Answer:

Step-by-step explanation:

a) Price of 4 bowls of soup + 6 hamburgers = $30

4s + 6h = 30 ---------------------(I)

Price of 1 bowl of soup + 3 hamburgers = $ 12.75

s + 3h = 12.75 -------------------(II)

b) s = 12.75 - 3h

Substitute the value of s = 12.75 - 3h in equation (I)

4*(12.75 - 3h) + 6h = 30

4*12.75 - 4 *3h + 6h = 30

51.00 - 12h + 6h = 30

51 - 6h = 30 {Now subtract 51 from both sides}

51 - 6h - 51 = 30 - 51

-6h = -21 {Now, divide both sides by (-6)}

-6h/-6 = -21/-6

h = 3.50

Price of one hamburger = $3.50

Substitute the value of h in equation (II)

s + 3 *3.50 = 12.75

s + 10.50 = 12.75 {Subtract 10.50 from both sides}

s + 10.50 - 10.50 = 12.75 - 10.50

s = 2.25

Price of one soup = $ 2.25

c) Price of 1 soup and 1 hamburger = 2.25 + 3.50

Price of 1 soup and 1 hamburger = $ 5.75

Evan wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn, so he needs no fence

pentagon [3]

Answer: A. A=(1000-2w)*w B. 250 feet

C. 125 000 square feet

Step-by-step explanation:

The area of rectangular is A=l*w (1)

From another hand the length of the fence is 2*w+l=1000 (2)

L is not multiplied by 2, because the opposite side of the l is the barn,- we don't need in fence on that side.

Express l from (2):

l=1000-2w

Substitude l in (1) by 1000-2w

A=(1000-2w)*w (3) ( Part A. is done !)

Part B.

To find the width w (Wmax) that corresponds to max of area A we have to dind the roots of equation (1000-2w)w=0 ( we get it from (3))

w1=0 1000-2*w2=0

w2=500

Wmax= (w1+w2)/2=(0+500)/2=250 feet

The width that maximize area A is Wmax=250 feet

Part C. Using (3) and the value of Wmax=250 we can write the following:

A(Wmax)=250*(1000-2*250)=250*500=125 000 square feets

9(2*2+4➗2)= can you show how to get the answer. Which is 54.

Katen [24]

Here I'll Simplify it to show the work.
You need PEMDAS

9(2*2+4÷2)
9(4+4÷2)
9(8÷2)
9(4)
9(4) = 9 × 4 = 36

The Answer is 36.

Am i correct? calculus

Advocard [28]

Check the picture below.

now, the "x" is a constant, the rocket is going up, so "y" is changing and so is the angle, but "x" is always just 15 feet from the observer. That matters because the derivative of a constant is zero.

now, those are the values when the rocket is 30 feet up above.

$\bf tan(\theta )=\cfrac{y}{x}\implies tan(\theta )=\cfrac{y}{15}\implies tan(\theta )=\cfrac{1}{15}\cdot y
\\\\\\
\stackrel{chain~rule}{sec^2(\theta )\cfrac{d\theta }{dt}}=\cfrac{1}{15}\cdot \cfrac{dy}{dt}\implies \cfrac{1}{cos^2(\theta )}\cdot\cfrac{d\theta }{dt}=\cfrac{1}{15}\cdot \cfrac{dy}{dt}
\\\\\\
\boxed{\cfrac{d\theta }{dt}=\cfrac{cos^2(\theta )\frac{dy}{dt}}{15}}\\\\
-------------------------------\\\\
$

$\bf cos(\theta )=\cfrac{adjacent}{hypotenuse}\implies cos(\theta )=\cfrac{15}{15\sqrt{5}}\implies cos(\theta )=\cfrac{1}{\sqrt{5}}\\\\
-------------------------------\\\\
\cfrac{d\theta }{dt}=\cfrac{\left( \frac{1}{\sqrt{5}} \right)^2\cdot 11}{15}\implies \cfrac{d\theta }{dt}=\cfrac{\frac{1}{5}\cdot 11}{15}\implies \cfrac{d\theta }{dt}=\cfrac{\frac{11}{5}}{15}\implies \cfrac{d\theta }{dt}=\cfrac{11}{5}\cdot \cfrac{1}{15}
\\\\\\
\cfrac{d\theta }{dt}=\cfrac{11}{75}$
