Given :
A skyrocket is launched from a 8-foot-high platform with an initial speed of 220 feet per second.
The polynomial -16t² + 220t + 8 gives the height in feet that the skyrocket will rise in t seconds.
To Find :
How high will the rocket rise if it has a 7-second fuse?
Solution :
Since, it is given that the rocket has a fuse time of 7 seconds.
Putting value of 7 sec in given equation, we get :
Height = -16×( 7 )² + 220×( 7 ) + 8
Height = 764 m
Therefore, height of rocket in 7 second fuse is 764 m.
Graph the equation
y = -x + 3
Answer:
Step-by-step explanation:
3.(x + 2) + (2x + 3) = 23
Answer:
x = 6
Step-by-step explanation:
(x + 2) + (2x + 3) = 23
Combine like terms
3x +5 = 23
Subtract 5 from each side
3x+5-5 = 23-5
3x = 18
Divide each side by 3
3x/3 = 18/3
x = 6
Answer:
x = 6
Step-by-step explanation:
1. Remove parentheses where unneeded. x + 2 + 2x + 3 = 23
2. Add constants. x + 5 + 2x = 23
3. Combine like terms. 3x + 5 = 23
4. Subtract "5" from the constants on both sides of the equation. 3x = 18
5. Divide both sides by 3. 3x/3 = 18/3
6. Simplify. x = 6

Perry finished a 100-meter race in 7/8 of a minute. The winner of the race used 14/15 of Perry's time to finish the race. How much time did the winner use to finish the race?
Answer:
49 seconds
Step-by-step explanation:
The time perry used is 7/8 of a minute
a minute equals to 60 seconds
so the time perry used is 7/8 x 60 = 52.5 seconds
The winner used 14/15 of 52.5 seconds (perrys time)
so 14/15 x 52.5 = 49 seconds

Using the 28/36 ratio, determine the maximum allowable recurring debt for someone with a monthly income of $3,200. a. $256 b. $512 c. $640 d. $896
Answer:
a. $256
Step-by-step explanation:
The computation of the maximum allowable recurring debt is shown below:
Given ratio = 28:36
And the monthly income is $3,200
So the maximum expense on housing = 28% of $3,200 = $896
And, the maximum expense on total debt = 36% of $3,200 = $1,152
Now the maximum alloweable recurring debt is
= $1,152 - $896
= $256

Step-by-step explanation:
P, Q, R and S are four points on a circle.
PTR and QTS are straight lines.
Triangle PTS is an equilateral triangle.
Prove that triangle PQR and
triangle SRQ are congruent.
Answer:
The answer is below
Step-by-step explanation:
Given that Triangle PTS has all sides with equal lengths, it is considered is an equilateral triangle.
Similarly, with < TPS and <TSP aare both equilateral triangle because they have equal length.
Therefore, ∆ PQS and ∆ SRP are congruent based on side-angle-side theorem.
Similarly, given the fact that their congruent sides of congruent triangles are congruent, both Segment PQ is congruent to segment SR.
Also, Segment PR is congruent to segment SQ as a result of congruent sides of the congruent triangles are congruent.
Lastly, the ∆ PQR and ∆ SRQ are congruent based on the side-side-side theorem.

Cars with ABS or anti-lock brakes do not leave skid marks.
O
A. True
B. False
Cars with ABS or anti-lock brakes do not leave skid marks is a false statement.
What are Automobiles?Four-wheeled vehicle designed primarily for passenger transportation and commonly propelled by an internal-combustion engine using a volatile fuel.
Cars with ABS or anti-lock brakes are designed to prevent skidding during sudden braking.
However, it is not entirely true that they do not leave skid marks.
Skid marks can still be present, especially in certain situations such as emergency braking on a wet or slippery road surface.
ABS helps to prevent the wheels from locking up, which can reduce the length of skid marks, but they may still be present to some extent.
Therefore, it is not accurate to say that cars with ABS or anti-lock brakes do not leave skid marks, so it is false.

Graph third represents the situation if a bookstore sells art books for $25 each. There are 16 books at the store option (C) is correct.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A bookstore sells art books for $25 each. There are 16 books at the store.
Let x be the total number of books sold and y be the total amount earned:
The linear equation can be framed as follows:
y = 25x
After plotting the graph of the above linear equation we will get a graph exactly the same as mentioned in the graph third.
Thus, the graph third represents the situation if a bookstore sells art books for $25 each. There are 16 books at the store option (C) is correct.

The length of a rectangle is 3 m longer than its width. If the perimeter of the rectangle is 26 m , find its area.
Answer:
40 m²
Step-by-step explanation:
First, find the perimeter. Using the perimeter formula, p = 2l + 2w, solve for the side lengths of the length and width.
Let w represent the width. The length can be represented by w + 3, since the length is 3 m longer than the width.
Plug in 26 as the perimeter, and plug in w and w + 3 for the width and length:
p = 2l + 2w
26 = 2(w + 3) + 2w
Simplify and solve for w:
26 = 2w + 6 + 2w
26 = 4w + 6
20 = 4w
5 = w
Find the length by adding 3 to this:
5 + 3
= 8
Now, find the area using the area formula, A = lw
Plug in the length and width:
A = lw
A = 8(5)
A = 40
So, the area of the rectangle is 40 m²

Ali and billy ran around a race track. How many more metres did Ali ran than billy in one lap? (Find perimeter)
Answer:
Ali ran 25.13 m more than bily
Step-by-step explanation:
From the diagram, we can see that bully runs with the inner track line while Ali runs with the outer track line.
Thus;
Diameter of inner semi circle = 20 m
Diameter of outer semi circle = 20 + 4 + 4 = 28 m
Perimeter of inner semi circle = πD/2 = 10π
Perimeter of outer semi circle = πD/2 = 14π
Now, perimeter of Billy = 80 + 80 + 10π + 10π = 222.83 m
Perimeter of Ali = 80 + 80 + 14π + 14π = 247.96 m
Thus, in one lap, difference in distance between Ali and billy = 247.96 - 222.83 = 25.13 m
