A powerboat heads due northwest at 13 m/s with respect to the water
across a river that flows due north at 5.0 m/s.
What is the velocity (both magnitude and direction) of the motorboat with
respect to the shore?
9514 1404 393
Answer:
16.9 m/s N 32.9° W
Step-by-step explanation:
The resultant magnitude can be found from the law of cosines. The internal angle between the boat's heading and the river flow is 135°, so the magnitude of the boat's net speed is ...
v² = 5² +13² -2·5·13·cos(135°) ≈ 285.924
v = 16.9093 . . . . m/s
The angle (α) between the boat's heading and the resultant velocity can be found from the law of sines.
sin(α)/5 = sin(135°)/16.9093
α = arcsin(5/16.9093×sin(135°)) ≈ 12.07°
The boat's actual heading will be this angle less than the 45° angle the heading makes with due North.
45° -12.07° = 32.93°
The boat's velocity with respect to shore is about ...
16.9 m/s N 32.9° W

A new sidewalk will be 4 feet wide, 240 feet long, and filled to a depth of 9 inches (0.75 foot) with concrete. How many cubic yards of concrete are needed?
Answer: The number of cubic yards of concrete that are needed is 720.
Step-by-step explanation: The same formula for this type of shape stays the same: l*w*(h or d).
240 * 4 = 960
960 * 0.75 = 720
The amount of cubic yard of concrete needed is about 720 cubic foot
How to calculate the volume of box?The formula for calculating the volume of the concrete is expressed as:
V = lwh
l is the length =240feet
w is the width = 4 feet
h is the depth = 0.75foot'
Determine the volume
V = 240 * 4 * 0.75
V = 720 cubic feet
Hence the amount of cubic yard of concrete needed is about 720 cubic foot

What is the length of z? (Round to the nearest tenth)
Answer:
z = 10.8
Step-by-step explanation:
[tex]9^{2} + 6^{2} = c^{2}[/tex]
81 + 36 = [tex]c^{2}[/tex]
117 = [tex]c^{2}[/tex]
c = [tex]\sqrt{117}[/tex]
c = 10.8
c = z

If a girl has 5pink bows 1blue bow 4 purple bows in a box what is the probability of getting a purple bow
Answer:
40% or 4/10
Step-by-step explanation:
First you want to find the total amount of bows which is 10. 4 of those 10 bows are purple. So you can write it as a fraction 4/10 or a percent 40%
hi
first, you must count the number of bows :
5 +1+4 = 10
purple are 4 among 10 so the probability of picking a purple bow is 0.4

It is known that a laptop company's average production is given by P(t) = (150t) / (3t+20), where
t is the time (in days). How many days will it take the company to produce 30 laptops?
Answer:
10 daysStep-by-step explanation:
Step one:
given that the expression for the company's average production is
[tex]P(t) = (150t) / (3t+20)[/tex]
Required:
t, when P=30
Step two:
substituting we have
30=150t/3t+20
cross multiply we have
30(3t+20)=150t
90t+600=150t
collect like terms
600=150t-90t
600=60t
divide through by 60
t=600/60
t=10 days
it will take the company 10 days

Answer:
Emily pays 10.40 and Andy pays 8 dollars
Step-by-step explanation:
So let's start with Emily, she need 21 feet of wire, so we convert this to inches so; [tex]1foot=12inches\\ 21feet=(12inches)*21=252inches[/tex] but it's not listed on the tableSo we try to find the closest approximation to 252 inches which we get by adding 100 inches and 160 inches to get 260 inchesSo Emily will pay the cost of those to lengths so 100 inches cost 4.00 dollars and 160 inches costs 6.40 dollarsso she pays 4.00+6.40=10.40 dollarsNow for Andy we do much the same and find the inches in 11 yards[tex]1 yard=36inches\\ 11yards=(36inches)*11=396inches[/tex] this is also not listedSo we get the closest approximation, which is 4 of the 100 inch wires, so we get 400 inches costing 4*4.00=8 dollarsWhat’s the answer to this multi step equation? -3(12x+9)=9
