1300 = 1000 (1.08)^t
1.3 = (1.08)^t
log base 1.08 (1.3) = t
3.41 = t

Whats the lcd of 1/7,14/17,12/13,5/6

gizmo_the_mogwai [7]

LCD (1/7, 14/7, 12/13, 5/6)

LCM = (7, 7, 13, 6)

= 2 * 3 * 7 * 13

= 546

1/7 = 78/546

14/7 = 1092/546

12/13 = 504/546

5/6 = 455/546

Calculation:

1/7 + 14/7

= 1 + 14/7

= 15/7

The common denominator you can calculate as the least common multiple of the both denominators: LCM (7, 7) = 7

Add:

15/7 + 12/13

= 15 . 13/7. 13 + 12 . 7/13 . 7

= 195/91 + 84/91

= 195 + 84/91

= 279/91

The common denominator you can calculate as the least common multiple of the both denominators: LCM (7, 13) = 91

Add:

279/91 + 5/6

= 279 . 6/91 . 6 + 5 . 91/6. 91

= 1674/546 + 455/546

= 1674 + 455/546

= 2129/546

The common denominator you can calculate as the least common multiple of the both denominators: LCM (91, 6) = 546

Hence, 546 is the LCM/LCD of (1/7, 14/17, 13/13, 5/6).

Hope that helps!!!!!!

Part 2: describe the shape of your cross section of a slice of banana at 45° angle to a space draw picture of the sheep. Part 3:

xenn [34]

Answer:

Part 2:

The shape of a banana cut in 45° angle is that of a curve that is closed with the appearance of a flattened circle or an oval similar to an ellipse therefore having two focal points

The drawing of the angle cross section of a cylinder representing the banana is attached

Part 3:

When the banana is cut in half, perpendicular to the base of the banana, the shape formed is circular withe the center of the banana being about the same location as the center of the circle

The drawing of the perpendicular cross section of a cylinder representing the banana is

If a package of corn chips weighs 1.2 ounces what is the weight in ounces of 48 packages ?

Naya [18.7K]

I'm not usually good at these questions but you can get a calculator that does weight multiplied by units.
so with your question it would be :

1.2 ounces x (48 units)
= 57.6 ounces

57.6 ounces
