Which of the following is NOT a classification for the number 8? A. irrational
B. real
C. integer
D. whole
Answers
The number ' 8 ' is real, whole, and an integer.
It's also rational, so 'A' doesn't belong.

We take the information from the text given, to find the number of pieces.
We have that:
- One piece is 1/4 of the entire pie.
- The other n pieces are each 1/8 of the pie.
Doing this, we get that the number of pieces is 7 pieces, option D.
Sum:
The entire fraction pie is:
The entire fraction is 1, so:
How many pieces of pie are there?
We have to solve the equation for n, so:
6 pieces at 1/8, and the 7th at 1/4. Thus, there are 7 pieces, and the correct answer is given by option D.
A similar question is given at brainly.com/question/21359576
Answer:
D
Step-by-step explanation:
1/4 of the pie is one piece. This leaves 3/4 of the pie. Each remaining piece is 1/2 of the larger quarter piece. The smaller pieces are 1/8 of the pie.
The fraction 3/4 = 6/8.
This makes 6 smaller pieces. each of 3 quarters is split in half.
6 + 1 = 7.
7 pieces in all.
If you do not like arithmetic, draw a picture. Split the pie in quarters. Cut all except for one of them in half. This gives 7 pieces.
What is m∠B?
_________ °
Answers
Answer:
Measure of ∠B is 60°
Step-by-step explanation:
Given triangle ABC is similar to triangle QRS.
m∠A = 45° and m∠S = 75°
we have to find the measure of ∠B.
As triangles are similar then corresponding angles are congruent.
⇒ ∠A≅∠Q, ∠B≅∠R, ∠C≅∠S
hence, m∠C=m∠S=75°
By angle sum property
m∠A+m∠B+m∠C=180°
⇒ 45°+m∠B+75°=180°
⇒ m∠B+120°=180°
⇒ m∠B=60°
hence, measure of ∠B is 60°
A fence is placed along the entire perimeter of the triangular garden. The roll of fencing is 40 ft long.
Part B: Write a simplified expression to show the amount of fencing, in feet, which is left from the roll of fencing.
Answers
p = x + (2x+5) + (2x+5)
or
p = x + 2(2x+5)
This is actually an equation so the expression to represent perimeter would simply be...
x + 2(2x+5)
B: Since we know the equation for the perimeter and we know that we have 40 feet of fencing, then the equation to find the left over fencing would just be the length of fencing minus the perimeter...
40 - x + 2(2x+5) = the leftover amount of fencing
so the expression is...
40 - x + 2(2x+5)

Answer:
13. The slope for a line that is perpendicular to the line y=4x+8 is -1/4
14. The slope for a line that is perpendicular to the line x=-6 is 0
15. The equation for a line that is perpendicular to the line 8x-4y=12 and passes through the origin is y = - (1/2) x
16. The equation for a line that is perpendicular to the line y=-(1/3)x and passes through the point (0,-10) is y=3x-10
Step-by-step explanation:
13. What is the slope for a line that is perpendicular to the line y=4x+8?
y=mx+b
Comparing with the form slope-intercept, the slope of the given line is the coefficient of x, then the slope of the given line is 4.
A line perpendicular to y=4x+8 must have a slope opposite and inverse, then:
Slope of the perpendicular = - 1/4
14. What is the slope for a line that is perpendicular to the line x=-6?
The line x=-6 is a vertical line. A line perpendicular to the line x=-6 must be a horizontal line (Angle=0°), then:
Slope of the perpendicular = tan Angle = tan 0° = 0
15. Write the equation for a line that is perpendicular to the line 8x-4y=12 and passes through the origin.
8x-4y=12
Isolating y: Subtracting 8x both sides of the equation:
8x-4y-8x=12-8x
-4y=-8x+12
Dividing all the terms by -4:
-4y/(-4)= -8x/(-4)+12/(-4)
y=2x-3
The slope of the given line is 2
The slope of the perpendicular is m=-1/2 (opposite and inverse to the slope of the given line)
The perpendicular passes through the origin:
P1=(0,0)=(x1,y1)→x1=0, y1=0
Using the equation point - slope:
y-y1=m(x-x1)
Replacing the known values:
y-0=(-1/2)(x-0)
y=(-1/2)x
16. Write an equation for a line that is perpendicular to the line y=-(1/3)x and passes through the point (0,-10).
The slope of the given line is -(1/3)
The slope of the perpendicular is m=3/1→m=3 (opposite and inverse to the slope of the given line)
The perpendicular passes through the point:
P1=(0,-10)=(x1,y1)→x1=0, y1=-10
Using the equation point - slope:
y-y1=m(x-x1)
Replacing the known values:
y-(-10)=3(x-0)
y+10=3x
Isolating y: Subtracting 10 both sides of the equation:
y+10-10=3x-10
y=3x-10
