Expression for ground area is 5 - 4x²
Step-by-step explanation:
- Step 1: Find the ground area without the two pits.
Ground area = 5 - 2x²
Pit 1 area = 2x²
Pit 2 area = 4x²
⇒ Expression for the ground area without the two pits
= (5 - 2x²) - (2x² + 4x²)
= (5 - 2x²) - (6x²) = 5 - 2x² - 6x² = 5 - 4x²
Answer:
25%
Step-by-step explanation:
Lets figure out how many students total in Lorenzo's grade:
7 students + 21 students = <u>28 total students</u>
<u />
We know that we can find the percentage by dividing our value by the total amount and multiplying it by , which is 1. (Multiplying by 1 does not change anything, which is why we choose to do this.)
Taking our known values,
<em>Therefore, </em><em>25%</em><em> of students voted for the athlete.</em>
Answer:
6x
Step-by-step explanation:
Perimeter is the sum of all the sides:
(x) + (2x + 2) + (3x - 2)
Add like-terms:
6x + 2 - 2 = 6x
Perimeter = 6x
Answer:
See the image below.
Step-by-step explanation:
The decimals 0.43 and 0.39 are equivalent to 43/100 and 39/100. These decimals lie between 0 and 1.
Draw a number line, mark off and label the multiples of 0.10(e.g 0.10, 0.20) in the interval 0-1.
Mark 0.43 between 0.4 and 0.5, a little closer to 0.4.
Mark 0.39 between 0.3 and 0.4, just behind 0.4.
Since 0.39 is smaller than 0.43( 0.39 lies on the left to 0.43), the inequality is:
0.39<0.43
Well since there are more than 10 people she should first get one box. She will then have 5 more people to feed so she will just have to buy another even though there will be leftovers.
