Step-by-step explanation:

use CAH method (Cos angle = adjacent/hypotenuse)

Given adjacent = 5

Hypotenuse = 12,

$\cos(x) = \frac{adjacent}{hypotenuse} \\ \cos(x) = \frac{5}{12} \\ x = {cos}^{ - 1} ( \frac{5}{12} ) \\ = 65.4deg(nearest \: tenth)$

How does pemdas work?! It always confuses me!

const2013 [10]

So PEMDAS is order of operations basicly.

P=Parenthesis

E=Exponets

M=Multiplication

D=Division

A=Addition

S=Subtraction

For example: 2x4+(9x9)-1

When solving order of operations you ALWAYS start with the problem in the parentheses.

(9x9)=81

Now multiplication comes next so, 2x4=8

Then addition, 8+81=88

Lastly subtraction, 88-1=81

Because of the high heat and low humidity in the summer in Death Valley, California, a visitor requires about one quart of water

Ulleksa [173]

Answer:

4.4 L

Step-by-step explanation:

Given:

Water required for every 2 miles = 1 quart

Total distance traveled = 15 km

Now,

1 km = 0.621 miles

thus,

15 km = 0.621 × 15 = 9.32 miles

Therefore,

Quarts of water required for 15 km (9.32 miles) = $\frac{\textup{9.32}}{\textup{2}}$ = 4.66 quarts

also,

1 quart = 0.95 L

therefore,

4.66 quarts = 4.66 × 0.95 = 4.427 ≈ 4.4 L

Question 5 (Essay Worth 10 points)

otez555 [7]

Answer:

x = 4

Step-by-step explanation:

Given:

$\sqrt{11x+5}=7$

Square both sides:

$\implies \left(\sqrt{11x+5}\right)^2=7^2$

$\implies 11x+5=49$

Subtract 5 from both sides:

$\implies 11x+5-5=49-5$

$\implies 11x=44$

Divide both sides by 11:

$\implies 11x \div 11=44 \div 11$

$\implies x=4$
