Answer:

Surface area of cube = 6x²

surface area of cube = surface area of sphere

it means that 6x²=4πr²

x²=

\frac{4\pi {r}^{2}  }{6}  =  \frac{4 \pi9}{6}  =  \frac{4\pi3}{2}  = 6\pi

x =   \sqrt{6\pi}

\sqrt{6\pi}  =  \sqrt{k\pi}

6\pi = \pi \: k

k = 6

Answer:

didn't give clear instructions on what to do. I just assumed you add them. answer is down below. :)

Step-by-step explanation:

if ur supposed to add them then

1. 1/8 + 8/8 + 3/8 = 12/8 = 1 1/2

2. 1/4 + 2/4 + 1/4 = 4/4 = 1

3. 1/8 + 8/8 + 4/8 = 1 5/8

4. 1/4 + 1/4 + 2/4 = 4/4 = 1

5. 1/4 + 1/4 + 1/4 + 1/4 = 1

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 45 minutes? In 1 hour?
mina [271]

Answer:

33.75 miles in 45 minutes,

45 miles in an hour

Step-by-step explanation:

45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,

                    1 3/4= 7/4 ---> 7/4*3=5.25

car travels 5.25 miles for every 7 minutes,

45/7*5.25= 33.75 miles

1 hour (60 minutes):

using that the car travels 5.25 miles for every 7 minutes,

60/7*5.25= 45 miles

Hope that makes sense!

8. A triangle has sides with lengths of 6, 8, and 10 units, and a square has a
svet-max [94.6K]

Difference between the area of the triangle and square is 25

Step-by-step explanation:

  • Step 1: Find the area of the triangle given its 3 sides using the Heron's formula.

Area of the triangle = \sqrt{s (s-a)(s-b)(s-c)} where s = \frac{a + b + c}{2}

⇒ s = (6 + 8 + 10)/2 = 24/2 = 12

\sqrt{s(s-a)(s-b)(s-c)} = \sqrt{12(12-6)(12-8)(12-10)}

                                    = \sqrt{12(6)(4)(2)} = \sqrt{576} = 24 sq. units

  • Step 2: Find the area of the square with perimeter = 28 units.

Perimeter of the square = 4 × side = 28

⇒ Side of the square = 28/4 = 7 units

⇒ Area of the square = (side)² = 7² = 49 sq. units

  • Step 3: Find the difference between the area of the square and triangle.

Difference = 49 - 24 = 25
