Option A and C get the perimeter 39.4cms.

Step-by-step explanation:

Perimeter is the sum of all the sides.

As they given the values in the picture, You observe the option A. Add 7.4cm two times because it's opposite side is equal. You'll get 14.8cm and add 12.3cm two times you'll get 24.6cm Add 12.3cm and 24.6cm you'll get 39.4cms as answer.

Observe the option C. Add 9.8 two times because it's opposite side is equal. You'll get 19.6. Add 9.9cm two times, you'll get 19.8cm. Add 19.6 and 9.9cm, you'll get 39.4cms as answer.

andreev551 [17]

Answer:

Numărul de puncte:

Irina a obținut = x = 245 puncte

Teodor a obținut = y = 314 puncte

Andrei a obținut = z = 286 puncte

Step-by-step explanation:

Să ne reprezentăm

Numărul de puncte:

Irina a primit = x

Teodor got = y

Andrei got = Z

Irina, Teodor și Andrei au participat la un concurs.

Irina și Teodor au obținut 559 de puncte împreună

x + y = 559 ....... Ecuația 1

Teodor și Andrei au obținut 600 de puncte împreună

y + z = 600 ...... Ecuația 2

y = 600 - z

Irina și Andrei 531 puncte.

x + z = 531 ....... Ecuația 3

Substitui

600- z pentru y în ecuația 1

x + 600 - z = 559

Colectează ca termeni

x - z = 559 - 600

x - z = -41 ..... Ecuația 4

Combinând ecuația 3 și 4 împreună

x + z = 531 ....... Ecuația 3

x - z = -41 ..... Ecuația 4

Am face și ecuația 3 și 4 împreună pentru a elimina z

2x = 490

x = 490/2

x = 245 puncte

Rezolvarea pentru z folosind ecuația 4

x - z = -41 ..... Ecuația 4

245 - z = -41

Colectează ca termeni

z = 245 + 41

z = 286 puncte

Rezolvarea pentru y

y = 600 - z

y = 600 - 286

y = 314 puncte

Prin urmare,

Numărul de puncte:

Irina a obținut = x = 245 puncte

Teodor a obținut = y = 314 puncte

Andrei a obținut = z = 286 puncte

Maria makes a quilt. The main design is 5 feet long on each side. Then she adds a

fenix001 [56]

Answer:

1. 6 feet

2. 1 ft

0.5 ft

Step-by-step explanation:

The given dimensions for the quilt are;

The length of each sides of the quilt = 5 feet long, therefore, the shape of the quilt is a square

The area, A, of the finished quilt plus the border = 36 ft²

1. Given that the quilt's shape is that of a square, we have;

A = (side length)²

Side length = √A = √36 = 6 feet

2. Given that the initial length of the sides of the quilt are 5 feet, we have;

Increase in total length by border = Final length of quilt - Initial length of quilt

Increase in total length by border = 6 ft - 5 ft = 1 ft

The increase in total length of the quilt by the border = 1 ft

3) Given that the increase in the length by the border = 1 ft

The sum of the width of the border on both sides = 1 ft

Border width on one side + Border width on the other side = 1 ft

Since there is equal border width on each side of the quilt, we have;

2 × Border width = 1 ft

Border width = width of the border = 1 ft/2 = 0.5 ft.

Calculate the future value in five years of $8,000 received today if your investments pay future value a. 5 percent compounded a

zhannawk [14.2K]

The Future value is:

a) $10,210.25

b) $11,220.41

c) $12,308.99

d) $18,938.90

e) $44,835.28

What is future value?

The future value (FV) of any asset can be understood as an increase in its value at a fixed rate over a period of time. For a given principal sum P, rate of interest r, and time period t, the future value of an asset can be calculated as:

FV=P*(1+r) ^t

We can find future value as shown below:

P=$8,000

t=5 year

a) r=6%=0.06

FV=8000*(1+0.05) ^5

=8000*(1.0) ^5

=$10,210.25

b) r=7%=0.07

FV=8000*(1+0.07) ^5

=8000*(1.07) ^5

=$11,220.41

c) r=9%=0.09

FV=8000*(1+0.09) ^5

=$12,308.99

d) r=9% compounded semiannually

= 0.09

t=2*5=10

FV=8000*(1+0.09) ^10

=8000*(1.09) ^10

=$18,938.90

e) r=9 percent compounded quarterly

=0.09

t=5*4=20

FV=8000*(1+0.09) ^20

=8000*(1.09) ^20

=$44,835.28

Mary-Ann has $28, which is 2 1 3 as much money as Lola has. How much money does Lola have?

Anuta_ua [19.1K]

Answer:

The amount that Lola has is $12

Step-by-step explanation:

Let

x ----the amount that Lola has

we know that

Two One-third multiplied by the amount that Lola has is equal to $28

$(2\frac{1}{3})x=28$

Convert mixed number to n improper fraction

$2\frac{1}{3}=\frac{2*3+1}{3}=\frac{7}{3}$

substitute

$\frac{7}{3}x=28$

Solve for x

$x=28(3)/7\\x=\$12$
