Answer:

Step-by-step explanation:

1. 30 degrees (vertical angles)

2. 60 degrees (complementary angles)

3. 150 degrees (supplementary angles and vertical angles)

4. 90 degrees (complementary angles)

Answer:

Step-by-step explanation:

Answer:

B is not correct. rational numbers can be negative

Answer:

The first one

Step-by-step explanation: the ABC triangle has a 25-degree angle and a 90-degree angle as you can see by the marks. The first triangle has a 25-degree angle and a 90-degree angle as you can see by the marks. The second one does have a 90-degree angle but it's a different shape and has no 25-degree angle. The third one has both angles 25 and 90 but if you look close it's a different shape. The last one does not have a 90-degree angle but it does have a 25-degree angle and it's a different shape.

So it would be the first option.

Answer:

the answers is B, 3,4,5

Step-by-step explanation:

Answer:

Step-by-step explanation:

hello :

cos²θ +sin²θ = 1 and cosθ =4/5

(4/5)² + sin²θ = 1 so : sin²θ = 1 - 16/25

sin²θ = 9/25 = (3/5)²

sinθ = 3/5 or sinθ = - 3/5 because : (3/5)²= (- 3/5)²= 9/25

Answer:

y = -1/2x + 2

Step-by-step explanation:

A perpendicular line will have a opposite reciprocal slope.

Since the line's slope is 2, the perpendicular line will have a slope of -1/2

Plug in the slope and given point into y = mx + b, and solve for b

y = mx + b

3 = -1/2(-2) + b

3 = 1 + b

2 = b

Plug in the slope and b into y = mx + b

y = -1/2x + 2

So, the equation is y = -1/2x + 2

Answer: The coordinates of the triangle JKL are (1,2),(4,2) and (3,5)

We need to determine the coordinates of the triangle J'K'L' rotated 360° clockwise with the origin.

Coordinates of the triangle J'K'L':

The rule to rotate the triangle 360° clockwise with the origin is given by

(x,y) => (x,y)

The coordinates of the point J' is given by

(1,2) => (1,2)

The coordinates of the point K' is given by

(4,2) => (4,2)

The coordinates of the point L' is given by

(3,5) => (3,5)

Therefore, the coordinates of the triangle J'K'L' are (1,2), (4,2) and (3,5)

Answer:

x = 10

y = 20

Step-by-step explanation:

7x + 90 + 20 = 180

7x = 70

x = 10

5x + 2y = 90

50 + 2y = 90

2y = 40

y = 20

Answer:

x = 9.4868

Step-by-step explanation:

For this problem we can use the Pythagorean Theorem

Pythagorean theorem = [tex]a^2+b^2=c^2[/tex]

IN THIS CASE C = X

A and B are the side and base lengths of a right triangle.

C is the Hypotenuse side.

[tex]9^2+3^2=c^2[/tex]

Solve...

81 + 9 = [tex]c^2[/tex]

90 =[tex]c^2[/tex]

[tex]\sqrt{90}[/tex] = c

c = 9.4868

Answer:

75%

Step-by-step explanation:

The computation of the percent of the professional professors there are tenured is shown below;

Given that

academic professors A = 60%

professors  tenured P = 70%

professors at Paracelsus University = 90%

Based on the above information

As we know that 90% of the professors could be academic professors or tenured or both

so  here we can say that the percent of academic professors  is

= 60 + 70 - 90

= 40

Therefore professors  tenured will be

= 70 - 40

= 30

Now the percentage of professional professor that is tenured is

= 30 ÷ 40 × 100

= 75%

Answer:

5,7%

Step-by-step explanation:

190270 is 100%

1% is 1902,7

10770/1902,7 = 5,66

Answer:

Step-by-step explanation:

The area for the sector of a circle is

[tex]A_s=\frac{theta}{360}*\pi r^2[/tex]  where theta is the measure of the central angle. We have some given values to fill in:

Area is 64π and the central angle is 90°, so all we have left to find is the radius. Filling into the equation:

[tex]64\pi =\frac{90}{360}*\pi r^2[/tex]

Let's get that solved for r-squared first:

[tex]\frac{360(64\pi )}{90\pi } =r^2[/tex]

Doing all the math on that gives us:

[tex]256=r^2[/tex]

Take the square root of both sides and get that r = ±16. BUT we know that lengths cannot be negative, so we disregard the -16 and say that the radius is 16 inches.

8 girls are there in Mrs. Sanchez' class.

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

Based on the given conditions, formulate

2 girls ⇒ 3 boys

X girls ⇒ 12 boys

3X = 12 × 2

⇒ 3X = 24

⇒ X = [tex]\frac{24}{3}[/tex]

⇒ X = 8

Hence, 8 girls are there in Mrs. Sanchez' class.

4/3 x 5/8 is correct

Step-by-step explanation:

Answer: C 7/10 * 5/8

Step-by-step explanation:

4/3 * 5/8 = 20 / 24 = 5 / 6

3/2 * 5/8 = 15 / 16

7/10 * 5/8 = 35/80 = 7 / 16

9/7 * 5/8 = 45 / 56

5/8  = 10/16

7/16 < 10/16

Answer:

H  mean of data for store 1 is greater than mean for store 2

Step-by-step explanation:

mode for store 1 = 3

mode for store 2 = 2

range for store 1 = 6

range for store 2 = 6

mean for store 1 = 3.3125

mean for store 2 = 2.588

median for store 1 = 3

median for store 2 = 2

Answer:

-6

Step-by-step explanation:

Let the number be 'x'

Sum of a number and one = x + 1

Sum of a number and one is doubled = 2*(x +1) = 2*x + 2*1 = 2x + 2

Four less than the number = x - 4

2x + 2 = x - 4

Subtract 'x' from both sides

2x - x + 2 = x - x - 4

x + 2 = -4

No, subtract 2 form both sides

x + 2 -2 = - 4 - 2

x = -6
