Answer:
24 cm^2
Step-by-step explanation:
Find Side Length:
20cm/4 = 5cm
Use x:
First Diagonal - 4x; Second Diagonal = 3x
Pythagorean Theorem:
a^2 + b^2 = c^2
Use Pythagorean Theorem:
a = 1/2 of First Diagonal
b = 1/2 of Second Diagonal
c = Side Length
2x^2 + 1.5x^2 = 5^2
4x^2 + 2.25x^2 = 25
6.25x^2 = 25
x^2 = 4
x = 2
Formula for Area of Rhombus:
1/2 * First Diagonal * Second Diagonal
Use Formula for Area of Rhombus:
1/2 * 4(2) * 3(2)
= 1/2 * 8 * 6
= 4 * 6
= 24 cm^2

Answer:
C - a stack of 15.6 watermelons
Step-by-step explanation:
Lets first go through each option:
<u>"A shopping receipt that totals $4.90"</u>:
This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.
<u>"A soccer game where the average score is 4.7"</u>:
This is also an appropriate result since it is the <em>average</em> score of a soccer game, so finding a decimal is appropriate.
<u>"A stack of 15.6 watermelons"</u>:
This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.
<u>"A classroom with 24 students"</u>:
This is an appropriate result since the number of students is a whole number not a decimal.
Hope this helps :)
You are correct. the answer is 4/7 and there are 12 girls and 16 boys.
Hope this helps.
The answer is B because I did the math
