1 1/4 hrs 5/4 hrs
----------- = ---------------- = 1/4 hr per day
5 days 5 days
Answer:
73
Step-by-step explanation:
Since DA is the diameter, this means that you can divide the circle into two half-circles. You will solve with the right half-circle. A half-circle has a 180 total degrees. Add up the values given and solve for x.
(2x) + (7x - 4) + (85) = 180
2x + 7x - 4 + 85 = 180
9x - 4 + 85 = 180
9x + 81 = 180
9x = 99
x = 11
Now that you have the value of x, solve for m∠CZB.
m∠CZB = 7x - 4
m∠CZB = 7(11) - 4
m∠CZB = 77 - 4
m∠CZB = 73
Answer:
1.18b
Step-by-step explanation:
Jacob had lunch at a restaurant and his bill was b.
Now, Jacob leaves 18% of his bill amount as a tip.
So, the tip amount at the rate of 18% of the bill amount will be 
Therefore, the total cost of Jacob for the lunch will be b + 0.18b = 1.18b. (Answer)
You can make this into a fraction, and then simplify it.
15/10, right?
15/10 = 3/2
Then compare 3/2 to the rest of the equation
3/2 = x/16
2 * 8 = 16
so
3 * 8 = x
x = 24
Kim would put x number of pizza slices on her pizza.
So she would be putting on 24 slices on her pizza.
The
equation of velocity of sound in air is v = 20 √(273 + t). In this problem, we
need to find the temperature when the velocity is 329 meters/s. You need
to measure the time it takes a sound to travel a
measured distance in order to measure its speed in air.
Given:
Velocity
of sound in air equation = v = 20 √(273 + t)
Velocity
= 329 m/s
To
solve:
V = 20 √(273 + t)
<span>
329 = 20 * sqrt(273 + t)</span>
<span>
16.45 = sqrt(273 + t)</span>
<span>
273 + t = 16.45^2</span>
<span>
t- 16.45^2-273</span>
<span>
t = -2.4 degrees Celsius</span>
<span>So, the
temperature when the velocity is 329 meters per second is -2.4 degrees Celsius.</span>
