Answer:
0.88 (I think this is how Mrs. Futch wants it to be written)
Step-by-step explanation:
h=-16t^2+14t
(Substitute h with 0)
0=-16t^2+14t
(Factor)
0=2t(-8t+7)
2t=0 -8t+7=0
t=0 t=0.88
{0, 0.88}

Ken is cutting wooden pieces that each measure 2/3 ft long. If ken is cutting from a piece that measures 9 1/3 ft, how many pieces can ken cut
Answer:
14 pieces
Step-by-step explanation:
Given that the total length available is 9 1/3 ft long and the pieces being cut is 2/3 ft long, the number of pieces that may be cut may be computed by dividing the total length by the length of each piece
= 9 1/3 / 2/3
= 28/3 * 3/2
= 14 pieces

There is a line whose slope is 7 and whose y-intercept is -5. why is it's equation in slope-intercept form?
Answer:
y = 7x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 7 and c = - 5, then
y = 7x - 5 ← equation of line

A plant is already 54 centimeters tall, and it will grow one centimeter every month. The plant's height, H (in centimeters), after M months is given by the following.
What is the plant's height after 13 months?
Answer:
67 cm
Step-by-step explanation:
We are given the initial height of the plant let's call it H.
H = 54 cm. This is the original height of the plant at M(months) = 0.
We are given that it grows at 1 cm/month. This is the rate of growth.
Rate = 1
Time (M) is given in Months.
So when M = 0, H = 54
Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.
When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.
H = 1M + 54.
Now we just plug in 13 for M, to get 13 months.
H = 13 + 54
H = 67 cm
So our plant would be 67 cm in height after 13 months.

Step-by-step explanation:
3(5p - 1) - 4(3p - 7)
Also please explain it as well
Answer:
3p + 25
Step-by-step explanation:
Let's start with the original expression:
3(5p – 1) – 4(3p – 7)
We need to distribute each constant to the binomial they are multiplying, and when we do that, we get:
15p – 3 – 12p + 28
Why did the 28 turn out positive? We multiplied two negative numbers together, –4 and –7 , and multiplying two negatives always gives us a positive product.
Now, let's rewrite the expression to group like terms together:
15p – 3 – 12p + 28 — marked like terms, constants bold, variables underlined
15p – 12p + 28 – 3 — rewrote the expression to group like terms
Finally, we combine each set of like terms together to get our final answer:
3p + 25 — simplifying

5n = 36
Solve for n
Please show steps thanks so much
Answer:
n = 7.2
Step-by-step explanation:
I just divided both sides by 5.
5n (÷ 5) = 36 (÷ 5)
n = 7.2 or 7 [tex]\frac{1}{5}[/tex]
You can choose between using the decimal or the fraction.
Answer:
n=7.2
Step-by-step explanation:
=> 5n=36
=> 5n/5 =36/5 [Divide by 5 on both the sides]
=> n=7.2
