Answer: 2/5 = 0.4 = 40%
Step-by-step explanation:
Each sector has an equal area, so each sector has an equal chance of being landed on. There are two shaded sectors and 5 total, so there is a 2 out of 5 chance that the spinner will land on a shaded one.
Answer:
since its an isosceles trigon and OR=OP then angle P is going to be equal with angle R so P=R=50°
Answer:
-b = 14
-n = 28
Step-by-step explanation:
For b
50/100=b/28 cross-multiply
1400= 100b divide both sides by hundred
-b = 14
For n
25/100= 7/n cross multiply
25n = 700 divide both sides by 25
-n = 28
If the required rate is gallons per minute, then its obvious from the question, that the rate of filling the pool is 10 gallons per minute, and its obviously a constant number.
But for the rate to be in gallons per hour, then
1 minute corresponds to 10 gallons
so
1 hour corresponds to 10x60 = 600 gallons
hence
rate (gallons per hour) = 120,000/600 = 200 gallons per hour.
which is again a constant number.
Answer:
15ab
Step-by-step explanation:
When you multiply out the square (p+q)^2, you get the trinomial ...
(p +q)^2 = p^2 + 2pq + q^2
Your binomial is (3a+2.5b), so you have ...
p = 3a
q = 2.5b
and the trinomial you get when you multiply it out is ...
(3a)^2 + 2(3a)(2.5b) + (2.5b)^2
= 9a^2 + 15ab + 6.25b^2
The first and last of these terms are shown on the right side of the given expression, so to finish out the identity, you need to replace * with 15ab.
