Which equation can be used to solve for b?<br> B<br> 5 cm<br> 10 cm<br> 30°

kati45 [8]

The Question is Incomplete The complete question with figure is below.

Answer:

Therefore the equation to solve for b is

$\tan 30 = \dfrac{5}{b}$

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

∠C = 90°

BC = 5 cm

AB = 10 cm

∠A = 30°

To Find:

b = ?

Solution:

In Right Angle Triangle ABC Tangent identity we have

$\tan A = \dfrac{\textrm{side opposite to angle A}}{\textrm{side adjacent to angle A}}$

Substituting the values we get

$\tan 30 = \dfrac{BC}{AC}\\\\\tan 30 = \dfrac{5}{b}$

Therefore the equation to solve for b is

$\tan 30 = \dfrac{5}{b}$

To rent a moving truck there is a fee of $150 and each mile you drive costs an extra $1.75 per mile, where R(x) is the total cos

abruzzese [7]

Answer:

$318

Step-by-step explanation:

First, we want to set up an equation to solve this problem by using the information given to us. We're asked for the total cost, so we want one side of the equation to be $R(x)=$ . Then, we know that the initial cost is $150, no matter how many miles we drive. We are also told that each mile is $1.75.

$R(x)=150+1.75x$

The problem tells us that we are driving 96 miles, so we can plug in 96 for $x$ and solve.

$R(x)=150+1.75(96)\\R(x)=150+168\\R(x)=318$

The total cost of the rental is going to $318.

Hope this helps!

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.
