Answer:
tan C = 3/4
Step-by-step explanation:
sin C = opposite over hypotenuse
sin C = 3/5
BC = 5
AB = 3
We can use the Pythagorean theorem
a^2 + b^2 = c^2
3^2 + b^2 = 5^2
9 + b^2= 25
Subtract 9 from each side
9-9+b^2=25-9
b^2= 16
Take the square root of each side
sqrt(b^2)= sqrt(16)
b = 4
AC = 4
Tan C = opp side/ adj side
tan C = AB/ AC = 3/4
Answer:
7088 m²
Step-by-step explanation:
The area of the half-cylinder is half the area of a cylinder with the same dimensions. This half-cylinder has a radius of 0.3 m and a length of 0.8 m, so its area is ...
A = πr(r +l) = π(0.3 m)(0.3 m+0.8 m) = 0.33π m² ≈ 1.0362 m²
The area of the bottom part of the box is the sum of its lateral area and its base area.
lateral area = Ph = (2(0.6m +0.8m))(0.75 m) = 2.1 m²
base area = lw = (0.8 m)(0.6 m) = 0.48 m²
The total area is then ...
total area = half-cylinder area + lateral area + base area
= 1.0362 m² +2.1 m² +0.48 m²
= 3.6162 m²
__
The area for 1960 mailboxes will be 1960 times this area, or ...
area for week's production = 1960 × 3.6162 m² = 7087.752 m²
It will take about 7088 square meters of aluminum to make these mailboxes.
The answer is
X =3
because they both equal the amounts given
1 x 48
2 x 24
3 x 16
4 x 12
6 x 8
