Which statement is true? Integers are always whole numbers or all whole numbers are rational or integers include all rational members or rational numbers do not include integers.
Let's go through each statement to see if it is true or false.
=====================================
Integers are always whole numbers
This is true. Integers are numbers that don't have any fractional or decimal portion
=====================================
All whole numbers are rational
This is also true. Let's say we had the whole number 7. We can write it as 7/1 which is rational. A rational number is any number that can be written as a fraction of two integers. So this means any whole number can be converted to a rational number format.
=====================================
Integers include all rational members
This is false. It is true that all integers are rational, but there is more to the story than just integers when it comes to listing all rational numbers.
For instance, the number 1/2 is rational, but it is not an integer.
=====================================
Rational numbers do not include integers.
This is false. As stated earlier, any integer can be placed over 1 to form a rational number. So the rational numbers do include integers, among non-whole number fractions as well.

15 - 112.5 = 7.5
15 : 112.5 = 75
112.5 : 15 = 7.5
112.5 : 15 = 75
What’s the answer
Answer:
112.5:15=7.5
Step-by-step explanation:
112.5:15
=112.5÷15
=7.5
The equation "112.5 : 15 = 7.5" is true.
Proceed option 1:
"15 - 112.5 = 7.5":
This equation is not correct because 15 - 112.5 does not equal 7.5.
Proceed option 2:
"15 : 112.5 = 75":
This equation is not correct because when we divide 15 by 112.5, we get a decimal answer of 0.1333, not 75.
Proceed option 3:
"112.5 : 15 = 7.5": This equation is correct.
When we divide 112.5 by 15, we get an answer of 7.5.
Proceed option 4:
"112.5 : 15 = 75": This equation is not correct because when we divide 112.5 by 15, we get an answer of 7.5, not 75.
Hence equation "112.5 : 15 = 7.5" is correct.

Li uses 8.4 grams of sugar every day in her tea. Sue uses 12.6 grams of sugar every day in her coffee. If Li’s sugar canister contains 128 grams of sugar and Sue’s canister contains 191 grams, in how many days will Li and Sue have the same amount of sugar in their canisters?
Answer:
They will have the same amount of sugar in their canisters in 15 days
Step-by-step explanation:
Here in this question, we are concerned with knowing the number of days in which the amount of sugar in both canisters will be the same.
Since we do not know the number of days it will
take, we have to represent it using a variable.
Let the number of days be x days
Now, we are told Li uses 8.4 g per day.
So in x days, the amount user will be 8.4 * x = 8.4x g
Thus, the amount of sugar remaining in her canister after x days will be 128 - 8.4x
For Sue, she uses 12.6 grams each day. So in x days, the amount of sugar used will be 12.6 * x = 12.6x g
So the amount of sugar left in her canister will be 191-12.6x
Since on the xth day , the amount of sugar remaining is same, we can equate the amount of sugar remaining in both canisters. That would be;
128-8.4x =191-12.6x
Collect like terms;
12.6x-8.4x = 191-128
4.2x = 63
x = 63/4.2
x = 15 days

Answer:
(i) F = 25 N
(ii) F = 35.36 N
(iii) F = 43.3 N
Step-by-step explanation:
We note that the component of force acting along the incline surface is given by the relation
Force, acting parallel to the incline plane, [tex]F_p[/tex] = M×g×sin(θ)
Given that the weight of the body is given as 50 N, we have;
M×g = 50 N
Therefore we have;
(i) For the plane with angle of elevation = 30°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(30°) = 25 N
The force [tex]F_p[/tex] = F = 25 N
F = 25 N
(ii) For the plane with angle of elevation = 45°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(45°) = 50 × (√2)/2 = 25·√2 N
[tex]F_p[/tex] = F = 25×√2 N = 35.36 N
F = 35.36 N
(iii) For the plane with angle of elevation = 60°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(60°) = 50 × (√3)/2 = 25·√3 N
[tex]F_p[/tex] = F = 25×√3 N = 43.3 N
F = 43.3 N.
somebody plz come in clutch
Answer:
B. x = 7/2 or x=-1/3
Step-by-step explanation:
You know both angles 6x² and 19x+7 have to be the same, so you can solve
6x² = 19x+7
6x² - 19x - 7 = 0
apply the quadratic formula and find
x = -1/3 or x = 7/2
now think carefully if the negative x is a realistic solution. It would lead to the angles being (2/3)°. This is not what the picture suggests, but it is also not wrong, so answer B seems the best.

