Answer:
56 packs
Step-by-step explanation:
1) (14*24 ) - packets of macaroni altogether.
2) repack into packs of 6.
(14*24)/6 = 56 packs
You multipy 7/8 and 6 and then simplify if needed to get how long it will take
I'll help you out with 3 questions.
For #1, you kind of figured it out yourself
That 90 degree angle on paper means that m/1 and m/2 make up 90
If m1 is 50, then just subtract m1 (50) from 90, making it 40. m/2 is 40
If Angle M4 is 45 degrees then angle M3 is 180-45 since they both make up a 180 degree angle.
There are 180 degrees in a triangle
If m 8 = 78
and m 9 = 60
m 10 is 180 - 78 - 60

Answer:
- slant height: 2.1 cm
- pencil area: 51.12 cm^2
Step-by-step explanation:
The slant height (s) is the hypotenuse of the right triangle with legs of 2 cm and 0.5 cm.
s^2 = 2^2 + 0.5^2 = 4 + 0.25
s = √4.25 ≈ 2.0616 ≈ 2.1
The slant height is about 2.1 cm.
__
The surface area of the whole pencil is the sum of the areas of the circular base, the lateral area of the cylindrical part, and the lateral area of the cone.
A = πr^2 +2πrh +πrs
A = πr(r +2h +s) = (3.14)(0.5 cm)(0.5 cm + 2×15 cm + 2.1 cm)
A ≈ 51.12 cm^2
The area of the whole pencil is about 51.12 cm^2.
