Ethan spent 12.5% of the money in his pocket on dinner. His dinner cost $15.25. How much did he have in his pocket? Group of answer choices $102.00 $172.36 $190.63 $122.00
Answer:
$122
Step-by-step explanation:
Let total money in his pocket = $ x
12.5% of x = $ 15.25
[tex]\frac{12.5}{100}*x= 15.25[/tex]
Multiply both sides by 100
12.5 *x = 15.25*100
125.5 *x = 1525
Divide both sides by 125.5
[tex]x = \frac{1525}{12.5}\\\\[/tex]
x = $ 122
he baseball team pitcher was asked to participate in a demonstration for his math class. He took a baseball to the edge of the roof of the school building and threw it up into the air at a slight angle so that the ball eventually fell all the way to the ground. The class determined that the motion of the ball from the time it was thrown could be modeled closely by the function
h(t)=16t^2+64t+80
Where h(t) represents the height of the ball in feet after t seconds.
1. By looking at the equation, how can you determine whether the function has a maximum or a minimum value? (1 point)
2. Find the maximum or minimum value of the function algebraically. After how many seconds did the ball reach this value? Show how you found your answers. (2 points)
3. Evaluate h(0). Explain this value in the context of the problem. (1 point)
4. How long is the ball in the air? Justify your answer. (2 points)
5. State the domain of the function in interval notation, and explain the restrictions on the domain based on the context of the problem. (2 points)

PLEASE HELP!! school is over in a week for me and i have A LOT of work to be done, IM BEGGING!! NO LINKS OR FILES!!!!!
Answer:
System of equations
160 = 2W + 2L
W = L - 16
Solution to system of equations
W = 32 ft
L = 48 ft
Explanation:
The width is 16 feet less than the length, so the appropriate equation for that is ...
... W = L - 16
Using this expression for W, we can substitute into the equation for perimeter:
... 160 = 2(L - 16) + 2L
... 160 = 4L -32 . . . . . . . collect terms
... 192 = 4L . . . . . . . . . . add 32
... 48 = L . . . . . . . . . . . . divide by 4
... W = 48 -16 = 32 . . . . find W using the relation with L
Length is 48 ft; width is 32 ft.

The mean age of the members of a baseball team is 28, the median age is 24, and the ages range from 20 to 45. Which of the following statements is best supported by the data?
Answer:
half are 28 or older
Step-by-step explanation:
also, im taking a math test i have the same question on my jupiter and the same amount of questions. could u send me the answers to all the questions if thats possible :) thx sm
The required statement by the details is an option (D) that half of the players are 24 or younger.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
Here,
We are given that the mean age of the members of a baseball team is 28 and the median age is 24. We can use this information to eliminate some answer choices.
Option (A) states that more than half of the players are older than 28. Since the median age is 24 and the ages range from 20 to 45, this option is not supported by the data.
Option (B) states that half of the players are 28 or older. Since the median age is 24 and the ages range from 20 to 45, this option is not supported by the data.
Option (C) states that the mode of the data is less than 28. We do not have enough information to determine the mode, so this option could be true or false.
Option (D) states that half of the players are 24 or younger. Since the median age is 24, this option is supported by the data.
Therefore, the best-supported statement by the facts is option (D) that half of the players are 24 or younger.

If the slope is 3 and one ordered pair on the line is (2,9), what is the equation?
I'll give you brainliest if it's correct!
Answer:
y = 3x+3
Step-by-step explanation:
we can find the equation of the line with this formula:
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point and m the slope
so we have
y-9 = 3(x-2)
y = 3x-6+9
y = 3x + 3
What is the value of y?

Find the equation for the
following parabola.
Vertex (2, -1)
Focus (2, 3)
Answer:
(x−2)^2=16(y+1)
Step-by-step explanation:
The equation for the parabola is (x - 2)² = 16(y + 1) if the vertex of the parabola is (2, -1) and focus of the parabola is (2, 3) option (D) is correct.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have:
The vertex of the parabola = (2, -1)
The focus of the parabola = (2, 3)
As we know, the vertex form of the parabola is given by:
(x - h)² = 4a(y - k)
(h, k) is the vertex of the parabola:
(x - 2)² = 4a(y - (-1))
(x - 2)² = 4a(y + 1)
The value of a can be found using the formula:
a = √[(c-h)² + (d-k²]
(c, d) is the focus of the parabola:
(c, d) = (2, 3)
a = √[(2-2)² + (3-(-1))²]
a = √ (3+1)²]
a = 4
(x - 2)² = 4(4)(y + 1)
(x - 2)² = 16(y + 1)
Thus, the equation for the parabola is (x - 2)² = 16(y + 1) if the vertex of the parabola is (2, -1) and focus of the parabola is (2, 3) option (D) is correct.

Height = 25.7
Formula for area of trapezoid
(b1+b2)h/2
Lets Input
(15+37)25.7/2
1336.4/2 = 668.2
Now lets multiply by 20, or the length
668.2 x 20 = 13364
