a certain hose delivers 5 gallons of water in 24 seconds, how much water will the hose deliver in 10 minutes

Answers

The hose delivers 5 gallons of water in 24 seconds,
we know that 
1 min=60 seconds
10 min= 600 seconds

5 gallons of water.......................24 seconds
? gallons in ................................600 seconds

let x be the number of gallons of water we need to find out, and we use proportions
x=(5*600)/24=125 gallons 

Solve the inequality
2(3x-2)>_22

Answers

2(3x - 2) > 22

Expand (eliminate parentheses on) the left side:

6x - 4 > 22

Add 4 to each side:

6x > 26

Divide each side by 6 :

Find the coordinates of the vertices of the triangle after a reflection across the line x= -1 and then across the line y = 1.F(-2,-3), G(-3,2), H(1,-1)​

Answers

Answer:

  a.  F'(0, 5), G'(1, 0), H'(-3, 3)

Step-by-step explanation:

Reflection across x = -1 gives you the transformation ...

  (x, y) ⇒ (-2 -x, y)

Reflection across y = 1 gives you the transformation ...

  (x, y) ⇒ (x, 2 -y)

Together, these give you the transformation ...

  (x, y) ⇒ (-2 -x, 2 -y)

Applying this to point F, we have ...

  F(-2, -3) ⇒ F'(-2 -(-2), 2 -(-3)) = F'(0, 5) . . . . . . matches choice A

_____

How we found the transformation

In general, if M is the midpoint between A and B, then you have ...

  M = (A+B)/2

  2M = A+B

  B = 2M - A

So, if we want x=-1 to be the midpoint between x' and x, then we have ...

  x' = 2(-1) -x = -2 -x

Likewise, if we want y=1 to be the midpoint between y' and y, then we have ...

  y' = 2(1) -y = 2 -y

So, the transformation is ...

  (x, y) ⇒ (x', y') = (-2 -x, 2 -y)

Write the annual salary in the blanks in the following chart. Paycheck  Pay Period    Annual Salary

$1,300        monthly               ?
$1,000       biweekly              ?
$550            weekly               ?
$800          semimonthly        ?

Write the annual salary in the blanks in the following chart.

Answers

The annual salary in the blanks in the following chart are,

1300 monthly = 15600 annually

1000 biweekly = 24000 annually

550 weekly = 26400 annually

800 semimonthly = 19200 annually

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The annual salary in the blanks in the following chart,

Paycheck  Pay Period    Annual Salary

$1,300        monthly                ?

$1,000       biweekly               ?

$550          weekly                 ?

$800          semimonthly        ?

Here, We know that;

1 year = 12 months

         = 24 biweekly

         = 48 weeks

         = 24 semimonthly

Hence, We get;

Paycheck  Pay Period    Annual Salary

$1,300        monthly                $1,300 x 12 = $15,600

$1,000       biweekly               $1,000 x 24 = $24,000

$550          weekly                 $550 x 48 = $26,400

$800          semimonthly        $800 x 24 = $19,200

Thus, The annual salary in the blanks in the following chart are,

1300 monthly = 15600 annually

1000 biweekly = 24000 annually

550 weekly = 26400 annually

800 semimonthly = 19200 annually

1. Given the functions a(x) = 3x − 12 and b(x) = x − 9, solve a[b(x)] and select the correct answer below.a[b(x)] = 3x2 − 21
a[b(x)] = 3x2 − 39
a[b(x)] = 3x − 21
a[b(x)] = 3x − 39

Answers

I think the answer is A: a[b(x)] = 3x2-21 because if you make this whole expression into an equation then solve x, you will get answer A. Hope this helps! :)

Answer:

a[b(x)] = 3x − 39
