You use the formula A= 1/2(B)(H)
So the area would be: (1/2)(6)(6)
= 18

Answer:

Step-by-step explanation:

First sequence : 10,9.5,9,8.5,...

Let's see the difference between 2 numbers :
10 - 9.5 = 0.5
9.5 - 9 = 0.5
9 - 8.5 - 0.5

So on and so on. So, the common difference between these numbers are 0.5

Next sequence : 200,100,50,25, ...

We see, to get from one number to another, we divide it by 2 / multiply it by 1/2.

200 x 1/2 = 100
100 x 1/2 = 50
50 x 1/2 = 25

So on and so on. So, the common ratio of these numbers are 1/2.

K over 6 plus 8 equals 5

UNO [17]

Answer:

k= -18

Step-by-step explanation:

k/6 +8=5 (subtract 8 from both sides)

k/6= -3 (Multiply by 6 on both sides)

k=-18

Which ordered pairs are solutions to the inequality 2x+y>−4?

hichkok12 [17]

we will proceed to resolve each case to determine the solution

we have

$2x+y>-4$

$y>-2x-4$

we know that

If an ordered pair is the solution of the inequality, then it must satisfy the inequality.

case a) $(5,-12)$

Substitute the value of x and y in the inequality

$-12>-2*5-4$

$-12>-14$ ------> is True

therefore

the ordered pair $(5,-12)$ is a solution of the inequality

case b) $(-3,0)$

Substitute the value of x and y in the inequality

$0>-2*-3-4$

$0>2$ ------> is False

therefore

the ordered pair $(-3,0)$ is not a solution of the inequality

case c) $(-1,-1)$

Substitute the value of x and y in the inequality

$-1>-2*-1-4$

$-1>-2$ ------> is True

therefore

the ordered pair $(-1,-1)$ is a solution of the inequality

case d) $(0,1)$

Substitute the value of x and y in the inequality

$1>-2*0-4$

$1>-4$ ------> is True

therefore

the ordered pair $(0,1)$ is a solution of the inequality

case e) $(4,-12)$

Substitute the value of x and y in the inequality

$-12>-2*4-4$

$-12>-12$ ------> is False

therefore

the ordered pair $(4,-12)$ is not a solution of the inequality

Verify

using a graphing tool

see the attached figure

the solution is the shaded area above the line

The points A,C, and D lies on the shaded area, therefore the ordered pairs A,C, and D are solution of the inequality

Write a recursive formula and an explicit formula for the following arithmetic sequence. 14,17,20,23,26

Zarrin [17]

The recursive formula is $a_{1}$ = 14; $a_{n}$ = $a_{n-1}$ + 3

The explicit formula is $a_{n}=3n+11$

Step-by-step explanation:

The recursive formula of the nth term of the arithmetic sequence is

$a_{1}$ = first term; $a_{n}$ = $a_{n-1}$ + d, where

$a_{1}$ is the first term in the sequence
$a_{n}$ is the nth term in the sequence
$a_{n-1}$ is the term before the nth term
n is the term number
d is the common difference.

The explicit formula of the nth term of the arithmetic sequence is

$a_{n}=a+(n-1)d$ , where

$a_{n}$ is the nth term in the sequence
a is the first term
n is the term number
d is the common difference

∵ The arithmetic sequence is 14, 17, 20, 23, 26

∴ The first term is 14

∵ 17 - 14 = 3

∴ The common difference is 3

∵ The recursive formula is $a_{1}$ = first term; $a_{n}$ = $a_{n-1}$ + d

∵ $a_{1}$ = 14

∵ d = 3

∴ $a_{1}$ = 14; $a_{n}$ = $a_{n-1}$ + 3

The recursive formula is $a_{1}$ = 14; $a_{n}$ = $a_{n-1}$ + 3

∵ The explicit formula is $a_{n}=a+(n-1)d$

∵ a = 14

∵ d = 3

∴ $a_{n}=14+(n-1)3$

- Simplify the right hand side

∴ $a_{n}=14+3n-3$

- Add like terms

∴ $a_{n}=3n+11$

The explicit formula is $a_{n}=3n+11$

an empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute. At the same time another 1200 gallon

ser-zykov [4K]

Answer: 80 minutes

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each tank:

An empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute.

So, the amount of water of the tank is equal to the filling rate, 6 liters per minute (6m)

Tank 1 =0 (empty )+ 6m =6m

The second 1200 gallon tank full of water is being drained at a rate of 9 gallons per minute.

Tank 2 = 1200-9m

So, the amount of water in the tank is equal to the amount of water already in the tank (1200 g), minus the draining rate (9m)

Since both tanks will have the same amount of water:

6m = 1200-9m

Solving for m (minutes):

6m+9m= 1200

15m = 1200

m= 1200/15

m= 80 minutes

Feel free to ask for more if needed or if you did not understand something.
