Find the surface area of the prism.
weqwewe [10]

Answer:

160 m²

Step-by-step explanation:

The surface area of the prism is the sum of the area of its surfaces. This prism has 5 surfaces, namely the front, back, right, left and bottom surface.

<u>Area of front surface</u>

Area of triangle= ½ ×base ×height

Base= 6 m

Height= 4 m

Area= 6(4)= 24 m²

<u>Area of back </u><u>surface</u>

Area of back surface

= area of front surface

= 24 m²

<u>Area of right </u><u>surface</u>

Area of rectangle= length ×breadth

Length= 7 m

Breadth= 5 m

Area= 7(5)= 35 m²

<u>Area of left </u><u>surface</u>

Area of left surface

= area of right surface

= 35 m²

<u>Area of bottom </u><u>surface</u> (base of prism)

Area of rectangle= length ×breadth

Length= 7 m

Breadth= 6 m

Area= 6(7)= 42 m²

The total surface area can be found by adding all of the surface areas we have found earlier.

Total surface area

= 24 +24 +35 +35 +42

= 160 m²

a crew workers paved 2/15 mile in 20 minutes. if they work at the same rate what portion of a mile will they pave in one hour?
ANEK [815]
Since 20 min is 1/3 of a mile 20 min*3=1 hour. then u multiply 2/5 by 3 to get 6/5.

To approach a runaway a plane must be 7 descent starting from the height of 3 miles above the ground. How many miles from the ru
UNO [17]

use SOHCAHTOA 

S = sine

O = opposite edge

H = hypotenuse

T = Tangent

A = adjacent edge

C = cosine.

The extreme is where the runaway is indicated by the hypotenuse is the required distance. Therefore,

sine 7= 3/H

H = 3/sine 7= 24mi

What model describes the relationship between the amount of bacteria and time, given that the bacteria triple every two hours?
jeyben [28]
This is exponential.  Start with time increments of 1.  If we have 4^x, then the bacteria population triples every hour (x=0 -> 1, x=1 -> 4, x=2 -> 16, etc).  Now, the problem is that is quadruples every two hours.  If you substitute one hour for two, the equation becomes 4^(x/2).  (Now at 2 hours, it is 4, at 4 hours, it is 16, ect).  I am assuming that the population starts at 1, but it doesn't have to.  Let's say the starting population at time 0 is P.  Then, the population at time x would be P*4^(x/2).  You can verify this for any starting population P>=0 and for any time x>=0.

What key features are necessary and how they can be used to create the sketch of a polynomial function?
Tomtit [17]

The key features of polynomials are the vertex, axis of symmetry, x and y intercepts.

 

<span>1.    </span>The degree will help you find the end behavior.

<span>2.     </span>The vertex shows you where it changes concavity.

<span>3.     </span>X and y intercepts give you a couple of points of reference.

<span>4.     </span>Axis of symmetry is only applicable to even degree polynomials.

 

I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.
