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
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.

Hello,
[tex]( {c}^{2} + {d}^{2} ) - 2( {c}^{2} - {d}^{2} )[/tex]
[tex] = (( - 2) {}^{2} + 2 {}^{2} ) - 2(( - 2) {}^{2} - 2 {}^{2} )[/tex]
[tex] = (4 + 4) - 2(4 - 4)[/tex]
[tex] = 8 - 2 \times 0[/tex]

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.
Hope this helps!

What is 40% of 48.2 km
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

or
Divide both sides by 2
or
Solve for x
or
or
Both values of x are negative.
This means that; the absolute value model cannot work, because a rectangle cannot have a negative dimension.
Hence, option (c) is correct.

Step-by-step explanation:
Here's way she is buying two candles which is $12 then to rush it it is an extra $8 adding them together you get only $20.
PLS HELP ME!!!! THIS IS DUE TOMORROW!!! v - 1/2 = -9/8
What is v?
Answer: v=-5/8
Step-by-step explanation:
v - 1/2 = -9/8
(v - 1/2 = -9/8)*8 ==> multiply the equation by 8 to get rid of fractions
8v - 8*1/2 = -9
8v-8/2=-9
8v-4=-9
8v=-5
v=-5/8
Answer: v=-5/8

Answer: -342.7074
Step-by-step explanation: first multiply 7(-2.655), which is -18.585. since only one of the numbers is negative, the product will also be negative. multiply -18.585 by 18.44. this is equivalent to -342.7074.
