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*

Answers

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

Select each equation that matches the description. You will not use all the equations.
Option 1: b-0.15b=0.85b

Option 2: 2n+3n=5n

Option 3: b+0.15b=0.85b

Option 4: x+0.15x=1.15x

Option 5: 2n-3n=5n

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.

Answers

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 answer is 10.

You have to add 24 with 26 with 30 then divide that by 8 and which will get you ten. Ten is how many packages you Mr. Jackson would need for his 2nd, 3rd, and 4th grade classes

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?

Answers

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

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

Answers

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]

Please help! If you help with this please do my other questions!! (They are very similar!)

Answers

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
