The ratio of an object's weight on Earth to its weight on Venus is 8:7. How much would a woman who weighs 120 pounds (lbs) on Earth weigh on Venus?

Answers

She would weigh 105 pounds on Venus.
120 divided into 8 groups will equal 15.
Then subtract 15 from 120 to get 105 pounds.
Now there are 7 groups of 15 when she is on Venus and 8 groups when she is on Earth. That is where the ratio is used.

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.

Answers

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?

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.

Answers

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

Answers

Answer:The scale is 1:12, and the actual car has 16-in wheels.

Then cross-multiply

12x=16

Divide by 12

X=16/12
