Step-by-step explanation:
the perimeter is the easiest, really. we only need to add all side lengths. there is nothing else to the perimeter calculation.
so,
perimeter = 6.5 + 2.5 + 6 = 9 + 6 = 15 ft.
area is also relatively easy for right-angled triangles, because the sides that enclose the 90° angle, act also as height of the triangle to each other.
so, it is a half-rectangle, and we only need to multiply these 2 sides (not including the Hypotenuse) and divide this by 2.
area = 6×2.5/2 = 3×2.5 = 7.5 ft²
Answer:
April took out a loan of $600 and paid it back with simple interest of $60 after 5 years. The formula to calculate interest is given the principal and the time and the interest rate is . For this problem we have to find the interest rate given . To archive that , we can just solve the equation making the interest rate the subject of the formula as shown below,
I= Prt
=> r= I/Pt
=> r= 60/600x5 = 1/50
The interest rate is 1/50 or 0.02 as a decimal. The interest rate is 2% as a percentage.
Answer:
The answer is 33.12
Step-by-step explanation:
4.6× 7.2= 33.12
Answer:
(x - 2)
Step-by-step explanation:
Given the quadratic
x² - 7x + 10
To factor consider the factors of the constant term ( + 10) which sum to give the coefficient of the x- term ( - 7)
The factors are - 5 and - 2 since
- 5 × - 2 = + 10 and - 5 + (- 2) = - 7, thus
x² - 7x + 10 = (x - 5)(x - 2)
