Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode(!), she drove at a constant speed to get to the safe zone that was 160 meters away. After 3 seconds of driving, she was 85 meters away from the safe zone.
Let y represent the distance (in meters) from the safe zone after x seconds.
Which of the following could be a graph of the relationship?
Answers
The graph that could represent the relationship between distance and time is: Graph C.
How to Interpret the Graph of a Relationship?A graph is usually plotted to have the independent variable on the x-axis and the dependent variable on the y-axis. For example, tin the scenario given, distance is plotted on the y-axis, while time is plotted on the x-axis.
The slope of a graph declines if the initial value decreases or if the slope value is negative and reduces.
In this scenario given, the starting value/initial value is 160 meters. After 3 seconds of driving, the initial value/starting value decreases to 85 meters.
This implies that the slope of the graph is declining from left to right. Therefore, the graph that could represent the relationship between distance and time is: Graph C.

15 total kids were at the park. 6 of them were girls. What % of the kids were girls?
Answers
Answer:
40%
Step-by-step explanation:
6/15 = 0.4
0.4 * 100 = 40%
Answer:
40%
Step-by-step explanation:
Since there are 15 total kids and 6 of them are girls, we can write this question as the fraction 6/15.
6/15 is 0.4 and to get the percent you would multiply by 100%.
Therefore the answer is 40%

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?
Answers
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).

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.

[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 -

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.

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

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)

What is 25% of 80? in table form
Answers
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

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.
