A car travels for 2 hours 15
minutes at an average speed
of 64 mph. Calculate the
distance travelled.
Answer:
231.746 km
Step-by-step explanation:
Formula: [tex]distance = speed[/tex] × [tex]time[/tex]
Solution: To solve for distance use the formula for distance
Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.
Firstly, convert the time from hours to minutes
2 hr 15 min = 2.25 hr
or 2.25 hr = 135 min
Now, use the formula:
135 × 64 = 8640
In km, the distance traveled is 231.74

Step-by-step explanation:
The measure of minor arc FD is 51x + 1
The measure of major arc FD is 360 - (51x + 1)
m<E = ½[m(major arc FD) - m(minor arc FD)]
36x + 5 = ½[360 - (51x + 1) - (51x + 1)]
72x + 10 = 360 - 51x - 1 - 51x - 1
174x = 348

Graph y=3x^2 show all steps please
Answer:
In image
Step-by-step explanation:
if y=3x^2
if x is 1 y is 3 because if you substitute x for 1, 1^2 = 1, And 3•1 = 3
if x is 2 y is 12 because if you substitute x for 2, 2^2 = 4 and 3•4 =12
Keep going using this formula, You can go into the negatives by substituting x for a negative number aka -1 or -2

what is the interquartile range of the sequence 5,5,8,8,13,14,16,16,19,22,23,27,31 ?
Answer:
The Interquartile range is 10.
Step-by-step explanation:
First, we will need to find the mean, the mean of this sequence is 16, you will now need to find quartile 1 and quartile 3. Quartile 1 is 13, and quartile 3 is 23. Lastly, subtract Quartile 3 and Quartile 1 will be the answer.
So, 23-13=10
The Answer will be 10, the interquartile range is 10.

The table shows a student's work when solving the equation 8x-(4x-3)=5.
Which statemen ais true?
Answer:
x = 1/2
Step-by-step explanation:
8x-(4x-3)=5
Distribute the minus sign
8x -4x +3 = 5
Combine like terms
4x+3 =5
Subtract 3 from each side
4x+3-3 = 5-3
4x = 2
4x/4 = 2/4
x = 1/2

Which of the following pairs of events are disjoint (mutually exclusive)?
a) A: odd numbers; B: the number 5
b) A: even numbers; B: numbers greater than 10
c)A: numbers less than 5; B: all negative numbers
d)A: numbers above 100; B: numbers less than -200
Answer:
d
Step-by-step explanation:
d because there are no numbers common to both sets
Disjoint sets are those sets that have no common values between the sets.
A: numbers above 100; B: numbers less than -200 is a disjoint set.
Option D is the correct answer.
What is a set?A set is a collection of items where there are operations such as:
Union of sets, the intersection of sets, complements of sets.
We have,
Disjoint sets are those sets that have no common values between the sets.
a) A: odd numbers; B: the number 5
Set A = {1, 3, 5, 7, 9,.....}
Set B = {5}
A ∩ B = {5}
This is not a disjoint set.
b) A: even numbers; B: numbers greater than 10
A = {2, 4, 6, 8, 10, , , }
B = {11, 12, 13, 14, 15, 16, 18,,,,,}
A ∩ B = {12, 14, 16, 18,,,}
This is not a disjoint set.
c) A: numbers less than 5; B: all negative numbers
A = {, , ,, -3, -2, -1, 0, 1, 2, 3, 4}
B = {, , , , -3, -2, -1}
A ∩ B = { , , , , -3, -2, -1}
This is not a disjoint set.
d) A: numbers above 100; B: numbers less than -200
A = {101, 102, 103, 104, ,,,,,,}
B = {, , , , -204, -203, -202, -201}
A ∩ B = Ф
There are no common values between set A and set B.
This is a disjoint set.
Thus,
A: numbers above 100; B: numbers less than -200 is a disjoint set.
Option D is the correct answer.

A skateboarder goes off of a ramp at a speed of 52 ft./s. The ramp is 5 ft. above the ground with a 30°
angle of elevation. Which set of parametric equations represents the skater's jump? The acceleration due
to gravity is 32 ft/s^2.
The set of parametric equations representing the skater's jump is:
x = 52t
y = 5 + 16t²
We have,
Let's denote the time as t.
Horizontal motion:
The skateboarder's horizontal velocity remains constant throughout the jump, so the horizontal position (x) can be represented as:
x = vt
where v is the horizontal velocity, which in this case is 52 ft/s.
Vertical motion:
The vertical position (y) can be determined using the equations of motion under constant acceleration.
The skateboarder experiences acceleration due to gravity (g) acting downward.
The initial vertical position is 5 ft, and the initial vertical velocity is
0 ft/s.
Using the equation of motion:
[tex]y = y_0 + vy_0t + 0.5gt^2[/tex]
Substituting the given values:
y = 5 + 0t + 0.5(32)t²
y = 5 + 16t²
Thus,
The set of parametric equations representing the skater's jump is:
x = 52t
y = 5 + 16t²
