Answer: The answer to the question is A.
Step-by-step explanation:
Answer:
y = ± 15
Step-by-step explanation:
Given
y² = 225 ( take the square root of both sides )
= ± ![\sqrt{225}](https://tex.z-dn.net/?f=%5Csqrt%7B225%7D)
y = ± 15
That is y = 15, y = - 15
Since 15 × 15 = 225 and - 15 × - 15 = 225
Alright, so since you can't multiply 2/9 into 1 super easily, we could divide it by 2 and multiply it by 9 then to get 1, so that's what we'll do. Since 3+3/5 is
15/5+3/5=18/5 (since 5 goes into 15 3 times), we can divide that by 2 to get 18/2/5=9/5. Multiplying that by 9, we get 9*9/5=81/5=the amount of minutes it would take to iron 1 shirt. Since 5 goes into 80 16 times, we can write 81/5 as 80/5+1/5=16+1/5. In addition, we need to find how long it would take to iron 5 shirts, and to do that we can multiply 1 shirt's time by 5, getting
81*5/5=405/5=81 minutes since 5 goes into 405 81 times.
Answer:
c
Step-by-step explanation:
you should divide the distance on time
so
33/6=5.5
26/4=6.5
60/8=7.5
17/2=8.5
you can see answer in this order in c
10 / .2 = 50. Answer = 50
