Answer:

10 is your answer.

Step-by-step explanation:

Both 843 and 84 will be turned to 800/80 because 4 is below 5 so it will be turned into a zero and the 8 left an 8.

800/80=10 is your answer.

Solve log525 = x 2 1/2 -2

elixir [45]

Answer:

x = 1/2

Step-by-step explanation:

The equation in correct format is:

$log_{5}(25)=x$

We have to solve this logarithmic equation to find the value of x. This can be done by using the rules of logarithm i.e the power rule and same base rule shown below:

$log(a)^{b}=b \times log(a)\\\\log_{a}(a)=1$

Using these rules on our equation, we get:

$log_{5}(25)=x\\\\log_{5}(5^{\frac{1}{2} })=x\\\\ \frac{1}{2} log_{5}(5)=x\\\\ \frac{1}{2} (1)=x\\\\ x=\frac{1}{2}$

Thus the value of x would be 1/2

When 1,250 superscript three-fourths is written in its simplest radical form, which value remains under the radical?

Mars2501 [29]

The number that still remains under the radical when the expression is in its simplest form is 8.

<h3>What is a radical?</h3>

A radical refers to a root form. In this case, we can write this number as; 1,250^3/4.

If we try to simplify this in line with the laws of indicies, we have; 4√(1250)^3. If we simpify further, we obtain; (125)4√8.

Thus, the number that still remains under the radical when the expression is in its simplest form is 8.

Consider the problem: Jasmine wants to buy a brand new pair of headphones that cost $99. While she already has $40 saved up, she

GalinKa [24]

The number of hours that Jasmine can work so she can afford the new headphones x = 6 weeks.

let x represent the number of weeks it will take to save enough money.

If she saves $11 each week, then in x weeks she will save 11x dollars.

Add this to the 107 she has already saved, and at the end of 11 weeks she will have

11x + 107 dollars.

We want the amount saved to be equal to the price of the bike, so our equation is

11x + 107 = 173

In a word problem, writing the equation is usually the hardest part. Now we solve the equation.

Subtract 107 from both sides to get

11x = 66

Divide both sides by 11 to get

x = 6 weeks.

5/8 of the 64 musicians in a music contest are guitarists. Some of the guitarists play jazz solos, and the rest play classical s

mash [69]

Now, let's start with the Guitarists: they are 5/8 of the 64 musicians, that is

64* $\frac{5}{8} =8*5=40$

now, some number to 40 (total number of the guitarists) has the ratio of 1:4
ratios remain equivalent if we multiply both numbers by the same number.

so the ratio of 1:4 is equivalent to 10:40.

this means that there are 10 Jazz solos guitarists.

And how many classical solo guitarists were there? the rest! 40-10=30

so the answer is 30
