what is this: 9/5 - 1/3
Answer:
22/15 in fraction 1 7/15
Step-by-step explanation:
Answer:
___________
Exact Form:
22 / 15
Decimal Form:
1.46 continuous
Mixed Number Form:
1 7/15
To write 9/5 as a fraction with a common denominator, multiply by 3/3
9/5 x 3/3 - 1/3
To write −1/3 as a fraction with a common denominator, multiply by 5/5.
9/5 x 3/3−1/3 x 5/5
Write each expression with a common denominator of 15, by multiplying each by a factor of 1
Multiply 9/5 and 3/3
9 x 3/5 x 3 - 1/3 x 5/5
Multiply 5 by 3
9 x 3/15 − 1/3 x 5/5
Multiply 1/3 and 5/5
9 x 3/15 − 5/3 x 5
Multiply 3 by 5
9 x 3/15 − 5/15
Then combine the numerator over the common denominator
9 x 3 - 5 / 15
then simplify the numerator
mutiply 9 by 3
27 - 5/15
subtract 5 from 27
22/15
It's a word problem junkie. Is a bus driver who earns 1600 dollars per month login is a is a manager who earns 6800 dollars per month. In 2012 Jun bro donated a total of 1200 dollars to charity while login donated4500dollars to charity who donated the higher percentage of money
Answer: bus driver
Step-by-step explanation:
Given: Earning of bus driver = 1600 dollars per month
Earning of manager = 6800 dollars per month
Amount donated by bus driver = 1200 dollars
Amount donated by manager = 4500 dollars
Percentage of amount donated by bus driver = [tex]\dfrac{1200}{1600}\times100 \%=\dfrac{3}{4}\times100\%=75\%[/tex]
Percentage of amount donated by manager = [tex]\dfrac{4500}{6800}\times100 \%\approx66.18\%[/tex]
Clearly, 75> 66.18
So, bus driver donated higher percentage of money.
Point H is between points L and S. LS = 14x -21 LH = 15 HS = 8x What is the length of segment LS?Immersive Reader (5 Points)
Answer:
[tex]LS = 63[/tex]
Step-by-step explanation:
Given
[tex]LS = 14x - 21[/tex]
[tex]LH = 15[/tex]
[tex]HS = 8x[/tex]
Required
Determine the length of LS
Since H is between L and S, then
[tex]LS = LH + HS[/tex]
Substitute 14x - 21 for LS, 15 for LH and 8x for HS
[tex]14x - 21 = 15 + 8x[/tex]
Collect Like Terms
[tex]14x - 8x = 21 + 15[/tex]
[tex]6x = 36[/tex]
Divide both sides by 6
[tex]x = 6[/tex]
Substitute 6 for x in [tex]LS = 14x - 21[/tex]
[tex]LS = 14(6) - 21[/tex]
[tex]LS = 84 - 21[/tex]
[tex]LS = 63[/tex]
Hence, the length of LS is 63 units
which of the following units is incommensurable with kilograms? A.pounds B.ounces C.tons D.gallons
Answer: D.gallons
Step-by-step explanation:
Kilogram is a unit of mass
Now, Pounds, Tons and Ounces are also units of mass.
But Gallons is a unit of volume, where 1 gal = 3.785 L
Then you never can represent an amount of mass using units for volume, which means that gallons is incommensurabe with kilograms.
the correct option is D

#1) Select the lie from the dropdown below.
A)
All real numbers are
whole numbers.
B)
All whole numbers are
real numbers
C)All integers are rational
numbers.
Int.
Answer:
A
Step-by-step explanation:
Think of this always
Whole Numbers > integers > rational numbers > Real numbers
Not all real numbers are whole numbers. It could be and integer like 1.5 which is a real number but not a whole number. So A is lying.
Answer:
The Answer is A.
Step-by-step explanation:
All numbers are real numbers but not all real numbers are a whole. I can't give any further explanation but this is what we were taught when I was younger so it should be correct.

Simplify the square root of negative 18
Answer:
[tex]3i\sqrt{2}[/tex]
Step-by-step explanation:
If we have the expression [tex]\sqrt{-18}[/tex], we can divide -18 by 2.
[tex]\sqrt{2\cdot-9}[/tex]
The square root of 9 is 3, and since we’re finding the square root of a negative number, we append the “i” to the term: so 3i.
This goes outside the root, making the expression [tex]3i\sqrt{2}[/tex].

