PLEASE HELP!!!!! And explain too! Thanks!!! I am a prime number between 40 & 50. If you add one to me, the sum of ALL prime factors of that composite number is 15. What number am I?
Answers
I don't know any slick way to do this. I would just list the prime numbers
between 40 and 50 and test them one at a time.
The prime numbers between 40 and 50 are: 41, 43, 47
Test 41:
-- add 1 . . . 42
-- prime factors of 42 . . . 2, 3, 7
-- sum of the factors . . . 12
Test 43:
-- add 1 . . . 44
-- prime factors of 44 . . . 2, 11
-- sum of the factors . . . 13
Test 47:
-- add 1 . . . 48
-- prime factors of 48 . . . 2, 3,
-- sum of the factors . . . 5
Maybe I'm not understanding how to list prime factors, but so far,
I haven't found any number that answers the question.
Maybe if I write the prime factorization of 44 like this:
44 = 2 * 2 * 11
Now the items in the prime factorization do add up to 15.
So the answer would seem to be 43.

Answer: (–1)(525) and (35)(–15) are equivalent to (- 7) (-15) (- 5)
Step-by-step explanation:
Given (- 7) (-15) (- 5)
To Find : Which two expressions that are equivalent (- 7) (-15) (- 5)
(–7)(–75) and (–1)(525)
(–1)(525) and (35)(–15)
(35)(–15) and (115)(–5)
(–1)(525) and (115)(–5)
Solution:
(- 7) (-15) (- 5)
= (105)(-5)
= - 525
(–7)(–75) and (–1)(525)
= 525 & - 525
not Equal
(–1)(525) and (35)(–15)
= -525 and - 525
Both Equal to (- 7) (-15) (- 5)
(35)(–15) and (115)(–5)
= -525 and - 575
not Equal
(–1)(525) and (115)(–5)
= -525 and - 575
not Equal
(–1)(525) and (35)(–15) are equivalent to (- 7) (-15) (- 5)
Final answer:
The pair of expressions equivalent to (Negative 7) (Negative 15) (Negative 5) are (Negative 7) (Negative 75) and (Negative 1) (525) because both pair of expressions result in -525.
Explanation:
The question asks which pair of expressions are equivalent to the expression (Negative 7) (Negative 15) (Negative 5). For this, we need to remember the rule in mathematics that the multiplication of two negative numbers gives a positive result and the multiplication of three negative numbers gives a negative result.
So, (Negative 7) (Negative 15) (Negative 5) equals to -7*15*5 = -525. Now, among the given options, the pair of expressions that are equivalent to -525 are (Negative 7) (Negative 75) and (Negative 1) (525), because -7*75 also equals -525, and -1*525 equals -525 as well.
Therefore, the pairs of expressions equivalent to (Negative 7) (Negative 15) (Negative 5) are (Negative 7) (Negative 75) and (Negative 1) (525).

All you have to do is multiply 10 x 407.7 = 40.77 which is the answer.
But if you want to do it an a easier way you just move the decimal point one time to the left to get your answer so you wont need to use a calculator to figure that out.
Hope that helped!!

The answer is 4077. All we have to do to find the answer is do inverse operations. Since the opposite of division is multiplication we would have to multiply 407.7*10 which equals 4077. To check our answer we simply divide 4077/10 =407.7 and we find that it matches! Hope this helps!

let's firstly convert the mixed fractions to improper fractions.
Answer: 4 tablespoons of kernels.
Step-by-step explanation: Use proportions, so (1 1/2)/(2 1/4) = x/6.
You would do (1 1/2) * 6 = 9 (or 3/2 * 6). And then 9 / (2 1/4) (or 9 * 4/9 because of keep change flip) and get 4. 36/9 = 4.

So, 5 to the third power, or 5 cubed, or simply 5³, is equal to 5 x 5 x 5.
We get 125.
Now multiply 125 by 25.
Our final answer is 3125.
The value of expression which is expressed as "5 to the third power times 25" is 3125.
To calculate the value of the expression "5 to the third power times 25," we start by finding the value of 5 raised to the power of 3. This means multiplying 5 by itself three times: 5 × 5 × 5. The result is 125.
Next, we multiply this result by 25. Multiplying 125 by 25 gives us 3125. Therefore, the value of the expression "5 to the third power times 25" is 3125. This means that when we raise 5 to the power of 3 and then multiply it by 25, we get the final result of 3125.
Therefore, the required value is 3125.
