Answer:

Michelle must get an 80 on her next test to keep her average score.

Step-by-step explanation:

Since Michelle got an average score of 80 on two tests, to determine what score she must get on the third test so that her average score for the three tests is the same as the average score for the first two tests, the following calculation must be performed:

X / 2 = 80

X = 80 x 2

X = 160

X x 3 = 80 x 3

X x 3 = 240

X = 240/3

x = 80

So, Michelle must get an 80 on her next test to keep her average score.

Answer:120 Degrees

Step-by-step explanation:

Angle M and N add up to 180 degrees so,

180= 11x-40 (Since 3x+8x would be 11x)

220=11x (Add 40 to both sides)

X=20 (divided 220 by 11)

Answer: D. -7x-5y=-48

Step-by-step explanation:

The slope of AB is [tex]\frac{-1-4}{-3-4}=\frac{5}{7}[/tex]. Since perpendicular lines have slopes that are negative reciprocals, the slope of BC is -7/5.

Substituting into point-slope form,

[tex]y-4=-\frac{7}{5}(x-4)\\\\5y-20=-7(x-4)\\\\5y-20=-7x+28\\\\\boxed{-7x-5y=-48}[/tex]

Answer:

1 = -48

2 = 9

3 = -6

4 = - 4

Step-by-step explanation:

Hello there!

For each problem we are going to want to plug in the value of x (which is given) and find the total value of the expression

For #1

8(-4) + 4(-4)

8 * - 4 = -32

4*-4=-16

-32+(-16)=-48

So the answer to #1 is -48

For #2

9(3)-18

9*3=27

27-18=9

so the answer to #2 is 9

For #3

-2(8)+10

-2*8=-16

-16+10=-6

so the answer to #3 is -6

For  #4

5(-3)+11

5*-3=-15

-15+11=-4

So the answer to #4 is -4

Answer:

[tex]y = 2x + 9[/tex]

Step-by-step explanation:

Step 1: I have to compare the equation given to the equation of a straight line

From the question, we have:

[tex]y = 2x - 4 \\ y = mx + c[/tex]

hence m = 2 and c = -4

So, the choice B: y = 2x + 9

Gives : m = 2 and c = 9

Hence since m is the same that is (= 2) and c is different, hence the equation has not solution then.

So, the answer is choice B

Answer:

this figure is trapezium.

area of trapezium =1/2×(a+b)h

area of trapezium =1/2×(7+24)×24

area pf trapezium =1/2×31×24

area of trapezium =372unit²

Answer:

12.6 cm

Step-by-step explanation:

Rewrite the fractions to have a common denominator:

1/3 = 10/30

4/6 = 20/30

1/5 = 6/30

Now compare the numerators and list from smallest to largest:

6/30, 10/30, 20/30

The order would be:

1/5, 1/3, 4/6

Answer:

1/5, 1/3, 4/6

Step-by-step explanation:

The bigger the fraction denominator the smaller is.

1. 1143.36.

2. Withdrawal

3. Deposit

4.C

Answer:

[tex]r=20.1[/tex]

Step-by-step explanation

[tex]C=\pi d[/tex]

Green car circumfrence = 126 feet

Plug in numbers

[tex]126=3.14d[/tex]

Divide both sides by 3.14

[tex]\frac{126}{3.14} = 40.12...[/tex]

Divide diameter by 2 to find radius

[tex]\frac{40.1}{2} = 20.05[/tex]

round up to [tex]20.1[/tex]

Answer:

b. Tan A = 5/12

Step-by-step explanation:

Recall: SOHCAHTOA.

Since the trigonometric function we are to find is Tan A, we would use TOA, which is:

Tan θ = Opp/Adj

θ = A

Opp = 20

Adj = 48

Thus:

Tan A = 20/48

Simplify the fraction

Tan A = 5/12

Answer:

Radius and diameter are not part of a pyramid

Answer:

x= 29°

y= 73°

z= 102°

Step-by-step explanation:

x is on the opposite side of the 29° which means it is equal to 29°

In order to find y we can add 29°+78° and subtract it from 180° since all triangles add up to 180°.

This makes y = 73°

In order to find z, we can subtract 78 from 180 since all straight lines are 180 degrees.

This makes z = 102°
