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
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.

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.
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.

Solve x2−4x−12=0 by completing the square. A x=−2 B x=−6 or x=2 C x=−2 or x=6 D x=−6
Answer:
B x=-6
x=2
Step-by-step explanation:
Let f(x)=2x-1,g(x)=3x and h(x)=x^2+1 evaluate h(-2)-f(-2)
h (-2) = (-2)^2 + 1 = 5
f (-2) = 2(-2) - 1 = -5
5 - (-5) = 10.

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.
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
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

Answer:
[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]
