Answer:
A combined sewer is a sewage collection system of pipes and tunnels designed to simultaneously collect surface runoff and sewage water in a shared system.
A garden shop manager tracks the inventory of seed packets in the store for a month based on
the initial amount in the store and the number of purchases per week. The function
P(t) = -34t + 200 represents the number of seed packets remaining after t weeks.
What does 200 represent in the function P(t)?
O the y-intercept of the function and the number of seed packets purchased each week
the y-intercept of the function and the initial number of seed packets at the beginning of the
month
O the slope of the function and the number of seed packets purchased each week
O the slope of the function and the initial number of seed packets at the beginning of the month
Using linear function concepts, it is found that the meaning of 200 in the function P(t) is given by:
the y-intercept of the function and the initial number of seed packets at the beginning of the month.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.In this problem, the function is:
[tex]P(t) = -34t + 200[/tex].
The slope is of m = -34 and the y-intercept is of b = 200, hence the correct option is:

A notation that correctly describes the given transformation is:

A rotation of 90° around the origin, followed by a reflection over the x-axis.
How to describe the transformation?
Here you can see that we have a rectangle in the first quadrant, and then it is moved to the third quadrant.
In the image, you can also see that the orientation of the rectangle changes, thus, we have a type of rotation.
A rotation from the first quadrant to the second quadrant would give use the desired orientation of the rectangle, and then we could reflect it over the x-axis to reach the third quadrant, so we can write the transformation as a rotation over the origin of 90° followed by a reflection over the x-axis.
I'm not sure of the notation you use in the options, but this would be written as:
[tex]R_{O, 90\°}, r_{x-axis}[/tex]
That is a rotation of 90° around the origin followed by a reflection over the x-axis.

Step-by-step explanation:
You are choosing between two different cheese wedges at the grocery store. Assume both wedges are triangular prisms with bases that are isosceles triangles. The first wedge has a base that is 2.5 in. wide and a height of 4.5 in., with the entire wedge being 3 inthick. The second wedge has a base that is 3 in. wide and a height of 4 in., with the entire wedge being 3.5 in. thick. Which wedge has a greater volume of cheese, and by how much?
The second wedge has a greater volume and it is greater by 4.125 in³.
Volume of each wedgeSince the each cheese wedge has a triangular base, its volume V = 1/2bhw where
b = length of base of triangle, h = height of triangle and w = thickness of wedgeVolume of first wedge
Given that for the first wedge, b = 2.5 in, h = 4.5 in and w = 3 in, its volume V' = 1/2bhw
= 1/2 × 2.5 in × 4.5 in × 3 in
= 33.75 in³/2
= 16.875 in³
Volume of second wedge
Given that for the second wedge, b = 3 in, h = 4 in and w = 3.5 in, its volume V" = 1/2bhw
= 1/2 × 3 in × 4 in × 3.5 in
= 42 in³/2
= 21 in³
Since V" = 21 in³ > V' = 16.875 in³, the second wedge has a greater volume.
Amount it is greater byThe amount its is greater than the first volume is the difference in their volumes. V" - V' = 21 in³ - 16.875 in³
= 4.125 in³
The second wedge has a greater volume and it is greater by 4.125 in³.

Answer:
x = 10 , EF = 8 , FG = 15.
Step-by-step explanation:
Given : If EF = 2x – 12, FG = 3x – 15, and EG = 23.
To find : find the values of x, EF, and FG.
Solution : We have given EF = 2x – 12, FG = 3x – 15, and EG = 23.
Let the line E ___F___G.
Here F is the mid point of EG . ( mid point divide the line EG cut the line EG in two equal parts)
We can say EF = FG.
EF + FG = EG -------(1)
Plug tha values EF = 2x -12 and FG = 3x - 15 , EG = 23 in equation (1).
2x - 12 + 3x -15 = 23 .
On combine like terms
2x + 3x -12 -15 = 23 .
5x - 27 + 23 .
on adding both side by 27.
5x = 23 +27.
5x = 50 .
On dividing both sides by 5.
x = 10.
Them, EF = 2 (10) -12
20 -12
EF = 8
FG = 3 (10) -15 .
FG = 30 -15 .
FG = 15.
EG = 5 +18 = 23 .
Therefore, x = 10 , EF = 8 , FG = 15.

