Answers
Answer:
24
Step-by-step explanation:
she sold 12 glasses of lemonade in one our times by two and you get 24
Missy could have sold between 14 and 24 glasses of lemonade in two hours, given that she sold between 7 and 12 glasses per hour.
To find out the range of glasses Missy could have sold in two hours, we need to calculate the minimum and maximum number of glasses sold per hour and then find the totals for two hours:
Step-by-Step Explanation
Minimum glasses per hour: 7 glassesMaximum glasses per hour: 12 glassesTotal for two hours (minimum): 7 glasses/hour * 2 hours = 14 glassesTotal for two hours (maximum): 12 glasses/hour * 2 hours = 24 glassesHence, Missy could have sold between 14 and 24 glasses of lemonade in the two hours.

hope this helps
Answer:
B. 2005
Step-by-step explanation:
We have been given that population of deer in a certain national park can be approximated by the function [tex]P(x)=150(1.07)^x[/tex], where x is the number of years since 1995. We are asked to find the year in which population will reach 300.
To solve our given problem, we will equate [tex]P(x)=300[/tex] and solve for x as:
[tex]300=150(1.07)^x[/tex]
[tex]\frac{300}{150}=\frac{150(1.07)^x}{150}[/tex]
[tex]2=(1.07)^x[/tex]
Now, we will take natural log on both sides as:
[tex]\text{ln}(2)=\text{ln}((1.07)^x)[/tex]
[tex]\text{ln}(2)=x\text{ln}(1.07)[/tex]
[tex]x=\frac{\text{ln}(2)}{\text{ln}(1.07)}[/tex]
[tex]x=10.2447[/tex]
[tex]x\approx 10[/tex]
Now, we will find 10 years after 1995 that is [tex]1995+10=2005[/tex].
Therefore, the population will be 300 in year 2005 and option B is the correct choice.

a)) A 55 m long and 35 m broad park is surrounded by a 2.5 m wide
(i) Find the area of the path.
Answers
Answer:
Area of the path is 475 m².
Step-by-step explanation:
Let us first draw the diagram for the given question.
Here rectangle ABCD represents a park whose length is 55 m and breadth is 35 m. The shaded portion shows the path all around the park whose width is 2.5 m.
Now, length of rectangle ABCD, l = 55 m
breadth of rectangle ABCD, B = 35 m
Now, width of the path = 2.5 m
So, length of rectangle PQRS, L = 55 + 2.5 + 2.5 = 60 m
breadth of rectangle PQRS, B = 35 + 2.5 + 2.5 = 40 m
Now, to calculate the area of shaded portion or the area of the path, we will subtract the area of the park or area of rectangle ABCD from the area of rectangle PQRS.
Now, area of rectangle PQRS, A₁ = L × B = 60 × 40 = 2400 m²
Area of rectangle ABCD, A₂ = l × b = 55 × 35 = 1925 m²
So, area of the path = A₁ - A₂ = 2400 - 1925 = 475 m²
Hence the area of the path is 475 m².
What’s the surface area of the right cone below? 8;15
Answers
Answer:
Circle the 15 in the diagram, that's the correct answer
Answer:
184π units²
Step-by-step explanation:
see attached for reference
given sloped height = 15 units
base radius = 8 units
the height of the cone can be found by using the Pythagorean equation
(sloped height)² = height ² + (base radius)²
15² = h² + 8²
h² = 15²-8² = 161
h = √161
Base surface area = πr² = π 8² = 64π units²
Lateral Surface Area,
= πr √(r² + h²)
= π(8) √[ (8)² + (√161)² ]
= 8π√(64 + 161)
= 8π√225
= 8π (15)
= 120π
Surface area = base area + lateral surface area
= 64π + 120π
= 184π units²

Write the equation of the line that passes through (4, -8) and is parallel to the line y = -2x - 13.
Answers
Answer:
y=-2x
Step-by-step explanation:
Parallel means same slope.
y-y1=m(x-x1)
y-(-8)=-2(x-4)
y+8=-2x+8
y=-2x+8-8
y=-2x
Let’s rewrite the equation
y=-2x-13
Knowing that the equation is parallel to this will only tell us the slope. When an equation is parallel to another it has the same slope but a different y-intercept. So, our equation will also have a slope of -2.
Our current equation is y=-2x+b
Let’s solve for b. We’ll do this by substituting the point into the equation and solving
y=-2x+b
*substitute point*
-8=-2(4)+b
*multiply -2 and 4*
-8 = -8 +b
*add 8 on both sides*
0=b
That will finish our equation. Our final equation is y=-2x+0, or simply y=-2x

