Let n = minutes since 12:00 pm when Malory catches up to Dori.
Dori travels
(50 steps/min)*(n minutes) = 50n steps
Malory begins walking at 12:20 pm, so she walks for (n - 20) minutes. She travels
(90 steps/min)*(n - 20 min) = 90n - 1800 steps
Equate the steps traveled by Dori and Malory.
90n - 1800 = 50n
40n = 1800
n = 45 min
The time corresponding to n = 45 min is 12:45 pm
Answer: 12:45 pm
We are asked in the problem to determine the number of quarters that are needed to complete 4975 units given the equation y = x6 − 25x4 + 199x2 where y is the number of manufactured units and x is the number of quarters needed.
substituting y = 4975, we find x. <span>x is readily found using calculator.</span>
Oakdale is the answer I think
Answer:
Jillian is incorrect because square roots of perfect squares are rational.
Step-by-step explanation:
√25 = √(5²) = 5 - rational
25 is perfect square.
Rotated

Explanation:</h2>
Remember you have to write complete questions in order to find good and exact answer. So in this case I'll provide a general explanation and say that the blank can be filled with the word rotated. First of all, when dilating objects we reduce or enlarge the size of them. It's important to know the scale factor because this tells use whether the object will be larger or smaller, so if we call
the scale factor, then:
- If k > 0 then the object will be larger than the original.
- If k < 0 then the object will be smaller than the original.
Moreover, the center of dilation is the point where all the lines that meet corresponding points of the original and dilated figure.
On the other hand, to rotate a shape we turn it about a fixed point that we call the center of rotation. So, in this case we'll have that ΔMNO is similar to ΔYHQ.
