Two numbers are in the ratio 3/4. If 4 is subtracted from each they are in the ratio of 5/7. Find the numbers!

frosja888 [35]

Answer:

The two numbers are 24 and 32

Step-by-step explanation:

We can use the variable x

3x : 4x, would be a ratio of 3/4

now subtract 4 from both

3x - 4 : 4x - 4 = 5/7

3x-4 / 4x-4 = 5/7

cross multiplication

7(3x - 4) = 5(4x - 4)

21x - 28 = 20x - 20

x = 8

Two numbers are;

3x, 4x

3(8), 4(8)

24, 32

24/32 = 3/4

20/28 = 5/7

Find the radius of a sphere given the volume. Volume= 121.5(pi) cubic ft. A 6.8 ft B 4.5 ft

IceJOKER [234]

Answer:

Radius of the sphere = $\sqrt[3]{91.13} \,feet$

Step-by-step explanation:

Volume of a sphere is :

$\dfrac{4}{3}\times \pi \times r^3$

For, Volume = $121.5\pi \,feet^3$

As, $\pi =\dfrac{22}{7}=3.14$

$121.5\times \pi =\dfrac{4}{3}\times \pi \times r^3 \\\\121.5=\dfrac{4}{3}\times r^3\\\\ 121.5\times \dfrac{3}{4} =r^3\\\\r^3=91.13\\\\r=\sqrt[3]{91.13} \,feet$

The radius of the sphere is : $\sqrt[3]{91.13} \,feet$

Determine the slope of a line that is parrallel to the equation 3x + 6y =18

Stolb23 [73]

<h2>SOLVING</h2>

$\Large\maltese\underline{\textsf{A. What is Asked}}$

Determine the slope of a line that is parallel to the equation $\bf{3x+6y=18}$ .

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

First we should divide the whole equation by 6,

$\bf{\dfrac{3}{6}x+\dfrac{6}{6}y=\dfrac{18}{6}}$ | simplify

$\bf{\dfrac{1}{2}x+y=3}$ | subtract 1/2 x

$\bf{y=-\dfrac{1}{2}x+3$

$\rule{300}{1.7}$

$\bf{Result:}$

$\bf{=Slope-\dfrac{1}{2}$

$\boxed{\bf{aesthetic\not101}}$
