Answer:

The number of students in each van = 14

The number of students in each bus = 43

Step-by-step explanation:

Let the number of students that can fill a van be v.

Let the number of students that can fill a bus be b.

The senior class at High School A rented and filled 13 vans and 9 buses with 569 students.

13 vans will have (13v) students

9 buses will have (9b) students

13v + 9b = 569

High School B rented and filled 14 vans and 3 buses with 325 students

14 vans will have (14v) students.

3 buses will have (3b) students.

14v + 3b = 325

Combining these two simultaneous equations

13v + 9b = 569

14v + 3b = 325

Solving simultaneously,

v = 14 students.

b = 43 students.

Hope this Helps!!!

Answer:

P = 3

Q = -4

R = 22

Step-by-step explanation:

Expand both sides and compare coefficients.

5Px^2 -PQx +10x -2Q = 15x^2 + Rx +8

Compare coefficients of x^2

5P = 15  => P = 3

Compare constant terms

-2Q = 8

Q = -4

Compare coefficients of x

-PQ + 10 = R

-(3)(-4) + 10 = R

R = 10 + 12 =22

Answer: z score is -19

Work Shown:

x = 22 is the raw score

mu = 60 is the mean

sigma = 2 is the standard deviation

z = (x-mu)/sigma = formula to find z scores

z = (22 - 60)/2

z = -38/2

z = -19

The z score of -19 means we are 19 standard deviations below the mean. Anything beyond 3 standard deviations is often considered unusual/rare as most of the data in the normal distribution is within 3 standard deviations (approximately 99.7% of the distribution)

Answer: A

Step-by-step explanation:

Divide each total by 5 to get 5, 200, 20, 2.50.  $5 per value meal is the most fair price.

Hope it helps <3

If the total is 25$, then each value meal would equal 25/5 = 5$, which is reasonable. so option A is correct.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

A. If the total is 25$, then each value meal would equal 25/5 = 5$, which is reasonable.

B. If the total is $1000, then each meal would equal 1000/5 = $200, which is not reasonable

C. If the total is $100, then each meal would equal 100/5 = $20, which is not a reasonable price for a value meal

D. If the total is $10, then each meal would equal 10/5 = $2 which is not a reasonable price for a value meal.

Hence, If the total is 25$, then each value meal would equal 25/5 = 5$, which is reasonable. so option A is correct.

Answer:

  43.96 in^2

Step-by-step explanation:

The net shows the areas of the parts of the cone, so you simply need to add them up to get the total surface area.

  31.4 in^2 +12.56 in^2 = 43.96 in^2

Answer:

43.96 in.2.

Step-by-step explanation:

The surface area of a cone is the triangular shape and its circular base.

In this case, the top of the cone is 31.4 inches squared in area, and the circular base is 12.56 inches squared.

So, the surface area of the cone is 31.4 + 12.56 = 43.96 inches squared.

Answer:

8.5 units

Step-by-step explanation:

x is the adjacent side, the side that's 19 units is the opposite side.

Given the adj and the opp sides, use tangent.

tanθ= opp/adj

tan 66°= 19/ x

x(tan66°)= 19

x= 19/(tan 66°)

x= 8.5 units (nearest tenth)

It's totally false to say that the student has special needs or it's totally false to say the student doesn't belong in the classroom.

Answer:

It is not correct.

Step-by-step explanation:

If you plug 4 in for x, you get -2*4+5=13. This simplifies to: -8+5=13. This is an untrue statement since -8+5 is actually -3, not 13.

Hope this is helpful! :)

Answer:

undefined

Step-by-step explanation:

So with the following equation,

-2x + 5 = 13

we plug in 4 for x

-2(4) + 5 = 13

-2 * 4 = -8

-8 + 5 = 13

-8 + 5

-3 = 13

-3 is not 13 so it is undefined

Thus,

the answer is undefined.

Answer:

XY = 24 units

Step-by-step explanation:

First of all, we need to some construction here.

Let us draw a line parallel to XY from point P towards OX, which cuts OX at point Q.

Please refer to the attached figure.

Now, Let us consider triangle OQP which is a right angled triangle, with

Hypotenuse, OP = 26 units

Height, OQ = OX - PY = 16  - 6 = 10 units

Base, PQ = ?

We can use pythagorean theorem here to find the value of PQ.

According to pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OP^{2} = PQ^{2} + OQ^{2}\\\Rightarrow 26^{2} = OQ^{2}+10^{2} \\\Rightarrow PQ^{2} = 26^{2}-10^{2} \\\Rightarrow PQ^{2} = 676-100 \\\Rightarrow PQ^{2} = 576\\\Rightarrow PQ= 24\ units[/tex]

Now, we can see that side PQ is equal to side XY.

[tex]\therefore[/tex] XY = 24 units is the answer.

Answer:

Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles are 12. So, we then know that a = 20.

(Root 15^2-9^2=12) (Root 12^2+16^2=20)

Another way is using the whole triangle. The step above used two triangles. The two triangles together makes a big right triangle, so we can again use the Pythagorean theorem. So, the answer again is 20.

(Root 25^2-15^2=20)

Step-by-step explanation:

Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles is 12. So, we then know that a = 20.

We have to find the value of ‘a’ using two different ways.

By the Pythagorean theorem,

By cross multiplication,

16(25) = a2

a2 = 400

Taking square root,

a = 20

Therefore, the length of the other side a = 20.

You can calculate the mean value by adding up the numbers and then dividing the result by the number of numbers. For instance, to find the mean value of 4, 1, 3, and 8, first, add up the numbers: 4+1+3+8=16 4 + 1 + 3 + 8 = 16.