Choose the correct answer below.
No solution
O Exactly one solution
O Infinitely many solutions
Click to select your answer.
Answer:
Infinitely many solutions
Step-by-step explanation:
Given the system:
[tex]\left \{ {{x+2y=0} \atop {10y=-5x}} \right.[/tex]
One way to do it is to use substitution. That means we want to isolate one of the variables in one equation so we can plug it into the other equation. We can isolate [tex]x[/tex] in the first equation by subtracting [tex]2y[/tex] from both sides.
[tex]\left \{ {{x=-2y} \atop {10y=-5x}} \right.[/tex]
Now we know what [tex]x[/tex] is, so we can plug it into the bottom equation.
[tex]10y=-5(-2y)[/tex]
Then we simplify the right side:
[tex]10y=10y[/tex]
Then we divide both sides by 10:
[tex]y=y[/tex]
Since [tex]y[/tex] will ALWAYS be equivalent to itself, no matter what, we know that there are infinitely many solutions.

Answer: Part A - C, Part B - 12 pieces
Step-by-step explanation:
Part A:
We know that 1/4 of Meredith's sub is bigger than 1/4 of Jim's sub, so we can set up an inequality.
Let Meredith's sub size = m; Jim's = j
Therefore, 1/4*m > 1/4*j
We can multiply both sides by 4:
m > j
Thus, the correct answer is C
Part B:
Since he had 1/4 of it left, that means he at 1 - 1/4 of it = 3/4 of his sub.
We can calculate the value of 3/4 * 16 = 12 pieces
Heather and Amanda each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same storm. Heather spent $50 on 2 rose bushes and 3 geraniums. Amanda spent $186 on y rose bushes and 12 geraniums. What is the cost of one bush and one geranium?
Answer:
one Bush costs $19 and one geranium costs $6
Step-by-step explanation:
Let the cost of one Bush be x
Let the cost of one geranium be y
If Heather spent $50 on 2 rose bushes and 3 geraniums, then the equation that represent the statement is:
2x+3y = 50….... 1
If amanda spent $186 on 6 rose bushes and 12 geraniums, then the equation representation will be:
6x+12y = 186…......2
Solve equations 1 and 2 simultaneously
2x+3y = 56..... 1 × 3
6x+12y = 186 ..... 2 × 1
.......…............
6x+9y = 168
6x+12y = 186
Subtract
9y - 12y = 168-186
-3y = -18
y = -18/-3
y = 6
Substitute y = 6 into equation 1:
2x+3y = 56
2x+3(6) = 56
2x+18 = 56
2x = 56-18
2x = 38
x = 38/2
x = 19
Hence one Bush costs $19 and one geranium costs $6
NB: note that the y rose bushes in the question was corrected and 6 rose bushes was used instead in the equation.

In the morning, Jasmine biked to her grandma's house in 45 minutes. When she was biking back home in the evening it was foggy and she went 4 mph slower. The trip back took her 1 hour and 10 minutes. How far from her house does her grandmother live?
Answer:
8.4
Step-by-step explanation
Jasmine's grandma's home will be 504 miles away from her home
What is the relation between distance[x] and time[t]?The relation between distance[x] and time [t] is -
[x] = v [t]
where v is the velocity of body.
Given is Jasmine reached her grandma's house in 45 minutes. When she was biking back home in the evening it was foggy and she went 4 mph slower. The trip back took her 1 hour and 10 minutes.
Let her grandma's home be [x] miles away form her house.
Assume that her velocity was [v] mph on her way to grandma's house.
45 = x/v
x = 45v
Her velocity on her way back home would be [v - 4] mph
70 = x/(v - 4)
x = 70(v - 4)
Equating both -
45v = 70(v - 4)
45v = 70v - 280
70v - 45v = 280
25v = 280
v = 11.2 mph
The value of [x] will be -
x = 45 x 11.2 = 504 miles
Therefore, Jasmine's grandma's home will be 504 miles away from her home

Tasha believes that she can rewrite the difference 120 − 84 as a product of the GCF of the two numbers and another difference. Is she correct? Complete the explanation. She is not correct. The GCF of 120 and 84 is 12 . So 120 − 84 can be written as 12 × 10 − × , which is × (10 − ) or × = .
Step-by-step explanation:
GCF is greatest common factor. It is also termed as HCF.
Firstly we write the factors of 120 and 84
120 = 2×2×3×5×2
84 = 2×2×3×7
HCF of 120 and 84 = 12
ATQ,
Tasha believes that she can rewrite the difference 120 − 84 as a product of the GCF of the two numbers and another difference. Let's try to write like this.
120-84 = (12×10-12×7) [using the distributive property]
= 12(10-7)
It means that the difference 120 − 84 as a product of the GCF (i.e. 12) of the two numbers and another difference (i.e. 10-7). Hence, she is correct.
