Answer: Length is 12in and width is 16in

Let's use the ratio method!

3+3+4+4 is 14

Let's think the length as," L " and the width as," W "

L / 56 = 3/14

L = 3/14 * 56

L = 12

And for width:

W / 56 = 4/14

W =4/14 * 56

W = 16

There you go! We did it!

When a jar of fruit is 2/3 of the way full it can hold 2 1/4 cups of fruit what fraction of the jar is full when it only contain

Natali [406]

Answer:

8/27

Step-by-step explanation:

<h2><u>Fractions</u></h2>

a jar of fruit is 2/3 of the way full it can hold 2 1/4 cups of fruit

what fraction of the jar is full when it only contains one cup of fruit?

by using these statements , we can solve this through <u>cross multiplication</u>:

fraction that the jar is full : number of cups of fruit

$\frac{2}{3}$ : $2 \frac{1}{4}$

x : 1

$\frac{2}{3} = 2 \frac{1}{4} x$

convert $2 \frac{1}{4}$ from a mixed fraction to an improper fraction

hence 2 1/4 = 9/4

solve

$\frac{2}{3} = \frac{9}{4} x$ .

x = $\frac{2}{3} / \frac{9}{4}$

<h3><u>when the cup contains one cup of fruit its fraction 8/27 full </u></h3>

Lapatulllka [165]

Answer:

Step-by-step explanation:

Given that there is a function of x,

$f(x) = 2sin x + 2cos x,0\leq x\leq 2\pi$

Let us find first and second derivative for f(x)

$f'(x) = 2cosx -2sinx\\f"(x) = -2sinx-2cosx$

When f'(x) =0 we have tanx = 1 and hence

a) f'(x) >0 for I and III quadrant

Hence increasing in $(0, \pi/2) U(\pi,3\pi/2)\\$

and decreasing in $(\pi/2, \pi)U(3\pi/2,2\pi)$

$x=\frac{\pi}{4}, \frac{3\pi}{4}$

$f"(\pi/4)$

Hence f has a maxima at x = pi/4 and minima at x = 3pi/4

b) Maximum value = $2sin \pi/4+2cos \pi/4 =2\sqrt{2}$

Minimum value = $2sin 3\pi/4+2cos 3\pi/4 =-2\sqrt{2}$

f"(x) =0 gives tanx =-1

$x= 3\pi/4, 7\pi/4$

are points of inflection.

concave up in (3pi/4,7pi/4)

and concave down in (0,3pi/4)U(7pi/4,2pi)
