Answer:
50
Step-by-step explanation:
When n = 6, the length is 3 * 6 + 2 = 20 and the width is 6 - 1 = 5. We know that the perimeter of the rectangle is twice the sum of its length and width. The sum of the length and width is 20 + 5 = 25 and twice that is 25 * 2 = 50.
Answer:
60º
Step-by-step explanation:
The two triangles on the left are equilateral as the sides are all conguent.
The angles of an equilateral triangle are all 60º
Therefor the two angles to the left of angle 1 are both 60º for a combined value of 120º
Angle 1 must be 180 - 120 = 60º
The net weight of a jar of raspberry preserves will be 4.45 ounces.
The volume of the cylinder can be calculated as the product of the base of the cylinder and the height of cylinder.
The volume of cylinder= base of cylinder * height of the cylinder
⇒ volume of cylinder = πd²*h/4
Here, given that
the inside diameter of the cylinder is 1.5 inches.
d= 1.5 inches
the inside height of the cylinder is 4.75 inches.
h= 4.75 inches
putting these above values for calculating the volume of the cylinder
Volume =V = πd²*h/4
⇒ V= π*(1.5)²*4.75/4
⇒V = 8.40 cube inches
Given that the raspberry preserve weighs 0.53 ounces per one cubic.
for one cubic the weight is 0.53 ounces
for 8.40 cubic the weight will be 8.40*0.53= 4.45 ounces
Therefore The net weight of a jar of raspberry preserves will be 4.45 ounces.

This one is a bit confusing without a diagram anyway. We'll assume the typical labeling where A and B are consecutive angles, so the transverse line AB through the parallels makes A and B supplementary:
A + B = 180 degrees
12x + 46 + 7x + 1 = 180
19x = 180 - 47 = 133
x = 133/19 - 7
