Given
Plastic pipes of 5 ft are cut into 8 rods
The length of each rod will be
[tex]\Rightarrow \dfrac{5}{8}\ ft[/tex]
The total length for 13 rods are
[tex]\Rightarrow L=13\times \dfrac{5}{8}=\dfrac{65}{8}\ ft\\\Rightarrow L=8.125\ ft[/tex]

Lilah's new basketball has a diameter of 10.5 inches. What is the volume
of the air inside? Round to the nearest tenth. Use 3.14 as pi
Answer:
V = 605.8
Step-by-step explanation:
Volume of a sphere:
V = 4/3πr³
r = 2/d = 5.25
V = 4/3π5.25³
V = 4/3(3.14)(9261/64)
V = 605.8

Answer:
45°
Step-by-step explanation:
Sum of angles lying on any part(upper or lower) of a line is 180°.
=> (2x + 45°) + x = 180°
=> 3x = 180° - 45°
=> 3x = 135°
=> x = 135°/3
=> x = 45°
Can someone help me with a question!?!?
If the parent graph f(x) = x² is changed to f(x) = 2x², the vertex of the parabola will still remain (0, 0) because whenever the equation of a parabola is in the form y = ax², the vertex will always be (0, 0).
Now if a is a big number, the parabola will become narrower.
So it will stretch vertically and become narrower.

Answer:
C. 3x+2=4
Step-by-step explanation:
6x+4=8
Subtract 4 from both sides.
6x=4
Divide both sides by 6
x=4/6
Simplify it
x=2/3
3x+2=4
Subtract both sides by 2
3x=2
Divide both sides by 3
x=2/3
Hope this helps
Answer and Step-by-step explanation:
The correct answer choice is answer choice 3. [ 3x + 2 = 4 ]
6x + 4 = 8
6x = 4
x = 2/3

9. If AJKL - ANML, find the values of x and y.
Answer:
x = 35, y = 18
Step-by-step explanation:
Since both triangles are similar, their sides must be proportional with means all of them have a common ratio.
If NM = 16, and KJ = 40. 40/16 is the ratio from ∆NML to ∆JKL. The reciprocal(numerator and denominator flip, the product of a number and it's reciprocal is 1) of this is true from ∆JKL to ∆NML.
Now to find the missing sides you multiply a side by the common ratio to find it's corresponding side length.
Dividing by a number is the same as multiplying by the reciprocal of that number.
40/16 can be reduced to 5/2 or 2 ½ as a mixed fraction.
16/40 can be reduced to 2/5 or 0.4 as a decimal.
Since the scale of ∆JKL is greater than ∆NML, you multiply by 5/2 to get the corresponding side of ∆JKL from ∆NML.
Since the scale of ∆NML is less than ∆JKL, you multiply by 2/5 to get the corresponding side of ∆NNL from ∆JKL.
Therefore x = 14 × 5/2 = 70/2 = 35.
y = 45 × 2/5 = 90/5 = 18.

In parallelogram ABCD, if ED = 7x - 13 and BD = 16x - 38, find BD.
Answer:
58
Step-by-step explanation:
The length of BD is 58 units.
What are properties of parallelogram?The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal. A parallelogram's total square sum and total square sum of its diagonals are equivalent. Additionally known as the parallelogram law.
Given:
ED = 7x - 13 and BD = 16x - 38
So, the Diagonals of parallelogram bisect each other
BD = ED+ EB
16x - 38 = 2 ED { ED= EB}
16x - 38 = 2 (7x- 13)
16x - 38 = 14x - 26
2x = 12
x= 6
So, length of BD = 16(6) - 38 = 96- 38 = 58 units

There are 54 students on a school bus. The number of high school
students is 3 more than twice the number of middle school students.
How many of high schoolers are on the bus? State your answer in a
sentence.
Answer: there are 37 high school students on the bus
Step-by-step explanation:
h+m=54 total number of students
h= 2m+3 total number of HS students
2m+3+m=54 Substitute 2m+3 in for h
3m+3=54
3m=51
m=17
h+17=54
h= 37
The manager of a factory wants to compare the mean number of units assembled per employee in a week for two new assembly techniques. Two hundred employees from the factory are randomly selected and each is randomly assigued to one of the two techniques. After teaching 100 employees one technique aud 100 employees the other techuique, the manager records the aumber of uaits each of the employees assembles in one week. Which of the following would be the most appropriate inferential statistical test in this situation?
a. Oruc-sauruple z-test
b. Two-sample t-test
c. Matched Pairs t-test
d. Clai-square gooducss-of-fit test
e. One-sample t-test
Answer:
The most appropriate inferential statistic test in the present situation is the;
b. Two-sample t-test
Step-by-step explanation:
From the question, we have;
The number of subjects in each sample, n₁ = 100
The number of samples = 2
The nature of the test = To compare the two means
The value of the population standard deviation, σ = Unknown
From the given parameters, we have;
The t-test is a method of inferential statistics for determining whether the difference between the mean of two groups is significant, that is if the observed difference are due to chance, where the groups are likely to have some characteristics that are related
The t-test is utilized when testing an hypothesis, and it is used for small samples, where the population standard deviation is unknown
The types of t-test used are;
a) One-sample t-test
b) Two-sample t-test
c) Paired Sample t-test
Therefore, a two-sample t-test is most appropriate.

1. A square and a rectangle have the same area. The length of the rectangle is 32
centimeters, and the width of the rectangle is 2 centimeters. What is the length, in
centimeters, of a side of the square?
Answer:
8
Step-by-step explanation:
A=l*w
32*2=64
A=s*s
s=√A
√64
=8
The length in centimeters of the side of the square is 8 cm.
What is the area of a rectangle and a square?The area of a rectangle and a square are -
A{R} = Length x Breadth
A{S} = Side x Side
Given is that a square and a rectangle have the same area. The length of the rectangle is 32 cm and the width of the rectangle is 2 cm.
It is given that -
A{R} = A{S}
Length x Breadth = Side x Side
32 x 2 = (Side)²
(Side)² = 64
Side = 8
Therefore, the length in centimeters of the side of the square is 8 cm.

Answer:
I think it is 10
Step-by-step explanation:
Only because I believe n is still unknown and 4 must be multiplied
example
4(10 + n)
40 + 4n
now if P = 10
4(n + p)
4(n + 10)
4n + 40
Answer:
P=10
Step-by-step explanation:
4(10+n)=4(n+p)
40+4n=4n+4p
40=4p+4n-4n
40=4p
p=10
