Answer: 83.56

Step-by-step explanation:

To calculate the mean score for all ninth graders in the city, we multiply the mean score test for each school by the number of months grade students and then add all together and divide by the total ninth grade students. This is solved below.

Mean = [(79 × 285) + (94 × 336) + (72 × 191)]/285+336+191

= (22515+31584+13752)/812

= 67851/812

= 83.56

Step-by-step explanation:

Bob has less than 5 cats.

Therefore he does not have more cats.

With this information you a, b, c, and f.

And since he also can't have an equal amount of cats, that gives you a, and f.

But it can't be less than or equal to stated earlier.

Therefore you get answer choice a!

Answer:

A

Step-by-step explanation:

Answer:

Step-by-step explanation:

find:

1) x

2) y

3) z

solve for x:

1) opposite angle are equal.

x = 124°

solve for y:

2) inside angle of a triangle = 180

  180 = 53 + 39 + y

  180 - 53 - 39 = y

  y = 88°

solve for z:

3)  z + y = 180

    substitute y = 88

   z + 88 = 180

   z = 180 - 88

   z = 92°

Answer:

the answer is B.

Step-by-step explanation:

since the M is the middle point of the angles AB and DC.

we just add the M in the middle.

also i did the test and got it right, soooo im 100% sure its B

This is about understanding vertical angles theorem.

Option B is Correct

The two opposite angles they form are; ∠AMB and ∠DMC.

∠AMB is congruent to ∠DMC.

The congruency symbol is ≅.

Thus; ∠AMB ≅ ∠DMC.

Answer:

Step-by-step explanation:

From the options presented, driver B has the fastest typical race time because he recorded the smallest time taken to complete an individual race.

Also from the standard deviation given (3.96) for driver B, it shows that the individual time spread from the standard deviation is minimal and that the driver maintained a fairly consistent time of race throughout the racing period.

Step-by-step explanation:

Given that :

Objective is to compete in a 5km road race ;

Reduction in race tone per month = 15 seconds

Rqce comes up in 3 months

Total change in race time he hopes to achieve :

1. What integer represents the change in race time Riley wants to achieve each month ; 15 seconds

2. What integer represents the number of months she will train?

She will train for 3 months ; 3 months

Write a multiplication expression that can be used to find the total change in time.

Change in race time * number of month she will train

15 seconds * 3 months = 45 seconds

Let initial race time = (t)

t - 15(month in which race comes up).

t - (15-3) = t - 45

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

6a)

[tex]62+67=129\\m<1=129[/tex]

6b)

[tex]180-152= 28\\28+115=143\\180-143=37\\m<1=37[/tex]

Answer:

Step-by-step explanation:

6a. inside the triangle:

      x + 62 + 67 = 180

       x + 129 = 180

       x = 51

For <1: m<1 + 51 = 180

           m<1  = 129

6b. for next to the exterior:

       x + 152 = 180

       x = 28

Inside the triangle:

 m<1 = m<1 + 28 + 115 = 180

           m<1 + 143 = 180

           m<1 = 37

Answer:

[tex]\displaystyle b=\frac{2A}{h}[/tex]

Step-by-step explanation:

Solving an equation

To solve en equation for a given variable, the general method is to isolate the variable by performing inverse operations.

Let's focus on the equation:

[tex]\displaystyle A=\frac{1}{2}bh[/tex]

First, let's flip both sides of the equation:

[tex]\displaystyle \frac{1}{2}bh=A[/tex]

Multiply both sides by 2 since it's dividing the required variable:

[tex]\displaystyle \not 2\cdot \frac{1}{\not 2}bh=2*A[/tex]

Simplifying

[tex]bh=2A[/tex]

Dividing by h:

[tex]\displaystyle \frac{b\not h}{\not h}=\frac{2A}{h}[/tex]

Simplifying:

[tex]\boxed{\displaystyle b=\frac{2A}{h}}[/tex]

Answer:

7(xy)^3-36y^3/4x^2

y=4x+7

X=4y+7

X-7=4y

X-7/4=y

F-1(x)=x-7/4

The inverse of the function is y = (x-7)/4 , the steps are correctly ordered.

An Inverse function is found when the variables x and y are interchanged in the f(x,y) function and then the equation is solved for y.

The function is

f(x)= 4x+7

y = 4x+7-------- Step 7

y-7 = 4x--------Step 2

x = 4y +7------ Step 3

x - 7 = 4y------- Step 6

(x-7)/4 = y------- Step 4

f⁻¹ (x) = (x-7)/4------- Step 5

Steps 1 and 8 are not part of finding Inverse of the function.

Therefore, the inverse of the function is y = (x-7)/4 , the steps are correctly ordered.

Answer:

The slope of the line is -2

Step-by-step explanation:

The rule of the slope of a line is:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]  , where

[tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are two points on the line

Let us find the slope using the rule above

∵ The line passes through points (3, -7) and (-1 , 1)

∴ [tex]x_{1}[/tex] = 3 and  [tex]x_{2}[/tex] = -1

∴ [tex]y_{1}[/tex] = -7 and  [tex]y_{2}[/tex] = 1

Substitute these values in the rule above to find m

∴ [tex]m=\frac{1--7}{-1-3}=\frac{1+7}{-4}=\frac{8}{-4}=-2[/tex]

∴ The slope of the line that passes through the given points is -2
