In the figure below, what is m∠DAC? A. 47 B. 57 C. 90 D. 137

The polar equation will be  [tex]r=\dfrac{4}{1+cos\theta}[/tex]

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]

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

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

Either Cross Multiply or Turn into decimal to find the following answer.

For this question I suggest to turn into decimal.

Cross multiply would take longer time, but if you wish you could use both ways to check your answer.

I will be turn into decimal:

Main Fraction: 9/15 ⇒ 0.6

3/10 ⇒ 0.3

36/60 ⇒ 0.6

27/35 ⇒ 0.77142857142

20/30 ⇒ 0.66666666666

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

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:

Therefore, the number of pies Susan bought is;

∴ Half can be written as ½

If a whole number is being added to a fraction, we can combine them to convert the sum into mixed fraction.

Therefore, 5 ½ is the fraction of pies, Susan bought.

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.

Therefore, 11/2 is the fraction of pies, Susan bought.

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 results in getting 5 and 1/2 results in getting 0.5. Therefore,

Therefore, 5.5 is the decimal of pies, Susan bought.

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.

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:
