Answer 1

Answer:

1. h = 11 cm

2. d = 220 km

Step-by-step explanation:

1. A = 1/2bh

Where,

A = 66 cm²

b = 12 cm

A = 1/2bh

66 = 1/2 * 12 * h

66 = 6h

h = 66/6

h = 11 cm

2. s = d/t

Where,

s = 110 km/h

t = 2h

s = d/t

110 = d/2

Cross multiply

110 * 2 = d

d = 220 km

W-20.5=8 please help me

Answers

This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.

We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.

w-20.5+20.5=8+20.5

w=28.5

Sonya had 30 minutes to do a three-problem quiz. She spent 10 9/10 minutes on question A and 6 3/5 minutes on question B. How much time did she have left for question C?

Answers

Answer:

time left for question C = 12 1/2

Step-by-step explanation:

Total time required for the three quiz= 30 minutes

 time spent on question A= 10 9/10 minutes

Time spent on question b= 6 3/5 minutes

Time spent on Question c= Total time required for the three quiz -( time spent on question A+Time spent on question b)

30 - ( 10 9/10 + 6 3/5)

30 -16   (9+ 6/10)

30- 16 15/10( 15/10 = 1   5/10)

30 - 16  + 1 5/10

30 - 17 5/10

From 30, we remove 1 whole number to subtract the fraction from the other number so we have

29 - 17 ( 1 -5/10)

=12 5/10 = 12 1/2
