Step-by-step explanation:

15v = 75

15v/15 = 75/15 Divide 15 on both sides in respect to v

v = 5

If the length of two sides of a triangle are 7 and 10, the length of the third side may be

Kitty [74]

Answer:

The Triangle Inequality Theorem rule states that when you add 2 sides they must be greater than the third side,

Your third side has to be less than 7+10=17

Your third side is less than 17 and greater than 3

Anything that is 17 or greater is to big

Anything that is 3 or less is to small

So your answer is between 4-16

Answer:

16.6% ; 3.2%

Step-by-step explanation:

Given the data :

Data A:

$36,700, $30,300, $22,800, $27,700, $37,700, $39,800, $27,000, $30,100, $33,900, $24,900, $27,500, $37,600, $32,700, $34,200

Data B: 21,253, 21,065, 20,747, 21,905, 20,546, 21,580, 22,292, 20,072, 20,518, 20,426, 20,839

The Coefficient of variation (CV) = (Sample standard deviation / Sample mean)

Sample mean (m) ;

Σx / n

n = sample size

Sample standard deviation (S) :

√[(x - m)² / (n-1)]

To save computation time ;

The sample mean and sample standard deviation can be obtained using a calculator :

For Data A:

Sample mean (m) = 31635.7143

Sample Standard deviation (s) = 5256.14763

Hence, Coefficient of variation :

5256.14763 / 31635.7143

= 0.166

= 0.166 * 100% = 16.6%

For Data B:

Sample mean (m) = 21022.0909

Sample Standard deviation (s) = 678.718271

678.718271 / 21022.0909

= 0.032

= 0.032 * 100% = 3.2%

liam makes soap sculptures of sea turtles each sculpture weighs 3\8 pounds he ships then in a wooden box that weighs 2 pounds th

Tresset [83]

We have been given that Liam makes soap sculptures of sea turtles each sculpture weighs 3/8 pounds. He ships them in a wooden box that weighs 2 pounds. The total weight of the box filled with the sea turtles is 5 pounds.

We are asked to find the number of sea turtles in the box.

First of all, we will subtract the weight of the box from total weight to find the weight of all sea turtles.

$\text{Weight of sea turtles}=\text{Total weight}-\text{Weight of box}$

$\text{Weight of sea turtles}=\text{5 pounds}-\text{2 pounds}$

$\text{Weight of sea turtles}=3\text{ pounds}$

Now we will divide total weight of all turtles by weight of one turtle to find number of turtles.

$\text{Number of turtles}=\frac{\text{Weight of all sea turtles}}{\text{Weight of one turtle}}$

$\text{Number of turtles}=\frac{3}{\frac{3}{8}}$

$\text{Number of turtles}=\frac{3\cdot 8}{3}$

$\text{Number of turtles}=8$

Therefore, there are 8 sea turtles in the box.

Solve x + 9 = 18 - 2x

bezimeni [28]

Add 2x to both sides,
3x+9=18
Subtract 9 from both sides. 3x=9
Divide both sides by 3.
x=3
