The two integers are 7 and 5, 7*7=49, 5*5=25, 49-25=24
Answer:
620 elk
Step-by-step explanation:
Since 4 out of every 50 are infected, you first see how many groups of 50 there are in 7,750, so you divide it by 50, which equals 155. Then you multiply 155 by 4 because there are 4 likely infected in each group, and that gets you your answer of 620 elk.

Answer: The larger number be 61.
Step-by-step explanation:
Let the second number be 'x'.
Let the first number be 42+x
Average of two numbers = 40
According to question,
So, the larger number of the two numbers i.e the first number is
Hence, the larger number be 61.
Answer:
Below in bold.
Step-by-step explanation:
The surface area of the box
= x^2 + 4hx where x = a side of the square base and h is the height.
So x^2 + 4hx = 8
The volume of the box
V = x^2h
From the first equation we solve for h
4hx = 8 - x^2
h = (8 - x^2) / 4x
Now we substitute for h in the formula for the volume:
V = x^2 * (8 - x^2) / 4x
V = 8x^2 - x^4 / 4x
V = 2x - 0.25x^3
Finding the derivative:
V' = 2 - 0.75x^2 = 0 for max/mimn values
x^2 = 2/ 0.75 = 2.667
x = 1.633.
So the length and width of the base is 1.633 m and the height
= ( 8 - 2.667) / (4*1.633)
= 0.816 m
The maximum volume = 0.816 * 2.667 = 2.177 m^2.
The answers are correct to the nearest thousandth.
The answer is 394
but you need to figure with the distributive property to so your answer would look like this
(5 times 100)+ (5 times 90) + (5 times 8)
