The correct answer is B.) Eight-grade students
Explanation:
The purpose of a sample is to choose a reduced number of people from a specific population to study and analyze their opinions, behavior, ideas, etc. as part of a research process. Moreover, the sample or individual selected is directly related to the purposes of the research. For example, in research about the opinions of citizens about new policies, the citizens of the specific country or city should be selected.
In this context, eighth-grade students should be selected as part of the sample because this group is directly affected by the theme of the eighth-grade dance. Also, it is the interest of this group the one that determines the final theme rather than all the students or the student government.

If a container of liquid contains 20 oz of solution, what is the number of ounces of pure acid if the given solution contains 20% acid concentrations?
Answer:
4 oz
Step-by-step explanation:
The number of ounces of pure acid if the given solution contains 20% acid concentrations is 4 ounces.
What is percent?In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".
Now it is given that,
Volume of solution = 20 oz
Acid concentration = 20%
Thus, the number of ounces of pure acid = 20% of 20
⇒ the number of ounces of pure acid = 20*20/100
⇒ the number of ounces of pure acid = 4 ounces
Thus, the number of ounces of pure acid if the given solution contains 20% acid concentrations is 4 ounces.

inches.
What is the volume of a pyramid container
if the area of its base is 100 square inches
and its height is 5 inches?

The area of the floor in a storage unit is advertised as 171 square feet, Brett calls the facility and is told that the length of the unit is 10 feet longer than its width. Which of the following one of the two dimensions of the unit?
a. 3 FT
b. 4 FT
c. 19 FT
d. 23 FT
Answer:
C. 19 ft
Step-by-step explanation:
Let
Width = x
Length = x + 10
Area = 171 ft²
Area of the floor = length × width
171 = x + 10 * x
171 = x² + 10x
x² + 10x - 171 = 0
Solve the quadratic equation using factorization method
Factors are 19x and -9x
x² + 19x - 9x - 171 = 0
x(x + 19) -9(x + 19) = 0
(x + 19) (x - 9) = 0
x = -19 or x = 9
The value of x can not be negative
Therefore, x = 9 ft
Width = x
= 9 ft
Length = x + 10
= 9 + 10
= 19 ft

D) 5cm 8cm 20cm
Answer:
the answer is simple, because you have to add up each side of the triangle and match those sides with your choices. btw its C
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Use Pythagorean Theorem:
a^2 + b^2 = c^2
For a triangle to be a triangle a^2 +b^2 has to be larger than c^2
25^2 + 13^2 = 653
22^2 = 625

7/12
Answer:
7/12 pounds
Step-by-step explanation:
1/3 * 1 = 1/3
1 = 4/4
then
1/3 * 4/4 = 1/3
1/3 * 4/4 = (1*4)/(3*4) = 4/12
1/3 = 4/1|2
1/4 * 3/3 = (1*3) / (4*3) = 3/12
1/4 = 3/12
then:
1/3 + 1/4 = 4/12 + 3/12 = (4+3)/12 = 7/12
The meal will weigh 7/12 pounds.

A mammal's surface area can be calculated by using the equation S(m) = km where s(m) is the surface area in square centimeters, k is a constant and m is the mass in grams of the mammal. What is the mass of a mammal with k = 8.5 and a surface area of 6000 square centimeters? Round answer to the nearest whole number
Answer: 706 grams
Step-by-step explanation:
s(m) = km
So 6000 = 8.5m
Divide both sides by 8.5 to isolate m
6000/8.5 = 8.5m/8.5
705.88 = m
m = 706 (rounding up)
The required surface area of the given mammal is given as square meters.
Given that,
A mammal's surface area can be calculated by using the equation S(m) = km where s(m) is the surface area in square centimeters, k is a constant and m is the mass in grams of the mammal.
The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
here,
Given expression,
S(m) = k × m
Now put S(m) = 6000 and k = 8.5
6000 = 8.5m
m = 6000/8.5
m = 705.9 square centimeters
Thus, the required surface area of the given mammal is given as square meters.

An online shoe store is having a sale. The original price of each pair of shoes is p dollars. The store sells 15 pairs of shoes and earns a total of (15p−30) dollars. a. Factor the expression using the GCF.
15p−30=
b. The discount per pair of shoes is $
Answer:
15p - 30 = p - 2
b. $2.00
Step-by-step explanation:
So if they sold 15 pairs but there's a -30 in the expression, so just divide the total discounted cost which is $30 by the number of pairs, which is 15. So 30 ÷ 15 = 2, and that's the answer to b.

{{With image this time}} (Guys I really need help with this one question) FGHIJ ~ YUVWX. Find UY and GH.
Answer:
UY = 90
GH = 4
Step-by-step explanation:
Find the ratio of FGHIJ to YUVWX.
This,
Ratio = IJ to WX
IJ : WX = 6/54 = ⅑
✔️UY corresponds to GF. Thus:
GF:UY = 1:9
GF = 10.
Therefore:
10/UY = 1/9
Cross multiply
90 = UY
UY = 90
✔️GH corresponds to UV.
UV = 36
GH:UV = 1:9
Therefore,
GH/36 = 1/9
Multiply both sides by 36
GH = 1/9 × 36
GH = 4

Equation of the straight line passing through the point (x₁, y₁) and slope 'm'
