = 280/40 = 7 in
Which of the following expressions represents the distance between −3.9 and −4.7?

(Absolute value)
Answer: Choice C: none of the above
Step-by-step explanation:
The distance between two numbers would be |(number 1) - (number 2)|
--------------------------------------------------------------
Given
Number 1=-3.9
Number 2=-4.7
|(number 1) - (number 2)|

14. Rob uses free weights at the gym every 3 days and he uses the weight machines every 5 days.
Today Rob used both free weights and the weight machines. How many days will it be before he uses
both kinds of weights on the same day again?
Answer:
15 days
Step-by-step explanation:
Since he used both of the weights today, he will only do both on the day they come together.
weights: 3 days, 6 days, 9 days, 12 days, 15 days
machine: 5 days, 10 days, 15 days
Because the numbers both were the same on 15 days, then that is when he will do both of them

Kim will paint all the faces of the outside of the storage trunk when it is closed. How many square
feet will Kim paint?
Answer:
a
Step-by-step explanation:
The area of that should be painted by Kim is 55.75 ft².
What is surface area?Surface area is the amount of space covering the outside of a three-dimensional shape.
Given that a container which is in shape of rectangular prism,
We need to find the area that should be painted,
So, to find the same we will find the surface area of the prism,
SA = 2(lh + hw + wl)
l = length, w = width and h = height,
SA = 2(2.50·4 + 2.75·2.50 + 2.75·4)
= 2(10 + 6.875 + 11)
= 2 × 27.875
= 55.75
Hence the area of that should be painted by Kim is 55.75 ft²

Step-by-step explanation:
a.) 5.1 x 10^-1 can be written as 5.1 x 0.1 which equals 0.51.
b.) 1.7 x 10^4 x 8.5 x 10^-2 can be simplified either by condensing 10^4 and 10^-2 to equal 10^2, or substituting the expression into a calculator.
This should equal 1.7 x 8.5 x 10^2 or 1445.
Avery has two horses: Salt and Pepper. Every month, Salt eats 450 pounds of hay. Pepper is bigger, so he eats 550 pounds of hay each month. How many tons of hay do Salt and Pepper eat in a year?
Please help
Answer:
3.3 for pepper and 2.7 for salt which is 6 tons in total
Step-by-step explanation:
The number of tons of hay both Salt and Pepper eat in a year is 5.5 tons.
Given that, every month, Salt eats 450 pounds of hay. Pepper is bigger, so he eats 550 pounds of hay each month.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Number of pounds of hay eaten by Salt in a year
= 450 × 12
= 5400 pounds
Number of pounds of hay eaten by Pepper in a year
= 550 × 12
= 6600 pounds
Total pounds of hay eaten by both the horses = 5400+6600
= 11000 pounds
In tons = 11000/2000
= 5.5 tons
Therefore, the number of tons of hay both Salt and Pepper eat in a year is 5.5 tons.
