Answer:
V = nl^2h or V = nw^2h
Step-by-step explanation:
The computation of the volume of the solid is given below:
Here the volume of the sold would be considered as the volume of 1 prism i.e. rectangular times n
Now as we know that
The volume of a rectangular prism is V is
lwh.
As L = w
Here cross section would become a square
So
V = l^2h
So,
The volume of the resulting solid would be
V = nl^2h or V = nw^2h

Here is a linear equation: y = 10+ 1. Are (1,1.5) and (12, 4) solutions to the equation? Select the correct choice.
Answer:
[see below]
Step-by-step explanation:
Assuming that the equation is y = 10x + 1
(12, 4)
4 = 10(12) + 1
4 = 120 + 1
4 ≠ 121
(12, 4) is not a solution.
(1, 1.5)
1.5 = 10(1) + 1
1.5 = 10 + 1
1.5 ≠ 1
They are not solutions to the equation.
Hope this helps.

Step-by-step explanation:
We get the value 22.14 - 593.42 for the given expression 31/7(5-56-78)
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 31/7(5-56-78)
Thirty one divided by seven times of five minus fifty six minus seventy eight
31/7(5-56-78)
31/7(5-134)
Thirty one by seven times of five minus one hundred thirty four.
31/7(5)-31/7(134)
155/7-4154/7
22.14 - 593.42
Hence, we get the expression 22.14 - 593.42 for the given expression 31/7(5-56-78)

Solve the following problem for the roots by using the quadratic formula.
2(6 - x) = x(x + 5)
Answer:
The roots are [tex]x=\dfrac{-7+ \sqrt{97}}{2}\text{ and }x=\dfrac{-7- \sqrt{97}}{2}[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex]2(6 - x) = x(x + 5)[/tex]
Remove the parenthesis and simplify.
[tex]12-2 x= x^2 + 5x[/tex]
[tex]x^2+7x-12=0[/tex]
Now use the quadratic formula [tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex].
Susbtitute a=1, b=7 and c=-12 in above formula.
[tex]x=\dfrac{-7\pm \sqrt{7^2-4(1)(-12)}}{2(1)}[/tex]
[tex]x=\dfrac{-7\pm \sqrt{49+48}}{2}[/tex]
[tex]x=\dfrac{-7\pm \sqrt{97}}{2}[/tex]
Hence, the roots are [tex]x=\dfrac{-7+ \sqrt{97}}{2}\text{ and }x=\dfrac{-7- \sqrt{97}}{2}[/tex].
Cindy decided to shop online. She was buying books ($6 each) and candles ($4 each). She bought 15 items and spent $78. How many books did she buy?
Answer:
9 books
Step-by-step explanation:
78=b(6)+c(4)
78=9(6)+6(4)
78=54+24
78=78-True
As per linear equation, Cindy bought 9 books online.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
Given, Cindy was buying books ($6 each) and candles ($4 each).
She bought 15 items and spent $78.
Let, she bought 'x' books.
Therefore, she bought (15 - x) candles.
Now, the cost of the total 15 items is
= $[6x + 4(15 - x)]
= $[6x + 60 - 4x]
= $[2x + 60]
Therefore, 2x + 60 = 78
⇒ 2x = 78 - 60
⇒ 2x = 18
⇒ x = 9
Therefore, Cindy bought 9 books.

Isaiah has $7.15 in Dimes and Nickels. He has a total of 91 coins. How many of each coin does he have? Group of answer choices dimes: 31 nickels 60 dimes: 60 nickels: 31 dimes: 52 nickels: 39 dimes: 39 nickels: 52
Answer:
Dimes = x = 52
Nickels = y = 39
Step-by-step explanation:
Let
Dimes = x
Nickels = y
x + y = 91 (1)
0.10x + 0.05y = 7.15 (2)
From (1)
x = 91 - y
Substitute x = 91 - y into (2)
0.10x + 0.05y = 7.15
0.10(91 - y) + 0.05y = 7.15
9.10 - 0.10y + 0.05y = 7.15
- 0.10y + 0.05y = 7.15 - 9.10
-0.05y = -1.95
y = -1.95 / 0.05
= 39
Substitute y = 39 into (1)
x + y = 91
x + 39 = 91
x = 91 - 39
x = 52
Dimes = x = 52
Nickels = y = 39

