Answer:

97.6 in^3

Step-by-step explanation:

find the volume of the cylinder and then find the volume of the cone. the formula for the volume of the cylinder is pi*r^2*h. the formula for the volume of the cone is 1/3*pi*r^2*h. r=d/2=4/2=2, h(cylinder)=8, h(cone)=0.7. now just plug these values into the formulas.

cylinder: pi*2^2*8=100.531

cone: 1/3*pi*2^2*0.7=2.932

cylinder-cone= 100.531-2.932=97.599. round to the nearest tenth to get 97.6

Answer: Mr. Smith makes 14,400, Mr. Kelly makes 9,600

Step-by-step explanation: First add the ratio together. 3+2=5.

Then divide 24,000 into five parts, 24,000/5 = 4,800.

After getting 4,800, multiply 4,800 by 3 to get Mr. Smith's portion of the money received. 4,800 x 3 = 14,000.

And you can do the same for Mr. Kelly but use 2 instead of a 3.

4,800 x 2 = 9,600

To check your work you can add the two answers together

9,600 + 14,400 = 24,000.

Answer:

a =4 and b= 3

Step-by-step explanation:

Stare at it for a bit. You have the squre of x, then(ignoring the minus sign) 2 times x times 4. What's left is the square of 4, which is 16; you have 13, you are 3 short. Let's add them to both sides:

[tex]x^2-8x+13+3=3 \rightarrow x^2-8x+16 = 3\\(x-4)^2 = 3[/tex]

so a =4 and b= 3

y-intercept: 3/7

Step-by-step explanation:

Our equation: y = mx + b

Given equation: y = 6x + 3/7

Now, let's compare:

y = mx + b = y = 6x + 3/7

We can tell that the y intercept is b, which is 3/7

Answer: False. 21 Shelves.

Step-by-step explanation:

First, 12 x 31= 372

This indicates that there are 372 books.

Then, 372 ÷ 18= 20.6666666667

Since we have a decimal that is above 4 we round up.

This leaves 21 shelves needed for all the books o fit on a shelf.

= > (122°F − 32) × 5/9

= > 50°C...ans

The value of 122°F in °C is 50°C

Temperature is the degree of hotness or coldness in a place. There are different temperature scales such as Celsius, Fahrenheit etc.

To convert from Fahrenheit to Celsius, use:

C = (F - 32) * 5/9

Given that F = 122, hence:

C = (122 - 32) * 5/9 = 50°

The value of 122°F in °C is 50°C

Answer:

x =2.5 and y=5.5

Step-by-step explanation:

using elimination method

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The point of intersection is (2.4, 5.5).

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 5 is an equation.

3x + 4y = 5 is an equation.

We have,

Two equations.

3x - y = 2 ____(1)

x + 3y = 19 _____(2)

The point of intersection can be calculated as,

From (1) we get,

3x = 2 + y

x = (2 + y) / 3 _____(3)

From (2) we get,

x = 19 - 3y ______(4)

From (3) and (4) we get,

(2 + y)/3 = 19 - 3y

2 + y = 57 - 9y

y + 9y = 57 - 2

10y = 55

y = 55/10

y = 5.5

Now,

From (3) we get,

x = 19 - 3y

x = 19 - 3 x 5.5

x = 19 - 16.6

x = 2.4

Thus,

The point of intersection is (2.4, 5.5).

Answer:

9

Step-by-step explanation:

To calculate the value of x we must first understand the total value of all angles in a triangle.

Sum of all angles in a triangle = 180 degrees

That said, we need to write an equation for the total number of degrees in the triangle and solve for x

This will be as follows:

(13x+2)+(5x-7)+(3x-4)=180

The we combine the like terms. This will be as follows:

(13x+5x+3x)+(2-7-4)=180

Simplify further to get

21x-9=180

Simplify further by collecting all like terms on one side of the equal. This will entail the addition of 9 on each side of the equal sign as follows:

21x-9+9=180+9

you will find 21x=189

Simplify further by dividing both sides of the equal sign by 21 to solve for x

21x/21=189/21

Therefore x=9

Step-by-step explanation:

as x intercepts are -8 and 72 we realize that f(x)=a(x+8)(x-72)

we know that f(62)=-490 so a= -0.7

so f(x)= -0.7(x+8)(x-72)

From the given figure ,

RECA is a quadrilateral

RC divides it into two parts

From the triangles , ∆REC and ∆RAC

RE = RA (Given)

angle CRE = angle CRA (Given)

RC = RC (Common side)

Therefore, ∆REC is Congruent to ∆RAC

∆REC =~ ∆RAC by SAS Property

⇛CE = CA (Congruent parts in a congruent triangles)

Hence , Proved

Answer:

k = 5

Step-by-step explanation:

The straight angle is 180º

The right angle is 90º

Therefor

(8k + 1) + 90 + 49 = 180

combine like terms

8k + 140 = 180

Subtract 140 from both sides

8k = 40

Divide both sides by 8
