Answer:
see explanation
Step-by-step explanation:
A rational number can be expressed in the form
[tex]\frac{a}{b}[/tex] where a and b are integers
Given
- 27 = [tex]\frac{-27}{1}[/tex] ← in rational form
Thus - 27 is a rational number
if 3 point A,B, and C are collinear and B is between A and C then?
Step-by-step explanation:
Collinear points: Three points A, B and C are said to be collinear if they lie on the same straight line. There points A, B and C will be collinear if AB + BC = AC as is clear from the adjoining figure.
Gemma has 24 balls out of 24 balls 12 are yellow for pink and the rest are red what is the ratio of the number of red balls to the number of balls that are either yellow or pink
Answer:
12:12
Step-by-step explanation: 24-12 = 12 red balls therefore the ratio would be 12:12.

Answer:
The lengths of the sides are 30 ft, 60 ft, 15 ft, 45 ft
Step-by-step explanation:
The perimeter is 150 ft, the length of the fence.
We add the lengths of the sides and set equal to the perimeter. Then we solve for x. Once we know x, we find the length of each side.
x + 2x + 0.5x + 45 = 150
3.5x = 105
x = 105/3.5
x = 30
Lengths of sides:
x = 30
2x = 2(30) = 60
0.5x = 0.5(30) = 15
45
Answer: The lengths of the sides are 30 ft, 60 ft, 15 ft, 45 ft

A 50 litre solution of acid and water contains 10 litres of acid. How much water must be added to make the solution 8 % acidic. Will mark brainest to whoever answers.
Answer:
Your welcome!Step-by-step explanation:
Acid present in the solution = 10 L
Required volume concentration of acid = 8/100
Let x amount of water be added to achieve the required %.
In the new solution, proportion of acid= 10/(50+x)
Therefore,
10/(50+x) = 8/100
x=75
Ans: 75 L of water must be added to the solution

Which expression gives the distance between the points (3, -8) and (3, -19)? *
1 point
Captionless Image
|3 - 3|
|-19 - (-8)|
|3 + (-19)|
|3 - (-8)|
| 3 + (-19) |
Answer:
| - 19 - (- 8) |
Step-by-step explanation:
Given that the 2 points have the same x- coordinate, then the distance between the 2 points is the difference in the y- coordinates, that is
distance = | - 19 - (- 8) | = | - 19 + 8 | = | - 11 | = 11
Or
distance = | - 8 - (- 19) | = | - 8 + 19 | = | 11 | = 11
is 7/8 natural, whole, integer, rational, irrational
– 5 | 3 z + 8| –5 = -20
I'm assuming you want to solve for z :)
By simplifying both sides of the equation, then isolating the variable.
Exact form:
z= -5/3 , - 11/3
Mixed number form:
z= −1 2/3 , −3 2/3
Answer:
There are two solutions, -5/3 and -11/3
Step-by-step explanation:
Move -5 to the right side and add:
-5 | 3x + 8 | = -15
Get rid of the absolute-value bars by splitting them into negative and positive cases.
Solve negative case
-5 ( 3z + 8 ) = -15
Distribute or Multiply:
-15z - 40 = -15
Rearrange and Add:
-15z = 55
Divide both sides by 15:
-z= 11/3
Multiply both sides by -1:
z= -11/3
Solve negative case
5 ( 3z + 8 ) = -15
Distribute or Multiply:
15z + 40 = 15
Rearrange and Add:
15z = -25
Divide both sides by 15:
z = -(5/3)
Answer
z=-11/3
z=-5/3

What is the range of the function graphed below?
Answer: C -3< y ≤ 3
Step-by-step explanation:
Starting from the lowest point of the y coordinate to the highest point of the y coordinate. The lowest point is -3 and highest point is 3.At the y coordinate -3 there is an open circle which means we are excluding it and at the highest point 3 there is a closed circle so we will have to include that.

Which fraction is equivalent to that number? HELP NEEDED ASAP
Answer:
2/3
Step-by-step explanation:
Let n = the repeating, non-terminating number 0.666...
We now have n = 0.666666...
We want the number n in the form of a fraction.
Since only 1 digit repeats, the 6, use a 1 followed by 1 zero, which means the number 10. Now multiply both sides by 10 and write the original equation below it.
10n = 6.666666...
n = 0.666666...
Subtract the bottom equation from the top equation.
9n = 6
n = 6/9
n = 2/3

f(x)=-4x-6 and g(x)=3x+5. Find (f o g)(-3) plzzzzzzzzzzz helpppppppp
Answer:
(f o g)(-3) = 10Step-by-step explanation:
f(x) = - 4x - 6
g(x)=3x+5
To find (f o g)(-3) we must first find
(f o g)(x)
To find (f o g)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)
That's
(f o g)(x) = - 4( 3x + 5) - 6
= - 12x - 20 - 6
(f o g)(x)= - 12x - 26
Now to find (f o g)(-3) substitute the value of x that's - 3 into (f o g)(x) and solve
We have
(f o g)(-3) = - 12(-3) - 26
= 36 - 26
We have the final answer as
(f o g)(-3) = 10

Step-by-step explanation:
How would you express b⃗ using unit vectors? express your answers in terms of the unit vectors x^ and y^. use the unit vector button under the templates menu in the answer box to create unit vectors?
Answer:
This question seems to be incomplete, so i will answer it in a general way.
If we have a vector;
b = (b1, b2)
where b1 and b2 are the x-component and the y-component (respectively) of the vector b, then we can write the vector as:
b = (b1, b2) = b1*x^ + b2*y^
Where x^ = (1, 0) and y^ = (0, 1)
Are the unit vectors.

PLEASE HELP explain how you can prove two circles are similiar
Answer:
By Looking at the shapes and sizes
Step-by-step explanation:
If you can try and look at the shape and size of it, if you can draw it, draw it on a piece of paper, trace them both, but in the same spot, you didn't specificize, if it was a sphere or just a regular circle or not, so thats all i can tell you.
