Answer:
The area of a rhombus is square units.
Step-by-step explanation:
Side length of rhombus = 6 units.
Interior angle of rhombus = 120°
another Interior angle of rhombus = 180°-120° = 60°.
Draw an altitude.
In a right angled triangle
Multiply both sides by 6.
The height of the rhombus is .
Area of a rhombus is
Therefore, the area of a rhombus is square units.
Answer:
22
Step-by-step explanation:
220 x 15 ÷ 150 = 22
or each gallon gives him 10 miles.
for 220 miles he needs 22 gallons
48/8=6 is the rate per day
The area formula for both a square and a rectangle is A = L*W, only in a square, the length and width are the same. It can be rewritten then as
where s is a side. If we have the length and width of the rectangle to be 32 and 2, respectively, then the area is 32*2=64. If the square is to have the same area, 64, we will fill it into our square formula for area like this:
. To solve for s we will take the square root of both sides to get s = 8 and s = -8. The 2 things in math that will never EVER be negative are time and distance/length so -8 is out. That means that the side lengths of the square is 8 meters.
Answer:
y = -5x + 2
Step-by-step explanation:
Think about it this way:
y = ax + b
(a) = represents the slope
(b) = represents the y-intercept.
if the Y- intercept is negative so the "+" will turn to a "-"
