The two consecutive odd numbers that have a product of 15 are 3 and 5
There are 100 random 2 digits numbers [00 , 99]
There are 34 divisible by 3 {00, 03, 06, 09, … 93, 96, 99}
There are 20 divisible by 5 {00, 05, 10, … 90, 95}
However we must avoid counting numbers twice so we need to subtract those divisible by 15.
There are 7 divisible by 15 {00, 15, 30, 45, 60, 75, 90}
This means there are 34 + 20 - 7 = 47 2-digit numbers that are divisible by 3 or 5.
If you pick a random 2-digit number then P(divisible by 3 or 5) = 47/100 = 0.47
Answer:
4x4=16 and 7x6=42. So add 16 and 42 to get your answer. Dont forget to label!
Step-by-step explanation:
4 quarts should be one gallon because you divide 20/5 to get 4 and proportions and you get 4 quarts = 1 gallon.
You do 108 divided by 36 to get 3.

Answer:</h3>
932°F to 36032°F
<h3>
Step-by-step explanation:</h3>
Celsius and Fahrenheit are both measures of temperature. However, Celsius is a metric measurement, and Fahrenheit is used in the USA primarily.
Conversion Formula
To convert the Celsius measurements to Fahrenheit we can use the formula:
So, in this formula, you can plug in whatever Celsius value you have in and solve for Fahrenheit. To convert from F to C you can use the second formula:
Solving for Fahrenheit
Now that we have the formula, we can plug in the 2 Celsius values to find the new range.
First, plug 500°C in
Next, multiply the terms within the parentheses
Finally, add the last terms
Then, plug in 20000°C
- (20000°C × 9/5) + 32 = °F
Next, multiply the terms within the parentheses
Lastly, add the terms together
This means that, in Fahrenheit, the temperature range of the welder's electrical arc is 932°F to 36032°F. This is a total range of 35100°F.
3.2d - 4d = 2.3d + 3...simplify by combining like terms
-0.8d = 2.3d + 3....subtract 2.3d from both sides
-0.8d - 2.3d = 3 ...simplify again
-3.1d = 3...divide both sides by -3.1
d = 3/ -3.1
d = - 0.97
or
3.2d - 4d = 2.3d + 3....multiply the equation by 10, gets rid of the decimals
32d - 40d = 23d + 30....subtract 23d from both sides
32d - 40d - 23d = 30....simplify
-31d = 30...divide by -31
d = -30/31
d = - 0.97
