Here is the correct and complete question:
The total number of hours, t, that Trent has practiced his guitar after d days is modeled by the equation t = 3d.
Complete the table below.
d t
1
3
15
Step-by-step explanation:
For the first space, we are to determine the value of t when d is 1
From the given equation, t = 3d, put d = 1 and determine t
t = 3d
∴ t = 3(1) = 3×1
t = 3
For the second space , we are to determine the value of t when d is 3
Put d = 3 in the equation to determine t
t = 3d
∴ t= 3(3) = 3×3
t = 9
For the third space, we are to determine the value of d when t is 15.
Put t = 15 in the equation and then find d
t = 3d
∴ 15 = 3d
Divide both sides by 3
15/3 = 3d/3
5 = d
∴ d = 5

Answer:
t (is less than or equal to) 96
Step-by-step explanation:
to solve for t, you need it to be isolated. to move the 3 to the other side, you need to multiply it on both. 3 x t/3= t and 32 x 3= 96, therefore t (is less than or equal to) 96.
i hope this helps :)
Answer:
t ≤ 96
Step-by-step explanation:
t / 3 ≤ 32
(multiply both sides by 3)
t / 3 * 3 ≤ 32 * 3
t ≤ 96

What is the rate of change for the function represented
in the table?
$0.50 per book
$0.67 per book
$1.07 per book
$1.50 per book
The rate of change for the function represented in the table is 1.5.
What is Rate of change?Rate of change, also known as slope or gradient, is a measure of how quickly one variable is changing with respect to another variable. In mathematics, it is typically represented as the ratio of the change in the output variable (y) to the change in the input variable (x) over a given interval.
Let's choose the points (100, 50) and (250, 275). The change in profit between these two points is:
Δy = 275 - 50 = 225
The change in books sold between these two points is:
Δx = 250 - 100 = 150
The slope of the line between these two points is the ratio of the change in profit to the change in books sold:
m = Δy/Δx = 225/150 = 1.5
So the rate of change for the function represented in the table is 1.5,
which means that for every additional book sold, the profit increases by $1.50.

Given in the figure below, find the values of X and Z.
Step-by-step explanation:
8x-12+104=180°
= 8x=180-92
= x=88/8
= x=11°
104=y
Answer:
Step-by-step explanation:
Angles (8x - 12) and 104 are "straight angles;" their sum is 180 degrees.
Therefore, 8x - 12 + 104 = 180, or 8x - 12 = 76, or 8x = 88.
Dividing both sides by 8, we get x = 11
Angles z and 104 are vertical angles and are thus equal to one another. Thus, z = 104 degrees

Answer:

Step-by-step explanation:
To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.
To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.

Let f(x)=3x-2 and Let g(x)=x^2+4.
Find f(g(12)).
Answer:
442
Step-by-step explanation:
Find g(12) first.
12^2 + 4 = 144 + 4 = 148.
Now find f(148).
(3 x 148) -2 = 444-2 = 442.
