during the first 60 seconds of a rocket launch after takeoff, a rocket traveled 208 kilometers in 50 minutes at a constant rate. suppose a penny is dropped from a skyscraper and could travel 153 kilomaters in 1/2 hours at a constant rate. which of these objects has a faster unit rate per hour?
Answers
The unit rate of the penny dropped is faster than the rocket.
How to find unit rate?Unit rate is the ratio of two different units, with denominator as 1.
Therefore, rocket travelled 208 kilometres in 50 minutes at a constant rate and the penny dropped from a skyscraper could travel 153 kilometres in 1/2 hours at a constant rate.
The object that has the faster rate between the two can be found as follows:
50 minutes = 0.833333 hours
Rate of the rocket = 208 / 0.833333
Rate of the rocket = 249.60009984
Rate of the rocket = 249.60 km/hr
Rate of the penny dropped = 153 / 0.5
Rate of the penny dropped = 306 km/hr
Rate of the penny dropped = 306 km / hr
Therefore, the unit rate of the penny dropped is faster than the rocket.

some birds migrate 20,000 miles. if 1 mile equals 1.6 km, calculate the distance these birds fly in km
Answers
If 1 mile equals 1.6 km, the distance these birds fly is 32000km.
Here we have,
Total miles = 20,000
Given, 1 mile = 1.6 kilometer
Thus, total km travel = 20000 x 1.6
Total km travel = 32000 km
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement.
Thus, some bird species travel 20,000 miles. These birds travel 32000 kilometers if a mile is equal to 1.6 kilometers.

44 - (2c + 3) = 4(c + 5) + c
solve the equation
Answers
Step 1: 44 - 2c - 3 = 4(c + 5) + c
When there is a in front of an expression in parentheses, change the sign of each term in the expression
Step 2: 44 - 2c - 3 = 4c + 20 + c
Distribute through the parentheses
Step 3: 41 - 2c = 4c + 20 + c
Subract the numbers
Step 4: 41 - 2c = 5c + 20
Collect the terms
Step 5: 41 - 2c - 5c = 20
Move variable to the left-hand side and change its sign
Step 6: -2c - 5c = 20 - 41
Move constant to the right-hand side and change its sign
Step 7: -7c = 20 - 41
Collect the terms
Step 8: -7c = -21
Calculate the difference
Lastly: Divide both sides of the equation by -7

Step-by-step explanation:
Assuming that items are on the x axis and revenue is on the y axis we can predict that for every 1 item produced the revenue is $3.
Technically speaking you can write the coordinate point as:
(1 item, 3 dollars in revenue)
Therefore, letter A would be correct.

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis
Other possible equations of line are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a the point (1, 3) represent on the graph.
Assume that we represent the item produced is mentioned along the [x] - axis and revenue generated is along the [y] - axis. Since, the graph is not given, we can assume that any one of the given condition is true -
It shows for every 1 item produced the revenue is $3.It shows that the revenue is a constant rate of $1.Therefore, we can say that any of the two given conditions are true -

Which equation represents the line that passes through the points (4, 6) and (−2, −1)?
Answers
Find the slope first by using rise/run
[tex]m=\frac{6-(-1)}{4-(-2)}\\m=\frac{6+1}{4+2}\\m=\frac{7}{6}[/tex]
[tex]y=mx+b\\y=\frac{7}{6}x+b[/tex]
We need to find the y-intercept. Substituting one of given ordered pairs. I will use (-2,-1).
Substitute x = -2 and y = -1 in the equation.
[tex]-1=\frac{7}{6}(-2)+b\\-1=\frac{7}{-3}+b\\-1=-\frac{7}{3}+b\\-1+\frac{7}{3}=b\\b=\frac{4}{3}[/tex]
Thus the y-intercept is 4/3.
From y = mx+b, the equation is.

