Which statement most reasonably explains the hours when zero calls were received? Medera turned the phone off while playing in a soccer game. Medera's phone can only receive 22 calls a day. Medera only receives calls in clusters. Medera lost her phone for two hours.

Answers

Answer:

Medera turned the phone off while playing in a soccer game.

Step-by-step explanation:

From the possible scenarios provided the one that would indicate this would be when Medera turned the phone off while playing in a soccer game. This is because since her phone was off it was not getting any phone signal which means that no incoming calls would have been received during that time. When Medara lost her phone for two hours, even though she did not have it on her the phone was still on and connected to a network which means that the calls were coming in.

infinitely many

Answers

Answer:

its b lol

Step-by-step explanation:

jus got it right

There is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

What is a linear equation?

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We have a linear equation in one-variable:

0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)

0.75(x + 40) = 0.7(x + 20)

75(x + 40) = 70(x + 20)

75x = 70x - 1600

x = -370

Hence, there is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

1. Factor the first equation.

7x³−11x²−14x+16

7x³−14x²+3x²−6x−8x+16

7x²(x-2)+3x(x-2)-8(x-2)

(x-2)(7x²+3x-8)

2. So this is as far as we have to go because as we can see x-2 is a factor of the equation.

3. Factor the second equation.

7x⁴+22x³+2x²+11

4. As we can see this equation isn’t factorable, so which means that this equation can’t have an exact root so which means x+3 is not a factor for the second equation.

Solve 6kx = 4kx + 8 for x.
Start by collecting the variable terms on the same side of the equation.

What is the first step?

Answers

Answer:

x = 4k

Step-by-step explanation:

6kx = 4kx + 8

The first step in solving for x is to get both numbers with kx on the same side. Move the 4kx to the left side of the = by subtracting 4kx from each side.

2kx = 8

Next, move the 2k to the right side of the = by dividing both sides by 2k

x = 8/2k

The last thing to do is to simplify the equation by making the 8/2 to 4/1 or 4.

x = 4k

C)-9, multiplicity 3; 9, multiplicity 2
D)-9, multiplicity 2; 9, multiplicity 3

Answers

The 3 and the 2 are just to throw you off because you can just divide them out so the first zero is -9 because you have to subtract to find x with a multiplicity of 1 since there is no power (the small number) and the second is 93 since you add it to solve for x and multiplicity of 1. Is the second part asking to make an equation for it?

Tiffany ate 1/4 of a pizza. If there were 16 slices of pizza to begin with, how many slices did Tiffany eat?​

Answers

Answer:

Tiffany ate 4 slices of pizza

Step-by-step explanation:

1/4 of 16 is 4

Tiffany ate 4 slices of pizza.

What is fraction?

" Fraction is a representation of a part of whole object which is divided into equal parts."

According to the question,

Total number of pizza slices = 16

Part of pizza ate by Tiffany   = 1 / 4

Therefore,

Number of slices Tiffany ate = ( 1/ 4) of 16

                                                = (1 / 4) × 16

                                                = 4 slices of pizza

Hence, Tiffany ate 4 slices of pizza.

Isaac bought 18 boxes of cereal. This is 30% of the total boxes at the store. How many total boxes of cereal were at the store?

Answers

Answer:

60

Step-by-step explanation:

30% of total boxes at the store is equal to 18

so

[tex](30 \div 100 ) \times x = 18 \\ x = 18 \times( 100 \div 30) = \\ 18 \times (10 \div 3) = \\ 6 \times 10 = 60[/tex]

The 18 boxes of cereal Isaac purchased. This represents 30% of all the boxes in the store then total boxes of cereal at the store exists 60.

What is meant by percentage?

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. To exstimate a percentage, you divide the portion of the whole by the whole itself and multiply by 100.

%, which is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

The total no of boxes =  y × 100/x

Given x = 30%

y = 18 boxes

Total boxes at the store = 18 × 100/30 = 60

Therefore, the total boxes of cereal at the store exists 60.

Now, they have to be equal because we are trying to find the equation for total charges.

So, your equation would be 2x + 200 = 6x + 120.

Hope this helps!

Answer:

Step-by-step explanation:

Let the number of linear feet = x

Let the total cost = y

Condition One

y = 200 + 2x

Condition Two

y = 120 + 6x

Now you want the ys to be the same.
