The answer should be 1 3/8
Take 3/5 of 485 you got it
Answer:
x
4
Step-by-step explanation:
4x^2 - 64
0 ; move 64 over
4x^2
64 ; divide by 4
x^2
16 ; take square root of both sides
x
4
Answer:
Area of the circle =
π m² or 132.25 π m²
Step-by-step explanation:
To find the area, we will follow the steps below.
First write down the formular for the circumference of a circle, then use the formula to find the radius of the circle after which you can now find the area of the circle.
That is;
C = 2πr
where c is the circumference of the circle and r is the radius of the circle
From the question given, circumference C = 23π
23π = 2π r
Divide both-side of the equation by 2π
23π/2π = 2πr/2π
23/2 = r
radius =
m
Formula for calculating the area of a circle is given by;
A = πr²
where A= area of the circle and r is the radius of the circle
A = π (
)²
A =
π m² or 132.25 π m²
Area of the circle =
π m² or 132.25 π m²
1. Because
info given:
Karim's dog = 15 pounds
Frank dog = 2x more pounds than Karim's dog + 1.5 pounds
(Karim) Equation 1: 15 = Frank
(Frank) Equation 2: 2w + 1.5
joining equation 1 and 2
15 = 2w + 1.5
Solve
15 - 1.5 = 2w
13.5 = 2w ÷ 2
w = 6.75
