Answer:
80 miles
Step-by-step explanation:
Speed is 30 miles/hour
Time is 2 hours 40 minutes or 2 2/3 hours or 8/3 hours
Distance is speed x times
so distance is 30 x 8/3 = 80 miles
Equation 1. The rate of change is 3. In equation 2, you must divide each side by 2, giving you a rate of 5/2, which is 2.5. And 2.5<3
The probability of losing per flip is 1/2. Multiply 1/2 by itself 6 times since the condition is asking for the probability for the person to lose 6 times in a row. 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/64. The answer is 1/64.
Your answer is $1.26
You can solve this problem with or without a calculator, and I don't know if you're allowed one or not so I'll show you both ways
Calculator:
The easiest way to find percentages of values on the calculator is to use the decimal multipliers, which are just the decimal value of the percentage. For example, 50% would be 0.5, 75% would be 0.75 etc. The decimal value of 15% is 0.15, so you would do 8.40 × 0.15 = 1.26
Non-Calculator:
This is a bit longer, but gives you the same answer. To solve without a calculator, you first divide 8.40 by 10 to find 10%, which is 0.84. Now you can divide that by 2 to find 5%, which would be 0.42, and then you add the two values (because 10% + 5% = 15%) to get 1.26
I hope this helps!
Answer:
Y=2x+2
Step-by-step explanation:
2x is the positive gradient
and +2 is where it passes through the y axis
