Circle A has a diameter of approximately 20 inches and an area of approximately an area of 300 in² Circle B has a diameter of approximately 60 inches Which of these could be the area of circle B? A. About 100 in^2 B. About 300 in^2 C. About 900 in^2 D. About 2700 in^2

Answers

Answer 1

Answer:

D. About 2700 in^2

Step-by-step explanation:

The area of a circle A = πd²/4 where d = diameter of circle.

A/d² = π/4 = k the proportionality constant.

So, A₁/d₁² = A₂/d₂² Now for circle A, Area = A₁ = 300 in² and diameter = d₁ = 20 inches. For circle B, Area = A₂ = unknown and diameter = d₂ = 60 inches.

So, we have

A₁/d₁² = A₂/d₂²

A₂ = A₁d₂²/d₁²

A₂ = A₁(d₂/d₁)²

substituting the values of the variables, we have

A₂ = 300 in²(60 in/20 in)²

A₂ = 300 in²(3)²

A₂ = 300 in²(9)

A₂ = 2700 in²

So, the area of circle B is about 2700 in²

Find the area of the triangle

Answers

Answer:

The area of the triangle WYX  = [tex]\frac{35}{2}[/tex] = 17[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The area of the triangle WYX  is [tex]\frac{1}{2}[/tex]*b*h

We need to find base (b) and height (h)

By counting from the drawing, the base which is horizontal is 7 and the height which is vertical is 5

The area of the triangle WYX  is [tex]\frac{1}{2}[/tex]*b*h

The area of the triangle WYX  = [tex]\frac{1}{2}[/tex]*7*5 = [tex]\frac{35}{2}[/tex] = 17[tex]\frac{1}{2}[/tex]

so answer  is  6  as you cannot buy half books...

Answer: 6 hard cover books

Step-by-step explanation:

$155 x 8 =1,240

$188 x 6 = 1,128 which is as close as you can get without going over

Alyssa used a scale in which 1 inch represents 100 feet. If the actual landmark has a height of 508 feet, find the height of Alyssa's model in inches.

Answers

Answer:

5.08 inches

Step-by-step explanation:

Alyssa used a scale in which 1 inch represents 100 feet. If the actual landmark has a height of 508 feet, find the height of Alyssa's model in inches.

The scale =

1 inch = 100 feet

100 feet = 1 inch

508 feet = x inches

Cross Multiply

100 × x = 508 × 1

x = 508 × 1/100

x = 5.08 inches

The height of the model is 5.08 inches

If it takes 80 seconds to complete a transaction, how many products are being purchased?​ If it takes 80 seconds to complete a transaction, how many products are being purchased? If it takes 48 seconds to complete a transaction, how many products are being purchased?​

Answers

Answer:

a) 4 products

b) 10 products

Step-by-step explanation:

When completing an online shopping transaction, a typical shopper takes 5 seconds to select each product and another 28 seconds to complete the check-out process.

For 1 product, the total time =

5 seconds + 28 seconds = 33 second.

We can derive an equation

Total time of transaction = 5x + 28

Where x is the number of products you are selecting

a) If it takes 48 seconds to complete a transaction, how many products are being purchased?

Total time = 5x + 28

48s = 5x + 28

5x = 48 - 28

5x = 20

x = 20/5

x = 4 items

b) If it takes 80 seconds to complete a transaction, how many products are being purchased?

Total time = 5x + 28

80s = 5x + 28

5x = 80 - 28

5x = 52

x = 52/5

x = 10 items

In whole number = 10 items

Answers

Answer: 4 seeds will left over.

Step-by-step explanation:

Total sunflower seeds = 1354

Number of people shared sunflower  seeds equally = 6

By division operation,

Number of seeds each people will get = (Total sunflower  seeds) ÷ (Number of people shared seeds equally)

[tex]= (1354) \div (6)[/tex]

[tex]=225\dfrac{4}{6}[/tex]
