To find out the answer,we can test it out one by one:
The original expression: 6×(2+8)=60
A. 6x(8+2)= 6x10 = 60✅
B. (6×2)+8 = 24+8 = 34
C. (8+2)x6 = 10×6 = 60✅
D. 6x2÷6×8 =12÷6×8 = 2×8 = 16
As A. and C. equals to the original expression, the answer is A. and C.
Work shown above! Answer should be D!
Answer:
12,435 bats
Step-by-step explanation:
We need to figure out how many bats were produced.
First let's write the equation. Cost is $28 for each bat, and we start with fixed expenses of $58,780
y=28x + 58780
We are given y, total expenses at 406,960
so 406,960 = 28x + 58780
subtract 58780 from both sides
406,960 - 58,780 = 28x
348,180 = 28x
divide both sides by 28
12,435 = x
This means they produced 12,435 bats.

Answer:
Last option 527.7 ft
Step-by-step explanation:
From the diagram attached we can see the angle of depression is 80.2 which is equal to ∠ACB (alternate angles)
Height of the deck AB = 520 ft. and we have to calculate the distance H between the tourist and her friend.
Sin ∠ACB = 
Now we apply sin rule sin 80.2 = 
So the tourist and her friend are 527.7 ft apart.