Answer:
D. 22.5
Step-by-step explanation:
By the property of intersecting tangent and secant outside of the circle, we have:
x° = 1/2[(4x+5)° - 50°]
2x° = [(4x+5)° - 50°]
2x° = (4x-45)°
2x = 4x - 45
45 = 4x - 2x
45 = 2x
x = 45/2
x = 22.5
The measure of the variable x will be 22.5°. Then the correct option is D.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
We know that half of the difference between the angle (4x + 5)° and 50° will be equal to x°. Then the equation will be
x = [4x + 5 - 50] / 2
Simplify the equation, then we have
2x = 4x - 45
2x = 45
x = 22.5°
The measure of the variable x will be 22.5°.
Then the correct option is D.

Step-by-step explanation:
Given
[tex]y = 4x + 1[/tex]
[tex]y = 4x + 10[/tex]
Required
Show that these two lines have no point of intersection
The general equation of a line is
[tex]y = mx + b[/tex]

What is the y-intercept of the polynomial f(x)f(x) f(x) defined below? Write the y-value only. f(x)=−4x2+x5+10x3+5x+8x4f(x)=-4x^2+x^5+10x^3+5x+8x^4 f(x)=−4x 2 +x 5 +10x 3 +5x+8x 4
Answer:
y = 0
Step-by-step explanation:
Given
f(x) = 4x² +x⁵ +10x³ +5x+8x⁴
Required
Determine the y intercept
The y intercept of a function is a point where x = 0
So, we have to substitute 0 for x in the above function
f(x) = 4x² +x⁵ +10x³ +5x+8x⁴ becomes
f(0) = 4(0)² +(0)⁵ +10(0)³ +5(0)+8(0)⁴
f(0) = 4 * 0 + 0 + 10 * 0 + 5 * 0 + 8 * 0
f(0) = 0 + 0 + 0 + 0 + 0
f(0) = 0
Substitute y for f(0)
y = 0
Hence, the y intercept is 0

289 and y more is 206
Answer:
Equation translates to 289 + y = 206
it solves to y = -83
====================================================
Explanation:
The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.
Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206
This is the same as saying y+289 = 206
To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides
y+289 = 206
y+289-289 = 206-289
y = -83
So we are adding -83 to 289 to get 206

Explanation:
The chords intersect to form the angle 73 degrees. The chords also form the arcs of 96 and x. Averaging the arc measures will result in the internal angle 73
---------
(x+96)/2 = 73
x+96 = 2*73 ... multiply both sides by 2
x+96 = 146
x = 146-96 ... subtract 96 from both sides
x = 50

Imagine that you stop at a nearby coffee chain and purchase a $5 coffee every morning on your way to work. You do this 5 days a week for 50 weeks out of the year. While it may seem like a small expense each day, this habit can add up and affect your personal finances. How much would this habit cost you over the next five years
Answer:
$6250
Step-by-step explanation:
Hello!
First, we find out how much you spend a week.
Since you buy a $5 coffee 5 days a week we multiply the price for a coffee by 5.
5 * 5 = 25.
Next, we find out how much you spend a year.
Since you do it 50 weeks a year we multiply the amount you spend a week by 50
25 * 50 = 1250
Then, we find out how much you spend in 5 years.
We multiply the cost a year by the amount of years
1250 * 5 = 6250
The answer is $6250

Given xy = 4 and x2 + y2 = a, which expression is equal to (x + y)2?
a + 6
a + 8
a + 4
Answer:
a + 8
Step-by-step explanation:
Note that
(x + y)² = x² + 2xy + y²
= x² + y² + 2xy
= a + 2(4) = a + 8
Here, we are required to determine an expression equal to (x + y)²
The correct answer is therefore (a + 8)
First, x² + y² = a can be rewritten completing the square method as;
(x+y) (x+y) = a + 2xy
when we expand the expression above; we have;
x² + 2xy + y² = a + 2xy
since, 2xy is present on both sides of the equation;
we still get the expression; x² + y² = a
Therefore, (x+y)² = a + 2xy
we can then substitute the value 4 for xy in the equation above;
Thus, since xy = 4, therefore 2xy = 8
Consequently, (x+y)² = a + 8
The correct answer is therefore (a + 8)
