The mean would be 85 :)
Step-by-step explanation:
Write an expression for the area of the rectangle below.
Rectangle area = length × width
Rectangle area = ( 7x - 2 )( 3x + 4 )
Rectangle area = 21x^2 + 22x - 8
Thus the correct answer is option D .
The coach of a lacrosse team bought ice cream cones to celebrate a victory. A single-scoop cone was $3 and a double-scoop cone was $5. The coach bought 15 cones and paid $57. A system of equations describing this situation could be written in the form below where s represents the number of single cones and d represents the number of double cones. What is the sum of A, B, C and E?
Answer:
The number of
Single scoop cones = s = 9
Double scoop cones = d = 6
Step-by-step explanation :
Let t he number of
Single scoop cones = s
Double scoop cones = d
A single-scoop cone was $3 and a double-scoop cone was $5. The coach bought 15 cones and paid $57.
The system of equation
= s + d = 15.. Equation 1
s = 15 - d
3s + 5d = 57.... Equation 2
We substitute 15 - d for s
3(15 - d) + 5d = 57
45 - 3d + 5d = 57
Collect like terms
- 3d + 5d = 57 - 45
2d = 12
d = 12/2
d = 6
Solving for s
s = 15 - d
s = 15 - 6
s = 9
Therefore,
The number of
Single scoop cones = s = 9
Double scoop cones = d = 6

What is the other shape in the composite figure besides the rectangular prism?
triangular pyramid
square pyramid
triangular prism
cube
Answer:
cube
Step-by-step explanation:
The shape in the middle of the two rectangular prism would be a cube. This is the case since the angle at the base of the rectanglular prism forms a 90-degree angle. This indicates that the line is a straight line and would also form a 90-degree angle with the bottom angles as well. This would ultimately indicate that it forms a square, and since the shape is a 3-Dimensional shape it would be classified as a cube in this image.
Answer:
Triangular Prism
Step-by-step explanation:
The middle shape is a rectangular prism.
The top and bottom is a Triangular Prism.
A rectangle has a length of 5 cm and a
width of 4 cm. Every dimension is
tripled to form a second rectangle.
What is the ratio of the areas of the two
rectangles?
Answer:
1:9
Step-by-step explanation:
First Rectangle:
width x height = area
4 * 5 = 20
Second Rectangle:
(4*3)*(5*3)=x
12 * 15 = 180
Ratio:
180/20 = 90
1:9
Answer:
1:9 or 1/9
Step-by-step explanation:
if a rectangle is 5cm × 4cm
Area of rectangle= length ×width
= 5 × 4
=20cm²
if we triple dimensions of a rectangle we get the second rectangle
therefore, (5×3)cm × (4×3)cm
Area of second rectangle= 12 ×15
=180cm²
ratio is 20/180= 1/9 (Ans.)

How do box plots work?
Answer:
A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. ... In a box plot, we draw a box from the first quartile to the third quartile. A vertical line goes through the box at the median. The whiskers go from each quartile to the minimum or maximum.

==================================================
Explanation:
Let's solve (x-2)(x-5) = 0 and doing so leads to x = 2 or x = 5. Plugging either value in for x makes the expression (x-2)(x-5) become 0.
Let's pick a value to the left of x = 2, let's say we pick x = 0. Plug this into the expression (x-2)(x-5) and we get the following:
(x-2)(x-5)
(0-2)(0-5)
(-2)(-5)
10
The result is a positive number, meaning that (x-2)(x-5) is positive when we select a value smaller than 2.
Now we'll repeat this with a value between 2 and 5. Let's say we pick on x = 3.
So,
(x-2)(x-5)
(3-2)(3-5)
(1)(-2)
-2
The result is negative, so (x-2)(x-5) is negative when 2 < x < 5. This immediately rules out choices C and E.
Unfortunately, answer choices B and D won't work either for similar reasoning. The only thing left is choice A.
Side note: The answer in interval notation is [tex](-\infty, 2] \cup [5, \infty)[/tex] so basically it's everything but values between 2 and 5; however, x = 2 and x = 5 are part of the solution set.
Another side note: if you flip the inequality sign from [tex]\ge[/tex] to [tex]\le[/tex], then the answer would be choice C.

Oil leaks out of a tanker at a rate of r=f(t) liters per minute, where t is in minutes. If f(t)=Ae^(−kt), write a definite integral expressing the total quantity of oil which leaks out of the tanker in the first hour.
Answer:
The definite integral expressing the total quantity of oil, 'V', which leaks out of the tanker in the first hour is given as follows;
[tex]V = \int\limits^{60}_0 {A \cdot e^{(-k \cdot t)}} \, dt[/tex]
Step-by-step explanation:
From the question, we have;
The rate at which oil leaks out of the tanker, r = f(t)
The unit of the oil leak = Liters per minute
The unit of t = Minutes
[tex]If \ f(t) = A \cdot e^{(-k \cdot t )}[/tex]
Therefore, we have;
The definite integral expressing the total quantity, 'V', of oil which leaks out of the tanker in the first hour is given as follows;
[tex]V = \int\limits^{60}_0 {A \cdot e^{(-k \cdot t)}} \, dt[/tex]
Therefore, we have;
[tex]\int\limits^{60}_0 {A \cdot e^{(-k \cdot t)}} \, dt = \dfrac{A \cdot e ^{60 \cdot k} - A}{k \cdot e ^{60 \cdot k} }[/tex]
Three sides of a quadrilateral are the same length, g, The length of the fourth side is 7 inches,
The perimeter of the quadrilateral is 10 inches,
Write an equation that represents
the situation
7
3
7
Answer:
Step-by-step explanation:
Let s represent the length of each of the three sides mentioned. The length of the fourth side is 7 inches. Adding the lengths of the four sides together yields 10 inches: g + g + g + 7 = 10 (inches)
Then 3g + 7 = 10, or 3g = 3, or g = 1.
This equation is OK, but there's no solution, since 3g or just 3 is less than 7. With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.
An environmentalist tracks the total number of trees y in a park after x years of a planting program. The line of best fit for the data is represented by the equation y = 3x + 15. What is the percent change in the total number of trees from x = 4 to x = 7? Round your answer to the nearest percent.
Answer:
33.33%
Step-by-step explanation:
The line of best fit for the data is represented by the equation y = 3x + 15.
At x = 4,
y = 3(4) + 15 = 27
At x = 7,
y = 3(7) + 15 = 36
We need to find the percent change in the total number of trees from x = 4 to x = 7.
So,
[tex]\%=\dfrac{36-27}{27}\times 100\\\\=33.33\%[/tex]
So, the required percentage change is equal to 33.33%.
