[tex]\frac{1}{5^{3} }[/tex]

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex] ,  [tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

[tex]5^{-8}[/tex] × [tex]5^{5}[/tex]

= [tex]5^{(-8+5)}[/tex]

= [tex]5^{-3}[/tex]

= [tex]\frac{1}{5^{3} }[/tex]

84 ft^2

Step-by-step explanation:

Rectangle 1: Area = l x w = 3x6=16

Rectangle 2: 4x6= 24

Rectangle 3: 5x6=30

Triangle 1: A = 1/2 b x h = 1/2 x 4 x 3 = 6

Triangle 2: 1/2 x 4 x 3 = 6

Total = 16+24+30+6+6 = 84

Answer:

Both or neither

Step-by-step explanation:

Answer:

  a = 108°

  b = 24°

Step-by-step explanation:

a) The pentagon will have interior angles of 540°/5 = 108°.

 Angle a = 108°

__

b) The reflex angle at a vertex of the pentagon is 360° -108° = 252°. At the obtuse angle of the unshaded triangle, 120° of that amount is take up by two internal angles of the equilateral triangles. Those are 60° each. So, the obtuse angle in the unshaded triangle is ...

  252° -120° = 132°

That triangle is isosceles, so the angle at b is ...

  2b° +132° = 180°

  b = (180 -132)/2 = 48/2 = 24

  Angle b = 24°

Answer:

a = 108 °

b = 24°

Step-by-step explanation:

Answer:

Step-by-step explanation:

1)

a/c =b/d  where a=27 c=30 b=x d=18

27/30 = x/18

27*18/30=x

16.2 = x

2)

a/c =b/d  where a=2x-5 c=x+11 b=16 d=14

2x-5 / x + 11  = 16 / 14

14(2x-5) = 16(x+11)

28x - 70 = 16x + 176

12x = 246

x = 20.5

3)

6+15 / 7+x  = 7 /6

6(6+15) = 7(7+x)

6*21 = 49 +7x

126 = 49 +7x

77 = 7x

11 = x

4)

3*[(x-6)+3]=[tex]6^{2}[/tex]

3(x-3) = 36

3x-9 = 36

3x = 45

x = 15

Answer:

5 seconds

Step-by-step explanation:

When the rocket is on the ground, then h = 0 , that is

- 6t² + 30t = 0 ← factor out - 6t from each term

- 6t(t - 5) = 0

Equate each factor to zero and solve for t

- 6t = 0 ⇒ t = 0 ← when rocket is launched

t - 5 = 0 ⇒ t = 5 ← time when rocket returns to ground

Answer:

B) h = 3V/πr²

B) The speed of the car depends on the distance traveled

Answer:

130

Step-by-step explanation:

? is an exterior angle of a triangle

An exterior angle is equal to the sum of the two opposite interior angles ( 35 and 95 in this case )

That being said the missing angle = 95 + 35

95 + 35 = 130

Hence, the answer is 130

Answer:

130

Step-by-step explanation:

1. We have a triangle and all angles in a triangle sum up to 180, so do 35+95 and then subtract the difference from 180, and you get 50

2. Now we have a linear pair next to 50' on the outside, signifying a linear pair, meaning that both angles should sum up to 180, so 180-50= 130

Have a good and safe day whoever reads this :)

Answer:

Step-by-step explanation:

3(-2)³-2-1 =

-24-3=-27

Answer:

Mel's height is 159cm, her brother's height is 177cm and their grandma's height is 166cm.

Step-by-step explanation:

Let the grandma's height be g cm.

Mel's height= (g -7) cm

Brother's height= (g +11) cm

Total height

= Mel's height +brother's height +grandma's height

= g -7 +g +11 +g

= (3g +4) cm

Given that their total heights is 502 cm,

(3g +4) cm= 502 cm

3g +4= 502

3g= 502 -4 (-4 on both sides)

3g= 498

g= 166 (÷3 on both sides)

To find their heights, substitute g= 166 back into the expressions.

Grandma's height= 166cm

Mel's height

= 166 -7

= 159cm

Brother's height

= 166 +11

= 177cm

Answer: A≈12.57mi²

Step-by-step explanation:

Answer:

A. 12 ≥ w ≥ 33

Step-by-step explanation:

So as wide as 33, means that it could be less than or equal to 33. And as narrow as 12 means greater than or equal to 12, so put that together and we have our answer

if this is wrong let me know so I can fix it

Answer:

B is our answer 12.56

When finding area for circles we do

radius x radius x pi

Since we don't have the radius in the problem we have to figure it out but it wont be so hard knowing that the radius is half of the diameter so 4 ÷ 2 = 2 so 2 is our radius now we need tp square it in easier words multiply by itself so

2 x 2 = 4 then we just do 4 x pi!

So 4 x 3.14 = 12.56 So our answer is 12.56

Hope this helps!

Answer:

The correct option is (b).

Step-by-step explanation:

Given that,

The radius of the circle, r = 8 cm

The area of the sector, [tex]A=56\pi \ cm^2[/tex]

We need to find the measure of the sentral angle. The formula for the area of a sector is given by :

[tex]A=\dfrac{1}{2} r^2\theta[/tex]

Where

[tex]\theta[/tex] is the central angle

Substitute all the values,

[tex]\theta=\dfrac{2A}{r^2}\\\\\theta=\dfrac{2\times 56\pi }{8^2}\\\\\theta=\dfrac{7\pi}{4}\ rad[/tex]

So, the correct option is (b).

Answer:

B

Step-by-step explanation:

Solving with formula of area of circle,B is the correct answer of this question.
