12/13 < 36/30
13/17>24/28
Answer:
The first one: 12/13 > 36/30
Step-by-step explanation:
The first one would be correct as 12/13 is less than 36/30.
To explain why 13/17 is actually less than 24/28, see below:
So when comparing fractions, we must follow steps.
Step One: convert mixed numbers to a fraction, if there are any
There are not mixed numbers to compare, so we can move to the next step.
Step Two: find the least common denominator of the two fractions
Least common denominator = 476
Check out our least common denominator calculator for help on finding this.
Step Three: rewrite each fraction to an equivalent fraction using the denominator 476
To do this, start by dividing 476 by the denominator of the first fraction. Next, multiply the result by the numerator to find the new numerator. To rewrite, put the new numerator over 476. Repeat this for the second fraction
364/476 408/476
Step Four: compare the numerators
At this point, to compare the fractions, we can simply compare the numerators to see which is larger
364<408
Step Five: rewrite each fraction as the original fraction
13/17<24/28
Therefore, the first statement (12/13 > 36/30) is true.
Answer:
12/13 < 36/30
Step-by-step explanation:
There are many ways to compare numbers. One way is to compare them to some value that lies between. Another is to consider their difference from a value that does not lie between.
12/13 vs 36/30In the first fraction, 12 < 13, so the value of the fraction is less than 1:
12/13 < 1
In the second fraction, 36 > 30, so the value of the fraction is greater than 1:
1 < 36/30
Then the order of the fractions is ...
12/13 < 1 < 36/30
12/13 < 36/30 . . . . . the given order is True
13/17 vs 24/28We notice the difference between numerator and denominator is 4 in each case, so we can write each fraction as a difference from 1:
(13/17) vs (24/28)
= (1 - 4/17) vs (1 -4/28) . . . . . fractions rewritten
= -4/17 vs -4/28 . . . . . . . . . subtract 1 from both
The first fraction, 4/17, has a smaller-value denominator, so its magnitude is larger than that of the fraction 4/28. In other words, the ordering of these fractions is ...
-4/17 < -4/28
1 -4/17 < 1 -4/28 . . . . . . add 1 to both sides
13/17 < 24/28 . . . . . the given order is False
__
Additional comment
One sort of "no brainer" way to compare the fractions is to multiply them by the product of their denominators. This looks like "cross multiplication" where each numerator is multiplied by the opposite denominator. As long as you keep the numerators in the same relative places, the comparison symbol will be the correct one for the fractions.
12/13 vs 36/30 ⇒ (12·30) vs (13·36) ⇒ 360 < 468
The left fraction is smaller than the right fraction.
Similarly, ...
13/17 vs 24/28 ⇒ (13·28) vs (17·24) ⇒ 364 < 408
The left fraction is smaller than the right fraction.
__
Here, we have used the fractions "as is." In each case, the fraction on the right could be reduced, possibly making the comparison easier.

The requried, numerator of the simplified sum is 4x + 6. The option is correct.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property
The given expression is x/(x²+3x+2) + 3/(x+1). To make the denominators the same, we need to factor the denominator of the first fraction:
x/(x+1)(x+2) + 3/(x+1)
Now we can add the two fractions by finding a common denominator, which is (x+1)(x+2):
x/(x+1)(x+2) + 3(x+2)/(x+1)(x+2)
Simplifying the numerators, we get:
x + 3x + 6 / (x+1)(x+2)
Combining like terms in the numerator, we get:
4x + 6 / (x+1)(x+2)
Therefore, the simplified expression is (4x+6)/(x+1)(x+2).

A small radio transmitter broadcasts in a 50 mile radius. If you drive along a straight line from a city 56 miles north of the transmitter to a second city 58 miles east of the transmitter, during how much of the drive will you pick up a signal from the transmitter?
Given the radius of 50 miles and the line joining the cities at (0, 56) and (58, 0), the transmitter signal can be picked during 59.24 miles of the drive.
How can the duration of signal reception be found?Radius of broadcast of the transmitter = 50 miles
Location of starting point = 56 miles north of the transmitter
Location of destination city = 58 miles east of the transmitter
Therefore we have;
Slope of the line joining the two cities
= 56 ÷ (-58) = -0.966
Which gives the equation of the line as follows;
y = -0.966•x + 56
The equation of the circle is;
[tex] {x}^{2} + {y}^{2} = {50}^{2} [/tex]
[tex] {x}^{2} + { ( - 0.966x + 56)}^{2} = {50}^{2} [/tex]
1.933156•x^2 - 108.192•x + 636 = 0
Which gives;
x = 6.67 or x = 49.29Therefore;
When x = 6.67, we have;
y = -0.966 × 6.67 + 56 = 49.56When x = 49.29, we have;
y = -0.966 × 49.29 + 56 = 8.4The length of the drive, during which the driver can pick the signal, l, is therefore;

Find the area of the shaded region.
The outside of the figure is a rectangle that is 24 inches long and 8 inches high. The entire rectangle is shaded except for a triangle with a base of 24 inches and a height of 8 inches.
Answer:
96 sq. inch
Step-by-step explanation:
rectangle has 24 inches × 8 inches dimensions
Hence, Area of Rectangle,
A1=24×8
=192 sq. inch
We, know triangle with base 24 inches and height 8 inches has area exactly half of the rectangle's.
ie. A2=½(24×8)
=96 sq. inch
This was for unshaded region. Then remaining half area is for shaded region.
A1-A2=A
ie. 192-96=96 sq. inch
The area of the shaded region is 96 square inches.
How to determine the area of the shaded regionTo find the area of the shaded region, we need to subtract the area of the triangle from the area of the rectangle.
The area of a rectangle is calculated by multiplying its length by its width. In this case, the rectangle has a length of 24 inches and a width of 8 inches, so its area is 24 inches * 8 inches = 192 square inches.
The area of a triangle is calculated by multiplying its base by its height and dividing the result by 2. In this case, the triangle has a base of 24 inches and a height of 8 inches, so its area is (24 inches * 8 inches) / 2 = 96 square inches.
Now, to find the area of the shaded region, we subtract the area of the triangle from the area of the rectangle:
Shaded Area = Area of Rectangle - Area of Triangle
= 192 square inches - 96 square inches
= 96 square inches
Therefore, the area of the shaded region is 96 square inches.

You will need____ mL of pure water to obtain___ mL of the desired 25% solution.
You will need 252 mL of pure water to obtain 0.25 mL of the desired 25% solution.
If we add X amount of water to the solution, the total amount of solution is 375+X.
And that must be 25%.
What is the amount of solute in the current solution?
The amount of solute in the current amount of solution is
0.6(375)=225.
That amount won't change by adding water.
So we set up the equation so that the amount of solute divided by the new total amount of solution equals 25%.
225/(375+X)=0.25
cross multiply and solve
225/0.25=(375+X)
900-375=X

The equation of the line in slope-intercept form that passes through the point (-6, -5) with a slope of 6 is y = 6x + 31. The correct answer is option (D).
Given that the line passes through the point (-6, -5) with a slope of 6, we can plug these values into the equation to find the y-intercept (b).
Using the point-slope form of the equation:
y - y₁ = m(x - x₁)
Substitute (-6, -5) and the given slope (m = 6):
y - (-5) = 6(x - (-6))
y + 5 = 6(x + 6)
Now, let's simplify the equation:
y + 5 = 6x + 36
To get the equation in slope-intercept form (y = mx + b), isolate y:
y = 6x + 36 - 5
y = 6x + 31
