The value of x in the triangle is (d) 7

<h3>How to solve for x?</h3>

The complete question is in the attached image.

From the attached image of the triangle, we can see that the triangle is a right triangle, and x can be solved using the following sine function

$\sin(45) = \frac{x}{7\sqrt 2}$

Evaluate sin(45)

$\frac 1{\sqrt 2} = \frac{x}{7\sqrt 2}$

Solve for x

$x = \frac{7\sqrt 2}{\sqrt 2}$

Divide

x = 7

Hence, the value of x in the triangle is (d) 7

A book sold 33,100 copies in its first month of release. Suppose this represents 7.8% of the number of copies sold to date. How

matrenka [14]

33100 = 7.8% of total
33100 = .078 x total (change from percent to decimal)
33100/.078 = total (divide both sides by decimal)

424358.9 = total

Round to 424,359 copies.

How much did you invest if you earned $131.60 in interest at a rate of 4% for seven years?

Ket [755]

The amount invested is $ 470

<h3><u>Solution:</u></h3>

Given that , we have earned $131.60 as simple interest for an amount deposit at the rate of 4% for seven years.

We have to find the amount invested. That is, we need to find the principal sum

Let us use the simple interest formula

<em><u>The simple interest is given as:</u></em>

$\text { Simple interest }=\frac{p r i n c i p a l \times \text {rate of interest } \times \text {number of years}}{100}$

Here, simple interest = $ 131.60

Rate of interest = 4 %

Number of years = 7

principal = ?

Substituting the values in formula, we get

$\begin{array}{l}{131.6=\frac{\text { principal } \times 4 \times 7}{100}} \\\\ {131.6 \times 100=\text { principal } \times 4 \times 7} \\\\ {13160=\text {principal } \times 28} \\\\ {\text {Principal }=470}\end{array}$

Thus the amount invested is $ 470
