Answer:

Step-by-step explanation:

<1 + <3 = 90 Parallel lines produce interior angles that add to to 90

<1 + 38 = 90 Substitution

<1 = 90 - 38 52

<3 = 90 - 52

<3 = 38

38 + 63 + <2 = 180 Sum of angles in a triangle always = 180

101 + <2 = 180

<2 = 79

kolezko [41]

Answer:

1/8 quart

Step-by-step explanation:

STEPS TO DETERMINING THE ANSWER

Divide the total quarts of hot tea by the size of the mug. the remainder of the division is the leftover

$1\frac{3}{4}$ ÷ $\frac{2}{7}$

$\frac{7}{4}$ ÷ $\frac{2}{7}$

$\frac{7}{4}$ × $\frac{7}{2}$ = $\frac{49}{8}$ = $6\frac{1}{8}$

6 cups would be filled and 1/8 quart would be left over

Does anyone know this??

Mnenie [13.5K]

Answer: 21

Step-by-step explanation: To solve this problem, we can first set up a proportion because we know that 3 is to 7 as 9 is to x.

So we have $\frac{3}{7} = \frac{9}{x}$ .

Now, we can use cross products to find the missing value.

So we have 3 time x which is 3x and 7 times 9 which is 63.

Rewriting our equation, we have 3x = 63.

Dividing both sides by 3, we find that x = 21.

So, x = 21.

The red arrows in the middle mean that they are parallel so the slopes are the same.

Jennifer has a job that pays $75,000 per year. How much will she pay in Medicare taxes? (Medicare taxes are 1.45% of earnings.)

klasskru [66]

It is pretty simple,

All you have to do is multiply 75,000 by 0.0145 to find the amount of Medicare taxes
75,000x0.0145=1,087.50

The answer is that Jennifer pays $1,087.50 for Medicare taxes

I hope this helps
