Answer:

PAGE 1

A. Since PEMDAS 2*3 first

2*3 = 6

then 8/2

8/2 = 4

leaving

11 + 7 - 6 + 4

next 11 + 7

11 + 7 = 18

18 - 6 + 4

18 - 6 = 12

12 + 4 = 16

your answer is 16

B. No because John did not complete his problem correctly. The right answer is 16.

PAGE 2

A. Because of PEMDAS 4 * 12 first

4 * 12 = 48

then 48/3 = 16

your equation comes to

48 + 16 -15

then do

48 + 16 = 64

64 - 15 = 49

the answer is 49

B. If you don't do PEMDAS it can cost you the right answer.

See what answer you get when you don't do PEMDAS and just complete the equation left to right

48 + 4 = 52

52 * 12 = 624

624/3 = 208

208 - 15 = 193

the wrong non-PEMDAS used answer would then be 193

hope this helps:)

Suppose f varies directly as g, and f varies inversely as h. Find g when f = 10 and h = –12, if g = 56 when h = –2 and f = –7. R
kow [346]

Answer:

-480

Step-by-step explanation:

If f varies directly as g, and inversely as h, then we can write the variation equation:

f=\frac{kg}{h}, where k is the constant of variation.

If g=56 when h=-2 and f=-7, then we substitute these values into the formula to find the value of k.

-7=\frac{k(56)}{-2}

-7\times -2=56k

k=\frac{14}{56}=\frac{1}{4}

The equation now becomes:

f=\frac{g}{4h}

if f=10 and h=-12, then;

10=\frac{g}{-48}

g=-48\times 10=-480

The correct answer is B.

Help appreciated !!!!
sergiy2304 [10]

Answer:

Step-by-step explanation:

The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.

   So,

        P(red) = \frac{1}{5}\\\\P(green) = \frac{1}{5}\\\\

   Probability of not blue = 1 - Probability of blue

                                      = 1 - P(blue)\\\\=1 - \frac{1}{5}\\\\= \frac{4}{5}
