Elena and her mom are on a road trip outside the United States. Elena sees this road sign (Maximum 80). Elena's mom is driving 75 miles per hour when she gets pulled over for speeding. The police officer explains that 8 kilometers is approximately 5 miles. If the speed limit is 80 kilometers per hour, and Elena's mom was driving 75 miles per hour, was she speeding? How many kilometers per hour was she OVER THE SPEED limit of 80kph?
Given :
Maximum speed limit, s = 80 km/hr
Elena's mom is driving at u = 75 mph.
The police officer explains that 8 kilometres is approximately 5 miles.
To Find :
Was she speeding and by how many km/hr.
Solution :
It is given that 8 km = 5 miles
So,
[tex]1\ miles=\dfrac{8}{5}\ km\\\\1\ miles = 1.6\ km[/tex]
Now, Speed of Elena's mom in km/hr is :
[tex]Speed =\dfrac{75\ miles\times\dfrac{1.6\ km}{1\ miles} }{1 \ hour}\\\\Speed = \dfrac{120\ km}{1 \ hour}\\\\Speed = 120\ km/hour[/tex]
Yes, she is over speeding and by ( 120 - 80 ) = 40 km/hr.
Hence, this is the required solution.
Elena's mom was driving at 120 km per hour, with which she was effectively speeding, exceeding the allowed speed by 40 km per hour.
To determine if Elena's mom was speeding and to determine how many kilometers per hour was she over the speed limit of 80kph the following calculation should be performed:
5 = 8 75 = X 75 x 8/5 = X 120 = X
Therefore, Elena's mom was driving at 120 km per hour, with which she was effectively speeding, exceeding the allowed speed by 40 km per hour.

zachary has six times as many nickels as dimes and four times as many quarters as dimes. zachary has a total of ninety-nine nickels, dimes, and quarters. The total value of the coins is $12.60. How many of each coin does he have?
Answer:
nickels: 54dimes: 9quarters: 36Step-by-step explanation:
The ratio of nickels to dimes to quarters is given as ...
N : D : Q = 6 : 1 : 4
The total number of ratio units is 6 +1 +4 = 11. The total number of coins is given as 99, so each "ratio unit" must represent 99/11 = 9 coins. That is, the actual coin count ratios are ...
N : D : Q = 54 : 9 : 36
Zachary has 54 nickels, 9 dimes, and 36 quarters.

What value belongs next to the 1 in the table? What does it mean in this context?
Answer:
The number next to 1 is 2.5.
It means 2.5 dimes are in 1 quarter (1 quarter = 2.5 dimes)
Step-by-step explanation:
The value next to 1 in the table above = number of dimes we have in 1 quarter.
Let the value next to 1 be "x".
That is:
1 quarter = x dimes
If 4 quarters = 10 dimes, then,
Cross multiply to find, how many dimes, x is equal to.
Thus:
1*10 = 4*x (cross multiplication)
10/4 = 4x/4 (dividing both sides by 4)
2.5 = x
The number next to 1 is 2.5.
It means 2.5 dimes are in 1 quarter (1 quarter = 2.5 dimes)

(PLS HELP)The diameter of a cylindrical water tank is 12 ft, and its height is 17 ft. What is the volume of the tank?
Use the value 3.14 for л, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer: The volume is equal to 1922.65.
Step-by-step explanation:
Diameter is 12 ft, height is 17 ft.
V = πr2h
V = πr2h = π·62·17≈ 1922.65
The volume of the tank is approximately 1814 cubic feet.
What is a cylinder?A cylinder is a 3-D figure that has a radius and a height.
The volume of a cylinder is given as πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume.
= 3.14 x 2 x 2 x 5
= 62.8 cm³
We have,
The formula for the volume of a cylinder is:
V = πr²h
where V is the volume, r is the radius, h is the height, and π is a constant equal to approximately 3.14.
We are given the diameter of the tank, which is 12 feet.
The radius is half the diameter, so:
r = 12/2 = 6 feet
We are also given the height of the tank, which is 17 feet.
Substituting these values into the formula, we get:
V = πr²h
V = 3.14 × 6² × 17
V ≈ 1814
Therefore,
The volume of the tank is approximately 1814 cubic feet.

Answer: y > x + 4
Step-by-step explanation:
First lets find a linear equation for the dividing line, in the form:
y = mx + b
We know that b is 4, since this is the y-intercept
lets use any point on the graph, I'll use (-4, 0):
y = mx + 4
0 = m(-4) + 4
-4 = -4m
m = 1
So the slope is 1. Our completed formula for the line is:
y = x + 4
Since the left side of this graph is shaded, we know it will either be > or ≥. Since the line is also dotted we know it is denoted by a simple ">" sign.
So our completed inequality equation is: y > x + 4
Hope this helped!
Answer:
[tex]\sf y > x+4[/tex]
Step-by-step explanation:
Choose 2 points on the line: (-4, 0) and (0, 4)
Let [tex]\sf (x_1,y_1)=(-4,0)[/tex]Let [tex]\sf (x_2,y_2)=(0,4)[/tex][tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-0}{0-(-4)}=1[/tex]
point-slope form of linear equation: [tex]\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-0=1(x-(-4))[/tex]
[tex]\implies \sf y=x+4[/tex]
Solid line : ≤ or ≥
Dashed line: < or >
Therefore as the line is dashed, and the shading is above the line,
