Select the three statements that are true.
The amount the customer paid, in dollars, for the chocolate in the bag is 9x.
O The amount the customer paid, in dollars, for the chocolate in the bag is 11y.
The total weight of the bag of chocolate and almonds is 9x + 11y.
The total weight of the bag of chocolate and almonds is x + y.
The cost per pound of the chocolate is $11.
The cost per pound of the almonds is $11.
Answers
Answer:
*The amount the customer paid, in dollars, for the chocolate in the bag is 9x.
*The total weight of the bag of chocolate and almonds is x + y.
*The cost per pound of the almonds is $11.
Step-by-step explanation:
A customer paid 9x + 11y dollars for a bag that contains x pounds of chocolate and y pounds of almonds.
From the above questions, we know that:
The weight of Chocolate = x pounds
The weight of Almonds = y pounds
The cost per Chocolate = $9
The cost per Almonds = $11
Therefore, the three statements that are true are:
* The amount the customer paid, in dollars, for the chocolate in the bag is 9x.
* The total weight of the bag of chocolate and almonds is x + y.
*The cost per pound of the almonds is $11.

Answer:
y = 7x + 36
Step-by-step explanation: Slope intercept form is y = mx + b where your slope is m, your b is the y-intercept, and x and y are your plot points. To solve this you just plug in the numbers. We already know the slope is 7 so we have our m, now we plug in the coordinate (-5, 1) with -5 as x and 1 as y. Plug them in and now you have the equation 1 = 7(-5) + b. You want to solve for b. So you end up getting b= 36. Now you have your y intercept so your final equation is y = 7x + 36. Hope this helped!!
Maxine spent 15 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 120% more time doing homework this week. Is she correct? Show your work to justify your decision.
Answers
Answer:
Yes
Explanation: 120 % = 1.2
If Maxine is correct, then she spent 1.2
times the hours she did homework than last week.
15 ⋅ 1.2 = 18.0 = 18
15 hours ⋅ 1.2 = 18.0 hours = 18 hours
This means that Maxine is correct.

Answer: 32768 or [tex]8^5[/tex].
Step-by-step explanation:
[tex]8^7[/tex]= 8x8x8x8x8x8x8 = 2097152
[tex]8^2[/tex]= 8x8 = 64
Dividing Exponents
When you divide exponents with the same base. You subtract. So in this case, you subtract 7 by 2, (being exponents). The same base is 8. So your subtracting [tex]8^7[/tex] by [tex]8^2[/tex]. Which will get you [tex]8^5[/tex].
Dividing Whole Numbers.
You are going to divide whole numbers. Its pretty self explanatory but I will do the math for you anyways.
64 goes into 2097152, 32768 times. Or we can say,
2097152 divided by 64 = 32768.
So the answer is 32768, or [tex]8^5[/tex].

Denise has $4.25 and needs to buy school supplies. She has a package of pencils that costs $1.75, a notebook that costs $1 and some erasers (x) that costs $0.25 each. At most, how many erasers can denise buy?
Answers
Answer:
6 erasers
Step-by-step explanation:
The pencils and the notebook together cost $2.75, from there you can calculate how many erasers.
1 eraser would bring the total to $3, therefore Denise can buy $1.25 more of erasers which is 5. 3 + 1.25 is $4.25. therefore Denise can buy 6 erasers
Answer:
he can buy 6 erasers
Step-by-step explanation:
because if you add 1.75 plus one and add 0.25 ....6 times it will equal 4.25 i hope this was helpful

Use the figure to find the measures of the numbered angles. ∠5 = ∠6 =
Answers
Answer:
∠ 5 = 49°, ∠ 6 = 131°
Step-by-step explanation:
∠ 5 and 49° are corresponding angles and are congruent, then
∠ 5 = 49°
∠ 5 and ∠ 6 are adjacent angles and are supplementary, sum to 180° , that is
∠ 6 + ∠ 5 = 180°
∠ 6 + 49° = 180° ( subtract 49° from both sides )
∠ 6 = 131°

