If r^n=a, then which of the following are true statements? Check all that apply.

Vanyuwa [196]

A. This is correct. When you transfer n to the other side, that would be the reciprocal power of a.

b. This is incorrect, because this contradicts with choice a.

c. This is correct. When a number is raised to a "1/n" fraction, that is equivalent to the nth root of the number.

d. This is incorrect, because it is not equivalent to the given equation.

<em>Thus, the answers are A and C.</em>

Work out the area of the shaded region.

Makovka662 [10]

Answer: Area of the shaded region is 6.867 square cm

Step-by-step explanation:

The shaded area corresponds to the difference of the area of the rectangle and the area of the semicircle.

Area of the rectangle = 4 times 8 = 32 cm^2

Area of the semicircle = 0.5 * pi * r^2 (where r is the radius, i.e., half of the diameters, i.e., 4 cm). So Area = 0.5*pi*4^2 = 25.133 cm^2

The difference: 32 - 25.133 = 6.867 cm^2 (area of the shaded region)

I need to drink 8 2/4 cups of water and 2 1/5 cups milk every day. How much fluid do I have to drink?

lidiya [134]

Answer:

The total fluid you have to drink is 10 7/10 = 10.7 cups.

Step-by-step explanation:

The daily requirement of water = 8 2/4 cups

Now, $8 \frac{2}{4} = 8+ \frac{2}{4} = 8+ 0.5 = 8.5$

or, the daily water requirement = 8.5 cups

The daily requirement of milk = 2 1/5 cups

Now, $2 \frac{1}{5} = 2+ \frac{1}{5} = 2+ 0.2 = 2.2$

or, the daily milk requirement = 2.2 cups

So, The total fluid needed = Cups of (Water + Milk) needed

= 8.5 cups + 2.2 cups

= 10.7 cups

Also, $10.7 = 10 + 0.7 = 10 + \frac{7}{10} = 10\frac{7}{10}$

Hence, the total fluid you have to drink is 10 7/10 cups.

a small bridge sit atop for cube shaped powers that all have the same volume. The combined volume of the four pillars is 503 how

Natasha_Volkova [10]

Answer:

60 inches long are the sides of the pillars.

Step-by-step explanation:

Given : A small bridge sits atop four cube shaped pillars that all have the same volume. the combined volume of the four pillars is 500 ft cubed.

To find : How many inches long are the sides of the pillars?

Solution :

Refer the attached picture below for Clarence of question.

The volume of the cube is $V=a^3$

Where, a is the side.

The combined volume of the four pillars is 500 ft cubed.

The volume of each cube is given by,

$V=\frac{500}{4}=125\ ft^3$

Substitute in the formula to get the side,

$125=a^3$

$a=\sqrt[3]{125}$

$a=5\ ft$

We know, 1 feet = 12 inches

So, 5 feet = $5\times 12=60$ inches

Therefore, 60 inches long are the sides of the pillars.
