Answer:
<em>There are 12 boys and 18 girls</em>
Step-by-step explanation:
<u>Equations</u>
There are 30 students in a class. Let's call:
x = number of boys
Since the sum of boys and girls is 30:
30 - x = number of girls
The ratio of boys to girls is 2:3, thus:
Crossing denominators:
3x = 2(30 - x)
Operating the parentheses:
3x = 60 - 2x
Adding 2x:
5x = 60
Dividing by 5:
x = 60/5 = 12
x = 12
There are 12 boys and 30-12=18 girls
Answer To (b): 10 sandwiches in 20 minutes. But If Your Friend Arrived 10 Minutes Earlier, Then He Can Make 20 Sandwiches In The 20 Minutes That You Are There. If He Started When He Arrived And The Twenty Minutes Started Then, You Can Only Make 5.
Answer:
You have to use the equation 130+.40x and 70+.60x just replace x with any number, but the answer to each equation must be the same.

<h3><u>Given</u><u> </u><u>Information</u><u>:</u></h3>
- <u>Diameter of can</u>:- 3.6 cm
- <u>Height of</u><u> </u><u>can</u><u>:</u><u>-</u> 6.4 cm
<h3><u>To</u><u> </u><u>Find</u><u> </u><u>Out</u><u>:</u></h3>
- <u>Volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>Can</u><u>.</u>
<h3><u>Solution</u><u>:</u></h3>
Radius = (Diameter/2)
ㅤㅤㅤㅤ3.6 cm/2
ㅤㅤㅤㅤ1.8 cm
<u>So</u><u>,</u><u> </u><u>Radius</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>soup</u><u> </u><u>can</u><u> </u><u>is</u> 1.8 cm.
Volume øf cylinder = Volume øf can
Volume of cylinder = π r²h
(π = 22/7)
(r = radius = 1.8 cm)
(h = height = 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7×(1.8 cm)²× 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7× 3.24 cm² × 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7 × 20.736 cm³
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= (456.192/7) cm³
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 65.17 cm³
So, the Volume of the soup can is 65.17 cm³
