Answer:

Step-by-step explanation:

We subtract 3 from both sides to get rid of x and when we do so we get x = 7 - 3 = 4.

Emerson struck out 112 times in 350 at-bats. What is the percent of strike outs per at-bat?

Natasha2012 [34]

We are told that Emerson struck out 112 times in 350 at-bats. We are asked to find the percent of strike outs per at-bat.

Let us find out 112 is what percent of 350.

$\text{Percentage of strike outs per at-bat}=\frac{112}{350} \cdot 100$

$\text{Percentage of strike outs per at-bat}=0.32 \cdot 100$

$\text{Percentage of strike outs per at-bat}=32$

Therefore, Emerson struck out 32% of the at-bats.

Solve for x. 83 = 35^x Express the answer to the hundredths place (i.e., two digits after the decimal point). x =

devlian [24]

Answer:

x = 1.24

Step-by-step explanation:

In order to get that x down from its current position of exponential, you need to take either the log or the natural log of both sides. The power rule tells us that we can then pull the exponent down in front. So let's take the natural log of both sides:

$ln(83)=ln(35)^x$

We can bring the x down in front to give us:

ln(83) = x ln(35)

The right side of this is "stuck" together by multiplication, so we can undo that multilication by division of the ln(35). That leaves us with just x on the right:

$\frac{ln(83)}{ln(35)}=x$
