What is the surface area of the triangular prism Not drawn to scale 2001 2376 2592 4320
liq [111]

Answer:

Option B. 2376 Square feet

Step-by-step explanation:

The following were obtained obtained from the question:

Base (B) = 24ft

Length (L) = 40ft

Height (H) = 9ft

Slant height (S) = 15ft

Surface Area (A) =?

The surface area (A) for triangular prism is given below:

A = BH + 2LS + LB

Where:

B is the Base

L is the Length

H is the Height

S is the Slant Height

A is the Surface Area

Using the above equation, the surface area can be obtained as follow:

A = BH + 2LS + LB

A = (24x9) + (2x40x15) + (40x24)

A = 216 + 1200 + 960

A = 2376 ft2

lianna [129]

Answer:

70 members in 2016

Step-by-step explanation:

In 2016

Let the number of members= x

They all paid y amount

Total fees= 42

Xy= 42...... equation 1

In 2017

Members= x+20

They paid y-0.1

Total fees = 45

(X+20)(y-0.1)= 45…equation 2

Xy -0.1x +20y -2= 45

Using values from equation 1

42-0.1(42/y) +20y -2= 45

-4.2/y+20y-5= 0

20y² -4.2 -5y = 0

100y² -25y -21= 0

Solving quadratically

Y= 0.6 or -0.35

We are dealing with price so y Is

definitely a positive number

Y= 0.6

If y= 0.6

Solving for x

Xy= 42

X= 42/0.6

X=70

There were exactly 70 members in 2016
