Answer:

It will take 5 hours to fill the order.

Step-by-step explanation:

Set up an equation, 40x=200, x being how many hours it will take.

Divide 40 by 200 to get x alone, x=200/40

x=5 hours.

hello

John can bake 40 cookies in 1 hour and a school ordered 200 cookies, you need to find how many hours it is going to take to make those 200 cookies.

1 hour is 60 minutes

so              40 cookies in     60 minutes    (we will convert it to hours later )

                 200 cookies in    ????  minutes

step 1 : use fractions -> (40 COOKIES )/ (60 MINUTES ) = (200 COOKIES)/(x MINUTES )     (x being an unknown variable)

step 2: cross multiply until x is left alone on one side (((200 cookies ) * (60 minutes))/(40 cookies)) = x MINUTES

step 3: solve for unknown and cross out like terms  : 200*60=1200, 1200/40=300

step 4 convert minutes to hours

          since 60 minutes are 1 hour

                    300 minutes are ? hours

step 4 cross multiply again  (300*1)/60 = 5 hours

Komok [63]
We know that

step 1
the area to install tiles is equal to A
A=area rectangle-area of a circle

area of a rectangle=(13+x)*x-----> (13x+x²) ft²

area of a circle=pi*r²-----> pi*6²------> 36*pi ft²
A=(x²+13x)-36*pi  ft²

step 2
find the cost of installing tiles CT
CT=$1*[(x²+13x)-36*pi]-----> CT=$x²+$13x-$36*pi

step 3
find the cost <span>the of installing the pond CP
CP=$0.62*36*pi------> CP$22.32*pi

step 4
find the inequality
we know that
CT+CP </span>\leq<span> $536
[</span>$x²+$13x-$36*pi]+[$22.32*pi]  \leq $536

[$x²+$13x-$13.68*pi]  \leq $536

the answer is the option D

the average of two numbers is 34. The second number is three times the first number. What are the two numbers?
zvonat [6]
Hey!To solve this problem, we need to set up two equations and use the system of equations to solve.

Let x be the first number.
Let y be the second number.

(x + y) ÷ 2 = 34
x = 3y

Now, we can use substitution to solve.

(3y + y) ÷ 2 = 34
4y ÷ 2 = 34
2y = 34
y = 17

Now, you plug the value of y in the equation to solve for x.

x = 3*17
x = 51
hope this helps!!

Please help me find out what k is.
Ghella [55]

Answer: a) k=8

b) The area of the addition =30\text{ square feet}

The area of the entire patio after addition =80\ \text{square feet}

Step-by-step explanation:

Given: The area of the patio before addition = 50 square feet

The area of the addition portion is given by k^2-3k-10

We can see that dimension of the total portion is k\times(k+2)

therefore, the area of the patio with the addition portion = k\times(k+2)=k^2+2k

According to the question we have,

k^2-3k-10+50=k^2+2k\\\Rightarrow-3k+40=2k\\\Rightarrow\ 5k=40\\\Rightarrow\ k=8

Therefore,  The area of the addition =8^2-3(8)-10=64-24-10=30\text{ square feet}

The area of the entire patio after addition =  30+50=80\ \text{square feet}
