Hey there look like you need some help.
If I give you the correct answer mark me brainleist

First you would find the area of the square:        230*230= 52,900Next you would find the area of one on the triangles:        230*187=43,010 * 1/2=  21,505Then you would multiply the area of the one triangle by four:       21,505*4= 86,020Finally, you would add the area of the square to the combined area of the triangles:        86,020+ 52,900=138,920

WILL GIVE BRAINLIEST!!! How many terms are in the geometric sequence having a first term of 2, a last term of 32, and a common r
Elza [17]

Answer:

3

Step-by-step explanation:

first term a= 2

last term tn= 32

common ratio r= -2

number of terms

= tn=ar^n-1

32 = 2*(-2)^n-1

divide both sides by 2

32/2 = 2*(-2)^n-1/2

16 = (-2)^n-1

Then...use 16 in the power of 2

(-2)^4 = (-2)^n-1

The bases (-2), cancels out

so we have: 4 = n-1

collect like terms

4-1 = n

3 = n

n= 3

A rectangle measures 15 1/4 feet by 8 11/15 feet. If the length and width are extended by 1 2/3 Feet each find the area of the n
zubka84 [21]

Answer:

New area is 175 42/45 feet ²

Step-by-step explanation:

Given data

Length l= 15 1/4

To proper fraction = 61/4 feet

Width w= 8 11/15

To proper fraction = 131/15 feet

Extention = 1 2/3

To proper fraction = 5/3

Dimensions of new rectangle

Length =61/4+5/3 = 183+20/12

LCM = 12 = 203/12

Width = 131/15+5/3= 131+25/15

LCM = 15 = 156/15

Area = 203/12*156/15= =31668/180

=31668/180

= 7917/45

= 175 42/45 feet ²

I need help with number 52! And I haven’t done 51
Wittaler [7]

Answer:

  51.  A/P = (2.2t +25)/(2.6t +29)

  52.  A/P for t=0 is about 0.862

         A/P for t=4 is about 0.858

Step-by-step explanation:

51. The ratio of the two given functions is ...

  r(t) = A/P

  r(t) = (2.2t +25)/(2.6t +29)

__

52. Fill in the required numbers and do the arithmetic.

  r(0) = (0 +25)/(0 +29) = 25/29

  r(0) ≈ 0.862

_

  r(4) = (2.2·4 +25)/(2.6·4 +29) = 33.8/39.4

  r(4) ≈ 0.858

The salary ratio is approximately flat at 0.86 over the 4-year period. It is declining slightly each year.
