sweet [91]

Answer:

She work 23 hours.

Step-by-step explanation:

Given:

Tracy works at the Pizza Place. She earns $4.50 an hour plus tips.

Last week, she earned a total of $156.00, of which $52.50 was tips.

Now, to find the number of hours she work.

Total salary = $156.00

Amount of tips = $52.50.

So, first we deduct the amount of tips from the total salary:

$\$156.00-\$52.50\\=\$103.50.$

Thus, the remaining salary = $103.50.

As, given salary she earns an hour = $4.50.

And then, to get the number of hours she work last week by dividing $103.50 the remaining salary by $4.50:

$103.50\div 4.50$

$=23\ hours.$

Therefore, she work 23 hours.

A right triangle has legs of length 4x and 20x. What is an expression for the hypotenuse of the right triangle

kherson [118]

Answer:

$4x\sqrt{26}$ .

Step-by-step explanation:

Given information:

$Leg_1=4x$

$Leg_2=20x$

According to the Pythagoras theorem,

$(hypotenuse)^2=(Leg_1)^2+(leg_2)^2$

Using Pythagoras theorem, we get

$(hypotenuse)^2=(4x)^2+(20x)^2$

$(hypotenuse)^2=16x^2+400x^2$

$(hypotenuse)^2=416x^2$

Taking square root on both sides.

$hypotenuse=\sqrt{416x^2}$

$hypotenuse=4x\sqrt{26}$

Hence, the expression of the hypotenuse is $4x\sqrt{26}$ .

The equation of line AB is y = 5x + 1. Write an equation of a line parallel to line AB in slope-intercept form that contains poi

Zolol [24]

Answer:

The equation of the line y= 5x+1. Line that is parallel to the function given should have the same slope as the equation which is 5. We use the point-slope form in order to find the second equation that contains the point (4,5).

y - 5 = 5(x-4)

y = 5x - 20 +5

y≈ 5x -15
