Tom has a scale model of his car. The scale factor is 12. If the actual car has 16-inch wheels, what size are the wheels on the scale model?
Answer:The scale is 1:12, and the actual car has 16-in wheels.
Step-by-step explanation:
So the setup would be a proportion:
1 over 12=x over 16
Then cross-multiply
12x=16
Divide by 12
X=16/12
=4/3 or 1 and 1/3 in. wheels on the model car.

A cylindrical shaped swimming pool has a diameter of 30 feet and a water height of 4.5 feet. How many cubic feet of water is contained in the pool? Use 3.14 for pi. Round your answer to the nearest cubic foot.
Answer: A
Step-by-step explanation:
The question asks about how much space the cylinder can hold. That's how i know they are really asking for the volume of the cylinder.
Next, the volume of a cylinder is V= πr²h
R is the radius
h is the height
π= 3.14 (in this question).
We know that the diameter is 30, and that the radius is always 1/2 of the diameter. To find the radius, find 1/2 of 30. Whenever you see something of something, just turn the "of" into the multiplication sign. So just do 1/2 x 30= 15.
R= 15
H= 4.5
Pi= 3.14
Now we can plug into the formula:
Using pemdas, do exponents first. Then multiply from left to right.
V= πr²h
V= 3.14x15²x4.5
V= 3.14x225x4.5
V= 706.5x4.5
V= 3,179.25
3,179.25 rounds rounds to just 3,179 because first you round the .25 to point 3, and because 3 is under 5, it rounds down. The answer is A
Hope this helps :)) Also brainliest would be appreciated, I worked pretty hard on this :D

Please help I dont know- NO LINKS
Answer:
D
Step-by-step explanation:
yes it is.
start by multiply by 4 to get rid of the fraction on x
4 ([tex]\frac{x}{4}[/tex]) = 4(4) + 4([tex]\frac{2y}{3}[/tex])
x = 16 + 8y/3
Then by 3 to get rid of that one
3(x) = 3(16) + 3([tex]\frac{8y}{3}[/tex])
3x = 48 + 8y
Then subtract 8y from both sides to get
3x - 8y = 48

a no

In one paragraph, using your own words, describe a commercial you have seen recently and tell what the commercial was selling and what the hidden message was in it.
Answer:
A commercial I have seen recently was the Grub Hub commercial. The commercial was advertising all the types of food you could possibly buy with Grub Hub. It seems their point in this commercial was to bring consumers (people who buy the food) in and purchase their food using the Grub Hub app. Grub Hub did this by making jokes and trying to be funny with the commercial. The people in the commercial were dancing and smirking while they smacked on the "delicious" food and apparently the food was so good and tasty that even a PREGNANT woman did the splits. So basically it was not a normal commercial it was... really special. The hidden message was that it's "better" than Uber.

A math class is having a discussion on how to determine if the expressions 4 x minus x + 5 and 8 minus 3 x minus 3 are equivalent using substitution. The class has suggested four different methods.
Which describes the correct method?
*Both expressions should be evaluated with one value. If the final values of the expressions are both positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
Answer:
Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
