Answer:
w = 215 degrees
Step-by-step explanation:
A circle = 360 degrees total. So, 145 + w should equal 360.
145 + w = 360
145 + w -145 = 360 - 145
w = 215

Step-by-step explanation:
Monica forgot to multiply by 1/2
The area of the fabric is 243 in.2
Explanation:
The formula for the area of a triangle is:
1/2 • base • height
Monica’s error is that she only multuplied the base and height, without multiplying 1/2 also.
The area of the fabric is 243 in.2 because:
1/2 • 18 • 27 = 243
Or you could just divide the wrong area Monica solved (486 in2) by 2. You will also get 243 in.2
Have a nice day! And mark me brainliest please!

Answer:
Girls to boys = 1:2
Girls to students = 1:3
Boys to students = 2:3
Step-by-step explanation:
So, let's subtract the number of girls from the number of students in the class:
60 - 20 = 40
This means that for every 20 girls there are 40 boys in the ratio of girls to boys:
20:40
This can be simplified down by factoring, here we can divide by 20:
(20 ÷ 20) : (40 ÷ 20)
1:2
So the ratio of girls to boys is 1:2
The ratio of boys to students can be calculated via:
40:60
This can be simplified by dividing by 20 again:
(40 ÷ 20) : (60 ÷ 20)
2:3
So the ratio of boys to students is 2:3
The ratio of girls to students can be put in a ratio of:
20 : 60
This can be simplified down by dividing by 20:
(20 ÷ 20) : (60 ÷ 20)
1:3
So the ratio of girls to students is 1:3
Hope this helps!
