Answer: 0.50, which is choice b
Explanation:
The interval 
covers 5-1 = 4 units in the horizontal direction.
This is out of 8 units that span from x = 0 to x = 8 (we could say 8-0 = 8).
So we get the final result of 4/8 = 0.50
In other words, the interval from x = 1 to x = 5 covers exactly half of the interval from x = 0 to x = 8.
Answer: a) $26.55/year
b) $64.13/year
Step-by-step explanation:
a) <u>$7.64</u> . <u>1 ft³</u> . <u>50 gal</u> . <u>1 load </u> . <u>52 week</u> = $<u>26.55</u>
100 ft³ 7.48 gal 1 load 1 week 1 year year
The total cost per year is $26.55
b)<u>$7.64</u> . <u>1 ft³</u> . <u>17.2 gal</u> . <u>1 shower </u> . <u>365 days</u> = <u>$64.13</u>
100 ft³ 7.48 gal 1 shower 1 day 1 year year
The total cost per year is $64.13
Answer:
third option
Step-by-step explanation:
A right triangle can be considered as a special type
because the relationship of its sides can be described using the hypotenuse
formula:
c^2 = a^2 + b^2
or
c^2 = x^2 + y^2
where,
c is the hypotenuse of the triangle and is the side
opposite to the 90° angle
while a and b are the sides adjacent to the 90° angle
In the problem statement, we are given that one of the
side has a measure of 2 = x, while the hypotenuse is 5 = c, therefore calculating
for y:
y^2 = c^2 – x^2
y^2 = 5^2 – 2^2
y^2 = 21
y = 4.58
The natural number is the number before the decimal.
Therefore the answer is:
y = 4
