Consider the following incomplete deposit ticket where "x" represents an unknown number: a deposit ticket. the amounts deposited were 520 dollars and 15 cents, 57 dollars and 68 cents, 40 dollars and 25 cents. the cash received was 213 dollars and 51 cents. the total deposited is 498 dollars and 1 cent. how much did kay deposit in cash and coins? a. $404.57 b. $213.51 c. $93.44 d. $284.50

Answers

The net amount that was deposited by Kay both cash and coins is $284. 50.

What is the net amount ?

The can be explained as difference between total deposited and the cash received.

This can be expressed as[ total deposit- total cash received]

Since the total deposited = 498 dollars and 1 cent.

This can be converted to dollar as[tex]( $498.01)[/tex]

The amount received is 213 dollars and 51 cents.

This can be converted to dollar as ($213.51)

Therefore, Net amount [tex]= [498.01 - 213.51]=$284.5[/tex]

Solve the following....
[tex]5x+3y=7\\3x-5y=-23[/tex]

Answers

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]

let's solve ~

The given equations are :

[tex]\qquad \tt \dashrightarrow \:5x + 3y = 7 \: \: \: \: \: \: \: \: \: \: \: \: - (1)[/tex]

and

[tex]\qquad \tt \dashrightarrow \:3x - 5y = - 23 \: \: \: \: \: \: - (2)[/tex]

Now, let's multiply equation (1) by 5 and equation (2) by 3 ~

we will get the results as :

[tex]\qquad \tt \dashrightarrow \:25x + 15y = 35 \: \: \: \: - (3)[/tex]

[tex]\qquad \tt \dashrightarrow \:9x - 15y = - 69 \: \: \: - (4)[/tex]

Now, add equation (3) and (4) :

[tex]\qquad \tt \dashrightarrow \:25x + \cancel{ 15y} + 9x - \cancel{15y }= 35 + ( - 69)[/tex]

[tex]\qquad \tt \dashrightarrow \:34x = - 34[/tex]

[tex]\qquad \tt \dashrightarrow \:x = - 1[/tex]

Now, since we got the value of x, let's evaluate y~ by using equation (1) :

[tex]\qquad \tt \dashrightarrow \:5x + 3y = 7[/tex]

[tex]\qquad \tt \dashrightarrow \:5( - 1)+ 3y = 7[/tex]

[tex]\qquad \tt \dashrightarrow \:3y - 5 = 7[/tex]

[tex]\qquad \tt \dashrightarrow \:3y = 12[/tex]

[tex]\qquad \tt \dashrightarrow \:y = 4[/tex]

Hence, value of y is 4

I hope you understood the whole procedure ~

⇢ Explanation :-

Add [tex]\bold{\underline{5y}}[/tex] to both sides.

[tex]\bold{3x \: - \: 5y \: + \: 5y = -23 \: + \: 5y}[/tex]

Simplify

[tex]\sf{3x = -23 \: + \: 5y}[/tex]

Divide both sides by [tex]\bold{\underline{3}}[/tex]

[tex]\bold{\frac{3x}{3} = -\frac{23}{3} \: + \: \frac{5y}{3}}[/tex]

The equation of line p is y+7= – 1/2 (x–5). Line q is parallel to line p and passes through (4,8). What is the equation of line q? Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.

Answers

Answer:

y = -1/2 x + 10.

Step-by-step explanation:

The line q has the same slope (-1/2) as line p as the 2 lines are parallel.

Equation of the line q:

y - 8 = -1/2(x - 4)

y - 8 = -1/2x + 2

y = -1/2 x + 2 + 8

y = -1/2 x + 10.

The expression P(B|C) is an illustration of probability, and the value of P(B|C) is 0.38

How to determine the value of the probability expression?

From the question, we have the following highlights:

n(B and C) = 9

n(C) = 24

The equation to calculate the probability expression is:

P(B|C) = n(B and C)/n(C)

Substitute known values

P(B|C) = 9/24

Evaluate the expression

P(B|C) = 0.38

Hence, the value of P(B|C) is 0.38

find the rule
5. 11
6. 13
8. n
10. 21

Answers

Answer:

n = 17

Step-by-step explanation:

Method 1

The difference between the 5th and 6th terms is 13 - 11 = 2

Therefore, the next term can be found by adding 2 each time.

If we continue with this sequence, we get:

5 = 11

6 = 13

7 = 13 + 2 = 15

8 = 15 + 2 = 17

9 = 17 + 2 = 19

10 = 19 + 2 = 21

So n = 17

-------------------------------------------------------------------------------------

Method 2

Arithmetic sequence

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

where:

[tex]a_n[/tex] is the nth terma is the first termd is the common difference between terms

Given terms of the sequence:

[tex]a_5=11\\a_6=13\\a_8=n\\a_{10}=21[/tex]

The common difference can be found by subtracting one term from the next term:

[tex]d=13-11=2[/tex]

To find a, substitute the found value of d into the equation for one of the given terms:

[tex]\begin{aligned}a_5 =a+(5-1)2 & =11\\ a+8 & =11\\ a & = 3\end{aligned}[/tex]

Therefore, the formula to find the nth term is:

[tex]\implies a_n=3+(n-1)2[/tex]

[tex]\implies a_n=2n+1[/tex]

So, the 8th term is:

[tex]\implies a_8=2(8)+1=17[/tex]

Lets form a equation

(5,11)(6,13)

Slope:-

m=13-11/6-5=2

Equation:-

y-11=2(x-5)

Put x=8

n-11=2(8-5)n-11=2(3)n-11=6n=17

An apartment building contains 100 units. The one-bedroom units rent for $600 per month. When all the units are rented out, the total monthy rent paid by the tenants is $55,275. How many two-bedroom apartments are there?
O 45
O 66
O 55
O 50

Answers

Answer:

Step-by-step explanation:

Let x represent the number of one bedroom units and y represent the number of two bedroom units.

Since the apartment building contains 100 units:

1) x + y = 100

The total monthly rent paid by the tenants is $55,275, so:

2) 495x + 600y = 55275

Solving equation 1 and 2 gives:

x = 45, y = 55

So, there are 55 two-bedroom units in the apartment.

B. (x, y) ⇒ (x, -y)

Step-by-step explanation:

When a point is reflected over the x-axis, it is moved along a vertical line to the same distance on the other side of the x-axis.

The x-coordinate of a point identifies its distance from the y-axis--the vertical line it is on. The y-coordinate identifies its distance from the x-axis. Changing the sign of the y-coordinate moves the point to the same distance on the other side of the x-axis--reflecting it over the x-axis.

The given points ABC and A'B'C' all match the pattern ...

(x, y) ⇒ (x, -y)

A(-1, 7) ⇒ A'(-1, -7)

B(6, 5) ⇒ B'(6, -5)

C(-2, 2) ⇒ C'(-2, -2)

so the image points represent a reflection over the x-axis of the original points.
