Answer:

x = 7.5, y = 8.5

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

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

16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5

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

16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5

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

Help! 2/3x + 19 = 35

Answers

Answer:

x = 24

Step-by-step explanation:

Given equation,

→ (2/3)x + 19 = 35

Now the value of x will be,

→ (2/3)x + 19 = 35

→ (2/3)x = 35 - 19

→ (2/3)x = 16

→ x = 16 ÷ (2/3)

→ x = 16 × (3/2)

→ x = (16 × 3)/2

→ x = 48/2

→ [ x = 24 ]

Hence, the value of x is 24.

The length of a building is 60 feet. The length of the building on a scale drawing is 4 inches. Which ratio describes the scale of the drawing?

-- giving brainliest to whoever has the answer (with descriptions and such)
-- if no one else answers (but only one person), i'll be able to give five stars and a thanks

Answers

15-1… or 15:1 because 60 divided by 4 is 15 and 4 divided by 4 is 1

the ratio of the scale drawing is

1 inch on the drawing represents 180 feet in real life.

To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:

Actual length / Length on scale drawing = Scale factor

We can plug in the values we know:

60 feet / Length on scale drawing in inches = Scale factor

To solve for the length on the scale drawing in inches, we can cross-multiply:

60 feet * 1 inch / Scale factor = Length on scale drawing in inches

Simplifying:

Length on scale drawing in inches = 60 feet * 12 inches / Scale factor

We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:

4 inches = 60 feet * 12 inches / Scale factor

Solving for the scale factor:

Scale factor = 60 feet * 12 inches / 4 inches

Scale factor = 180

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

Step-by-step explanation:

18-2.5+7 there s your helllppppppppppp

Part A: The original triangle has a base of 18 feet and a height of 7 feet. To create the 2:5 scaled version of the deck, we can simply multiply the base and height of the original triangle by the scale factor of 2/5.

New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet

Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.

Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:

Area = (1/2) x base x height

Area = (1/2) x 18 x 7 = 63 square feet

To find the area of the new deck, we can use the same formula and plug in the new dimensions:

Area = (1/2) x 7.2 x 2.8 = 11.88 square feet

Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.

Part C: The ratio of the areas is:

63/11.88 = 5.303

The scale factor is:

2/5 = 0.4

To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:

5.303/0.4 = 13.2575

Therefore, the ratio of the areas is 13.2575 times the scale factor.

A salesperson uses a circle graph to represent shoe sales for one year. The central angle for the portion of the graph that represents running shoes measures 80°. If 200 running shoes were sold, how many shoes were sold?

Thanks! :)

Answers

Answer:

900. Give Braylist

Step-by-step explanation:

I'm right

To solve the problem, we can use proportions. Since the central angle for running shoes is 80 degrees, we know that the ratio of running shoes sold to total shoes sold is 80/360. This is because the total number of degrees in a circle is 360. Therefore, we can set up the proportion:

80/360 = 200/x

where x is the total number of shoes sold. Solving for x, we get:

x = (360 * 200)/80

x = 900

Therefore, the total number of shoes sold is 900.

Ever heard of BIDMAS? Brackets Indices Divide Multiply Add Subtract

This shows the order to evaluate the equation.

First you add up the things inside brackets, because B is at the beginning of BIDMAS.

Let’s say you have
(5+3) - (4-2)

You first simplify the brackets.
(5+3) = ?. = 8. Now we have
8 - (4-2)
We still need to simplify the other bracket
(4-2) = ?. = 2.

Now we have 8 - 2.

The answer is 6.

You can do the same for that long equation, just remember the order of operation - BIDMAS.

Let’s pretend the / sign means divide.
Let’s say you have 8 x 4 / 3

The order of operations is BIDMAS - Divide comes before Multiply. Sooooo… we first divide the 4 by 3. (Okay, this was a bad example cause it gives a horrible decimal) it gives us 1.3.

Now we have

8 x 1.3.

Times those together and that’s you answer.

One more example.

8 / 4 x 3

Divide comes first, right? So we divide 8 by 4. And we get 2.

Now we have 2 x 3. Times those together and you have 6!
