If H is the midpoint of GI, solve for x when GH = 5x + 2 and GI = 11x -10.

Answers

Answer 1

Answer:

Answer:

x = 14

Step-by-step explanation:

If H is the midpoint of GI, then

GI = 2GH

11x -10 = 2(5x +2)

11x -10 = 10x +4 . . . eliminate parentheses

x = 14 . . . . . . . . . . . . add 10-10x

Which equation best represents the revenue for selling n raffle tickets at $3.50 each?

Answers

You have to multiply the price of the tickets by the number of tickets sold to obtain revenue.

p = 3.5
n = number of tickets sold

r = 3.5n

3.50n - Cost of n tickets = profit

Expression 1 (E1)
$6 * 7 - {3}^(2 * 9) + {4}^(3)$
Let's Simplify E1
$42- {3}^(18) + 64 \n 42 - 38742089 + 64 \n = - 387420383$
E1, is just simply combining like terms. Plus an expression in math, is simply something that doesn't equal anything, moreover a phrase.

Expression 2 (E2)
$5 + 4 * 2 + 6 - 2 * 2 - 1$
Without Parenthesis, the expression's value is
$5 + 4 * 2 + 6 - 2 * 2 - 1 \n 5 + 8 + 6 - 4 - 1 \n 13 + 6 - 4 - 1 \n 19 - 4 - 1 \n 14$
With Parentheses, you'll get
$5 + 4 * 2 + 6 - 2 * 2 - 1 \n (5 + 4 )* 2+ 6 -2 * 2- 1 \n ((9) * 2) + 6 - 2 * 2 - 1 \n (18) + 6 - 2 * 2 - 1 \n (24) - 2 * 2 - 1 \n (24) - 4 - 1 \n 19$
In E2, you expression first has a value of 14 due to the order of operations, PEMDAS (Please Excuse My Dear Aunt Sally) standing for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. When using the order operations before the parentheses, multiplication is done first before 5 is added to 4, order states that 4 must be multiplied by 2 first before addition. However, when placing a parentheses around 5 plus 4 we are now multiplying the value of that expression, (5+4), by 2, so it becomes 9×2, because the order of operations must be followed.

The Polleys want to put in a swimming pool next summer. They need to save $6,000 over 12 months in order to achieve this goal. They set aside the same amount each month and after 7 months discovered they have saved $3,100. The Polleys know that they must adjust their plan in order to meet their goal, so they come up with the following options:Option A: Save the original amount each month but put the pool in one month later than originally planned.

Option B: Increase savings each month by $100 from their original plan

Answers

Answer:

Neither option A nor option B will allow them to meet their goal.

Step-by-step explanation:

Consider the provided information.

The Polleys want to put in a swimming pool next summer. They need to save $6,000 over 12 months in order to achieve this goal.

They set aside the same amount each month and after 7 months discovered they have saved $3,100. Now he left with 5 months (∴7+5=12 months)

Let x is the amount he was saving each month. He saved x amount for 7 months and after 7 months he has $3100.

$7x=3100$

$x=442.86$

He saved approximately $442.86 each month.

Option A Save the original amount each month but put the pool in one month later than originally planned.

That means the number of month he has now 5+1=6.

Now find how much he can save in 6 months if he save $442.86 per month.

6×442.86=2657.16

Now add his all savings as:

$3100+$2657.16=$5757.16

Thus, the option A will not allow him to meet his goal.

Now consider the option B) Increase savings each month by $100 from their original plan.

Previously he was saving $442.86 each month now increase this number by $100.

$442.86+$100=$542.86

In 5 months he can save:

5×542.86=$2714.3

Now add his all savings as:

$3100+$2714.3= 5814.3

Thus, the option B will not allow him to meet his goal.

What is measurement?

Measurement is a process through which the size, magnitude or other physical quantities that are associated with an object is taken, especially for the purpose of a scientificresearch (experiment).

In Science, some of the standard unit of measurements with the correct physical quantities include the following:

Energy: Joules.

Velocity: meters per second.

Pressure: newtons per meter.

Power: Watts.

In conclusion, we can deduce that Watts is the standard unit for the measurement of power.
