You are given a number line with a left endpoint R, a point in between the two endpoints (not a midpoint though) of S, and a right endpoint T. If RS = 15 and ST=9, then what is the length of RT?

You just add the lengths of RS and ST together. In your case RT= 24

An astronaut who weighs 126lb on Earth weighs only21lb on the moon. How much would a person who weights 31lb on the moon weigh on Earth?

If his weight on Earth is 126lb and only 21lb on moon, you can divide to see what is the ratio of those weights.

It means that your weight on moon will be 6 times less than on Earth.

Now we have to multiply 31lb which is weight of the person on moon by 6 to get his weight on Earth

It means that your weight on moon will be 6 times less than on Earth.

Now we have to multiply 31lb which is weight of the person on moon by 6 to get his weight on Earth

On moon our mass becomes 1/6 of actual mass so if you weigh 60 kg then your mass on moon will be 10 kg..

Similarly if your mass on moon is 31 lbs then your mass on earth will be 31*6=186 lbs.

Please mark it as best if u like it

Calcualte the area area of circle x if the diameter is 13 inches

Answer:

The area of circle x is 132.79 square feet (132.79 ft^{2} }

Step-by-step explanation:

Diameter (d) = 13 inches

Radius (r) = d/2 = (13/2) inches

Π = 22/7

Area of circle x = π(r)^2

= 22/7 x (13/2)^2

= 22/7 x 42.25

= 929.5 /7

= 132.79 square inches

Answer:

Step-by-step explanation:

Area = πr^2

r = diameter/2

r = 13/2

Area= 22/7 × (13/2)^2

= 22/7 × 169/4

Area = 132.79sqaure inch

Sibyl has seen four more films than Linda. Linda has seen twice as many films as Joel. If Sibyl has seen s films, then in terms of s, what expression can represent the number of films Joel has seen? Can you please explain it?

If Sibyl has seen 4 more films than Linda, then Linda has seen 4 less films that Sibyl. So, you can write the expression L (Linda)=S-4.

If Linda has seen twice as many films as Joel, then Joel has seen half the films that Linda has seen. So you can write this at J=1/2L.

If L=s-4, then the number of films Joel has seen can be written as 1/2(s-4).

I hope this helps!

Which shows a correct order to solve this story problem? To make a fruit smoothie, Jason needs 2.4 ounces of blackberries, 1.6 ounces of apples, and 3.4 ounces of blueberries. Jason makes 5 smoothies.

How many ounces of fruit will Jason need altogether?

A.

Step 1: Add together the weights of the three fruits.

Step 2: Multiply the sum by 5.

B.

Step 1: Add the weights of the apples and the blueberries.

Step 2: Subtract the weight of the blackberries from that sum.

Step 3: Multiply the difference by 5.

C.

Step 1: Multiply the weight of the blackberries by 5.

Step 2: Add the weights of the apples and the blueberries to that product.

Step 3: Multiply the sum by 5.

D.

Step 1: Add together the weights of the three fruits.

Step 2: Divide the sum by 5.

Put yourself in Jason's shoes and consider how you'd solve the problem.

You're given the weight of components for one smoothie. You want to make 5. Essentially, you want to add the weights together 5 times.

In 3rd grade you learned that multiplication is an easier way to do repeated addition. It makes sense to add the weights together once, then multiply the result by 5.

Selection A is appropriate.
