Answer:
137.5 cm ^2
Step-by-step explanation:
9*11 = 99
(7*11)/2=38.5
99+38.5=137.5
So. hmmmm notice the first picture, that's a rectangular prism
is really just 6 rectangles stacked up to each other at the edges
now, notice the second picture, is a prism/shelf with a length of 48, width of 12 and height of 1
so, your shelf is really just 6 rectangles stacked up to each other at the edges
you have 2 rectangles of 48x1 on the sides
2 rectangles of 12x1 for the front and back
and 2 rectangles of 12x48, for the top and bottom
get the area of each of those rectangles, add them up, and that's the surface area of the shelf
Answer: 1.5 kilometers.
Step-by-step explanation:
You need to make the conversion from 500 meters to kilometers.
It is important to remember that:
Then, 500 m to km is:
Now you know that he ran 0.5 kilometers in each of his last three track meets.
To calculate the total amount of kilometers ran in those three meets, you need to multiply 0.5 kilometers by 3. Then:
Answer:
Company X - 190 students
Company Y - 114 students
No phones - 76 students
Step-by-step explanation:
1) Find a multiplier to get the ratio from sample to population; to compare the sample to the population
380/120 = 3.16666667 or 3 & 1/6
380 comes from the total population of students and 120 comes from the randomly selected.
2) Use our multiplier to compare the results to the population
<u>People with Company X</u>
<u>People with Company Y </u>
<u>People with no cell phone</u>
- 24 * 3.166667 = 76.0000000001 = 76 (rounded)
<u>Double check</u>
190 + 114 + 76 = 380
Answer:
Step-by-step explanation:
The initial price of the swimsuit that Karla purchased at Amazon was 75.5
she use the coupon code to receive a 25% discount. This means that the value if the discount would be
25/100 × 75.5 = 0.25× 75.5 = 18.86
Therefore, the discounted price of the swimsuit is 75.5 - 18.875 = 56.625
The website applied a 10% service fee for the discount price. This means that the value of the service fee would be
10/100 × 56.625 = 0.1 × 56.625 = 5.6625.
The amount that Karla pays for the swimsuit would be
56.625 + 5.6625 = 62.2875
The difference between the original price and the price that Karla paid would be 75.5 - 62.2875 = 13.2125
The percentage by which the amount that Karla paid was lesser than the original price would be
13.2125/ 75.5 × 100 = 17.5%
