What is the slope of -5,6 and -9,-6

The cost of purchasing the number of shirts after discount and sale tax is $40.3125.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

The discount is 25%.

The total price before the coupon is $50.

The sale tax is 7.5%

The cost of purchasing the number of shirts after discount will be

[tex]\rm Cost = 50*(1-0.75 )\\\\Cost = 97.5[/tex]

The cost of purchasing the number of shirts after the sale will be

[tex]\rm Cost = 37.5*(1.075)\\\\Cost = 40.3125[/tex]

The cost of purchasing the number of shirts after discount and sale tax is $40.3125.

Explanation:

For the first box, we add the two values 90 and 150 to get 240.

The same goes for the second box as well, except we cannot combine n and p together. We leave it as n+p. If we knew what numbers replaced n and p, then we could simplify further.

Answer:

x = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

[tex]\frac{1}{x}[/tex] = 5 ( multiply both sides by x to clear the fraction )

1 = 5x ( divide both sides by 5 )

[tex]\frac{1}{5}[/tex] = x

Answer:

False.

Step-by-step explanation:

It is false because when dividing an odd number by an odd number, it usually isn't divisible. In this case, 690,269. Is an odd number, because the last number, 9, is odd, which makes the whole thing odd. So, odd divided by odd never turns out well. (By the way the answer is 76,696.5555556).

Answer:

AB and CD would be 30

AC and BD would be 16

Step-by-step explanation:

The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.

Answer:

1,152 (Yes, I know it seems like a lot but it’s correct)

Step-by-step explanation:

To find this answer, we need to do 32x36

Whenever you have a problem like this, you have to multiply all your different variables/factors in which in this case is 32 and 36

When you do this, you get 1,152 so that’s your answer!

Hope this helps and please award brainliest if possible!

Answer:

1,152

Step-by-step explanation:

It is because 36 pencils and 32 students so you multiply and get 1,152

Answer:

D. 14 units

Step-by-step explanation:

it is a rectangle.

that means both diagonals are equally long.

E is in the middle of of diagonals.

so, since the whole diagonal (AC = DB) is 28 units long, one half of such a diagonal (AE = EC = DE = EB) is then

28/2 = 14 units long.

Answer:

30 + 5y

Step-by-step explanation:

Distribute the 5

5*6 = 30

5*y = 5y

and add

Answer:

[tex]5y+30[/tex]

Step-by-step explanation:

This equation on the left wants us to use the distributive property. That means we can distribute 5 to the 6, and the y in the equation. So, we will multiply.

[tex]5(6)=30\\5(y)=5y[/tex]

And, it wants us to add the two, so therefore it would be [tex]5y+30[/tex]

Answer:

a. $70.43

b. 23.43 + 13.92 + 32.98 = t (UNSURE)

Step-by-step explanation:

Since Mrs. Thomas is driving 231 miles using 23 miles per gallon, let's start by dividing 231 by 23

[tex]\frac{231}{23} = 10.043....[/tex]

We need to round 10.043... to 11 because you can't get part of a gallon.

Now, we need to multiply 2.13 by 11 to get the total amount of money for gasoline.

[tex]11 * 2.13 = 23.43[/tex]$

We also have the aditional meal expenses, which are $13.92 and $32.98.

We can use an equation to solve. Our total amount will be represented by t.

[tex]23.43 + 13.92 + 32.98 = t[/tex]

[tex]t = 70.43[/tex]

Hope this helps! Part b seems a bit confusing. I'll fix my answer if you could clarify, like if I do "communative property" or write equation. :))

Answer: 50

Let's first of all assume the son's age as x.

So,

Father's age will be 2x i.e. twice as old as the son

Given that,

Sum of their ages = 75 years

So,

x + 2x = 75

3x = 75

x = 75/3

x = 25

Hence,

Son's age = x = 25 years

Father's age = 2x = 2 * 25 = 50 years

Answer:

Step-by-step explanation:

Answer:

[tex]\frac{1}{26}[/tex]

Step-by-step explanation:

There are 26 letters in the alphabet. The computer chooses randomly, so everytime it picks a letter, out of all the 26 there is only one first letter of your name.

So, there should be a

[tex]\frac{1}{26}[/tex]

chance that the first letter in your name will be picked.

Answer:

f(x)=2x−5 if x≤−3

Since the value of x is -3, the first function will be the correct option.

Step-by-step explanation:

The given function is -

f(x)=2x−5 if x≤−3

f(x)=−3x+4 if x>−3

Now we have to evaluate f(-3).

Since we have to calculate the value of f at x = -3, we have to choose the first function.

That is f(x) = 2x - 5.

Hence,

f(−3)=2∗(−3)−5=−6−5=−11

Therefore we have the value

f(−3)=−11

Since the domain of the function is divided into two parts, we have to choose any one function for a given value of x,

For values of x less than or equal to -3, we will use the first function. That is,

f(x)=2x−5 for all x∈(−∞,−3]

And for values of x greater than -3, we will use the second function. That means,

f(x)=−3x+4 for all x∈(−3,∞)

Check the picture below.

Answer:

a₈₈ = - 431

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 4 and d = a₂ - a₁ = - 1 - 4 = - 5 , then

a₈₈ = 4 + (87 × - 5) = 4 + (- 435) = 4 - 435 = - 431

Step-by-step explanation:
