Answer:

90yrds^2

Step-by-step explanation:
First, let's find our area.
Area of a 2d rectangle is l(w). so 15(18) which in this case is 270ft.
Now that we have our area, we have to convert 270ft into yards.

A yard is equivalent to exactly 3ft. So let's use division to convert!
270/3 = 90.

Therefore, we need 90yrds^2 of carpet.

Answer:

2 or 3

Step-by-step explanation:

18 feet = 2 square yards

or if you

add 18 and 15 you get 33

33 feet = 3.6 square yards

a. To calculate the interest earned in 30 years, we can use the simple interest formula:

Simple interest = Principal * Rate * Time

Here, the principal (P) is $3,000, the rate (R) is 1.9%, and the time (T) is 30 years.

Simple interest = $3,000 * 0.019 * 30 = $1,710

Therefore, the customer will earn $1,710 in interest over 30 years.

b. To calculate the account balance after 30 years, we can add the interest earned to the principal:

Account balance = Principal + Interest

Account balance = $3,000 + $1,710 = $4,710

Therefore, the account balance will be $4,710 after 30 years.

Answer:

Step-by-step explanation:

To calculate markup by hand:

Determine your COGS (cost of goods sold). For example, $40.

Find your gross profit by subtracting the cost from the revenue. Our product sells for $50, so the profit is $10.

Divide profit by COGS. $10 / $40 = 0.25.

Express it as a percentage: 0.25 × 100 = 25%.

This is how to find markup... or simply use Omni's markup calculator!

The expression representing the discounted price of the item that is correct is C. The discounted price is p - 10%p, indicating that the retailer will lose 10% of his investment.

The discounted price is the selling price of an item less the discount.

The discount is usually stated in rates, showing the percentage of the reduction in the selling price.

Let the cost price = 100%

Markup = 20%

Selling price = 120% (100 + 20)

Discount = 25%

Discounted price (rate) = 120% x (1 - 25%)

= 90%

Difference between Discounted Price and the Cost Price = 10% (100% - 90%).

Thus, what the retailer loses is 10% of his investment cost, showing that Option C is correct.

no for the second

yes for the last one

Answer:

Yes

No

Yes

Step-by-step explanation:

The first is yes because each person may work for different periods of time, thus resulting in many different answers!
Second is no because there are a strict, unchanging amount of hours in a day. There would be no variety in each answer.

The last is yes because each month has different conditions in which rainbows could occur. Like in December youll get little to no rainbows because theres no rainfall. But in july you can get many rainbows!

Answer:

A) 132.97 cm²

Step-by-step explanation:

first, find the area of the rectangle.

8×7=56

then, find the area of the two quarter circles (ill just calculate for a half circle since bith quarters are the same)

the radius is 7, qnd the formula for a half circle is 1/2(πr2 )

so just plug in and solve

1/2(×7²)

π×7² is 153.86

153.86/2 is 76.93

then add those two areas together

76.93+56 = 132.96 (i used 3.14 for pi, but im assuming this calls for the actual pi to be used, so just round to 132.97)

Therefore, the table of ordered pairs that represents a proportional relationship is Table 2.

Step-by-step explanation:

The ratio of Y to X is 1/-1 = -1, 3/-3 = -1, and 5/-5 = -1. Since the ratio is constant (-1), Table 2 represents a proportional relationship.

Answer:

You cross multiply the numbers in each table. The table that has equal answers is proportional. In the table for choice B, you can tell the table is proportional since -1 x 3 = -3 x 1

Answer:

A. x > 14

Step-by-step explanation:

Answer: A

Step-by-step explanation:

First, its important to realize that x= the number of books the reads. We put a 10 in front of the x because for every 1 books she reads, she receives 10 points. If she needs 190 points total, and already has 50 points, we then need to find how many points she needs to get to 190. To find this, we subtract 50 from 190, and are left with 140 points remaining to reach 190.

10x+50>190

      -50  -50

10x>140

now that we know that 10x needs to be greater than 140, we can solve. We can divide both sides by 10 in order to find that x>14. She needs to read more than 14 books in order to earn the grand prize

[tex]\frac{10x > 140}{10}[/tex] = x>140

Answer: 75

Step-by-step explanation:

Add the values given in the table

16+15+20+14+15 = 80

Yellow happens 20 times out of the 80 times total.

The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%

If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.

Answer:

you have to divide the sequences

Step-by-step explanation:

53°

Angle X + Angle 2x + 21 = 180. [ LINEAR PAIR ]

Angle 3x + 21 = 180

Angle 3x = 180 - 21 [ Transposing 21 over to RHS ] ( addition becomes subtraction)

Angle 3x = 159

Angle x = 159 ÷ 3. [ Transposing 3 over to RHS ] ( Multiplication becomes divison)

Angle x = 53°

As you can see in the diagram, the triangular prism has the following faces:

1) Two triangular faces

2) Three rectangular faces.

Surface area is the SUM of the areas of all of the faces.

Let us find these faces one by one:

1.

As you know, the area of the triangle is:

[tex]\frac{1}{2}* base*height[/tex]

Since, the base = 6 inches, and height = 4 inches;

Therefore, The area of ONE triangle = (1/2) * 6 * 4 = 12 inches squared.

In triangular prism, there are two triangles, therefore,

Two triangular faces = 2 * 12 inches = 24 inches squared --- (A)

2.

Now let us find the areas of three rectangular faces...

Since, two of the three rectangular faces are the same, therefore, we would find the area of one rectangular face, and multiple the result with two to get the total area of two rectangular faces.

Area of one rectangular face = base * height.

Since, base = 0.5 inches, height = 5 inches, therefore,

Area of one rectangular face = 0.5 * 5 = 2.5 inches squared.

Now that we have one rectangular face, therefore,

Area of two rectangular faces  = 2 * 2.5 = 5 inches squared.

The area of the third rectangular base = 6 * 0.5 = 3 inches squared

Therefore,

The area of the three rectangular faces = 5 + 3 = 8 inches squared --- (B)

Now add both "area of two triangular faces(A)" and "area of three rectangular faces(B)" to get the final surface area of the triangular prism.

Surface Area of the triangular prism = Area of Two Triangular faces + Area of Three Rectangular faces

Surface Area = 24 + 8 = 32 inches squared

The surface area of the triangular prism = 32 inches squared.

Answer:

1634.77

Step-by-step explanation:

2πr= circumference

80.89=2πr

80.89/ πr= r

r= 12.87

area= πr^2

area= 12.87 π^2

area= 1634.77

Answer:

520.89 cm²

Step-by-step explanation:  

IN GIVEN QUESTION

The hubcap of the tire's circumference is 80.89 centimetres.

We must determine the radius of this hub cap, which we can do by using the circumference method to determine its area

now :

2πr = 80.89 cm

r = 80.89/ 2× 3.14

r = 12. 88 cm ( approx)

Area of hub cap = πr²

Area = 3.14 ×12.88² = 520.89 cm²

Answer:

Step-by-step explanation:

A=2πd
