If 3 1/2 pounds of bananas cost $.98, how much would one pound cost?

Answers

Answer 1
Answer: The way you would find how much one pound costs is divide .98 by 3 1/2. 3 1/2 in decimal form is 3.5 so .98 ÷ 3.5 = .28

So one pound of bananas would cost $0.28

Hope that helped!

What is 0.063 in scientific notation?

Answers

Remember that you must change this number so that it is between 1 and 10, and then multiply it by a power of 10.

So first, you have to move the decimal point over 2 places to the right.

Since you are moving to the right, the exponent on ten will be negative; since you moved 2 decimal places, you know the exponent will be -2.

The answer is 6.3 x 10^-2.

Hope this helps!
To put a number into scientific notation, we multiply or divide the number by 10 over and over until we have a number between 1 and 10.  But we can't just change a number so we have to account for what we did by describing how many times we multiplied or divided with exponents.

Each time we multiply by 10 the decimal moves 1 place to the right.  Each time we divide by 10 the decimal moves 1 place to the left.  The exponent we use will describe the number of times we moved the decimal to the right or left.  The exponent will be positive or negative to describe the direction we need to move the decimal to represent our original number.

I know... that sounds confusing, but it's really easy!  Let's do yours...

0.063

Now we need to move the decimal to get a number between 1 and 10.  So we move the decimal 2 places to the right to get 6.3

Now we have to describe how to get to the original number with the exponents.  We moved the decimal 2 places right so to get our number back we would have to move it back 2 places to the left so  negative exponent 2...  Here's how we represent it..

6.3 x 10^-2

So what that says is if we take 6.3 and divide it by 10 twice we will get our original number.

Let's do another...

0.000000000623

We move the decimal 10 places to the right so our scientific notation is

6.23 x 10^-10

What about very large numbers...

650,000,000,000 = 6.5 x 10^11

(In that one the exponent is positive because we have to multiply to get back to the original number)

A cereal company packs its oatmeal into cylindrical containers. The height of each container is 10 inches, and the radius of the bottom is 4 inches. What is the volume of the container to the nearest cubic inch?

The volume of the container is approximately 502 cubic inches.

What is a cylinder?

A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.

Given information:

A cereal company packs its oatmeal into cylindrical containers.

The height of each container is 10 inches, and the radius of the bottom is 4 inches

The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base and h is the height.

In this case, the radius is 4 inches and the height is 10 inches. Substituting these values into the formula, we get:

V = π(4²)(10)

V = 160π

Using a calculator, we can approximate π to be 3.14 and calculate the volume:

V ≈ 160(3.14)

V ≈ 502.4

Therefore, the volume of the container is approximately 502 cubic inches.

#SPJ2

Volume = Area of the base x height
To find the area of the base (the circle on the top or bottom), we use the formula
A = π r²
A= π 4²  = π 16
Now multiply by 10 (the height) and we get  10 x π x 16 or 160π in³

Some teachers allow you to leave the answer in π units. Other want you to  multiply it by 3.14

So the answer is 160π in ³  or 502.4 in ³

Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 18 feet by 18 feet by 6 inches for a patio if the concrete costs $42.00 per cubic yard? 252.00
756.00
1,134,00
6,804,00

Answers

18 feet = 18/3 yard = 6 yard
6 inches = 1/2 feet = 1/6 yard

Volumen = (6yar)(6yard)(1/6yard) = 6 cubic yard

Cost = 6 cubic yard * $42.00 / cubic yard = $ 252.00

Answer: the first option, 252.00
Volume of slab = 18 feet * 18 feet * 6 inches = 6 yards * 6 yards *  1/6 yards = 6 cubic yards.
Cost of 1 cubic yard = $42
Cost of 6 cubic yards = $42 * 6 = $252
