Angles 1 and 2 are complementary. If m<1 = 56°, what is the measure of <2?
Answer:
34°
Step-by-step explanation:
complementary means they equal 90° so you just have to subtract 56 from 90 and then you get your answer.

⅚of the number of pupils in a class is 4 greater than three-quarters of the number in the class .find the number of pupils in the class
Answer:
48 pupils
Step-by-step explanation:
let the number of people in the class be x
⅚ of the number of pupils in a class is expressed as ⅚x
4 greater than three-quarters of the number in the class is expressed as 3/4x+4
Equating both expressions
⅚x = 3/4x + 4
5x/6 - 3x/4 = 4
(10x-9x)/12 = 4
x/12 = 4
x = 4*12
x = 48
Hence the number of pupils in the class is 48 pupils
Write the equation of the line passing through the points (-4, 5) and (4, 1).
9514 1404 393
Answer:
y = -1/2x + 3
Step-by-step explanation:
It can work to start with the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1 -5)/(4 -(-4))(x -(-4)) +5 . . . . . fill in point values
y = -4/8(x +4) +5 . . . . . . . . simplify a bit
y = -1/2x -2 +5 . . . . . .eliminate parentheses

And what does complementary,
supplementary,vertical,
And adjacent angles mean!?!?!
Answer:
angle 6 and 5.
complementary means 2 angles whose sum is 90° and supplementary means 2 angles whose sum is 180°. a way to remember is that is: c(from complementary) is way before s(from supplementary) in the alphabet so you know that complementary has the smaller amount. adjacent angles share the same endpoint of and angle and vertical angles are pairs of the opposite angles made by intersecting lines
What is the circumference of a circle with a radius of 3
inches? Use
3.14
Answer:
C= 18.85 if you want circumference, A= 28.27 if you want area.
Step-by-step explanation:
For circumference, you would want to multiply the radius with pi (pi x 3.14). The formula for it that you could keep in mind is, "C = 2 pi r" For area, the formula of the circle is, "A = pi r^2" or "Area equals pi r squared"
The circumference of a circle with a radius of 3 inches is 18.84 inches.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
We have to find the circumference of a circle with a radius of 3 inches.
The formula for circumference of circle is 2πr
Where r is the radius of the circle.
Given radius is 3 inches
Circumference=2π(3)
=6π
The value of π is 3.14
=6×3.14
=18.84 inches
Hence, the circumference of a circle with a radius of 3 inches is 18.84 inches.

What is the inequality shown?
This type of graph is called a segment.
To write the solution set which represents the graph
of a segment, read the segment from left to right.
If you take a look at the segment shown here, we would start with the endpoint on the left which is a -4, our variable x would be in the middle, and we would finish things off with the endpoint on the right, which is 5.
Since we have an open dot at -4, we use a less than sign between the -4 and the x and since we have a closed dot at 5, we use a less tan or equal to sign between the x and the 5.
It's important to understand that when representing a segment by reading it from left to right, you will only use "less than" or "less than or equal to" between the parts, never "greater than" or "greater than or equal to."
So the solution for this graph is read {x: -4 < x ≤ 5}.
