10^-2 + 8 round the coefficient to two decimal places​

Mathematics

Dahasolnce [82]3 years ago

Answer:

I believe it is .0801

Step-by-step explanation:

- A negative exponent will always turn into a fraction

- First change it to a fraction

1/10^2

- Simplify the exponent

10 times 10 = 100

- Change the fraction

1/100 or in decimal form which is 0.01

- Now the addition

8 + 0.01 = <u>8.01</u>

- Move decimal to two decimal places

.0801

Answer:    .0801 is what I got because the way I understand it 10^(-2) + 8 =8.01 and you said round it to the coefficient to 2 decimal places. so I moves the 8 over 2 times because 8 is the coefficient and I got .0801

Hope it helped and I got it right

If the volume of the crystal ball is about 113.14 cm3, the radius of the ball is approximately
stellarik [79]

Answer:

r ≅ 3.00

Step-by-step explanation:

First we need to get the formula for finding the volume of sphere. The formula  is:

V=\frac{4}{3}\pi r^{3}

Now to find for the radius, we need to input the value that we know into the formula.

113.14=\frac{4}{3}\pi r^{3}

Now we multiply both sides by 3/4.

\frac{3}{4}x113.14=\frac{4}{3}\pi r^{3}

84.86=\pi r^{3}

Now divide both sides by π.

\frac{84.86}{\pi}=\frac{\pi r^{3}}{\pi}

27.01=r^{3}

To find r, we finally get the cube root of both sides.

\sqrt[3]{r^{3} }= \sqrt[3]{27.01}

r ≅ 3.00
