Ms.Lee bought some Reese and a bag of chips. They cost $4.36 altogether. The chips cost $1.60 more than the Reese. How much did the Reese cost?

Answers

Answer: $1.38

Step-by-step explanation:

Let the value of the Reese be represented by x

Since the chip cost $1.60 more than the Reese, then the chip will be:

= x + 1.60

Since they cost $4.36 altogether, the value of the Reese will be:

x + (x + 1.60) = 4.36

2x + 1.60 = 4.36

2x = 4.36 - 1.60

2x = 2.76

x = 2.76/2

x = 1.38

The Reese cost $1.38

Kelly met Jesse and Liza at the max for breakfast. The graph shows Kelly’s speed during her 12 minute drive

Answers

Answer:

D. [tex]-360\,\frac{km}{h}[/tex]

Step-by-step explanation:

Physically speaking, average acceleration ([tex]\bar a[/tex]), measured in kilometers per square hour, is defined by following formula:

[tex]\bar a = \frac{v_{f}-v_{o}}{t_{f}-t_{o}}[/tex] (1)

Where:

[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final speed, measured in kilometers per hour.

[tex]t_{o}[/tex], [tex]t_{f}[/tex] - Initial and final instant, measured in hours.

The initial and final instants are, respectively:

[tex]t_{o} = 5\,min\times \frac{1\,h}{60\,min}[/tex]

[tex]t_{o} = 0.083\,h[/tex]

[tex]t_{f} = 9\,min \times \frac{1\,h}{60\,min}[/tex]

[tex]t_{f} = 0.15\,h[/tex]

If we know that [tex]t_{o} = 0.083\,h[/tex], [tex]v_{o} = 60\,\frac{km}{h}[/tex], [tex]t_{f} = 0.15\,h[/tex] and [tex]v_{f} = 36\,\frac{km}{h}[/tex], then the average acceleration of Kelly is:

[tex]\bar a = \frac{36\,\frac{km}{h}-60\,\frac{km}{h}}{0.15\,h-0.083\,h}[/tex]

[tex]\bar a = -358.209\,\frac{km}{h^{2}}[/tex]

Answers

Answer:

C- 42

Step-by-step explanation:

Answer:

C. x=42

Step-by-step explanation:

Lauren invests money in an account paying simple interest. She invests $50 and no money is added or removed from the investment. After one year, she has $50.50. What is the simple percent interest per year?

Answers

Based on the amount invested and the amount it grew to, the simple interest rate is 1%.

Lauren invested $50 and got $50.50 after a year.

What is the Simple Interest rate?

This rate can be found by the formula:

= (Difference in investment in year 1) / Amount invested x 100%

Solving gives:

= (50.50 - 50) / 50 x 100%

= 1%

In conclusion, the rate is 1%.

If n + 7 = 10, evaluate 2n - 2

Answers

Answer:

The value of 2n - 2 is 4.

Step-by-step explanation:

Given the equation

[tex]n + 7 = 10[/tex]

Subtract 7 from both sides of the equation

[tex]n+7-7=10-7[/tex]

Simplify

[tex]n=3[/tex]

Now substituting n = 3 in the equation

2n - 2 = 2(3) - 2

= 6 - 2

= 4

Therefore, the value of 2n - 2 is 4.

help please!! solve for x

im kinda bad at explaining, but basically what you have to do is find the angle to the right of the 50° angle. since theres an equilateral triangle, 180-50-90= 40. since the triangle x is in has 2 equal sides, 2 of the angles are 40. so, 180-40-40=100. sorry if that's off

isabels class has collected 90 cans in a food drive they plan to sort the cans into n bags, with an equal number of cans in each bag. write an expression to show how many cans there will be in each bag.

Answers

Answer:

cn=90, so long as c and n are whole numbers

Step-by-step explanation:

There are two variables in this equation you have here. One, n the number of bags, has already been given to you, because there can be any number of bags. The other, weĺl call it c, is the number of cans in each bag. Because there could be any number of bags, and the number of cans needed in each one is also a variable, you are left with more than one option. Any solution will work so long as the number of cans, c, per bag, n, is equal to the total, 90. There could be 9 cans in 10 bags, or 10 cans in 9 bags, or 15 cans in 6 bags or vice versa. The only way to define it for one answer is to have a set number of bags or cans per bag. Hope this helps!

Nearsightedness StudyMyopia, or nearsightedness, results from a number of genetic and environmental factors. In 1999, Quinn et al studied the relation between myopia and ambient lighting at night (for example, from nightlights or room lights) during childhood.Question 1. The data were gathered by the following procedure, reported in the study. "Between January and June 1998, parents of children aged 2-16 years [...] that were seen as outpatients in a university pediatric ophthalmology clinic completed a questionnaire on the childs light exposure both at present and before the age of 2 years." Was this study observational, or was it a controlled experiment? Explain.Write your answer here, replacing this text.Question 2. The study found that of the children who slept with a room light on before the age of 2, 55% were myopic. Of the children who slept with a night light on before the age of 2, 34% were myopic. Of the children who slept in the dark before the age of 2, 10% were myopic. The study concluded that, "The prevalence of myopia [...] during childhood was strongly associated with ambient light exposure during sleep at night in the first two years after birth."Do the data support this statement? You may interpret "strongly" in any reasonable qualitative way.Write your answer here, replacing this text.Question 3. On May 13, 1999, CNN reported the results of this study under the headline, "Night light may lead to nearsightedness." Does the conclusion of the study claim that night light causes nearsightedness?Write your answer here, replacing this text.Question 4. The final paragraph of the CNN report said that "several eye specialists" had pointed out that the study should have accounted for heredity.Myopia is passed down from parents to children. It's also reasonable to suppose that myopic parents are more likely to leave lights on in their children's rooms than other parents.

Studying the SurvivorsThe Reverend Henry Whitehead was skeptical of John Snows conclusion about the Broad Street pump. After the Broad Street cholera epidemic ended, Whitehead set about trying to prove Snow wrong. (The history of the event is detailed here.)He realized that Snow had focused his analysis almost entirely on those who had died. Whitehead, therefore, investigated the drinking habits of people in the Broad Street area who had not died in the outbreak.What is the main reason it was important to study this group?1) If Whitehead had found that many people had drunk water from the Broad Street pump and not caught cholera, that would have been evidence against Snow's hypothesis.2) Survivors could provide additional information about what else could have caused the cholera, potentially unearthing another cause.3) Through considering the survivors, Whitehead could have identified a cure for cholera.In [ ]:# Assign survivor_answer to 1, 2, or 3survivor_answer = ...In [ ]:_ = ok.grade('q7_1')Note: Whitehead ended up finding further proof that the Broad Street pump played the central role in spreading the disease to the people who lived near it. Eventually, he became one of Snows greatest defenders. I NEED HELP PLEASE!!! If a figure is dilated by a factor of 1.5, the area of the figure will change by a factor of Will mark brainliest 9.
