The difference between two numbers is 16. Three times the larger number is seven times the smaller. What are the numbers?​
slavikrds [6]

Answer:

12 and 28

Step-by-step explanation:

Represent the numbers using x and y.  Then y - x = 16.  (y is the larger one.)

Then 3y = 7x, and y = (7/3)x.

Substituting (7/3)x for y in y - x = 16, we get:

(7/3)x - x = 16.

Eliminate the fraction by multiplying all three terms by 3:

7x - 3x = 48, or 4x = 48, yielding x = 12.  Then y = (7/3)(12) = 28.

What is the percent increase in the surface area of the AAA battery to the AA battery? Round your answer to the nearest tenth of
Bogdan [553]

Answer:

101.1%

Step-by-step explanation:

The two batteries are in the shape of cylinder.

The total surface area of a cylinder

SA = (2πr^2 + 2πrh ) =

For AAA battery

h = 0.8mm

r = 1.9 mm

SA = (2π(1.9)^2 + 2π × 1.9 × 0.8 )

SA = 22.68 + 9.55

SA = 32.23 mm^2

For AA battery

h = 1 mm

r = 2.75 mm

SA = (2π(2.75)^2 + 2π×2.75× 1 )

SA = 47.52 + 17.28

SA = 64.80 mm^2

Increase in SA = 64.80 - 32.23

Increase in SA = 32.57

% increase = increase in SA/AAA × 100

% increase in SA = 32.57/32.23 × 100

% increase in SA = 101.1%

There are 6 people on the board of supervisors for
Sergio [31]

Answer:

40 ways

Step-by-step explanation:

Step one:

given data

number of people= 6

number of committees=6

Required

The number of ways the committees can be formed differently

Step two:

Applying the combination formula we have

C(n,r)= n!/(n-r)r!

substitute

C(n,r)= 6!/(6-3)3!

C(n,r)= 6*5*4*3!/3*3!

C(n,r)= 6*5*4/3

C(n,r)= 120

/3

C(n,r)= 40 ways
