Answer:
The length of the shadow the telephone booth is 12 ft.
Step-by-step explanation:
Given:
An adult elephant that is 10 ft tall casts a shadow that is 15 ft long.
The length of the telephone booth is 8 ft.
Now, to find the length of the shadow the telephone booth casts.
Let the length of the shadow the telephone booth be [tex]x.[/tex]
As given, an adult elephant that is 10 ft tall casts a shadow that is 15 ft long.
So, 10 ft is equivalent to 15 ft.
Thus, 8 ft is equivalent to [tex]x.[/tex]
Now, to get the length of the shadow of the booth we get cross multiplication method:
[tex]\frac{10}{15} =\frac{8}{x}[/tex]
By cross multiplying we get:
[tex]10x=120[/tex]
Dividing both sides by 10 we get:
[tex]x=12.[/tex]
Therefore, the length of the shadow the telephone booth is 12 ft.
Mary is 1 9/11 ft tall, whereas Anne is 1 7/10 ft tall. How much taller in feet is Mary than Anne? *
show ur work!!!
Answer:
= 13/110 ftStep-by-step explanation:
1 9/11 - 1 7/10
= (1-1) + (9/11 - 7/10)
= 9/11 - 7/10
= (9×10)/110 - (7×11)/110
= (90-77)/110
= 13/110
Answer:
Step-by-step explanation:
Mary is 1 9/11feet = 20/11feet
Anne is 1 7/10feet = 17/10
Mary is tall than Anne with
= 20/11 - 17/10
The LCM is 110
= (200 - 187)/110
= 13/110
= 13/110feet

if file that is 274 megabytes is being downloaded if the download is 16.4% complete how many megabytes have been downloaded round to the nearest tenth
44.9 megabytes of download is complete
Solution:
Given that,
File that is 274 megabytes is being downloaded if the download
Therefore, total megabytes of file = 274 megabytes
The download is 16.4% complete
To find: Megabytes that has been downloaded
So, we can say, 16.4 % of total megabytes of file is downloaded
Megabytes that has been downloaded = 16.4 % of total megabytes of file
Megabytes that has been downloaded = 16.4 % of 274
[tex]\rightarrow 16.4 \% \text{ of } 274\\\\\rightarrow 16.4 \% \times 274\\\\\rightarrow \frac{16.4}{100} \times 274\\\\\rightarrow 0.164 \times 274 = 44.936 \approx 44.9[/tex]
Thus 44.9 megabytes of download is complete
Final answer:
multiply 274 megabytes by 0.164, which gives 44.936 megabytes. Rounded to the nearest tenth, this is 44.9 megabytes.
Explanation:
To calculate how many megabytes have been downloaded when 16.4% of a 274 megabyte file has been completed, you simply multiply the total file size by the percentage that has been downloaded. You can convert the percentage into a decimal by dividing it by 100.
So, 16.4% as a decimal is 0.164. Now, multiply the file size by this decimal:
274 megabytes * 0.164 = 44.936 megabytes
Round to the nearest tenth, the amount downloaded is approximately 44.9 megabytes.
Make an algebraic equation out if this word problem: Sharkira went bowling with her friends. She paid 3 to rent shoes and then $4.75 for each game of bowling. If she spent a total of $21, then how many games did Shakira bowl?
Shakira played 3 full games because rounding off to 4 would increase the total.
Step-by-step explanation:
Given,
Rent of shoes = $3
Amount paid for each game = $4.75
Total paid by Shakira = $21
Let,
x be the number of games played by Shakira.
Amount paid for each game * Number of games + Rent of shoes = Total paid
[tex]4.75x+3=21\\4.75x=21-3\\4.75x=18[/tex]
Dividing both sides by 4.75
[tex]\frac{4.75x}{4.75}=\frac{18}{4.75}\\x=3.8[/tex]
Therefore,
Shakira played 3 full games because rounding off to 4 would increase the total.

