Kevin and Randy Muise have a jar containing 68 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $8.00. How many of each
type of coin do they have?
The jar contains
quarters

Answers

9514 1404 393

Answer:

23 quarters45 nickels

Step-by-step explanation:

Let q represent the number of quarters. Then the number of nickels is 68-q, and the number of cents in the jar is ...

  25q +5(68 -q) = 800

  20q +340 = 800 . . . . simplify

  20q = 460 . . . . . . . . subtract 340

  q = 23 . . . . . . . . . . . divide by 20; this is the number of quarters

  68-q = 45 . . . . . . . find the number of nickels

The jar contains 23 quarters and 45 nickels.

The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour. If
the depth after 6 hours of draining is 8 feet then write an equation for the water depth, d, as a function of the
amount of time it's been draining, t, in hours.

Answers

The linear function for the depth of water after t hours is given by:

[tex]d(t) = 17 - 1.5t[/tex]

The format of a linear function is given as follows:

[tex]d(t) = d(0) - at[/tex]

In which:

d(0) is the y-intercept, which is the initial value.a is the slope, which is the rate of change.

The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour, which means that [tex]a = -1.75[/tex], thus:

[tex]d(t) = d(0) - 1.5t[/tex]

The depth after 6 hours of draining is 8 feet, which means that when [tex]t = 6, d(t) = 8[/tex]. This is used to find d(0).

[tex]d(t) = d(0) - 1.5t[/tex]

[tex]8 = d(0) - 1.5(6)[/tex]

[tex]d(0) = 17[/tex]

Then

[tex]d(t) = 17 - 1.5t[/tex]

find the sum of all possible four digit numbers that can be formed using the digits 2,4,5,6,7 and 8 with no repeated digits

Answers

1+1
2+2
5+0
3+3
6+2-1
4+4

Answer:

2133120

Step-by-step explanation:

using 6 given digits, lets create a 4 digit number:

to choose the first number, you have 6 options. to choose the second number we have 5 options left. for the third number we have 4 options left. and for the fourth number, we have 3 options left.

6*5*4*3 = 360

with no repeats, 360 numbers can be formed.

this means that each number will occur 60 times each (360/6 digits)

so to find the sum:

60*(2+4+5+6+7+8) = 1920

but, we have one more thing:

In the thousands place, our sum of digits is multiplied by 1000; in the 100’s place, by 100; in the ten’s place, by 10; and in the one’s place, by 1. so:

1920(1000+100+10+1) = 1920*1111 = 2133120

It sounds like your teacher wants g = 2c as the answer. The constant of proportionality simply tells us what to multiply the input variable by, to get the output variable.
