Answer:
The answer is actually a proper fraction = 7/20
Step-by-step explanation:
A mixed fraction is expressed as : a b/c
Let the mixed fraction be represented by Y
a) The fraction is halved
= Y ÷ 1/2 = Y/ (1/2)
In mathematics, when we divide a number by a fraction, the number is multiplied by the reciprocal of the fraction.
Y × 2 = 2Y
b) Then 3/4 is added
= 2Y + 3/4
c)The result is 1 9/20
2Y + 3/4 = 1 9/20
Converting the mixed fraction to improper fraction, we have
1 9/20 = (20 × 1) + 9/ 20 = 29/20
Therefore,
2Y + 3/4 = 29/20
2Y = 29/20 - 3/4
The Lowest common multiple of the right hand side = 20
2Y = (29 - 3×5)/ 20
2Y = 29 - 15/20
2Y = 14/20
2Y = 7/10
To find Y , we cross multiply
2Y × 10 = 7
20Y = 7
Y = 7/20
Therefore, the mixed fraction represented by Y is actually a proper fraction = is 7/20
Answer:
a = 1
b = 2
c = 5
Step-by-step explanation:
Given
Mixed fraction: a b/c
Result after arithmetic operations = 1 ⁹/20
Required.
Find a, b, c
From the question, the fraction is halved. This is represented as follows
a b/c ÷ 2
= a b/c * ½
Then, ¾ is added. This is represented by
a b/c * ½ + ¾
The result is 1 ⁹/20. This is represented by
a b/c * ½ + ¾ = 1⁹/20
Convert mixed fraction to improper fraction
a b/c * ½ + ¾ = 29/20
Subtract ¾ from both sides
a b/c * ½ + ¾ - ¾ = 29/20 - ¾
a b/c * ½ = (29 - 15)/20
a b/c * ½ = 14/20
a b/c * ½= 7/10
Multiply both sides by 2
2 * a b/c * ½= 7/10 * 2
a b/c = 14/10
a b/c = 7/5
Convert mixed fraction to improper fraction
a b/c = 1⅖
By comparison,
a = 1
b = 2
c = 5

The Answer Is 9
Step-by-step explanation:
0.5(3)(6)
1.5(6)
9
Answer:
9
Step-by-step explanation:
I chose 9 because first you have to add 4+2 because it's in parenthesis and the other with parenthesis has no other numbers so 4+2 first then 4+2 is 6 then you multiply 6 by the 3 in the parenthesis because it is in the parenthesis then divide by 2 because 1/2 is basically dividing by 2

What is the measure of an angle, in degrees, if its supplement is six times its complement?
Answer:
72 degrees.
Step-by-step explanation:
We can name the measure of the angle x.
We can name the measure of the complement of it y.
Note that complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees.
Using this info, we can set up two equations.
x+y=90
x+6y=180
Subtract the first equation from the second to eliminate x. You can do both ways, but I prefer to keep the equation positive.
x+6y=180
-x -y -90
5y=90
Divide both sides by 5.
y=18
The complement is 18, now we can plug that in to find x.
x+18=90
Subtract 18 from both sides.
x=72
The measure of the angle is 72 degrees.
Please help!
In the figure, b and c are parallel lines. Which of the following statements are true?
1.Joe claims the measure of angle 3 is equal to 90 degrees. Is he correct, why or why not?
2.state the measure of angle 5 and how you know!
Here is the figure thank you for any help!! :)
Given the general form: ax + by = c How can we rewrite this general for the equation of a line, so that it is in slope intercept form? (a, b, and c are real numbers other than 0.) Hint: Substitute in values for a,b,c if you are confused) YOUR FINAL ANSWER SHOULD HAVE a,b,c in it. *
Answer:
[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex] or [tex]y = \frac{c-ax}{b}[/tex]
Step-by-step explanation:
Slope intercept form is y = mx + b, so you rewrite it to equal y.
ax + by = c
by = c - ax
y = (c - ax) / b
[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex]
In the image, all the lines overlap. This proves that all the equations are equal to each other.
hi got a question!
convert 20 m\s into km\hr ?
HELPPP!! PLEASEEE!
AND THANK YOUUUU
Answer: 72 km / hour
Step-by-step explanation:
Answer:
72 km/hr
Step-by-step explanation:
First, convert from meters to kilometers. 20 meters is 0.02 kilometers.
Now that you have km/s, convert 0.02 km/s into km/h by multiplying it by the number of seconds in an hour. There are 3,600 seconds in an hour. Multiply 0.02 km/s by 3,600 secs/h to get 72km/h!

mile in 3 minutes and 15 seconds. Calculate Jose's rate in minutes per mile; in other words, the time that it would take for him to run 1 mile.
Answer:
you have to find the unit rate first then try to solve
Step-by-step explanation:
Answer:
1/4 minutes
Step-by-step explanation:
1 minute = 60 seconds
3 minutes = 180 seconds
3 minutes and 15 seconds = 195 seconds
13 miles/195 seconds
195/13 = 15
His speed --> 1 mile/15 seconds
1/4 minutes = 15 seconds

Find the mean absolute deviation for the set below:
62, 71, 83, 110, 501, 94, 227
Answer:
(MAD) mean absolute deviation: 114.2
Step-by-step explanation:
Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164
164 - 62 = 102
164 - 71 = 93
164 - 83 = 81
164 - 110 = 54
164 - 501 = 337
164 - 94 = 70
164 - 227 = 63
Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 = 114.2
Answer:
Step-by-step explanation:
First, add all the numbers and count the total amount of numbers.
Once you've done that find the mean by dividing the total of the numbers by how many numbers you have.
Next make a chart, have 2 parts in the chart. Make boxes for however many numbers you have. Make another row in the chart for the distance from the mean ( how many numbers is it from the mean.)
Add all the "distance from mean" numbers and divide by total numbers, If a decimal, round up or down.
Then, you have the M.A,D ( Mean Absolute Deviation )

Answer:
no 6^2 + 8^2 ≠ 12^2 so this is not a right triangle
Step-by-step explanation:
The Pythagorean theorem tells you if you have a right triangle
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + 8^2 = 12^2
36+64 = 144
100 = 144
This is not true so this is not a right triangle

Find the value of x.
F) 6m
G) 7.5m
H) 15m
I) 21m
Answer:
x = 6 m
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here A = 60, h = 8, a = 9 and b = x , thus
[tex]\frac{1}{2}[/tex] × 8 × (9 + x) = 60, that is
4(9 + x) = 60 ( divide both sides by 4 )
9 + x = 15 ( subtract 9 from both sides )
x = 6 m
