Answer:
9
Step-by-step explanation:
the triangle is right angle.
at right angle it makes 90°. therefore;
(3d+1)°+(6d+8)°=90°
3d+1°+6d+8°=90°
9d+9°=90°.
9d=90°-9°
9d=81°
d=81/9
d=9°
Answer: thus Luis pays 3/5 of the original price.

Answer:
209
Step-by-step explanation:
You would first create an explicit formula for the provided sequence.
The basic explicit formula for arithmetic sequences is
, where an is the number of the term, d is the number you are adding or subtracting by, n the location of the term, and a1 is the first number.
We would then substitute the values given into the formula.
We are trying to solve the value of the 52nd term. This makes n = 52. The first number of the sequence is 5, so a1 is 5. Finally, d is 4 because we are adding 4 to each number in the sequence.
Therefore, our resulting equation would be
, which equals 209.
Answer:
It is a random sample
The second sample is more representative of a population
The second sample gives better representation because it is larger
Step-by-step explanation:
According to the given statement we have been given two statements and we have to determine how often people in a community listen to the local radio station each month.
If you notice the second sample it is a random sample because people who visited the store had equal probability of being chosen.
The second sample is more representative of a population because it is a larger sample than the first sample and the sample are taken from the only local grocery store.
The second sample gives better representation because it is larger ...
Step-by-step explanation:
Perimeter is add all the sides together.
So 7.2+3.7+13
So P=23.9 inches
