sara ordered 2 eggs, a slice of bacon, and a glass of orange juice for breakfast. the sales tax for the order was $0.48. she paid for her breakfast with a $10 bill.
one egg = $1.69
slice of bacon = $1.49
glass of orange juice = $1.09
how much change should sara receive from the $10 bill?
Answer:
She should receive $3.56 from paying with a $10 bill
Step-by-step explanation:
The total cost of all her items including sales tax is
$6.44
You have to deduct this total cost from what she paid with.
$10.00 - $6.44 = $3.56
Therefore,
Sara should receive $3.56 from paying with a $10 bill.
Answer: $3.56
Step by step explanation:
1. Figure out how much the eggs cost. (1.69×2=3.38)
2. Add the price of the eggs, bacon, O.J., and sales tax together. (3.38+1.49+1.09+0.48=6.44)
3. Subtract the total ($6.44) by the amount you paid ($10). (10-6.44=3.56)

The revenue from selling x tickets is r(x) = 10x. The cost for buying x tickets is c(x) = 8x + 40. The profit from selling x tickets is p(x) = r(x) – c(x).9. What is p(x)? *
Answer:
p(x)=2x-40
Step-by-step explanation:
Substitute the variables
p(x)=10x-(8x+40)
p(x)= 10x-8x-40
p(x)=2x-40
Answer:
p(X) = r(X) - c(X).9
⇔ p(X) = 10x - (8x+ 40).9
⇔ p(X) = 10x - 72x - 360
⇔ p(X) = -62x - 360

A manager of the credit department for an oil company would like to determine whether the mean monthly balance of credit card holders is equal to $75. An auditor selects a random sample of 100 accounts and finds that the mean owed is $83.40 with a sample standard deviation of $23.65. If you were to conduct a test to determine whether the auditor should conclude that there is evidence that the mean balance is different from $75, which test would you use? a) Z-test of a population mean b) Z-test of a population proportion c) t-test of population mean d) t-test of a population proportion
Answer:
c) t-test of population mean
Explanation:
The t-test statistic is used in hypothesis testing. Here we would use a one sample t test to test our hypothesis. The one sample t test measures the statistical difference between the hypothesized mean and the sample mean. In a one sample t test or single sample t test, a test variable is measured against a test value.
Example we compare our test variable to the hypothesized mean value $75 above.
The t test is used instead of z score when standard deviation is unknown.
Using the t test, we either accept or reject the null hypothesis given alternative hypothesis.

3x+7y=27
-3x+y=21
Answer:
x = -5
y = 6
Step-by-step explanation:
3x + 7y = 27 --------------(I)
-3x + y = 21 -----------(II)
Add equation (I) & (II) and so x will be eliminated and we can find the value of y.
(I) 3x + 7y = 27
(II) -3x + y = 21 {add}
8y = 48
y = 48/8
y = 6
Plugin y = 6 in equation (I)
3x +7*6 = 27
3x + 42 = 27
3x = 27 - 42
3x = -15
x = -15/3
x = -5

Step-by-step explanation:
Identify the two factors that were multiplied together to form the array of tiles. Then identify the product of the two factors. Use the variable x in your expressions.
Answer:
[tex]Terms: 3\ and\ x + 2[/tex]
[tex]Product = 3x + 6[/tex]
Step-by-step explanation:
See attachment for complete question.
From the attachment, there are 3 columns and 3 rows
The 3 columns represent the first factor
To get the second factor, we have to analyze the 3 rows in the attachment.
Notice that the first row is bigger than the other two rows.
This big row will be represented with variable x
Notice that the boxes in second row are smaller than the first row and the + sign is written on each of the boxes.
This is represented with + 1
Also, notice that the boxes in third row are smaller than the first row and the + sign is written on each of the boxes.
This is also represented with + 1
Hence, the expression for the rows is x + 1 + 1 = x + 2
The product is then calculated as:
[tex]Product = 3 * (x + 2)[/tex]
[tex]Product = 3 * x + 3*2[/tex]
[tex]Product = 3x + 6[/tex]

Step-by-step explanation:
Step 1: Define
8y + 11 = 6y + 11
Step 2: Solve for y
Subtract 6y on both sides: 2y + 11 = 11Subtract 11 on both sides: 2y = 0Divide 2 on both sides: y = 0Answer:
Step-by-step explanation:
8y+11=6y+11
we have the same number in both sides, they will cancel out
8y-6y=0
2y=0
y=0 is the only solution
-4.8 (6.3x-4.18)=-58.56 what is x?
Answer:
x = 2.825
Step-by-step explanation:
-4.3(6.3x + -4.18) = -58.56
-4.3(-4.18 + 6.3x) = -58.56
(-4.18 * -4.3 + 6.3x * -4.3) = -58.56
(17.974 + -27.09x) = -58.56
17.974 + -27.09x = -58.56
17.974 + -17.974 + -27.09x = -58.56 + -17.974
0.000 + -27.09x = -58.56 + -17.974
-27.09x = -58.56 + -17.974
-27.09x = -76.534
x = 2.825175341
Which lines have a y-intercept of 5? Check all that apply.
A: y=5x-1
B: 4x-8y=40
C: x-y=5
D: x-3y=15
E: 2x-y=10
F: 6x+4y=20
Answer:
F: 6x+4y=20
Step-by-step explanation:
Only line representing the equation 6x+4y=20 has y-intercept of 5.
The line that has the y-intercept = 5 is 6x + 4y = 20
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
The standard slope intercept form:
y = mx + b
Comparing the options A,C,D and E with standard form and none of the options have b = 5.
So these options are out.
Now the options B,
Simplify, y = x/2 - 5
Compare with slope intercept form, and this equation also does not have
the y intercept as 5.
Now option F;
simplify, 6x + 4y = 20
y = -3x/2 + 5
Comparing with standard form,
And b= 5
Therefore, The line that has the y-intercept = 5 is 6x + 4y = 20

The seniors on the student council bought a total of 36 plants to use in landscaping the front of the school. They bought some azaleas that cost $6
each and some lilles that cost $5 each. They spent a total of $196 on these plants. How many azaleas did the students buy?
Answer:
The students bought 16 azaleas plants.
Step-by-step explanation:
Given that:
Total plants bought by student council = 36
Cost of each azaleas plant = $6
Cost of each lily plant = $5
Total amount spent = $196
Let,
x be the number of azaleas
y be the number of lilies
x+y = 36 Eqn 1
6x+5y=196 Eqn 2
Multiplying Eqn 1 by 6
6(x+y=36)
6x+6y=216 Eqn 3
Subtracting Eqn 2 from Eqn 3
(6x+6y)-(6x+5y)=216-196
6x+6y-6x-5y=20
y=20
Putting y=20 in Eqn 1
x+20=36
x=36-20
x=16
Hence,
The students bought 16 azaleas plants.
