surface area of 20,20,20

Answer:

[tex]15n=10\\\\n=\dfrac{10}{15}\\\\n=\dfrac{2}{3}[/tex]

Step-by-step explanation:

We need to find out of 4 options which equation has a solution of 2/3 for n.

Equation (1).

[tex]n-1=\dfrac{1}{3}\\\\n=\dfrac{1}{3}+1\\\\n=\dfrac{4}{3}[/tex]

Equation (2).

[tex]16n=24\\\\n=\dfrac{24}{16}\\\\n=\dfrac{3}{2}[/tex]

Equation (3).

[tex]15n=10\\\\n=\dfrac{10}{15}\\\\n=\dfrac{2}{3}[/tex]

Equation (4).

[tex]1\dfrac{1}{3}+n=3\\\\n=3-\dfrac{4}{3}\\\\n=\dfrac{5}{3}[/tex]

So, equation (3) has a value of n as 2/3. Hence, the correct option is (3).

Step-by-step explanation:

Six cans for $4

Answer:

50

Step-by-step explanation:

For starters, we make the following assumptions

Let the blue paint be represented by x

Let the white paint be represented by y

Now, forming an inequality equation from the question, we can say that

5x + 3y = 1

And from the second part, we are told that 40 gallons of light blue paints are needed.

If 5x + 3y = 1, then multiplying all by 40, we have

200x + 120y = 40

This means that 200 parts of blue paints is needed to be mixed with 120 parts of white paints to get the desired 40 gallons.

There are 4 parts in a gallon, so 200 parts = 200/4 gallons, = 50 gallons of blue paints

Answer:

r = 16.5

Step-by-step explanation:

Move the subtraction over to the over side first

0.1r - 1 = 0.65

It becomes addition on the right side

0.1r = 0.65 + 1

Move the multiplication over to the over side first

0.1r = 1.65

It becomes division on the right side

r = 1.65 / 0.1

r = 16.5

Answer:0.1r-1=0.65  (85% sure this is the answer

Answer:

4 hours.

Step-by-step explanation:

Okay, so they leave the same port. Since they are traveling at the same rate at 24mph, in one hour they will each be 24 miles from the port. Since they are going in opposite directions, they will be 24+24= 48 miles apart. Let another hour pass. They each go 24 more miles from the port so add another 48 to their distance apart. Now their distance is 96 miles apart. Let a third hour pass. Add 48. Now their distance is 144 miles apart. Let the fourth and final hour pass. Now they are 192 miles apart. So, it'll take them  4 hours to be 192 miles apart.

A visual way to interpret this problem is on a number line. We'll have steamer A going to the right of our origin 0 (the port) and steamer B going left. After one hour, steamer A will be at 24 on the number line, and steamer B will be at -24. the distance between these two points is 48. If you continue with the second, third and fourth hours they will each be going 24 points further from the origin, making their distance grow further and further apart by 48 points each hour.

I also completed the table for you :)

Answer: D. the value of error between a sample statistic and an actual population parameter

Step-by-step explanation:

In a study , the margin of error gives the amount of the random variation of the actual result from its estimation.

So, it is the value of error between a sample statistic( which is estimated population parameter until actual is known) and an actual population parameter.

Hence, the best statement to represent the margin of error :

D. the value of error between a sample statistic and an actual population parameter

The Equivalent fraction to 64 3/4 is 259/4.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

We have 64 3/4.

First change the mixed fraction into normal fraction as

64 3/4

= (4 x 64+3)/ 4

= 259/4

Required

Calculate the constant of proportionality.

Represent the required constant with k.

Such that:

[tex]k = \dfrac{y}{x}[/tex]

Pick any two corresponding values of x and y

[tex](x,y) = (1,40)[/tex]

This means that:

[tex]x = 1\ and\ y = 40[/tex]

[tex]k = \dfrac{y}{x}[/tex] becomes

Answer:

Solving the inequality [tex]m - 6 > 2[/tex] we get [tex]\mathbf{m> 8}[/tex]

The graph is shown in figure attached.

Step-by-step explanation:

We need to solve the inequality and graph the solution.

[tex]m - 6 > 2[/tex]

First solve the inequality

[tex]m - 6 > 2\\[/tex]

Adding 6 on both sides

[tex]m-6+6>2+6\\m>8[/tex]

Solving the inequality [tex]m - 6 > 2[/tex] we get [tex]\mathbf{m> 8}[/tex]

Now, we will plot m > 8 on the graph

The graph is shown in figure attached

There will be an open circle on 8 as (m > 8) and line moves on right sides of 8.
