I’m going to Mcshoot myself pls help

### Answers

**Answer:**

x = 10.8

**Explanation:**

[tex]\sf \sf cos(x)= \dfrac{adjacent}{hypotensue}[/tex]

**using cosine rule:**

[tex]\rightarrow \sf cos(26)= \dfrac{x}{12}[/tex]

[tex]\rightarrow \sf x = cos(26) *12[/tex]

[tex]\rightarrow \sf x =10.8[/tex]

**Answer:**

The answer is rounded 10.8

**Step-by-step explanation:**

Cosine is the adjacent side over the hypotenuse, or a/h. So, cos 26=x/12. To solve for x, isolation of the variable is necessary. If both sides are multiplied by 12, the equation becomes 12 (cos 26)=x. The cosine of 26 is 0.8988, which multiplied by 12 is 10.8.

In 2005, 12.2 out of every 50 employees at a company were women. If there are 48,744 total company employees, estimate the number of women.

### Answers

**Answer:**

12000

**Step-by-step explanation:**

Using this information, you can make a ratio: 12.2/50 = x/48744

By simplifying this ratio you get that 50x = 594676. Dividing both sides by 50 you get about 11900, which you can round up to 12000

**Answer:**

11,894 women

**Step-by-step explanation:**

ratio of women to employees = 12.2 : 50

Let x = number of women employees to 48744 employees

12.2 : 50 = x : 48744

⇒ 12.2 / 50 = x / 48744

⇒ 0.244 = x / 48744

⇒ x = 0.244 · 48744

⇒ x = 11893.536

⇒ x = 11894 (nearest whole number)

Therefore, there are approximately 11,894 women in a company with a total of 48,744 employees

Benjamin has 3 dimes and 4 nickels. What percent of a dollar does he have?

### Answers

**Answer:**

50%

**Step-by-step explanation:**

Hope this helped

*Maybe mark brainiest*

Dime = 10 cents

Nickel = 5 cents

Total value of coins = 3(10) + 4(5) = 30 + 20 = 50

To find the percent, first create a fraction. The fraction will be the amount of money that Benjamin has over the total (one dollar).

50 / 100 = 5 / 10 = 0.5

0.5 x 100 = 50

50%

**Answer: **50% of a dollar

a boy agreed to work one year for 1200 and a horse at the end of six months he quit and received 400 plus the horse what was the value of the horse

### Answers

The **cost** of the horse given the **amount received** at the end of 6 months is **600**

How to find the value of the horse?

let

**h** = value of the horse

6/12 × 1200 + 6h/12 = 400 + h

700 + 6h / 12 = 400 + h

700 - 400 = h - 6h/12

300 = 12h - 6h / 12

300 = 6h/12

cross **product**

300 × 12 = 6h

3600 = 6h

h = 3600 / 6

**h = 600**

Which two expressions are equivalent to 8(6x + 9)

A. 8(6x) + 8(9)

B. 8(6x) + 9

C. 14x + 17

D. 48x + 17

E. 48x + 72

### Answers

**Answers: Choice A and Choice E **

Explanation:

The distributive property allows us to go from the original expression to choice A. We multiply the outer term 8 by each term inside the parenthesis.

In general, the distributive property is a(b+c) = ab+ac. Example: 2(3+4) = 2(3)+2(4) = 6+8 = 14.

After simplifying the expression in choice A, it leads directly to choice E. This is because 8(6x) = 48x and 8(9) = 72.

Side note: A common mistake students do is to multiply the outer term by only one of the terms inside the parenthesis, while forgetting about the other term inside. Choice B shows this mistake. It's possible your teacher put choice B in there as a trap/trick answer.

An isosceles triangle has an angle that measures 38degrees. What measures are possible for the other two angles? Choose all that apply.

### Answers

**Answer:**

71° and 71°.

⠀

**Step-by-step explanation:**

The triangle having two sides equal along with one different side is called an isosceles triangle.

⠀

So, Let us assume the other sides (two equal sides) of the isosceles triangle as x. As the different side is already given in the question.

⠀

We know that,

The sum of all angles of a triangle is 180°

⠀

So, **According to the question :**

⠀

[tex]{\longrightarrow \it\qquad { \ { { 38 \: }^{ \circ} + x + x = 180{}^{ \circ} }}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \ { { 38 \: }^{ \circ} + 2x = 180{}^{ \circ} }}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \ { 2x = 180{}^{ \circ} - { 38 \: }^{ \circ}}}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \ { 2x = 142{}^{ \circ} }}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \ { x = \dfrac{142{}^{ \circ}}{2} }}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \pmb { x = 71^{ \circ} }}}[/tex]

⠀

Therefore,

The measure of the two other angles of the isosceles triangle are **71°** and **71°.**

**Answer:**

1) There were 120 customers per night when the restaurant opened

2) y = -2x + 24

**Step-by-step explanation:**

1) x represents the # of months since a restaurant opened, and y represents the average number of nightly customers.

y=mx+b

120 is *b* in this situation, which is the y-intercept of the line. This means that 120 is the starting number of customers when the restaurant first opened.
