At a baseball game, hot dogs cost $2.25 and drinks cost $1.75. The total cost, t, for h hot dogs and drinks can be described by the equation.
T=2.25h+1.75d
•a. Rewrite the equation to find d.
•b. Which properties allow you to isolate d?
•c. If Costas spent $18.25 and bought 5 hot dogs, how many drinks did he buy?
Answer:
The answer is below
Step-by-step explanation:
a) T=2.25h+1.75d
To rewrite the equation to find d, we have to make d the subject of the formula.
T=2.25h+1.75d
Subtract 2.25h from both sides:
T - 2.25h = 2.25h + 1.75d - 2.25h
1.75d = T - 2.25h
Divide both sides by 1.75
1.75d/1.75 = (T - 2.25h) / 1.75
d = (T - 2.25h) / 1.75
b) Additive property and law of division
c) The money spent (T) = $18.25 and the number of hot dogs (h) = 5. To get the number of drinks, substitute the value of h and T in the equation d = (T - 2.25h) / 1.75. Hence:
d = (T - 2.25h) / 1.75
d = (18.25 - 2.25(5)) / 1.75
d = (18.25 - 11.25) / 1.75 = 7 / 1.75
d = 4
The number of drinks that can be bought is 4
Subtract 12h+1 from 34h+4 . what is the answer? a.−1/4h+5 b.1/4h+5 c.−1/4h d.1/4h+3
Answer:
D
Step-by-step explanation:
We would like to solve:
(3/4h + 4) - (1/2h + 1)
This is equivalent to:
3/4h + 4 - 1/2h - 1
First, combine like terms; that is, combine the terms with h in them and combine the terms without h in them:
3/4h - 1/2h + 4 - 1
The common denominator for 3/4 and 1/2 is 4, so:
3/4h - 1/2h = 3/4h - 2/4h = 1/4h
Put this back in:
1/4h + 4 - 1
1/4h + 3
The answer is thus D.

for each diagram, determine whether angles 1 & 2 are adjacent angles, heeeelp please :(
Answer:
Diagram 5: Not adjacent angles
Diagram 6: Not adjacent angles
Diagram 7: Are adjacent angles
Diagram 8: Are adjacent angles
Step-by-step explanation:
In order for angles to be adjacent, they need to have all of three things:
1. Have a common vertex
2. Have a common side
3. Must not overlap
Diagram 5 does not have a common side between angles 1 and 2, so it is not adjacent.
Diagram 6 does not even have angles 1 and 2 connected in any way so it is not adjacent.
Diagrams 7 and 8 have all three conditions, so those diagrams are adjacent.
You spend $30 20 on 4 CDs Each CD costs the same amount and is on sale for 80% of the original price
2 Write and solve an equation to find how much you spend on each CD. Let p represent the price you pay for each CD
Equation QS-2240
You spent $ 5.5 on each CD
The next day, the CDs are no longer one sale You have $25. Will you be able to buy 3 more CDS?
Yes you will
be able to buy 3 more CDs
Explain your reasoning for part b).
Each CD COSTS
at the regular price, so 3 CDs would cost $
Answer:
You will only be able to buy two at the original price the following day.
Step-by-step explanation:
You spend $30.40 on 4 CDs. Each CD costs the same amount and is on sale for 80% of the original price.
If x = original cost of one CD
80% of one CD = 0.8x
0.8x = the price you pay for one discounted CD
You buy 4 of the discounted CDs for $30.40
4(0.8x) = 30.40
solve for x, the original cost of one CD
3.2x = 30.40
x = 9.50
The next day, the CDs are no longer one sale. You have $25. Will you be able to buy 3 more CDs?
25$ / $9.50 = 2.63 CDs
Onna received a $80 gift card for a coffee store. She used it in buying some coffee that cost $8.09 per pound. After buying the coffee, she had 39.55 left on her card. How many pounds of coffee did she buy?
Answer:
She bought 5 pounds
Step-by-step explanation:
Original worth of gift card = $80
Balance on card after purchase = $39.55
Amount used for purchase = 80 - 39.55 = $40.45
Next let us determine how many pounds of coffee she bought as follows:
Price of coffee = $8.09 per pound
amount spent on coffee = $40.45
Lett the number of pounds of coffee she bought be x
$ 8.09 = 1 pound
$40.45 = x pounds
since $8.09 = 1 pound
[tex]\$\ 1 = \frac{1}{8.09}\ pounds[/tex]
[tex]\$\ 40.45 = 40.45 \times\ \frac{1}{8.09} \\= \frac{40.45}{8.09}\\ = 5\ pounds[/tex]