Answers
Need help please not understanding
Answers
Answer:
The value of ∠4 is 45° .
Step-by-step explanation:
Given that , ∠4 = x + 30 ° & ∠2 = 2x + 15 .We need to find the measure of ∠4 . So from the figure we can see that , ∠2 & ∠4 are corresponding angles .So they will be equal.
⇒ ∠2 = ∠4 [ Corresponding angles ]
⇒ x + 30° = 2x + 15°
⇒ 2x - x = 30° - 15°
⇒ x = 15°
Hence the value of x is 15°
⇒ ∠4 = x + 30°
⇒ ∠4 = 15° + 30°
⇒ ∠4 = 45°
★ Hence the value of ∠4 is 45° .A professor surveys his students about their opinions on how well he taught the course. He puts this survey on the last page of his final exam. Which type of bias will most likely have the strongest effect on the survey results?
Not all students will have the access needed to find the survey.
Students may not truthfully reply because they fear it will affect their grade.
Students may not understand the wording used in the survey.
Not all students will be represented in the survey sample.
Answers
Why?
The first option is wrong because the students would have checked each page to ensure completion. We can also assume that the teacher would remind/announce students that there is a survey.
The third option is wrong because it is very unlikely. We can assume that students would ask for help when needed or randomly mark the survey to complete the survey as it is generally a opinion section that won’t be mark as there is no correct answer and it is a survey.
The fourth option is wrong as it contradicts the “he puts this survey on the last page of the exam.” Meaning that all students present for the exam would be given the survey.

You can paint 75 square feet of a surface every 45 minutes. Determine how long it takes you to paint a wall with the given dimensions. 8 ft $\times$ 5 ft
Answers
Answer:
24 minutes
Step-by-step explanation:
The Dimensions of the wall are given as:
8ft × 5ft = 40ft² or 40 square feet
We are told that: You can paint 75 square feet of a surface every 45 minutes.
Hence:
75 ft² = 45 minutes
40 ft² = x minutes
Cross Multiply
75 ft² × x = 40 ft² × 45 minutes
x = 40 ft² × 45 minutes/75 ft²
x = 24 minutes
Therefore, It will takes you 24 minutes to paint a wall with dimensions 8ft × 5 ft
A recent poll found that 76% of a random sample of 100 American movie goers thought the popcorn sold at the movie theatre was overpriced.
If the sample size was increased to 10,000 American movie-goers, what effect would this have on the estimated percentage of American movie-goers who
think the popcorn is overpriced?
Answers
Answer:
Step-by-step explanation:
Given that:
percentage of sample proportion = 76%
sample size = 100
Given that the sample proportion estimate is unbaised of the population proportion, then the percentage of all American movie-goers who think popcorn is overpriced is = 76%. Also, the mean of the sampling distribution appears to be independent of the sample size. Then, the estimate of the percentage will equally remain the same regardless it is even a sample of size 10000.

Last year at a certain high school, there were 140 boys on the honor roll and 68 girls on the honor roll. This year, the number of boys on the honor roll increased by 5% and the number of girls on the honor roll increased by 25%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
Answers
Answer:
11.5
Step-by-step explanation:
Find new values:
140(1+0.05)=147
68(1+0.25)=85
Last Year This Year
Boys 140 147
Girls 68 85
Total 208 232
Find overall increase:
208(1+r)=232
1+r=1.115385
r=0.115385
Final Answer: 11.5%
The total number of students on the honor roll increased by 11.5%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The percentage increase in the number of boys on the honor roll is 5%, which means that the number of boys on the honor roll this year is 1.05 times the number of boys on the honor roll last year:
1.05 x 140 = 147
The percentage increase in the number of girls on the honor roll is 25%, which means that the number of girls on the honor roll this year is 1.25 times the number of girls on the honor roll last year:
1.25 x 68 = 85
Therefore, the total number of students on the honor roll this year is:
147 + 85 = 232
The percentage increase in the total number of students on the honor roll is:
((232 - 208) / 208) x 100% = 11.5385%
Rounding to the nearest tenth gives an answer of 11.5%.
Therefore, the total number of students on the honor roll increased by 11.5%.

2 is the right answer.Craig measured a length as 0.034 millimeters. What is the margin of error? 0.03 mm to 0.04 mm 0.033 mm to 0.034 mm 0.0335 mm to 0.0345 mm 0.0345 mm to 0.0350 mm
Answers
C. 0.0335 mm to 0.0345 mm
Step-by-step explanation:
The least significant digit of Craig's measurement is in the 0.001 mm place. The error in the measurement is presumed to fall within half that value either side of Craig's measurement. So, the actual value is expected to be in the range ...
0.034 - 0.0005 = 0.0335
to
0.034 + 0.0005 = 0.0345
The measurement is presumed to be in the range 0.0335 mm to 0.0345 mm.
