Answer:

4187 ft³

Step-by-step explanation:

[tex]\frac{4}{3}[/tex]πr³

π = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

Radius = 20 / 2 = 10 feet

(4/3) x 3.14 x 10³ = 4187 ft³

Answer:

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

It can be written as

f(w) =  (w+10) w.

Step-by-step explanation:

Let the width of the rectangular blanket be given by w and the length be given by l. According to the given condition length = 10+ width

Area of the rectangular blanket= length * width

A= l*w    ( as l= w+10)

A = (w+10) w

A= w²+ 10w

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

It can be written as

f(w) =  (w+10) w.

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

The area of the rectangle is the product of the length and width of a rectangle.

Area of rectangle = L × W

Let the width of the rectangular blanket be given as w and the length be given by l.

The length is given as 10 inches greater than its width

length = 10+ width

Area of the rectangular blanket= length × width

A= l × w    

also, A = (w+10) w

A= w²+ 10w

Therefore, the function f(w) = w²+ 10w gives the area of the rectangular blanket.

Answer:

175 in³

Step-by-step explanation:

First the area of the triangle:

S: ½a×b×SinC

½×7in×10in×Sin90°===> 35in²

and now the volume

35 in²×5 in=175 in³

Answer:

Mass = density * volume

Mass = 6 g/cm^3 / 34 cm^3

Mass = 0.1764705882 grams

Step-by-step explanation:

Answer:

204 g

Step-by-step explanation:

*I thinks you have made a mistake with the unit of the volume*

Density = mass / volume

Mass = volume * density

mass = 6 * 34

mass =204 g

This is an exponential expression with 10 as the base and 4 as the exponent.

=============================================

Explanation:

We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.

The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.

Side note: 10^4 = 10,000 = ten thousand

Answer:

In a deck of cards, there are 6 faced cards. So, the probability of drawing a faced card is 6 out of 52 cards. Thus, the probability of drawing a face card from a deck of cards is 6/52 = 3/26.

Step-by-step explanation:

Answer:

4/13

Step-by-step explanation:

There are 4 10 cards.

There are 12 face cards.

Probability of both:

4/52 + 12/52 = 16/52 = 4/13

Answer:

1/2 and 9/14

Step-by-step explanation:

Let the first fraction be 1/2

Let the second fraction be x

1/2 + x= 8/7

x= 8/7-1/3

= 16-7/14

= 9/14

Hence the two numbers are 1/2 and 9/14

Answer:

Step-by-step explanation:

Explanation:

Recall that the general point-slope form is [tex]y - y_1 = m(x - x_1)[/tex] where m is the slope and [tex](x_1, y_1)[/tex] is the point the line goes through. We see that the 2 and the m match up, so m = 2 is the slope.

Side note: We can rewrite that given equation into y - (-5) = 2(x - (-1)) to see that the line goes through the point (-1, -5)

Answer:

C: 2

Step-by-step explanation:

y + 5 = 2x + 2 (distribute 2)

y = 2x -3 (subtract 5 from both sides)

2x means: slope times x

Answer:

Width of the rectangle is 8 feet

Length of the rectangle is  13 feet

Step-by-step explanation:

Complete question -

The length of a rectangular garden is three feet less than twice its width. If the perimeter of the garden is 42 feet, what is its length?

Solution

Let the width  of the  rectangle be X feet

Length of the rectangle would be 2X -3  feet

Perimeter of the rectangle is 2 (length + breadth)

Substituting the given values, we get -

Perimeter =  2 (length + breadth)

[tex]42 = 2 [(2X-3) + X]\\42 = 4X - 6 + 2X\\48 = 6X\\X = 8[/tex]

Width of the rectangle is 8 feet

Length of the rectangle is  [tex]2*8 -3 = 16-3 = 13[/tex] feet

Answer:

Step-by-step explanation:

Expand the following:

(x + 1) (x + 8) = (x) (x) + (x) (8) + (1) (x) + (1) (8):

x x + 8 x + x + 8

x x = x^2:

x^2 + 8 x + x + 8

Grouping like terms, x^2 + 8 x + x + 8 = x^2 + (8 x + x) + 8:

x^2 + (8 x + x) + 8

8 x + x = 9 x:
