Total cost=$142
cost of parts=$62
cost paid for labour=$142-$62=$80
According to question,
》cost of labour per hr=$32
which can be written as,
》cost of labour/time=$32
Use cross multiplication,
》time=cost of labour/32
Since cost of labour is 80,
Time=80/32
=2.5hrs

The expression that can be used to represent x is not shown.
x is the price of the shoes
5% commission on every pair of shoes sold. $1.00 is the value of the commission received.
$1/5% = 1 / 0.05 = 20
The price of the shoes is 20.
Answer: 9cm
Step-by-step explanation:
The circumference of a circle is given as: = 2πr
where,
π = 3.142
r = radius = unknown
Since circumference = 56.52cm, we'll slot it into the formula which will be:
Circumference = 2πr
2πr = 56.52
2 × 3.142 × r = 56.52
6.284r = 56.52
r = 56.52 / 6.284
r = 8.99
r = 9cm approximately
Answer:
A
Step-by-step explanation:
Two facts need to guide your answer.
One
The highest power is odd: you know this because an even power would start on the left come down do it's squiggles if had any and wind up on the right going up.
This graph comes down on the left does it's squiggles and then goes further down on the right. That's the behavior of something whose highest power is odd.
Two
The leading coefficient, the number in front of the highest power must be minus. If it was positive as in y = x^3 the graph would be the mirror image of what it is.
Argument
B and D cannot be true. The highest power is even.
C is false because the leading coefficient is + 1.
So that leave A which is the answer.
The graph is included with this answer
