ivolga24 [154]3 years ago
4 0

Answer:

Step-by-step explanation:

An exponential equation has the form

y=ar^x where y=final value, a=initial value, r=rate, and x=time, in this case

y=28000(0.73^x)

So the initial value is 28000 and r=0.73. Since 0.73 is less than one this is an exponential decay representing a 27% loss per year. So B and F are correct.

Which of the following reasons could be used to conclude that the lines are parallel based on the given information?
rewona [7]

We have been given three statements. From those statements, we have to pick the statement that can conclude that that two lines are parallel.


Statement 1:

If right angles are formed, then lines are parallel.

This is not valid because if the angle formed is right angle then lines forming right angle will be perpendicular.


Statement 2:

If two lines are perpendicular to another line, then they are parallel.

This is valid because the line on which other two lines are perpendicular will work as transversal and the alternet interior angles will be equal. Hence the two perpendicular lines on given line will be parallel to each other.


Statement 3:

If alternate interior angles are equal, then lines are parallel.

This is valid as explained above.


Hence final answer are statement 2 and statement 3 both.

a box of marbles can be shared equally among 6,7,or 8 students with 4 marbles left over each time.what is the least possible num
Vlad1618 [11]
If there are 4 marbles left over each time, then we can forget about them for now.

So the question is, what is the smallest number than can be divided into 6,7 and 8?

the numbers have only one non-1 divisor in common: both 6 and 8 are divisible by 3.

so for our purposes we can "delete" one 2 and ask:


what is the smallest number than can be divided into 3,7 and 8 ?

There are no more divisors in common, so we just have to multiply them: 3*7*8=21*8=168


and the 4 marbles "extra"? We add them to this sum.


the the smallest possible number in the box is 168+4=172.

In the group of scores 6, 12, 13, 13, 16, and 18, it can be said of the mean, the median, and the mode that _____.
Vera_Pavlovna [14]

Mean = (6 + 12 + 13 + 13 + 16 + 18)/ 2 = 78/2 = 13

Mode = 13

Median = 0

Mean and mode are equal = 13

There is no median.

The cost of 4 belts and 5 ties is $247. Each time costs 3 times as much as a belt. What us the total cost of 1 belt and 1 tie
Makovka662 [10]

Answer:

The total cost of 1 belt and 1 tie is $13 and $39 respectively.

Step-by-step explanation:

Given that,

The cost of 4 belts and 5 ties is $247.

Each tie costs 3 times as much as a belt.

Let the cost of a belt is x and that of a tie is y.

ATQ,

4x + 5y = 247 ...(1)

y = 3x ....(2)

Put the value of y from equation (2) in equation (1)

4x + 5(3x) = 247

4x + 15x = 247

19x = 247

x = 13

Put the value in equation (2)

y = 3x

= 3(13)

= 39

So, the total cost of 1 belt and 1 tie is $13 and $39 respectively.

melamori03 [73]

Answer

8 is not greater than 10

Step-by-step explanation:

2x>10

2(4)>10

8<10

x=4 can not be the solution to this equation because 8 is less than 10
