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:
105°
Step-by-step explanation:
We have,
- The inferior angles of the triangle are in the ratio 1:3:8.
We've to calculate the difference in size between the largest and smallest angles.
Let's find the sizes or the values of the angles first.
Let us assume the interior angles of triangle as 1x , 3x and 8x as they are in the ratio 1:3:8.
★ According to the angle sum property of the triangle, the sum of the interior angles of the triangle is 180°. So,
→ 1x + 3x + 8x = 180°
→ 12x = 180°
→ x = 180° ÷ 12
→ <u>x = 15°</u>
Now, the sizes of the angles are,
- First angle = 1x = 1(15) = 15°
- Second angle = 3x = 3(15) = 45°
- Third angle = 8x = 8(15) = 120°
First angle is the smallest angle and the third one is the largest.
→ Difference = Third angle – First angle
→ Difference = 120° – 15°
→ <u>Difference = 105°</u>
Therefore, the difference in size between the largest and smallest angle is 105°.
