Answer:

(A) 9{\times}h cubic units.

Step-by-step explanation:

From the given figure, the dimensions of the cube is h{\times}3{\times}3

Now, the volume of the cube is given as:

V=(side){\times}(side){\times}(side)

V=h{\times}3{\times}3

V=9{\times}h

V=9{\times}h cubic units

therefore, the volume of the cube is 9{\times}h cubic units.

Hence, option A is correct.

Volume of the cube = a*b*c

Because one of the sides a=h, and two others b=3, and c=3,

we have to write.

V=3*3*h = 9h


Answer: A. 9h.

Find the compound interest compounded annually on rupees 2700 rate 6 ⅔% per annum and time is 2 years​
dalvyx [7]

<u>Answer:</u>

plz mark me as brainliest ...TOOK ME LONG TIME TO TYPE

answer = CI = 3108 RUPEES

<u>Step-by-step explanation:</u>

i am doing the method in which u find the simple interest of first year then second year.

SI FOR 1ST YEAR= P X R X T / 100

SI = 2700 X 20 X 2 / 3 X 100   ( RATE OF INTEREST IS 20 / 3)

SI = 108000/300

SI = 360

SI FOR SECOND YEAR =

P = 2700 + 360= 3060

SI = 3060 X 20 X 2 / 300

SI= 122400 / 300

SI = 408

COMPOUND INTEREST (CI) = PRINCIPLE + SI OF 2ND YEAR

CI = 2700 + 408

CI = 3108 RUPEES

or u can solve be the method

CI = amount - principle

Amount= principle x (change in ratio) raised to time

the excursion boat on the river takes 2 1/2 hours to make the trip to a point 12 miles up stream and to return. If the rate at w
MissTica
Let V, be the rate in still water and let C = rate river current
If the boat is going :
upstream, its rate is V-C and if going 
downstream, its rate is V+C,
But V = 5C, then
Upstream Rate: 5C - C = 4 C
Downstream rate: 5C+C = 6C

Time = distance/Rate,  (or time = distance/speed) , then:
Upstream time 12/4C and
Downstream time: 12/.6C

Upstream time +downstream time:= 2h30 ' then:

12/4C + 12/.6C = 2.5 hours
3/C + 2/C = 5/2 (2.5 h = 5/2)
Reduce to same denominator :
 5C = 10 and Rate of the current = 2 mi/h

y=1/3x-1

We know straight away that the y intercept is -1 from the equation.

y-intercept: (0,-1)

To find the x intercept plug in 0 for y in the equation.

y=1/3x-1

0=1/3x-1

1/3x=1

x=3

x-intercept: (3,0)

answers: y-intercept: (0,-1) and x-intercept: (3,0)
