Select all ratios equivalent to 3:2.

Submit
Answer:
15:10, 18:12
Step-by-step explanation:
Technically speaking, the first value, 3, is 1.5x greater than the second value, 2.
So, in all other ratios, the first value should be 1.5x greater than the second.
We can check by dividing the first number of each ratio by 3, and if we multiply 2 by the quotient, it should be 1.5x smaller
___________________________________________________________
10:1, Incorrect
This is incorrect because the first value is not 1.5x greater than the second. It is 10x greater
10/3 = 3.333....
1 x 3.33... = 3.3333....
3.3333.... x 1.5 ≠ 10
15:10, Correct
This is correct because the first number is 1.5x greater than the second.
15/3 = 5
5 x 2 = 10
10 x 1.5 = 15
18:12, Correct
This is correct because the first number is 1.5x greater than the second.
18/3 = 6
6 x 2 = 12
12 x 1.5 = 18

Write the equation of the line that passes through the given points (9,4) and (2,13)
Answer:
y = -9 / 7x + 109 / 7
Step-by-step explanation:
To find the equation of any line, you must find the slope and y-intercept (when writing in slope-intercept form). In this case, we can find both of these values by using the two coordinate pairs that are given:
Slope - the change in y over the change in x
9 / -7 = -9 / 7slope = -9 / 7y-intercept - when x = 0Right now, since we have the slope, we know the equation will look like this: y = -9 / 7x + b, b is what we are trying to find, the y-intercept. To find b, we can substitute a given coordinate pair that we know will fit this line and then solve:
13 = -9 / 7 x 2 + b13 = -18 / 7 + b91 / 7 + 18 / 7 = b109 / 7 = bAfter finding both the slope and y-intercept, we can now combine them together to form the equation of the line:
y = -9 / 7x + 109 / 7
Hope this helps!!

Answer: table 1 is 35 and table 2 is 1.301
Step-by-step explanation:
write the equation of the line that passes through the given point and has the given slope write all final answers in slope intercept form (3,-8); slope = -3
Step-by-step explanation:
the general slope intercept form is
y = ax + b
a is the slope.
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 :
-8 = -3×3 + b = -9 + b
1 = b
so, the full line equation is
y = -3x + 1

The volume of a cylinder closed at the one end is 1056cm cube. If its height is 21cm, and the radius is 4, find the total surface area
Answer:
578 cm^2
Step-by-step explanation:
The surface area is given by one circle of radius 4 (the other is missing!), plus a "rectangle" (the lateral surface) of sides 21 and [tex]2\pi \times 4[/tex] (the length of the circumference at the base). Adding them up we get:[tex]\pi \times4^2 + 21\times 2\pi\times4 = 184\pi \approx 578 cm^2[/tex]

Both A and R are true, R is the correct explanation for A
Both A and R are true, R is not the correct explanation for A
A is true, R is false
A is false, R is true
I would say it's "A is false, R is true"
Look at it this way, (R is talking): A is false, this is obviously true.
It wouldn't really work the other way.

The product of 6 and the sum of a number and 3 is 60
Answer:
8(x+3) is the answer
Step-by-step explanation:
The equation is 6(x + 3) = 60. Then the solution of the equation is 3.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The product of 6 and the sum of a number and 3 is 60.
Let the number be 'x'. Then the equation is written as,
6(x + 3) = 60
Simplify the equation, then the value of the variable 'x' will be calculated as,
6(x + 3) = 60
x + 3 = 60 / 6
x + 3 = 10
x = 10 - 3
x = 3
The equation is 6(x + 3) = 60. Then the solution of the equation is 3.
