Answer:
If there are 12 white horses in 5 a herd of 52 horses, there will be 40 black horses if there aren't any other color horses.
The ratio will be 40 : 12
To simplify, it will be 10 : 3
Factor out the common term x
x(x^2 + 18) = 0
Solve for x; How?
Ask yourself: When will x(x^2 + 18) eqal zero?
When x = 0 or x^2 + 18 = 0
Solve each of the 2 equations above
Thus, x = 0, ±3√2i
Answer:
∠M = 78º
∠N = 68º
∠P = 34º
Step-by-step explanation:
we know that the inside of a triangle is equal to 180º. we also know that angle p and angle q equal 180º when added together because that's the angle of a straight line. first we need to find angle p.
180 - 146 = 34º
now we can set it up so that all the angles equal 180º when added together.
(5y + 3) + (4y + 8) + 34 = 180
5y + 4y = 9y
9y + 3 + 8 + 34 = 180
3 + 8 + 34 = 45
9y + 45 = 180
-45 -45
-------------------
9y = 135
÷9 ÷9
y = 15
now we can plug 15 in for y
(5 x 15 + 3) = 78º
(4 x 15 + 8) = 68º
to double check, add all three angles and make sure they equal 180º
78 + 68 + 34 = 180
Hello!
First you have to add the number of fish
52 + 61 + 87 = 200
Then you find the percentage of grass carps
61/200 = 0.305
Then you multiply what you just got with the estimated sample
800 * 0.305 = 244
The answer is 244
Hope this helps!
Answer: 34
Step-by-step explanation:
Divide the number of ornaments by the number of sections in the plastic containers.
204/6= 34
