Answer:
21.V=1746.1
22.V=1922.7
23.V=54.4
Step-by-step explanation:
V=h*w*l V=pir^2*h
V=12*8*14 . V=pi*4^2*8
V=1344 . V=402.1
V1+V2=1344+402.1=1746.1
V=pi*r^2*h V=2/3*pi*r^3
V=pi*6^2*13 V=2/3*pi*6^3
V=pi*36*13 V=2/3*pi*216
V=1470.3 V=452.4
V1+V2=1470.3+452.4=1922.7
V=1/3pi*r^2*h V=1/3pi*r^2*h
V=1/3pi*2^2*6 V=1/3pi*2^2*7
V=8pi V=28/3pi
V=25.1 . V=29.3
V1+V2=25.1+29.3=54.4
Steps to solve:
4 - 3x = 2(x - 3)
~Distribute
4 - 3x = (2 * x) + (2 * -3)
~Simplify
4 - 3x = 2x - 6
~Subtract 4 to both sides
4 - 4 - 3x = 2x - 6 - 4
~Simplify
-3x = 2x - 10
~Subtract 2x to both sides
-3x - 2x = 2x - 2x - 10
~Siimplfy
-5x = -10
~Divide -5 to both sides
-5x/-5 = -10/-5
~Simplify
x = 2
Best of Luck!
Answer:
46 units^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is
SA = 2(lw +lh+wh) where l is length, w is width and h is height
SA = 2 (2.5* 4+ 2.5*2 + 4*2)
= 2 (10+5+8)
= 2( 23)
= 46 units^2
We just have to multiply 20 by 10mm, which is 200mm. 100mm is equal to one centimeter, so the body length of the insect under the microscope is two centimeters.
Answer:
Area of the base is 10.5 cm².
Step-by-step explanation:
Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases
Vertical height = 6 cm
Volume = 63 cm³
From the formula,
63 = Area of the triangular base × 6
Area of the base = 
= 10.5 cm²
Therefore, area of the base is 10.5 cm².
