Answer:
c. 6.5 seconds.
Step-by-step explanation:
We have been given that a a paper plane is thrown from the top of a 147-foot cliff into the water below, the height of the plane at any given time can be determined by the formula 
, where h is the height of the plane at t seconds.
To find the time, when plane will be at a height of exactly 20.25 feet, we will substitute 
in our given formula and solve for t as:
Take square root of both sides:
Since time cannot be negative, therefore, the plane will be at a height of exactly 20.25 feet after 6.5 seconds and option 'c' is the correct choice.
Answer:
n = 11
Step-by-step explanation:
The side length of a triangle are n,n-3 and 2(n-2).
The perimeter of the triangle, P = 37 units
We need to find the value of n.
Perimeter = sum of all sides
n+n-3 +2(n-2) = 37
2n-3+2n-4 = 37
4n -7 = 37
4n = 37+7
4n = 44
n = 11
So, the value of n is 11.
Answer:
No Solution
Step-by-step explanation:
There are no values of x that make the equation true.
Step-by-step explanation:
ABD+DBC+ABC =180° ( TRIANGLE)
(2x-7)°+(8x+16)°+159=180°
2x+8x-7°+16°+156=180
10x+165=180
10x=180-165
10x=15
x=15/10
x=1.5
Answer:
Cizre bought 11 pounds of almond
Step-by-step explanation:
In order to solve this problem, we can first subtract the total Cizre spent, $75, by how much she spent on figs, which is $9 because she only bought a pound:
75 - 9 = 66
So, she spent $66 on almonds, but that isn't what the question is asking. Using this information, all we have to do now is divide the total spent on almonds by the unit price per pound of the almonds:
66 / 6 = 11
And our answer is: Cizre bought 11 pounds of almonds, which seems like <u>way</u> too much for me but I guess Cizre just really likes almonds!
Hope this helps! :)
