Answer:
150 ft/min
Step-by-step explanation:
The change in altitude per minute will have the units of ft/min.
We see that we are given the number of feet: 2250 ft, as well as the number of minutes: 15 min.
So, to get ft/min, we can divide 2250 ft (the distance) by 15 min (time) to get the rate: 2250/15 = 150 ft/min
Thus, the change in altitude per minute is 150 ft/min.
Hope this helps!
Answer:
-15 per minute
Step-by-step explanation:
2250/15 = 150
Since it's descending, height is decreasing.
Hence rate of change of height is -15 per minute
Solve for x
: 6x+ 8 = 9
Answer:
1/6
Step-by-step explanation:
6x+8= 9
Subtract 8 from both sides:
6x+8-8= 9-8
6x= 1
Divide by 6 on both sides
6/6x= 1/6
x= 1/6
Answer: x=1/6
Step-by-step explanation:
subtract the 8 from the left side to the right side to get 9-8= 1. then you will have 6x=1. divide six on both sides to get x=1/6

A. X=4
B. Y=4
C. X=4Y
D. Y=X+4
Answer:
A
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
Here the line passes through all points with an x- coordinate of 4, thus
x = 4 → A
At the park, there is a triangular sandbox with base = 12ft and height = 4ft. A drawing of the sandbox is shown above. Brie wants to make another, similar sandbox at home with base=8ft.
Your question is not clear, but it looks as though you want to know how Brie can make a similar sandbox with base = 8ft.
Answer:
For Brie to make a similar sandbox, he must use a base = 8ft, and height = (8/3)ft
Step-by-step explanation:
It is possible for Brie to make a similar triangular sandbox with base = 12ft and height = 4ft.
All he must ensure is that the ratio of base to height of the original sandbox is the same ratio of base to height of the one he is trying to make.
The original sandbox is 12:4
Because he wants to use a base = 8ft, the sandbox he is trying to make is 8:x
Where x is the height of the sandbox he is trying to make.
Then for these sandboxes to be similar, the ratio 12:4 = 8:x
=> 12/4 = 8/x
12x = 8 × 4
12x = 32
x = 8/3
The height must be (8/3)ft
14. It costs a pool cover manufacturer $0.15 per square foot for the material they use to make pool covers. If a certain circular pool requires a cover with a 24-foot diameter, find the cost for the material
The area of the pool cover is calculated using the formula for the area of a circle, πr². After finding the area, it is multiplied by the cost per square foot to find the total cost of the material, which is approximately $67.86.
Explanation:To calculate the cost of material required to cover a pool, we first need to calculate the area of the pool cover. Since the pool is circular and has a diameter of 24 feet, the radius would be half of the diameter, which is 12 feet. The formula to calculate the area of a circle is πr², so the area of the pool cover would be π*12² which equals approximately 452.39 square feet.
Next, knowing that the cost of the material per square foot is $0.15,we multiply the area by the cost per square foot, 452.39*.15 would give us approximately $67.86. Therefore, the cost of the material for the pool cover is about $67.86.

#17: A rectangular shape has an area of 150 square units. The sides of the
rectangle measure (x + 3) and (x - 2). What is the value of x? (Type the final
answer as x=# without any space. Example: x=35 If there are two possible
values of x, write the final answer as follows: x=35 and x=36) *
Answer:
The only possible value of x is 12
Step-by-step explanation:
The rectangular shape has an area of 150 square units. The sides of the rectangle measures (x + 3) and (x - 2). The value of x can be computed below
area of a rectangle = length × breadth
area = 150 unit²
The sides are (x + 3) and (x - 2)
Therefore,
(x + 3)(x - 2) = 150
x² -2x + 3x - 6 = 150
x²+ x - 6 = 150
x²+ x - 6 - 150 = 0
x²+ x - 156 = 0
(x - 12)(x + 13) = 0
Therefore,
x = 12 or x = -13
It cannot be - 13 because the sides cannot result to negative . We are left with only 12.
x = 12
The only possible value of x is 12
The value of x is 12
The dimensions of the rectangle are given as:
Length = x + 3Width = x - 2The area is given as:
Area = 150The area of a rectangle is:
[tex]Area = Length \times Width[/tex]
So, we have:
[tex](x + 3)(x -2) = 150[/tex]
Expand
[tex]x^2 + 3x - 2x - 6 = 150[/tex]
[tex]x^2 + x - 6 = 150[/tex]
Subtract 150 from both sides
[tex]x^2 + x - 156 = 0[/tex]
Factorize the above equation
[tex](x + 13)(x - 12) = 0[/tex]
Solve for x
[tex]x = -13[/tex] or [tex]x =12[/tex]
The value of x cannot be negative.
So, the value of x is 12

Using the dimensions of a new scale drawing created using a scale factor of 0.15, find the dimensions of the original rectangle.
Width:
Length:
Answer:
Width- 15.8 ft.
Length- 32 ft.
To find the dimensions of the original rectangle when given the dimensions of a new scale drawing using a scale factor of 0.15, divide the corresponding dimensions of the scale drawing by 0.15.
Explanation:The scale factor of 0.15 means that the new dimensions in the scale drawing are 0.15 times the original dimensions. To find the dimensions of the original rectangle, divide the corresponding dimensions of the scale drawing by 0.15.
Let's say the width and length of the new scale drawing are 10 units and 15 units, respectively. To find the original width and length, divide 10 by 0.15 and 15 by 0.15.
The original width would be 66.67 units (10 / 0.15) and the original length would be 100 units (15 / 0.15).

What is a decimal that is equivalent to the fractior
32/100 enter the answer in the box.
Answer:0.32
Explanation:
The reason why this is the answer is because if you look at a place value chart, you could see that hundreds is the second place after the decimal point so you would put the numerator right after the decimal point.
A decimal that is equivalent to the fraction 32/100 is 0.32.
How can we convert a fraction to a decimal?We can convert a fraction to a decimal by dividing the numerator by the denominator. For example, to convert 32/100 to a decimal, we divide 32 by 100, which gives us 0.32.
To convert a fraction to a decimal, we divide the numerator (top number) by the denominator (bottom number).
In this case, we want to convert 32/100 to a decimal. Dividing 32 by 100 gives us 0.32 as the decimal equivalent of the fraction.
A fundamental mathematical concept is the ability to transform a fraction to a decimal. In a fraction, the denominator denotes the total number of parts in the whole, whereas the numerator denotes the number of pieces. Divide the numerator by the denominator to convert a fraction to a decimal. To obtain the decimal equivalent of 32 in this situation, we divide 32 by 100. By multiplying this decimal by 100, we can also convert it to a percentage, which gives us 32%.
Therefore, the decimal equivalent of 32/100 is 0.32.

Answer:
its the third option
Step-by-step explanation:
the one with 2 rings on the second longest angle 2 lines on longest side one side and 1 line on the shortest side
All the described pairs of triangles that are reflected, rotated, or both, can be proven congruent by the SAS postulate because such rigid transformations preserve the congruency of sides and angles.
Explanation:To determine which pair of triangles can be proven congruent by the SAS (Side-Angle-Side) postulate, we look for two sides of a triangle and the included angle that are congruent to two sides and the included angle of another triangle. When a triangle is reflected across a line, rotated 90 degrees, or both reflected and rotated, it maintains its size and shape, thus the corresponding sides and angles remain congruent.
A reflection or rotation (including a combination of both) is a type of rigid transformation which preserves the size and shape of figures. Hence, all the given pairs of triangles can be proven congruent to the original triangle through the SAS postulate, as rigid transformations do not alter the congruity of sides and included angles.
