The perimeter of the rectangle below is 134 units. Find the length of side RS. Write your answer without variables
Answer:
RS = 30 units
Step-by-step explanation:
Given:
Length (PS) = [tex] 4y + 1 [/tex]
Width (PQ) = [tex] 3y + 3 [/tex]
Perimeter = 134 units
Required:
RS (width)
SOLUTION:
Perimeter of a rectangle = 2(length + width)
Plug in the values into the equation
134 = 2[(4y + 1) + (3y + 3)]
134 = 2[4y + 1 + 3y + 3]
134 = 2[7y + 4]
134 = 14y + 8
Subtract 8 from each side of the equation
134 - 8 = 14y
126 = 14y
Divide both sides by 14.
126/14 = 14y/14
9 = y
y = 9
✍️RS = Width (PQ) = [tex] 3y + 3 [/tex]
Plug in the value of y
RS = tex] 3(9) + 3 [/tex]
RS = tex] 27 + 3 [/tex]
RS = 30

Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 5/8c from both sides.
Step 3: Add 1/2 to both sides.
Step 4: Multiply both sides by 8/(-15).

Lines j and k are parallel and cut by a transversal t. If m<1 = 4x – 20 and m<6 = 5x – 25, what is m<2?
Answer:
Step-by-step explanation:
m<2 = 5.
because if you subtract 5x from 4x and that equals -1x. then you add 20 to -25 that equals -5. then you divided -5 by the -1x and you get 5.

The words don't actually matter, it is the picture that has the question.
Answer:
we get [tex]\mathbf{(g \ o \ f)(4)=9}[/tex]
Option C is correct.
Step-by-step explanation:
We are given:
[tex]f(x)=-x^3\\g(x)= |\frac{1}{8}x-1|[/tex]
We need to find (g о f)(4)
For finding (g о f)(4) we will first find g(f(x)) i.e putting value of f(x) inside g(x) and then put x=4
[tex](g \ o \ f)(x)=g(f(x))\\(g \ o \ f)(x)=|\frac{1}{8}(-x^3)-1 |[/tex]
Now, putting x=4
[tex](g \ o \ f)(x)=|\frac{1}{8}(-x^3)-1 |\\Put \ x=4\\(g \ o \ f)(4)=|\frac{1}{8}(-(4)^3)-1 |\\(g \ o \ f)(4)=|\frac{1}{8}(-64)-1 |\\(g \ o \ f)(4)=|-8-1 |\\(g \ o \ f)(4)=|-9| \\\\We \ will \ use \ absolute \ value \ i.e \ 9 \\(g \ o \ f)(4)=9[/tex]
So, we get [tex]\mathbf{(g \ o \ f)(4)=9}[/tex]
Option C is correct

The senior classes at High School A and High School B planned separate trips to New York City. The senior class at High School A rented and filled 1 van and 6 buses with 372 students. High School Brented and filled 4 vans and 12 buses with 780 students. Each van and each bus carried the same number of students. How many students can a van carry? How many students can a bus carry? *
Answer:
ANSWER: each van carries 18 people and each bus can transport 59 people.
Step-by-step explanation:
Let x = number of vans
y = number of buses
Then x + 6y = 372
4x + 12y = 780
Multiply the first equation by -4: -4x - 24y = -1488
4x + 12y = 780
Adding the equations, we get -12y = -708
y = 59
Substitute for y in the equation x + 6y = 372:
x + 6(59) = 372
x + 354 = 372
x = 18

I can't answer the first question because you need to draw lines from one number to another and I'm not sure how to type that. The answer to the second question is choice 1.
Answer:
1) draw a colored in dot right above 0 with an arrow connected to it that points to the left of the graph
2) draw a white uncolored in dot right above 12 connected to an arrow that points to the left of the graph
6) draw a colored in dot right above -4 with an arrow connected to it that points to the right of the graph
7) draw a colored in dot right above 2 with an arrow connected to it that points to the left of the graph
For question 1 on the second image, the answer is Option 1. We would color in the dot right above 36 because the child an be 36 inches and still ride the ride, and we would leave the dot right above 48 uncolored because in order to ride the ride the child must be less than 48 inches they cannot be 48 inches or taller if they want to ride the ride.
Step-by-step explanation:
The inequality for the first question can be simplified to p [tex]\leq \\[/tex] 0, so just draw a colored in dot right above 0 with an arrow connected to it that points to the left of the graph (indicating that all values of p are less than or equal to 0)
The inequality for the second equation can be simplified to g < 12, so just draw a white uncolored in dot right above 12 connected to an arrow that points to the left of the graph (indicating that all values of g are less than 12)
The inequality for the problem that says 6), can be simplified to -4 [tex]\leq \\[/tex] c, so just draw a colored in dot right above -4 with an arrow connected to it that points to the right of the graph (indicating that all values of c are equal to or greater than -4)
The inequality for the problem that says 7), can be simplified to j [tex]\geq[/tex] 2, so just draw a colored in dot right above 2 with an arrow connected to it that points to the left of the graph (indicating that all values of j are equal to or greater than 2)

What is the partial fraction decomposition of
8x+19/(x+8)(x-1)?
Answer:
8x+19/(x+8)(x-1)= 5/(x+8) + 3/(x-1)
Step-by-step explanation:
Step one:
given the expression
8x+19/(x+8)(x-1)
in partial fraction the expression is
8x+19/(x+8)(x-1)= A/(x+8) + B/(x-1)
8x+19/(x+8)(x-1)= A(x-1)+B(x+8)/(x+8)(x-1)
equating the numerator we have
8x+19=A(x-1)+B(x+8)-------------------------1
to find A put x=-8 in eqn 1
8(-8)+19=A(-8-1)+B(-8+8)
-64+19=-9A
-45=-9A
A=45/9
A=5
to find B put x=1 in eqn 1
8(1)+19=A(1-1)+B(1+8)
8+19=9B
27=9B
B=27/9
B=3
The partial fraction decomposition
8x+19/(x+8)(x-1)= 5/(x+8) + 3/(x-1)

Option-B

Step-by-step explanation:
Do multiplication first since it comes before the division in this equation
1/5 · 1/2 = 1/10
Plug this value back into the equation
1/2 - 1/10 + 2/5 ÷ 7/10
Divide 2/5 by 7/10
4/7
Plug this value back into the equation
1/2 - 1/10 + 4/7
Subtract 1/10 from 1/2
2/5
Plug this value back into the equation
2/5 + 4/7
Add.

Answer:
The size of a sundae and the amount of calories it contains.
Step-by-step explanation:
The answer choice is the only one with a positive correlation, because it is the only one that isn't depleting or going down in size. No matter if you eat the sundae or what size it becomes, the calories it contains will still be the same for the whole amount.
When a car travels, gas is used and it depletes. As a snowball does when it melts. And "the temperature on Tuesday" has no correlation involved at all
