One winter night the temperature fell 16 degrees between midnight and 5 A.M. By 9 A.M.the temperature had doubled from what it was at 5 A.M. By noon, it had risen another 12 degrees to 30 degrees. What was the temperature at midnight?
The temperature at midnight was 25 degrees.
We have at one winter night the temperature fell 16 degrees between midnight and 5 A.M. By 9 A.M. the temperature had doubled from what it was at 5 A.M. By noon, it had risen another 12 degrees to 30 degrees.
We have to determine the temperature at midnight?
What is Temperature ?Degree of hotness or coldness measured on a definite scale is called Temperature. When the temperature of the body is high it is called hot body and when it is low it is called cold body.
According to the question -
Assume the temperature at mid - night be x and at 5 AM be y.
Then -
x - y = 16
At 9 A.M. , assume the temperature to be z. Then -
z = 2y
At Noon -
z + 12 = 30
z = 30 - 12
z = 18 degree
At 9 A.M., we have -
z = 2y
18 = 2y
y = 9 degrees
At mid - night, we have -
x - y = 16
x - 9 = 16
x = 25 degrees
Hence, the temperature at midnight was 25 degrees.

What percent of 86 is 50 to the nearest whole percent
Answer:
58%
Step-by-step explanation:
Let us suppose x percent of 86 is 50.
Therefore, we have the below equation
x% of 86 = 50
Eliminating percentage, we get
0.0x × 86 = 50
Solve for x
[tex]0.0x\times86=50\\\\0.0x=\frac{50}{86}\\\\x=\frac{50}{86}\times100\\\\x=58.1[/tex]
Hence, in nearest whole percent, we have
x = 58%
Therefore, 58% of 86 is 50
Charles will babysit for up to 4 hours and charges $7 per hour. Write a function in function notation for this situation.
Answer:
The function is [tex]C(x)=7x[/tex]
Step-by-step explanation:
Given : Charles will babysit for up to 4 hours and charges $7 per hour.
To find : Write a function in function notation for this situation ?
Solution :
Let the work done by Charles in 'x' hour.
The charges is $7 per hour.
To create a function of x,
The cost function of 'x' hour is [tex]C(x)=7x[/tex]
Charles will babysit for up to 4 hours.
So, The cost for 4 hour is [tex]C(x)=7\times 4[/tex]
[tex]C(x)=\$28[/tex]

how many times can 16 go into 50
Which equation can be used to find one or more factors of 26
The factors of 26 are one, two, 13 and 26. One and the number itself, in this case 26, are always factors. Since 26 is an even number, which means that it ends in zero, two, four, six or eight, it's evenly divisible by two. Two times 13 equals 26.
No numbers between two and 13 divide evenly into 26, so there are no more factors other than the four listed. Because two and 13 are both prime numbers, which are numbers that are only divisible by one and themselves, the prime factorization of 26 is 2 x 13. The prime factorization of a number refers to the prime numbers that multiply together to make that given numberhow are rates and ratios related?

Josh is 4 years older than Delaney. In 5 years the sum of their ages will be 60. How old is Josh now?
Final answer:
The problem is a middle school mathematics question about algebra and age. By setting up an equation and solving it, we found that Josh is currently 27 years old.
Explanation:
The subject of this question is Mathematics, and it is likely a Middle School level problem. To solve this, we set up an equation based on the information provided: Let's denote Delaney's current age as D. According to the question, Josh is 4 years older than Delaney, so Josh's current age is D + 4 years. In 5 years, Delaney will be D + 5 years old, and Josh will be (D + 4) + 5 which simplifies to D + 9 years old. We know that the sum of their ages in 5 years will be 60. Therefore, the equation is:
D + 5 + D + 9 = 60
Combining like terms, we get:
2D + 14 = 60
Subtracting 14 from both sides, we get:
2D = 46
Divide both sides by 2 to find Delaney's current age:
D = 23
Now, we can determine Josh's current age by adding 4:
Josh's age = D + 4 = 23 + 4 = 27
Therefore, Josh is currently 27 years old.

The product of 5 and a number x is 14 .
What is the value of x?
x=194
x=120
x=54
x=434
none of them.
Product means multiplication, so the product of 5 and a number means 5 times a number which is 5x
so if 5x = 14
x = 14/5 = 2.8
x = 2.8 which isn't a choice.
Answer:
The answer is B 1/20
Step-by-step explanation:
The word "Product" means multiplication, and we need to find the value of "x" here's an equation:
5 times x = 1/4
5 times 1/20 = 1/4

The sign of the product of two integers with the same sign is positive. What is the sign of three integers with the same sign? Explain your thinking.
Answer:
Negative.
Step-by-step explanation:
The answer is negative, because if the number of integers you are multiplying is odd, then the sign is negative. But if the number of integers you are multiplying is even, then the sign is negative. In this case, three is odd, so the sign is negative.

Mrs. Synder must choose two of her homeroom students to be class representatives. The class consists of 13 girls and 9 boys. Approximately what percent chance is there that the first student chosen is a boy and the second student chosen is a girl? (Round to the nearest percent)
A. 10%
B. 25%
C. 22%
D. 15%
Answer: B. 25%
Step-by-step explanation:
Given : Number of boys in the class = 13
Number of girls in the class = 9
Total students = 13+9=22
Now, the number of ways to choose first boy then a girl =[tex]13\times9=117[/tex] (1)
Number of ways to choose nay two students :-
[tex]{22}P_{2}=\dfrac{22!}{(22-2)!}\\\\=\dfrac{22\times21\times20!}{20!}=462[/tex] (2)
Now, the probability that the first student chosen is a boy and the second student chosen is a girl :-
[tex]\dfrac{117}{462}=0.253246753247\approx0.25[/tex] [Divide (1) by (2)]
In percent , [tex]0.25\times100=25\%[/tex]
Hence, approximately 25% chance that the first student chosen is a boy and the second student chosen is a girl.
