3x - 2y; when x = 4 and y = 6

Question

topjm [15]

Answer:

1750

Step-by-step explanation:

The formula to find the volume of a rectangular prism is

$v=lwh$

We are given

$l=25\\w=7\\h=10$

We can then plug those values into the volume equation.

$v=(25)(7)(10)\\v=1750$

Ben and Cam are scuba diving. Ben is 15.815.815, point, 8 meters below the surface of the water. Cam is 4.24.24, point, 2 meters

alexira [117]

Answer:

Cam is at 6m below the surface of the water.

Step-by-step explanation:

Ignore all info except:

Ben is 8 meters below the surface of the water.

Cam is 2 meters above Ben

So now answer this;

What is Cam's position relative to the surface of the water?

This is too simple. Cam is 2 m above Ben which means two meter closer to the surface as Ben.

Ben was 8 m below the surface. By this Cam is 2 m closer to the surface, which is 8 - 2 = 6 m.

Cam is at 6m below the surface of the water.

Ravi sold 1/5 of his apples. He gave his friend 2/5 of the remainder. Ravi remained with 60. How many apples did ravi have at fi

zheka24 [161]

Answer:

The number of Apples did Ravi have at first is 125 .

Step-by-step explanation:

Let the number of Apples did Ravi have at first = x

The Apples which is sold by Ravi = $\frac{1}{5}$ of x

So, remainder now = x - $\frac{1}{5}$ of x = $\frac{4}{5}$ of x

The apples given to his friend = $\frac{2}{5}$ of $\frac{4}{5}$ x

I.e The apples given to his friend = $\frac{8}{25}$ of x

Now, The remaining Apples did Ravi have = 50

∴ According to question

$\frac{4}{5}$ of x - $\frac{8}{25}$ of x = 60

Or, $\frac{20-8}{25}$ of x = 60

Or, $\frac{12}{25}$ of x = 60

∴ x = $\frac{25\times 60}{12}$ = 125

Hence The number of Apples did Ravi have at first is 125 . Answer

Draw a line through the origin that has a slope of 4/3

Ket [755]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

In this problem the given line represent a proportional relationship, because passes through the origin

we have

$k=\frac{4}{3}$ ---> the constant of proportionality k is equal to the slope

substitute

The linear equation is

$y=\frac{4}{3}x$

To draw a line we need two points

we have (0,0)

To find the other point

assume x=3 and substitute in the equation to solve for y

$y=\frac{4}{3}(3)=4$

so

The other point is (3,4)

using a graphing tool

Plot the points (0,0) and (3,4)

To graph the line join the points

see the attached figure
