Time spent with paul : 1/8 h
Total time spent chatting with friends: 2/3h+1/4h=11/12 h

The fraction of the time she spent with paul is (time spent with paul)/(total time spent chatting)

 hence the fraction spent with paul is  (1/8)/(11/12)=3/11

Answer:

2/3 = 16/24

1/4 = 6/24

1/8 = 3/24

(3/24) / (25/24)

(3/24) * (24/25) = 72/600 = 12/100 = 3/25

100 * (1/8)/ (8/12+3/12)

= 100 * (1/8) / (11/12)

= 100 * (3/24)(22/24)

= 100 (3/22)

= 13.6%

-3x^{2}-21x-54 what are the zeros? (Solutions)
Irina-Kira [14]
The only way to solve if it is equal to something
assuming that the teacher wanted you to make it equal to zero do
0=-3x^2-21x-54

remember if we can do
xy=0 then assume x and y=0

so factor

0=-3x^2-21x-54
undistribute the -3
0=-3(x^2+7x+18)
remember 0 times anything=0 so
x^2+7x+18 must equal zero
use quadratice formula which is

if you have
ax^2+bx+c=0 then
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

x^2+7x+18
a=1
b=7
c=18

x=\frac{-7+/- \sqrt{7^{2}-4(1)(18)} }{2(1)}
x=\frac{-7+/- \sqrt{49-72} }{2}
x=\frac{-7+/- \sqrt{-23} }{2}
i=√-1
x=\frac{-7+/- i\sqrt{23} }{2}



the zerose would be
x=\frac{-7+ i\sqrt{23} }{2} or \frac{-7- i\sqrt{23} }{2}

Simplify this problem
Helga [31]

Answer:

c^2 +17c -5

Step-by-step explanation:

I like to line them up vertically

2c^2 +7c - 1

- (c^2 -10c+4)

----------------------

Distribute the minus sign

2c^2 +7c - 1

- c^2 +10c-4

----------------------

c^2 +17c -5

sladkih [1.3K]

Answer:

A = P(1 +\frac{r}{n} )^{nt}

A = 3000(1 + .06/12)^120

strange the question did not want you to calculate the amount

that was given....

the interest is 5,458.19 - 3000 = 2,458.19
