Given:
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
To find:
The measure of angle A to the nearest degree.
Solution:
We have,
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
It can be written as
[tex]\angle A=\cos ^{-1}\dfrac{342}{1000}[/tex]
[tex]\angle A=70.00123^\circ[/tex]
[tex]\angle A=70^\circ[/tex]
Therefore, the measure of angle A to the nearest degree is 70 degrees.

A computer costs $800. It loses ¼ of its value every 2 years after it is purchased.
How much will the computer be worth in 6 years?
Answers
The computer will be worth $200.
Step-by-step explanation:
A quarter of $800 is $200, so the computer loses $200 dollars in value every two years. Since 6÷2 is 3, you multiple $200 by 3 to get $600. You then subtract $600 from $800 and get $200.
Answer: The value of the computer at time 0 is $800
The value of the computer at time 1 is $600
The value of the computer at time 2 is $450
The value of the computer at time 3 is $337.50
The value of the computer at time t is (n - 1) x 3/4

Write 2 41/50 as a percent
Answers
Answer:
282%
Step-by-step explanation:
2 and 41/50 is also 82/100 so 282%
The mixed number A = 2 41/50 as a percentage is P = 282 %
Given data ,
Let the percentage value be represented as P
Now , the mixed number is given as A
where the value of A = 2 41/50
On simplifying the number , we get
A = 2 82/100
where the conversion of a fraction to a percent, we divide the numerator by the denominator and multiply by 100.
(141/50) x 100 = 282/1
On simplifying the equation , we get
P = 282%
Therefore, 2 41/50 is equal to 282%
Hence , the percentage value is A = 282 %

Consider all positive integers that are multiples of 10 and are less than or equal to 200. What fraction of those integers are multiples of 15?
A. 1/20
B. 3/20
C. 3/10
D. 2/5
E. 3/4
Answers
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Consider all positive integers that are multiples of 10 and are less than or equal to 200.
Let the number of the positive integer that are multiples of 10 be x. Then the equation will be
10x ≤ 200
Then the value of the x will be
x ≤ 20
The set of numbers is given below.
Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}
The set which is divisible by 15 will be
Set = 6 {30, 6,0 90, 120, 150, 180}
Then the fraction of those integers are multiples of 15 will be
⇒ 6 / 20
⇒ 3/10
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

Step 1: Simplify both sides of the equation.
x2−8x+15=35
Step 2: Subtract 35 from both sides.
x2−8x+15−35=35−35
x2−8x−20=0

All I know is that you have to subtract 1575 from 5,000 and then you get 3,435 dollars left and you divide that by 26 people and you get 131.731 but of course you can't have a half of person so it stays at 131.
