Answer:
They went up 16 levels.
Step-by-step explanation:
You can find that by finding the distance from -2 to 14.
To find the distance from two numbers, 
and 
, we can substitute both in the formula 
, where d is the distance between them.
99
because 0.49 is less than 0.5(0), we round it down.
Answer:
(Sorry, I only remember how to do 1 through 7)
1. -8.86
2. 17.5
3. -6.12
4. 1.66
5. 11/24
6. 4/5
7. 14
Step-by-step explanation:
1. -5.51-3.35=-8.86
2. -59.5/-3.4=17.5
3.0.85*-7.2=-6.12
4. -0.59+2.25=1.66 (The double negatives become positive)
5. 3/8+ 1/12=11/24
6. (-24/25)/(-6/5)=4/5
7. 28/2=14
Answer:
253cm²
Step-by-step explanation:
Area of the trapezoid = 1/2(b1+b2)*h
Given
h = 22cm
b1 = 10.5cm
b2 = 12.5cm
Substitute
Area of the trapezoid = 1/2(10.5+12.5)*22
Area of the trapezoid = 1/2(23)*22
Area of the trapezoid =11*23
Area of the trapezoid = 253cm²
Hence the area of the trapezoid is 253cm²
Answer:
11
Step-by-step explanation:
8 + 3*(4-3) = 8 + 3*1 = 8+3 =11
