Sofia has 25 coins in nickels and dimes in her pocket for a total of $1.65. How many of each type of coin does she have? First complete the equations below, where N stands for nickels and D stands for dimes. [?]N + [ ]D = 1.65; N + D
Answer:
Step-by-step explanation:
Let n represent nickels & d dimes
given: n + d = 25 #1 (number of coins)
given: .05n + .10d = 1.65 #2 (amount in dollars)
n = 25 - d #3 (rewrite of #1)
.05(25 -d) + .10d = 1.65 (substitute #3 in #2)
1.25 - .05d + .10d = 1.65 (multiply out the left side)
.05d = .40 (collection of like terms)
d = 8 (divided both sides by.05)
n + 8 = 25 (substitute answer for d in #1)
n = 17 (subtract both sides by 8)
There are 8 dimes and 17 nickels.
Check:
17(.05) + 8(.10) = 1.65 (answers in #2)
.85 + .80 = 1.65 (multiply out the left side)
1.65 = 1.65 ✔️ QED
Answer: There are 8 dimes and 17 nickels.
Step-by-step explanation: 0.05N+.10D=1.65; N+D=25

How many permutations of a 7-digit phone number exist if any number 0-9 may be used but repetition is not allowed?
Answer:
There are 604,800 possible permutations.
Step-by-step explanation:
The order in which the digits are chosen is important, which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
7 digits from a set of 10(10 digits to 0-9). So
[tex]P_{(10,7)} = \frac{10!}{(10-7)!} = 604800[/tex]
There are 604,800 possible permutations.
Answer:
10!/3!
Step-by-step explanation:
i just took a test and got it right
Because repetition is not allowed, and there are 10 initial options for the 7 decisions that need to be made, we use the formula
n!/(n-r)! = 10!/(10-7)! = 10!/3!
WILL GIVE BRAINLIEST anitas and caseys bills do not vary from month to month. anita pays 80 more than casey does each month. over the course of 4 months,their combined bill is 1,520. write the system of equations that describes this situation and solve it to find the montly payments for anita and casey.
Answer:
1520/4=380 per month
Step-by-step explanation:
The monthly payments for Anita and Casey are 230 and 150.
What is equation?"An equation is a formula that expresses the equality of two expressions consisting of variables and/or numbers, by connecting them with the equals sign =."
Assume
Monthly payments for Anita = x
Monthly payments for Casey = y
We have
Anita pays 80 more than Casey does each month.
We can write the equation
x = y + 80
x - y = 80 ...........................(1)
Over the course of 4 months, their combined bill is 1,520.
We can write the equation
4x + 4y = 1520...................(2)
Solving equations (1) and (2) by substituting equation x = y + 80 in equation (2)
⇒4x + 4y = 1520
⇒4(y + 80) + 4y = 1520
⇒4y + 320 + 4y = 1520
⇒8y = 1520-320
⇒8y = 1200
⇒y = [tex]\frac{1200}{8}[/tex]
⇒y = 150
Substitute y = 150 in equation (1)
⇒x - y = 80
⇒x - 150 = 80
⇒x = 80+150
⇒x = 230
Hence, the monthly payments for Anita and Casey are 230 and 150.

In TRIANGLE ABC, what is the value of x?
Answer:[tex]70^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle BAC=112^{\circ}\\\angle BCM=(2x+12)^{\circ}\\\angle ABL=2x^{\circ}[/tex]
[tex]\angle ACB[/tex] is given by [tex]180^{\circ}-\angle BCM[/tex] as the angle around a straight line is [tex]180^{\circ}[/tex]
[tex]\therefore \angle BCA=180^{\circ}-2x^{\circ}-12^{\circ}\\\angle BCA=(168-2x)^{\circ}[/tex]
Also, using exterior angle property. We can write
[tex]\angle BCA+\angle BAC=\angle ABL[/tex]
Insert the values
[tex]\Rightarrow 168^{\circ}-2x^{\circ}+112^{\circ}=2x^{\circ}\\\Rightarrow 280=4x^{\circ}\\\Rightarrow x=70^{\circ}[/tex]

