Answer:
6.50w
Step-by-step explanation:
Given that :
Weight ________ Cost ($)
1 ______________6.50
2 _____________ 13.00
3 _____________ 19.50
Cost of package that weighs w pounds
If one pound = 6.50
2 pounds = 13.0
Then, the cost per pound = $6.50
Hence, cost of package that weighs w pounds will be ;
$6.50 * w = $6.50w
What is 25% of 80? in table form
Answer:
20
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 80=100%.
Step 4: Similarly, x=25%.
Step 5: This results in a pair of simple equations:
80=100% (1).
x=25%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
{80} = {100%} {25%}
Step 7: Again, the reciprocal of both sides give
{80}= {25} {100}
x=20
Therefore, 25% of 80 is 20

What does the point (1, 3) represent on the graph?
image
A.
It shows for every 1 item produced the revenue is $3.
B.
It shows that for every 3 items produced the revenue is $1.
C.
It shows that for every 300 items produced the revenue is $100.
D.
It shows that the revenue is a constant rate of $1.
Answer:
A
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.
I hope this helps!!

We can say that any of the two given conditions are true -
It shows for every 1 item produced the revenue is $3.It shows that the revenue is a constant rate of $1.What is the general equation of a Straight line?The general equation of a straight line is -y = mx + c
[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 -
It shows for every 1 item produced the revenue is $3.It shows that the revenue is a constant rate of $1.To solve more questions on straight line, visit the link below-

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.
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)

Answer:
13. ∠x° = 99°
y° = 108
a ≈ 21.38
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°

The midpoint of \overline{\text{AB}}
AB
is M(-2, 5)M(−2,5). If the coordinates of AA are (1, 7)(1,7), what are the coordinates of BB?
The coordinates of the B is obtained as (-5, 3).
What is referred as coordinates?Coordinates are 2 numbers (Cartesian coordinates) or a letter and a number that point to a specific point on a grid known as a coordinate plane.
A coordinate plane does have four quadrants as well as two axes: x (horizontal) and y (vertical) (vertical). The point where the two axes intersect is known as the origin, and its coordinates are (0, 0).Coordinates are composed as (x, y), which means the x axis point comes first, accompanied by the y axis point.Now, as per the given question;
The coordinates of A is given as (1, 7).
The coordinates of mid point M is given as (-2, 5).
The coordinates are listed in pairs, with the x value at the top.
The shift in the x location is as follows:
1 - (-2) = 3
The change in y position is as follows:
7 - 5 = 2
Because the midpoint is half - way between B and A, the change will remain constant, so x is;
- 2 - 3 = -5
And for is;
5 - 2 = 3
Therefore, the values of the coordinates of B is found as (-5, 3).

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?
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.
