Answer:
73.3
Step-by-step explanation:
50mi/h * 5280ft/mi * 1h/3600s = 220/3 = 73.3 ft/s
Answer:
73 1/3 feet per second
Step-by-step explanation:
50 miles per hour
50*5280/3600 = 73 1/3 feet per second
26. The first half of a play is 35 minutes longer than the second half of the play. If
the entire play is 155 minutes long, how long is the first half of the play? Write
an equation to solve the problem.
Answer:
the first half of the play is 95 minutes long
Step-by-step explanation:
155-35= 120 (you subtract 35 so you get the number if both plays lasted the same time )
120/2= 60 (you get the amount of time one play lasted without extra 35 minutes)
60+35=95 (then add 35 minutes to one play because 1 one is longer than the other one)
the first half of the play is 95 minutes long.
given the function f(x)=x^2+9 find f(x-2)
Answer:
x^2 -4x+13
Step-by-step explanation:
f(x)=x^2+9
Replace x with x-2
f(x-2)=(x-2)^2+9
FOIL
f(x-2)=x^2 -2x-2x +4+9
Combine like terms
= x^2 -4x+13

D. y = 2x – 30
explain how to solve 5+7z=19
Answer: Z = 2
Step-by-step explanation:
19 - 5 = 14
7 x ? = 14
7 x 2 = 14
Solve for x. Show work to support your answer.
1) 3x - 4x - 7 = 0
2) 5x + 7 -3x - 2 = 9
3) 6(x - 2) + 8 = 14
4) -3(4x + 2) + 5(x + 6) = -4
Answer:
I feel you should do this on your own. Trust me, this is EASY algebra. I'm currently in algebra 2.
Step-by-step explanation:
To solve these equations, you first need to move all variable numbers (Those with x) to one side of the equation, and the ordinary numbers to the other side. WHEN YOU DO THIS, REMEMBER TO FLIP THE SIGN OF THE MOVED NUMBER. if it was a positive number, it is now a negative, and vise-versa. Then add or subtract on both sides of the equation. In the end, you should come out with ONE answer on each side. Then, multiply or divide. You need to SUBSTITUTE X FOR ANOTHER NUMBER. Keep doing this until you have found the correct answer.
I will do #1 for you
3x - 4x - 7 = 0
1. move variables and numbers on opposite sides. (Make sure to flip the signs)
3x - 4x = 0 + 7
2. add and subtract
-x = 7
ANSWER FOR #1: x = 7
For that last bit just move the sign over from the x to the 7. But only in that circumstance.
You can check if this is correct by plugging the answer back into the equation as so:
3( -7) - 4(-7) = 0 + 7
-21 - -28 = 7
7 = 7
Hope I helped :)
What is the solution to this equation: -5x + 4 = 29 *
[tex]\text{Hi there! :)}[/tex]
Answer:
[tex]\huge\boxed{x = -5}[/tex]
[tex]-5x + 4 = 29[/tex]
[tex]\text{Subtract 4 from both sides:}[/tex]
[tex]-5x + 4 - 4 = 29 - 4\\\\-5x = 25[/tex]
[tex]\text{Divide both sides by -5:}[/tex]
[tex]-5x / (-5) = 25 / (-5)\\\\x = -5[/tex]
Steps to solve:
-5x + 4 = 29
~Subtract 4 to both sides
-5x = 25
~Divide -5 to both sides
x = -5

8/15 +3/15 =?
Answer:
11/15
Step-by-step explanation:
To add fractions, you add the numerators together( the top) and the bottom stays the same for this situation.
so the numerators of the fraction are 8 and 3
8+3 =11
So the answer is 11/15 and this is the most simplified it can get.

Juan tried 16 free throw attempts playing basketball. He succeeded 9 times what is the experiential probability of not succeeding on his next attempt? write as a fraction
Answer:
The probability of not succeeding next attempt is 7/16
Step-by-step explanation:
Here in this question, we are asked to write the probability of not succeeding in the next attempt given that he attempted 9 success out of 16 trials.
To calculate this probability of not succeeding, we need to get it from the number of unsuccessful throws.
Thus, if 9 throws are successful out of 16, then the number of unsuccessful throws will be 16-9 = 7
So the probability of not succeeding on next attempt will be 7/16

Find the midpoint of the segment with the given endpoints.
(-7, -7) and (6, -8)
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the x values and divide by 2.
-7+6=-1
-1/2=-1/2
For the y value, you add the y values and divide by 2.
-7-8=-15
-15/2=-7 1/2
Therefore, our midpoint is (-1/2, -7 1/2).

The price of a barrel of oil changes every weekday. The changes in price for a week are shown below. Day Price Change (Dollars) +0.58 Monday Tuesday -1.02 Wednesday -0.93 Thursday +2.39 Friday -0.30 Calculate the total price change, in dollars, for the week. Explain how you determined your answer.
Answer:
+0.72
Step-by-step explanation:
0 + 0.58 - 1.02 - 0.93 + 2.39 - 0.30 = 0.72
Starting at 0 because we are measuring the change, not the price

4. Mrs. Magee's class is collecting books to donate to the local library. The
class goal is to collect 60 books for the youth section, and Mrs. Magee's
student's have donated 15 books already. They plan to donate 3 more
books every week until they reach their goal. Which of the following could
be used to determine w, the number of additional weeks that Mrs. Magee's
class collects books?
A. 15W + 3 = 60
B. 15w - 3 = 60
C. 3w - 15 = 60
D. 3w + 15 = 60
Answer:
A
Step-by-step explanation:
You would think that 15* a number added with 3 is 60. So you would write it as 15W+3=60. Sorry if im wrong.
