Answer:

The answer is √5+√3+10+2√15

Answer: [tex]\sqrt{5} + \sqrt{3} + 10 + 2\sqrt{15}[/tex]

Step-by-step explanation:

[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} }[/tex]

You need to multiply by the conjugate

To find the conjugate, first remember:

(a+b)(a-b) = a^2 - b^2 (if a and b are sqrts, this will eliminate the square roots, rationalizing the denominator)

You have √5 - √3 as the denominator

You should multiply by √5 + √3

(This will eliminate the sqrts)

Remember to multiply both the numerator and denominator

[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } = \frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } * \frac{\sqrt{5}+\sqrt{3} }{\sqrt{5}+\sqrt{3}}[/tex]

Now simplify

[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } * \frac{\sqrt{5}+\sqrt{3} }{\sqrt{5}+\sqrt{3}} = \frac{(2+4\sqrt{5})(\sqrt{5}+\sqrt{3})}{(\sqrt{5}-\sqrt{3})(\sqrt{5}+\sqrt{3})} = \frac{2\sqrt{5}+2\sqrt{3}+20+4\sqrt{15}}{5-3} = \sqrt{5} + \sqrt{3} + 10 + 2\sqrt{15}[/tex]

Answer: 15 oatmeal cookies.

Step-by-step explanation:

There were 25 cookies baked.

Out of these, 3/5 are oatmeal cookies.

The amount of actual oatmeal cookies is:

= fraction of oatmeal cookies * total number of cookies

= 3/5 * 25

= 75 / 5

= 15 oatmeal cookies.

Step-by-step explanation:

the sides of the box are the quartiles, and the dots at the end are the range of the data. the line in the middle of the box is the center of the data.

Answer:

9^2 + x^2 = 12^2

x^2 = 144 - 81

x^2 = 63

x = √63 = 3√7 or 8

Answer:

4 pairs of sock and a little bit of left over change.

Step-by-step explanation:

24.95 + 5.95x = 50

-24.95                -24.95

5.95x=25.05

/5.95   /5.95

x = 4.21

We drop the 0.21 because you cant have 0.21 pairs of socks and we get:

x=4

Answer:

About 4 pairs.

Step-by-step explanation:

50.00-24.95=25.05

5.95x5=29.75 (that is more the 25.05, so no.)

5.95x4=23.80 (Its a little bit less but not higher than the number we have left to spend.)

Answer:

m = 4

Step-by-step explanation:

In order for this equation to be true, the angles must be complementary.

So, 18m- 12 + 7m + 2 = 90

25m - 10 = 90

25m = 100

m = 4

Answer:

The length of the bold arc is approximately 13.4 mi

Step-by-step explanation:

The radius of the circle having the arc, r = 17 mi

Therefore, the circumference of the circle, 'C', is given as follows;

C = 2·π·r

∴ C = 2×π×17 = 34·π

The angle subtended by the arc = 45°

The sum of the angles at the center of the circle = 360°

By similarity, the ratio of the length of the bold arc to the circumference of the circle = The ratio of the angle subtended by the arc to the sum of the angles at the center of the circle

Mathematically, we have;

[tex]\dfrac{The \ arc \ length}{C} = \dfrac{\theta}{360^{\circ}}[/tex]

Therefore, we get;

[tex]\dfrac{The \ arc \ length}{34 \cdot \pi} = \dfrac{45 ^{\circ}}{360 ^{\circ}} = \dfrac{1}{8}[/tex]

[tex]{The \ arc \ length}{} = \dfrac{1}{8} \times 34 \cdot \pi = 4.25 \cdot \pi[/tex]

The length of the bold arc = 4.25·π mi ≈ 13.4 mi (by rounding off the answer to the nearest tenth).

Answer:

0.225989

Step-by-step explanation:

3x+9+x-11=180

4x-3=180

4x=180-3

4x/4x=177/4x

0.225989

Answer:

=78 degrees

Step-by-step explanation:

complementary angles add up to 90 degrees

A + B = 90

3x + 9 + x - 11 = 90

3x + x + 9 - 11 = 90

4x - 2 = 90

collect like valuables

4x = 90 + 2

4x = 92

x =23

angle A = 3x + 9

             = (3 x 23) + 9

             = 69 + 9

             = 78

Answer:

  16 m

Step-by-step explanation:

The useful trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(41°) = a/(25 m)

  a = (25 m)sin(41°) ≈ 16.40 m

The measure of side 'a' is about 16 meters.

Answer:

[tex]Area = 56892in^2[/tex]

Step-by-step explanation:

Given

[tex]\triangle TUV[/tex]

[tex]t = 320in[/tex]

[tex]u = 360in[/tex]

[tex]\angle V = 81^\circ[/tex]

Required

Calculate the area

Given two sides and a middle angle, the area of a triangle is:

[tex]Area = \frac{1}{2}ab*sinC[/tex]

In this case, it is:

[tex]Area = \frac{1}{2}tu*sinV[/tex]

[tex]Area = \frac{1}{2}*320*360*sin(81)[/tex]

[tex]Area = \frac{1}{2}*320*360*0.9877[/tex]

[tex]Area = 56891.52[/tex]

[tex]Area = 56892in^2[/tex] --- approximated
