Answers
Answer:
b
Step-by-step explanation:
r = 1.5
Area/A = πr²
= π(1.5)²
= 7.07
A ÷ r = 7.07 ÷ 1.5
= 4.7
A ÷ r² = 7.07 ÷ 1.5²
= 3.1

The zoo is hosting a special evening event for visitors ages 12 and up. During the event, the price of popcorn is reduced from $3 per bag to $2 per bag. If 843 bags of popcorn were sold during the event, which integer expresses the total amount of money the zoo lost by reducing the price?
−$843
−$1
−$2
Answers
Answer: -$843
Step-by-step explanation:
843 x 3 = $2529
843 x 2 = $1686
2529 - 1686 = $843
The zoo makes $2529 on a regular night, but because there is a discount, they make $1686. The amount of money is the difference between the two totals. Therefore, the total amount of money the zoo lost by reducing the price is $843.
Because the difference was 1, just do -1x843 to get -843

Answers
Answer: D
Step-by-step explanation:
Follow the PEMDAS rule.
It’s not A, because when you solve 2^2 and sq rt of 4, the square exponent and the square root cancels out, so it’s simply 2 x 4. Then you follow by doing division and multiplication, 45/5 is 9 and 2 x 4 is 8, so 9+8=17.
It’s not B, because first solve the numbers in the parentheses. 2^2 is 4, 5+4 is 9. Then solve the square root of 4 which is 2, and you get 45/9x2, which is 10.
It’s not C because 2^2 is 4 and sq rt of 4 is 2, and 4-2 is 2. Then divide 45 by 5 to get 9, and 9+2 is 11.
The correct answer is D, because when you solve 2^2 which gives you 4 and add that to 5, you get 9. The sq rt of 4 is 2, so you get 45/9-2, which is 3.

So the answer is 22100
13 x 1.7 =22.1
130 x 17 =2210
13 x 1700 = 22100
Explanation: i believe your learning about how to move your decimal place. If you see the given information 17 is the number we are looking at. When the first equation comes up, there’s a decimal making 17 -> 1.7 . Then you move the decimal in the other direction making the 17. turn to 170. then 1700. Making your answer 22100

What is 40% of 48.2 km
Answers
Answer:
19.28 kilometers
Step-by-step explanation:
40 percent *48.2
= (40/100)*48.2
= (40*48.2)/100
= 1928/100 = 19.28
Now we have: 40 percent of 48.2 = 19.28
Question: What is 40 percent of 48.2?
We need to determine 40% of 48.2 now and the procedure explaining it as such
Step 1: In the given case Output Value is 48.2.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 48.2 = 100%.
Step 4: In the Same way, x = 40%.
Step 5: On dividing the pair of simple equations we got the equation as under
48.2 = 100% (1).
x = 40% (2).
(48.2%)/(x%) = 100/40
Step 6: Reciprocal of both the sides results in the following equation
x%/48.2% = 40/100
Step 7: Simplifying the above obtained equation further will tell what is 40% of 48.2
x = 19.28%
Therefore, 40% of 48.2 is 19.28
