Answer:

= 52sqrt3

Step-by-step explanation:

Area of a trapezium is given by the formula;

1/2(a+b)h

Where a and b are the parallel sides and h is the perpendicular height.

a = 15 ft, b= 11 ft and h = 4√3

Therefore;

Area = 1/2 (15+11) 4√3

        = 1/2 × 26 × 4√3

        = 52√3 ft²

Answer:

Choice b is correct.

Step-by-step explanation:

We have to find the area of trapezoid.

The formula for area of trapezoid is:

A = 1/2 (a+b )h

In the formula a and b are parallel sides and h is perpendicular height.

In the figure, a = 15 ft , b = 11 ft , h = 4√3 ft

Hence,

A = 1/2 (15+11)(4√3)

A = 1/2 (26)(4√3)

A = 52√3 ft² is the area of trapezoid.

navik [9.2K]

Answer:

\large\boxed{d=\dfrac{e^2+e}{1-3e}}

Step-by-step explanation:

\dfrac{d-e}{3d+e}=e\\\\\dfrac{d-e}{3d+e}=\dfrac{e}{1}\qquad\text{cross multiply}\\\\(1)(d-e)=(e)(3d+e)\qquad\text{use the distributive property}\\\\d-e=3de+e^2\qquad\text{add}\ e\ \text{to both sides}\\\\d=3de+e+e^2\qquad\text{subtract}\ 3de\ \text{from both sides}\\\\d-3de=e^2+e\qquad\text{distribute}\\\\d(1-3e)=e^2+e\qquad\text{divide both sides by}\ (1-3e)\\\\d=\dfrac{e^2+e}{1-3e}

Naily [24]

Answer:

85 in intreset and 935 totoal

Step-by-step explanation:

Answer:

A = $935.00

I = A - P = $85.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Solving our equation:

A = 850(1 + (0.05 × 2)) = 935

A = $935.00

The total amount accrued, principal plus interest, from simple interest on a principal of $850.00 at a rate of 5% per year for 2 years is $935.00.
