Answer:
Step-by-step explanation:
Amount with Jeremiah = $7
Cost of Sprite = $1.50
Amount remaining = Amount with Jeremiah - Cost of Sprite
= $7 - $1.50
= $5.50
Gummy worms cost = $0.27 each
Number of gummy worms he can purchase = $5.50 / $0.27
= 20.37
Jeremiah can buy as many as 20 packs of gummy worms

2.Jasmine drives every morning to her office that is 12 miles from her home.
If Jasmine's average driving speed is s mph, how many minutes does it take her to reach the office
3.Jasmine drives every morning to her office that is 12 miles from her home.
Suppose Jasmine drives from home to the office in 20 minutes. Use this information and part (b) to write an equation.
4.Jasmine drives every morning to her office that is 12 miles from her home.
* What is Jasmine's driving speed in mph?
Solve the equation you created in part (c) to answer the question.
Answer:
1. Her time in minutes is 720/s minutes
2. Given her time to be 20 minutes, her speed is 36 mph
Step-by-step explanation:
Mathematically,
Distance = speed * time
In this question, we want to calculate time;
So time = distance/speed
times = 12 miles/s mph = 12/s hours
Now we want our answer in minutes
Kindly recall that 60 minutes = 1 hour
So 12/s hours will be 12/s * 60 = 720/s minutes
2. Since she drives from home to the office in in 20 minutes, we want to calculate her speed in mph
From the time calculated above i.e 720/s
We can equate 20 = 720/s
20s = 720
s = 720/20
s = 36 mph

Given:
The expression is [tex]\dfrac{7}{\frac{5}{8}}[/tex].
To find:
The shows the correct way to use the rule ""multiply by the reciprocal"" for the given expression.
Solution:
According to the rule "multiply by the reciprocal", if a,b,c,d are four number, then
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
We have,
[tex]\dfrac{7}{\frac{5}{8}}[/tex]
It can be written as
[tex]\dfrac{7}{\frac{5}{8}}=\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}[/tex]
Using the rule "multiply by the reciprocal", we get
[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{7}{1}\times \dfrac{8}{5}[/tex]
[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{7\times 8}{1\times 5}[/tex]
[tex]\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{56}{5}[/tex]
Therefore, the correct option is D.

You are a travel agent. A customer requires a hotel
reservation for four nights. You are considering two
hotels. The first usually charges $168 per night, including
all taxes and fees, but will give a discount of $40 per
night. The second charges $185 per night, including all
taxes and fees, and will offer one night for free.
O $504
O $512
O $555
$580
O $672
Answer:
$512
Step-by-step explanation:
Charges at the first hotel are ...
4(168 -40) = 4(128) = 512
Charges at the second hotel are ...
(4-1)(185) = 3(185) = 555
The first hotel offers the better rate: $512 for four nights.

At what rate is Riya applying mulch in m 3 m 2 m 2 m 3 start fraction, start text, m, end text, cubed, divided by, start text, m, end text, squared, end fraction?
Answer:
0.25m³
Step-by-step explanation:
If Riya is applying mulch to her garden. She applies it at a rate of 250,000 cm³ for every m², to know how much she is applying in m³ for every m², we will make use of the conversion formula:
100cm = 1m
1cm = 1/100m
1cm = 0.01m
250,000cm³ = 250,000 × 1cm×1cm×1cm
250,000cm³ = 250,000×0.01×0.01×0.01
= 250,000×0.000001
= 0.25m³
Hence Riya is applying at 0.25m³ per m²
Answer:
0.25m³ / m²
Step-by-step explanation:
Given that:
Rate of application = 250,000 cm³ of mulch per m²
The rate of application in m³ per m² can be calculated thus :
Converting 250,000 cm³ to m³
1cm = 1/100 = 0.01m = 1 * 10^-2 m
Hence
1cm³ = (1 * 10^-2 m)³ = 1 × 10^-6 m³
Hence,
250,000cm³ = (250,000 * 10^-6)m³ = 0.25m³
Hence, rate of application in m³ / m² equals
0.25m³ / m²
Robert earned $10, which was 4 less than twice what Eric earned. How much money
did Eric earn?
In a complete sentence, state the correct equation for the scenario.
Identify and define your variable. Then, using the correct vocabulary, and math
process, explain how to accurately solve the problem. Lastly, In a complete sentence
define your answer.
Answer:
Eric earnings equals $7
Step-by-step explanation:
Let amount earned by Robert = $10
Amount earned by Eric = $x
Robert earnings = 2x - 4
2x - 4 = 10
2x = 10 + 4
2x = 14
Divide both sides by 2
x = 14 / 2
= 7
x = 7
Eric earns $x which is equal to $7

Step-by-step explanation:
AFE-BFD<---------------
Hello.
Vertical angles are two sets of angles congruent to each other, both on opposite sides, but measure the same.
In the diagram shown, both angles ∠BFC and ∠EFA are identical, it seems mirrored, thus they are vertical angles.
The correct answer is B.
- 10x - y = 27
- 4x - y = 9
Find the solution of the system equation.
Step-by-step explanation:
-10x - y = 27 ...1
-4x - y = 9 ...2
...1 - ...2
-10x -y - (-4x - y) = 27 - 9
-10x -y +4x + y = 18
-10x + 4x = 18
-6x = 18
x = 18/(-6)
= -3
Answer:
x = - 3, y = 3
Step-by-step explanation:
Given the 2 equations
- 10x - y = 27 → (1)
- 4x - y = 9 → (2)
Multiplying (1) by - 1 and adding to (2) eliminates the term in y
10x + y = - 27 → (3)
Add (2) and (3) term by term to eliminate y
6x = - 18 ( divide both sides by 6 )
x = - 3
Substitute x = - 3 into either of the 2 equations and solve for y
Substituting into (2)
- 4(- 3) - y = 9
12 - y = 9 ( subtract 12 from both sides )
- y = - 3 ( multiply both sides by - 1 )
y = 3
Solution is x = - 3, y = 3

Which statement describes the transformation that would map figure QRST to figure Q'R'S'T' on the grid above?
(x,y) → (-x,y - 9) is the correct transformation for the given graph so option (A) will be correct.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given the quadrilateral QRST not if we look at Q'R'S'T' it is 9 units downward so it means there will be 9 units decrement in y units.
So y → y - 9
Now,
Q'R'S'T' is as far from the x-axis as QRST but on the negative x-axis.
So,
x → -x
Hence "(x,y) → (-x,y - 9) is the correct transformation for the given graph".
