Answer:
m = 4 + 0.18b
Step-by-step explanation:
So, we are looking to find the total amount of money that Ariella earns.
$4.00 is what she initially gets paid.
plus 18%, 18 / 100 = 0.18
then b is the amount of total bill
so, we multiply the amount of percentage which is 18% to the amount of total bill which is b to get what she additionally earns after the customers paid the bill.
so initial pay is $4 + 18% which is 0.18 multiply to b, b represents the total bill.
$4 + 0.18b = m
Crook Island is 25 km due east of the Isle of Strutay.
Grass Rock is 21 km due south of Crook Island.
Emerald Cay is 19 km due east of Grass Rock.
What bearing should a ship sailing in a straight line from the Isle of Strutay to
Emerald Cay travel on?
Give your answer in degrees to 1 d.p
The bearing that the ship should take when sailing in a straight line from the Isle of Strutay to Emerald Cay is 25.38 degrees.
How to find the bearing ?To find the bearing from the Isle of Strutay to Emerald Cay, we can first find the total eastward distance and the total southward distance, and then use the arctangent function to find the angle.
Total eastward distance:
From Isle of Strutay to Crook Island: 25 km
From Grass Rock to Emerald Cay: 19 km
Total eastward distance = 25 km + 19 km = 44 km
Total southward distance:
From Crook Island to Grass Rock: 21 km
Now we can use the arctangent function to find the angle :
tan(θ) = (total southward distance) / (total eastward distance)
tan(θ) = 21 km / 44 km
θ = arctan (21/44) = 25.38°

Jim's speedboat can travel 21 miles upstream against a 3 mph current in the same amount of time it travels 23 miles downstream with a 3 mph current speed. Find the speed, in miles per hour, of the Jim's boat.
Answer:
69 mph
Step-by-step explanation
Let the speed of boat be x hence speed downstream is x+3 but speed upstream will be x-3
Speed is distance per unit time and time is same hence
24(x-3)=22(x+3)
24x-72=22x+66
2x=138
X=138/2=69
Therefore, the speed of boat is 69 miles per hour or
The boat in the problem travels different distances at different rates, but in the same amount of time for each trip. Distance is rate times time, d=r⋅t, which, solving for t, becomes
t=dr.
The trip against the current has rate r=s−3, so the time it takes to complete the trip is
t=20s−3.
The time it takes to complete the trip with the current is
t=22s+3.
The time to complete each trip is the same, so set the fractions equal to each other.
20s−3=22s+3
Multiply each side by (s−3)(s+3).
20(s−3)(s+3)(s−3)=22(s−3)(s+3)(s+3)
Simplify.
20(s+3)=22(s−3)
Distribute coefficients.
20s+60=22s−66
Combine like terms.
2s=126
Divide each side by 2 to find the solution,
s=69 mph.

A machinist creates a solid steel part for a wind turbine. The part has a volume of 1,015 cubic centimeters. Steel can be purchased for $0.29 per kilogram and has a density of 7.95 g/cm^{3}
If the machinist makes 500 of these parts, what is the cost of steel to the nearest dollar.
Thus, the cost of steel for making 500 solid steel part for a wind turbine is found as: Total Price = $1170.04 .
Explain about the density of material?Atmospheric gases move according to their densities as one material rises above another. It affects what floats and what starts to sink in a body of water. A estimate of how compressed matter is is what density means. How much "stuff" is crammed into an area, to put it simply.
It is a calculable and manipulable formula in mathematics. Density is used to discuss population in various fields, such as the social sciences.
Density = mass / volume
mass = density * volume.
density of steel = 7.95 g/cm³
volume of steel = 1,015 cm³
Unit rate = $0.29 per kilogram
mass = 7.95 * 1,015 g
mass = 8069.25 g
mass of 500 parts = 500* 8069.25
mass of 500 parts = 4034625 grams
mass of 500 parts = 4034625/1000 = 4034.625 kg
Total Price = mass of 500 parts *Unit rate
Total Price = 4034.625 * 0.29
Total Price = $1170.04
Thus, the cost of steel for making 500 solid steel part for a wind turbine is found as: Total Price = $1170.04 .

∆ACE is similar to ∆BDE because angle A is equal to angle B and angle is common.
What are similar triangles?Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
Therefore for ∆ACE to be similar to ∆BDE, their corresponding angles must be equal.
To show that the angles are equal,
<AEC = <DEB( vertically opposite angles )
<A = <B ( alternate angles)
therefore the value of angle C will be equal to the angle of D.

Please determine the follow arc measures
the answer of the subsets of the questions are Angle BTC is 198 degree
Arc bd is 90 degree,
How to find the Arc of the circle?
Since points T, C, B, D are on the boundary of a circle and meet at point P, we can conclude that P is the center of the circle.
Let's label the angles at the center of the circle. Since the angle between TCP is 128 degrees, we know that the angle TPC at the center of the circle is twice that, or 256 degrees. Similarly, since the angle between TPB is 90 degrees, we know that the angle TPB at the center of the circle is 180 degrees.
Let's also label the points where the arcs intersect the circle. The arc BD intersects the circle at points B, D, and P. The arc BC intersects the circle at points B, C, and P. The arc BTC intersects the circle at points B, T, C, and P. The arc TDC intersects the circle at points T, D, C, and P.
To find the arc BD, we need to find the central angle that corresponds to that arc. We can do this by adding the angles at the center of the circle that correspond to the arcs that intersect BD. In this case, those angles are TPB and TPC. So the central angle corresponding to arc BD is:
central angle for arc BD = angle TPB + angle TPC
central angle for arc BD = 180 degrees + 256 degrees
central angle for arc BD = 436 degrees
Therefore, the arc BD is a 436-degree arc.
To find the arc BC, we can follow the same process. The angles at the center of the circle that correspond to the arcs that intersect BC are TPB and TPC. So the central angle corresponding to arc BC is:
central angle for arc BC = angle TPB + angle TPC
central angle for arc BC = 180 degrees + 256 degrees
central angle for arc BC = 436 degrees
Therefore, the arc BC is also a 436-degree arc.
To find the arc BTC, we can again follow the same process. The angles at the center of the circle that correspond to the arcs that intersect BTC are TPB and TPC and the angle at the center of the circle that corresponds to arc BC. So the central angle corresponding to arc BTC is:
central angle for arc BTC = angle TPB + angle TPC + angle BPC
central angle for arc BTC = 180 degrees + 256 degrees + (360 degrees - angle BC)/2
central angle for arc BTC = 436 degrees + (360 degrees - angle BC)/2
To find angle BC, we can use the fact that the angles in a triangle sum to 180 degrees. So:
angle B + angle C + angle TCP = 180 degrees
Since TCP is 256 degrees, we can solve for angle BC:
angle B + angle C = 180 degrees - 256 degrees
angle B + angle C = -76 degrees
Since angles in a circle cannot be negative, we made an error somewhere. In fact, it is not possible for the given angles to correspond to a circle with center P. If we assume that the given angles are correct, we can conclude that there is no circle that contains all four points T, C, B, and D.

A pump moves 42 gallons in seven minutes find the unit rate
[tex]boommamama[/tex]
0.1 gallons per second is the unit rate in the given situation.
What is the unit rate?An item's unit rate is its price for one of them.
This is expressed as a ratio with a one as the denominator.
For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second.
Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.
The denominator of a unit rate is always 1.
Hence, divide the denominator by the numerator so that the denominator equals one in order to determine the unit rate.
The unit rate is 50km/5.5 hours = 9.09 km/hour, for instance, if 50km are traveled in 5.5 hours.
