Step-by-step explanation:
anton defines an acute angle as an angle that is not obtuse. is antons definition valid?
Answer:
No
Step-by-step explanation:
Acute angles are angles that measure less than 90 degrees. Obtuse angles are angles that measure more than 90 degrees. However, there are other types of angles. Take a right angle for example. It measures exactly 90 degrees, therefore it is neither obtuse or acute. So, Anton's definition cannot be valid - there are still other angles that are not obtuse that don't qualify as acute, either.

Answer:
y=1/4x+2.75
Step-by-step explanation:
two coordinates are: (5,4) and (-3,2)
the linear function is y=mx+b
m=slope
b=y-intercept
first, find the slope
the formula to find the slope is y2-y1/x2-x1
2-4/-3-5=
-2/-8=
1/4
Now you know 1/4 is the slope. Plug that into the function
y=1/4x+b
Now find the y-intercept
to do that, take one of your coordinates and plug the x and y values into the function.
I will use (-3,2)
2=1/4(-3)+b
2=-3/4+b
11/4=b
(or 2.75 decimal form)
Plug the y-intercept into the function and you're done
y=1/4x+2.75
Find the sum. In your final answer, include your calculations.

elie is now 4 times as old as her son. in 5 years time shes going to be 3 times as old as her son. how old is ellies son now?
Answer:
Her son is 10 years old.
Step-by-step explanation:
Let son be x
Ellie is 4x
In 5 years time: Her son = x + 5
Ellie = 4x + 5
Given that she will then be 3 times as old as her son: 4x + 5 = 3(x + 5)
Solve x: 4x + 5 = 3(x + 5) ,4x + 5 = 3x + 15
x = 10

Cassandra sells merchandise at the local golf course. 35 golf shirts and 60 golf shorts cost $3,017.50 and 68 golf shirts and 180 golf shorts cost 8,149.09.
Answer:
Al bought a sound system that lost a total of $650.00,
and he also bought some CD’s at $9.99 each. The total
that Al spent was $719.93. How many CD’s did Al buy?
[Ignore sales tax.]
1. 650.00 + 9.99n = 719.93
2. 650.00 − 9.99n = 719.93
3. 650.00 × 9.99n = 719.93

The required cost of each golf shirt and golf shorts is $34.7 and 26.7 respectively.
Given that,
Cassandra sells merchandise at the local golf course. 35 golf shirts and 60 golf shorts cost $3,017.50 and 68 golf shirts and 180 golf shorts cost 8,149.09. To determine the cost of each golf shirt and golf shorts.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
let the cost of each golf shirt and golf short be x and y respectively
Accoding to the question,
35x + 60y = 3017.50 - - - - - - - (1)
68x + 180y = 8149.90 - - - - - - (2)
From equation 1
x = [3017.50 - 60y] / 35 - - - - -(3)
put x in equation 2
we get
y = $34.7
now put this y in equation 3
x = $26.7
Thus, the required cost of each golf shirt and golf shorts is $34.7 and 26.7 respectively.

In one week, a mill worker worked 12,11,13,12,15,16, and 14 hours. Identify the median number of hours worked
Answer: 13
Step-by-step explanation:
First, we have to arrange the numbers in either ascending or descending order.
12,11,13,12,15,16, and 14 hours will then be: 11, 12, 12, 13, 14, 15 and 16.
The median will be gotten using the formula: = (n + 1) / 2
Since there are 7 numbers this will be:
= (n + 1) / 2
= (7 + 1) / 2
= 8/2
= 4th number
Since 13 is the 4th number, it's the median
