Answers

Answer:
4.3 in
Step-by-step explanation:
The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...
f² = d² + e² -2de·cos(F)
f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671
f ≈ √18.0671 ≈ 4.2505
The length of f is about 4.3 inches.

Answers
y=mx+b
m=slope=(y2-y1)/(x2-x1)
use the points (0,9) and (9,0)
(0-9)/(9-0) = -9/9 = -1
so m=-1
b is the y-intercept which is where x=0
the line crosses the y axis at y=9
so b=9
plugging in m and b into y=mx+b,
you get y=-x+9

Answers
Answer:
81.57 cm
Step-by-step explanation:
Given that :
Scale :
3cm : 100km
This means ; 3cm on the map represents an actual length of 100km
Actual length of shoreline = 2719 km
The length of the shoreline on the map will be :
(2719 km / 100 km) * 3cm
27.19 * 3cm
= 81.57 cm

A cylinder has a diameter of 6 cm and a height of 14 cm. What is the approximate volume of a cone with the same diameter and height
as the cylinder?
Answers
The approximate volume of a cone with the same diameter and height as the cylinder is 131.95 cm³.
How to calculate the volume of a cylinder?In Mathematics and Geometry, the volume of a cylinder can be calculated by using this formula:
Volume of a cylinder, V = πr²h
Where:
V represents the volume of a cylinder.h represents the height of a cylinder.r represents the radius of a cylinder.Radius = diameter/2 = 6/2 = 3 cm.
By substituting the given parameters into the volume of a cylinder formula, we have the following;
Volume of cylinder, V = π × 3² × 14
Volume of cylinder, V = π × 9 × 14
Volume of cylinder, V = 395.8 cm³.
For the volume of this cone, we have:
Volume of cone, V = 1/3 × πr²h
Volume of cone, V = 1/3 × 395.8
Volume of cone, V = 131.95 cm³.

B) 24
Step-by-step explanation:
A) equilateral triangle means that all sides are equal
so each side is = 24 because the perimeter = 72
72/3= 24
B) 1 side = 24 and they gave you that 10+7h = 24
so h = 2
so hight of triangle = 2
Area = 1/2(b)(h)
so 24(2)(0.5) = 24
