7 times x to the three fourths power in radical form is Fourth root of quantity 7 times x to the third power.

So, Option C is correct.

Step-by-step explanation:

We need to write 7 times x to the three fourths power in radical form

First writing 7 times x to the three fourths power in mathematical form:

$7x^{\frac{3}{4}$

Writing it into radical form:

$7x^{\frac{3}{4}$

We know 1/4 = $\sqrt[4]{}$

So,

$\sqrt[4]{(7x)^3}$

Writing it into words:

Fourth root of quantity 7 times x to the third power.

So, 7 times x to the three fourths power in radical form is Fourth root of quantity 7 times x to the third power.

So, Option C is correct.

Jay is letting her bread dough rise. After three hours, her bread dough is \dfrac{11}{5} 5 11 start fraction, 11, divided by,

timama [110]

Answer:

Jay's bread size is 220% of the original size.

Step-by-step explanation:

The question is incomplete.

The complete question is as follows.

Jay is letting her bread rise. After 3 hours,her bread is at 11/5 of its original size. What percent of its original size is jays bread dough?

Solution:

Let the original bread size be = $100$ units

After 3 hours the bread rises = $\frac{11}{5}$ of the original size

New size of bread = $\frac{11}{5}\times 100=220$ units

Percent of original size the new bread is

⇒ $\frac{New\ bread\ size}{Original\ bread\ size}\times 100$

⇒ $\frac{220}{100}\times100$

⇒ $220\%$

An aircraft has a total time in service of 468 hours. The Airworthiness Directive given was initially complied with at 454 hours

Georgia [21]

Answer:

440 hours

Step-by-step explanation:

In this case the aircraft has completed one cycle of service in the first 454 hours of service. Then making the difference between the hours of service and the hours of the first cycle we have:

Hours of the second cycle= Total time in service- time Airworthiness Directive

=468-454=14

Then we have 14 hours of service and need to accumulate the rest to complete 454. It is

454-14=440

Then we need to accumulate 440 hours additional to complete the Airworthiness Directive .

What is the nth term of the geometric sequence -2,10,-50

poizon [28]

Answer:

$T_n=-1(-5)^n^-^1$

Step-by-step explanation:

We are given;

A geometric sequence;

-2,10,-50

Required to determine the nth term

The nth term in a geometric sequence is given by the formula;

$T_n=a_1r^n^-^1$

where $a_1$ is the first term and r is the common ratio;

In this case;

$a_1=-2$

r = 10 ÷ -2

= -5

Therefore;

To get the nth term in the given geometric sequence we use;

$T_n=-1(-5)^n^-^1$

Thus, the nth term is $T_n=-1(-5)^n^-^1$

What is the value of x in the equation 2x + 1/2x + 2(1+x) = 29?

erica [24]

Answer:

Step-by-step explanation:

$2x + \frac{1}{2} x + 2(1 + x) = 29$

Multiply through by 2

That's

$4x + x + 4(1 + x) = 58$

<u>Expand</u>

That's

5x + 4 + 4x = 58

9x = 58 - 4

9x = 54

Divide both sides by 9

That's

$\frac{9x}{9} = \frac{54}{9}$

We have the final answer as

Hope this helps you
