Answer:
Given the equation y = -16t^2 + 96t + 3, we know a = -16, b = 96, c = 3.
Let's solve for h in this problem.
h = -b/2a
h = -(96) / 2(-16)
h = -96 / -32
h = 3 seconds
Now let's add t=3 to our equation:
y = -16t^2 + 96t + 3
y = -16*(3)^2 + 96*(3)+ 3
y = -144 + 288 + 3
We now know that the vertex is (3,147), which means that the ball's maximum height is 147 feet.
Answer:
Step-by-step explanation:
Find the height at h(0) and h(1)
h(0) = 3 ft
h(1) = -16 + 32 + 3 = 19 ft
It takes 1 second to go from 3 feet to 19 feet
(19-3) ft / 1 sec = 16 ft/sec

About 14 weeks ago, there were 42 mold spores found in a garden. After a few weeks of observation, it is determined that the number of mold spores in the garden is tripling every 7 weeks.
The number of mold spores, M, at any given time in the garden is equal to the product of the initial amount of spores, I, and 3 to the power of n, where n is the number of times the amount of mold spores has tripled.
How many mold spores are in the garden today?
A. 378
B. 91,854
C. 252
D. 1,134
Answer:
Im guessing 252 is the answer, 42 mold spores were found 14 weeks ago and each 7 weeks it trples right? so two 7 weeks fit in 14 weeks so we would multiply 42 x 2 and which gives us 84 multiply that by 3 since it triples every 7 weeks. And there's your answer, btw don't take this for granted my math is rusty (':
55 deliveries in 11 hours = 5 deliveries in __hours
1 hour
Step-by-step explanation:To solve this problem, we will need to use the unitary method.
Determining the equation:
⇒ 55 deliveries in 11 hours
⇒ 55 deliveries = 11 hours
Finding how much hours in 5 deliveries:
Divide both sides by x:
⇒ 55 deliveries = 11 hours
⇒ 55/x deliveries = 11/x hours
Simplify the numerators:
⇒ 55/x deliveries = 11/x hours
⇒ 5/x deliveries = 1/x hours
Use cross multiplication:
⇒ 5x deliveries = x hours
Divide both sides by x:
⇒ 5x/x deliveries = x/x hours
⇒ 5 deliveries = 1 hour
Answer:
1 hour
Step-by-step explanation:
let x = unknown number of hours
Set up ratios of deliveries to hours
[tex]\sf \implies 55 : 11 = 5 : x[/tex]
[tex]\sf \implies \dfrac{55}{11}=\dfrac{5}{x}[/tex]
Cross multiply:
[tex]\sf \implies 55x=5 \cdot 11[/tex]
[tex]\sf \implies 55x=55[/tex]
Divide both sides by 55:
[tex]\sf \implies x=1[/tex]
Therefore, 55 deliveries in 11 hours = 5 deliveries in 1 hour

Find the area of the composite figure.
69 square feet
48 square feet
70 square feet
82 square feet
Answer:
69ft² (69 square feet)
Step-by-step explanation:
8x7=56ft
6x2=12ft
2x1÷2=1ft
56+12+1=69ft²
Answer:
Option A, 69 square feet
Step-by-step explanation:
Step 1: Determine the area of the rectangle
[tex]A = l * w[/tex]
[tex]A = 7\ ft * 8\ ft[/tex]
[tex]A = 56\ ft^2[/tex]
Step 2: Determine the area of the second rectangle
[tex]A = l * w[/tex]
[tex]A = 6\ ft * 2\ ft[/tex]
[tex]A = 12\ ft^2[/tex]
Step 3: Determine the area of the triangle
[tex]A = \frac{h * b}{2}[/tex]
[tex]A = \frac{(7\ ft - 6\ ft)*2\ ft}{2}[/tex]
[tex]A = \frac{1\ ft * 2\ ft}{2}[/tex]
[tex]A = \frac{2\ ft^2}{2}[/tex]
[tex]A = 1\ ft^2[/tex]
Step 4: Determine the total area
[tex]A_{total} = 56\ ft^2 + 12\ ft^2 + 1\ ft^2[/tex]
[tex]A_{total}=69\ ft^2[/tex]
Answer: Option A, 69 square feet

