Marsha went shopping at Best Buy and spent $75.25. If the sales tax was 8.75%, how much was her total bill?

Answer:

B.  (-1,2) and (-5,-2)

Step-by-step explanation:

Substitute x + 3 in for y in the second equation.  you get

[tex]x + 3 = x^{2} + 7x + 8\\x^{2} + 6x + 5 = 0[/tex]

(x + 1)(x + 5) = 0

x + 1 = 0    or  x + 5 = 0

x = - 1       or     x = -5

Using the first equation, let x = -1  and x = -5 in order to get the corresponding values for y

y = -1 + 3 = 2           and y = -5 + 3 = -2

So, B is the correct answer.

Answer:

8 Pigs.

Step-by-step explanation:

~ P = the number of pig

~ D = the number of ducks

p + d = 10

  4p + 2d = 36

4(10 - d) + 2d = 36

40 - 4d + 2d = 36

40 - 2d = 36

-40       = -40

    -2d = -4

    -2      -2

        d = 2 ducks

p + d = 10

p + 2 = 10

   Therefore, 8 pigs. :)) hope this helped you :))

Answer:  the volume is 1/12 ft³

Step-by-step explanation:

Multiply the area of the base times the height:

1/8 × 2/3 = 2/24 or 1/12

the ft² times ft becomes ft³

So the volume is 1/12 ft³

Answer:

The answer is C

Step-by-step explanation:

The plumber works $90 per hour and has earned a total of $955, to find the number of hours he worked, you divide the total amount of money by the amount of money he earned every hour. Which would be [tex]\frac{955}{90}[/tex] = H or 90H = 955.

Answer:

no it is not a right angle triangle

Answer: 600 ml

Step-by-step explanation:

Let the volume of the solution be represented by x.

Therefore, we can form an equation based on the information given which will be:

= 4% × x = 24.

4/100 × x = 24.

0.04 × x = 24

0.04x = 24

x = 24/0.04

x = 600

The volume of the solution is 600ml

Answer:

7 m

Step-by-step explanation:

We are told that;

100 cm = 1 m

Thus; 2.54 cm = 2.54 × 1/100 = 0.0254 m

This means that;

1 inch = 0.0254 m

Thus; 275 inches will give; 275 × 0.0254/1 = 6.985 m

Approximating to the nearest metre gives 7 m

Answer:

10. 264

11. 13

Step-by-step explanation:

10- When we are doing perimeter we add all the sides together. Since it's a square this time, we know all the sides are even at 66ft.

 66+66+66+66= 264

 I added 4 times for each side we have and we get the perimeter of 264

11- When dealing with area, all we need is two numbers. To get area we multiply the length and width. If we have the area and want either length or width, we can still easily do that. All we have to do is divide the area from your given number.

 65 divided by 5 is 13

 Area divided by Length is Width

Answer:

#10= 264

#11= 13

Step-by-step explanation:

#10: We can see that this is a square because it says so in the question so we can assume that if it is a square then all the lengths and widths are 66 feet. 4(66) = 264 or 66+66+66+66 = 264

#11: 65/5 = 13 because it is dealing with area, simply just divide the total of area by the known length to get the width.

Answer:

number one :

volume = LxWxH

as it is a cube all lengths are the same substitute the values in V= 14x14x14

exponent are when you multiply a value by itself for example 2x2 can be written as 2²

in this case , the answer would be option 1.14³

Answer:

n = 84 and there are 24 blue cards

Step-by-step explanation:

I'm guessing you're either trying to find n or the number of blue cards.

To find the number of blue cards:

Luna has 60 red cards and the ratio of red to blue cards is 5:2.

If you divide 60 by 5 (the number of red cards divided by the ratio for red cards) you get 12, which would be 1 in the ratio. The number in the ratio for blue cards is 2, so multiply 12 by 2 and you get 24. Therefore, the number of blue cards is 24.

If the explanation is confusing (which I know it is, sorry) you can look at it like this, and this is also a check:

The ratio of red to blue cards can be written as 5/2. If you do 5 ÷ 2, you get 2.5 and if you divide 60/24, you get 2.5

To find n, the number of cards Luna has, just add the number of red cards and the number of blue cards: 60 + 24 = 84

Answer:

Exact Area =  3pi   square units

Approximate Area = 9.42    square units

I used pi = 3.14 to get the approximation.

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

Explanation:

This is a three quarter circle since one quarter of it has been taken away.

Let's find the area of the full circle

A = pi*r^2

A = pi*2^2

A = 4pi

Now let's divide by 4 to find the area of just a quarter slice

(4pi)/4 = pi

One quarter slice is pi square units. Since we want three of these quarter slices, this means 3pi is the exact area of the shape shown.

This approximates to 3*pi = 3*3.14 = 9.42

Answer:

uh thanks for the points

Step-by-step explanation:

Answer:

Step-by-step explanation:

For example, suppose it takes you 15 minutes to travel 6 miles. The time elapsed is 15 minutes divided by 60 minutes = 0.25 hours, and your speed is 6 miles divided by 0.25 hours which equals 24 mph.

For an average person:

1 mile = 2,000 to 2,500 walking steps

1 km = 1,250 to 1,550 walking steps

10,000 steps = 4 to 5 miles

Answer:

multiply 63280 by 1.5% (.015).  The answer is $949.20

Step-by-step explanation:

[tex]k = 1.6d[/tex]

[tex]k = 1.6(665)[/tex]

[tex]k = 1064[/tex]

The distance is 1064 km.

Answer:

A. 1,064 km

Step-by-step explanation:

1 Mile is 1,6 Kilometers

430 Miles  = 688 Kilometers (430 * 1,6)

665 Miles = 1064 Kilometers (665 * 1,6)

1- 1.6(430)= 688 Km

2. 1.6(665)=1064 Km

Using 1.6 as the consant then 430* 1.6 = 688 Km

655 * 1.6 = 1048Km

if i understand what you need properly, all you do is multiply the miles x 1.6 and you will get k. so 430miles x 1.6 = 688k

and 665miles x 1.6 = 1064k

Answer:

37.7359

Step-by-step explanation:

first you visualize the shape created

if you visualize it... it will look like a right angled triangle

and we are looking for the longest side

remember the pythagoras theorem c^2= a^2 + b^2

in this case we are looking for c

a^2= 20^2

b^2= 32^2

400+ 1024= 1424

therefore c^2= 1424

then you square root 1424

to get 37.7359

note- the answer is solely based on the information given

Actually Welcome to the Concept of the Surface areas and Volumes.

Since, we know that the lateral area of a Right circular cone is given as,

AL = πrl

here, l = slant height , r = radius of the circular base.

so now, we have to find first slant height to get the lateral surface area,

[tex]l \: = \sqrt{ {r}^{2} + {h}^{2} } [/tex]

here, r = 8 cm and h = 15,

hence,

[tex]l \: = \sqrt{64 + 225} = \sqrt{289} = 17cm[/tex]

hence, now we apply the formula,

AL = π(8) (17) cm^2

===> AL = 136 π cm^2
