160.13

Step-by-step explanation:

you would divide 6.75 by 100 then multiple that to 150 the you would take that answer and add it to 150

Answer:294

Step-by-step explanation: you’re trying to find the surface area of the cube to find out how much material Daria needs. To do so find the area of 1 face of the cube (which is a square). The problem gives us 1 side of the square as 7cm. A square has the same length for its 4 sides, so to find the area of that 1 face do 7 x 7=49. The question also gives the hint that a cube has 6 faces so you would multiply the 49 by 6 to get the total surface area of the cube. 49 x 6=294.

Not sure if this is right but hope it helps.

Answer:

[tex]\angle NPM[/tex]

Step-by-step explanation:

Given

Circle of center P

Polygon JKLMN

Required

The central angle of JKLMN

From the question, we have that: the polygon and the circle have the same center (P).

This means that any central angle must pass through P

By this, PMN and NJK are incorrect

QPK divides the polygon and point Q is not on the vertex of the polygon.

By this, QPK is also incorrect

The final option NPM is correct, because P is at the center and points N and M are at the vertices of the polygon

Answer:

x = 7/6

Step-by-step explanation:

6x+5 = 12

Subtract 5 from each side

6x+5-5 = 12-5

6x = 7

Divide each side by 6

6x/6 = 7/6

x = 7/6

Answer:

x=7/6

Step-by-step explanation:

6x+5 = 12

subract 5 from both sides

6x = 7

divide by 6 on both sides

x=7/6

Answer:

x = -4/7

Step-by-step explanation:

-5/2x + 1 = x + 3

-7/2x = 2

(-2/7)-7/2x = 2(-2/7)

x = -4/7

Hi there!

Answer:

3

Step-by-step explanation:

Prime factorize 42 and 3 and you'll eventually get 3 as your answer.

Answer:

3

Step-by-step explanation:

Since you are looking for the greatest common factor, 3 cant have many factors other than itself. So it would be 3, when simplified its similar to 42/3 and 3/3 where it would be 14 and 1.

Answer:

Step-by-step explanation:

- Since y = -1, we will substitute the y variable in the equation for -1.

 -1 = -5/2x + 4

- Take away 4 from both sides in order to find out what x equals so we can substitute it.

 5 = -5/2x

- turn it into a positive by multiplying each side by -1.

 -1(-5 = -5/2x) =

 5 = 5/2x

- Divide each side by 5.

 1 = 1/2x

- Multiple both sides by 2.

2 = x

- Substitute the variables.

x = 2

y = -1

-1 = -5/2(2) + 4

Answer:

I believe it would be (c)

Answer:

A

Step-by-step explanation:

Answer:

6a + (6 x 3) = 60

or

6a + 18 = 60

Step-by-step explanation:

You have 6 students who are assigned an unknown amount of problems. We can write it as 6x. Then each is given 3 more problems, so now we have 6x + (6 x 3). We also know that in all they have 60 problems.

Therefore, the equation is:

6x + 18 = 60

Then just solve

6x + 18 = 60

     - 18   -18

6x = 42

x = 7

Which statement is supported by the information in his graphs?

A

It can be inferred that on the days that students are offered pizza and salad, 70% of students are pleased with the offerings.

B

It can be inferred that about the same number of students get a salad as the number of students that like cheeseburgers and tacos combined.

C

It can be inferred that pizza and chicken nuggets should be the only meals offered in the cafeteria to please the most students each day.

D

It can be inferred that if the lunchroom offered cheeseburgers and tacos on the same day, every student would get a tray that day.

Answer:

It can be inferred that pizza and chicken nuggets should be the only meals offered in the cafeteria to please the most students each day.

Step-by-step explanation:

From barchart, we can observe that ; the both pizza and chicken nugget have the highest number of 7th grade students who prefer them. Hence, with these numbers, most students will be pleased if these are the food options served each day.

Answer:

x = 0.69 is what i got

Step-by-step explanation:

Answer:

BC≈1.71

Step-by-step explanation:

The cosine of an angle is the adjacent side relative to that angle divided by the hypotenuse.

cos(70)=BC/5

BC=cos(70)*5≈1.71

Answer:

dependent & changes by a constant rate

Step-by-step explanation:

Answer:

Part A: one solution:

Part B: x = 3, y = 4.

1) Part A: how many solutions does the pair of equations for lines A and B have?

The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.

In this case, there are two straight lines, which intersect in one and only one point.

Hence, the system has one solution.

2) Part B: what is the solution to the equations of lines A and B?

The solution is the pair of coordinates of the intersection point. It is (3, 4).

Therefore, the solution is x = 3, y = 4.

Answer:

I believe the answer is b.73.7

Answer:

73.7

Step-by-step explanation:

Answer:

Amanda > Todd > Derrick

Step-by-step explanation:

Amanda's IQR- 3.5

Derrick's IQR- 2

Todd's IQR- 3

The solution is, ordering the IQR in descending order :

Emma, Sally, Olivia

The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set. Whereas the range gives you the spread of the whole data set, the interquartile range gives you the range of the middle half of a data set.

here, we have,

Writing out the points obtained from the dot plot, and applying the relevant formula, the Interquartile range of each dot plot is given below ;

Writing out each score on the dot plot to calculate the statistical values :

Emma's Scores:

6 , 7 , 8 , 8 , 9 , 9 , 9 , 10 , 10 , 11 , 11 , 11 , 11 , 11 , 12 , 13 , 13 , 13 , 13 , 14

Q1 = 1/4(n+1)th term

Q1 = (5th + 6th) terms

Q1 = (9 + 9) / 2 = 9

Q3 = 3/4(n+)th term

Q3 = (12 + 13) ÷ 2 = 12.5

IQR = Q3 - Q1

IQR = 12.5 - 9 = 3.5

Sally's Scores:

6 , 6 , 6 , 7 , 7 , 8 , 8 , 8 , 9 , 9 , 10 , 10 , 10 , 10 , 10 , 10 , 11 , 11 , 12 , 12 , 14

Q1 = 1/4(n+1)th term

Q1 = (7 + 8) ÷ 2 = 7.5

Q3 = 3/4(n+1)th term

Q3 = (10 + 11) ÷ 2 = 10.5

IQR = Q3 - Q1

IQR = 10.5 - 7.5 = 3

Olivia's Scores:

6 , 6 , 7 , 7 , 7 , 8 , 8 , 8 , 8 , 9 , 9 , 9 , 9 , 9 , 10 , 10 , 12 , 12 , 13 , 14

Q1 = 1/4(n+1)th term

Q1 = (7 + 8) ÷ 2 = 7.5

Q3 = 1/4(n+1)th term

Q3 = (10 + 10) ÷ 2 = 10

IQR = Q3 - Q1

IQR = 10 - 7.5 = 2.5

Therefore, ordering the IQR in descending order :
