Answer:
3 hours
Step-by-step explanation:
Assuming that when the problem says "day" it refers to the hours of wakeness. The problem is essentially asking to find 20% of 15.
First, convert 20% to decimal form. To do this, divide (20) by 100, this is because a percent is out of 100.
20 / 100 = 0.2
Now multiply the hours of wakeness by the percent as a decimal;
15 * 0.2 = 3

in the interval 0° ≤ x ≤360°, find the values of x for which tan x =1.3562 Give your answers to the nearest degree
Answer:
The answers are 54 degrees and 234 degrees
Step-by-step explanation:
mathematically we have the tan positive on only two axes
these are the first (0-90) degrees and the 3rd quadrant (180-270)
We start by find the arc tan of the angle value
Thus;
x = arc tan (1.3562)
x = 54 degrees
On the third quadrant, we have it that;
180 + 54 = 234 degrees

Mike took a taxi from his home to the airport. The taxi driver charged an initial
fee of $6 plus $3 per mile. The total fare was $24, not including the tip. How many
miles did mike travel by taxi on this ride?
A. 2
B. 6
C. 8
D.10
Answer:
B. 6
Step-by-step explanation:
SInce the total amount paid by Mike was $24, you subtract the initial amount he paid ($6) which leaves you with $18. Since the taxi driver charges $3 per mile you divide $18 by $3 to get 6 so that means Mike travel 6 miles.

How to solve ∠GHJ and ∠JHK are adjacent angles. ∠GHK measures 73°.
Answer:
GHJ = 19
JHK = 54
Step-by-step explanation:
first we setup an equation 73=x+2+3x+3 and solve for x
step 1 combine like terms
73=4x+5
step 2 subtract each side by 5
68=4x
step 3 divide each side by 4
x=17
then if we want to find what each angle equals we just plug in 17 to x
17+2=19 so angle GHJ equals 19
3x17=51+3=54 so angle JHK equals 54

The true description of the figure here are:
x = 8MN = 52DHow to solve for the proof of the figureWe have x to be = 8
The value of MN is said to be 5x + 12
We have to see if 5x + 12 = MN = 52 given that X is 8
We then insert the value
5 * 8 + 12 =
40 + 12 = 52
Hence it is confirmed that the value of x is 8, and MN is 52.

y is directly proportional to the square root of x
If y = 32 when x = 64 find,
y when x = 25
Please help
Answer:
y = 20
Step-by-step explanation:
Given y is directly proportional to [tex]\sqrt{x}[/tex] , then the equation relating them is
y = k[tex]\sqrt{x}[/tex] ← k is the constant of proportion
To find k use the condition y = 32 when x = 64, then
32 = k[tex]\sqrt{64}[/tex] = 8k ( divide both sides by 8 )
4 = k
y = 4[tex]\sqrt{x}[/tex] ← equation of proportion
When x = 25, then
y = 4[tex]\sqrt{25}[/tex] = 4 × 5 = 20
The base of a rectangular tank measures 50 cm by 40 cm. It contains 60 liters of water when it is ¾ full. Find the height of the tank. (1 liter = 1000 cm3)
Answer:
40 cm
Step-by-step explanation:
Let h = height of the tank
V = lwh
(3/4)V = 60 liters = 60000 cu cm
50(40)h = 2000h = Volume of the tank
(3/4)2000h = 1500h = (3/4)V = 60000
h = 40 cm.
A Purse cost $75.00 at Macy’s with a 25% discount. What is the sale price with 7% tax?
Answer: $60.1875
Step-by-step explanation:
Since we are told that a purse cost $75.00 at Macy’s with a 25% discount. The sale price will be:
= $75 - (25% × $75)
= $75 - (0.25 × $75)
= $75 - $18.75
= $56.25
We will then add the 7% tax and this will be:
= $56.25 + (7% × $56.25)
= $56.25 + (0.07 × $56.25)
= $56.25 + $3.9375
= $60.1875
Chris rode his bike 4 miles west and then 3 miles south. What is the
shortest distance he can ride back to the point where he started?
Answer:
5 miles
Step-by-step explanation:
This is because if you draw a line going west and label it as 4 miles, then draw another line going south and label it 3 miles, you form a right angle, right? So, the fastest way to go back would be taking a diagonal-like route back to the beginning. Does this shape look familiar to you? Right! It's a right triangle. And do the numbers 3, 4, and 5 sound familiar to you? Yup, it's a Pythagorean triplet. If the legs of a right triangle are 3 and 4, the hypotenuse is 5. Why am I saying this? Because, in the drawing you just did, the 4 miles west and 3 miles south were the legs, and the diagonal path back to the beginning is the hypotenuse. Get it now?

A cashier at Giorgio's Grocery Store gets paid $8 per hour for shifts of 6 hours or less and $12 per hour for working shifts over 6 hours long. Which function best represents this situation?
Given :
A cashier at Giorgio's Grocery Store gets paid $8 per hour for shifts of 6 hours or less.
And $12 per hour for working shifts over 6 hours long.
To Find :
A function best represents this situation.
Solution :
Let, number of hours is h and amount paid is y .
For, h ≤ 6
y = 8h
For, h > 6
y = 12h
Therefore, function representing this is :
y( h ) = 8h , x ≤ 6
12h , x > 6
Hence, this is the required solution.

A new laptop costs around $850. What
is a reasonable amount of sales tax you
would expect to pay (estimate)?
Answer:
Depends on your sales tax rate where you live.
Lets call your sales tax rate X%
then it would be multiplied b y the $850 and that would be added back to the $850.
Example:
If your sales tax rate were 10%
then it would be .10 x $850 =$85
Now add the $85 to the $850 and your total would be $945
P.S. Some localities offer sales tax free weekends for school supplies.
