Answer:
45°
Step-by-step explanation:
Angle CDE is half of a right angle
1. 90°/2 = 45°
Answers:
- (a) 1/10
- (b) 3/10
- (c) 3/10
- (d) 2/5
===========================================
Explanations:
Part (a)
There is only one disc labeled "3" out of 10 total. So we end up with the probability 1/10.
---------------------
Part (b)
The list of numbers less than 4 are {1,2,3} which are 3 items out of 10 discs. We end up with 3/10.
---------------------
Part (c)
A square number, aka a perfect square, smaller than 10 is the list {1,4,9}
Since 1 = 1^2, 4 = 2^2 and 9 = 3^2
Like part (b), we end up with the same result of 3/10.
---------------------
Part (d)
The list of primes smaller than 10 is {2, 3, 5, 7}. Notice that 1 is not prime.
So we end up with 4/10 = 2/5.
<span>The diagonals of the square are the same length and also perpendicular to each other, being perpendicular means that they meet at a 90 degree angle. The intersection where the two diagonals meet forms 4, 90 degree angles which creates a circle.</span>
The slope-intercept form:
m - slope
b - y-intercept
Answer:
y = -2x + 1
y = 0.6x + 1
y = x + 1
y = 1
y-intercept = 1
You can add the length of the sides to find the perimeter.
8 + 8 + 7 + 12 = 35 inches