The histogram represents the distribution of the number of seconds it took for each of 50 questions to find the answer to a trivia question the internet. which interval contains the median.
Answers
The interval that contains the median 25.5 is
(5 - 10)
What is a median?The median is the value that's exactly in the middle of a dataset when it is ordered.
We have a histogram as given below.
We need to make a table of class intervals and their frequency:
class interval frequency
0-5 22
5-10 5
10-15 9
15-20 9
20-25 5
25-30 1
We also need to find the cumulative frequency.
class interval frequency cumulative frequency
0-5 22 22
5-10 5 22 + 5 = 27
10-15 9 27 + 9 = 36
15-20 9 36 + 9 = 45
20-25 5 45 + 5 = 50
25-30 1 50 + 1 = 51
Now,
The number of questions = 50 ( even number)
Median:
= (50 + 1) / 2
= 51 / 2
= 25.5
We need to select the cumulative frequency where it is greater than the median.
So we have 27 which is at the interval (5 - 10).
Thus the interval that contains the median 25.5 is (5 - 10)

Irrational numbers are a subset of real numbers that are not rational numbers, rational numbers comprises integers and non-integers. In this case, square roots are one of the most known cases of irrational numbers. Now we proceed to check if each choice represents indeed an irrational number by algebraic handling:
Case A
√4 + √16 = 2 + 4 = 6
Case B
√5 + √36 = √5 + 6
Case C
√9 + √24 = 3 + √(6 × 4) = 3 + 2√6

Graph a line that contains the point (-5,-3) and has a slope of -2
Answers
Given:
The line contains the point (-5,-3) and has a slope of -2.
To find:
The graph of the line.
Solution:
The line contains the point (-5,-3) and has a slope of -2. So, the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
[tex]y-(-3)=-2(x-(-5))[/tex]
[tex]y+3=-2(x+5)[/tex]
[tex]y+3=-2x-10[/tex]
Subtracting 3 from both sides, we get
[tex]y=-2x-10-3[/tex]
[tex]y=-2x-13[/tex]
So, the equation of line is [tex]y=-2x-13[/tex].
Putting x=0, we get
[tex]y=-2(0)-13[/tex]
[tex]y=0-13[/tex]
[tex]y=-13[/tex]
It means, the line also passes through (0,-13).
Plot the points (0,-13) and (-5,-3) on a coordinate plane and connect them by a straight line.

The camera's horizontal distance of 26 feet from the the focus point on the floor.How high above the floor is the camera Round your answer to the nearest hundredth.
Answers
Answer:
8.95feet
Step-by-step explanation:
The set up is a right angled triangle where;
The camera's horizontal distance from the focus point = 26feet = Adjacent;
The height of the camera above the floor = Opposite = x
Angle of elevation = 19°
According to TOA in trig identity;
Tan theta = opp/adj
Tan 19 = x/26
x = 26tan 19
x = 26(0.3443)
X = 8.95feet
Hence the camera is placed at a height of 8.95feet above the floor

14. x° = 99°
Step-by-step explanation:
The given diagram is the diagram of a kite, therefore, we have;
One Pair of opposite angles are equal
Therefore, ∠x° = 99°
y° = 360 - 2 × 99 - 54 = 108
The base angles are;
(180 - 108)/2 = 36°
Similarly we have;
The side opposite ∠54° = 12 × 2 × cos(36°) ≈ 19.416
a/sin(63°) = 19.416/sin(54°)
a = sin(63°) × 19.416/sin(54°) ≈ 21.38
14. x° = 99°

What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the total number of guest is x;
and, the Total Cost of Hosting a Private Party be y;
here it is given that :
A restaurant charges a $100 setup fee, plus $15 per guest, to host a private party then, this van be shown in linear equation as :
y = 15x + 100
Now, for 45 number of guests that is x = 45, then y will be :
y = 15x + 100
y = 15 x 45 + 100
y = 675 + 100
y = 775 $
Thus, the restaurant charge 775 $ in total for a private party with 45 guests.
