Divide £50 in the ratio of 1:4

1 answer:

6 0

Answer=10:40

Explanation:

Don’t know how to type the symbol in font of the 50 so I will substitute
£50=$50

So 1:4
Add it up
1+4=5

So 5 total units
$50=5
Divided by 5
$10=1 units

So 1:4=10:10 times 4=10:40

<u>Answer:</u>

3/5

<u>Step-by-step explanation:</u>

We are to find the similarity ratio of a cube with volume $729 m^3$ to a cube with volume $3375 m^3$ .

We know the formula for the ratio of two cubes:

$\frac{V_1}{V_2} =k^3$

where $k$ is the similarity ratio of the two cubes.

Substituting the given values in the formula to find $k$ :

$k^3 = \frac {729} {3375}$

$k^3 = \frac {27} {125}$

$k^3 = (\frac {27} {125})^3$

$k=\frac{3}{5}$

Therefore, the similarity ratio of the two cubes is 3/5.

Each grade level at Hooperville Schools has 298 students.

madreJ [45]

Answer:

(a) 3,874 students.

(b) 46,488 students.

Step-by-step explanation:

We have been given the each grade level at Hooperville Schools has 298 students.

(a) To find the number of students that attend Hooperville Schools, we will multiply the number of grades by 298.

$\text{Students that attend Hooperville Schools}=13\times 298$

$\text{Students that attend Hooperville Schools}=3,874$

Therefore, 3,874 students attend Hooperville Schools.

(b) We have been given that nearby district, Willington, is much larger. They have 12 times as many students.

To find the number of students that attend schools in Willington, we will multiply number of students at Hooperville schools by 12.

$\text{Students that attend Willington Schools}=12\times 3,874$

$\text{Students that attend Willington Schools}=46,488$

Therefore, 46,488 students attend schools in Willington.

Give the equation of a line that goes through the point ( − 24 , 2 ) and is perpendicular to the line 8 x + 3 y = − 6 . Give you

Studentka2010 [4]

Answer:

$y=\frac{3}{8}x+11$

Step-by-step explanation:

To find a line that is perpendicular to 8x + 3y = -6 and goes through (-24, 2), lets first find what the line's slope would be.

We can find this by finding the slope of 8x + 3y = -6 and taking the negative reciprocal of it.

We can find the slope of that line by putting it in slope-intercept form:

8x + 3y = -6

Subtract 8x from both sides.

3y = -6 - 8x

Divide both sides by 3.

$y=-\frac{6}{3}-\frac{8}{3}x$

$y=-\frac{8}{3}x-2$

So the slope of that line would be -8/3.

The negative reciprocal of -8/3 would be 3/8.

Now we know that the new line would have to pass through the point (-24, 2). We can use this point and write the equation in point-slope form:

$y-2=\frac{3}{8}(x+24)$

Now lets change this into slope-intercept form. Add 2 to both sides.

$y=\frac{3}{8}(x+24) +2$

Distribute the 3/8.

$y=\frac{3}{8}x+9+2$

Simplify.

$y=\frac{3}{8}x+11$

And now we have our equation in slope-intercept form.

I hope you find this helpful.
