18kg in the ratio 2:7​

Mathematics
1 answer:
fredd [130]3 years ago
8 0

Answer:

Step-by-step explanation:

Let the ratios be 2x and 7x respectively.  

Now,

2x + 7x = 18

= 9x = 18

= x = 18/9

= x = 2

Hence, 2x = 2*2 = 4

And, 7x = 7*2 = 14

svp [43]
Your answer is: $3.15 each.

Here are the steps:

First, I added $2.82 and $1.43. Then, I subtracted the sum ($4.25) from $20. Lastly, I divided the difference($15.75) by five because there were five pineapples. Which gave me the answer: $3.15.

Answer:

The answer is x=294 (B)

Step-by-step explanation:

Remember, all interior angles of a hexagon add to 720.

So add all the  given numbers first.

92+100+94+140+x= 720

426+x=720

-426 from both sides

x= 294

I know this is a week later since you posted the question, sorry.

Help I will give brainiest​
sdas [7]

Answer:

1.  V = 94 meters cubed

2. V = 8 feet cubed

3.  V = 57 inches cubed

Step-by-step explanation:

The volume of a cone is 1/3 the volume of a cylinder. So all you need to do is plug the numbers into the formula for the volume of a cylinder and then you have the answer.

The formula for a cylinder is V= (3.14 or pi) * radius squared * height

The formula for a cone is V= (3.14 or pi) * radius squared * height * 1/3

So here you go.....

1. V= 3.14 x 9 x 10 x 1/3                V = 94 meters cubed

2. V= 3.14 x 4 x 2 x 1/3                   V = 8 feet cubed

3. V = 3.14 x 9 x 6 x 1/3                  V = 57 inches cubed

Please give me brainiest!

\begin{gathered} a)slope\colon7 \\ b)y-intercept\colon-6 \end{gathered}

1) As we can see this is a Linear Equation written in the Slope-intercept form:

y=mx+b

Note that "m" stands for the slope of the line, i.e. the measure of how steep a line is.

In the given equation, we can state that the slope is always accompanying the "x" therefore, the slope is m= 7

2) In addition to this, the y-intercept also called the Linear Coefficient is given by the letter"b" and represents the y-coordinate that the graph intercepts. Thus the y-intercept is -6

So we can state the following as the answers:

\begin{gathered} a)slope\colon7 \\ b)y-intercept\colon-6 \end{gathered}

And that is the answer
