WHAT ARE ALL PRIME NUMBERS X WHICH ARE [tex]5\ \textless \ x\leq 19[/tex]
WHOEVER ANSWERS FIRST AND CORRECTLY IS BRAINLIEST
Answer:
7, 11, 13, 17, 19
All of these numbers only have 1 and themselves as factors, and every other number can be written as a product of two or more primes, making the remaining number composite:
[tex]6=2\cdot3\\8=2^3\\9=3^2\\10=2\cdot5\\12=2^2\cdot3\\14=2\cdot7\\15=3\cdot5\\16=2^4\\18=2\cdot3^2[/tex]
The prime numbers that X could be are 7, 11, 13, 17, and 19.

In an office,2/3 of the telephone bill is paid by Tom,1/5 paid by Azuma and the remaining by Tina. What fraction is paid by Tina?
Answer:
4/15
Step-by-step explanation:
1 - 2/3 = 1/3
1/5 x 1/3 = 1/15 of the bill
1/15 of bill is paid by azuma
10/15 is by tom
so 1 - 10/15 - 1/15 = 4/15 by tina
3/7 of the students in a school are in sixth grade. a) How many sixth graders are there if the school has 70 students? 7 b) How many sixth graders are there if the school has 28 students?
Answer:
a) 30 sixth-graders
b) 12 sixth-graders
Step-by-step explanation:
You can solve this problem by multiplying fractions. In order to solve a, you need to multiply 3/7 by 70 students to e t the number of sixth-graders because 3/7 of the population (in this case it's 70) are 6th graders:
70 × 3 ÷ 7 = 70 ÷ 7 × 3 = 30
So if the school has 70 students, 30 are 6th graders.
For part b, you multiply the student population (28) by the ratio 3/7 to find how many 6th grader there are:
28 × 3 ÷ 7 = 28 ÷ 7 × 3 = 12
So if the school has 28 students, 12 are 6th graders.
a) There are 30 sixth graders are there if the school has 70 students.
b) There are 12 sixth graders are there if the school has 28 students.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
3/7 of the students in a school are in sixth grade.
Now,
a) Let the students in school = 70
Then, Number of students in sixth grade = 3/7 × 70
= 3 × 10
= 30
b) And, Let the students in school = 28
Then, Number of students in sixth grade = 3/7 × 28
= 3 × 4
= 12
Thus, a) There are 30 sixth graders are there if the school has 70 students.
b) There are 12 sixth graders are there if the school has 28 students.

Javier and his family drink 3 gallons of milk each week. Javier drinks 5 quarts of milk each week. How many pints of milk does the rest of his family drink during the week?
A.12
B.14
C.7
D.10
Answer:
So basically Javier and his family drink a total of 12 quarts of milk each week because 1 gallon of milk is 4 quarts so Javier drinks 5 quarts 12-5=7
which leaves 7 quarts for his family. 2 pints are equal to a quart therefore 14 pints are left for his family

what is 0.000036÷180 in standard form
Answer: 36/1000000 is the pq form of the given no..
Step-by-step explanation:
The standard form of 0.000036÷180 is 2 × [tex]10^{-7}[/tex] .
How do you express a number in standard form?Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. 1.23 × [tex]10^{8}[/tex]; If you observe carefully, 1.23 is a decimal number between 1.0 and 10.0 and so we have the standard form of 123,000,000 as 1.23 × [tex]10^{8}[/tex].
According to the question
0.000036÷180 in standard form
Now,
0.000036÷180
= [tex]\frac{0.000036}{180}[/tex]
= 0.0000002
= [tex]\frac{2}{10000000}[/tex]
= 2 × [tex]10^{-7}[/tex] is the standard form .
Hence, the standard form of 0.000036÷180 is 2 × [tex]10^{-7}[/tex] .

Can someone please help me with 2 math questions.
1. A TV is on sale for $399, or 16% off. What was the original price of the TV? Show your work.
2. A computer is on sale for $450.50, or 15% off. What was the original price of the computer? Show your work.
Answer:
Step-by-step explanation:
1) $399 = 84% of the original amount
Divide both sides by 84 to get what one percent would be
$4.75 = 1%
Then multiply both sides to get one hundred percent [the original price]
$475 =100%
Use this method to do the second question
$450.50 = 85%
Divide by 85
$5.30 = 1%
Multiply by 100
$530 = original price

Need help with the correct answer please! Thank you. Which two triangles are congruent by the SSS Theorem? I picked D but that is the wrong answer.
Answer:
B
Step-by-step explanation:
RQ=TV
QS=VU
RS=TU
While proving that 2 triangles are congruent you have to consider the same side for both triangles.
The mistake you made was that you presumed that since both have equal sides they are equal,
In a sense that is true but you have align it in the correct way, in option D) it shows RQ is equal to TU which is wrong, RQ is equal to VT, you have align it in a proper way.
B) ΔRQS ≅ ΔTVU here it is align perfectly to be matched

Joe and John have Repair shops. Joe charges $11.25 per hour for repairs. The table below show's John's rate: Who earns more money per hour? How much more money does that person charge per hour?
Answer: John earns $0.25 more an hour than Joe does.
Step-by-step explanation: 3 hours is equivalent to $34.50 in payouts, meaning in order to get the hourly charge you would have to divide 34.50 by 3. Which is 11.5 or 11.50. 11.25 is 0.25 below 11.50. Hope this helps! :)
Kaylee works at Claire's Jewelry Store at the mall. She earns $7.75 per hour. She earned $93.00 over the weekend. Her final check for the week was $232.50 (before deductions). How many hours did she work in addition to the weekend hours?
Answer:
18 hours during the week days
Step-by-step explanation:
weekend pay + week day pay = total pay
93 + week day pay = 232.50
Subtract 93 from each side
93-93 + week day pay = 232.50-93
week day pay = 139.50
She makes 7.75 per hour
139.50 = hours * pay rate
139.50 = hours*7.75
Divide each side by 7.75
139.50/7.75 = hours
18 = hours
