Answer:
The pet sitter babysat his dog for 3 hours.
Step-by-step explanation:
You know that a pet sitter charges $ 20 for supplies and $ 10 per hour of service, represented by the equation C = 10*n + 20, which describes the total cost she would charge for n hours of service.
The pet sitter charges a customer $ 50 for his service, so C has a value of $ 50.
Replacing:
50=10*n+20
Solving:
50 - 20= 10*n +20 -20
30= 10*n
30÷10= n
3= n
<u><em>The pet sitter babysat his dog for 3 hours.</em></u>
Answer:
The answer is -1
Step-by-step explanation:
f(x) = 2x³ + x² - 3x - 1
f(1) = 2(1)³ + (1)² - 3(1) - 1
f(1)= 2 + 1 - 3 - 1
f(1)=3-3-1
f(1)=0-1
f(1)= -1
Thus the answer is -1 ....

Answer:

Step-by-step explanation:
The given equation is:

We have to find the logarithmic equation with same solution as the given equation.
If we take the log of both sides, we can get a logarithmic equation. Since the log operation is applied to both sides the solution of the equation will stay the same.
Taking the logarithm to the base 3 of both sides, we get:

Answer:
The smallest angle of the triangle is 
Step-by-step explanation:
we know that
If the sides of a triangle are
,
, and
, then
we have a right triangle
because, applying the Pythagoras theorem

-------> is true
Remember that the measure of the smallest angle of triangle is the opposite angle to the smallest side
so
Let
A-------> the measure of the smallest angle


Round to the nearest degree
