Answer:
scalene
Step-by-step explanation:
step 1
Find the value of y
we know that
The sum of the interior angles in a triangle must be equal to 180 degrees
In this problem
m∠A+m∠B+m∠C=180°
substitute the given values
Solve for y
step 2
<em>Find the measure of angle B</em>
m∠B=(y+40)°
substitute the value of y
m∠B=(15+40)=55°
step 3
<em>Find the measure of angle C</em>
m∠C=(3y-10)°
substitute the value of y
m∠C=(3(15)-10)=35°
The three interior angles are different
so
The three sides of the ABC triangle will also be different
therefore
The right triangle ABC is scalene
Answer:
and
Step-by-step explanation:
First make all the fractions into improper fractions
After doing that put them back into the problems
Problem 1)
÷ 
, plug in the improper fractions
÷ 
to divide, you need to flip the second fraction and multiply
· 
= 
then reduce
Problem 2)
÷ 
Plug in improper fraction
÷
Then flip second fraction and multiply
· 
Multiply
Reduce, or make it a mixed number
Answer:
f(x)=nx
or
f(x)=9.50x
Step-by-step explanation:
Let x be the amount of hours and n be the hourly rate (9.50).
or if you prefer to use 9.50 instead of n, the function would be:
Answer:
-25/12
Step-by-step explanation:
first, you need a common denominator. in this case, it's 12.
-1/3=-4/12
-7/4=-21/12
and then you add
-4+-21=-25
so -25/12 is your answer
The answer would be 24 because 24-4 is 20
