Answer:
A-75 and B-25
Step-by-step explanation:
Firstly, divide the 200 students by the amount of sections (8) and that gives you 25 a section. Since year 7 has 3 sections and year 9 has 1, 3(25)=75 and 25(1)=25.
Center- A
Radius-D
Circumference-C
Diameter-B
Solution:
Vertical angles are a pair of opposite angles formed by intersecting lines. re vertical angles. Vertical angles are always congruent.
These two angles (140° and 40°) are Supplementary Angles because they add up to 180°:
Notice that together they make a straight angle.
Hence,
From the image
The following pairs form vertical angles
Hence,
One pair of the vertical angles is ∠1 and ∠3
Part B:
Two angles are said to be supplementary when they ad together to give 180°
Hence,
From the image,
The following pairs are supplementary angles
Hence,
One pair of supplementary angles is ∠5 and ∠6
.57 because 57/100 is like 57% and pretend that the percent is like a magnet and pulls the decimal two spaces to the right
So firstly, you want to multiply x on each side of the equation:
Next, subtract 1 on each side:
Next, we will be using the quadratic formula, which is , with a = x^2 coefficient, b = x coefficient, and c = constant. Our equation will look like this:
Firstly, solve the exponents and multiplications:
Next, do the addition, and your exact solutions are: and
