From midnight until 8:00 AM, the temperature tripled and then rose 5 degrees. The temperature at 8:00 AM was –7 degrees Celsius. Write and solve an equation to find the temperature at midnight.

Answers

Answer 1

Answer:

The equation of the temperature at midnight is written as 3y + 5 = -7

The temperature at the midnight is calculated to be -4 degrees

How to write the equation of the temperature at midnight

The equation for the temperature at midnight is following the information given in the problem tripled and increased by 5

Assuming the temperature at midnight is y. For the temperature to triple we have

For the temperature to rise 5 degrees will result to

3y + 5 = -7

solving for y

3y + 5 = -7

3y = -7 - 5

3y = -12

y = -4

At midnight the temperature was -4 degrees

What composite number is greater than 1000 whose prime factorization contains 1 prime number that does not repeat 1 prime number that repeats three times and 1 prime number that repeats twice?

Answers

Final answer:

The composite number sought is 12250 which is greater than 1000. Its prime factorization includes the prime numbers 2 (that does not repeat), 5 (that repeats thrice), and 7 (that repeats twice).

Explanation:

The subject is looking for a composite number greater than 1000, whose prime factorization contains 3 types of prime numbers: one that does not repeat, the second repeats three times, and the third repeats twice. We have many prime numbers but to get a number greater than 1000, let’s use larger prime numbers for instance 2, 5 and 7. Let's calculate the composite number with these primes:

2^1 * 5^3 * 7^2 = 2 * 125 * 49 = 12250

Therefore, 12250 is a composite number greater than 1000 whose prime factorization contains 1 prime number(2) that does not repeat, 1 prime number(5) that repeats three times and 1 prime number(7) that repeats twice.

I have a 96 in class and i get a 75 on a assignment that’s worth 10% whats my grade?

Answers

Answer:

Step-by-step explanation:

That would either be a B or a C!

Answer:

To calculate your overall grade, we can use the weighting of each component. Since the assignment is worth 10% of your grade, we can calculate its contribution using the following formula:

(96 * 90%) + (75 * 10%)

First, we multiply your current grade of 96 by 90% (which represents the remaining 90% of your grade) to calculate its contribution. Then, we multiply your assignment grade of 75 by 10% to calculate its contribution. Finally, we add these two contributions together:

(96 * 90%) + (75 * 10%) = 86.4 + 7.5 = 93.9

Therefore, your grade after receiving a 75 on an assignment worth 10% would be approximately 93.9%.
