Answer:
15d=165
Step-by-step explanation:
15 dollars per dough (d)= 165 dollars
Hope this helps! ;-)
~Master Chief
Let's solve this problem step by step:
So we know that Isaac sold 'x' number of tubs of dough
⇒ and that each tub of dough is worth 15 dollars
⇒ means he made '[tex]15*x'[/tex] dollars from selling 'x' tubs of dough
⇒ coincidently, we know that he made a total of $165
⇒ So the equation is: [tex]15x = 165[/tex]
Answer: 15x = 165
Hope that helps!

27. Find a polar equation of the conic with focus at the pole that has the given eccentricity and equation of directrix.
e=\frac{4}{3}, r \cos \theta=-3
The polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]
What is the polar equation?A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.
From the equation, we are told that
The Eccentricity: e = 1
The Directrix is y = 4
Generally, the polar equation for e = 1 and y = + c is mathematically represented as
[tex]r =\dfrac{e\times c}{1+ecos\theta}[/tex]
[tex]r =\dfrac{1\times 4}{1+1\times cos\theta}[/tex]
[tex]r=\dfrac{4}{1+cos\theta}[/tex]
Therefore the polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]

A parallelogram has an area of 120 square feet and a height of 6 feet.
What is the length of the base of the parallelogram?
Enter your answer in the box.
*box*
Answer:
20 feet
Step-by-step explanation:
1. We know from here that A = bh (Area = Base x Height).
We are given:
A = 120 ft^2
h = 6 ft
b = ?
2. Let's rearrange our formula (A = bh) so that we find what "b" equals."
Our new formula will be: b = A/h (base = Area / height).
3. Let's apply it to the question and do the required math!
b = A/h
b = 120/6
b = 20 ft
Answer:
b = 20 ft
Step-by-step explanation:
The area of a parallelogram is given by:
A = b*h
where,
A: area = 120 ft^2
b: base = ?
h: height = 6 ft
From the equation for A, solve for b, replace the values of A and h and simplify:
b = A/h
b = 120ft^2/6ft
b = 20ft
Hence, the length of the base of the parallelogram is 20 ft

First Question: Screenshot the following image and attach a photo after you dilate by a scale factor of 2.
Second Question: Screenshot the following image and attach a photo after you dilate by a scale factor of 1/3.
Please help! If you help with this please do my other questions!! (They are very similar!)
Answer: See in the explanation, screenshot attached
Step-by-step explanation:
SQUARE QRTS
Step 1: Label all of the coordinates
Step 2: Find the coordinates of the points
Q: (-2, 1)
R: (2, 1)
T: (-2, -2)
S: (2, -2)
Step 3: Know what it means to dilate
To dilate is to make a shape bigger or smaller. For example, when it says to dilate by a scale factor of 2, you multiply each coordinate by 2 to get coordinate pairs that are twice the original amount (in this case you make it bigger). However, if it says to dilate by a scale factor of a fraction, for example 1/2, you'd multiply the coordinates by 1/2 and hence make it smaller (1/2 its size).
Step 4: Dilate by a scale factor of 2--multiply by 2
*x stands for the x coordinate, and y stands for the y coordinate*
Q: -2, 1
x: -2x2= -4
y: 1x2= 2
[Dilated] Q: -4, 2
R: 2, 1
x :2x2= 4
y: 1x2= 2
[Dilated] R: 4, 2
T: -2, -2
x: -2x2= -4
y: -2x2=-4
[Dilated] T: -4, -4
S: 2, -2
x: 2x2= 4
y: -2x2= -4
[Dilated] S: 4, -4
Step 5: Plot the new pairs
(See screenshot)
SQUARE ABCD
Step 1: Label all the coordinates
Step 2: Find the coordinate pairs of the points
A: -3, 3
B: 3, 3
C: 3, -3
D: -3, -3
Step 3: Remember what it means to dilate
(See 1st explanation)
Step 4: Dilate by a scale factor of 1/3
**Since 1/3 is a fraction, we are making the square smaller, or making it ⅓ of its original size. You will see that the numbers of the coordinates get smaller once you dilate them.**
A: -3, 3
x: -3x1/3= -1
y: 3x1/3= 1
[Dilated] A: -1, 1
B: 3, 3
x: 3x1/3 = 1
y: 3x1/3= 1
[Dilated] B; 1, 1
C: 3, -3
x: 3x1/3= 1
y: -3x1/3= -1
[Dilated] C: 1, -1
D: -3, -3
x: -3x1/3= -1
y: -3x1/3= -1
[Dilated] D: -1, -1
Step 5: Plot the new pairs

