Answer:

  B.  66°

Step-by-step explanation:

The remote exterior angle (z) is the sum of the measures of the interior angles (x, y).

  x + y = z

  (5n -19) +(n +7) = (144 -6n)

  12n = 156 . . . . . . . . . . . . . . . . . add 6n+12

  n = 13 . . . . . . . . . . . . . . divide by 12

Then the measure of the remote exterior angle is ...

  m∠z = (144 -6(13))° = (144 -78)°

  m∠z = 66°

__

x = 46°

y = 20°

Answer:

0.04

Step-by-step explanation:

For a density curve, total area = 1

Probability lies in between 0 and 1

The Area of triangle :

Area = 1/2 base * height

Base = 0 - 50 = 50

Area = 1

Hence,

1 = 1/2 * 50 * h

1 = 50h / 2

2 = 50h

h = 2 / 50

h = 0.04

Answer:

The family has 1/4 of the strawberries left to snack on, or 31 left to snack on.

Step-by-step explanation:

Since they gave away 1/4 of the strawberries to their neighbor, and the others were used in a pie, that means that 1/4 of the strawberries remain. You do 124/4 in which 1/4 of that is 31, since 31x4 is equal to 124.

Answer: 240 feet

Step-by-step explanation:

What you could do is find the area of the whole thing. 12x25 is 300. Then, you can find the area of the white part, which is 60, because you multiply 12x5. then, you would subtract 60 to 300, which would get you to 240 feet.

Answer:

The answer is : 240cm² for the shaded part

The unshaded part is = 60cm²

The whole rectangle = 300cm²

Step-by-step explanation:

Area is = WL

W = width (while the) L= length

The Area = 25 × 12 = 300

The area of the full rectangle is = 300

The unshaded part is = 5 × 12 = 60

So the shaded part is = 300 - 60 = 240cm²

[tex]so \: the \: answer \: is \: = 240cm^{2} [/tex]

Answer:

A reflection about y=x

Step-by-step explanation:

The 4 transformations are

Let eliminate which ones won't work.

A translation wouldn't flip the triangle in a different direction after translating it so we won't translate it.

A dilation changes the length for the triangle but the triangles are congruent so we won't dilate it.

A rotation about the orgin wouldn't work nor a specific point so a rotation isnt going to work.

A reflection will work so what will we reflect about.

A reflection makes a reflected point equidistant from the line of reflection and their original point is equidistant from line of reflection.

So let find the midpoint of all the points and find a line where all of them are on.

The midpoint respectively are

Let find the line that includes both these points.

[tex] \frac{6 - 4}{6 - 4} = \frac{2}{2} = 1[/tex]

Step-by-step explanation:

2x + 6 = 7x - 14

2x + 6 - 2x + 14 = 7x - 14 - 2x + 14 ----> To put the variables on one side and the numbers on the other side

20 = 5x --> Simplifying

x = 20/5 --> Flipping the equation and then dividing 5 on both sides

Answer:

c. A number relatively close to 100.

Step-by-step explanation:

Given

[tex]Range: 0 \to 1[/tex]

[tex]N =1000[/tex] --- i.e. the cells

Required

Number of cells that contains less than or equal 0.2

Less than or equal 0.2 means that the numbers are approximately 20% of the whole distribution

So, to calculate the number (n) of these cells, we do the following computation

[tex]n = 20\% * N[/tex]

[tex]n = 20\% * 1000[/tex]

[tex]n = 200[/tex]

200 is closer to 100 than 500. Hence, (c) is correct

Answer:

A = $174,742.21

A = P + I where

P (principal) = $100,000.00

I (interest) = $74,742.21

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 100,000.00(1 + 0.08/12)(12)(7)

A = 100,000.00(1 + 0.006666667)(84)

A = $174,742.21

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $100,000.00 at a rate of 8% per year compounded 12 times per year over 7 years is $174,742.21.

[tex]volume \: of \: the \: rectriangular \: prism = ( \frac{1}{2} \times base \times 4) \times 2 \\ 4 \times base = 40 \\ base = 10m[/tex]

Answer:

length = 15 meters

Step-by-step explanation:

Volume of a pyramid is:

V = l*w (h/3)

We know that; Volume is 40, Width is 2, and Height is 4, therefore;

40 = l*2 (4/3)

40 = 2l (4/3)

(3/4) * 40 = 2L

30 = 2L

30/2 = L

15 = L

therefore the length = 15 meters

Hope this helps!

Good Luck!

Please mark me bralinest if you can :)

Answer:

Vertical

Step-by-step explanation:

<AGB and <EGD are vertical angles because they are vertically opposite from each other since they were created from two lines crossing.

-You know that they aren't adjacent because they aren't next to each other and don't share a side or a vertex.

-They can't be supplementary because they don't add up to 180 degrees

-They can't be complementary because they don't make up 90 degrees

The value of a is 9.

A factor of polynomial P(x) is any polynomial which divides evenly into P(x).

For finding the factor of a polynomial we will perform following steps:

According to the given question.

We have a cubic polynomial [tex]x^{3} -4x^{2} +ax -2a[/tex]

Also, x - 3a is a factor of the given polynomial.

⇒ [tex]x - 3 = 0[/tex]

⇒[tex]x = 3[/tex]

⇒ 3 is the one solution of the given cubic polynomial.

If 3 is the one solution of the cubic polynomial then it must satisfy the equation (i).

So, substitute the value of x in the given polynomial.

[tex](3)^{3} -4(3)^{2} + a (3) - 2a = 0[/tex]

⇒[tex]27 -4(3)^{2} +a(3) -2a=0[/tex]

⇒[tex]27 - 36 + 3a - 2a= 0[/tex]

⇒[tex]-9 + a = 0[/tex]

⇒ [tex]a = 9[/tex]

Therefore, the value of a is 9.
