Answer:
brett took 10.8 seconds
Step-by-step explanation:
brett takes 2/3 of the total amount of time to run the forty yard dash
andrew takes 1/3 of the total amount of time to run the forty yard dash
if you divide 16.2 by 3 you get 5.4 which is 1/3 of the total amount of time which is Andrew's time
multiply 5.4 times 2 to get brett's time - 10.8

The amount that could be the price of the second van in the considered case is given by: Option A: $12,987
How to identify the place value of a digit in a number?The place values on left of decimal point start as ones, tens, hundreds, and so on.
The place value on right of decimal point starts from point and goes to right as tenths, hundreths and so on
The tens means multiply by 10
The tenth means tenth part of that digit which is that digit divided by 10
The xth position in left of decimal point in a number from decimal number system has value of \(10^{x-1}\) per unit.
Thus, if the number is 73.46, then the value 7, which is on 2nd position have \(10^{2-1} = 10\) values per unit. Since it is 7, so 7 times 10 = 70 value.
We can write 73.46 = 70 + 3 + 0.4 + 0.06
Firstly, the question is missing options and some part of the orignal question.
The questions says that the price of the second van has a digit 2 which is 10 times the value of the digit 2 in the price of the first van.
The options for second van's price are:
$12,987$15,927$17,257$21,579The price of the first van is $16,257
We use the decimal number system, the place value of 2 is 100th (as there are two digits in the left of 2 (without decimal point) for each unit. 2 is 2 units, so value of 2 in the price of first van is \(2 \times 100 = 200\)
The second van's price has value of 2 10 times more than value of 2 in price of first van.
That means its value is 200 times 10 = 2000
The xth position in left of decimal point in a number from decimal number system has value of \(10^{x-1}\) per unit.
Here \(2000 = 2 \times 10^{4-1}\)
That shows 2 should be on 4th place in the price of the second van.
From the options available, we see that the correct option is $12,987 as there is 2 on the fourth place.
Thus, the amount that could be the price of the second van in the considered case is given by: Option A: $12,987

Explanation: So you have to solve the equation, so it would go like this
y = 2x - 2
y = 2 x 1 -2
y = 0
And x is equal to 1
x is equal to one because we substitute the x in the equation starting from 1 or -1 however you want to go and substitute the x to get what 6. So like you see how I solved the equation using 1 as x you get (1, 0)

All digits in a dropdown number are different, and one of its digits is the average of all its digits. It has at least two digits. For example, 5021 is a dropdown number, but neither 4389 nor 6033 is a dropdown number.
Questions:
1. Find the smallest dropdown number.
2. What are the smallest and largest 4-digit dropdown numbers?
3. How many 3-digit dropdown numbers are there?
4. Is it possible for a pair of consecutive numbers to both be dropdown numbers? If not, explain why not. If it is possible, find the smallest such pair.
Answers
1. Start the search among 2-digit numbers. A dropdown number (DDN) with 2 digits is a number \(ab\) such that
\(\dfrac{a+b}2 = a \implies a + b = 2a \implies b = a\)
or
\(\dfrac{a+b}2 = b \implies a+b = 2b \implies a=b\)
but both of these solutions violate the requirement that the digits are distinct, so there are no 2-digit DDNs.
A 3-digit DDN \(abc\) is such that
\(\dfrac{a+b+c}3 = a \implies a+b+c = 3a \implies b+c = 2a\)
or \(a+c=2b\) if the average is \(b\), or \(a+b=2c\) if the average is \(c\). The smallest possible value for \(a\) is 1 since we require 3 digits. Then \(b+c=2\), and we can pick \(b=0\) and \(c=2\) to get the smallest DDN, 102.
2. In a 4-digit DDN \(abcd\), we have
\(\dfrac{a+b+c+d}4 = a \implies a + b + c + d = 4a \implies b+c+d=3a\)
or \(a+c+d=3b\) or \(a+b+d=3c\) or \(a+b+c=3d\).
We're free to fix \(a=1\) and \(b=0\) to try to get the smallest DDN. This leaves us with \(c+d=3\) or \(c+d=-1\) or \(1+d=3c\) or \(c=3d\).
The first two cases are impossible - the only choices for \(c,d\) such that \(c+d=3\) are 1 and 2, and the sum of two positive integers must be positive. The smallest possible value of \(c\) is 2; this leaves us with \(1+d=6\) or \(2=3d\), but the latter case is impossible because 3 does not divide 2. So \(d=5\), and the smallest 4-digit DDN is 1025.
To find the largest DDN, start with the largest possible values for \(a\) and \(b\). Let \(a=9\) and \(b=8\). Then \(c+d=19\) or \(c+d=15\) or \(17+d=3c\) or \(17+c=3d\). At most, we can have \(c+d=13\) with 7 and 6, so the first two cases are impossible. If we maximize \(c=7\), then either \(17+d=21\implies d=4\) or \(24=3d\implies d=8\) (which we don't want). So the largest 3-digit DDN is 9874.
3. I don't have an analytical solution to this, but using brute force (program) the total count is 112.
4. It is possible; consider 1249 and 1250, with digital averages
\(\dfrac{1+2+4+9}4=4 \text{ and } \dfrac{1+2+5+0}4=2\)
which happens to be the smallest pair. (Also found with brute force.)

Step-by-step explanation: The Screen is a 6 by 8 rectangle. Seeing as it as a rectangle all you have to do is multiply both sides together to get the area.
6x8=48
To find the parameter all you have to do is add all of the sides together. Since the screen is a rectangle both of the opposite sides will be equal. So the one opposite of six will be six and the opposite of eight will be eight. Add them all together and you have your parameter

A cab company charges a $4 boarding rate in addition to its meter which is $1.50 for every mile. Write a linear equation which models this. Use the equation to determine the total fare for a trip that is 2 miles, 3 miles and 5 miles.
Answers
Answer:
2 miles = 7$
3 miles = 8.50$
5 miles = 11.50$
Step-by-step explanation:
1.50$ per mile + 4$ boarding fee
2 miles
1.50 × 2 + 4 = 7
3 miles
1.50 × 3 + 4 = 8.50
5 miles
1.50 × 5 + 4 = 11.50
The linear equation of the question will be $4 + $1.50(x) where x is the number of miles.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
According to the data provided in the question,
The boarding charge of cab company = $4
Additional charge per mile = $1.50
So, the linear equation will be : ($4 + $1.50x)
Here, x represents the number of miles.
The fare for the trip of 2 mile : $4 + $1.50 (2) = 7
The fare for the trip of 3 mile : $4 + $1.50 (3) = 8.5
The fare for the trip of 5 mile : $4 + $1.50 (5) = 10

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.
Answers
Answer:
Beth's class left for the field trip at 7:13 A.M..
Step-by-step explanation:
To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.
The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.
To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.
9:41 A.M. minus 55 minutes is 8:46 A.M..
8:46 A.M. minus 93 minutes is 7:13 A.M..
Therefore, Beth's class left for the field trip at 7:13 A.M..
