You and your family attend a Broadway show in New York City. The show begins at
6:58pm and ends at 9:46pm. How many seconds long is the show?
Answers
From 7:00 to 9:46 we see it passes 2 hours and 46 minutes.
But it started 6:58 . So we add +2 minutes. 46+2 = 48
2 hours and 48 minutes.
But we must find the second form.
1 hours = 60 minutes = 3600 seconds
So, 2 hours = 120 minutes = 7200 seconds.
and 1 minutes = 60 seconds
48 minutes = 60 x 48 = 2880 seconds.
7200 + 2880 = 10080 seconds.
answer: 10,080 seconds
explanation: the time between 6:58pm and 9:46pm is 2 hours and 48 minutes. two hours would convert to 120 minutes. in total, you would get 168 minutes. since there’s sixty seconds in a minute, you get the answer of 10,080 seconds by multiplying 168 by 60

1. Write the interval shown on the number line
below
3 4 5 6 7 8
as an inequality
using set notation
Answers
Answer:
[tex]x\geq 5[/tex]
[tex]\{x\ |\ x \geq 5\}[/tex] OR {5, 6, 7, 8, .....}
Step-by-step explanation:
First of all, let us have a look at the interval shown on the number line and try to understand it properly.
The number line shows positive numbers starting from 3 that means numbers indicated will be positive numbers.
The number highlighted starts from 5 and there is filled circle at 5.
So, 5 is included in the interval.
The arrow is from 5 towards 8 and so on..
That means Numbers greater than or equal to 5 are represented by the interval.
So, writing as an inequality
Let [tex]x[/tex] represents one of the numbers.
Hence, inequality can be written as:
[tex]x\geq 5[/tex]
Using the set notation:
[tex]\{x\ |\ x \geq 5\}[/tex]
OR
{5, 6, 7, 8, .....}

[tex]A' = A + \vec t[/tex]
[tex]A' = (7,3)+(-9,5)[/tex]
[tex]A' = (7-9,3+5)[/tex]
[tex]A'=(-2,8)[/tex]
[tex]B' = B + \vec t[/tex]
[tex]B' = (-8,6)+(-9,5)[/tex]
[tex]B' = (-8-9,-9+5)[/tex]

Q3) If B is directly proportional to A and B = 3 when A = 18, find the value of B when A = 24.
Answers
Answer:
B = 4
Step-by-step explanation:
Given that B is directly proportional to A then the equation relating them is
B = kA ← k is the constant of proportionality
To find k use the condition B = 3 when A = 18 , then
3 = 18k ( divide both sides by 18 )
k = [tex]\frac{3}{18}[/tex] = [tex]\frac{1}{6}[/tex]
B = [tex]\frac{1}{6}[/tex] A ← equation of proportion
When A = 24, then
B = [tex]\frac{1}{6}[/tex] × 24 = 4
3) Taylor's soccer team purchased uniforms and equipment for a total of $912. The equipment costs $612 and the uniforms cost $25 each. How many uniforms did the school purchase?
Answers
Answer: They purchased 12 uniforms
Step-by-step explanation:
If the equipment cost $612 in total and the uniforms cost $25 each and they spent a total for $912 then we could represent it by the equation 25x + 612 = 912 where x is the number of uniforms that the school purchase.
25x + 612 = 912 solve for x by subtracting 612 from both sides
612 612
25x = 300 divide both sides by 25
x = 12

what was the average speed of the whole journey?
Answers
Answer: 107.5
Step-by-step explanation:
120 x 14= 1680
90 x 10= 900
Now you add 1680+900= 2580
Then you divide the distance (2580) between the speed (14+10)

6. Audrey's monthly car payment is $350 and
she needs to save at least $35 each month for
gas. If Audrey is paid $17.50 an hour, write
and solve an inequality to represent the
number of hours she must work in a month to
pay for her car payment and gas.
Answers
Answer:
22 hours
Step-by-step explanation:
For one month, Audrey has to pay $350 for her payment and $35 for gas, meaning that she will need to pay $385 per month.
$350 + $35 = $385
Audrey makes $17.50 an hour. Set up an equality to find the amount of hours she must work to pay for her car payment and gas.
17.50x > 385
(17.50x)/17.50 > 385/17.50
x > 22
Audrey must work at least 22 hours to pay for her car payment and gas.

