Answer:
3 1/2
Step-by-step explanation:
if you multiply 4 and 3 you 12 if you multiply 1/2 times 3 you get 1 1/2 and 1 1/2 + 12 = 13 1/2 and then you have to find a fraction that when multiplied by 4 1/2 you get 2 1/4 and 4 1/2 × 1/2 = 2 1/4 so 2 1/4 + 13 1/2 = 15 3/4
Answer:a
Step-by-step explanation:
1. A=PiR^2
A=3.14 x 6^6
A=3.14 x 36
A=113.04 m^2
V= AxH
V= 113.04 x 10
V= 1130.4 m^3
There are 1760 yards in a mile
2 miles = 3520 yards
he runs 80 yards per practice (4×20)
3520÷80= 44
he needs to do the practice 44 times.
--------------
There are 128 oz in a gallon
he brought two gallons, meaning 256 oz
each cup holds 8 oz
256 ÷ 8 = 32
he can serve 32 cups.
So the step process for this is to factor it out so this is a complex trinomial so u will have to multiply 2 by -9 and the rest should be in your notes .
then once u factor it out you rearrange those two factored brackets and example of this would be
(x+3)(2x+1)
so x+3=0
therefore x=-3. you bring the 3 over to where the zero is and change the sign
for 2x+1=0
2x=-1
2x/2=-1
x=-1/2
so for this one you isolate for x and in order to get rid of 2x you divide by 2 for both
