Answer:
5
Step-by-step explanation:
Plug in the given x- and y-coordinates (in this case we'll use
for the missing variable)
Simplify
Subtract 18 from both sides (Subtraction Property of Equality)
This is very simple. So you use two formulas:
Rectangle: Length • Width
Semicircle: Area = 
With that, you do 0.8 ÷ 2 = 0.4 because we will be using radius. When solved, you get 0.2512... But for this problem, I will be rounding everything to the nearest hundredths.
Area of semicircle: ≈ 0.25
Now we solve for the rectangle. That is very easy. Just multiply 0.75 • 0.8 and you get 0.6
For this problem, I'm not sure why they make you round to the nearest centimeter, but if you do, you get 1 cm. Otherwise,
Round to nearest tenth: 0.9
Round to nearest hundredths: 0.85
Answer: 5 5/12 miles
Step-by-step explanation:
The following are the distance covered by Jada for the week.
Monday = 1 1/3 miles
Tuesday = 5/6 miles
Wednesday = 0
Thursday = 2 3/4 miles
Friday = 1 1/2 miles
Total distance for the week will be:
= 1 1/3 + 5/6 + 2 3/4 + 1 1/2
The lowest common multiple of 3,6,4 and 2 is 12. The fractions will then be
1 4/12 + 10/12 + 2 9/12 + 6/12
= 3 29/12
= 3 + 2 5/12
= 5 5/12
Jada ran 5 5/12 miles this week
10 quarts, because 2 x 2 = 4 quarts, then 1 gallon = 4 quarts, 4 + 4 = 8, then half of 4 is 2, which 8 + 2 = 10.
