Ms. Day went shopping last week and spent a total of $120. Blankets cost her $16 while pillows cost her $10. Altogether, she bought 9 items. How many of each item did Ms. Day end up buying?

Answers

Answer 1

Answer:

Ms. Day bought 5 blankets and 4 pillows.

Step-by-step explanation:

Let [tex]x[/tex] denotes number of blankets and [tex]y[/tex] denotes number of pillows.

Blankets cost her $16 while pillows cost her $10 and Ms. Day spent a total of $120.

[tex]16x+10y=120[/tex]

Divide this equation by 2.

[tex]8x+5y=60\,\,...(i)[/tex]

Ms. Day bought 9 items.

[tex]x+y=9[/tex]

Multiply this equation by 5.

[tex]5x+5y=45\,\,...(ii)[/tex]

Subtract [tex](ii)[/tex] from [tex](i)[/tex]

[tex]3x=15\\x=5[/tex]

Put [tex]x=5[/tex] in [tex]x+y=9[/tex]

[tex]5+y=9\\y=9-5\\y=4[/tex]

Therefore,

Ms. Day bought 5 blankets and 4 pillows.

Answers

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

Luna has n colored cards. Some are red and some are blue. The ratio of the number of red cards
to the number of blue cards is 5:2. Luna has 60 red cards.
Find an

Answers

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

C.

Answers

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.

Find the area of the shape.

Answers

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

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

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

Answers

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.

A farmhouse shelters 10 animals, some are pigs, and some are ducks. Altogether there are 36 legs. How many pigs are there

Answers

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:

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

Answers

[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
