I think the answer to this is: 25q + 10d + 5n + 60 = 87
The story says that you have 1 dollar and 87 cents; 60 cents
of which is pennies. So, if you’re using an equation involving quarters, dimes
and nickels, the total equation should equal to 87 cents (since that dollar
bill could not be broken down to cents).
This problem mentions 'CHOICE,' which means you need to share the several possible answers that came with this problem.
There is an upfront charge of $12 per car. Next, each person in the car is charged $1. Supposing that x people are in the car, then the total cost, C(x), is
C(x) = $12 + ($1)x. This is a linear function whose domain could be, for example, [0,6], assuming that 6 people could fit into the car.
Hey There!
The formula of the general form equation is
0 = Ax + By + C
As we look at the answer choices we see that the last choice best represents the correct answer.
x + y + 2 = 0
Best matches the formula given and therefore that would be the correct answer.
Thus, the answer would be x + y + 2 = 0

Answer:
a) 0.75
b) 0.0625
c) 0.1875
d) 0.375
Step-by-step explanation:
Let's start by first finding the probability a teacher orders 6 boxes. Since it is a four sided dice, the probability of getting a 1 is going to be 0.25.
Similarly, for any other number on the dice, the teacher orders 2 boxes. We can think of this as NOT rolling a 1. Using our previous answer, this comes out to be: 1 - 0.25 = 0.75
It should be remembered in the following answers that teachers ordering 6 or 2 boxes are not influenced by the results of other teachers. These are statistically independent events.
a) As given above, this probability is 0.75
b) The probability that both teachers order 6 boxes will be their individual probabilities multiplied. This comes out to be: 0.25 x 0.25 = 0.0625
c) Like in part (b), this is both of their probabilities multiplied:
0.25 x 0.75 = 0.1875
d) This is nearly the same as part (c), but with a little twist. The order matters. There are two scenarios:
- First teacher gets 6 boxes, and the second gets 2.
- First teacher gets 2 boxes, and the second gets 2.
Both of these events have a probability of 0.1875, as shown in (c). To get the total probability of this event happening, we must add these together:
0.1875 + 0.1875 = 0.375
Answer:
Base = 3√5
Step-by-step explanation:
Given:
Hypotenuse = 9
Perpendicular = 6
Find:
Base(x)
Computation:
Using Pythagorean theorem
Base = √Hypotenuse² - Perpendicular²
Base = √9² - 6²
Base = √81 - 36
Base = √45
Base = 3√5
