What is 40% of 48.2 km

Answers

pretty sure its 19.28 kilometers

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

Use the fact that 13x17=221 to find the following and explain how you found each solution
13 × 1.7
130 x 17
13 x 1700
I do not understand what it wants me to do please help

Answers

Answer:

13 × 1.7

130 × 17

13 × 1700

13 × 17× 100

221 × 100

22100

So the answer is 22100

(13 x 17 = 221) given info

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

Step-by-step explanation:

Please hurry will give braliny

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.

Hope this helps!

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.

843

Because the difference was 1, just do -1x843 to get -843
