Answer:
15.5 seconds.
Step-by-step explanation:
From the time the driver activated the brakes until he stopped, he travelled 76 - 14 = 62 meters.
During this time the car slowed down from 8 m/s to 0 m/s.
Assuming the deceleration was constant during this time we can apply one of the equations of motion for constant acceleration:
s = (u + v)t / 2 where u = initial velocity, v = final velocity, s = distance and t = the time, so:-
62 = (8 + 0)t/ 2
62 = 8t/2
4t = 62
t = 15.5 seconds.
Julie spend $5.62 at the store. Micah spends 5 times as much as Julie. Jeremy spends $6.72 more that Micah. How much money does each person spend?
Answer:
Julie Spends $5.62, Micah spends $28.10 and Jeremy Spends $34.82
Step-by-step explanation:
If Micah spends 5 times as much as Julie, that is $28.10 because 5.62 x 28.10 = 28.10. If Jeremy spends 6.72 more than Micah, you would do 28.10 + 6.72, which is 34.82

What is the slope of the line that passes through the points (-3,3) and (1,-5)
The slope of the line that passes through (–3, 3) and (1, –5) is –2
Solution:
Given slope of the line passes through two points (–3, 3) and (1, –5).
Formula for the slope of the line passes through two points is
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here, [tex]x_1=-3, x_2=1, y_1=3,y_2=-5[/tex]
Substitute these in the slope formula, we get
⇒ [tex]m=\frac{(-5)-3}{1-(-3)}[/tex]
⇒ [tex]m=\frac{-5-3}{1+3}[/tex]
⇒ [tex]m=\frac{-8}{4}[/tex]
⇒ [tex]m=-2[/tex]
Hence, the slope of the line that passes through (–3, 3) and (1, –5) is –2.

an airplane lands at an airport 80 miles west and 30 miles north of where it took off. How far apart are the airports.
Answer:
85.44 miles apart
Step-by-step explanation:
According to the question;
The airplane flew 80 miles west and 30 miles northWe are supposed to determine how far apart are the airports.
The shortest distance will be the displacement from the initial point.We are going to use the Pythagoras theorem;a² + b² = c² , where a and b are the legs of a right angled triangle and c is the hypotenuse.Therefore, in this case; our legs will be 30 miles and 80 miles, so we need to determine the hypotenuse;That is;
c² = 80² + 30²
= 6400 + 900
= 7300
c = √7300
= 85.44
Thus, the airports are 85.44 miles apart

- the line through (3, 7) and (-1, 4) --
Answer:
[tex]y = \frac{3}{4}x + \frac{19}{4}[/tex]
Step-by-step explanation:
We have to get the equation of the straight line through the points (3,7) and (-1,4).
Now, we know that the two-point formula of a straight line passing through the two points [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] is given by
[tex]\frac{y - y_{1} }{y_{1} - y_{2}} = \frac{x - x_{1} }{x_{1} - x_{2}}[/tex].
So, in our case, the equation of the straight line will be
[tex]\frac{y - 7}{7 - 4} = \frac{x - 3}{3 + 1}[/tex]

John is selling tickets to an event. Attendees can either buy a general admission ticket or a VIP ticket. The general admission tickets are $70 and the VIP tickets are $105. If she knows he sold a total of 33 tickets and made $2730, how many of each type did she sell?
Answer:
The number of general admission tickets sold was 21 and the number of VIP tickets sold was 12
Step-by-step explanation:
Let
x ----> the number of general admission tickets sold
y ----> the number of VIP tickets sold
we know that
[tex]x+y=33[/tex] ---> equation A
[tex]70x+105y=2,730[/tex] ----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both lines
using a graphing tool
The solution is the point (21,12)
see the attached figure
therefore
The number of general admission tickets sold was 21 and the number of VIP tickets sold was 12
Final answer:
To solve how many general admission and VIP tickets John sold, a system of equations is formed and solved, revealing that John sold 21 general admission tickets and 12 VIP tickets.
Explanation:
John is selling tickets to an event with two different pricing options, general admission tickets at $70 and VIP tickets at $105. He sold a total of 33 tickets resulting in revenue of $2730. To determine how many of each type of ticket he sold, we will use a system of equations.
Let x represent the number of general admission tickets sold and y represent the number of VIP tickets sold. We can then form the following two equations based on the information provided:
x + y = 33 (equation 1: total number of tickets sold)
70x + 105y = 2730 (equation 2: total revenue from ticket sales)
To solve this system, we can use the method of substitution or elimination. Here, we'll use substitution for simplicity. First, solve equation 1 for x:
x = 33 - y
Substitute this expression for x in equation 2:
70(33 - y) + 105y = 2730
Simplify and solve for y:
2310 - 70y + 105y = 2730
35y = 420
y = 12
Since y = 12, substitute y back into equation 1 to find x:
x = 33 - 12 = 21
Therefore, John sold 21 general admission tickets and 12 VIP tickets.

Divide 20/100
To find two equivalent fractions
Two equivalent fractions for 20/100 are 1/5 and 2/10. These are found by simplifying the fraction 20/100 by dividing by 20 and 10, respectively. Setting up proportions in different contexts often uses the principle that multiplication and division are related through reciprocals.
Explanation:To find two equivalent fractions for 20/100, we can simplify the fraction by dividing the numerator and the denominator by the same number. Since both 20 and 100 are divisible by 20, we can divide them both by 20 to get the first equivalent fraction, which is 1/5. To find a second equivalent fraction, we might choose another common divisor, like 10, which gives us 2/10 as another equivalent fraction to 20/100.
Converting percents to fractions involves writing the percentage as a fraction with a denominator of 100 and then simplifying. For instance, 20% would become 20/100 which simplifies to 1/5. To set up a proportion in other contexts, you could follow examples like setting scales in drawings or units in ratios equal to one another, and in doing so, you're often utilizing the concept that multiplication and division are related through the use of reciprocals.
