Apple exponent rule a^-b= 1/a^b

4^-4= 1/4^4

=1/4^4

4^4=256

so therefore, it is 1/256

Answer: A deposit of 50$

Step-by-step explanation:

First, 9 Degrees below 0. 0-9 is -9 so this is a negative integer.

Second, deposit of 50$  so pretend your bank amount is x so x+ 50$ would be x + 50! Which is a positive integer

Finally, A weight loss of 10 pounds, x- 10 is probably a negative integer.

Hope this helps!

The answer is 6,400 I hope you get a good grade

Answer: h ≤ -5

explanation:

4h - 3 ≤ -23

if you add 3 to both sides it becomes

4h ≤ - 20

then if you divide both sides by 4

h ≤ - 5

hope this helps :)

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

Work Shown:

x = cost of labor per hour

3x = cost of the 3 hours of labor

3x+141 = cost of labor plus parts = total cost

3x+141 = 336

3x = 336-141

3x = 195

x = 195/3

x = 65

The hourly wage is $65 per hour for labor.

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

Check:

1 hour = 65 dollars in labor costs

3 hours = 3*65 = 195 dollars in labor costs

195+141 = 336 dollars total

The answer is confirmed.

Answer: 3 square yards

Step-by-step explanation:

they will each have 3 sq yards because if mathew has 3 siblings that each need an equal amount you would do -

9sq yards is what needs to be split up evenly by 3 children

so i would do

and with that you would get 3

Answer: 3 square yards

Step-by-step explanation:

If you Divid:

9 ÷ 3=?

You'll get the answer 3

So that's how you get your answer

Put 60 as x and get no of days .

Option C

Answer:

C. 75

Step-by-step explanation:

The scatter plot shows a positive correlation since the y-value increases as the x-value increases.

Given equation of the line of best fit:

y = 0.95x + 17.56

To estimate the number of days it takes for a 60-year-old house to be sold, input x = 60 into the given equation:

⇒ y = 0.95(60) + 17.56

⇒ y = 57 + 17.56

⇒ y = 74.56

⇒ y = 75 (nearest whole day)

Therefore, according to the line of best fit, an estimate of the number of days it will take for a 60-year-old house to be sold is 75 days.

Extrapolation

For this problem, we have used the line of best fit (regression line) to predict a value of that is outside the range of the original data. When using values of x outside the range to predict corresponding values of y, this is called extrapolation.  These predictions can be unreliable because there is no evidence that the relationship described by the regression line is true for all values of x.  Therefore, caution should be applied in these cases.

Answer:

Step-by-step explanation:

Im no expert but you would need information on the length and width of the rectangular garden and walkway. To figure this out you would need the information on the width of the walkway and length and width of the rectangle.

Let's pretend a rectangle has a width of 4 and length of 6. I would do 4x6. Then for the walkway lets pretend the width is 3. Since the we know the length of the rectangle is 6 and the width 4, I would do 2(6x3)+2(4x3).

I don't really know if this is correct but let me know if it iss!:))

Area = 52x + 5

Step-by-step explanation:

Area = Length × Width

Length = 6.5 ft

Width = 8x+5 ft

Area = 6.5 × (8x+5)

Area = 52x + 5

Answer: Your answer is 1,350 ft.

Step-by-step explanation:

Just do this: y divided by z. You should get 25. Now 25 x 54. There is your answer. Hope this helped! :D

Answer:

13.4

Step-by-step explanation:

pythagoras theorem- A square plus B square is equal to C square

12 square plus 6 square - 180 squared

square root of 180 - 13.416....

Answer: so it goes -12-->4-->-5--->-7--->-1-->-9-->-6-->6-->45--->-36 And then your there! make sure you look at which numbers are positive and negative in my answer. your welcome :)

Step-by-step explanation:

Note that:

If you multiply 2 negative numbers, your answer will be positive.

If you multiply 1 negative & 1 positive number, your answer will be negative.

If you multiply 2 positive numbers, your answer will be positive.

Start:

-4 x 3 = -12

-2 x -2 = 4

25/(-5) = -5

(-49)/7 = -7

-5 x (1/5) = -1

(-3)(-3)(-1) = (-3 * -3)(-1) = (9)(-1) = -9

(3/4) x -8 = (3 * -8)/4 = 3 * -2 = -6

-18/-3 = 6

-9 x - 5 = 45

12/(-1/3) = 12 * -3 = -36

Finish.

~

the code will be the sum of all your answers:

-12 + 4 - 5 - 7 - 1 - 9 - 6 + 6 + 45 - 36 = -21

-21 is your code.

Answer:

102

Step-by-step explanation:

Let the unknown measure be x

So all the angles add up to 180

therefore,

13 + 65 + x = 180

78 + x = 180

x = 180 - 78

x = 102

Investment in Company A by investor = $6100

Investment in Company B by investor = $6480

The decrease in value of the stock of company A is 2%

The decrease in value of the stock of company B is 10%

Value of wealth that investor lost in company A = 6100× 2/100

= 61×2

= $122

The decline in the value of the stock of company B = 6480×10/100

= 648×1/1

= $648

The total decline in the wealth of the investor= 122+648

= $770

The combined wealth of investor in both companies= 6100+6480

= $12580

Percentage of decline in the stock account of investor= 770×100/12580

= 77000/12580

= 6.1%

The total percentage decline in investor's stock account is 6.1%

Just made it up on the spot :)

Jared invited his friends over for lunch. He bought a pizza and ate 3/4 of it himself before calling his friends. He called Bob, Matombe, Steve, Owen, and Bill. Now, Jared must divide the 1/4 of the pizza into 5 parts for his friends to eat.

Answer:

Step-by-step explanation:

If 1/4 is divided by 5 we can think about it as 1/4 is a quarter of a whole and we need to divide that quarter in 5 equal parts.

Story Problem:

Alexa has 5 more days to finish reading the ELA book assigned by her teacher. She still has to read 1/4 of the book. What fraction of the book she should read on each of the 5 days to ensure she will be done in time?

(1/4 ) / 5 = (1/4) *(1/5) = 1 / 20

If Alexa reads 1/20 of the book each day she will finish the book in 5 days.

Step-by-step explanation:

similar triangles

I chose a box of cereal-------> rectangular prism

Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).

Length: 20 cm

Width: 8 cm

Height: 32 cm

Part 2).

 Describe the shape of the cross-section when the box is cut parallel to the base

the shape of the cross-section would be a rectangle of dimensions

20 cm x 8 cm

Part 3)

What is the surface area of the box? 

surface area=2*area of the base+perimeter of the base*height

area of the base=20*8=160 cm²

perimeter of the base=2*[20+8]-----> 56 cm

height=32 cm

surface area=2*160+56*32------> 2,112 cm²

the answer part 3) is

2,112 cm²

Part 4)

What is the surface area of the box if it is scaled up by a factor of 10?

we know that

surface area of the larger box=[scale factor]²*surface area original box

scale factor=10

surface area original box=2,112 cm²

so

surface area of the larger box=10²*2,112-----> 211,200 cm²

the answer part 4) is

211,200 cm²

Part 5) 

What is the volume of the box?

volume of the box=L*W*H-----> 20*8*32------> 5,120 cm³

the answer Part 5) is

5,120 cm³

Part 6) 

What is the volume of the box if it is scaled down by a factor of 1/10

we know that

the volume of the smaller box=[scale factor]³*volume original box

scale factor=1/10

volume original box=5,120 cm³

so

volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³

the answer part 6) is

5.12 cm³

The length is⇒ 6 in., the width is⇒ 2 in., and the height is⇒ 16 in.
