Milan is participating in a 4-day cross-country biking challenge. He biked for 48, 51, and 59 miles on the first three days. How many miles does he need to bike on the last day so that his average (mean) is 55 miles per day?

Answer:

[tex]36[\cos{127^\circ}+i\sin{127^\circ}][/tex]

Step-by-step explanation:

Polar form:  [tex]z=r(\cos(\theta)+i\sin(\theta)[/tex]

To multiply two complex numbers in polar form, multiply the r values and add the angles.

[tex]w_1w_2=36\left[\cos{(95^\circ+32^\circ)}+i\sin{(95^\circ+32^\circ)}\right]\\\\=36[\cos{127^\circ}+i\sin{127^\circ}][/tex]

Answer:

11

Step-by-step explanation:

All angles on a triangle equal 180. 80+60=140.

Now to solve for x, we set it to equal 40 for 180-140.

40=3x+7. 40-7=33

33=3x 33/3=11

x=11

Answer:

B

Step-by-step explanation:

Answer:

Y = 28.31

Z = 13.29

Angle A = 28

Step-by-step explanation:

For Angle A:

Remember a triangle has a total of 180 degree angles. So set up your formula as

180 - 62 -90 = Angle A

For Y:

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.  

sin (B) = opp/hyp or b/c or (y)

sinB = 62

b = 25

Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31

For Z:

Use the Pythagorean theorem to find the unknown side.

[tex]z^{2} = 28.31^{2} - 25^{2}[/tex]

z = 13.29

Answer: 601 square inches

meaning 3 stands for 33 and 37,

good luck! ;)

Answer:

558 weeks

Step-by-step explanation:

let x = number of weeks

this equation can be derived from the question

2 + 1x = 560

collect like terms

x = 560 - 2

x = 558

Answer:

1.1

Answer:

96 tiles

Step-by-step explanation:

The kitchen floor is rectangular on shape.

The dimensions of the kitchen floor were 8 feet by 12 feet.

Hence, Area of a rectangle = Length × Width

Length = 8ft

Width = 12ft

Hence:

Area = 8ft × 12ft

= 96 ft²

If each tile was 1 square foot, the number of tiles he would need is

1 ft² = 1 tile

96 ft² = x

Cross Multiply

1ft² × x = 96 ft² × 1 tile

x = 96 ft² × 1 tile/1 ft²

x = 96 tiles

Therefore, Mark's father would need 96 tiles

Answer:

The answer is 65.97 yd^3

Step-by-step explanation:

The volume of a cone is: v = [tex]\pi r^{2}\frac{h}{3}[/tex]

So, v = [tex]\pi[/tex](3^2)(7/3) = 65.97345 yd^3

Answer:

5x2+6x-6=0

Step-by-step explanation:

Standard form is ax2+bx+c=0

We add 6x to both sides and we get:

5x2+6x-6=0

Got a 100% on edge quiz

Answer: 59049 or 4.64

Step-by-step explanation: 59049 is the answer to 3^sqrt(100), but I wasn't totally sure if you meant ^3sqrt(100) or not so I solved both.

3^sqrt(100) = 59048

^3sqrt(100) = 4.64158

sheeeeeeesh thats alota math

Step-by-step explanation:

Answer:

51 degrees

Step-by-step explanation:

All right angles are 90 degrees and all triangles interior angles add up to 180.

Answer:

5/44

Step-by-step explanation:

3 plus 4 plus 5 is 12 so for a white it is 4/12 or 1/3

then you take out the white baseball and you want a green which is 5/11 3 red 3 white 5 green

5/11 times 1/3 is 5/33

so the odds of picking both is 5/33

Answer:

Step-by-step explanation:

[tex] \sqrt{81 \times 25 \times 4} [/tex]

Since,

[tex] \sqrt{a \times b \times c} = \sqrt{a} \times \sqrt{b} \times \sqrt{c} [/tex]

Hence,

[tex] = \sqrt{81} \times \sqrt{25} \times \sqrt{4} [/tex]

= 9 × 5 × 2

= 90 (Ans)

Answer:

[tex]\sqrt{81*25*4} =90[/tex]