4m-3/4=-9+4m/8 this is my question that i need help with
Answer:
The answer is -2 5/14 if you're trying to solve for m
Step-by-step explanation:
first you get rid of the fractions by mutiplying both sides by 4.
4(4m-3/4)=(-9+4m/8)4
16m-3=-36+2m then you put the varible terms on one side and the numbers on one side
14m=-33
then divide -33 by 14
which will give you the fraction -2 5/14 unless you want decimal form which would be around -2.36
Answer:
[tex]m=-\frac{33}{14}[/tex]
Step-by-step explanation:
[tex]4m-\frac{3}{4}=-9+\frac{4m}{8}[/tex]
[tex](4m-\frac{3}{4})8=(-9+\frac{4m}{8})8[/tex] multiply by 8 to get rid of the largest denominator
[tex]32m-\frac{24}{4}=-72+4m[/tex]
[tex]32m-6=-72+4m[/tex]
[tex]32m-4m=-72+6[/tex] Rearrange the equation and Collect like-terms
[tex]28m=-66[/tex]
[tex]m=-\frac{66}{28}[/tex] simplify
[tex]m=-\frac{33}{14}[/tex]
the larger of two numbers is 4 more than the smaller the sum of the two numbers is 74
Answer:
y = 35 x = 39
Step-by-step explanation:
Let large no = x and small no = y
According to the question,
x = 4 + y ------ (1)
x + y = 74 -------- (2)
Substituting (1) in (2)
( 4 + y ) + y = 74
4 + 2y= 74
2y = 74 -4
y = 70 / 2 = 35
x = 4 + y
= 4 + ( 35 )
= 39

The midpoint between two points is( 1 , 5 ). One of those points is ( 9 , 3 ), find the other. DUE in 2 HOURS, will give Brainliest! A. (4, - 1) B. (-4, 1) C. (5, 4) D. (-7, 7)
Answer: (-7, 7)
Step-by-step explanation:
Answer:
[tex]\mathrm{Solution\:} = (- 7,7) = \mathrm{Last\:}\mathrm{Option\:}[/tex]
Step-by-step explanation:
In my point of view the easiest approach to solving this problem would be by determining the distance between the given points (the midpoint and the other given point) --- (1) and then going through all the answer choices and matching their distance to the midpoint --- (2). This may seem like a hard approach, but you can eliminate many of the answer choices.
The answer is the last choice, so let's prove it.
[tex]\mathrm{Distance\:between\:}\left(1,\:5\right)\mathrm{\:and\:}\left(9,\:3\right) = \sqrt{\left(9-1\right)^2+\left(3-5\right)^2} = 2\sqrt{17}[/tex]
[tex]\mathrm{Distance\:between\:}\left(1,\:5\right)\mathrm{\:and\:}\left(-7,\:7\right)=\sqrt{\left(-7-1\right)^2+\left(7-5\right)^2}=2\sqrt{17}[/tex]
[tex]2\sqrt{17} = 2\sqrt{17}[/tex]
As the distance between points (1,5) and (9,3) respectively (1,5) and (- 7,7) is the same, we proved that our answer is the last choice.
Evaluate the expression. 34 -8 - 14 + 2 + 5
Answer:
About 20
{19 exactly}
Step-by-step explanation:
Evaluate means find approximate value without exact calculation (usually done with great numbers or with fractions)
-8 is approximately -(2+5) so the sum is about 0
34-14 = 30-10 = 20
20 + 0 = 0
The exact calculation would be:
34 -8 - 14 + 2 + 5 = 34 - 14 - 8 + 7 = 20 - 1 = 19
Jade and Ali set the alarms on their phones to sound at 7.15 am.
Both alarms sound together at 7.15am.
Jade's alarm then sounds every 40 minutes.
Ali's alarm then sounds every 60 minutes.
At what time will both alarms next sound together?
Answer:
9:15 am
Step-by-step explanation:
Alarms sound at 7:15 am
Alarm frequencies are 40 min and 60 min
Since 40= 20*2 and 60= 20*3, the overlapping frequency is:
20*2*3= 120 min = 2 hoursSo next time both alarms sound at 7:15 am + 2 hours = 9:15 am
Answer:
Trust me its 9:15 am

translating verbal expressions: 3 less than the square of a number p
Answer: p²-3
Step-by-step explanation:
3 less than the square of a number p=p²-3
When coming across [a less than b], this means b-a.
If you are pretty confused with this variable expression, I will provide to you with some numerical examples.
3 less than the square of 4=4²-33 less than the square of 10=10²-3This pattern will also apply for p
Brent knows that the six digit number he uses to open his computer is the prime factorization of 5005 if each digit of the code increases from left to right
Answer:
The code is 571113
Step-by-step explanation:
The problem requires that we find the prime factors of 5005
1. 5005 is a multiple of 5 since it ends with a number 5
5 is one of the numbers
Dividing 5005/5 = 1001
the next prime number after 5 is 7
so 1001/7= 143
7 is one of the numbers
the next prime number after 7 is 11
so 143/11= 13
13 is one of the numbers
In all the prime factorization of 5005 is found as follows
5,7 11,13
Combining these numbers gives the 6 digit code
571113
