I need a equation written for this pleeeeeaaaassse! The constant of proportionality is 2.
but I need an equation for this, I have an attachment for you to help. g= c is not correct sorry.
Answers
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.
It's similar to saying y = 2x, but we use c in place of x and use g in place of y.

[tex]4\frac{1}{3}[/tex]
Step-by-step explanation:
Apply PEMDAS order of operations:
→ Parentheses
→ Exponents
→ Multiplication
→ Division
→ Addition
→ Subtraction
________________
[tex]\frac{3}{5}+2^2-\frac{2}{5}\left(8-6\right)\div \:3=4\frac{1}{3}[/tex]
1) Parentheses:
[tex]\left(8-6\right)[/tex]
[tex]8-6[/tex]
[tex]=2[/tex]
[tex]\frac{3}{5}+2^2-\frac{2}{5}\times \:2\div \:3[/tex]
2) Exponents:
[tex]2^2[/tex]
[tex]=4[/tex]
[tex]\frac{3}{5}+4-\frac{2}{5}\cdot \:2\div \:3[/tex]
3) Multiplication/Division:
[tex]\frac{2}{5}\times \:2\div \:3[/tex]
[tex]\frac{2}{5}\times \:2[/tex]
Convert to fraction:
[tex]2=\frac{2}{1}[/tex]
[tex]\frac{2}{5}\times \frac{2}{1}[/tex]
Multiply 2 × 2, and 5 × 1:
[tex]=\frac{4}{5}[/tex]
[tex]\frac{4}{5}\div \:3[/tex]
Convert to fraction:
[tex]3=\frac{3}{1}[/tex]
[tex]\frac{4}{5}\div \frac{3}{1}[/tex]
Apply fraction rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]
[tex]\frac{4}{5}\times \frac{1}{3}[/tex]
Multiply 4 × 1 and 5 × 3:
[tex]\frac{4}{15}[/tex]
[tex]\frac{3}{5}+4-\frac{4}{15}[/tex]
4) Addition/ Subtraction:
[tex]\frac{3}{5}+4[/tex]
[tex]=\frac{23}{5}[/tex]
[tex]\frac{23}{5}-\frac{4}{15}[/tex]
[tex]=\frac{13}{3}[/tex]
Finally, Convert fraction to mixed number:
[tex]\frac{13}{3}=4\frac{1}{3}[/tex]

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 nickelsStep-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.

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
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

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]