-5X-3Y=-7 FIND 3 POINTS THAT SOLVE THE EQUATION
Answer:
(0, 7/3), (1, 2/3), (2, -1).
Step-by-step explanation:
Input 3 x coordinates into the equation and find the y. 0, 1, and 2 will do.
-5x - 3y = -7
Substitute variable.
-5(0) - 3y = -7
Remove the term multiplied by 0.
-3y = -7
Divide by -3.
y = -7/-3
-a/-b = a/b.
y = 7/3
This makes the coordinate (0, 7/3)
-5x - 3y = -7
Substitute variable.
-5(1) - 3y = -7
Multiply.
-5 - 3y = -7
Add 5 to both sides.
-3y = -2
Divide by -3.
y = -2/-3
-a/-b = a/b.
y = 2/3.
This makes the coordinate (1, 2/3)
-5x - 3y = -7
Substitute variable.
-5(2) - 3y = -7
Multiply.
-10 - 3y = -7
Add 10 to both sides.
-3y = 3
Divide by -3.
y = 3/-3
-a/a = -1.
y = -1.
This makes the coordinate (2, -1).

Answer:
b = 2a - 1
Step-by-step explanation:
a = 1 , b = 2 x 1 - 1 = 2 - 1 = 1
a = 2 , b = 2 x 2 - 1 = 4 - 1 = 3
a = 3, b = 2 x 3 - 1 = 6 - 1 = 5
a = 4, b = 2 x 4 - 1 = 8 - 1 = 7
Answer:
b = 2a - 1
Step-by-step explanation:
We can see the pattern:
1 = 1 + 0 = 1 + 1 - 1
1 = 1 - 1
3 = 2 + 1 = 2 + 2 - 1
3 = 2 + 2 - 1
5 = 3 + 2 = 3 + 3 - 1
5 = 3 + 3 - 1
7 = 4 + 3 = 4 + 4 - 1
7 = 4 + 4 - 1

What is Polygons?Polygons are closed figures which has at least three set of line segments joined together.
The polygon with least number of sides is triangle.
7) It is a polygon with 4 sides (quadrilateral)
Sum of the interior angles of a quadrilateral = 360°
45° + 65° + 95° + x = 360°
x = 360° - (45° + 65° + 95°)
x = 155°
8) Sum of the interior angles of a polygon = (n - 2)180°, where n is the number of sides.
There are 6 sides.
Sum of the interior angles = (6 - 2)180° = 720°
x + 140 + 130 + 120 + 90 + 150 = 720
x = 90°
9) n = 5
Sum of the interior angles = (5 - 2) 180° = 540°
2x + 90 + 100 + 70 = 540
2x = 280
x = 140°
10) Sum of the exterior angles of a polygon is 360°.
4x + x + 98 + 162 = 360
5x = 100
x = 20°
Hence the values of x are found.

The population of a town is increasing at a rate of 6.2% per year. The city council believes they will have to add another elementary school when the population reaches 100,000. If there are currently 76,000 people living in the town, how long do they have before the new school will be needed?
Answer:
The correct solution is "4.6".
Step-by-step explanation:
Given:
Interest rate,
r = 6.2%
or,
= 0.062
Amount,
A = 100000
Principle,
P = 76000
As we know,
⇒ [tex]A=P(1+\frac{r}{100} )^n[/tex]
On substituting the values, we get
⇒ [tex]100000=76000(1+\frac{6.2}{100} )^n[/tex]
⇒ [tex](1+0.062)^n=\frac{100}{76}[/tex]
On taking log both sides, we get
⇒ [tex]n \ log_e(1.062)=log_e(\frac{100}{76} )[/tex]
⇒ [tex]n=\frac{ln(\frac{100}{76} )}{ln(1.062)}[/tex]
By putting the values of log, we get
⇒ [tex]=4.5622[/tex]
or,
⇒ [tex]=4.6[/tex]
Each week Thomas will double the amount of money in his bank. What type of function is represented by this situation
Answer:
An exponential growth.
Step-by-step explanation:
We know that each week, Thomas will double the amount of money in his bank.
Let's assume that in week 0, he has an amount A of money in his bank.
After one week, in week number 1 (w = 1), the amount of money is doubled, so if we define the function M(w) as the amount of money as a function of the number of weeks, we will have:
M(1) = 2*A
After another week, in w = 2, the amount of money is doubled again, so here we have:
M(2) = 2*(M(1)) = 2*(2*A) = A*2^2
After another week, at w = 3, the amount of money is doubled again:
M(3) = 2*(M(2)) = 2*(A*2^2) = A*2^3
We already can see the pattern here, we can expect that for the week w, the amount of money in the account is given by:
M(w) = A*2^w
This is an exponential equation (an exponential growth to be more specific), so the type of function that is represented by this situation is an exponential growth.
