3 3/4 = r + 1/8
Answer:
r = 29/8 or 3 5/8
Step-by-step explanation:
so you need to make them have the same denominator so you multiply 3/4 by 2/2 to get that
this equals 6/8
add 3 so 24/8
then you subtract 1/8 from both sides
r = 29/8
simplify so 29/8 = 3 5/8
(x – 4)2 = -9 has no real solution
Answer:
x = -1/2
Step-by-step explanation:
(x - 4) * 2 = -9
Divide both sides by 2:
x - 4 = - 9 / 2
Add 4 to both sides:
x = - 1 / 2.
Answer:
Actually, it does have a solution

I agree with your first 2 answers and it might be a glitch cause that's how it was with my last school years online quizzes but I'm not positively sure about your third answer cause I haven't done the work yet... just make sure you took all the numbers and added them together then divided them by 8 cause there's 8 groups.
ngl I cant tell you what's wrong with the second question so I'm thinking somethings wrong with the coding but alrighty...

What is the gravitational PE of the same 61.2 kg person standing on the 6th floor (Each story is 2.5 m high)?
Answer: U is the change in PE, m is the mass raised through a distance h. So, given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.

1. Is the relation a function and why or why not?
{(1, 2), (2, 3), (1, 6), (4,3)}
Answer:
Its not a function, D
Step-by-step explanation:
its not a function because the x value, 1, repeats. input is x and output is y, so the input of 1 has more than one output.

Jacob started a savings account with a 1% annual simple interest rate. His principal deposit was $147. He saved the money for 6 years. How much interest did he earn after 6 years?
Answer:
The interest Jacob earns after 6 years is $8.82
Step-by-step explanation:
The given parameters are;
The simple interest rate of the savings account, R = 1%
The principal deposit to the savings account, P = $147
The time duration Jacob saved the money, T = 6 years
The formula for simple interest, I, is given as follows;
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
Substituting the known values gives;
[tex]I = \dfrac{147 \times 1 \times 6}{100} = 8.82[/tex]
The interest Jacob earns after 6 years = $8.82.
An architect is trying different dimensions for the room shown below. Write an algebraic expression the architect can use to find the area of the room then find the area when x is 6 m. Show your work.
Answer:
x² + 12
48m²
Step-by-step explanation:
Find the diagram attached.
The room can be segregated into two rectangles
The area of the room = Area of bottom rectangle + area of the top rectangle
Area of the bottom rectangle = x * (x-3) = x² - 3x
Area of the top rectangle = 3* (4+x) = 12 + 3x
The area of the room = x² - 3x + 12 + 3x
Area of the room = x² + 12
Hence the algebraic expression that the architect can use to find the area of the room is x² + 12
Given x = 6m
The area of the room = x² + 12
The area of the room = 6² + 12
The area of the room = 36 + 12
The area of the room = 48m²

Given the relation: (0,0), (5,10), (6,12), (10,20) and based on the definition of function, is that relation a function?
Why or why not?
Answer:
Yes, because the x's do not have more than one y.
Step-by-step explanation:
x y
0 0
5 10
6 12
10 20
(That's meant to be a table). Looking at the x and y table values, you can see that none of the x's have two y's. So, this relation is a function.
Find the x and y intercept of the line below
2x + 5y = 10
Answer:
x - intercept = 5
y- intercept = 2
Step-by-step explanation:
2x + 5y = 10
Write the equation in [tex]\frac{x}{a}+\frac{y}{b}=1[/tex] form
So, divide the equation by 10
[tex]\frac{2x}{10}+\frac{5y}{10}=\frac{10}{10}\\\\\frac{x}{5}+\frac{y}{2}=1[/tex]
x - intercept = 5
y- intercept = 2
Answer:
(5,0) and (0,2)
Step-by-step explanation:
Basically, all we need to do is enter 0 for both variables. We can do this because the y-value of an x-intercept will always be 0, and the x-value of a y-intercept will always be 0.
So, to find the x-intercept we can set y equal to 0 and then solve for x.
[tex]2x+5(0)=10\\2x=10\\x=5[/tex]
So the x-intercept will be (5,0).
We can do the same thing to find the y-intercept.
[tex]2(0)+5y=10\\5y=10\\y=2[/tex]
The y-intercept is (0,2)

Which measure describes how much a sample mean varies when different samples are chosen?
Step-by-step explanation:
the most common measure of how much sample mean differ from each other is the standard deviation of the sampling distribution of the mean. this standard deviation is called the standard error of the mean

A drink recipe calls for prune juice and carrot juice. This equation represents the proportional relationship between the number of quarts of prune juice (p) and carrot juice (c) in the recipe. 4p = 12c. Enter the number of quarts of carrot juice used for 1 quart of prune juice.
Answer:
The number of quarts of carrot juice used is approximately 0.3333.
Step-by-step explanation:
The proportional relationship between the quarts of prune juice (p) and carrot juice (c) in the recipe is given as;
4p = 12c
Thus for 1 quart of prune juice, the quarts of carrot juice required can be determined by;
i.e p = 1
So that,
4 x 1 = 12c
4 = 12c
c = [tex]\frac{4}{12}[/tex]
= [tex]\frac{1}{3}[/tex]
= 0.3333
The number of quarts of carrot juice used is approximately 0.3333.

15 + 15 + 10 + 10 + 10 = 60/5 = 12 ( CODE WORD)
Step-by-step explanation:
1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b
2. A proportional relationship has a constant rate of change.
ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.
3. A proportional relationship must pass through the origin in order to be a proportional relationship.
4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.
5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.

1. The base of an open rectangular tank is 3.2 m by 2.8 m. Its height is 2.4 m. It contains
water to a depth of 1.8 m. Cal culate the surface area inside the tank that is not in conta
with water.
Answer:
16.64 m
Step-by-step explanation:
Subtract the depth of the water from the height of the tank (0.6) and use this measurement for height instead. then calculate l•h•2+w•h•2+l•w
(we multiplied the length and height and the width and height by two since there’s two sides with the same measurement for each)
