Answer:

800

Step-by-step explanation:

176 divided by 22=8

8x100= 800

It will take 13.33 hours to battery run out.

A unit rate means a rate for one of something.

Given that, A cell phone battery with 22% charge takes 176 minutes to run out.

In 22% → 176 minutes

In 1% → 176/22 = 8 minutes

In 100% → 8x100 = 800 minutes

800 minutes = 800/60 = 13.33 hours.

Hence, the battery will work for 13.33 hours when charged 100%

Answer:

(x ,y)= (1/3, -4/3)

Step-by-step explanation:

simplify

y = -4x

x + 2y + 1 = -4x

multiply both sides

4x + y = 0

5 x + 2y = -1

eliminate one variable

-8x - 2y = 0

5x + 2y = -1

divide

-3x = -1

x = 1/3

possible solution

y= -4/3

check the solution

(x, y) = (1/3, -4/3)

simplify

-4/3 = 1/3 + 2 x (-4/3) + 1 = -4 x 1/3

place in order

-4/3 = -4/3 = -4/3

Answer:

Step-by-step explanation:

3 cups of flour produces 2 batches of dinner rolls. So, if one batch makes 15 rolls, then 2 batches makes 30 rolls. Therefore, 3 cups of flour produces 30 rolls.

Laura wants to find how much flour she needs to make 12 rolls.

Here's the setup:

Let x be the number of cups of flour needed. Then,

(3 cups of flour)/(30 rolls)=(x cups of flour)/(12 rolls)

This is the set up for all equations involving ratios. The units should be consistent. Notice how I have flour/rolls=flour/rolls.

It is not necessary to solve the equation, but you should to make sure your answer makes sense. By cross-multiplying, we get x=(3*12)/30 or 1.2 cups.

This solution makes sense. Because 3 cups of flour produces 30 rolls, one cup produces 10 rolls. We need slightly more than 1 cup to get 12 rolls.

Answer:

Begin by factoring 2 out of   2x^2 - 2x - 12 equals 0:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0.  2 is never zero, but x-3 and x+2 can each be set = to 0:

This results in x = 3 and x = -2.  The equation is true for these two x-values.

Answer:

If you walk 3 kilometers in 30 minutes your average speed is 6 kilometers per hour.

Therefore, the avearge speed in kilometers per hour is [tex]0.1[/tex] kilometer per hour.

What is the speed?

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Here given that,

Here, you walk [tex]3[/tex] kilometers in [tex]30[/tex] minutes. So the average speed is :-

Speed = Distance/ Time

Distance is [tex]3km[/tex] and the time is [tex]30[/tex] minutes so,

[tex]S=\frac{3}{30}\\\\\\S=0.1[/tex]

Hence, the avearge speed in kilometers per hour is [tex]0.1[/tex] kilometer per hour.

39[tex]ft^{2}[/tex]

Step-by-step explanation:

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

All four triangles are similar. So finding the area of one triangle, will be the area of the other triangles.

 [tex]\frac{1}{2}[/tex] × 3 × 5 = 7.5[tex]ft^{2}[/tex]

∴ The area of 4 triangles are 7.5 × 4 = 30[tex]ft^{2}[/tex]

Then the only shape remaining is the square.

Area of the square = [tex]length^{2}[/tex] (all the sides of a square are equal)

Total surface area = 30 + 9 = 39[tex]ft^{2}[/tex]
