1. A cylindrical jar has a radius of 5 inches and a height of 9 inches. The jar is filled with marbles that have a volume of 20 in3. Use 3.14 for pi. Show work. Complete sentences.

a. What is the volume of the jar?










b. How many whole marbles can fit in the jar?

Answer:

8 dimes and 6 quarters

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

Work Shown:

d = number of dimes

q = number of quarters

d+q = 14 since this is his coin total; equation solves to d = 14-q

10d+25q = 230 which is the total value in cents

10(14-q)+25q = 230 .... apply substitution rule

140-10q+25q = 230

15q+140 = 230

15q = 230-140

15q = 90

q = 90/15

q = 6 = number of quarters

d = 14-q

d = 14-6

d = 8 = number of dimes

-----------------

Check:

8 dimes + 6 quarters = 14 coins

8 dimes = 8*10 = 80 cents

6 quarters = 6*25 = 150 cents

8 dimes + 6 quarters = 80 cents + 150 cents = 230 cents = $2.30

The answers have been confirmed.

Answer:

Hello, your

Step-by-step explanation:

For this particular problem (with units in mind), the formula for arc length is

Arc length

=

2

π

r

⋅

(

x

360

∘

)

,

Where

x

is the central angle measure and

r

is the radius of the circle.

You don't really have to work too hard to remember this formula. The arc length formula is easy to remember because it is just the circumference of the circle times the central angle over

360

∘

.

Anyway, let's continue with the problem. We are given that the central angle is

60

∘

, and that

r

, our radius, is

9

feet. So, let's plug that into our equation to find the arc length, in feet:

Arc length

=

2

π

r

⋅

(

x

360

∘

)

Arc length

=

2

π

(

9

)

⋅

(

60

∘

360

∘

)

Now, you might be tempted to plug this in your calculator, but let's simplify it a little bit more.

Arc length

=

2

π

(

9

)

⋅

(

60

∘

360

∘

)

Arc length

=

18

π

⋅

(

1

6

)

Arc length

=

3

π

feet

So, if you wanted an exact answer, it would be that the arc length is

3

π

feet

. If you wanted an approximate answer, then you can type

3

times

π

in your calculator to get a value of about

9.425

feet

as you alternative answer.

I hope that helps!

Don't stand in front of my back

Step-by-step explanation:

the general slope intercept form is

y = ax + b

a is the slope. it is expressed as ratio y change / x change when going from one point to another.

b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).

we get b by using the point coordinates in the equation and solve for b.

costs are on the y axis, miles are in the x axis.

so, what points do we see on the chart for the red taxi ?

let's start with the point right in the y-axis : (0, 2).

that gives us the y- intercept automatically.

and then let's pick e.g. the point, where both lines cross : (3, 8).

so, for the slope we look at the coordinate changes :

x changes by +3 (from 0 to 3).

y changes by +6 (from 2 to 8).

the slope is then 6/3 = 2.

and again, the y- intercept is +2.

therefore, the line equation is

y = 2x + 2

Answer: x=-12

Step-by-step explanation:

subtract 12 from both sides

3x=2x-12

subtract 2x from both sides

x=-12

Subtract 12 from both sides of the equation:

3x + 12 = 2x

3x + 12 - 12 = 2x - 12

Simplify:

3x = 2x - 12

Subtract 2x from both sides of the equation:

3x = 2x - 12

3x-2x = 2x  - 12-2x

Simplify:

combine like terms --> multiply by 1 --> combine like terms

x = -12 <-- ANSWER

Step-by-step explanation:

Assign variables to the integers

Let the larger integer be 'A' and the smaller 'b'

Write Equations based on the Question

Since the sum of the integers is 75, then A + b = 75 (eq

1)

Since the larger number is three times more than the smaller, then  A = 3b (eq2)

Combine the Equations and solve for variables

By substituting the value of A in eq1 into eq2

⇒ 3b + b = 75

          4b = 75

            b = ⁷⁵/₄ = 18.25

By substituting the value of b into eq1

⇒  A = 3(⁷⁵/₄)

    A = ²²⁵/₄ = 56.25

Check our Answer:

A + b = 56.25 + 18.75 = 75

39 is the answer

If $x$ is the larger integer, then the smaller integer is $x-3$. We find the sum and set it equal to 75:$$x+x-3=75\qquad\Rightarrow \qquad 2x=78\qquad\Rightarrow \qquad x=39$$The larger integer is $\boxed{39}$.

Step-by-step explanation:its the only ratio

Answer:

h(1.5) = 7.3 ft

h(10.3) = 24.9 ft

Step-by-step explanation:

Given the function h(d) = 2d + 4.3,

where:

h = height of the water in a fountain (in feet)

d = diameter of the pipe carrying the water (in inches)

Substitute the input value of d = 1.5, into the function:

h(1.5) = 2(1.5) + 4.3

h(1.5) = 3 + 4.3

h(1.5) = 7 feet

The height of the water in a fountain is 7 feet when the diameter of the pipe is 1.5 inches.

Substitute the input value of d = 10.3, into the function:

h(10.3) = 2(10.3) + 4.3

h(10.3) = 20.6 + 4.3

h(10.3) = 24.9 feet

The height of the water in a fountain is 24.9 feet when the diameter of the pipe is 10.3 inches.

The solutions to both functions show the relationship between the diameter of the pipe to the height of the water in a fountain.  The height of the water in fountain increases relative to the diameter of the pipe.  In other words, as the diameter or the size of the pipe increases or widens, the height of the water in a fountain also increases.  

Answer:

7 is isosceles so x= 55 bc the other angle is. 8 is isosceles so x= 68 and 9 is right angle all angles in a triangle add up to 180 so 180-90 /2 = 45 so x=45

To solve x, you need to isolate the variable with the following steps.

-10 + 3x > -4

3x > 6                  Add 10 to both sides.

x > 2

The solution is x > 2, or answer II and III.

Answer:

m = 1

Step-by-step explanation:

We can start by moving all the terms with m to one side by subtracting m from both sides(to cancel out):

11m + 13 = m + 23

-m            -m

10m + 13 = 23

Now, to single out the m term, we can subtract 13 from both sides:

10m + 13 = 23

         - 13    -13

10m = 10

To find the value of m, we can divide both sides by 10:

10m = 10

÷ 10  ÷10

m = 1

If there are a total of 120 donuts served 45 will be chocolate donuts.

A ratio is a comparison between two similar quantities in simplest form.

A ratio a : b can be written as a/b.

Given, A donut shop serves plain and chocolate donuts at a ratio of 5 to 3.

∴ Plain donuts : Chocolate donuts = 3 : 5.

If there are a total of 120 donuts served chocolate donuts will be,

= 3/(5 + 3)×120.

= (3/8)×120.

= 45 chocolate donuts.
