Answer:

Step-by-step explanation:

the park has 1/5 white birds

out of this number, 2/3 are ducks

ducks=(1/5)/(2/3)=3/10

hungry ducks=(3/10)/(3/4)=6/15

Answer: 381

Step-by-step explanation:

Lets solve this in two parts, first the bottom one, then the upper one

Bottom one is a rectangle so 3*7*16=336

The one above is a triangular prism or something. You use base times height to find it. The base is 3*5/2=7.5

7.5 times height of 6 is 45.

Now add the 2 together to get 381

Answer:

congruent: 1 & 8,

congruent & corresponding: , 4&8

supplementary: 2&5, 3&5, 3&4

i don’t see how anything can be congruent AND supplementary unless the angles are both 90.... hope this helped

Answer:

Brand A price per diaper: 0.3

Brand B price per diaper: 0.3

Brand B is the better buy.

This can be found by taking the price of each brand and dividing it by the amount of diapers in each pack.

ex:

$11.49 / 36 = $0.32 (then round to nearest tenth)

Step-by-step explanation:

sqrty = y^(0.5)

1 / sqrty = y^(-0.5).

-1/5 = -0.2.

Therefore we have (1 / sqrty)^(-1/5)

= [y^(-0.5)]^(-0.2)

= y^[(-0.5)(-0.2)] (Law of indices)

= y^0.1

= 10th square root of y. (2nd option)

Answer:

  π/3

Step-by-step explanation:

The given integral does not exist. We assume there is a typo in the upper limit, and that you want the integral whose upper limit is (√3)/2.

It is convenient to make the substitution ...

  x = sin(y) . . . . so, y = arcsin(x)

 dx = cos(y)·dy

Then the integral is ...

  [tex]\displaystyle\int_0^{\sqrt{3}/2}{\dfrac{\cos{y}}{\sqrt{1-\sin^2{y}}}}\,dy=\int_0^{\sqrt{3}/2}{dy}=\left.\arcsin{x}\right|\limits_0^{\sqrt{3}/2}\\\\=\arcsin{(\sqrt{3}/2)}=\boxed{\dfrac{\pi}{3}}[/tex]

Well since the polynomial is of not an even or odd sequence like the polynomial in the question is

[tex]3x^6+2x^4-x^3+7\\[/tex]

like the degree 6 is even the degree 4 is even but the degree 3 is odd so since the sequence breaks the polynomial above has no real x-intercepts meaning it has complex roots.

Answer:

108 votes

Step-by-step explanation:

There were 180 votes in the election and Jordan received 10% of them.

180 × 0.10 = 18

Jordan received 18 votes the first time. This year, he received 6 times as many votes.

18 × 6 = 108

Jordan received 108 votes this year.

Answer:

you should multiply 2 by 2.1 with that you would get the width of the dog run.

The width would be 4.2

Step-by-step explanation:

Answer:

W = 4.2 ft

Step-by-step explanation:

By what number must we multiply 5 to get the actual length 10.5 feet?

5x = 10.5 ft, or x = 2.1 ft, where x is the length

The following is true:  5 : 2 = L : W, or

  5      L

----- = -----

  2       W

Since we have L (10.5 ft) and need W, we solve the above equation for W:

5W = 2L, so that W = (2/5)L

Since L = 10.5 ft, W must be W = (2/5)(10 1/2 ft)

                    2           21

Then W = --------- * -------- ft = 21/5 ft = 4.2 ft                W = 4.2 ft

                     5           2

Answer:

a) x = 14

b) The perimeter of △QRS is 77 units.

Step-by-step explanation:

a) Due to the question asking for a solution using the Triangle Proportionality Theorem, it is assumed that △RQS is similar to the smaller triangle inside it.

Let us define the point at which the line inside △RQS meets line RQ as T, and the point at which that same line meets line RS as V.

Hence, △RTV ~ △RQS.

According to the Triangle Proportionality Theorem:

[tex]\frac{RT}{RQ} = \frac{TV}{QS} = \frac{VR}{SR}[/tex]

Hence, we can substitute all values that we know from the diagram:

[tex]\frac{2x - 2}{2x - 2 + 13} = \frac{TV}{17} = \frac{21 - 7}{21}[/tex]

After getting this information, all we have to do is simplify and solve the equation:

[tex]\frac{2x - 2}{2x - 2 + 13} = \frac{21 - 7}{21}[/tex]

[tex]\frac{2x - 2}{2x + 11} = \frac{14}{21}[/tex]

[tex]\frac{2x - 2}{2x + 11} = \frac{2}{3}[/tex]

[tex]3(2x - 2) = 2(2x + 11)[/tex]

[tex]6x - 6 = 4x + 22[/tex]

[tex]6x - 4x = 22 + 6[/tex]

[tex]2x = 28[/tex]

[tex]x = 14[/tex]

To verify this answer, we can plug in the value of x into the equation:

[tex]\frac{2(14) - 2}{2(14) - 2 + 13} = \frac{2}{3}[/tex]

[tex]\frac{26}{39} = \frac{2}{3}[/tex]

[tex]\frac{2}{3} = \frac{2}{3}[/tex]

Hence, after verification, we can get the answer: x = 14.

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

b) To find the perimeter of △QRS, all we have to do is to add all the lengths of the sides of △QRS together.

Hence, 2(14) - 2 + 13 + 17 + 21

= 28 - 2 + 13 + 17 + 21

= 77 units

Therefore, the perimeter of △QRS is 77 units.

Hope this helped!

Answer:

x = 12

Step-by-step explanation:

5x - 30 = 2x + 6

3x = 36

x = 12

Answer:

x=12

Step-by-step explanation:

1) distribute values:

5x-30=2x+6

2) add 30 to both sides

5x=2x+36

3) subtract 2x from both sides

3x=36

4) divide by 3

x=12

Answer:

the answer is c

Step-by-step explanation:

Answer:

Yes, Sample information does indicate that a 2-liter bottle of Pepsi contains more than 250 calories  

Step-by-step explanation:  

Null Hypothesis [H0] : u < 250  

Alternate Hypothesis [H1] : u > 250 {One Tail}  

t = (x' - u) / [ sd / √n ]  

= (255 - 250) / (5.6 / √20)  

5 / (5.6 /√20)  

= 3.99  

As t ie 3.99 > t value 1.65 ie for one tail 95% confidence level. So, we reject the null hypothesis & conclude that it contains more than 250 calories.  

Answer:

if you Simplify the expression it is 112x

(or 120-8x if 30x 24 is multiplication)

Answer: D

Step-by-step explanation:

The best use of the associative and commutative properties to simplify the expression 2.4 + 13 - 5 + 3.6 + 7 would be:

D. (2.4 + 3.6) + [13 + 7 + (-5)]

By applying the associative property, we can group the numbers in a way that allows for easier computation.

Here, we group 2.4 and 3.6 together and 13, 7, and -5 together. This allows us to simplify each group separately and then add the results together.

Calculating the groups:

(2.4 + 3.6) = 6

[13 + 7 + (-5)] = 15

Now, we add the results together:

6 + 15 = 21

So, the simplified expression is 21. Therefore, option D provides the best use of the associative and commutative properties to simplify the given expression.
