Answer:
The correct option is;
3 + (-9) = -6, because -6 is 9 units to the left of 3
Step-by-step explanation:
The given information are;
Kelvin's score after the first round is shown at point K on the number line
The range of numbers on the number line = -10 to +10
The position of point K after the first round = +3
The number of points Kevin lost in the second round = 9 points
Therefore, Kevin's cumulative score = +3 - 9 = -6
Therefore, the expression that shows how many total points he has at the end is of round 2 = 3 + (-9) = -6, because -6 is 9 units to the left of 3.
Answer:
Step-by-step explanation:
Ratios are no different from fractions. They are "comparisons" of 2 or more things. Instead of fraction bars, they use colons to separate 2 different things.
For example:
Now, let's do an example problem.
Ex: find the ratio of 5 cats to every dog.
We are comparing 5 cats to every 1 dog, so the ratio is:
Don't make thing more complicated to yourself, and don't overthink it. They are exactly like fractions. So treat them as such!
Answer:
r=8
t=4√29
Step-by-step explanation:
By the altitude leg theorem:
This implies that:
We simplify to obtain:
By the Pythagoras theorem:
Answer:
45.
Step-by-step explanation:
Each exterior angle = 180 - 172 = 8 degrees.
Since the total of the exterior angles = 360 the number of sides =
360 / 8
= 45 sides.
NOTE: the total of exterior angles of all polygons = 360 degrees.
Answer:
33
Step-by-step explanation:
Because 66 is 200% just divide that by 2. Then 33 would be 100%
