The book store earned x dollars in profit. Last week, the total profit
increased by 5%. Which expression represents the book store's total
increase in profit?

Answers

Answer 1

Answer:

x + 0.05x

Step-by-step explanation:

Given

Earnings earned by the bookstore = x

percentage increase = 5%

Increment = 5% of x

Increment = 0.05x

book store's total  increase in profit = Original earning + increment

book store's total  increase in profit x + 0.05x

Hence the expression that represents the book store's total  increase in profit is x + 0.05x

True or False: The Commutative Property of Addition states that for all expressions a and b , ab = ba.

Answers

According to the Commutative Property of Addition, ab = ba for all expressions a and b: FALSE

What is the Commutative Property of Addition?According to the commutative property of addition, altering the order of addends has no impact on the sum. Here's an illustration: 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+4. The addition and multiplication arithmetic operations are covered by the commutative property. This implies that the outcome of adding or multiplying two numbers remains unchanged if the order or position of the numbers is changed. For instance, 4 + 5 equals 9, and 5 + 4 equals 9.

According to the Commutative Property of Addition, rearranging the addends has no impact on the sum.

a+b=b+a

Therefore, the statement "according to the Commutative Property of Addition, ab = ba for all expressions a and b" is FALSE

Solve the following system of equations. x + y + 8z = 16
2x + 7z = 19
4x - 4y + 4z = 4

a. x = 1,y = 2,z = 2
b. x= 2,y = 2,z = 1
c. x = 6,y = 2,z = 1
d. x = 13,y = 11,z = -1​

Answers

By substitution, we will see that the solution of the system is:

x = 13, y = 11, z = -1

The correct option is D.

How to solve the system of equations?

Here we have a system of 3 equations:

x + y + 8z = 16

2x + 7z = 19

4x - 4y + 4z = 4

I will solve it by substitution, first, let's simplify the equations. Here we can divide the third equation by 4 so we remove all the common factors, then the system becomes:

x + y + 8z = 16

2x + 7z = 19

x - y + z = 1

Now, I will isolate x on the second equation:

x = (19 - 7z)/2 = (19/2) - (7/2)*z = 9.5 - 3.5*z

Now we can replace that on the other two equations:

(9.5 - 3.5*z) + y + 8z = 16

(9.5 - 3.5*z) - y + z = 1

Rewriting the system we get:

y + 4.5z = 6.5

-y - 2.5z = -8.5

Now we can isolate y on the first equation:

y = 6.5 - 4.5z

Replacing that on the other equation we get:

-(  6.5 - 4.5z) - 2.5z = -8.5

-6.5 + 4.5z - 2.5z = -8.5

2z = -8.5 + 6.5 = -2

z = -2/2 = -1

Then the value of y is:

y = 6.5 - 4.5z = 6.5 - 4.5*(-1) = 11

And the value of x is:

x = 9.5 - 3.5*z = 9.5 - 3.5*(-1) = 13

So the solution of the system is:

x = 13, y = 11, z = -1

The correct option is D.

Using a system of equations, it is found that Stefan won 7 games.

In our system, we have that:

x is the number of games Marion won.y is the number of games Stefan won.

Marion won five times the difference between the number of games Stefan won and the number four, hence:

[tex]x = 5(y - 4)[/tex]

Marion won 15 games, hence [tex]x = 15[/tex], and:

Graphically solve a system of equations in order to determine the number of cookies, x,x, and the number of brownies, y,y, that Jace bought.

Answers

Answer:

(9, 18) (3, 6) Plz correct me if wrong

Step-by-step explanation:

Jace bought 4 cookies and 2 brownies from the bakery.

Let x represent the number of cookies and y represent the number of brownies.

Since he bought $9 worth of cookies and brownies. Each cookie costs $0.75 and each brownie costs $3. hence:

0.75x + 3y = 9      (1)

Also, he bought twice as many cookies as brownies, hence:

x = 2y

x - 2y = 0     (2)

Solving equation 1 and 2 simultaneously gives x = 4, y = 2

Hence Jace bought 4 cookies and 2 brownies from the bakery.

B. 4.6
C. 7.05
D. -1.88

Answers

B.4.6
I divided 276/60 and got b

The Z-score for a weekly rental is 2.45 which is the correct answer would be option (B).

What is Z -score?

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

Given the average cost to rent a car for a week is $276

And the standard deviation is $60

To determine the Z-score for a weekly rental of $423.00

Here,

ц = 276

σ = 60

X = 423

⇒ z-score = (X-ц )/σ

Substitute the values,

⇒ z-score =  (423 - 276)/60

⇒ z-score = 147/60

⇒ z-score = 2.45

Hence, the z-score for a weekly rental is 2.45.

Step-by-step explanation:

The sampling rate: [tex](f_s) = 52,500 \ \frac{samples}{sec}[/tex]

In point a:

The sample signal frequency = f  

They recognize that the id [tex]\geq[/tex] 2f sampling frequency could be returned to its original signal unless the aliase effect is detected elsewhere,  Yet under percentage =18%

[tex]\ sampling \ rate = 2 \times 1.18 \times f[/tex]

[tex]f_a =22,246 \times 1.1[/tex]

    [tex]= 24,470.6\\\\=24,471[/tex]

[tex]\ sampling \ rate= x \times 2 \times 24,2471 \\[/tex]
