4: A school has 314 boys & 310 girls. If they are to be grouped into equal classes of 26 each , how many classes will there be?
314 boys + 310 girls = 624
If they are grouped into classes of 26 students each, how many class will there be?
130 students = 5 classes
Therefore
260 students = 10 classes
260 x 2 = 520 = 20 classes
26 x 24 = 624
Number of classes = 24
Question 5).
Jim worked 48 weeks last year. Each week he worked 38 hours. If he worked an additional 240 hours of overtime, how many hours did he work in all?
Solution:
48 weeks
24hrs × 7 = 168hrs
168 x 48 = 8,064
Additional 240hrs
= 168hrs = 7 days (a week)
240hrs - 168 = 72 (3days)
168 + 72
= 240hrs + 8, 064
= 8, 304 hrs
Answer:
h = 13 units²
Step-by-step explanation:
The way to find the area of a parallelogram is to multiply the length of one side (21) and multiply it by the height:
A = l*h
We know the area and the length:
273 = 21*h
Now we solve for height.
273/21 = (21*h)/21
273/21 = h
273/21 = 13
h = 13 units²
Divide the denominator from the numerator.
For example:
1/8 is the same as 1÷8
Then do long division:
_____
8) 1
You will get 0.125
Answer:
B
Step-by-step explanation:
A 23.5*5=117.5> 95
c 95*1=95

Step-by-step explanation:
7) 4 miles = 30 minutes
8 miles = 1 hour
12 miles = 1 hour 30 minutes
16 miles = 2 hours
20 miles = 2 hours 30 minutes
8) 1 miles = 1760
2 miles = 3520
3 miles = 5280
9) convert percentage into decimals
25% = .25
260 * .25 = 65
10) 1 gallon = 16 cups
12 x 16 = 192
11) 52:70*100
(52*100):70
5200:70 = 74.29
12) 60% / 100 = .6
.6 x 25 = 15
13) 1 liter = 1000 ml
18.75 x 1000 = 18750
18750 / 8 = 3750
