Answer:
D) division
Step-by-step explanation:
we know that a ratio is a quantitative relation between two numbers
so let's say
the ratio of boys to girls is 3:4
we know that for every 3 boys there are 4 girls
therefore it is a division operation
Okay, so total dogs are 49.
So we know if x=large dogs and y=small dogs, then x+y=49.
Next we are told that there are 36 MORE small dogs than large dogs. We can take that more meaning addition, and x being our value for large dogs. So y=x+36.
After that we now know what value we can plug in for y. So x+x+36=49.
We can then simplify it to 2x+36=49.
Subtracting the 36 from both sides, leaves you with 2x=13.
Followed by dividing both sides by 2, gives you x=6.5. Or 6.5 large dogs.
Now we can plug this into our formula for the small dogs (y=x+36) to give us y=6.5+36, which simplifies to y=42.5. Or 42.5 small dogs. Which is our answer.
We can double check it by adding the small and large dogs together, 6.5+42.5, which gives us 49, our total entries.
Answer:
34/4 = 8.5 dollars per hr
12 x 8.5 = 102
Answer: $102
Step-by-step explanation:
First step: find the unit rate (how much she earns per hour )
34/4 = 8.5
Next: Find how much she wants to work for
Then: Create the equation.
12 x 8.5
Last: multiply 12 and 8.5 and you should get your answer of 102 dollars
REMEMBER TO ADD THE DOLLAR SIGN
Answer:
Probability[Prime number] = 1/3
Step-by-step explanation:
Given:
Total number between 13 to 21;
13, 14, 15, 16, 17, 18, 19, 20, 21
Find:
Probability[Prime number]
Computation;
Total number between 13 to 21 = 9
Total number of prime number;
13, 17 ,19
Total number of prime number = 3
Probability pf event = Number of favorable output / Total output
Probability[Prime number] = Total number of prime number / Total number between 13 to 21
Probability[Prime number] = 3 / 9
Probability[Prime number] = 1/3
Answer:
I think the relationship is proportional.
