marble. If Marcia pulls 10 red marbles, how many blue marbles does she pull?
Answers
Answer:
She pulls 5 blue marbles
Step-by-step explanation:
Let x be the number of blue marbles
We are given that In her experiment, she finds that she is twice as likely to pull a red marble as a blue marble.
So, Number of red marbles = 2x
We are given that Marcia pulls 10 red marbles
So,
x=5
Hence She pulls 5 blue marbles

To find out how much money you received from the garage sale proceeds, you need to divide the total amount by the number of people sharing it. In this case, you and 3 friends are dividing $412 equally. So, you would divide $412 by 4 (3 friends + yourself). The money you received from the garage sale is $103.

To find out how much money you received from the garage sale proceeds, you need to divide the total amount by the number of people sharing it. In this case, you and 3 friends are dividing $412 equally. So, you would divide $412 by 4 (3 friends + yourself).
Step 1:
Divide $412 by 4 to find the equal share for each person.
Step 2:
Perform the division: $412 ÷ 4 = $103.
Step 3:
The money you received from the garage sale is $103.

Step-by-step explanation:
To solve, we need to plug in the x and y values since we already have the values given to us
1/2(4)(2^2)
We should do the exponents first, 2^2 is 4
Now we are left with 1/2(4)(4)
4 times 4 is 16
16 times 1/2 is the same as 16/2
16/2=8

To evaluate square roots, find the prime factorization. If all the exponents are even, then it is a square root! Just divide the exponents by 2, and multiply them together. To evaluate cube roots, find the prime factorization. If all the exponents are multiples of three, it is a cube root! Just divide the exponents by 3 and multiply them together.

Final answer:
Evaluating cube roots and square roots involves finding the number that, when multiplied by itself (in the case of square roots) or multiplied by itself twice (in the case of cube roots), gives us the original number.
Explanation:
In simple words, evaluating cube roots and square roots involves finding the number that, when multiplied by itself (in the case of square roots) or multiplied by itself twice (in the case of cube roots), gives us the original number. For instance, 5 is the square root of 25, as 25 is equivalent to 5 multiplied by 5. Because 27 is equal to 3 times 3 times 3, this number's cube root is 3.