A) 4 divided by 1/5
B) 4 divided by 4/5
C) 4/5 divided by 1/5
D) 1/5 divided by 4/5
Answer:
Im pretty sure its 4 divided by (4/5 wrong)
Step-by-step explanation:
Answer:
4/5 ÷ 1.5 (C)
Step-by-step explanation:
4 sections out of 5 are shaded, this represents 4/5
1 section not shaded represents 1/5
4/5 ÷ 1/5 is the same as 4/5 · 5/1 which equals 4 (the amount shaded)
Police chases a driver. The police is 1 mile behind the driver. The speed of the police is 90 mph, and the speed of the chased car is 85 mph. How long will it take for the police to catch up with the car?
Answer:
0.20 hour
Step-by-step explanation:
According to the problem, computation of the given data are as follows,
Speed of police = 90 mph
Speed of chased car = 85 mph
Distance to be chased = 1 mile
So, we can calculate the time to catch by using following formula:
Time required = Distance between two cars ÷ (Speed of Car A - Speed of Car B)
= 1 ÷ ( 90 - 85)
= 1 ÷ 5
= 0.20 hour
Identify the solution of each equation from the list given.
1. b + 8 = 14; 4, 5,6
2. 25- t = 15; 9, 10, 11
I need answers for both please I’ll give 50 points!!
Answer:
1.) The answer is b = 6
2.) The answer is t = 10
Step-by-step explanation:
For the first equation in order to fin out the answer we do.....
b + 8 = 14
b + 8 - 8 = 14 - 8
b = 6
For the second question we do....
25 - t = 15
25 - t + t = 15 + t
25 = 15 + t
25 - 15 = 15 + t -15
10 = t

Jared drew this rectangle. Then, he drew another rectangle that was twice as long but had the same width. In what way do the area and perimeter of Jared’s new rectangle change from the area and perimeter of the original rectangle?
Answer:
Step-by-step explanation:
one rectangle has the area, A₁=LxW and,
perimeter P₁=2L+2W
the second rectangle has the area A₂=2L x W,
and perimeter P₂=2(2L)x2W= 4Lx2W
the second area doubles compared to the first area
the perimeter gets increased with double the length

Find the slope of the line that passes through the two points below."
(7,-1) and (9,0)
Answer:
1/2 or 0.5 (same value, different form)
Step-by-step explanation:
Ok...since I can't actually graph it, we can make a table out of it....
x y
7 -1
9 0
From -1 to 0, we add 1 (this is for the y section)
From 7 to 9, we add 2 (this is for the x section)
Now all we have to do is divide the y with the x
y/x = 1/2
The slope will be 1/2 (fraction form) 0.5 (decimal form)

Three ballet dancers are positioned on stage. Jada is 2 meters straight behind Trisha and 4 meters directly left of Ken. When the music begins, Jada twirls to Ken's position, then leaps to Trisha's position, and finally walks back to her original position. How far did Jada travel? If necessary, round to the nearest tenth.
Answer:
10.5 meters
Step-by-step explanation:
in their starting position all three dancers form a right triangle with legs equal to 2m and 4m.
Jada to Ken = 4m
From Ken's position to Trisha's, Jada goes another 2[tex]\sqrt{5}[/tex]m*
From Trisha's position to her original position, Jada goes another 2m

A ladder 50 dm long when set against the wall of a house just reaches a window at a height of 48 dm. How far is the lower end of the ladder from the base of the wall?
Answer:
14dm
Step-by-step explanation:
To solve this question we can use the Pythogorean theorem
a^2 + b^2 = c^2
In this case, The ladder is the hypotenuse, the height is one of the leg of the right angle triangle
Let's keep the missing side as x
If we apply the theorem,
x^2 + 48^2 = 50^2
x^2 + 2304 = 2500
x^2 = 2500 - 2304
x^2 = 196
[tex]x = \sqrt{196} \\ x = 14[/tex]
