Answer:
The answer should be 5:12.
Step-by-step explanation:
Since the question asks what's the ratio of cheerleaders to football players, the ratio before simplifying would be 20:48.
So, just find the greatest common divisor of 20 and 48, which would be 4.
20/4 = 5
48/4 = 12
Therefore, the answer to this question and the ratio of cheerleaders to football players is 5:12.
Answer:
4.75
Step-by-step explanation:
19/2 = 9.5
9.5/2 = 4.75
4.75
Answer:
C' = (2, 1)
Step-by-step explanation:
The co-ordinates of C from the graph is: C(6, 3).
When a co-ordinate is dilated by a factor, say 'a' then each term in the co-ordinate is dilated by 'a'.
Therefore, here, we will have: 
(6, 3)
= (2, 1)
Call this C'. Therefore, the co-ordinate of C' = (2, 1).
Hence, the answer.
Answer:
85 + z <= x <= 255 + z
Step-by-step explanation:
An inequality system will be given by a lower limit and an upper limit, therefore it is only necessary to raise an equation for each case, h being the hours worked and z the extra money you can earn by delivering the pizzas:
For the lower limit:
8.5 * h + z, knowing that in this case it is 10 hours.
85 + z would be the lower limit value
For the upper limit:
8.5 * h + z, knowing that in this case it is 30 hours.
225 + z would be the upper limit value
Therefore the inequality system would be as follows, let x be the money earned:
85 + z <= x <= 255 + z
Which means that the money earned will be determined by the previous inequality.
Answer:
a=42°
b=138°
Step-by-step explanation:
the sum of angles on a triangle is 180°
so
18+120+a=180
138+a=180
a=180-138
a=42
a+b=180 because a ans b are linear pair of angles.
Definiton:A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
a=42 from before
it means that b=180-42=138
