Answer:

$338.20

Step-by-step explanation:

First, lets find out how much Kim makes in 1 hour

SO, we can do $89÷10 which is $8.9 per hour

Then, we can multiply that by 38

So, 8.9*38=$338.20

Galina-37 [17]

Since they are similar triangles, they are just enlarged versions of each other. This means that the left-most angle of triangle XYZ is also 35°.

Angles in a triangle add up to 180°, so we can find the missing angle by subtracting the two known angles from 180.

180 - 70 - 35 = 75
The right-most angle of triangle XYZ would be 75°.

Hope this helps!

Select the statement that is true about squares from the choices below.

Leya [2.2K]

The answer is (C). All sides and angles of the square is equal. Its diagonals bisect each other and meet at 90°. If two lines are said to meet at 90°, these lines are perpendicular to each other. Therefore, the diagonals of a square is perpendicular to each other

A seamstress is making a decorative pillow and wants to cover both sides of the pillow with special fabric. The pillow is

Cloud [144]

The three points form a right triangle with legs length 3in and 4in. So, the area is

$\dfrac{3\cdot 4}{2}=6$

So, both sides of the pillow will require 12 squared inches.

A motorboat travels 172 km in 3 hours going upstream and 372 in 4 hours going downstream. What is the rate of the boat in still

torisob [31]

Answer:

<em>The rate of the boat is 75.17 km/h and the rate of the stream is 17.83 km/h</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's call:

B = speed (rate) of the boat in still water

S = speed (rate) of the stream

The boat travels 172 km in 3 hours when going upstream, that is when the speed of the stream subtracts its own speed. The speed is the distance divided by the time, thus:

$\displaystyle B-S=\frac{172}{3}$

Multiplying by 3:

3B - 3S = 172 [1]

The boat travels 372 km in 4 hours downstream when the speed of the current adds to its own:

$\displaystyle B+S=\frac{372}{4}=93$

B + S = 93

Solving for B:

B = 93 - S [2]

Substituting in [1]

3(93 - S) - 3S = 172

Operating:

279 - 3S - 3S = 172

279 - 6S = 172

Subtracting 279:

- 6S = 172 - 279

- 6S = -107

Multiplying by -1 and solving for S:

$S = \frac{107}{6}\approx 17.83\ km/h$

From [2]:

$B = 93 - \frac{107}{6}$

$B=\frac{451}{6}\approx 75.17\ km/h$

What is the length of each side?label each side with an expression that represents its length

3241004551 [841]

The three consecutive sides are

x
x + 1
x + 2

Set up:

x + x + 1 + x + 2 = perimeter

Solve for x.

After finding x, substitute your value of x back into the three consecutive integers to find your answer.
