Answer:
Map scale is 1:400000 => 1 cm on the map represents 400000 cm (4 km) on the ground.
So, 18 km on the ground is represented by 18/4 cm or 4.5 cm on the map.
Answer: 4.5 cm
Step-by-step explanation:
The clear and easiest way to deal with this problem is to convert all measurements to centimeters because that is the stated unit to be used. In SI, the metric prefixes can be written as exponents. The prefix kilo corresponds to 10^3 while the prefix centi corresponds to 10^-2 so 18 km = 18 x 10^3 m = 18 x 10^3 x 10^2 cm= 18 x 10^5 cm.
The number 18 x 10^5 cm is to be reduced to 400,000 times in the map and it means a process of division is to be performed. Dividing 18 x 10^5 cm by 400,000 gives a quotient of 4.5 cm.
This means that an actual distance of 18 km, on the map it just corresponds to 4.5 cm distance if the scale used is 1:400,000.

Solve: 5x-3+2x = 5x+3 show your work
Answer:
x = 3
Step-by-step explanation:
5x - 3 + 2x = 5x + 3
subtract 5x from both sides
5x - 5x - 3 + 2x = 5x - 5x + 3
-3 + 2x = 3
add 3 to both sides
-3 + 3 + 2x = 3 + 3
2x = 6
divide both sides by 2
2x/2 = 6/2
x = 6/2
x = 3
Answer:
x = 3
Step-by-step explanation:
5x - 3 + 2x = 5x + 3. that is
7x - 3 = 5x + 3 ( subtract 5x from both sides )
2x - 3 = 3 ( add 3 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3

Step-by-step explanation:
The hull speed of a boat in knots per hour is determined by the length of the waterline. The waterline is the length of the boat that is actually in the water. This relationship can be modeled by the function h=1.34l where h is speed of the boat and L is the length of the waterline in feet. What is the length of the waterline if the hull speed is 4 knots
Answer:
The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.
Step-by-step explanation:
Let the function [tex]h = 1.34\cdot l[/tex], where [tex]l[/tex] is the length of the waterline, measured in feet and [tex]h[/tex] is the hull speed of the boat, measured in knots per hour. If we know that [tex]h = 4\,\frac{kt}{h}[/tex], then the length of the waterline is:
[tex]l = \frac{h}{1.34}[/tex]
[tex]l = \frac{4}{1.34}[/tex]
[tex]l = 2.985\, ft[/tex]
The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.

Which of the following equations, where d is distance in miles and t is time in hours, represents a speed that is less than that of the leatherback sea turtle?
Answer:
Options (A) and (B)
Step-by-step explanation:
Speed of the leatherback sea turtle = 21.92 miles per hour
If the sea turtle travels distance 'd' in 't' hours,
Speed [tex]=\frac{\text{Distance}}{\text{Time}}[/tex]
Speed that is less than 21.92 mph are 2.192 mph and 20 mph,
For speed = 20 mph
20 = [tex]\frac{d}{t}[/tex]
d = 20t
For speed = 2.192 mph
2.192 = [tex]\frac{d}{t}[/tex]
d = 2.192t
Therefore, Options (A) and (B) are the correct options.

Tatyana earns $825 per week, but a Social Security tax of 7.51% and a State
Disability Insurance of 1.2% are deducted from her earnings. Assuming no other
deductions, how many dollars does Tatyana take home each week?
Answer:
$753.14
Step-by-step explanation:
7.51% + 1.2% = 8.71%
8.71% off of $825 is $753.14
Answer:
$753.1425 or $753.14
Step-by-step explanation:
7.51% of $825 is $61.96 (You do this by taking the original of $825 and multiplying it by the decimal .0751 (which is the decimal form of 7.51%)
And 1.2% of $825 is $9.9 (Same formula from above, but multiply by .012)

I need help with this if you can please send help my grade depends on it
Answer:
y= 77° x=103°
Step-by-step explanation:
x=103° Alternate angles are equal
y=77° angles on a straight line sum to 180° (180°-103°=77°)
Answer:
For x, we can justify that x=103° and for y, we can justify that it equals 77°.
Step-by-step explanation:
X°: VERTICAL ANGLE THEOREM, or if angles are opposite of each other and are formed by two intersecting straight lines, then they are congruent.
Thus, x°=103°
Y°: SUPPLEMENTARY ANGLE THEOREM, or if two angles are supplementary to the same angle, then the two angles are said to be congruent.
Thus, y°=77°
