Answer:

440\ ft^2

Step-by-step explanation:

we know that

The area of the backyard pool to be resurfaced is equal to the area of the base plus the area of its four lateral sides.

so

A=B+PH

where

B is the area of the base

P is the perimeter of the base

H is the depth of the pool

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

B=(L)(W)

substitute the given values

B=(20)(10)=200\ ft^2

<em>Find the perimeter of the base P</em>

P=2(L+W)

substitute the given values

P=2(20+10)=60\ ft

we have

H=4\ ft

<em>Find the area of the backyard pool to be resurfaced</em>

A=B+PH

substitute the values

A=200+60(4)

A=440\ ft^2

The account balance on April 1st is $50.51. On April 15th, a payment of $15.00 is made. On April 25th, a purchase of $19.27 is m
matrenka [14]
Hi there!

The true answer is as follows:

Finance charge = $0.76
To get this you need to take the account balance on April 1st and multiply by the annual rate of 18%, which looks like this:

$50.51 × 0.18 = 9.0918
Then you divide your answer by 12 for the months of the year to get:

9.0918 ÷ 12 = 0.75765
Which rounds to $0.76 for you finance charge

New balance = $55.54
To get this you take the account balance on April 1st and subtract the payment of $15.00 and then add the purchase of $19.27 and the finance charge of $0.76, like so:

$50.51 - $15.00 = $35.51 + $19.27 + $0.76 = $55.54

In the arithmetic sequence {13, 6,-1,-8,...}, what is the common difference?
pav-90 [236]

════════ ∘◦❁◦∘ ════════

<h3>Answer = -7</h3>

════════════════════

<h3>Known</h3>

a = 13

U2 = 6

U3 = -1

U4 = -8

════════════════════

<h3>Question</h3>

d = ..?

════════════════════

<h3>Way to do </h3>

#since it gives a lot of number, i will just pick one of the nth term, ill choose U2

Un = a + (n-1)d

U2 = 13 + (2-1)d

6 = 13 + d

6 - 13 = d

d = -7

════════════════════

<h3>Note</h3>

• The formula of arithmetic sequence

<h2>Un = a + (n-1)d</h2>

n = nth term

a = first term

d = common difference

Just keep getting more homework.<br> i really need help
rusak2 [61]

Answer:

1. x = 1, y = -3

2. x = 3, y = 4

Step-by-step explanation:

Here, we want to solve the sets of simultaneous equations;

a) -y = 5x-2

-3y = -5x + 14

substitute 1 into ii

3(5x-2) = -5x + 14

15x - 6 = -5x + 14

15x + 5x = 14 + 6

20x = 20

x = 20/20

x = 1

from;

-y = 5x - 2

y = -5x + 2

y = -5(1) + 2

y = -3

b) -2y = -6x + 10

2y = x + 5

Substitute ii into i

-(x + 5) = -6x + 10

-x - 5 = -6x + 10

-x + 6x = 10 + 5

5x = 15

x = 15/5

x = 3

2y = x + 5

2y = 3 + 5

2y = 8

y = 8/2

y = 4
