Answer:

He received $6.40 in change.

Explanation:

Since he bought 2.25 pounds, you multiply that by 1.6 to get a sum of 3.6. Since he paid with a ten dollar bill, and he only has to pay 3.60, they will give him back 6.40 in change.

Hope this helped :)

Answer:

963.584 is the answer.

Answer:

Length = 12.75 feet

Width= 2.25 feet

Step-by-step explanation:

Let the length = x

Let the width= y

The length of a rectangular classroom floor is 6 feet more than twice the width

X= 6+2y

The perimeter is 30 feet.

Perimeter= 2(length+width)

Perimeter= 2(x+y)

30= 2x +2y

But x= 6+2y

30 = 2(6+2y) +2y

30= 12 +4y +4y

30-12= 8y

18= 8y

2.25 = y

30= 2x +2y

30= 2x +2(2.25)

30- 4.5= 2x

25.5= 2x

12.75= x

Length = 12.75 feet

Width= 2.25 feet

Answer:

79

Step-by-step explanation:

So we have the function:

[tex]g(t)=t^2-2[/tex]

To find g(9), substitute 9 for t. Thus:

[tex]g(9)=9^2-2[/tex]

Square:

[tex]g(9)=81-2[/tex]

Subtract:

[tex]g(9)=79[/tex]

So, our answer is 79.

And we're done!

The value of 3f(x) + 2g(x) = -5x - 2

Given f(x) = -3x, g(x) = 2x-1 are the two functions

then by the algebra of two functions(adding two functions) we can find the value of 3f(x) + 2g(x)

Now find

3f(x) = 3(-3x) = -9x            -----------(i)

2g(x) = 2(2x-1)

        = 2(2x)-2(1)                        

2g(x) = 4x-2                     ----------(ii)

Now, add the above two equation (i) and (ii)

3f(x) + 2g(x) = -9x + 4x - 2  

                   = -5x-2

Answer:

A

Step-by-step explanation:

Given

[tex]\frac{m+2}{(m-4)^2}[/tex] - [tex]\frac{m-2}{(m-4)^2}[/tex]

Since the denominators are common then express as a single fraction

= [tex]\frac{m+2-(m-2)}{(m-4)^2}[/tex]

= [tex]\frac{m+2-m+2}{(m-4)^2}[/tex]

= [tex]\frac{4}{(m-4)^2}[/tex] → A

Answer:

No answer. See below.

Step-by-step explanation:

This number is in the ten-thousands, so it has 5 digits.

Let the number have the form

abcde, where

a = ten-thousands digit

b = thousands digit

c = hundreds digit

d = tens digit

e = ones digit

"my ones digit is 2 more than my thousand digit."

e = b + 2

"the sum of my ones and thousand is my hundreds digit."

e + b = c

"3 less that my hundreds digit is my tens digit."

c - 3 = d

"my Hundreds thousand and ten thousand are the same."

c = b = a

We have 4 equations:

e = b + 2

e + b = c

c - 3 = d

c = b = a

Using the last equation, replace every c and b with a in the first 3 equations.

e = a + 2

e + a = a

a - 3 = d

Using the second equation, subtract a from both sides.

e = 0

Substitute e = 0 in the first equation.

0 = a + 2

a = -2; b = -2; c = -2; d = -5

Since a digit cannot be negative, there is a problem with this question.

Answer:

B

Step-by-step explanation:

The length of the hypotenuse, x, if (20, 21, x) is a Pythagorean triple is 29.

Pythagorean triples are represented as the triple (a, b, c) where a represents the perpendicular side, b represents the base and c represents the hypotenuse.

Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.

c² = a² + b²

Here a = 20, b = 21 and c = x.

x² = 20² + 21²

x² = 841

x = √841 = 29

Hence the length of the hypotenuse, x, is 29.

180

Step-by-step explanation:

ED 2020

The required rule describes the rotation about the origin is given as (-x, -y). And the measure of rotation is 180°.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,

The coordinate of the given point is (1, 1), and after rotation coordinates are (-1, -1) about the origin. It shifted from 1st quadrat to the 3rd quadrant. It implies,

The point rotated with an angle of 180° so that its coordinates were translated by formula,
(x, y) ⇒ (-x, -y).

Thus, the required rule describes the rotation about the origin is given as (-x, -y). And the measure of rotation is 180°.

2 1/4 miles => 1 week

1 mile => 1 ÷ 9/4

( 9/4 is an improper fraction of 2 1/4 )

12 1/2 miles => ( 1 ÷ 9/4 ) × 25/2

= 5 5/9 weeks

( 25/2 is an improper fraction of 12 1/2 )

Therefore, it will take 5 5/9 weeks for the company to replace the stretch of road.

=======================================================

Explanation:

Ignore the "45" and "59" as they aren't used in this problem. The year numbers don't matter either.  These numbers are either thrown in as filler or distraction.

We're basically being asked "we started with 21,495 and increased by 82%, what is the new value?"

Take 82% of this to get 0.82*21495 = 17,625.9 which rounds to 17,626 since it doesn't make sense to have a decimal or fractional portion of a person. So the number of workers has increased by about 17,626 people.

Add this to the original amount to get 21,495 + 17,626 = 39,121 which is the answer

--------------

As a shortcut, you could multiply 21495 by 1.82 to indicate an 82% increase

1.82*21495 = 39,120.9 which rounds to 39,121

Answer:

The amount deposited in the savings account is $11,494.12

The amount deposited in the CD account is $13,505.88

Step-by-step explanation:

Firstly, let’s calculate the amount of interest;

Interest = Amount at end of 10 years - amount deposited= 31,648 -25,000 = 6,648

Let the amount deposited in the savings account be $x while the amount deposited in the CD account be $y

Mathematically;

x + y = 25,000 ••••••••••(i)

Now the formula for simple interest is;

PRT/100

where P is the amount deposited, r is the rate and T is the time

On the savings account, amount of interest generated will be;

(x * 2.2 * 10)/100 = 22x/100

On the CD act, amount of interest generated will be;

(y * 3.05 * 10)/100 = 30.5y/100

The addition of both give the total interest;

22x/100 + 30.5y/100 = 6648

Multiply through by 100

22x + 30.5y = 664800 •••••••(ii)

From i, x = 25,000 - y

Substitute this into ii

22(25000-y) + 30.5y = 664800

550,000 -22y + 30.5y = 664,800

8.5y = 664,800-550,000

8.5y = 114,800

y = 114,800/8.5

y = $13,505.88

x = 25,000 -y

x = 25,000 - 13,505.88

x = $11,494.12

Answer:

15 ounce bag is cheaper per ounce than 9.75 ounce bag.

Step-by-step explanation:

For this problem, you should simply take the cost divide by the size for each to find the price per ounce.

$3.98 / 15oz == $0.265 per ounce

$2.98 / 9.75oz == $0.306 per ounce

Note that the 15 oz bag is a better price per ounce than the 9.75 oz bag.

As to what bag you should buy, that really should depend on more factors than just what's best per ounce.  For instance, are you really hungry enough for 15 ounces of doritos, or will 9.75 do just fine?  Also, do you even have the extra dollar it would cost to buy the bigger bag?  Just some stuff to think about.

Cheers.
