6 pencils = 2 rulers
1ruler= 2 eraser
12 pencil = 4 rulers
4rulers=8 eraser
so 8 erasers are equal to 12 pencils
Answer:
4:10
Step-by-step explanation:
Absolute value is the number made positive. For -4:10, it would be 4:10. I don't know what the colon means but that's what it is.
Answer: 3. Point F.
Step-by-step explanation:
The missing statement is: Point F' corresponds to______
- Point D.
- Point E'.
- Point F.
- Point E.
The missing picture is attached.
By definition, the original figure (The figure before the transformation) is called "Pre-image" and the figure obtained after the transformation is called "Image".
You know that the triangle is obtained by transforming the triangle ; therefore, the triangle is the Pre-Image and the triangle is the Image.
Therefore, given the point (which is a vertex on the triangle ) you can identify that its image is (which is the corresponding vertex on the triangle ).
You can also verify it by seeing the angle and the angle . Notice tthat:
Therefore, based on the explained before, you can conclude that the point corresponds to the point .
Answer:
A = 7,241.2454026112 square mm.
or exact : A = 2,304.96*π sq mm
Step-by-step explanation:
Cylinder formula: A = π* r^2 + 2 *π * r* h + π*r^2
is the surface area.
d = 2r = 39.2 mm
h = 39.2 mm
r = 19.6 mm
A = π* r^2 + 2 *π * r* h + π*r^2
A = 2* π* (19.6)^2 + 2π (19.6)*(39.2)
A = 2,413.748467537 + 4,827.496935
A = 7,241.2454026112 square mm.
or
A = 2*pi* (768.32 + 384.16)
A = 2*1,152.48* pi
A = 2,304.96*π sq mm
Answer:
Smaller: 19
Larger: 20
Step-by-step explanation:
- X+3(x+1)=79
- X+3x+3=79
- 4x=79-3
-4x=76
-x=19
Two consecutive:
19 and 20
19 + 3(20)= 19 + 60= 79
