Step-by-step explanation:

When Dividing fractions, use the reciprocal of 3/4

7 1/2 times 4/3 equals

10

Answer:

10

Step-by-step explanation:

You would do something called KCF Keep, Change, and Flip.

You would keep the 7 1/2 and change the divided sign to multiplying sign and flip the 3/4 so its a 4/3 and then multiply it.

15/6 times 4/3. 15 x 4 = 60

                           2x3=   6

so I can be 60/6 but you would simplify and 6 goes into 60  10 times. so 10 is you answer

After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?

Answers

Answer:

D

Step-by-step explanation:

The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.

An art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each small box contains 20 markers. Which equation could be used to find n, the total number of markers in stock?

Answers

Answer: n= 80 ×48+ 34×20

Step-by-step explanation:

Given: Number of large boxes = 80

Number of small boxes = 34

Number of markers in each large box = 48

Number of markers in each small box = 20

Total markers = (Number of large boxes)x (Number of markers in each large box) + (Number of small boxes) x (Number of markers in each small box)

Total number of markers = n (given)

Then, n= 80 ×48+ 34×20

Therefore , the equation could be used to find n, the total number of markers in stock: n= 80 ×48+ 34×20

How would u solve this??

Answers

Answer:

n=1, m=3, and p=-4

Step-by-step explanation:

Take the fourth root of both sides

so x^n*y^m*z^p=x*y^3*z^-4;

notice z has a negative exponent because it was in the denominator

therefore, n=1, m=3, and p=-4

Can you find the slope-intercept equation of each line and type the correct code? Please remember to type in ALL CAPS with no spaces.

Answers

Answer:

The answer for the code is CGIA

Step-by-step explanation:

The slope- intercept of each line is

First line,

y= x+ 2

Second line,

y = 2x +2

Third line,

y= -x +1

Fourth line,

y= -2x - 2

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

First line,

slope intercept form

(y - 3)= 1(x-1)

y= x+ 2

Second line,

slope intercept form

(y - 2)= 2(x-0)

y = 2x +2

Third line,

slope intercept form

(y + 2)= (-1)(x - 3)

y= -x +1

Fourth line,

slope intercept form

(y + 2 )= -2(x-0)

y= -2x - 2

-7, 14

Answers

Answer:

The correct answer is: -7, 7

Step-by-step explanation:

Given numbers are:

-7, 0, 7, 14

We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.

So,

[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]

We can see that the sum of -7 and 7 is zero.

Hence,

The correct answer is: -7, 7

Your answer is B.) -7, 7

Help me pleasee. Solve the system by substitution

Answers

Answer:

(3, - 2 )

Step-by-step explanation:

Given the 2 equations

4x - 2y = 16 → (1)

y = - 5x + 13 → (2)

Substitute y = - 5x + 13 into (1)

4x - 2(- 5x + 13) = 16 ← distribute and simplify left side

4x + 10x - 26 = 16

14x - 26 = 16 ( add 26 to both sides )

14x = 42 ( divide both sides by 14 )

x = 3

Substitute x = 3 into (2) for corresponding value of y

y = - 5(3) + 13 = - 15 + 13 = - 2

solution is (3, - 2 )

Your friend really wants to buy the newest coolest cell phone which will cost him $310 he gets a job detailing cars and suvs and plans to save all the money he earns if he gets paid $60 to detail a car and $85 to detail an suv which of the following inequalities can be used to determine how many of each he must detail in order to earn at least $310

Answers

Answer:

[tex]60c + 85s \geqslant 310[/tex]

Step-by-step explanation:

He needs to earn at least $310 so $60 per car is 60c and $85 per SUV is 85s. So the answer is the third option.

The required inequality:

60x + 85y >= 310

What is inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, a person gets paid $60 to detail a car and $85 to detail an SUV.

Let's assume he needs to detail x number of cars and y number of SUVs to earn at least $310.

Then, the amount earned by detailing x cars and y SUVs can be expressed as:

60x + 85y

According to the problem statement, he wants to earn at least $310, so we can write the inequality:

60x + 85y >= 310

This is the required inequality to determine the number of cars and SUVs he needs to detail in order to earn at least $310.
