Answer:

The subtraction of the given fractional expression is $\frac{1}{8}$

Therefore $\frac{1}{4}-\frac{1}{8}=\frac{1}{8}$

Step-by-step explanation:

Given fractional expression is $\frac{1}{4}-\frac{1}{8}$

To find the subtraction of the given fractional expression as below :

Subtracting the given fractions

$\frac{1}{4}-\frac{1}{8}$

$=\frac{\frac{1\times 8}{4}-1}{8}$

$=\frac{2-1}{8}$

$=\frac{1}{8}$

$\frac{1}{4}-\frac{1}{8}=\frac{1}{8}$

Therefore the subtraction of the given fractional expression is $\frac{1}{8}$

Therefore $\frac{1}{4}-\frac{1}{8}=\frac{1}{8}$

<h3>Answer: 10</h3>

Explanation:

"percent" means "per one hundred". Think "cent" as in "100 cents in a dollar". That's one way to remember.

So when we say something like 2%, we mean 2 out of 100 leading to the fraction 2/100 = 0.02

The same applies for 4.8% turning into 4.8/100 = 0.048

A quick shortcut without the use of a calculator has us move the decimal point 2 spots to the left to go from 4.8% to 0.048

-------------

After converting 4.8% to 0.048, we then multiply this by 200

200*(0.048) = 9.6

this value rounds to 10 which is the answer

3. Try It #3 Write the point-slope form of an equation of a line with a slope of -2 that passes through the point (-2,2). Then r

vova2212 [387]

Answer:

Point-slope form of equation given as $y-2=-2(x+2)$ .

Slope-intercept form of equation is given as $y=-2 x-2$ .

Step-by-step explanation:

In the question, it is given that the slope of a line is -2 and it passes from (-2,2).

It is asked to write the point-slope form of the equation and rewrite it as slope-intercept form.

To do so, first find the values which are given in the question and put it in the formula of point-slope form. Simplify the equation to rewrite as slope-intercept form.

Step 1 of 2

Passing point of the line is (-2,2).

Hence, $x_{1}=-2$ and

$y_{1}=2 \text {. }$

Also, the slope of the line is -2.

Hence, m=-2

Substitute the above values in point-slope form of equation given by $y-y_{1}=m\left(x-x_{1}\right)$

$\begin{aligned}&y-y_{1}=m\left(x-x_{1}\right) \\&y-2=-2(x-(-2) \\&y-2=-2(x+2)\end{aligned}$

Hence, point-slope form of equation given as y-2=-2(x+2).

Step 2 of 2

Solve y-2=-2(x+2) to write it as slope-intercept form given by y=mx+c.

$\begin{aligned}&y-2=-2(x+2) \\&y-2=-2 x-4 \\&y=-2 x-4+2 \\&y=-2 x-2\end{aligned}$

Hence, slope-intercept form of equation is given as y=-2x-2.

1 find the area in square cm of a square whose side is

lara [203]

For question 1:

Part i)

2.6 x 2.6 = 6.76 cm squared

No unit conversions needed

Part ii)

1.2 dm = 1.2 / 1000000 = 0.0000012 cm

0.0000012 x 0.0000012 = 0.00000000000144 cm squared

Question 2:

16.5dm = 16.5/ 1000 = 0.0165 m

0.0165 x 0.0165 = 0.00027225 m squared

I hope this has helped

Answer:

I think it may be 120 cm

Step-by-step explanation:

A F is 13 using pythagorean theorem on triangle CED and applying the hypotenuse length to A F.

ABC is similar to triangle CED and is dilated by a factor of 3 so the base is 36.

using pythagorean theorem on triangle ABC gets the hypotenuse length of 39 which can be applied to FE

add all the values together

39 + 13 + 15 + 36 +12 +5 = 120
