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%

Answers

Answer:

A secant line contains a chord always

Step-by-step explanation:

A line intersecting in two points is called a secant line, in one point a tangent line and in no points an exterior line. A chord of a circle is the line segment that joins two distinct points of the circle. A chord is therefore contained in a unique secant line and each secant line determines a unique chord.

Solve: y = x + 2
y + 1 = - 4x
On paper

Answers

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

HELP PLZZ I FORGOT HOW TO DO THIS!!!! What is the surface area of the square pyramid represented by the net?

Enter your answer in the box.

Answers

Answer:

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)

= [tex]3^{2}[/tex] = 9[tex]ft^{2}[/tex]

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

Steve made $ 125 mowing lawns. He gave 60% of his earnings to his mother. How much did Steve give to his mother?
(if you answer this may you please show your work)

Answers

x/125 = 60/100 then 125x60= 7500/100 = $75

Answer:

$75

Step-by-step explanation:

60% is also 0.6. Multiply 0.6 x 125 to get 75. You multiply because they're asking 60% (0.6) of (x) his earnings (125).

A recipe calls for 3 cups of flour to make 2 batches of dinner rolls. One batch makes 15 rolls. Laura is making dinner for 12 people and only needs one roll per person.
What proportion will help Laura find how much flour is needed to make 12 dinner rolls?
A. 3/30 = x/12
B. 3/2 = x/12
C. 3/15 = x/12
D. 12/15 = x/3

Answers

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.

A. 3/30=x/12
Or B 3/2 = x/12
