Value of the given expression  8.2 x 19 using compensation method is equal to 155.8.

As given in the question,

Given expression is equal to :

8.2 x 19

Apply compensation method to make the calculation easily and get the value of the given expression we have,

8.2 x 19

Rewrite 19 as ( 20 -1 ) we get,

= 8.2 × ( 20 - 1 )

Apply distributive law multiplication over subtraction we get,

= ( 8.2 × 20 ) - ( 8.2 × 1 )

= 164.0 - 8.2

= 155.8

Therefore, value of the given expression  8.2 x 19 using compensation method is equal to 155.8.

Answer:

y = -7/4x + 22

Step-by-step explanation:

linear equation: y = mx +c, where m is the slope

when a line is parallel to another line, it means they have same slope

so the line slope, m = -7/4

now you need to find c to complete the equation

you have x,y information

replace that into linear equation together with slope value

8 = (-7/4)8 + c

8 = -14 + c

8+14 = c

c = 22

substitute m,c into the equation, you get

y = -7/4x + 22

Answer:

Width: 20 in

Length: 25 in

Explanation:

We can represent the situation with the following figure

Where x is the width of the rectangular piece of metal, (x + 5) is the length of the rectangular because it is 5 in longer than its wide, and the corners have squares of side 1 in.

Therefore, the volume of the box will be equal to

Volume = Length · Width · Height

Volume = (x + 5 - 1 - 1) · (x - 1 - 1) · (1)

Volume = (x + 3)(x - 2)(1)

Volume = (x + 3)(x - 2)

Because the length of the box will be the length of the rectangle less the length of the squares and the width of the box will be the length of the rectangle less the width of the squares.

The volume is 414 in³, so we need to solve the following equation:

414 = (x + 3)(x - 2)

414 = x² + 3x - 2x + 3(-2)

414 = x² + x - 6

414 - 414 = x² + x - 6 - 414

0 = x² + x - 420

Factorizing x² + x - 420, we get:

(x + 21)(x - 20) = 0

Then

x + 21 = 0

x + 21 - 21 = 0 - 21

x = -21

or

x - 20 = 0

x - 20 + 20 = 0 + 20

x = 20

Since x = -21 doesn't have sense, the width is x = 20 and the length is:

x + 5 = 20 + 5 = 25 in.

So, the original width is 20 in and the original length is 25 in

To know the best deal, we have to know which one gives us the least cost per gallon.

To do that we divide the price by the quantity or volume.

A) $56 for 25 gallons

B) $32.05 for 15 gallons

C) $51.29 for 23 gallons

D) $22.50 for 10 gallons

The best deal is B: $32.05 for 15 gallons, because it offers a price per gallon that is lower than the others.

To calculate the total amount accrued when you deposit the money in an account that earns compound interest you have to use the following formula

A: amount accrued

P: principal amount

t: time, years

r: interest rate, expresed as a decimal value

n: number of coumpound periods

For this exericse

The principal amount is P=$1000

The time is t= 9 years

The interest rate is 9%/100=0.09

The compounding periods are 12/year (the interest is compounded monthly) so for the 9 year time period is 9*12=108

The point of maxima of any function can be known by equating its derivative to zero. The rocket will take 1.5 sec to reach the maximum height and the maximum height is 27 feet.

The differentiation of a function is defined as rate of change of its value at a point. It can be written as g'(x) = (g(x + h) - g(x)) /(x + h - x).

Its geometric aspect is the slope of the function at a given point.

Given that,

Initial height of the launching pad is 4 feet,

Initial velocity of rocket is 48 feet/sec,

Height of the rocket as a function of time, h(t) = -16t² + 48t + 3

In order to find the time for maximum height equate h'(t) = 0 as follows,

-32t + 48 = 0

⇒ t = 48 / 32

⇒ t = 3 / 2

⇒ t = 1.5

To find the maximum height find h(t) for t = 1.5 as follows,

h(1.5) = -16 × 1.5² + 48 × 1.5 + 3

= -36 + 60 + 3

= -36 + 63

= 27

Hence, the time taken by the rocket to reach the maximum height is 1.5 sec and the maximum height reached is 27 feet.

The percentage change though = 25%.

What is Percentage?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.

Bob's price dropped by $0.30, or BLANK, between April 1 and May 1.

Considering that the initial price was $3.20, the percentage change was 0.3/3.2, or 9.37%.

Bob's cost grew by $0.30 between May 1 and June 1 (or BLANK).

Price change was -0.3/3.5 = -8.57% since the initial price was $3.50.

Consider that the prices at the gas station across the street are consistently 20% more than those at Bob's. When gas costs $3.50 instead of $3.20, the price difference between Bob's and the prices across the street is BLANK in absolute terms.

Since 20% of $3.50 is greater than 20% of $3.20, the absolute difference will be greater when gas costs $3.50.

Let's say the Federal Reserve increases the federal funds rate objective from 2% to 2.5%. The Fed increased its target by almost BLANK percentage points as a result of this change.

It is 1% for each percentage point. Half a percentage point is the difference between 2% and 2.5%. However, the percentage change was 25% (0.5/2).

The value of f(4) is 1125.

Here,

we have given the value of f(1)=9 and f(n)=5f(n-1) and we have to find out the value of f(4).

From the above equation of f(n), it is clear that for finding value of  f(4) we have to find value of f(3).

And for f(3) we have to find out the value of f(2)

So,

first, we will find out value of f(2) and then eventually value of f(3) and f(4) by using the given formula of f(n)

The given formula for f(n) is

f(n)=5f(n-1)

So,

f(2)=5f(2-1)

f(2)=5f(1)

f(2)=5×9

f(2)=45

Now,

f(3)=5f(3-1)

f(3)=5f(2)

f(3)=5×45

f(3)=225

And,

f(4)=5f(4-1)

f(4)=5f(3)

f(4)=5×225

lenght=177

width= 46

Step-by-step explanation:

l= lenght w=widht

l= 4*w -7

perimeter= 2l+2w = 446

so:

2(4*w -7)+2w=446

8w-14+2w=446

10w=460

w=46

and

l=4*46-7

l= 177

Answer:

Explanation:

To find the dimensions of the playing field, let's assign variables. Let's say the width of the field is "w" yards.

According to the problem, the length of the field is 7 yards less than quadruple the width. This can be written as:

Length = 4w - 7

The perimeter of a rectangle is the sum of all its sides. In this case, the perimeter is given as 446 yards.

The formula for the perimeter of a rectangle is:

Perimeter = 2(Length + Width)

Substituting the given values, we get:

446 = 2(4w - 7 + w)

Now, let's solve the equation step-by-step to find the value of "w" and then find the dimensions of the field.

1. Distribute 2 to the terms inside the parentheses:

446 = 2(5w - 7)

2. Simplify the expression inside the parentheses:

446 = 10w - 14

3. Move -14 to the other side of the equation:

446 + 14 = 10w

4. Combine like terms:

460 = 10w

5. Divide both sides of the equation by 10:

46 = w

Now that we have the value of "w", we can find the length of the field by substituting it into the equation for the length:

Length = 4w - 7

Length = 4(46) - 7

Length = 184 - 7

Length = 177 yards

Therefore, the dimensions of the playing field are:

Width = 46 yards.

Length = 177 yards.

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x + 4 ← is in slope- intercept form

with slope m = 1

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{1}[/tex] = - 1

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = - 1 and (a, b ) = (3, - 3 ) , then

y - (- 3) = - 1 (x - 3) , that is

y + 3 = - (x - 3)
