Answer:
98
Step-by-step explanation:
x(o) + 1(o) = 180(o)
∠2° = ∠x°
∠1° = ∠3°
4miles ..............56 minutes
42miles .............x
x= (42*56)/4
x= 2352/4
x= 588
Answer:
You use PEMDAS.
Step-by-step explanation:
If you dont know what that is, its the process used for long multistep equations like that : Parenthesis, Exponents, Multiplication, Division, Addition, then Subtraction. You solve all of those in order (if they are included in the problem). So for this you would solve one side of the inequality sign first using this order, then the other side and BAM! you've solved this problem.
Let
x--------->number of products
y1--------> <span>the cost of producing a product
y2------> </span><span>the cost of sell a product
</span><span>
we know that
y1=120,000+20x-------> equation 1
y2=50x------> equation 2
equate equation 1 and equation 2
120,000+20x=50x
50x-20x=120,000
30x=120,000
x=4000
the answer is
4000 pieces</span>
Answer:
t2 = 2.8 hours
Step-by-step explanation:
The distance is the same for each velocity.
Formula
d1 = d2
d = r*t
Givens
r1 = 140 miles / hour
t1 = 3.2 hours
r2 = 160 miles / hour
t2 = ?
Equation
r1*t1 = r2 * t2
Solution
140 * 3.2 = 160 * t2
448 = 160* t2
448 / 160 = t2
t2 = 2.8 hours
