Answer:
30 times
Step-by-step explanation:
Jeanna : Haylee = 2 : 5
The number of times Haylee babysits in one month is unknown, so it is represented as x.
Write a new ratio to represent the scenario
2 : 5 = 12 : x
Ratios can be written as fractions
Rewrite
2/5 = 12/x
Cross multiply (numerator * denominator / numerator * denominator)
2x = 60
x = 30
Haylee babysat 30 times that month
Hope this helps :)
The number 57 is a rational number. Rational numbers can be written as a fraction. 57/1 is an example. Irrational numbers cannot be written as a fraction. Example of an irrational number would be square root of 5.
800$ because yearly he would deposit 8000$ and 10% of that would be 800$ :)
Answer:
Step-by-step explanation:
Total number of stamps = 26 + 45 = 71
You can't reduce whatever you put into the numerator because 71 is prime (nothing but itself and 1 divide into it).
Number of stamps of famous people = 45
Ratio = famous people / total
Ratio = 45 / 71
Answer:
A horizontal line; a melting ice cube.
Step-by-step explanation:
A constant interval appears as a horizontal line. The graph in the interval has a slope m = 0.
Here's an example of a constant interval.
You take an ice cube from the freezer and place it in a container on the counter.
The temperature of the ice cube is -5 °C. The ice cube will warm to 0 °C, and then it will start to melt. While it is melting, the temperature is constant at 0 °C.
When the ice has completely melted, the water will start warming to room temperature.
A plot of <em>temperature vs. time</em> would look something like the graph below.
The interval AB, where the ice is melting, is a constant interval.
