Answer:
Salena's got to the library first
Step-by-step explanation:
12½ miles = 25/2 miles
2½ miles = 5/2 miles
5¾ miles = 23/4 miles
114 miles = 114 miles
Salena's time of arrival =
if 5/2 miles : 5 minutes
then 25/2 miles : ?
25/2 ÷ 5/2. × 5
25/2 × 2/5 × 5
25 minutes
Justin 's time of arrival=
if 23/4 miles : 12 minutes
25/2 miles : ?
25/2 ÷ 23/4 ×12
25/2 × 4/23 ×12
26 minutes approximately
Brandon 's time of arrival=
if 114 miles : 258 minutes
25/2 miles : ?
25/2 ÷114 ×258
25/2 × 1/114×258
25 × 1/57 × 258
113 minutes approximately
A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
Answer:
22m²
Step-by-step explanation:
Area of parallelogram is simply the base length x height.
In this case, base length = 4m and height = 5.5m
hence,
Area = 4 x 5.5 = 22m²
Answer:
it is 4xy-4y^2+16x-16y
Step-by-step explanation:
My method is to "square them"
2x. -2y.
2y
8
2x * 2y
2x * 8
-2y*2y
-2y * 8
and add all the products together
In 24 hours, the worm climbs 5 feet.
7-2= 5 (the worm falls 2 feet every night)
So,
5*8=40
It will take bruce's worm about 8 days to get to the top of the well.
I hope this helps!
