Please help i give brainliest, show the work though. Susan is buying 5 and a half pies from the market. Write this amount as a mixed number, improper fraction, decimal and percent.
Answer: 5 1/2 pies as a mixed number, 11/2 as an improper fraction, 5.5 as a decimal, 550 as a percent
Step-by-step explanation:
2x5+1 11
-----------= -----
2 2
The fraction 5 1/2 is equal to 5, plus 1 divided by 2 which is equal to 5, plus 0.5 which is equal to 5.5 in decimal
5.5 x 100 = 550 percent
Given statement: Susan is buying 5 and a half pies from the market.
We already know:
The word "and" means "in addition to", which means addition (+)Therefore, the number of pies Susan bought is;
⇒ 5 and a half pies⇒ 5 + half pies∴ Half can be written as ½
⇒ 5 + ½If a whole number is being added to a fraction, we can combine them to convert the sum into mixed fraction.
⇒ 5 + ½⇒ 5 ½Therefore, 5 ½ is the fraction of pies, Susan bought.
Improper fraction:Given statement: Susan is buying 5 and a half pies from the market.
In mixed fraction: Susan is buying 5 ½ pies from the market.
To convert the mixed fraction of pies into improper fraction, simply multiply the whole number by the denominator and add the numerator to the product of the whole number and the denominator. The denominator in the mixed fraction will remain the same in the denominator.
⇒ 5 ½⇒ [(5 × 2) + 1]/2⇒ [(10) + 1]/2⇒ [11]/2 = 11/2Therefore, 11/2 is the fraction of pies, Susan bought.
Decimal:Given statement: Susan is buying 5 and a half pies from the market.
In improper fraction: Susan is buying 11/2 pies from the market.
Clearly, we can rewrite 11/2 as;
⇒ 10/2 + 1/210/2 results in getting 5 and 1/2 results in getting 0.5. Therefore,
⇒ 5 + 0.5⇒ 5.5Therefore, 5.5 is the decimal of pies, Susan bought.
Percent:Given statement: Susan is buying 5 and a half pies from the market.
In decimal: Susan is buying 5.5 pies from the market.
Simply multiply the decimal by 100 to determine the percentage of pies bought by Susan.
⇒ 5.5 pies = 5.5 x 100% = 550%
Therefore, 550% is the percent of pies, Susan bought.

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

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
(see screenshot)

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
