What is a rational number?A rational number is a number that can be written in the form of p/q where q is not equal to zero.
We have,
Sometimes True:
The sum of a rational number and an irrational number can be rational or irrational depending on the numbers chosen.
For example, 1 + √2 is irrational, but 1/2 + √2/2 is rational.
Always True:
The product of two rational numbers is always rational, as can be shown using the definition of rational numbers.
Always True:
The sum of an irrational number and a rational number is always irrational. This can be shown by contradiction.
Assume that the sum of an irrational number a and a rational number b is rational.
Then (a + b) - b is also rational, which implies that a = (a + b) - b is rational, contradicting the assumption that a is irrational.
Sometimes True:
The product of an irrational number and a rational number can be rational or irrational depending on the numbers chosen.
For example, √2 x 2 is irrational, but √2 x (1/√2) = 1 is rational.
Always True:
The sum of two rational numbers is always rational, as can be shown using the definition of rational numbers.
Thus,

Step-by-step explanation:
C:1
The scale factor of triangles ΔRST and ΔUVW is 1.
Option C is the correct answer.
What is a scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object,
We have,
ΔRST and ΔUVW have the same measure of the corresponding sides.
So,
RS/UV = 8/8 = 1
ST/VW = 7/7 = 1
RT/UW = 7/7 = 1
Thus,
The scale factor of ΔRST and ΔUVW is 1.

Find each value or measure. Assume that segments that appear to be tangent are tangent. Find QS
Answer:
arc QS = 104°
Step-by-step explanation:
arc QTS = 2(128) = 256
arc QS = 360 - 256 = 104°
The measure of arc length QS is 104.
We have,
An inscribed angle is an angle whose vertex is on the circumference of a circle, and its sides are chords of the circle.
From the definition,
Inscribed angle = 1/2 x intercepted arc
Now,
128 = 1/2 x QTS
QTS = 256
Now,
QTS + QS = 360
256 + QS = 360
QS = 360 - 256
QS = 104
Thus,
The measure of QS is 104.

Answer:
solutions: (1, -2), (5, 2)not solutions: (-3, 6), (1, -7)Step-by-step explanation:
The first inequality describes a line with negative slope and y-intercept -4. The solution space is above that line.
The second inequality describes a line with positive slope and y-intercept +1. The solution space is below that line.
Together, the lines make a sort of X on the graph. The resulting solution space will be in the right-side quadrant of that X. Any sufficiently small y-value for a sufficiently large x-value will be a solution. Any point to the left of x=-4 will not be a solution. Values in each category are listed above and shown on the attached graph.

Which unit would you must likely use to measure the capacity of a mug?
A. Teaspoons
B. Quarts
C. Fluid Ounces ?
Answer:
c
Step-by-step explanation:
Fluid Ounces would be likely to use to measure the capacity of a mug.
The unit to measure the volume of a mug is required.
The best suitable unit is fluid ounces.
Let us convert each unit to liters which will help us compare the units.
[tex]1\ \text{teaspoon}=0.00493\ \text{l}[/tex]
[tex]1\ \text{quart}=0.95\ \text{l}[/tex]
[tex]1\ \text{fluid ounce}=0.0296\ \text{l}[/tex]
A teaspoon is to small to measure a mug's volume, while a quart is too large.
So, the best suitable unit is fluid ounces.

1. Divded 35 by 14 and u get 0.4
2
Divided 40 by 0.4 and u get 100
Answer:
16
Step-by-step explanation:
You could solve it two ways:
Cross multiply:
x times 35 = 35x
40 times 14 = 560
35x divided by 35 = x
560 divided by 35 = 16
x = 16
Or:
35 divided by 14 = 2.5
40 divided by 2.5 = 16
x = 16
