We know that
[scale factor ]=[real]/[drawing]
[real]=[drawing]*[scale factor ]
step 1
find the real values
if the base of Riley's drawing is 10 centimeters
[real]=[drawing]*[scale factor ]--------> 10*3-------> 30 cm
the base of the triangular clock face is 30 cm
the height of Riley's drawing is 15 centimeters
[real]=[drawing]*[scale factor ]--------> 15*3-------> 45 cm
the height of the triangular clock face is 30 cm
the area of the triangular clock face is-----> 45*30/2-------> 675 cm²
the answer is the option C. 675 square centimeters
Answer:
- 2 1/4 pounds of blueberries
Step-by-step explanation:
Blueberries - b, raspberries - x
<u>Equations as per question:</u>
<u>Eliminate b and solve for x:</u>
- 1/5x = x - 1 4/5
- x - 1/5x = 1 4/5
- 4/5x = 9/5
- x = 9/5 : 4/5
- x = 9/5 *5/4
- x = 9/4
- x = 2 1/4
Answer:
20 stamps
Step-by-step explanation:
Let x be Muthu's original count
Let y be Sangeetha's original count
x = 4y
x - 12 = y + 12
y = x - 24
x = 4(x - 24)
x = 4x - 96
3x = 96
x = 32
so 32 - 12 = 20
Answer:
Step-by-step explanation:
What are we calculating ??? If it is volume of a cone=1/3πr^2h
1/3×3.142×4×4×6
=100.54units cube
To calculate volume of cylinder=πr^2h
V=3.142×4×4×6
V=301.63 units cube
And where is the graph? I'll change my answer.
