T will always be q + 20, because she always talks for 20 minutes.
Q = 2, T = 22
Q = 4 T = 24
Q = 6. T= 26
Q = 8, T=28
Answer:
250 boys attended the conference.
Step-by-step explanation:
First, divide 750 by 3 (one-third of the conference is boys) and you will get 250 (number of boys). If you wanted to find the number of girls too, you would simply double 250 to get 500 girls.
(x+b/2a)^2-(b^2-4ac)/2a=0
Step 2:
Re-write the expression:
(x+b/2a)^2=(b^2-4ac)/4a^2
Step 3:
get the square root of both sides:
x+b/2a=sqrt[(b^2-4ac)/4a^2]
Step 4:
Simplifying we get:
x+b/2a=sqrt[b^2-4ac]/2a
Step 5
Make x the subject:
x=-b/2a+/-sqrt[b^2-4ac]/2a
Answer:
The surface of the triangular prism is 12 ft
Step-by-step explanation:
To find the surface area you have to multiply the base and the height and divide the product by 2
6 ft= base
4 ft= height
6 x 4 = 24
24 divided by 2 = 12
Answer:
35 cm ^2
Step-by-step explanation:
5x5 = 25
5-3 = 2
5x2 = 10
25+10 = 35cm^2
