(8 − 10)² − 30 ÷ 5 × 6 + 2
Answer:
(8 − 10)² − 30 ÷ 5 × 6 + 2
=(-2)² -(6*6)+2=4-36+2=-30
Answer:
-30 is the answer
Step-by-step explanation:
(8 − 10)² − 30 ÷ 5 × 6 + 2
= (-2)² − 30 ÷ 5 × 6 + 2
= 4 - 30 ÷ 5 × 6 + 2
= 4 - 6 × 6 + 2
= 4 - 36 + 2
= 6 - 36
= -30
a community center is trying to raise $1680 to purchase exercise equipment. the center is hoping to receive equal contributions from members of the community. write and algebraic expression to determine how much will be needed from each person if n people contribute. Then evaluate the expression for 10, 12, 14, or 16 people.
Lets find f(n) formula
[tex]\boxed{\sf f(n)=\dfrac{1680}{n}}[/tex]
Now
[tex]\\ \sf\longmapsto f(10)=\dfrac{1680}{10}=168[/tex]

The blue line has slope +1 and passes through the point (-3, 0). Using the point-slope formula, its equation would be
y - 0 = 1 (x - (-3))
or
y = x + 3
and so f(x) is defined by x + 3 for x ≤ 0.
The red line is horizontal for 0 < x < 3, so f(x) has a constant value of 1 for this interval. We use a strict inequality because the points (0, 1) and (3, 1) are unfilled circles.
The black (?) line has slope -1 and passes through (3, 0), so its equation is
y - 0 = -1 (x - 3)
or
y = -x + 3
so f(x) is defined by -x + 3 for x ≥ 3.
Putting everything together,
[tex]f(x) = \begin{cases}x+3&\text{if }x\le0\\1&\text{if }0<x<3\\-x+3&\text{if }x\ge3\end{cases}[/tex]

Question
Joanna wants to tile a square floor that measures 8 feet on one side. If each tile is a 6-inch square, how
many tiles will she need for the floor?
O 64 tiles
O 192 tiles
O 256 tiles
O 324 tiles
The number of tiles needed to cover the floor is 256 tiles.
The given parameter:
the length of a side of the floor = 8 feet
the length of a side of the tile, = 6-inches
To find:
how many tiles she will need for the floorConvert the unit of the floor to inches
1 ft = 12 inches
8 ft = (8 x 12) = 96 inches
The area of the floor = 96 in x 96 in
The area of the floor = 9216 in²
The area of a tile = 6 in x 6 in
The area of a tile = 36 in²
The number of tiles needed to cover the floor:
[tex]number \ of \ tiles = \frac{Area \ of \ floor}{Area \ of \ a\ tile} = \frac{9216}{36} = 256 \ tiles[/tex]
Thus, the number of tiles needed to cover the floor is 256 tiles.

(Answer quickly)
Answer:
F = (T - 7M) ÷ MG
Step-by-step explanation:
T = M(7 + FG)
T = 7M + MFG
T - 7M = MFG
(T - 7M) ÷ MG = F
F = (T - 7M) ÷ MG
Answer:
Step-by-step explanation:
Remove the brackets
T = 7M + FGM Subtract 7M from both sides
T - 7M = FGM Divide both sides by GM
T - 7M

Which rational number is closest to zero 45/17 90/19 63/10 171/112 85/18
9514 1404 393
Answer:
171/112
Step-by-step explanation:
It can be helpful to write these as mixed numbers.
45/17 = 2 11/17
90/19 = 4 14/19
63/10 = 6 3/10
171/112 = 1 59/112
85/18 = 4 13/18
Then the ordering would be ...
0 < 1 59/112 < 2 11/17 < 4 13/18 < 4 14/19 < 6 3/10
The number closest to zero is 1 59/112 = 171/112.

The domain is the horizontal extent. The range is the vertical extent. An arrow on the end of the graph means it extends to infinity in the same direction. An open circle indicates a point that is not included in the graph. A square bracket in interval notation means the point is included in the interval; a round bracket (parenthesis) means the point is not included. By convention, infinity is indicated with a round bracket, because it is not a specific number.

A 6-foot board is cut into two pieces. If one piece is x feet long, express the other length in terms of x.
Answer:
6 – x ft
Step-by-step explanation:
If a 6-foot board is cut in two pieces, both lengths could be anything that add up to 6 feet since the problem did not specify where the board was cut.
So if one piece is x feet long, the other must be 6 - x feet long because:
x + (6 – x) = 6

Given that, here are the amounts of money (cents) in coins carried by 10 students in a statistics class: 50, 35, 0, 97, 76, 0, 0, 87, 23, 65.
We have to plot a stemplot for this data.
What are stem plots?A stem and leaf plot also called a stem and leaf diagram is a way of organizing data into a form that makes it easy to observe the frequency of different types of values. It is a graph that shows numerical data arranged in order. Each data value is broken into a stem and a leaf.
A stem and leaf plot is represented in form of a special table where each first digit or digit of data value is split into a stem and the last digit of data in a leaf. This " | " symbol is used to show stem values and leaf values and it is called as stem and leaf plot key.
Now, 0, 0, 0, 23, 35, 50, 65, 76, 87, 97.
As the stem and leaf plot definition states,
2 I 3 ⇒ 2 on the stem and 3 on the leaf read as 23.
3 I 5 ⇒ 3 on the stem and 5 on the leaf read as 35.
5 I 0 ⇒ 5 on the stem and 0 on the leaf read as 50.
6 I 5 ⇒ 6 on the stem and 5 on the leaf read as 65.
7 I 6 ⇒ 7 on the stem and 6 on the leaf read as 76.
8 I 7 ⇒ 8 on the stem and 7 on the leaf read as 87.
9 I 7 ⇒ 9 on the stem and 7 on the leaf read as 97.
The stems are 0, 2, 3, 5, 6, 7, 8, 9. Therefore, option C is the correct answer.
