-12x - 0.4 > 0.2(36.5x + 80) - 55    Remove the brackets.

-12x - 0.4 > 7.3x + 16 - 55               Combine the like terms on the right

-12x - 0.4 > 7.3x - 39                      Add 12x to both sides

- 0.4 > 7.3x + 12x - 39    

- 0.4 > 19.3x - 39                            Add 39 to both sides.

-0.4 + 39 > 19.3x                              Combine like terms on the left

38.6 > 19.3x                                    Divide by 19.3

38.6 / 19.3 > x

2 > x

Coin Toss A coin is tossed upward with an initial velocity of 32 feet per second from a height of 16 feet above the ground.
AleksAgata [21]

Answer:

The object ever reach a height of 32  feet in 1 second

Step-by-step explanation:

The equation giving the object’s height : h = 16 + 32t -16t^2

Where h = object’s height

t = time

We are supposed to find Does the object ever reach a height of 32  feet

Substitute h = 32 in equation

32 = 16 + 32t -16t^2

32-16= 32t -16t^2

16= 32t -16t^2

1=2t-t^2

t^2-2t+1=0

t^2-t-t+1=0

t(t-1)-(t-1)=0

(t-1)(t-1)=0

t=1,1

So, The object ever reach a height of 32  feet in 1 second

Ella wants to make a fruit salad for herself and 5 friends.
vfiekz [6]
1. I believe she would have 15 cups of fruit salad because it’s 5 cups of grapes, 6 cups strawberries(1 pint = 2 cups which means 6 cups of strawberries) and 4 cups of watermelon (1 pint = 4 cups
2. Since there are 15 cups of fruit salad you would need to divide 15 by the number of friends which would make it 2.5 cups of fruit salad per person

Geoffery went on a trip across South America. He took 1,750 US dollars (USD) with him. In Chile, he traded his money for Chilean
musickatia [10]
Given:
$1,750
Rate = $1 = CLP 496.50
Spent : 217,513 pesos
Rate = CLP 1 = VEF 0.1283
Spent : 38,422.19 bolivars
Rate = VEF 1 = PGY1063.95 
Spent : 12,857,441.39 guarani
Rate = PYG 1 = $0.00002186

$1750 * CLP 496.50 = CLP 868,875
CLP 868,875 - 217,513 = CLP 651,362

CLP 651,362 * VEF 0.1283 = VEF 83,569.7446
VEF 83,569.7446 - 38,422.19 = VEF 45,147.5546

VEF 45,147.5546 * PYG 1063.95 = PYG 48,034,740.70
PYG 48,034,740.70 - 12,857,441.39 = PYG 35,177,299.30

PYG 35,177,299.30 * $0.00002186 = $768.976763 ⇒ $768.98

What is the volume of the cylinder
lora16 [44]

Answer:

C: 9076.3 cm^3

Step-by-step explanation:

Use the formula for the volume of a cylinder.

V=πr^2 times h

h=25

Here, I'm assuming 21.5 cm is the diameter, so divide 21.5 cm by 2 to get 10.75 as r.

V=(10.75^2)π times 25

115.5625π times 25

This is about 2889π

This simplifies best to choice C, which is about 9076.3 cm^3

However, if I was wrong about 21.5 cm being the diameter, my answer is wrong. If 21.5 cm is r, choice D is the correct answer. If 21.5 cm is the diameter, C is the answer.