A company manufactures bracelets. The cost C (in dollars) of manufacturing n bracelets is given by the equation C = 8n + 500
The revenue R (in dollars) that is generated from selling n bracelets is given by the equation R = 35n - 0.1n?
The company breaks even when cost and revenue are equal. For which values of n does the company break even?
A. O 10 and 500
В.
25 and 200
C
20 and 250
D.
50 and 100
The values of n which the company break even are option (c) n = 20 and n = 250
How to determine the values of n at the break even point?From the question, the parameters are given as
Cost function, C(n) = 8n + 500
Revenue function, R(n) = 35n - 0.1n²
At the break even point, the functions C(n) and R(n) have the same value
This is represented as
C(n) = R(n)
Substitute the known values in the above equation
So, we have the following equation
8n+ 500 = 35n - 0.1n²
Collect the like terms
-0.1n² + 35n - 8n = 500
So, we have
-0.1n² + 27n - 500 = 0
Divide both sides by -0.1
n² - 270n + 5000 = 0
Factorize
(n -20)(n - 250) = 0
Solve for n
n - 20 = 0 and n - 250 = 0
This gives
n = 20 and n = 250
Hence, the company breaks even at n = 20 and n = 250

If anyone knows how to do this stuff I would love some help (✿◠‿◠)
Answer:
See explanation below
Step-by-step explanation:
(a) The spread of the data is represented by their range,
Adam's Range : 106 - 91 = 15
Miguel's Range : 105 - 86 = 19
As Miguel's Range is greater, his data has the greater spread
(b) The middle 50 percent of both data sets would be the following,
Adam | 103 | 105 | 104 | 106 | 100
Miguel | 88 | 86 | 89 | 93 | 105
And their 50% range would be ...
Adam's 50% Range : 106 - 100 = 6,
Miguel's 50% Range : 105 - 86 = 19
Adam still has the least spread, even in the middle 50%
(c) This proves that their is a small variance in Adam's training times, but a large variance in Miguel's training times (Miguel's data is more likely skewed).

Hari borrowed Rs. 126000 from a money-lender at 15% per annum simple interest,
After 3 years, he paid Rs. 70700 and gave a buffalo to clear off the debt. What is the
cost of the buffalo?
Answer:
Rs. 112000
Step-by-step explanation:
Borrowed money = Rs. 126000Interest rate = 15% PA simpleTime = 3 yearsHari is due to pay after 3 years:
126000* (1+ 3*15/100) = 182700He pays Rs. 70700, remaining money is cleared by giving buffalo.
Cost of buffalo:
182700 - 70700= Rs. 112000Answer is: Rs. 112000
Answer:
Solution,
principal(P)= Rs. 126000
Rate(R)=15%
Time(T)=3 years
Money paid=Rs.70700
Cost of buffalo=?
We know that,
Interest=P*T*R
100
= Rs. 126000*3*15
100
= Rs. 56700
Now,
Amount(A)=P+I
=Rs. ( 56700+126000)
= Rs.182700
Again,
by the question,
Cost of buffalo= Amount- Money paid
= Rs.(182700- 70700)
= Rs. 112000
Therefore, the cost of buffalo is Rs. 112000.

how to find the surface area and the volume of trapezoidal prisms? (need some formula)
Step-by-step explanation:
Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2
Area of a trapezoid is found with the formula, A=(a+b)/2 x h.
Answer:
To find the surface area, the amount of space on the outside of a solid, of a trapezoidal prism, you'll need to find the area of the trapezoid base and multiply it by two. You'll then add the area of the four rectangles to the area of the two bases. Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2.
.A straight line passes through point A(2,4) and B(6,12). Find the equation of the perpendicular bisector of line AB (write your answer in the form ax+by=c)
Answer:
x + 2y = 20
Step-by-step explanation:
We require the slope and the midpoint of AB
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A(2, 4) and (x₂, y₂ ) = B(6, 12)
m = [tex]\frac{12-4}{6-2}[/tex] = [tex]\frac{8}{4}[/tex] = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]
-----------------------------------
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]
Thus midpoint of AB = ( [tex]\frac{2+6}{2}[/tex], [tex]\frac{4+12}{2}[/tex] ) = (4, 8 )
--------------------------------------------
y = - [tex]\frac{1}{2}[/tex] x + c ← partial equation of perpendicular bisector
To find c substitute (4, 8) into the partial equation
8 = - 2 + c ⇒ c = 8 + 2 = 10
y = - [tex]\frac{1}{2}[/tex] x + 10 ← in slope- intercept form
Multiply through by 2
2y = - x + 20 ( add x to both sides )
x + 2y = 20 ← in the form ax + by = c

Perform two translations to the parallelogram below to transform it into an irregular polygon
that can tessellate.
Using inspiration from the hexagon example, we can cut out a side of the parallelogram and move that portion to the opposite side. The cut can be a curve of any kind or it could be a jagged edge like I have done below. The figure tessellates the plane as shown in the last section of the diagram. We can place the figures side by side to fill up a 2D space. Think of it like putting a jigsaw puzzle together in a way.
