A + b + c = 12
c = (a + b) - 2.....c - a - b = -2
3a + 1 = 2c

add the first 2 equations
a + b + c = 12
-a - b + c = -2
------------------add
2c = 10
c = 5 <== longest side is 5

sub in 5 for c in the 3rd equation
3a + 1 = 2c
3a + 1 = 2(5)
3a + 1 = 10
3a = 10 - 1
3a = 9
a = 3 <== shortest side

now sub in 5 for c and 3 for a back into the first equation
a + b + c = 12
3 + b + 5 = 12
b + 8 = 12
b = 12 - 8
b = 4 <== other side

If g(x) is a linear function such that g(-3) = 2 and g(1) = -4, find g(7).
SVETLANKA909090 [29]

Answer:

g(x)=f(x)=12x

Step-by-step explanation:

Since f(x)=g(x)  at two points x=−3,−1 , we can tell that g(x)  passes through the two points (−3,-32),(−1,−12)

But if g (x)is linear, that means that its graph is a straight line.

And since there is only one way to draw a straight line through two points, there is only one answer for g(x) , and since f(x) is a straight line passing through those two points as well, g(x)  has to be equal to f(x)

How many cubic centimers of water can this paper cone cup hold?
8090 [49]

Answer:

B: 48π cubic centimeters

Step-by-step explanation:

A: 216π cubic centimeters

B: 48π cubic centimeters

C: 144π cubic centimeters

D: 192π cubic centimeters

Volume of the paper cone cup = 1/3πr²h

Diameter = 8 cm

Radius, r = diameter / 2

= 8 cm / 2

= 4 cm

Height, h = 9 cm

Volume of the paper cone cup = 1/3πr²h

= 1/3 × π × 4² × 9

= 1/3 × π × 16 × 9

= (1 × π × 16 × 9) / 3

= 144π / 3

= 48π cm³

Volume of the paper cone cup = 48π cm³
