Two adults and 3 children
2 x 10= 20
3 x 2 = 6
20+6= 26
10a+2c
Hi there! I believe the answer is 1080!
Step-by-step explanation:
First, find out how many bricks were stacked in one hour. The two hour rate was given, so just divide 1440 by 2. That gives you 720. So you have the one hour down. (It's easier to work with one hour.)
Next, you need to find out how many bricks are stacked in the 0.5 period of time. That, you get by just dividing 720 by 2.(because 720 is how many bricks were stacked in one hour) And that gets you 360!
Now, to find the full answer, (1.5 hour brick rate) just add the two numbers.
720+360= 1080
Hope this helps c:
Toodles~
Answer:
(1, 1), (2, 2), (-3, -3), (4, 4), (-5, -5)
Step-by-step explanation:
You get a straight line. As you can see in the picture, the figure lies in the first and third quadrant.
Answer:
17 seconds
Step-by-step explanation:
h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..
28 = -2t² + 34t + 28
Now solve for t...
0 = -2t² + 34t (subtract 28 from both sides)
0 = t² - 17t (divide both sides by -2)
0 = t(t - 17) (factor out a t)
So
t = 0
or
t - 17 = 0
t = 17
0 seconds is the initial height. At 17 seconds, the ball will return to that height
i hope this work for you
