Answer:
C
Step-by-step explanation:
It says he walked 2(3/4) miles in 2 hours, and it wants to know how far he walked in 1 mile, which would be that number divided by 2.
2(3/4) is the same as 2.75
2.75/2=11/8
which is equivalent to 1(3/8) miles
Answer:
D
Step-by-step explanation:
P(3) = ⅙
P(5) = ⅙
Trials are independent so,
P(3 then 5) = 1/6 × 1/6 = 1/36
Answer: C, x^2 x y^2 = z^2
Step-by-step explanation:
Pythagorean theorem
Answer:
27
Step-by-step explanation:
19√2 = 26.8701
2 sig figs is the ones place and one decimal place after (tenths place) in this problem.
Only way to find your answer is to plug 19√2 into your calc.
First we need to figure out the circumference of the gardening area. The circumference fell is the length around the circle. We can use the circumference formula:
2*pi*r or pi*d
Where r = radius and d=diameter
If you plug in the diameter of 18 ft you get:
18 * pi
= 56.55 ft
Since he can only buy whole foot amounts, we will round up to 57 ft, not down, because he can have a little extra, but can't be under the amount he needs.
Now if it cost $1.50 for every foot, we just multiply that by our footing
1.5 * 57 = $85.50
