Answer:

? =6.97

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hyp

sin 35 = 4 / ?

Multiply each side by ?

? sin 35 = 4

Divide each side by sin 35

? = 4/sin 35

? =6.973787182

To the nearest hundredth

? =6.97

Answer:

Length = 400 m

Width = 200 m

Area = 80,000 m2

Step-by-step explanation:

Let's call the length L and the width W. Then, we have that the perimeter will be:

L + 2W = 800.

We want to maximize the area, that is:

A = L*W

so, from the first equation, we have:

L = 800 - 2W

Using this value in the area equation, we have:

A = (800 - 2W)*W = 800W - 2W^2

To find the maximum, we just need to find the vertix of the quadratic equation, and then apply the value to find the area:

W_vertix = -b/2a

Where a and b are coefficients of the quadratic equation (in our case, a = -2 and b = 800)

W_vertix = -800/(-4) = 200 m

A = (800 - 400)*200 = 80000 m2

L = 800 - 2W = 800 - 400 = 400 m

So the dimensions and area are:

Length = 400 m

Width = 200 m

Area = 80,000 m2

What percent of 25 is 17? Please show work, thank you.

Elina [12.6K]

First, you would need to create an equation for this problem. Let x represent the unknown percentage.
$\frac{17}{25}$ = $\frac{x}{100}$

Next, you would cross multiply.
25x = 1,700

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 25.
x = 68%

17 is 68% of 25.

I hope this helps!

From three chocolate bars we can make at most five chocolate rabbits and have some leftover. What is the greatest possible numbe

iogann1982 [59]

Answer:

The maximum number of chocolate rabbits that can be made from 16 chocolate bars = 27

Step-by-step explanation:

3 chocolate bars can make at most 5 chocolate rabbits.

Therefore, maximum number of chocolate rabbits that can be made from 3 chocolate bars = 5

$\text{So, maximum number of chocolate rabbits that}\\\text{can be made from 1 chocolate bar = }\frac{5}{3}$

Now, we are given 16 chocolate bars and need to find maximum number chocolate rabbits that can be made from the given number of chocolate bars.

$\text{So, maximum number of chocolate rabbits that}\\\text{can be made from 16 chocolate bars = }\frac{5}{3}\times 16\approx 26.67$

Hence, The maximum number of chocolate rabbits that can be made from 16 chocolate bars = 27
