Answer:
The length of the remaining wire is 53.8 centimeters
Step-by-step explanation:
Let us solve the question
∵ Cory has 66.92 centimeters of wire
∵ He uses 2 pieces of the wire, each piece he uses is 6.58 cm long
→ Find the length of the two pieces he uses
∵ He uses = 2 × 6.58
∴ He uses = 13.16 cm
∴ The length of wire he uses is 13.16 cm
→ The length of the remaining = the total length - the length he uses
∵ The length of the remaining = 66.92 - 13.16
∴ The length of the remaining = 53.76 cm
→ Round it to the nearest tenth of a centimeter
∴ The length of the remaining = 53.8 centimeters
∴ The length of the remaining wire is 53.8 centimeters
Answer:
30.2
Step-by-step explanation:
cos(58) = 16/BC
BC = 16/cos(58) = 30.2
a. The difference between two outputs that are 1 unit apart.
You need to Use y2 - y1 / x2 - x1 to find the difference
I will choose x2 as 1 and x1 as 0
(29 - 21) / (1 - 0)
8/1 so The difference is 8 per 1 unit.
b. Use the same formula
I will choose -3 as x2 and -5 as x1
(5 - (-11)) / (-3 - (-5))
(5 + 11) / (-3 + 5)
16 / 2 so the difference is 16 per 2 units.
c. I will choose 2 as x2 and -1 as x1
(45 - 21) / (2 - (-1))
24/3 so the difference is 24 per 3 units.
d. The ratios of the differences to the input intervals reduced all equal each-other, which is 8 per 1 unit.
Answer:
The
90
adult tickets sold were
45
%
of the
200
tickets sold to the concert.
Explanation:
Since
90
tickets out of
200
were adult tickets, the percentage (represented as
x
) can be calculated by this equation:
200
