We know that all black beards cost the same money
And all red beards cost $25
And B represents number of black beards
And R represents number of red beards
We have been given the inequality 20B+25R > 350 to show the target for this month.
The above inequality shows that Merlin needs to make more than 350, hence he made 350 last month
Further, it shows that B has been multiplied by 20, hence the black beard's cost was 20
Answer:
C) 1/6y+1/6(y+12)-2
Step-by-step explanation:
Answer:
Volume = 2520 cm^3.
Step-by-step explanation:
The volume of a pyramid = 1/3 * area of the base * height.
The base of this pyramid is a triangle and its area
= 1/2 * 18 * 24 cm^2 so the volume of the pyramid is:
1/3 * 1/2 * 18 * 24 * 35
= 2520 cm^3.
Answer:

Step-by-step explanation:
To verify cos²A + sin²A = 1 with A = 90° , then
cos²90° + sin²90°
= (0)² + (1)²
= 0 + 1
= 1
Answer:
they will be the same at 11 months
Step-by-step explanation:
the equations for this are
y = 40+55x
and
y = 165+30x
where x is the number of months
if you plug this into your graphic calc you see they are equal at 11 therefore, 11 months
