Answer:
A. 27.3
B. 27.28
Step-by-step explanation:
You would have to round the tenth place up because of the 8 in the hundredths place, and for the hundredth place you would have to see if the thousandths place is higher than a 5 and if not don’t round up.
Answer:
a=27.3000
b=27.2800
Step-by-step explanation:
you just look at the decimal places and ignore the whole numbers for now the you look at the 2 since it is tenth the number at its back will add one to it because 8 is greater than 5 and it becomes 3 since we added 1 to 2 . our number then becomes 27.3 and the zeros you can remove them or put them it doesn't matter.

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.

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

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:
105
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.
