Answer 1

Answer:

the first one should be 5.28x10^-2 and the second one should be 3.2x10^6

Step-by-step explanation:

because with 0.0528 you move the decimal right twice. which makes it negative.

with 3,200,000 you assume that the decimal is at the end and move it between the three and the two. making it have 6 moves. since it moves left its positive

Answer 2

Answer:

0.0528=5.28*10^-2

Step-by-step explanation:

Scientific notation is a simpler way to write very large or very small numbers. In this case, you want to write a small number in simpler form. To write in scientific notation, the number being multiplied always has to be between 1 and 10. Here, it is 5.28, so we aren't breaking the rule. You can see that we moved the decimal two places to the right, which is going to make the exponent negative (the opposite applies for larger numbers). To convert to scientific notation, move the decimal place to the right or left until you get a number between 1 and 10. Then, if you moved to the right, multiply the number that is between 1 and 10 by 10 the the negative [# of spaces that you moved the decimal] power. If you moved it left, do the same but a positive exponent. To convert from scientific notation, write the number that is being multipied by 10 on a sheet of paper. if the exponent is negative, you'll have to move the decimal left for every number that the exponent is. For example, if the exponent was -5, you would move the decimal to the left 5 times. If it was just 5, you would move the decimal to the right 5 times. Then, there's your number.

Cheerios $3.89 for 17 oz. $ [ Select ] per ounce VS. Option 2: Apple Jacks $2.89 for 13 oz. $ [ Select ] per ounce Which is the better deal?

Answers

I think your best bet is to go with Apple Jacks.

The better deal is Cheerios because
If you take the ounces for each (17 & 13)
And divide them by the price ($3.89 & 2.89)
It would give you the amount 1 ounce would be (aka the constant) and the constant for Cheerios is 4.3701 where as the constant for Apple Jacks is 4.4981. Therefore, Cheerios is the better deal cause you get more.

A store sells grape jelly in 16-ounces jars for $ 4.68. How much is the jelly per ounce?

Answers

Answer:

.29 per ounce

Step-by-step explanation:

divided the cost by the amount

4.68/16

Answer:

$0.29 per ounce of jelly

Step-by-step explanation:

Because you have to divide $4.68 by 16.

Which is $0.2925.

And to round $0.2925 you have to keep it the same and not round up because 2 is not big enough to round this number.

So the answer is $0.29.

how much shaved ice was used to make the lemon ice cone, assuming the cone is completely full?

(A) The amount of shaved ice inside the cone is
______ π cubic inches.

(B) The amount of shaved ice on top of the cone is
______ π cubic inches.

(C) The total amount of shaved ice used to make the cone is
______ π cubic inches.

Answers

Answer:

(A) The amount of shaved ice inside the cone is 2.625π cubic inches.

(B) The amount of shaved ice on top of the cone is 2.25π cubic inches

Step-by-step explanation: I got the answers wrong on Time4Learning, Then it told me the correct answers. I hope this can help someone else get it correct!

The amount of shaved ice inside the cone and on top of the cone is 2.625 π and 2.25 π cubic inches. Then The total amount of shaved ice used to make the cone is 4.875 π cubic inches.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Ice cream is the combination of the cone and hemisphere.

Height of cone (h) = 3.5 in

Radius of come and hemisphere (r) = 1.5 in

(A) The amount of shaved ice inside the cone will be

[tex]\rm Volume\ of \ cone = \dfrac{1}{3} \pi r^2 h \\\\Volume\ of \ cone = \dfrac{1}{3} \pi 1.5^2 * 3.5\\\\Volume\ of \ cone = 2.625 \ \pi[/tex]

The amount of shaved ice inside the cone is 2.625 π cubic inches.

(B) The amount of shaved ice on top of the cone will be

[tex]\rm Volume\ of \ hemisphere= \dfrac{2}{3} \pi r^3 \\\\Volume\ of \ hemisphere= \dfrac{2}{3} \pi 1.5^3\\\\Volume\ of \ hemisphere= 2.25 \ \pi[/tex]

The amount of shaved ice on top of the cone is 2.25 π cubic inches.

[tex]\rm Total\ amount = Volume\ of \ hemisphere + Volume\ of \ cone\\\\Total\ amount = 2.625+ 2.25 \\\\Total\ amount = 4.875[/tex]

The total amount of shaved ice used to make the cone is 4.875 π cubic inches.

Write an expression that is equivalent to three over four (5z+ 16).

15 over four z + 16
15 over four z + 12
three over four z + 16
three over four z + 12

Answers

Your answer is 15 over four z + 12. Using the distributive property, 3/4 • 5z equals 15/4z, which can't be simplified. Then 3/4 of 16 is 12. If you divide 16 by 4 (the denominator) and then multiply by 3 (the numerator) that yields your answer.
