Jared uses 24 tiles to cover the top of his desk. Of the 24 tiles, ⅜ are blue. How many of the tiles are blue?

1 answer:

7 0

You need to work out what an eight of 24 is:

\frac{1}{8} * \frac{24}{1}= \frac{24}{8} = \frac{3}{1}

Then you simply multiply 3 by 3 (as it is three eights not one) to get 9, so your answer is 9. $\frac{1}{8} * \frac{24}{1}
= \frac{24}{8} = \frac{3}{1}$

What is the fully simplified answer to sqrt(7/18) + sqrt(5/8) - sqrt(7/2)

NeX [460]

Answer:

$=\frac{-4\sqrt{7}+3\sqrt{5}}{6\sqrt{2}}$

Step-by-step explanation:

Given expression as:

$=\sqrt{\frac{7}{18}}+\sqrt{\frac{5}{8}}-\sqrt{\frac{7}{2} }$

We need to simplify the given expression.

Solution:

We have:

$=\sqrt{\frac{7}{18}}+\sqrt{\frac{5}{8}}-\sqrt{\frac{7}{2} }$

Rewrite the expression as:

$=\frac{\sqrt{7}}{3\sqrt{2}} - \frac{\sqrt{7}}{\sqrt{2}} +\frac{\sqrt{5}}{2\sqrt{2}}$

$\frac{\sqrt{7}}{\sqrt{2} }$ is a common factor to the first two terms.

Using distributive property we can factor out $\frac{\sqrt{7}}{\sqrt{2} }$ from the first two terms.

$=\frac{\sqrt{7}}{\sqrt{2}}(\frac{1}{3} -1) +\frac{\sqrt{5}}{2\sqrt{2}}$

$=\frac{\sqrt{7}}{\sqrt{2}}(\frac{1-3}{3}) +\frac{\sqrt{5}}{2\sqrt{2}}$

$=\frac{\sqrt{7}}{\sqrt{2}}(\frac{-2}{3}) +\frac{\sqrt{5}}{2\sqrt{2}}$

$=-\frac{2\sqrt{7}}{3\sqrt{2}} +\frac{\sqrt{5}}{2\sqrt{2}}$

$\sqrt{2}$ is common factor, so we can factor $\sqrt{2}$ from the above expression.

$=\frac{1}{\sqrt{2} }( -\frac{2\sqrt{7}}{3} +\frac{\sqrt{5}}{2})$

$=\frac{1}{\sqrt{2} }( \frac{-2\times 2\sqrt{7}+3\times \sqrt{5}}{6})$

$=\frac{1}{\sqrt{2} }( \frac{-4\sqrt{7}+3\sqrt{5}}{6})$

$=\frac{-4\sqrt{7}+3\sqrt{5}}{6\sqrt{2}}$

Therefore, we get simplified answer as.

$=\frac{-4\sqrt{7}+3\sqrt{5}}{6\sqrt{2}}$

The equation of the line with a slope of 6 and y-intercept of -1 is:

Andrew [12]

Answer:

$\bold{y=6x-1}$

Step-by-step explanation:

Hi there!

Since we are given the slope and the y-intercept of the line, we can very easily identify the equation of the line.

Slope-intercept:

y=mx+b

Plug in the values:

$\bold{y=6x-1}$

Thus, $\bold{y=6x-1}$ is the equation of the line.

Hope it helps! Enjoy your day!

Write a real-world situation that could be modeled by the equation 24/y=3. Then solve the problem. Anyone plz help me.

Bobby has 24 pizza slices
he divided them among his friends and each friend got 3 pieces
how many friends did he have

so
24 divided by number of friends=3
24/y=3
multiply both sides by y
24y/y=3y
24 times y/y=3y
24 times 1=3y
24=3y
divide both sides by 3
24/3=3y/3
8=3/3y
8=1y

y=8
8 friends

The equation for the cross-section of a parabolic satellite TV dish is stated below, measured in inches. How far is the focus fr

leonid [27]

The coordinates of the focus are (h,k+1/4a)(h,k+1/4a)

y=1/38*x^2
here h=0,k=0 ,a=1/38

so if we put values to find focus
focus(0,0+1/4*1/38)=(0,9.5)
