Sam is 2 yrs old, his mother is 28 yrs old. In how many years will Sam's mother be 3 times as old as him
Answer:
11 years
Step-by-step explanation:
in 11 years
Sam would be 13
and his mother would be 39
39/13 = 3
After 11 years, Sam would be 13 and his mother would be 39.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let the age of Sam's mother = M
Let the age of Sam = S
We are given that Sam is 2 yrs old, his mother is 28 yrs old.
According to the given condition
M = 3S
Then we can see that
39/13 = 3
Hence Sam would be 13 and his mother would be 39 years old.

For a given triangle it is known that cos A =-0.5, where 0°
Based on the information given above, the value of angle(s) A in standard position
could be
A)60°
B)120°
C)210°
D)300°
Answer:
120
Step-by-step explanation:
Here, we want to get the possible value of A
Now, we should understand that the value of an angle in triangle cannot be more than 180
Also, cosine can only be negative in the second and the 3rd quadrant
So,
arc cos (-0.5) = 120 , 300 , 60
But 60 is not correct as it will give a negative value
300 is not correct also as it is more than the angles present in a triangle
Thus, our answer is 120

What is the solution to the system of equations below?
y = negative 3 x minus 9 and y = one-third x minus 39
(9, –36)
(9, 0)
(–9, 18)
(–9, –42)
Answer:
A. (9, –36)
Step-by-step explanation:
The equations are given as:
i) y = -3x - 9
ii) y= 1/3 x - 39
Use equation i) in equation ii)
-3x - 9 = 1/3 x - 39 -------multiply each term by 3 to remove the fraction
-9 x - 27 = x - 117
collect like terms
-9 x- x = -117 + 27
-10 x = -90
10x = 90
x = 90 / 10
x = 9 ------------iii
Use equation iii in i
y = -3x - 9
y = -3 * 9 - 9
y= -27 - 9
y= -36
Hence,
x = 9 , y = -36

Kianna is trying to run a certain number of miles by the end of the month. If Kianna is 75% of the way to achieving her goal and she has already run 30 miles, how many miles is she trying to run by the end of the month?
Answer:
una stoy bien dias
Step-by-step explanation:
The number of miles Kianna trying to run by the end of the month is 40 miles.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Kianna is 75% of the way to achieving her goal and she has already run 30 miles.
Let the total number miles be x.
Now, 75% of x=30
75/100 ×x=30
0.75x=30
x=30/0.75
x=40 miles
Therefore, the number of miles Kianna trying to run by the end of the month is 40 miles.