Dylan loves reading. He went to buy books from a bookstore. A school bag and 3 books cost $180. A school bag and 5 books cost $270. How much did each book cost?
School bag _ y
book _ x
system:
y+3x=180
y+5x=270
y=180-3x (and we put that instead of 'y' in the second equation)
(180-3x)+5x=270
180+2x=270
2x=90
x=45
so one book costs $45
and school bag:
y+3×45=180
y+135=180
y=180-135
y=45
Answer:
Each book costed 45$.
Step-by-step explanation:
Let x represent the price of a school bag and y represent the price of a book.
we get the following system of equations:
x+3y=180 (equation 1)
x+5y=270 (equation 2)
using equation 1: x=180-3y
then we substitute x in equation 2 in order to find y:
180-3y+5y=270
180+2y=270
2y=270-180=90
y=90/2=45
and we know that y represents the price of a book, so each book costs 45$.

Members of a soccer team raised $1428 to go to a tournament. They rented a bus for $955.50 and budgeted $31.50 per player for meals. Write and solve an equation which can be used to determine p, the number of players the team can bring to the tournament.
Equation:
Answer: p =
Answer:
31.5p+955.5=1428
p=15
Step-by-step explanation:
31.5p+955.5=1428
−955.5 = −955.5
Subtract 955.5 from both sides
31.5p=
\,\,472.5
472.5
31.5
31.5p
=
31.5
472.5
Divide both sides by 31.5
p=15
The number of equation players the team can bring 15 players to the tournament.
Let's break down the information given in the problem:
Total amount raised: $1428
Cost of renting a bus: $955.50
Budgeted amount per player for meals: $31.50
To determine the number of players the team can bring to the tournament (represented by "p").
The total cost for the bus and meals calculated as follows:
Total Cost = Cost of Bus + (Cost per Player × Number of Players)
Using the given values, we can write this as an equation:
Total Cost = $955.50 + ($31.50 × p)
Now we can set up the equation using the total amount raised:
Total Amount Raised = Total Cost
Substitute the values:
$1428 = $955.50 + ($31.50 × p)
Now, let's solve for "p":
$1428 - $955.50 = $31.50× p
$472.50 = $31.50 × p
To isolate "p," divide both sides by $31.50:
p = $472.50 / $31.50
p = 15

Janine has 10 pieces of ribbon. She recorded the length of each piece in the line plot below. What is the total length of the four longest pieces of ribbon?
Answer:
51.25
Step-by-step explanation:
The four longest pieces are the four X’s on the farthest right.
These X’s have values of 12.75, 12.75, 12.75, and 13.
12.75 + 12.75 + 12.75 + 13
25.5 + 12.75 + 13

In the right triangle RST, point T is graphed at (2,-3) and point R is graphed at (-1,1)
Which coordinate pair describes the location of point S?
Answer: (1/2, -1)
Step-by-step explanation: The coordinates of point S can be found using the midpoint formula for the hypotenuse RT, since S is the midpoint of RT. The midpoint formula is:
Midpoint of RT = ( (x1 + x2)/2 , (y1 + y2)/2 )
Using the coordinates of R and T, we get:
Midpoint of RT = ( (-1 + 2)/2 , (1 - 3)/2 )
= (1/2, -1)
Therefore, the location of point S is (1/2, -1).

Answer:
Initially, as x increases, y is constant.
Afterward, the slope of the graph of the function equals 2 for all x between x = 3 and x = 5.
The slope of the graph equals -1 for x between x = 5 and x = 9.
The greatest value of y is y = 4, and it occurs when x = 5.
Step-by-step explanation:
Initially, the graph of the function is flat. The quantity y remains constant as x increases from x = 0 to x = 3. The linear equation that corresponds to the function in that region is y = 0. The slope is m = 0 because the graph is a horizontal line. The graph of the function starts to increase starting at x = 3. The slope, rise/run, once we solve it, is equal to 2 for when x is between 3 and 5. After x = 5, y starts to decrease as x increases. The slope of the graph between x = 5 and x = 9 is -1. The maximum value of y occurs at the top of the bump in the graph. The coordinates of the top of the bump are (5,4). Therefore, the maximum value is y = 4, and it occurs when x = 5.
