Answer:

2/5

Step-by-step explanation:

5/5 = full job

3/5 = done

full job - done = remaining

5/5 job - 3/5 job

= 2/5 (remaining)

<h2>Answer:</h2><h2></h2><h3> $\frac{2}{5}$ is left to complete.</h3><h3></h3>

Step-by-step explanation:

To find out how much needs to be done, subtract the amount they got done by a whole fraction.

$\frac{5}{5}$ - $\frac{3}{5}$ = $\frac{2}{5}$

The line that passes through the point (2, −8) and has a slope of −1 is given by the equation y +

Nuetrik [128]

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line. Fill the point that the line passes through... ( , ) Example: (3,2) ...and the slope of the line. m= Example: m=3, or ... hope this helpps!!!!

Replace f(x)fx with yy.y=6x3−8y=6x3-8Interchange the variables.x=6y3−8x=6y3-8Solve for yy.
y=3√36(x+8)6y=36x+836Solve for yy and replace with f−1(x)f-1x.
f−1(x)=3√36(x+8)6

A fort had enough provisions for 100 men for 8 days. If 60 more men were joined then how many days the provisions will last for?

Grace [21]

Answer:

It would last for 3.2 days.

Step-by-step explanation:

100 men = 8 days

10 men = 0.8 days

60 men = 0.8 x 6 = 4.8 days

Now you subtract the days of 100 men and 60 men

8 - 4.8 = 3.2 days

Hope this helps!

Simplify: ((1/x+h)-(1/x))/h

Darya [45]

$\frac{( \frac{1}{x}+h)- \frac{1}{x} }{h}= \\ = \frac{ \frac{1}{x}+h- \frac{1}{x} }{h}= \\ =\frac{h}{h}= 1$
Thank you.

Please help and explain questions 20-22

zmey [24]

Hello!

The formula for circumference is $2\pi r$ and the formula for area of a circle is $\pi r^{2}$ . Armed with these formulas, we can begin to find the circumferences and areas of the circles.

20.
C = $2 \pi r$
C = $2 \pi (6.5)$
C = $13 \pi$
C = 13(3.14)
C = 40.8

A = $\pi r^{2}$
A = $\pi (6.5)^{2}$
A = $\pi (42.25)$
A = 132.7

The circumference of the circle is 40.8 in and the area of the circle is 132.7 in².

21.
[Since we are given the diameter for this problem, to find the circumference, we no longer need to multiply the radius by 2 as in $2 \pi r$ because the diameter is the radius × 2. For $\pi r^{2}$ we do need to divide the diameter by 2.]

C = $15.7 \pi$
C = 49.3

A = $\pi r^{2}$
A = $\pi (7.85)^{2}$
A = $61.62 \pi$
A = 193.5

The circumference of the circle is 49.3 in and the area of the circle is 193.5 in².

And that is all there is to it. I hope this helps you! (:
