Answer:

V=904.77\ cm^3

Step-by-step explanation:

Given that,

The radius of sphere, r = 6 cm

We need to find the volume of the sphere.

The formula for the volume of a sphere is given by :

V=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\times \pi \times (6)^3\\\\=904.77\ cm^3

So, the volume of the sphere is equal to 904.77\ cm^3.

the states C&D spend a total of 55.6 million dollars for tourism the state C spends 3.2 million dollars more than State D fi
Helga [31]
Alright, let's break this down.
State D blew 55.6 million bucks on tourism.
State C spends an unknown amount, we just know it's 3.2 million MORE than state D.
Well, since we know State D spent 55.6 million on tourism, just add 3.2 million to it to find out how much State C spent.
55.6+3.2=58.8.

This means the state's spent:
State D: 55.6
State C: 58.8

~Hope this helps!

faltersainse [42]

Answer:

x+2y-z=5 ...(1)\\ -x-y+2z=-13...(2) \\ 2x+y-2z=14...(3) \\  \\ add \: (2) + (3) \\\boxed{x= 1} \\ 2 \times (1) + (2) \\ x + 3y =  - 3 \\ 1 + 3y =  - 3 \\ 3y =  - 4 \\ \boxed{y =  -  \frac{4}{3}  }\\ solve \: for \: z \\ x + 2y - z = 5  \\ 1-\frac{4}{3}(2)-z=5\\3-8-3z=15\\3z=-20\\\boxed{z = -   \frac{20}{3} }

Question

Which expressions are less than 7/8? Choose all answers that apply:

a) 7/8 x 9/15

b) 7/8 x 3/4

c) 7/8 x 9/9

d) 7/8 x 4/3 ​

Answer:

a) 7/8 x 9/15

b) 7/8 x 3/4

Step-by-step explanation:

We are asked to find which expression are least than 7/8

Solving 7/8 = 0.875

We would evaluate the given option one after the other.

a) 7/8 x 9/15

= 63/120 = 0.525

b) 7/8 x 3/4

= 21/32 = 0.65625

c) 7/8 x 9/9

= 7/8 × 1 = 7/8 = 0.875

d) 7/8 x 4/3

= 7/6 = 1.1666666667

Therefore, from the above calculation, the expressions are less than 7/8 are

option a) a) 7/8 x 9/15 and b) 7/8 x 3/4
