12in=1ft
39/12=3.25ft
1m=3.25ft
times 4 both sides
4m=13ft
12ft
C
Answer:
Blue: 2/3
Purple: 1/3
Step-by-step explanation:
You have a total of 3 possible sections.
For blue, we have 2 out of 3 sections. The probability is 2/3.
For purple, we have 1 out of 3 sections. The probability is 1/3.
Answer:
- as written, -57
- as perhaps intended, C. -11
Step-by-step explanation:
The expression shown evaluates as ...
7 + 32(-5 +1)/2 = 7 +32(-4)/2 = 7 -128/2 = 7 -64 = -57
_____
If we assume your "32" is supposed to be 3², or 3^2, then the expression evaluates differently:
7 +3²(-5 +1)/2 = 7 + 9(-4)/2 = 7 -36/2 = 7 -18 = -11 . . . . matches choice C
_____
When in doubt, you can have the Google calculator evaluate your expression. However, you do have to write it properly and with all the required parentheses.
Answer:
Step-by-step explanation:
Total profit function is equal to Total revenue function minus Total Cost function.
To get both Revenue function and Cost function, integrate the Marginal functions as follows:
R(t) = 108.7312t^2
Where 80et = 217.4624t
(e =2.71828)
C(t) = 80t - 0.4t^2
P(t) = R(t) - C(t) = 109.1312t^2 - 80t
When t=0, P=0
When t=1, P=29.1312
When t=2, P=276.5248
When t=3, P=742.1808
And so on ...
Summing the daily profits, total profit for the 10 days is 37,615.512 dollars which equals 3,761551.2 cents
(B)
Average daily profit for the first 10 days (in dollars) is 37,615.512÷10 = 3,761.5512 dollars
= 376,155.12 cents
Answer:
The value of x is 16
Step-by-step explanation:
In the right triangle of the length of the hypotenuse c and the lengths of two legs a and b
- a² + b² = c² ⇒ Pythagoras Theorem
In the given figure
∵ The right triangle has two legs of lengths 8√2, 8√2
∴ a = 8√2 and b = 8√2
∵ It has a hypotenuse of length x
∴ c = x
→ Substitute them in the rule above
∵ (8√2)² + (8√2)² = x²
∵ (8√2)² = (8)²(√2)² = (64)(2) = 128
∴ 128 + 128 = x²
∴ 256 = x²
→ Take a square root for both sides
∵ √256 = √(x)²
→ The root will cancel power 2 of x
∴ 16 = x
∴ The value of x is 16
