Answer: 8.94 ft

Step-by-step explanation:

The ladder leaning against the perpendicular wall forms a right angled triangle. As per Pythagorus theorem,

a^2 + b^2 = c^2

8^2 + b^2 = 12^2

64 + b^2 = 144

b^2 = 144 - 64 = √80= 8.94 feet

Answer: $37.50

Explanation:
1. Turn 25% into a decimal by removing the “%” and placing a “0.” in front of it. (0.25)
2. Multiply the decimal (0.25) by the original price of the car (30). (0.25x30=7.5)
3. Add 7.5 to 30 to get the answer. (7.5+30=37.5=$37.50)

In the figure, m and n are rays.
blagie [28]

Answer:

A is correct because 1 and 3 are vertical angles.

B is correct because there are 180 degrees in a triangle. 180-65-55 = 60. Angle 2 is vertical to the third angle, so angle 2 equals 60.

C is incorrect because it is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 ≠ 60.

D is correct because 3 is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 = 120.

In review, A, B, and D are correct.

I hope this helps you =)

Write three consecutive numbers starting with number n+1, where n is natural number. Find the sum of those numbers and prove tha
netineya [11]

Consecutive numbers differ by one, which means that if you start with a certain integer x, you obtain the next integer by adding one.

So, if you start with n+1, the three consecutive numbers are

n+1,\quad (n+1)+1 = n+2,\quad (n+2)+1 = n+3

The sum of these three numbers is

(n+1) + (n+2) + (n+3) = 3n+6

This number is divisible by 3 because you can write it as

3n+6 = 3(n+2)

Note that this is true in general: the sum of three consecutive numbers is always divisible by three, because it is three times the middle number.
