The two angles with the variable x form a linear pair and therefore:

Angles 16x - 18 and 12y are congruent as vertical angles:

Answer:

x = 7.5

y = 8.5

Step-by-step explanation:

Linear Pair

Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

To find x, equate the sum of the two angles with the variable x to 180° and solve:

⇒ (16x - 18)° + (10x + 3)° = 180°

⇒ 16x - 18 + 10x + 3 = 180

⇒ 26x - 15 = 180

⇒ 26x = 195

⇒ x = 7.5

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Therefore:

⇒ (16x - 18)° = 12y°

Substitute the found value of x into the equation and solve for y:

⇒ 16x - 18 = 12y

⇒ 16(7.5) - 18 = 12y

⇒ 120 - 18 = 12y

⇒ 102 = 12y

⇒ y = 8.5

Answer:

228

Step-by-step explanation:

[Formulas Below]

Surface area means the sum of all the shapes on the figure, which means we have to calculate each area of the shapes on the triangular right prism and add them up. To calculate the triangles, we plug in 6 and 5 and get 15. Since there are 2 triangles, we multiply it by 2. Next, we have to find the areas of the rectangles. 11 * 6.5 = 71.5 (There are two of them so you multiply by 2), and 11 * 5 = 55. Finally, we add all of these up. 15 * 2 + 71.5 * 2 + 55 = 30 + 55 + 143 = 228. The surface area is 228.

Area of Triangle = (Length * Height)/2

Area of Rectangle = Length * Width

Answer:

252 square yards.

Step-by-step explanation:

To find the square yardage of the roof of the building, we need to calculate the area of the shaded triangle and the area of the shaded rectangle.

First, let's calculate the area of the triangle:

Base of the triangle = 6 divisions = 6 x 2 yards = 12 yards

Height of the triangle = 5 divisions = 5 x 2 yards = 10 yards

Area of the triangle = (1/2) x base x height

= (1/2) x 12 yards x 10 yards

= 60 square yards

Next, let's calculate the area of the rectangle:

Length of the rectangle = 8 divisions = 8 x 2 yards = 16 yards

Width of the rectangle = 6 divisions = 6 x 2 yards = 12 yards

Area of the rectangle = length x width

= 16 yards x 12 yards

= 192 square yards

To find the square yardage of the roof, we add the area of the triangle and the area of the rectangle:

Total area = 60 square yards + 192 square yards

Answer:

  4600 miles

Step-by-step explanation:

You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.

The speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...

  A speed - B speed

  45000 mi/(5 h) - 79200 mi/(18 h) = 4600 mi/h

Explorer B travels 4600 fewer miles in an hour than Explorer A.

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:

90

Step-by-step explanation:

when  you multiply two negative integers they always equal positive so in this case its (-9) x (-10), you can just do 9x10 which gets u 90

Multiplying two positive integers always result in a positive integer.

Multiplying two negative integers always result in a negative integer.

Multiplying a positive or negative integer always result in a negative integer.

You add the price of both pumpkins together to get the price of the pumpkins before tax. Then you multiply it by (1 + 0.07) because 1 is the regular price plus the sales tax which is a percent that can be converted to decimal to 0.07. You multiply these together and get 35.31

Answer:

D. 36 C. 33.5 A. 20.5 B. 19.5

Step-by-step explanation:

The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.

Answer: No Clare can't purchased 2 pretzels, 2 drinks, and 2 bags of popcorn

Step-by-step explanation:

Given:

Pretzel = 3.25

Drinks = 1.85

Popcorn = 0.99

No more than $10

To Find:

Could Clare have purchased 2 pretzels, 2 drinks, and 2 bags of popcorn?

Solution:

2 pretzels = 3.25x2

2 Drink = 1.85x2

2 Popcorn = 0.99x2

3.25x2 = 6.5

1.85x2= 3.7

0.99x2= 1.98

Then add all the answer up

6.5+3.7+1.98= 12.18

Therefore, Clare can't purchased 2 pretzels, 2 Drink, and 2 bags of popcorn.

She can buy 2 pretzels, 1 Drink, and 1 bag of popcorn and Cost 9.34 and still have 0.66

Answer: 26

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.

Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.
