If a bus driver leaves her first stop by 7:00 a.M., her route will take less than 35 minutes. If she leaves after 7:00 a.M., she estimates that the same route will take no less than 43 minutes. Write an inequality which represents the time it takes to drive the route, r.
Answers
Answer:
r < 35 or r ≥ 43
Step-by-step explanation:
We are told that when the bus driver leaves her first stop by 7:00 a.m., her route will take less than 35 minutes.
Since the time it takes to drive the route is r, then;
r < 35
Also, If she leaves after 7:00 a.M., she estimates that the same route will take no less than 43 minutes. Thus;
r ≥ 43
Thus;
r < 35 or r ≥ 43
The price of a television is $245. The sales tax rate is 8%. What is the amount of sales tax?
Answers
Answer:
$19.60
Step-by-step explanation:
245 is 100% of the total.
x is 108% of the total.
245/100 = x/108
245(108) = 26460
26460/100 = 264.6
264.6 - 245 = 19.6

is (0,0) a solution to the equation y=3x
Answers
=========================================================
Explanation:
The point (0,0) means x = 0 and y = 0 pair up together.
Recall that any point is always of the form (x,y).
If we plug x = 0 and y = 0 into the equation, we end up with,
y = 3x
0 = 3*0
0 = 0
We get the same thing on both sides, so we have a true equation.
Since we have a true equation, we've shown that (0,0) is a solution.
Visually this indicates (0,0) is on the line y = 3x. Put another way, the line y = 3x goes through the origin.

water to a depth of 1.8 m. Cal culate the surface area inside the tank that is not in conta
with water.
Answers
Answer:
16.64 m
Step-by-step explanation:
Subtract the depth of the water from the height of the tank (0.6) and use this measurement for height instead. then calculate l•h•2+w•h•2+l•w
(we multiplied the length and height and the width and height by two since there’s two sides with the same measurement for each)

What is the gravitational PE of the same 61.2 kg person standing on the 6th floor (Each story is 2.5 m high)?
Answers
Answer: U is the change in PE, m is the mass raised through a distance h. So, given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.

Find the surface area of this cylinder using pie.
Answers
Answer:
Thus, the surface area of a cylinder involving pie is:
[tex]\:\:\:A=36\pi \:[/tex] in²
or
[tex]A\approx 113.1[/tex] in²
Step-by-step explanation:
Given
radius = r = 2 in height = h = 7 inUsing the formula to determine the surface area of a cylinder:
[tex]A=2\pi \:rh+2\pi \:r^2[/tex]
[tex]A=\left(2\times \pi \times \:2\times 7\right)+\left(2\times \pi \times \:2^2\right)\:[/tex]

We are given the diameter, so solve for the radius:
[tex]d = 2r\\\\10 = 2r\\\\r = 5 ft[/tex]
Use the given height and radius to solve for the volume:
[tex]V = 6(5^{2}\pi )\\V = 6 * 25\pi \\\\V = 471 cu ft[/tex]