At the start of the month, Suzanne's clothing store website had 7,278 hits. At the end of the month, it had 50,165 hits. If each hit lasted 1.5 minutes, then what was the approximate total number of minutes on the website for this month? A. 64,500 B. 43,651 C. 21,955 D. 102,200
Answers
Answer:
Option A. 64,500Explanation:
1. First, calculate the number of hits had during the month, by difference:
50,165 hits - 7,278 hits = 42,887 hits2. Round the result to obtain an approximation = 43,000 hits
3. Multiply by the time that each lasted:
43,000 hits × 1.5 min/hit = 64,500 minutes.Hence, the answer is the option A.
Chandler is walking 1/16 km every 10 minutes. How many kilometers will he walk in 1 hour?!
Answers
Answer:
[tex]\frac{3}{8} or\ 0.375\ km[/tex]
Step-by-step explanation:
Given: Chandler walk 1/16 km every 10 minutes.
First, lets find how many 10 minutes in one hours or convert minutes in hours.
∴ Time= [tex]\frac{60}{10} \ h[/tex]
Now, finding kilometres travelled in 1 hour.
Distance travelled= [tex]\frac{1}{16} \times \frac{60}{10} = \frac{1}{16} \times 6[/tex]
Distance travelled = [tex]\frac{3}{8}[/tex]

Between 4:00 p.m. and 7:00 p.m. the temperature in Boxerville dropped 18
degrees. If the temperature at 7:00p.m. is 64 degrees, what was the
temperature in degrees at 4:00 p.m.?
Answer here
SUBMIT
Answers
To find the temperature in Boxerville at 4:00 p.m. after a drop of 18 degrees by 7:00 p.m. (with a 7:00 p.m. temperature of 64 degrees), we add the dropped degrees back to find the original temperature was 82 degrees.
The question asks to find the temperature at 4:00 p.m. in Boxerville given that it dropped 18 degrees by 7:00 p.m., and the temperature at 7:00 p.m. is 64 degrees. To solve this, we simply need to add the 18-degree drop back to the 7:00 p.m. temperature to find the original temperature at 4:00 p.m.
To find the temperature at 4:00 p.m., we calculate:
Temperature at 7:00 p.m.: 64 degrees
Temperature drop: 18 degrees
Original temperature at 4:00 p.m.: 64 degrees + 18 degrees = 82 degrees
Therefore, the temperature at 4:00 p.m. was 82 degrees.
Make a conjecture about two different non vertical lines in the same plane that have the same slope
Answers
Two different non-vertical lines in the same plane with the same slope are parallel to each other. The slope determines the angle of the line with respect to the x-axis, and lines with the same slope do not intersect if they have different y-intercepts.
Explanation:When making a conjecture about two different non-vertical lines in the same plane that have the same slope, one can conclude that these two lines are parallel to each other. This is because the slope of a line represents the steepness and direction of the line, and lines with the same slope will never intersect and are hence parallel. The slope is determined by the ratio of the rise (change in y) over the run (change in x), and as illustrated in Figure A1, the slope is consistent along the entire length of a straight line. If two lines have the same slope but different y-intercepts, they will maintain the same angle with respect to the x-axis but will be positioned at different locations in the plane.
An example is given in Figure A1, where a line has a y-intercept of 9 and a slope of 3. The slope and y-intercept are represented by the 'm' and 'b' terms in the linear equation y = mx + b. Therefore, even if two lines have the same 'm' value, if their 'b' values are different, the lines will be parallel but not coincident (overlapping).

Ranking the three from best to worst will be: point, line, plane. The justification is that, the starting concept determines the next one.
Step-by-step explanation:
The connection can be described by starting with the fundamental concept,procedure or strategy that give rise to the others. In this case, to form a line, you need to have points that join to extend infinitely in different directions. This means the point, is the fundamental concept, that will give the line.A plane is an infinite set of points that form a connected flat surface extending infinitely far in all direction. So here again, the plane exist where there is a set of points. However, a plane is named by three points that are in the plane but not in the same line. Hence, before naming a plane, the concept of a line should be considered. Ranking the three from best to worst will be: point, line, plane.

749/d ∙ d/749=1
what does D equal?
Answers
Final answer:
To find the value of d in the equation 749/d ∙ d/749 = 1, we can simplify the equation and solve for d. Canceling out the like terms and cross multiplying leads us to the solution: d = 1.
Explanation:
To find the value of d in the equation 749/d ∙ d/749 = 1, we need to simplify the equation and solve for d.
We can start by canceling out the like terms: 749 and d. Multiplying the numerators and denominators gives us:
(749/d) ∙ (d/749) = (749 ∙ d) / (d ∙ 749)
Since the two fractions are equal to 1, we can set up the equation:
(749 ∙ d) / (d ∙ 749) = 1
Next, we can cross multiply:
749 ∙ d = d ∙ 749
Now, we can divide both sides of the equation by 749:
d = d ∙ 749 / 749
Simplifying further:
d = 749 / 749
Finally, we arrive at the solution:
d = 1

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line will be y=3x+6.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is constant.
Since the line is parallel to y=3x+2, the slope of the line will be the same as this line, therefore, will be equal to 3. The equation of the required line will be,
y = 3x + c
Now, the value of constant, c can be found by substituting the point in the equation of the line, therefore,
9 = 3(1) + c
9 = 3 + c
c = 6
Hence, the equation of the line will be y=3x+6.
