Answer:
14.29%
Step-by-step explanation:
Let's do the count for Test #1:
2 + 5 + 6 + 1 = 14 total students
Out of which, below 70 is 2 people [only the leftmost bar]
Let's do the count for Test #2:
2 + 3 + 5 + 4 = 14 total students
Out of which, below 70 is again 2 people [only the leftmost bar]
So, to find percentage of people below 70, we divide the below 70 number of people with total number of people.
(2+2)/(14+14) = 4/28 = 14.29%
The only sensible choice is
Using the compass measure between points S and N, draw an arc to the right of line m, centered at T, intersecting the edge of circle P.
_____
Whether this will actually do what Gerald wants depends on several things:
• point Q being on line L
• point N being to the right of line M
• the intersection point of the drawn arc and circle P being point R.
We presume these things would be resolved by an attached diagram (missing here).
Let <em>h</em> represent the cost of hot dogs and <em>p</em> represent the cost of potato chips.
Customer 1: 4h + 5p = 15.50 ⇒ 3(4h + 5p = 15.50) ⇒ 12h + 15p = 46.50
Customer 2: 3h + 2p = 9.00 ⇒ -4(3h + 2p = 9.00) ⇒ <u> -12h - 8p = -36.00</u>
7p = 10.50
p = 1.50
Customer 2: 3h + 2p = 9.00 → 3h + 2(1.50) = 9.00 → 3h + 3.00 = 9.00 → 3h = 6.00 → h = 2.00
Answer: hot dog = $1.50, potato chips = $2.00
Answer:
The answer is the one at the top left corner.
(y - 12)/(x - 4) = 3/2
Hope this helped!
Answer:
x = 12 hours
Step-by-step explanation:
If one pipe fills store pool in 12 hours in 1 hour will fill 1/12 of the pool
If one pipe fills a store pool in 6 hours in 1 hour will fill 1/6 of the pool
Let call " x " number of hours needed by the third pipe to fills the pool
then in 1 hour will fill 1/x
The three pipes working together in 1 hour will fill
1/12 + 1/6 + 1/x
Now we know that the three pipes take 3 hours to fill the pool then in 1 hour three pipes will fill 1/3 of the pool, therefore
1/12 + 1/6 + 1/x = 1/3
( x + 2*x + 12) /12*x = 1/3 ⇒ ( 3*x +12 )/ 12*x = 1/3
9*x + 36 = 12*x
- 3*x = - 36
x = 36/3
x = 12 hours
