Answer:

${b}^{4} + 1$

Your teacher messed up the question so just put the top right answer and ask your teacher if they did accidently miss-type.

Step-by-step explanation:

The first thing to do in this equation is look at the exponents. When multiplying a variable (or any number equal to itself with the same exponent) you only have to add the exponent. So for a, you would add the exponents to get 0, so a to the power of 0 is 1, because any number to the power of 0 is 1. For b, we would add the 3 and 1. (When no exponenet is present in a number then it is 1, so for this I added 3 and 1). So it would be 4. The correct answer is

${b}^{4} + 1$

cooper's jump rope is for 4 2/5. luke's jump rope is 4 3/4 ft long. whose jump rope is longer? how much longer? show your work

Hoochie [10]

Answer:

Juke's jump; by 0.35 feet

Step-by-step explanation:

Given that,

Cooper's jump rope is for $4\dfrac{2}{5}$ feet.

Juke's jump rope is $4\dfrac{3}{4}$ feet.

Cooper's jump is :

$4\dfrac{2}{5}=\dfrac{22}{5}\ \text{feet}\\\\=4.4\ \text{feet}$

Juke's jump is

$4\dfrac{3}{4}=\dfrac{19}{4}\\\\=4.75\ \text{feet}$

So, it is clear that Juke's jump is longer than Cooper's jump.

Juke's jump - Cooper's jump = 4.75 - 4.4

= 0.35 feet

So, Juke's jump is 375 feet longer.

how many triangles can you make with the given lengths of three line segments are 4 centimeters, 5 centimeters, and 9 centimeter

netineya [11]

None. The triangle inequality states that the sum of the smaller two sides of a triangle must be greater than the third side. As 4+5=9, this inequality is false in this case, so these sides cannot create a triangle.

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y

dsp73

Y=k/x²; substitute x=1 and y=1/8: 1/8=k. So y=1/(8x²)
When x=5, y=1/(8×25)=1/200.

Please help with the question 2 to 18

vladimir1956 [14]

Since these questions all require similar methods of solving, I will only completely work out the first question of each type.

2. To find $\frac{7}{10}$ as a decimal, all we need to do is complete the fraction by dividing the numerator by the denominator.

$\frac{7}{10}$ = 7 / 10 = 0.7

$\frac{7}{10}$ as a decimal is 0.7.

3. To write a fraction as a percentage, we must first convert it into a decimal, the way we did in problem 2.

$\frac{13}{20} =0.65$

Then to change that number into a percentage, we can either multiply it by 100, or (my personal shortcut) just shift the decimal point over two places to the right.

0.65 = 65%

which is the answer to question 3.
$\frac{13}{20}$ written as a percent is 65%.

4. Writing a percentage as a fraction is a bit easier than writing a fraction as a percentage. All you need to do is place the percentage in the numerator's place of a fraction with 100 as the denominator and simplify.

2%5 = $\frac{25}{100}$

Since 25 goes into 100 four times, we can simplify this fraction.

$\frac{25}{100} = \frac{1}{4}$

which is our answer.

25% written as a fraction is $\frac{1}{4}$ .

5. This is the same as problem 3, so I won't show my work for the sake of time.

$\frac{2}{5}$ as a percentage is 40%.

6. This is the same as problem 1, so I will not show steps again.

$\frac{3}{20}$ as a decimal is 0.15.

7. Done similar problems in past. No work shown.

$\frac{21}{50}$ as a percent is 42%.

8. Same as last problem.

$\frac{1}{25}$ as a percent is 4%.

9. Same as number 4.

6% as a fraction is $\frac{3}{50}$ .

10. Similar in past.

$\frac{3}{5}$ as a percentage is 60%.

11. Same as 6.

$\frac{12}{25}$ as a decimal is 0.48.

12. Done a lot of these so far.

$\frac{3}{10}$ as a percentage is 30%.

13. Just did one like this.

$\frac{3}{4}$ as a percentage is 75%.

14. Same as 4 and 9.

65% as a fraction is $\frac{13}{20}$ .

15. Plenty of these done in past.

$\frac{1}{5}$ as a percentage is 20%.

16. Last problem, and it's just like the one just before this.

$\frac{9}{10}$ written as a percent is 90%.

So there are the results.
Hope that helped! =)
