The cow has about 200 times more mass.

The blue whale has about 500 times more mass.

There is no way to compare the masses.

Answers

Answer 1

Answer:

Answer:

The 1st answer, The blue whale has about 200 times more mass. might be correct.

Step-by-step explanation:

9 x 10 ^2= 900 kilograms

1.8 × 10 ^5= 180000 kilograms

180000 kilograms / 900 kilograms= 200 times

Multiply (-1/6) x (-1/5)
A) -1/11
B) -1/30
C) 1/30
D) 1/11

Answers

C is the answer.

Negative times a negative is a positive.

The answer would be 0.03 repeated but as a fraction it is 1/30 so it's "C". Hope I helped you out.

What is 109 percent as a decimal?

Answers

1.09

Hope I Helped You!!! :-)

Have A Good Day!!!

Answer:

1.09

Step-by-step explanation:

"Percent" means "per 100" or "over 100". To convert 109% to a decimal rewrite 109 percent in terms of per 100 or over 100.

109% = 109 over 100 or,

109%=109100109 over 100 is the same as 109 divided by 100. Completing the division we get:

109 ÷ 100 = 1.09

Therefore, we have shown that

109% = 1.09

Simplified Conversion:Remove the percent sign % and divide by 100.

109 ÷ 100 = 1.09

Shortcut Conversion:Move the decimal point 2 places to the left and remove the percent sign %

109% becomes 1.09

at a clearance sale, the price of a VCR was discounted 40%. the discounted price was 375. what was the original price?

Answers

If you would like to find the original price, you can calculate this using the following steps:

100% - 40% = 60%

x ... the original price
60% of x is 375
60% * x = 375
60/100 * x = 375
x = 375 * 100 / 60
x = 625

The original price was 625.

The volume of a prism is the product of its height and area of its base, V = Bh. A rectangular prism has a volume of 16y4 + 16y3 + 48y2 cubic units. Which could be the base area and height of the prism?a base area of 4y square units and height of 4y2 + 4y + 12 units
a base area of 8y2 square units and height of y2 + 2y + 4 units
a base area of 12y square units and height of 4y2 + 4y + 36 units
a base area of 16y2 square units and height of y2 + y + 3 units

Answers

We have a prism with a volume of 16y⁴ + 16y³ + 48y² cubic units.
Its volume is equal to the area of its base times its height.
Of course, for those to be the base area and height of this prism, they would have to multiply to 16y⁴ + 16y³ + 48y² cubic units.
Let's test each of these answers to see which gives us the correct volume.
--------------------------------------------------------------------------------------------------
a base area of 4y square units and height of 4y² + 4y + 12 units
We find the volume by multiplying the base area by the height...
4y(4y² + 4y + 12)
Distribute the 4y to each term inside the parentheses.
16y³ + 16y² + 48y
This is not the right volume, so these can not be dimensions of our prism.
--------------------------------------------------------------------------------------------------
a base area of 8y² square units and height of y² + 2y + 4 units
We find the volume by multiplying the base area by the height...
8y²(y² + 2y + 4)
Distribute the 8y² to each term inside the parentheses.
8y⁴ + 16y³ + 32y²
This is not the right volume, so these can not be dimensions of our prism.
--------------------------------------------------------------------------------------------------
a base area of 12y square units and height of 4y² + 4y + 36 units
We find the volume by multiplying the base area by the height...
12y(4y² + 4y + 36)
Distribute the 12y to each term inside the parentheses.
48y³ + 48y² + 432y
This is not the right volume, so these can not be dimensions of our prism.
--------------------------------------------------------------------------------------------------
a base area of 16y² square units and height of y² + y + 3 units
We find the volume by multiplying the base area by the height...
16y²(y² + y + 3)
Distribute the 16y² to each term inside the parentheses.
16y⁴ + 16y³ + 48y²
The volume fits, so these could be the base area and height of our prism.
--------------------------------------------------------------------------------------------------
D. a base area of 16y² square units and height of y² + y + 3 units

Answer:

Option 4) a base area of $16y^2$ square units and height of $y^2 + y + 3$ units
