Answer: 6.6 miles
Step-by-step explanation:
Since he finished 22% of his skiing in the morning, that means he still has 78% (100% - 22%) of his skiing left.
The remaining 78% is equivalent to 23.4 miles. We need to know the total miles of the skiing. This will be:
78% of x = 23.4
0.78 × x = 23.4
0.78x = 23.4
x = 23.4 / 0.78
x = 30 miles
Since the total skiing is 30 miles and he has 23.4 miles left, the miles covered in the morning will be:
= 30 - 23.4
= 6.6 miles
In rectangle MNOP, MO = 4x - 10 and NP = 2x + 4.
What is the length of a diagonal?
Answer:
18
Step-by-step explanation:
From the rectangle, M O = NP
4x - 10 = 2x+4
4x-2x = 4 + 10
2x = 14
x = 14/2
x = 7
SInce MO and NP are the diagonal
Length of diagonal = 4x- 10
Length of diagonal = 4(7) - 10
Length of diagonal = 28 - 10
Length of diagonal = 18
hence the required length is 18

How do I find the domain and range of y= -(x-2)^2+3?
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.

A cyclist travels 5.8 km in 30 minutes.
What is his average speed in km/h?
Answer:
11.6km/hr
Step-by-step explanation:
You need to double 30 minutes to get an hour, so do the same with the distance.
5.8*2=11.6 km
11.6km/hr

The circumference of a circle is 8.44cm.
Find the length of the diameter.
Give your answer rounded to 2 DP.
Answer:
Diameter = 2.68cm
Step-by-step explanation:
Circumference of a circle = 2πr
Circumference of a circle = 8.44cm
π = 3.14
r = ?
Circumference of a circle = 2πr
8.44 = 2 * 3.14 * r
8.44 = 6.28r
r = 8.44/6.28
r = 1.3439490445859
Approximately
r = 1.34
Diameter = 2r
Diameter = 2 * 1.34
Diameter = 2.68cm
The area of the trapezium above is 22 cm².
What is the value of x ?
Answer:
4cm
Step-by-step explanation:
Given area= 22cm²
Height =4cm
Parallel sides = xcm and 7cm
Area of trapezium = ½( sum of parallel sides) x height
22cm² = ½(xcm+7cm)×4cm
22cm²= ½ ( x+7)cm x 4cm
opening the bracket
22cm²= 4x+28/ 2
cross multiply
44cm²=4x+28
4x=44-28
4x=16
x=4cm

Among the licensed drivers in the same age group, what is the probability that a 78-year-old was involved in an accident? Use the table below.
Answer:
C. 6.6%
Step-by-step explanation:
The probability of an event 'A' occurring, P(A) is given by the ratio of the number of times event A occurs to the some of all possible events
Mathematically, we have;
[tex]The \ probability \ of \ an \ event = \dfrac{The \ number \ of \ the \ required \ outcome}{The \ number \ of \ all \ possible \ outcomes}[/tex]
The number of drivers involved in an accident who are above 75 years = 13,321
The total number of drivers in accidents = (10,034 + 17,173+ 35,712+ 40,322 + 40,937 + 30,355 + 17,246 + 13,321) = 205,100
A 78-year-old is in the age group of 75 and older
∴ The probability that a 78-year-old licensed driver was involved in an accident = The probability that a 75 and older year-old licensed driver was involved in an accident = 13,321/205,100 ≈ 0.06495 = 6.5%
Therefore, the best option is option C. 6.6%

Find the area of the shaded region. Round to the nearest hundredths place when necessary.
please show work
Answer:
450.25 sq in
Step-by-step explanation:
Subtract area of triangle from area of circle
Area of Triangle:
need to get the radius (which we will use as the height) and double the radius to get the base
Pythagorean Theorem:
21² + 20² = c²
441 + 400 = c²
c = [tex]\sqrt{841}[/tex] which is 29
A(Δ) = 1/2(29)×14.5
= 210.25
Area of Circle:
A = π(14.5²)
= 660.52
Difference = 660.5 - 210.25 = 450.25

You multiply 72 by .8 because you have to change the percent into a decimal place to multiply it by. 0.8 is 80 hundredths and fractions are numbers out of 100. I hope I could help you :)
Determine a simplified expression to represent the area of shaded region within the figure below
Answer:
[tex](5x-3)^{2}[/tex] - (3x+1)(2x-1)
Step-by-step explanation:
Determine the area of the large square: (5x - 3)(5x - 3)
Determine the area of the small rectangle: (3x + 1)(2x -1)
Subtract the area of the small rectangle from the area of the large square to get the area of the shaded region.

Point R is located at (1, 2) on a coordinate grid. Point S is located at (4, 5) on the same
coordinate grid. What is the distance from point R to point S, rounded to the nearest tenth?
A. 3.2 units
B. 4.6 units
C. 7.6 units
D.
10.0 units
Answer:
4.2 units
most likely answer choice B
Step-by-step explanation:
(1, 2) and (4, 5)
To find the distance between two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Let's plug in what we know.
[tex]d = \sqrt{(4 - 1)^2 + (5 - 2)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(3)^2 + (3)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(9) + (9) }[/tex]
Add.
[tex]d=\sqrt{18}[/tex]
Evaluate the radical.
d = 4.24
Round to the nearest tenth.
d = 4.2 units
*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.
Hope this helps!

Can anyone answer this ASAP
Answer:
650 ft^2
Step-by-step explanation:
Without the gap, the area of the rectangle is 20ft x 35ft = 750 ft^2. The gap is a square having 10ft on the side so its area is 10ft x 10ft = 100 ft^2. Subtracting the area of the square gap from the rectangle gives you 650 ft^2.

A drawer contains 2 Red Socks, 7 White Socks, and 9 blue sock Without looking, you draw out a sock and then draw out a second sock without returning the first sock. What is the probability that the first sock and the second sock are both red?
Answer:
1/153
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
probability that the first sock and the second sock are both red = (number of red socks /total number of socks) x (number of red socks /total number of socks)
At the first pick, the probability = 2/18
At the second pick because there is no replacement, there would be 1 red socks and 17 socks = 1/17
2/18 x 1/17 = 1/153

Answer:
[tex]\huge\boxed{(2,\ 3);\ (-1,\ 6)}[/tex]
Step-by-step explanation:
[tex]f(x)=x^2-2x+3\to y=x^2-2x+3\\f(x)=-x+5\to y=-x+5\\\\\left\{\begin{array}{ccc}y=x^2-2x+3&(1)\\y=-x+5&(2)\end{array}\right[/tex]
substitute (1) to (2):
[tex]x^2-2x+3=-x+5[/tex] add x to both sides
[tex]x^2-2x+x+3=-x+x+5[/tex]
[tex]x^2-x+3=5[/tex] subtract 5 from both sides
[tex]x^2-x+3-5=5-5[/tex]
[tex]x^2-x-2=0\\\\x^2+x-2x-2=0\\\\x(x+1)-2(x+1)=0\\\\(x+1)(x-2)=0\iff x+1=0\ \vee\ x-2=0\\\\\boxed{x=-1\ \vee\ x=2}[/tex]
substitute the values of x to (2):
[tex]x=-1\\\\y=-(-1)+5=1+5=6\\\\\huge\boxed{(-1,\ 6)}\\\\x=2\\\\y=-2+5=3\\\\\huge\boxed{(2,\ 3)}[/tex]
