A remodeling project calls for sanding a chair with a disk sander. The sanding disk used on the sander has a radius of 4 inches. Find the area of the disk. Use 3.14 for \large \pi

Answers

Answer 1

Answer:

the area of the disk is 50.24 inches^2

Step-by-step explanation:

The computation of the area of the disk is as follows:

As we know that

The area of the circle is

= πr^2

= 3.14 × 4^2

= 3.14 × 16

= 50.24 inches ^2

hence, the area of the disk is 50.24 inches^2

10 cm
15 cm​

Answers

Answer:

≈ 189.3 cm²

Step-by-step explanation:

The shape is composed of a rectangle and a semicircle, then

area of rectangle = 15 × 10 = 150 cm²

The semicircle has a diameter of 10 cm , so radius = 10 ÷ 2 = 5 cm

area of semicircle = [tex]\frac{1}{2}[/tex] πr² = 0.5 × π × 5² = 12.5π cm²

area of shape = 150 + 12.5π ≈ 189.3 cm² ( to 1 dec. place )

Suppose you have a right triangle area marked in the ground with a base (8-h) meters long and a height h meters long. the hypotenuse is 6 meters long.


part a: what is the length of the height of the right triangle

Answers

Answer:

5.415m and 2.585m long

Step-by-step explanation:

For a right triangle

hyp^2 = opp^2 + adj^2 (Pythagoras theorem)

Given

hypotenuse = 6m

height(opposite) = h meters

Adjacent = (8-h)m

Substitute into the expression above;

6² = h²+(8-h)²

36 = h²+64-16h+h²

36 = 2h²-16h+64

2h²-16h+64-36 = 0

2h²-16h+28= 0

Divide through by 2

h²-8h+14 = 0

Using the general formula

h = 8±√8²-4(14)/2

h = 8±√64-56/2

h = 8±√8/2

h = 8±2.83/2

h = 8+2.83/2 and 8-2.83/2

h = 10.83/2 and 5.17/2

h = 5.415 and 2.585

hence the length of the height of the right triangle are 5.415m and 2.585m long

Together, teammates Pedro and Ricky got 2680 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each player have?

Answers

Answer:

Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478

Step-by-step explanation:

The computation is shown below:

Let us assume the ricky be x

So pedro be x + 276

Now the equation is

x + x + 276 = 2680

2x + 276 = 2680

2x = 2680 - 276

2x = 2404

x = 1,202

For Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478

A national park has two types of bears: Grizzly bears and black bears. A sciantist has reported 9 out of 12 bears she tagged are black bears. Show a model that compares the number of black bears tagged to the number of grizzly bear?

Answers

Answer:

Z = 0.75x + 0.25y

Step-by-step explanation:

Two bear types are identified :

Black bears and Grizzly bears

9 out of 12 = black bears ; Hence, 3 are grizzled

For the model:

For a bear population of Number x

Total bear population = black bear, x + grizzled bear, y

Proportion of black bear = 9/ 12 = 0.75

Grizzled bear = 1 - 0.75 = 0.25

Total bear population , Z= 0.75x + 0.25y

Hence,

Z = 0.75x + 0.25y

write an equation of the given line that passes through the given point and has the given slope m
(5,1);m=2

Answers

Answer:

y = 2x - 9

Step-by-step explanation:

Use slope intercept form, y = mx + b

Plug in the slope, x, and y, then solve for b:

y = mx + b

1 = 2(5) + b

1 = 10 + b

-9 = b

Then, plug in b and the slope into y = mx + b

y = mx + b

y = 2x - 9

So, the equation of the line is y = 2x - 9

Answer:

Step-by-step explanation:

y=mx+b, m=2

y=2x+b, using point (5,1)

1=2(5)+b

b=-9

Find the volume of triangular prism with the following dimensions. Round to the nearest whole number.
Triangle base= 7 ft.
triangle height= 4 ft
prism height: 8.5 ft

Answers

Answer:

124.0 ft^2

Step-by-step explanation:

let b = base of triangle = 7ft

h = height of triangle = 4ft

and

l = height of prism. = 8.5ft

We know,

volume of prism = area of triangular face of prizm × height of prizm

= 1/2 × b × h × l

= 1/2 × 7 × 4 × 8.5

= 7 × 2 × 8.5

= 14 × 8.5

= 124.0 ft^2

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 – 160x + 300. The variable x is the number of televisions sold.

If 150 televisions are sold, what is the profit?

$2,700
$6,000
$50,700
$51,300

Answers

Answer: $50,700 is the profit

If 150 televisions are sold, the profit is $50,700.

What is profit?

Profit is the total revenue less the total cost.

Profit = total revenue - total cost

What is profit?

Profit = (3x^2 + 180x) - (3x2 – 160x + 300)

Profit = (3 x 150^2 + 180 x 150) - (3 x 150^2 - 160x 150 + 300)

27,000 + 24,000 - 300
