Answer 1

Answer:

D) 121 degrees

Step-by-step explanation:

A linear pair is a pair of angles that share a side and a base. In other words, they are the two angles created along one line when two lines intersect. Linear pairs are always supplementary.

In this case, since supplementary angles add up to 180 degrees, we set up an equation:

<A+<B=180

(6x-19)+(11x-22)=180

17x-41=180

17x=221

x=13

Now we plug in x=13 for angle B:

11x-22

11(13)-22

143-22

121

Therefore, the measure of angle B is 121 degrees

A recipe requires 1 2/3 cups of sugar. If Mrs.Marina is going to make one and one half of the recipe, then how much sugar does she need

Answers

1 2/3 = 5/3

5/3 + 5/6

10/6 + 5/6

she needs 15/6 or 2 3/6 or 2 1/2 cups of sugar

Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

A recipe requires 1 (2/3) cups of sugar.

That is 1 recipe requires = 1(2/3) cups of sugars

= 5/3 cups of sugar

Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :

1 recipe requires = 5/3 cups of sugar

1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar

3/2 recipe requires = (5/3) x (3/2) cups of sugar

3/2 recipe requires = 5/2 cups of sugar or 2.5 cups of sugar.

Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.

Answers

Answer:

Step-by-step explanation:

Using the sine ratio on the right triangle on the right to find x

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{70}[/tex] ( multiply both sides by 70 )

70 × sin30° = x , thus

x = 35

-----------------------------------------------

Using the sine ratio on the right triangle on the left to find y

sin42° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{y}[/tex] = [tex]\frac{35}{y}[/tex] ( multiply both sides by y )

y × sin42° = 35 ( divide both sides by sin42° )

y = [tex]\frac{35}{sin42}[/tex] ≈ 52.3 ( to the nearest tenth ) → A

Answer:

y = 52.3.

Step-by-step explanation:

Consider the larger triangle on the right:

sin 30 = x / 70

x = 70 sin 30 = 70 * 0.5

= 35.

So, considering the small triangle:

Sin 42 = 35/y

y * sin 42 = 35

y = 35 / sin 42

y = 52.3.

the length of a rectangle is 5 M more than twice its width find the area of the rectangle if it's perimeter is 20 m

Answers

The area of the rectangle is [tex]\frac{125}{9}m^{2}[/tex]

Given that the length of a rectangle is 5m more than twice its width and the perimeter of the rectangle is 20m

length of rectangle(l)=5m+2(width of rectangle)(w)

l=5+2w

The perimeter of rectangle=2(length of rectangle+width of rectangle)

Perimeter of rectangle=2(5+2w+w)

The perimeter of the rectangle=2(5+3w)

20=2(5+3w)

10=5+3w

5=3w

w=[tex]\frac{5}{3}[/tex]

l=5+2w

⇒l=5+[tex]\frac{10}{3}[/tex]

⇒l=[tex]\frac{25}{3}[/tex]

Area of rectangle =(length of rectangle)×(width of rectangle)

Area of rectangle =[tex]\frac{25}{3}[/tex]×[tex]\frac{5}{3}[/tex]

Area of rectangle = [tex]\frac{125}{9}m^{2}[/tex]

Therefore, The area of the rectangle is [tex]\frac{125}{9}m^{2}[/tex]

Consider the line y=6×-7
what is the slope of a line parallel to this line?
what is the slope of a line perpendicular to this line?

Answers

Answer:

The slope of a line parallel to this line will be: 6

The slope of the perpendicular line will be: -1/6

Step-by-step explanation:

We know the slope-intercept form

[tex]y=mx+b[/tex]

Here,

m is the slope b is the y-intercept

Given the equation

[tex]y=6x-7[/tex]

Thus, the slope of the line is: 6

The slope of a line parallel to the line:

We have already determined that the slope of the line is: 6

We know that the parallel lines have the same slope.

Thus, the slope of a line parallel to this line will be: 6

The slope of a line perpendicular to the line:

We have already determined that the slope of the line is: 6

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus, the slope of the perpendicular line will be:

[tex]\frac{-1}{6}\:\:[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]

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

Therefore, the slope of the perpendicular line will be: -1/6

10. What is the measure of angle C?
A. 25°
B. 30°
C. 60°
D. 75°

Answers

Answer:

Step-by-step explanation:

x + 5 + 3x + C = 180 All triangles have 180 degrees.

4x + 5 + C = 180

But C must be equal to 3x. Notice the markings on the lets of the triangle.

4x + 5 + 3x = 180

7x + 5 = 180 Subtract 5 from both sides

7x = 180 - 5

7x = 175

x = 25

But angle C = 3x

C = 3*25

C = 75
