Answer:
Step-by-step explanation:
Hello:
the equation is : y = ax+b
the slope is a : a×(2) = -1......( perpendicular to a line with a slope of 2 for : y=2x+1)
a =-1/2 y=(-1/2)x+b
the line that passes through (6, 2) : 2 = (-1/2)(6)+b
b = 5
the equation is : y = (-1/2)x+5
It’s 480 centimeters squared. All you had to do was multiply 10 times 8 times 6.
Answer:
4 years
Step-by-step explanation:
I = $ 400
R = 5%
P =$ 2000
I = Prt
400 = 2000 * 
* t
400 = 20 * 5 * t
400 = 100 t
t = 4 years
The area of the circle is 28 ft square.
The area of the triangle is 30 ft square.
Step-by-step explanation:
1) The area of the circle= π*r^2
where π= 3.14(default value) and "r" is the radius of the circle.
Here, Radius of the circle(r)= 3 ft
Area = 3.14*3*3
= 28.26 ft sq.= 28 ft sq(rounded to the nearest whole number)
2) The triangle has the base= 10 feet and height= 6 feet
The Area of the triangle= 1/2(b)(h)
where "b" is the base and "h" is the height of the triangle.
Substitute b=10 and h=6 ,
Area of triangle= 1/2(10 ft)(6 ft)= 60/2= 30 feet sq.
This is a proportion problem because the problem stated that the two team pennants are similar.
Pennant 1 = base = 18 in ; length = 9 inches
Pennant 2 = base = 6 in ; length = x ?
9/18 = x/6
9*6 = 18x
54 = 18x
54/18 = x
3 = x
The length of the side of the smaller pennant is 3 inches.
