Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.

In fact, if the daughter weights d pound, the mother weights 4d pounds, and the total weight is d+4d = 5d.

We know that this total is 185 pounds, so we have

5d = 185 \iff d = \dfrac{185}{5} = 37

So, the daughter weights 37 pounds.

Two number cubes are rolled.
yaroslaw [1]

Answer:

1/4

Step-by-step explanation:

Assuming the number cube is a six-faced die, you have

1 <u>2</u> 3 <u>4</u> 5 <u>6</u>

three odd numbers, and three even numbers. Therefore, the chance of it landing on an odd number or even number is 3/6, which equals 1/2. <em>That means you have a 50% chance to get an odd number, or an even number.</em>

<em />

So, you have two die. Both have a 50/50 chance of getting an even or odd number. So what's the chance of one landing on an odd number, and the other landing on an even number?

  • You would have a 25% chance for an <u>even</u> and then an <u>even</u> number
  • You would have a 25% chance for an <u>odd</u> and then an <u>odd</u> number
  • You would have a 25% chance for an <u>even</u> and then an <u>odd</u> number
  • You would have a 25% chance for an <u>odd</u> and then an <u>even</u> number.

25% as a simplified fraction is 1/4. Therefore, 1/4 is your answer.

Please help asap.<br><br> please don’t take advantage of the points.
Verdich [7]

The answer is c = .6x + 5  

In order to find the equation, note that the price per pound is contingent upon the weight in x. Therefore, we can multiply the two together.

We also need to add the constant, which is 5.

Answer:

y =  -  \frac{11}{2} x + 30 \frac{1}{2}

or

y = 30 \frac{1}{2}  -  \frac{11}{2} x

if accepted:

2y =  - 11x + 61

or

2y = 61 - 11x
