Answer:

51 degrees

Step-by-step explanation:

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

39+90=129

180-129=51

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]

Answer:

They are 24, 692 feet aprart

Step-by-step explanation:

Let us assume at the instance we are measuring their position, that Pluto is at the highest point in the air, which is = 24,568 feet, and Goofy is at the lowest point of the sea (that he can go) = 124 feet.

Before we can proceed with the addition, we need to establish a datum, which will serve as the reference point from which the two distances are measured. This definitely is the sea level, because altitude and depth are usually measured above and below sea level.

Pluto's location to the sea level = 24,568 feet

Goofy's Location to the sea level = 124 feet

their distance apart = 24,568 feet + 124 feet =24, 692 feet apart

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]

Step-by-step explanation:

If they both added the same amount of yellow dye, than blue will determine how dark their icing is. Since Mariana added less blue, her dye will be lighter!

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:

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:

Step-by-step explanation:

Perimeter= all sides added together

so in this case

3x+1 = 2x + 2x + x-1 + x+2 + x-1 + x + 2

now you may be wondering why i put two 2x's, two 2+x, and two x-1  , the far left side is 2x and has 2 lines and so does the bottom side which has 2 lines so theyre congruent ( the same case for the 2+x and x-1 )  so you need to account for all sides.

so lets simplify this huge equation!

3x+1 = 4x + 1x - 1 + 1x + 2 + 1x - 1 + 1x + 2

3x+1 = 8x - 1 + 2 - 1 + 2

3x + 1 = 8x + 2

-3x on both sides

1 = 5x + 2

-2 on each side

-1 = 5x

x = -1/5

A. -6+2y

Step-by-step explanation:

-2×3-2×(-y)

multiply the numbers

-6-2×(-y)

multiplying two negatives equals a positive

-6+2y

Answer:

a

Step-by-step explanation:

-2×3=-6 -2×-y=2y so you awnser us -6+2y

Answer:

[tex]h = \frac{7}{2} [/tex]

Step-by-step explanation:

1) Divide both sides by -4.

[tex]h = \frac{ - 14}{ - 4} [/tex]

2) Two negative makes a positive.

[tex]h = \frac{14}{4} [/tex]

3) Simplify 14/4 to 7/2.

[tex]h = \frac{7}{2} [/tex]

Therefor, the answer is 7/2.

Answer:

h= -128t

Step-by-step explanation:

- 16t+128t

-256t + 128

B   The rate of change is constant and represents the cyclist's speed of 1120 ft/min

Step-by-step explanation:

The difference is always 1120ft for each minute

6 x -2 = -12

-12 = 3, -4

y = 6x^2 + 3x - 4x - 2

y = 3x(2x + 1) - 2(2x + 1)

(2x + 1) (3x - 2) = 0

2x = -1, 3x = 2

x = -1/2, 2/3

pls give brainliest im trying to level up :))

Answer:

(2x+1)(3x-2)

Step-by-step explanation:

Given :-

We need to factor out the given expression. For that we may use the middle term splitting method. Taking the equation,

[tex]:\implies[/tex] y = 6x² - x - 2

[tex]:\implies[/tex] y = 6x² - 4x + 3x-2

[tex]:\implies[/tex] y = 2x ( 3x -2) +1( 3x -2)

[tex]:\implies[/tex] y = (2x + 1)(3x -2 )

Answer:

probably a 60%

Step-by-step explanation:

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:

60

Step-by-step explanation:

To find the range you subtract the highest and lowest value

The highest value on this graph is 105 from the month of May and the lowest value is 45 from the month of March.

When you do 105-45 you get 60 which is the range

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
