Answer:
2(x-4) + 2(2x+8) OR long way (x-4) + (x-4) + (2x+8) + (2x+8)
Step-by-step explanation:
2(x-4) represents the (x-4) + (x-4) in the longer version since for perimeter you add the sides. Same thing for the other side, 2(2x+8) represents (2x+8) + (2x+8).
Not sure if you need the expression solved but here:
[tex]2(x-4) + 2(2x+8)\\(2x-8) + (4x+16)\\=6x+8[/tex]
To get from first line to second, use distributive property. To get from second to third line, combine like terms.
The perimeter of a rectangle with the length of (x - 4) and width of
(2x +8) will be (6x + 8).
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
The length of rectangle = x - 4
The width of rectangle = 2x + 8
Now,
Since, The length of rectangle = x - 4
The width of rectangle = 2x + 8
We know that;
The perimeter of rectangle = 2 (Length + Width)
⇒ The perimeter of rectangle = 2 (x - 4 + 2x + 8)
⇒ The perimeter of rectangle = 2 (3x + 4)
⇒ The perimeter of rectangle = (6x + 8)

Step-by-step explanation:
The school band collected $3,240 for 380 tickets sold to their spring concert. Adult tickets were $12 each and student tickets were $6 each. How many adult tickets were sold?
160 adult tickets were sold
How to determine how many adult tickets were sold?Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.
Set up equations to represent the problem.
Let the A and S represent the number of adult and student ticket respectively. So we can write:
12A + 6S = 3,240 --- (1)
A + S = 380 --- (2)
From (2):
S = 380 - A ---- (3)
Put (3) in (1):
12A + 6S = 3,240
12A + 6 (380 - A) = 3,240
12A + 2280 -6A = 3,240
6A = 3,240 - 2280
6A = 960
A = 960/6
A = 160 tickets
Thus, the number of adult ticket sold is 160

Four points are always coplanar if they:
Four points are always coplanar if they: lie in same plane.
Firstly understanding the coplanar points. Coplanar points are refers to the points if they are present in same plane. Further defining the word "plane". Plane is the surface, which is flat and two dimensional in nature. The surface is infinite. Plane can also be referred as the analogue of 3 dimensional space, you we can also interpret the plane as extension of point or line.
So, the points that lie on different planes will not be coplanar. Now, understanding the points on lines. Two or more lines may or may not be in same plane. Subsequently, points may or may not be coplanar, depending upon the lines they are placed on. Thus, we can not definitely say that points lying on the same line are coplanar.

x and z are opposite, x= -10, where as z = 10, Hence x times (-1) equals z.
An integer is a non-fractional number real number. It can be either negative or positive, it simply cannot be a fraction.
"w", "x", and "y" are negative, and hence less than zero.

Meg is packing a shipping conditier.
There is one section of the shipping container that has not yet been packed. The space available is in the shape of rectangular
prism that measures 2 feet by 3 feet by 33 feet.
She will pack as many boxes into the available space as possible. Each box is in the shape of a cube with side length 1 foot.
The space available in the shinning container and one of the boxes are shown below.
Answer:
[tex]Boxes= 198[/tex]
Step-by-step explanation:
This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.
We have the following given parameters.
Shipping Container
[tex]Dimension: 2ft\ by\ 3ft\ by\ 33ft[/tex]
The box
[tex]Dimension: 1ft\ by\ 1ft\ by\ 1ft[/tex]
First, we calculate the volume of the shipping container.
[tex]V_A = 2ft * 3ft * 33ft[/tex]
[tex]V_A = 198ft^3[/tex]
Next, we calculate the volume of the box.
[tex]V_B = 1ft * 1ft * 1ft[/tex]
[tex]V_B = 1ft^3[/tex]
The number of box is then calculated as:
[tex]Boxes= \frac{V_A}{V_B}[/tex]
[tex]Boxes= \frac{198ft^3}{1ft^3}[/tex]
[tex]Boxes= \frac{198}{1}[/tex]
[tex]Boxes= 198[/tex]
Hence:
198 boxes will occupy the empty space

A physical fitness association is including the mile run in its secondary-school fitness test. The time for this event for boys in secondary school is known to possess a normal distribution with a mean of 450 seconds and a standard deviation of 60 seconds. Find the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds. Group of answer choices
Answer:
0.0107 = 1.07% the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 450, \sigma = 60[/tex]
Find the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.
This is the pvalue of Z when X = 312. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{312 - 450}{60}[/tex]
[tex]Z = -2.3[/tex]
[tex]Z = -2.3[/tex] has a pvalue of 0.0107
0.0107 = 1.07% the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.
A popular candy is manufactured to weigh 0.16 ounces per piece. The pieces aresold in packages of 36. If the allowable amount of variation in weight for onepiece of candy is 0.03 ounces, which of the following equations can be used todetermine the highest and lowest allowable weight, w, of a package of 36 pieces?Assume that the weight of the packaging is negligible
a. â£wâ0.16â£/36=0.03
b. â£wâ5.76â£/36=0.03
c. 36 |wâ0.16| =0.03
d. 36|w-5.76|=0.03
Answer:
B.) |w - 5.76| / 36 = 0.03
Step-by-step explanation:
Given :
Weight of individual candy piece = 0.16 ounce
Number of candy pieces per package = 36
Allowable variation in weight of individual piece = 0.03 ounces
The highest and lowest allowable weight, w of a package of 36 pieces ;
Actual manufacturing weight of entire 36 candy = (36 * 0.16) = 5.76
Allowable weight ± actual weight ≤ allowable variation
w ± 0.16 ≤ 0.03
|w - 0.16| ≤ 0.03
For the entire 36 candy pieces :
|w - 0.16*36| = 0.03 * 36
|w - 5.76| = 1.08
|w - 0.16*36| = 0.03 * 36
Could also be written as :
|w - 5.76| / 36 = 0.03