Step-by-step explanation:
the probability that a civil servant own a car is 1/6,if two civil servants are selected at random.find the probability that
a.each own a car
b.only one owns a car
Answers
Answer:
The data we have is:
the probability that a civil servant own a car is 1/6
Two civil servants are selected at random.
a) The probability that each own a car.
Ok, here we have two events:
Person 1 haves a car.
Person 2 haves a car.
The probability of each of those events is the same, 1/6.
P1 = 1/6
P2 = 1/6
Now, the probability of both events happening at the same time is equal to the product of the individual probabilities.
P = P1*P2 = (1/6)*(1/6) = 1/36.
b) Only one has a car.
Suppose that Person 1 has the car and Person 2 has not a car.
The probability for person 1 is 1/6.
And for person 2, is the negation of having a car:
So if we have prob of having a car = 1/6
Then the probability of not having a car is = 1 - 1/6 = 5/6.
Then we have:
P1 = 1/6
P2 = 5/6.
The joint probability is:
P = P1*P2 = (1/6)*(5/6) = 5/36.
But we also have the case where person 1 does not have a car, and person 2 does have one, then we have a permutation, and the actual probability is two times the obtained above.
P = 2*(5/36) = 10/36

In a math contest of 10 problems, 5 points were given for each correct answer and 2 points were deducted for each incorrect answer. If Nancy answered all 10 problems and scored 29 points, how many correct answers did she have?
Answers
Answer:
Nancy had 7 correct answers.
Step-by-step explanation:
To solve this problem, we can set up a system of equations. Let's assign the variable c to represent the number of correct answers Nancy had and the variable i represent the number of incorrect answers she had.
We know that the total number of answers is 10 because it is given that she answered all 10 problems. This lets us set up the first equation as follows:
c + i = 10
Then, we can set up a second equation using the number of points (29 total). We know that +5 points were added for each correct response (c) and -2 points were added for each incorrect response (i). Our next equation will look like this:
5c - 2i = 29
There are many different strategies one can use to solve systems of equations. In this case, I am going to use combination. This means I am going to add the two equations together. However, first I should multiply our first equation by 2 so that the "I" variable terms cancel out. This is modeled below:
2c + 2i = 20
Now we can add the two equations:
5c + 2c +2i - 2i = 20 +29
Now we can simplify the equation by combining the like terms to get:
7c = 49
Finally, we should divide both sides of the equation by 7 in order to get the variable c by itself on the left side of the equation.
c = 7
Therefore, the correct number of responses Nancy gave was 7.
Hope this helps!

Darrin is hanging 200 feet of Christmas garland on the fencing that encloses his rectangular front yard. The length is 5 feet less than 5 times the width. Find the length and width of the fencing. Give the measurements in decimal form.
Answers
Answer:
Length = 82.5 feet
Width = 17.5 feet
Step-by-step explanation:
The formula for the Perimeter of a rectangle = 2(Length + Width)
= 2L + 2W
We are told in the question that: Darrin is hanging 200 feet of Christmas garland on the fencing that encloses his rectangular front yard
Hence, The perimeter of the rectangular front yard = 200 feet
200 = 2( L + W).........Equation 1
Also, the length is 5 feet less than 5 times the width
L = 5W - 5
Hence,
200= 2(5W - 5 + W)
200 = 2(5W + W - 5)
200 = 2(6W - 5)
200 = 12W - 10
Collect the like terms
200 + 10 = 12W
210 = 12W
W = 210/12
W = 17.5 feet
Substitute 17.5 for W in Equation 1
200 = 2( L + W).........Equation 1
200 = 2( L + 17.5)
200 = 2L + 35
200 - 35 = 2L
2L = 165
L = 165/2
L = 82.5 feet
Therefore, the Length of the rectangular fence = 82.5 feet while the Width of the rectangular fence is 17.5 feet.
