Answer:
I think it is 588 cm squared
Step-by-step explanation:
42 x 28 = 1,176
1,176/2 = 588
Hello there! To solve for the total box office receipts, we can write and solve a proportion. Set it up like this:
270/x = 7.5/100
We do that, because we are looking for the total and 270 is the part of the whole. 270 makes up 7.5% of the box office receipts.
Now, we cross multiply. 270 * 100 is 27,000. 7.5 * x is 7.5x. Divideeach side by 7.5 to isolate the "x". 7.5x/7.5 cancels out the "x". 27,000/7.5 is 3,600. There. x = 3,600. The total box office receipts are $3,600.
You have 7 numbers, two numbers 4 , one 5, one 6 and three numbers 7.
From these 7 numbers you can create

phone numbers, but they are not all different.
If you have two numbers 4, then you have to divide obtained number by 2! (the number of all possible permutations of two numbers 4) and since you have three numbers 7 you should divide the obtained number by 3! (<span>the number of all possible <span>permutations of three numbers 7</span>). Then</span><span /><span>

Answer: You can create 420 different phone numbers.<span />
Foil the equation; j*k, j*-5, 7*k, 7*-5, once you foil add like terms.
jk - 5j +7k - 35 is the final answer
