Answer:

20

Step-by-step explanation:

vertical angles are equal. meas. of angle a = meas. of angle b

x=5x-80

x+80=5x

80=4x

20=x

Answer:

A = 80

Step-by-step explanation:

If they are vertical angles, they are equal.

5x - 80 = x                      Add 80 to both sides

5x - 80 + 80 = x + 80

5x = x + 80                     Subtract x from both sides

5x - x = x - x + 80

4x = 80                           Divide by 4

4x/4 = 80/4

x = 20

Answer:

-2.8

Step-by-step explanation:

Given that:

Mean, μ = 78

Standard deviation, σ = 5

Omar's score, x = 64

The Zscore of Omar's score :

Zscore = (x - μ) ÷ σ

Zscore = (64 - 78) / 5

Zscore = - 14 / 5

Zscore = - 2.8

Hence, Omar's exam score is - 2.8

Answer:

-2.8 is correct

Answer:

it stays the same

Step-by-step explanation:

if it was -3.3 then it would change to 3.3 but because it is already in the positives it stays a positive plz double chesk if needed tho

Answer:

[tex]3.3[/tex]

Step-by-step explanation:

Absolute value expresses the distance of a number from 0.

For this reason, no matter if the number is negative or positive, the absolute value of it will always be positive.

In this case, it is simply [tex]|3.3|=3.3[/tex].

Answer:

99.33ft^2

Step-by-step explanation:

The surface area of a square pyramid is expressed as;

TSA = a²+2a√a²/4 + h²

Given that

a = 5ft

h = 7ft

Substitute

TSA = 5²+2(5)√5²/4 + 7²

TSA = 25+10√25/4 + 49

TSA = 25 + 10√(221/4)

TSA = 25 + 10(√55.25)

TSA = 25 + 10(7.433)

TSA = 25 +  74.33

TSA = 99.33ft^2

Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2

Answer:5x5=25 fts

4(1/2 x 5ft x7 ft) = 70 fts

Add them up and you get

Answer= 95fts

Answer:

A

Step-by-step explanation:

You convert each fraction to have the same decimal to find the LCD of both denominators

4, 8, 12, 16, 20 and 5, 10, 15, 20 = both of them have 20 in common

You multiply the numerator and denominator by 5 for 2 3/4 and for 5 4/5 you multiply both the numerator and denominator by 4

2 15/20 and 5 16/20

Subtract them and their is your answer

(x + 7)/2 - (x + 4)/2 = (x + 7 - (x + 4)/2 = (x + 7 - x - 4)/2 = 3/2

Answer:

m<X = [tex]126^{o}[/tex]

Step-by-step explanation:

From the given isosceles triangle, we have;

<W and <V as the base angles

So that,

m<W = m<V = 27 (base angles of an isosceles triangle are equal)

Thus,

m<X + m<V + m<W = 180 (sum of angles in a triangle)

m<X + 27 + 27 = 180

m<X + 54 = 180

m<X = 180 - 54

       = 126

m<X = [tex]126^{o}[/tex]

Answer:

4 m = width of the rectangle.

6 m = length of the rectangle

20 m = perimeter of rectangle

3 m = side of the square

Step-by-step explanation:

Let s = length of side of square

s + 1 = width of rectangle

s + 3 = length of rectangle

Area of rectangle = (s + 1)(s + 3)

Area of square = [tex]s^{2}[/tex]

So,  (s + 1)(s + 3) + [tex]s^{2}[/tex] = 33

[tex]s^{2}[/tex] + 4s + 3 + [tex]s^{2}[/tex] = 33

2[tex]s^{2}[/tex] + 4s - 30 = 0

2([tex]s^{2}[/tex] + 2s - 15) = 0

2(s + 5)(s - 3) = 0

s = -5   or   s = 3

Length of a side cannot be negative, so -5 is ignored

3 m = side of the square

4 m = width of the rectangle

6 m = length of the rectangle

2(4) + 2(6) = 8 + 12 = 20 m = perimeter of rectangle

Answer:

y=5x+13

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(3-(-2))/(-2-(-3))

m=(3+2)/(-2+3)

m=5/1

m=5

y-y1=m(x-x1)

y-(-2)=5(x-(-3))

y+2=5(x+3)

y=5x+15-2

y=5x+13

Answer:

y = 5x + 13

Step-by-step explanation:

Slope = delta y/ delta x

(3-(-2))/(-2-(-3))

(5)/(1) = 5

Slope = 5

y = 5x + b

Find the y-intercept through substitution:

(-2,3)

3 = 5(-2) + b

3 = -10 + b

13 = b

Equation:

y = 5x + 13

Answer:

4/45

Step-by-step explanation:

The sum of angles in a triangle is 360 degrees

If the angle measures 32 degrees, the fraction can be represent as 32/360

32/360 has to be converted to its simplest form. To this divide both the numerator and the denominator by 8. This gives 4/45

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.

Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.

Solving that equation will give you b=-7

That means the y-intercept is -7.

The equation would then be y=4x-7

Answer: B

Step-by-step explanation:

Applying limits, it is found that the end behavior of the graph is:

B. As [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex], and as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex].

The function is:

[tex]h(x) = -2x^5 + 8x^4 - 2x^2 + 15[/tex]

To find the end behavior, we apply the limits as x goes to infinity, in which just the term with the highest exponent is considered, hence:

[tex]\lim_{x \rightarrow -\infty} h(x) = \lim_{x \rightarrow -\infty} -2x^{5} = -2(-\infty)^5 = -2(-\infty) = \infty[/tex]

Then, as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex]

[tex]\lim_{x \rightarrow \infty} h(x) = \lim_{x \rightarrow \infty} -2x^{5} = -2(\infty)^5 = -2(\infty) = -\infty[/tex]

Then, as [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex]

Hence, option B is correct.

Answer:

  q = 9

Step-by-step explanation:

The angle bisector divides the triangle sides proportionally.

  q/36 = (16 -q)/28

  7q = 9(16 -q) . . . . . . multiply both sides by 252 (the LCM of 28 and 36)

  16q = 16(9) . . . . . . . . add 9q to both sides

  q = 9 . . . . . . . . . . . . . divide by 16

Additional comment

We are given the sum of the segment lengths on the far left side. The proportion is the same for the sum of sides as it is for individual sides.

  (q/36) = 16/(36+28)

  q/36 = 16/64 = 1/4

  q = 36/4 = 9
