ElenaW [278]

Answer:

1) The lateral area is LA=95 cm²

2) The surface area is SA=275  cm²

The answer is the option D) 95 cm² ; 275 cm²

Step-by-step explanation:

we know that

The surface area of the box (rectangular prism) is equal to

SA=2B+LA

where

B is the area of the base

LA is the lateral area of the box

<em>Find the lateral area</em>

LA=PH

where

P is the perimeter of the base

H is the height of the box

substitute

LA=2[15+6](2.26)=94.92 cm²

Round to the nearest whole number

LA=95 cm²

<em>Find the area of the base B</em>

B=(15)(6)=90 cm²

Find the surface area of the box

SA=2B+LA

substitute the values

SA=2(90)+95=275  cm²

The first two terms in an arithmetic progression are 57 and 46. The last term is -207. Find the sum of all the terms in this pro
statuscvo [17]

Answer:

-1875

Step-by-step explanation:

An arithmetic sequence has a common difference as a sequence. Here the common differnece is -11.

So our sequence so far looks like,

(57,46,35,24....). We know the last term of the sequence is -207 and we need to find the nth term of that series so we use arithmetic sequence

a _{1} + (n - 1)d

where a1 is the inital value,

d is the common differnece and n is the nth term.

We need to find the nth term so

57 + (n - 1)( - 11) =  - 207

(n - 1)( - 11) =  - 264

n - 1 = 24

n = 25

So the 25th term of a arithmetic sequence is last term, now we can use the sum of arithmetic sequence

which is

\frac{a  _{1} + a _{n}   }{2} n

\frac{57 + ( - 207)}{2} (25) =

\frac{ -  150}{2} (25)

- 75(25) =  - 1875
