Answer:

$\frac{1}{16}$ or in decimals: 0.0625

Step-by-step explanation:

4*4*4 is 4³ or 16*4 or 64

4*4*4*4*4 is $4^{5}$ or 16*16*4 or 256*4 or 1024

We have $\frac{64}{1024}$ which divided by 8 is $\frac{8}{128}$ which divided by 8 again is $\frac{1}{16}$

write an equation to find the amount of simple interest, earned on a 600 dollar investment after 9 months, of the interest rate

tatuchka [14]

Equation:
A = P(1 + rt)
How to do it:
First, converting R percent to r a decimal
r = R/100 = 2.5%/100 = 0.025 per year,
putting time into years for simplicity,
9 months ÷ 12 months/year = 0.75 years,
then, solving our equation
A = 600(1 + (0.025 × 0.75)) = ___
What is it?

What is the value of b in the equation (y Superscript b Baseline) Superscript 4 Baseline = StartFraction 1 Over y Superscript 24

shusha [124]

The value of b is -6.

Explanation:

The expression is $\left(y^{b}\right)^{4}=\frac{1}{y^{24}}$

To determine the value of b, we shall solve the expression.

Applying exponent rule, $\left(a^{b}\right)^{c}=a^{b c}$ , we get,

$y^{4b}=\frac{1}{y^{24}}$

Applying exponent rule, $\frac{1}{a^{b}}=a^{-b}$ , we have,

$y^{4b}=y^{-24}$

The expression is of the form, $a^{f(x)}=a^{g(x)}$ then $f(x)=g(x)$

Applying this rule, we get,

$4b=-24$

Dividing both sides by 4, we have,

$b=-6$

Hence, the value of b is -6.

You blow a bubble in the shape of a sphere. It has a radius of 5 inches. Which choice is closest to its surface area? Use 3.14 t

vredina [299]

The formula to find the surface area of a circle is: pi x radius², so if we square the radius the answer would be 25, then we multiply that by 3.14 and the answer would be around 78.5, so the answer is 78.5.