the shoes department is offering a sale of 15% off all shoes. if mrs. jefferey saved $12.30, how much were the shoes full price?
Answer: $82
Step-by-step explanation:
F - .15F = 12.30
F = 12.3/.85 =$14.47 for full shoe price rounded down a fraction of a cent
Full Price minus 15% discount = $12.30
F - 0.15F = 12.30
F(1-0.15) = 12.30
0.85F = 12.30
Overall answer --->F = 12.30/.85 = 14.47058824

Ricardo paid for 3 pounds of oranges with a $10 bill. He got back $8.20. What was the cost of 1 pound of oranges?
Answer:
6 cents
Step-by-step explanation:
10 - 8.20 = 1.8
1.8 / 3 = 0.6
Hope this helps you :D
Answer: $0.60
Step-by-step explanation:
Facts
got 3 lbs of oranges
paid with $10, got 8.20 in change.
Step 1: Find how much the 3lbs of oranges actually cost (actual total)
10-8.20= 1.8
Step 2: Find the unit rate (cost per lb)
Cost per lb. Divide the cost by the number of pounds, as shown:
1.8/3= 0.6
Step 3: Checks
[hypothetically], each pound costs 0.60.
Buying 3 pounds of oranges, multiply 0.6x3= 1.8.
Now, you pay with $10.
To find how much change you get, subtract 10-1.8= 8.20
These computations are correct, and the resulting facts match those given in the question. This is how I double check the answer is accurate.
Hence, each pound costs $0.60, or 60 cents.
Hope this helps :)) brainiest would be appreciated :D
1. How can you describe the likelihood of an event?
Answer:
It could be the probability or this for an example: 1/2 = an equal chance of getting 1 or 2, 3/4 = likely, 1/4 is going to be unlikely since you have a lower chance of something, and 4/4 = 1 = a certain chance of something happening.
Step-by-step explanation:
well it could be the probability.
Mr. Jackson is ordering kazoos for his second, third, and fourth grade music classes.
The kazoos come in boxes of 8. There are 26 second graders, 24 third graders, and 30 fourth graders.
How many boxes of kazoos does Mr. Jackson need to order so that every student will receive a kazoo?
Enter your answer in the box.
Answer:
The boxes of kazoos Mr. Jackson needs to order (26 + 24 + 30) ÷ 8.
We have given that,
There are 26-second graders, 24 third graders, and 30 fourth graders.
What is the expression?
An expression, in math, is a sentence with a minimum of two numbers and at least one math operation contain in it.
The amount of kazoos needed is 1 for every student
26 + 24 + 30
Since 8 come in each box, you divide by 8
To get your answer of (26 + 24 + 30) ÷ 8.

The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on visual inspection of the dot plots, which of the following groups appears to have the longer average forearm length?
A. Group B, because a child in the group has the least forearm length of 11 inches
B. Group A, because three children in the group have the least forearm length of 11 inches
C. Group B, because four children have a forearm length longer than 13 inches
D. Group A, because no child in the group has a forearm length longer than 13 inches
So, The dots represent the children.
And the numbers represent the length in.
I wouldnt say its D.
I would say its C. Group B, because 4 kids have forearm length longer then 13 in.
