What Does X Equal?What Is The Measure Of Angle CAB?What Is The Measure Of CBA?(explain Your Answer And

Answers

Answer 1

Answer:

X =14

Step-by-step explanation:

All numbers in degrees

1. because All triangles have internal angles that add up to 180

1) 180 - 90 = 90

1. you subtract 90 because all right angles = 90 and you have one right angle

2) 90 = 2x + 3x-20

2. subtract the other angles from the whole (90)

3) 90 = 5x - 20

3. combine like terms

4) 70 = 5x

4. Subtract 20 from whole

5. divide by 5 on both sides

5) X = 14

Hope this helped :)

Answer 2
x=14
angle cab= 28 because 2*14 = 28
angle cba = 22 because 3*14=42-20=22

The total cost to attend the university Daniel wants to attend is going to be $12,000 for the first year.

A scholarship will pay $2,500.
His parents agreed to pay half of what remains after the scholarship is applied to the tuition.
Which amount is closest to the minimum that Daniel will need to save every month in order to pay off the remaining cost at the end of 12 months?

Answers

Answer:

$395.83

Step-by-step explanation:

to solve, we first need to subtract what we already have, first the scholarship, wich is a set amount being taken from the original amount

12'000 - 2'500 = 9'500

now we have the second subtracting factor, but this one isn't set in stone and defined, it is half of the amount his parents will pay, so what we can do is divide what we have by two, wich will give us 2 halves

9'500 / 2 = 4'750

now all we have to do is divide again but this time for each month that Daniel needs to save up in, in this case 12

4'750 / 12 = 395.83 (note1)

and there we have it, that is the minimum amount Daniel would save each month

note1: (3 goes on for infinity, usualy this is represented by a line above the repeating number, this is the case of a repeating decimal)

Find the area of the figure. Round to the nearest tenth if necessary.

A. 12.28 km²
B. 45.18 km²
C. 22.08 km²
D. 18.56 km²

Answers

9514 1404 393

Answer:

  A.  12.28 km²

Step-by-step explanation:

The area of the figure is the sum of the areas of its parts. The area of the triangular part is ...

  A = 1/2bh

  A = 1/2(3 km)(4 km) = 6 km²

__

The area of the semicircular part is ...

  A = 1/2πr²

  A = 1/2(3.14)(2 km)² = 6.28 km²

__

Then the area of the figure is ...

  6 km² + 6.28 km² = 12.28 km²

On another Ferris wheel, a car will travel 100.48m once around the wheel. What is the height from the top car to the bottom car?

Answers

Answer:

the hieght will be 58.10m

Step-by-step explanation:

the height will be 58.10m is the top car to the bottom car.

What is Ferris wheel?

A Ferris wheel, also known as a Giant Wheel or an observation wheel, is a type of amusement ride that consists of a rotating upright wheel with multiple passenger-carrying components attached to the rim in such a way that they remain upright as the wheel rotates, usually due to gravity.

These components are commonly referred to as passenger cars, cabins, tubs, gondolas, capsules, or pods. Electric motors rotate each car individually to keep it upright on some of the biggest modern Ferris wheels  which feature cars mounted on the outside of the rim.

In order to serve as a landmark for the 1893 World's Columbian Exposition in Chicago, George Washington Gale Ferris Jr. developed and built the original Ferris Wheel.

Therefore, the height will be 58.10m is the top car to the bottom car.
