Greg needs to buy plastic forks. Brand A has a box of 25 forks for $1.97. Brand B has a box of 48 forks for $2.98
Find the unit price for each brand. Then state which brand is the better buy based on the unit price.
Round your answers to the nearest cent.
Answer:
To find the price per spoon of brand A, divide the cost by the amount of spoons:
1.99 / 25 = 0.0796
Repeat this process for brand B:
3.89 / 42 = 0.0926
Brand A, at $0.08 a unit, is the better buy of brands A and B.
Hope this helps.

Given:
RS ⊥ ST
RS ⊥ SQ
∠STR = ∠SQR
Prove:
△RST ≅ △RSQ
Answer:
1.) RS ⊥ ST, RS ⊥ SQ, ∠STR ≅ ∠SQR | Given
2.) RS≅RS | Reflexive Property
3.) △RST ≅ △RSQ | AAS Triangle Congruence Property
Step-by-step explanation:
The required fill-in-the-blank below as:
1.) RS ⊥ ST, RS ⊥ SQ, ∠STR ≅ ∠SQR | Given
2.) RS≅RS | Reflexive Property
3.) △RST ≅ △RSQ | AAS Triangle Congruence Property
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
The given in question as:
RS ⊥ ST
RS ⊥ SQ
∠STR = ∠SQR
To prove:
△RST ≅ △RSQ
1.) RS ⊥ ST, RS ⊥ SQ, ∠STR ≅ ∠SQR | Given
2.) RS≅RS | Reflexive Property
According to AAS, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.
3.) △RST ≅ △RSQ | AAS Triangle Congruence Property
Hence, △RST ≅ △RSQ
Thus, the required fill-in-the-blank above is in the solution.

slope = 4
y intercept = 0
====================================================
Explanation:
Two points on this line are (8,32) and (12,48)
Apply the slope formula to get
m = (y2-y1)/(x2-x1)
m = (48-32)/(12-8)
m = 16/4
m = 4
The slope is 4.
Use a point like (x,y) = (8,32) and the slope we found to determine the y intercept b
y = mx+b
32 = 4*8+b
32 = 32+b
32-32 = 32+b-32 ... subtract 32 from both sides
0 = b
b = 0
------------------
We found that m = 4 is the slope and b = 0 is the y intercept
We go from y = mx+b to y = 4x+0, which simplifies to y = 4x
In short: the y coordinate is 4 times that of the x coordinate.
For instance, if x = 16, then
y = 4x = 4*16 = 64
Which leads to the point (16,64)
Note: the slope of 4 means it costs 4 dollars per gallon. We can think of this as the unit rate, or rate of change.
Answer:
y = 4x
Step-by-step explanation:
The relation is proportional ⇒ y = kx , k = [tex]\frac{y}{x}[/tex]
~~~~~~~~~~
(8, 32)
(12, 48)
(16, 64)
k = 32 ÷ 8 = 4
y = 4x
Members of the drama club plan to present its annual spring musical. They have $1,262.50 left from fundraising, but they estimate that the entire production will cost $1,600.00.
Answer: At least 50 Tickets
Step-by-step explanation:
Since each ticket cost $6.75 each you will have to
$1,600.00-$1,262.50 = $33.75 after that you will have to
$33.75÷$6.75 =$50

What is the domain and range?
Answer:
The domain D = {0, 1, 2, 3, 4, 5}
The range R = {3, 4}
Step-by-step explanation:
Given the ordered pairs or points on the graph
{(0, 4), (1, 4), (2, 4), (3, 3), (4, 3), (5, 3)}
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
Domain refers to all the possible sets of input values on the x-axis.It means the set of all the x-coordinates of the given points or ordered pairs on a graph will be the domain.
Thus,
The domain D = {0, 1, 2, 3, 4, 5}
Determining the range:
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
Range refers to all the possible sets of output values on the y-axis.It means the set of all the y-coordinates of the given points or ordered pairs on a graph will be the range.
Thus,
The range R = {3, 4}
Note: Please note that the duplicated elements in the range are written only once.
2. If m is inversely proportional to n, the equation must be written as
C. n= km
m
A. k=

k
B.m=-
n
D. none of the above
Answer:
mn = k
Step-by-step explanation:
Given that,
m is inversely proportional to n.
ATQ,
[tex]m\propto \dfrac{1}{n}[/tex]
or
[tex]m=\dfrac{k}{n}[/tex]
Cross multiplying both sides,
mn = k
Hence, the required equation is "mn=k".

The length and width or a rectangular courtyard is 40 feet and 30 feet, respectively. In order to make the courtyard larger, an additional 15 feet is being added to the width
Answer:
The new area is 1800feet^2
Step-by-step explanation:
Step one:
Given data
The length and width or a rectangular courtyard is 40 feet and 30 feet
we can calculate the area of the courtyard as
Area= 40*30
Area= 1200 feet^2
when the extra 15 feet is added to the width
the new width is= 30+15= 45feet
The new area is
Area= 40*45
Area= 1800 feet^2
in all the area will increase by 1800-1200= 600feet

In Ms. Regan's closet, there is one gray t-shirt for every two black t-shirts. She buys 6 gray shirts so she now has an equal number of gray and black shirts. How many gray t-shirts and black t-shirts does she own now?
Answer:
12
Step-by-step explanation:
Given That:
1 gray t-shirt for every 2 black shirt
Number of gray shirts bought = 6 to ensure that number of gray and black t-shirts are the same
Before:
If x = number of gray t-shirt
Number of black t-shirts = 2x
Now :
After buying 6 gray t-shirts
x + 6 = 2x
6 = 2x - x
6 = x
x = 6
Hence,
Numbe of gray and black t-shirt now is :
x + 6 = 6 +6 = 12
2(x) = 2 * 6 = 12

Jill is buying new appliances. The cost of the dishwasher is $459 and the cost of the microwave is $289. What is the total price including the sales tax of 7%?
Answer:
$800.36
Step-by-step explanation:
429+289=748
7% of 748= 52.36
748 + 52.36=800.36
The total price of the dishwasher and microwave after the sales tax of 7% will be $800.36.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Jill is buying new appliances.
The cost of the dishwasher is $459 and the cost of the microwave is $289.
The total amount of the dishwasher and microwave will be
Total amount = 459 + 289
Total amount = $748
Then the price of the dishwasher and microwave after the sales tax of 7% will be
Total price = 7% of $748
Total price = 1.07 x $748
Total price = $800.36
Then the total price of the dishwasher and microwave after the sales tax of 7% will be $800.36.