Answer:
A. 1/2(14)(10)(8) – π(2.5^2)(8)
Step-by-step explanation:
I took the test and this was the correct answer. Hope this helped!
Answer:
(0.5)(14)(10)(8) – π(2.5²)(8)
Step-by-step explanation:
The rest of the question is the attached figure.
The volume of the shaded region = volume of the prism - volume of the cylinder
The volume of the prism = The area of triangle * height
= 0.5 * 10 * 14 * 8
The volume of the cylinder = The area of the circle * height
= π r² h
= π (5/2)² * 8 = π * 2.5² * 8
So, The volume of the shaded region = (0.5)(14)(10)(8) – π(2.5²)(8)

Find the area of the irregular figure.
Answer:
The area of the irregular figure is 366 cm sq.
Step-by-step explanation:
This irregular figure is made of 1 Rectangle + 1 right Triangle
Area of the Rectangle:
Length of the rectangle = 21 cm,
Width of the rectangle = 14 cm
AREA of Rectangle = LENGTH x WIDTH
= 21 cm x 14 cm = 294 sq cm
⇒Area of the Rectangle = 294 sq cm ..... (1)
Area of the Right Triangle:
Base of the rectangle = 16 cm,
Height of the rectangle = 21 cm - 12 cm = 9 cm
AREA of Right Triangle = [tex]\frac{1}{2} \times B \times H[/tex]
[tex]= \frac{1}{2} \times 16 \times 9 = 72[/tex]
⇒Area of the Right Triangle = 72 sq cm ..... (2)
Now, area of the irregular figure = Area of the( Rectangle +Right Triangle)
= 294 sq cm + 72 sq cm = 366 cm sq
Hence, the area of the irregular figure is 366 cm sq.
Answer:
366 sq. ft
Step-by-step explanation:
First, we have to find the area of the triangle. To do this we have to find the height of the triangle which can be done by subtracting 12 from 21 to get 9. Then we multiply 16 by 9 to get 144 and divide it by 2 to get 72. Now we must find the area of the rectangle. To do this we have to multiply 14 and 21 to get 294. Now we have to add the values together to get 366.

Albert has a round box of crime filled chocolates the box has a diameter of 14 centimeters what is the box’s area
Answer:
Step-by-step explanation:
The formula for the area of a circle is pi*r^2, meaning pi times the radius squared. Since we know that the diameter is 14 centimeters, we know that the radius is half of that. The radius is 7. Now, we have to square 7. 7^2=49. So the answer is 49*pi, or approximately 153.93804

If the perimeter of a triangle is 10x + 12y, and two of the sides are 4x + 14y and 4x − 2y, which is the third side?
A. 2x + 2y
B. 2x
C. 3x + y
D. x + y
Answer:
The third side is
B. [tex]2x[/tex]
Step-by-step explanation:
Given:
Perimeter of triangle = [tex]10x+12y[/tex]
Two sides of the triangle are :
1) [tex]4x+14y[/tex]
2) [tex]4x-2y[/tex]
To find the third side.
Solution:
Let the third side be = [tex]z[/tex]
The perimeter can be given as sum of all 3 sides :
[tex]4x+14y+4x-2y+z[/tex]
Combining like terms.
[tex]4x+4x+14y-2y+z[/tex]
[tex]8x+12y+z[/tex]
The perimeter given = [tex]10x+12y[/tex]
So, we have:
[tex]8x+12y+z=10x+12y[/tex]
Solving for [tex]z[/tex]
Subtracting both sides by [tex]8x[/tex]
[tex]8x-8x+12y+z=10x-8x+12y[/tex]
[tex]12y+z=2x+12y[/tex]
Subtracting both sides by [tex]12y[/tex]
[tex]12y-12y+z=2x+12y-12y[/tex]
∴ [tex]z=2x[/tex]
Thus, the third side is = [tex]2x[/tex]
