Wich equation has a solution of 2/3 for n?
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).

How to solve this equation
0.1r-1=0.65
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

equally. How much soda did each child get?
Answer:
1.5
Step-by-step explanation:
6/4=3/2
3/2=1 1/2
or
1.5
Answer:
1.5
Step-by-step explanation:
Directions: find the equation of each line in standard form with the given properties:
1. Slope =3, y-intercept=1
2. Passing through (0,2), slope = -4
3. Passing through (-1,3) and (1,1)
4. Passing through (1,3), slope = 1/2
5. Passing through (1/2,1) and (4,2)
Answer:
Step-by-step explanation:
1) slope = 3 ; y-intercept = 1
y = mx + b
y = 3x + 1
0 = 3x + 1 -y
-1 = 3x - y
ANS: 3x - y = -1
2) Passing through (0,2), slope = -4
y - y₁ = m(x -x₁)
y - 2 = -4(x - 0)
y - 2 = -4x
4x + y - 2 = 0
Ans: 4x + y = 2
3)Passing through (-1,3) and (1,1)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{1-3}{1-[-1]}\\\\= \frac{-2}{1+1}\\\\= \frac{-2}{2}\\\\= - 1[/tex]
m= -1 ; (-1 , 3)
y - y₁ = m(x -x₁)
y - 3 = (-1)(x - [-1] )
y -3 = (-1)(x +1 )
y - 3 = -x - 1
x + y -3 = -1
x +y = -1 + 3
Ans: x + y = 2
4) Passing through (1,3), slope = 1/2
y - y₁ = m(x -x₁)
[tex]y - 3 = \frac{1}{2}(x - 1)\\\\y - 3 = \frac{1}{2}x - \frac{1}{2}\\\\[/tex]
Multiply the equation by 2
[tex]2*y - 2*3 = 2*\frac{1}{2}x - 2*\frac{1}{2}\\\\2y - 6 = x - 1\\[/tex]
2y - 6 +1 = x
2y - 5 = x
-5 = x - 2y
Ans: x - 2y = -5
5) Passing through (1/2,1) and (4,2)
Slope = [tex]\frac{2-1}{4-\frac{1}{2}}[/tex]
[tex]= \frac{1}{\frac{7}{2}}\\\\= \frac{2}{7}[/tex]
m = 2/7 ; (4 , 2)
y - y₁ = m(x -x₁)
[tex]y - 2 = \frac{2}{7}(x - 4)\\\\7y - 7*2 = 7*\frac{2}{7}(x - 4)\\\\7y - 14 = 2(x -4)\\\\7y - 14 = 2x - 8\\\\[/tex]
7y - 14 + 8 = 2x
7y - 6 = 2x
Ans: 2x - 7y = -6

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 :)
Hope this helps.

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.

Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
[Standard Form] 5x + 5y = 35
Step 2: Rewrite
Find slope-intercept form.
Subtract 5x on both sides: 5y = -5x + 35Divide 5 on both sides: y = -x + 716. Which statement best describes a margin of error?
A. the difference between a sample mean and a population proportion
B. the value of error between a sample mean and a population proportion
C. the difference between a sample mean and a population mean
D. the value of error between a sample statistic and an actual population parameter
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

Sum of the radius of the base and height of a cylinder is 21 cm and the curved surface area of the cylinder is 616 sq.cm,find the total surface area of the cylinder.
PLEASE HELP ME AS FAST AS POSSIBLE With a full process.
Answer:
925.04cm²
Step-by-step explanation:
Curved surface area of a cylinder = 2πrh
If the sum of the radius of the base and height of the cylinder is 21 cm, then;
r + h = 21
r = 21-h..... 1
The curved surface area is expressed according to the formula
CSA = 2πrh
Substitute the value of CSA given into the formula
616 = 2πrh ....2
Substitute equation 1 into 2;
]616 = 2π(21-h)h
616 = 2π(21h-h²)
Note that π = 3.14
616 = 42(3.14)h - 2(3.14)h²
616 = 131.88h - 6.28h²
98.09 = 21h - h²
h²-21h+98.09 = 0
h = 21±√21²-4(98.09)/2
h = 21±√441-392.36/2
h = 21±√48.64/2
h = 21±6/97/2
h = 21+6.97/2 and 21-6.97/2
h = 27.97/2 and 14.03/2
h = 13.985 and 7.015
Recall that r = 21-h
r = 21 - 13.985
Substitute r = 7.015 into the total surface area of the cylinder
The total surface area = 2πrh + 2πr²
The total surface area = 616 + 2(3.14)7.015²
The total surface area = 616 + 309.04
The total surface area = 925.04
Hence the total surface area of the cylinder is 925.04cm²
