Please help out !!

Answers

Answer 1

Answer:

x = 8

Step-by-step explanation:

These are corresponding so they are congruent.

Your equation is: 14x-4=12x+12

x=8

Answer 2

Step-by-step explanation:

these numbers are corresponding angle to each other

so =>14x–4=12x+12

14x–4=12x+12collect like terms

=>14x–12x=12+4

=>2x=16 divide both side by 2 you get

=>x=8

A Ferris wheel car moves from point C to point D on the circle shown below:

Circle A is shown with points C and D on the circle and the central angle C A D marked 45 degrees. The diameter is 15 feet.

What is the arc length the car traveled, to the nearest hundredth?

5.89 feet
6.23 feet
7.46 feet
8.15 feet

Answers

Answer:

5.89 feet.

Step-by-step explanation:

I just took the test :)

The arc length the car traveled, to the nearest hundredth is 5.88 feet, the correct option is A.

What is a Circle?

A circle is a round-shaped figure with all points lie in the same plane, the distance between all the points on the circle and the center of the circle is equal.

The line that passes through the center of the circle and has end point on the circumference is called the diameter, the radius is half the measure of the diameter.

A Ferris wheel car moves from point C to point D on the circle.

Circle A is shown with points C and D on the circle and the central angle C A D marked 45 degrees.

The diameter is 15 feet.

The arc length is determined by using the formula

L = ( [tex]\rm \theta[/tex]/ 360) * 2 π r

L = ( 45 / 360) * 2 * 3.14 * r

r = diameter / 2

r = 15/2 = 7.5 ft

L = ( 45 / 360) * 2 * 3.14 * 7.5)

L = 5.8875 ft

L = 5.89 feet.

find the value of x and y

Answers

Answer:

5 = y

6.5 = x

Step-by-step explanation:

Since all the angles are the same, you can determine that all the sides are the same lengths.

8 = y + 3

8 - 3 = y

5 = y

8 = 2x - 5

8 + 5 = 2x

13 = 2x

13/2 = x

6.5 = x

Answer:

2x - 5 = 8

+5 +5

2x = 13

Divide by 2 on both sides:

X = 6.5

Y + 3 = 8

-3 -3

Y = 5

They must equal 8 since all sides are the same.

if there are 300 calories in 100 g of a certain food, how many calories are there in a 30 g portion of food

Answers

Answer:

90 calories

Step-by-step explanation:

Calories : quantity of food

there are 300 calories in 100 g of a certain food

300 calories : 100 g food

how many calories are there in a 30 g portion of food

Let x = number of calories

x calories : 30 g food

Equate both ratios

300 calories : 100 g food = x calories : 30 g food

300/100 = x/30

300 * 30 = 100 * x

9000 = 100x

x = 9000/100

x = 90

x = number of calories = 90 calories
