Answer:
How to reflect a triangle around the line y=x
Step-by-step explanation:
The current area is 15 x 9 = 135 square feet.
He wants to increase both the length and width by X:
Set up an equation:
(15 +x) * (9 +x) = 135 * 2
Simplify :
x^2 + 24x + 135 = 270
Subtract 270 from both sides:
x^2 + 24x - 135 = 0
Use the quadratic formula to solve for x:
-24 +/- √(24^2 - 4(1*-135) / 2*1
x = 4.7 or -28.7
The answer has to be a positive value, so x = 4.7 feet.
The answer is math+math=math
Answer:
The chances of landing on blue are 1 in 4, or one fourth. The chances of landing on red are 1 in 4, or one fourth. This problem asked us to find some probabilities involving a spinner.
Given that 1/4 of the plants in the garden are peppers, and 1/3 of the 1/4 pepper plants are yellow peppers, we could get the fraction of the yellow peppers by multiplying 1/4 by 1/3. And we get the answer 1/12. Therefore, 1/12 is the fraction of yellow peppers.
