120 students are in the 7th grade.
2/5
How? The decimal .4 is out of ten so it’s 4/10 but then you simplify it and get 2/5
Hope this helps and have a blessed day!
Answer:
45 km^2 (C)
Step-by-step explanation:
Isolate the smaller square -
We only need two side lengths, take 3km and 3km.
3×3 = 9km^2, that's the area of the smaller square.
Isolate the larger square -
Take 6km and the other 6km
6×6 = 36km^2
Add the square's areas together to get the whole area -
36 + 9 = 45km^2
All you need to do to solve these problems is to isolate the shapes and find their area's, and finally add them together.
4x4=16 9x(-6)=-54 16+(-54)=-38 -7x-38=266
15 and a half (15.5) quarts
Get each in common units
Orange 2 gallons X 4 quart per gallon = 8 quarts
Pineapple 4 quarts no change
Cranberry 3 pints / 2 pints per quart = 1.5 quarts
Apple 8 cups / 4 cups per quart = 2 quarts
Add them all together 8+4+1.5+2=15.5
