Answer:

Number of 8th Graders = 360 - X  

As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from 8th grade.

As we know:

Total number of students on the A honor roll = 360

We are asked to calculate, number of students from 8th grade on the A honor  roll.

So, let's assume that "X" represents all the students who are on the A honor roll except 8th grade.

Mathematical Expression:

Number of 8th Graders = Total number of students on the A honor roll - X

Number of 8th Graders = 360 - X

So, if you know the value of X, you can easily calculate the number of students which are from 8th grade on the A honor roll.

16. >

Step-by-step explanation:

13. √15 - 4 = -0.12 and √15 - 7 = -3.12

14. 2√18 = 8.4 and 2√21 = 9.16

15. -^3√30 = -3.1

16. √8 + 1 = 3.8 and √17 - 2 = 2.1

Answer:

40%

Step-by-step explanation:

The first step is to add 18 girls + 12 boys, which gives you the total number of people on the swim team, 30.

Next, you divide the 12 boys by the total swim team members, so:

[tex]\frac{12}{30}[/tex] = 0.4

Then, you multiply 0.4 by 100 to get the percentage:

0.4 × 100 = 40

Therefore, the swim team is made up of 40% boys, and 60% girls.

Answer:

40%

Step-by-step explanation:

30 total kids

12/30 as a decimal is 0.4

to make a decimal into a percent you move the decimal point 2 times to the right

that would be 40

then add the percent to make 40%

Answer:

[tex] \frac{14}{4} [/tex]

simplified [tex] \frac{7}{2} [/tex]

Step-by-step explanation:

To turn a mixed number into a fraction :

[tex]3\frac{ + 2}{ \times 4} [/tex]

3 x 4 =12 +2 =14 that will be your numerator (top number on a fraction)

and 4 will be your demoninator (bottom number)

Answer:

No solutions

Step-by-step explanation:

If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. ... When the lines are parallel, there are no solutions, and sometimes the two equations will graph as the same line, in which case we have an infinite number of solutions.

Hope this helped! Have a nice day! Plz mark as brainliest!!!

Step-by-step explanation:

it is the only one that has angles that are right next to eachother!

Answer/Step-by-step explanation:

✔️Diagonals of a rhombus bisect each other at 90°.

Therefore,

m<1 = 90°

✔️Since opposite sides of a parallelogram are parallel, therefore:

m<2 = 53° (alternate angles)

✔️Diagonals bisect each angle of a parallelogram, therefore,

m<3 = m<2

m<3 = 53°

✔️m<4 + m<3 + 90° = 180°(sum of triangle)

m<4 + 53° + 90° = 180° (substitute)

m<4 = 180 - 143

m<4 = 37°

Answer:

200 minutes

Step-by-step explanation:

Let us assume the number of minutes be x

Now the two equations are

$8 + 0.12x = 0

And, $18 + 0.7x = 0

In the case when the cost of the two plans is equal

So

$8 + 0.12x  = $18 + 0.7x

$8 - $18 = 0.7x - 0.12x

-$10 = -0.05x

x = 200 minutes

the answer will be 3/5 hope it helps

Answer:

3/5

Step-by-step explanation:

It is like addition, 1 + 1 + 1 which equals to 3.

Step-by-step explanation:

In order to find the slope, we must know the formula needed.

[tex]\frac{y2}{x2} -\frac{y1}{x1} =m[/tex]

Using 2 given points, we can subtract both and receive our final answer.

Points that are provided:

Substitute the given points into the formula format.

Then, solve.

[tex]\frac{3}{4} -\frac{-1}{1} =\frac{4}{3}[/tex]

m = 4/3

The slope is positive. Meaning that the slope is increasing for the value of y.

Answer:

557.8

Step-by-step explanation:

Because the semi circle on the top and the semi circle on the bottom form a circle with an area of 314.16.

The semicirlces on either side form a circle with an area of 66.48.

Then the rectangle in the middle has an area of 9 times 20 which is 180.

If you add those areas together you get the total area which is about 557.8

I hope this is helpful :)
