I believe the answer is b. There are several ways to find the answer. what I did was I just counted it out in my head AKA the long way..
(1) 2/3 then
(2) 4/3 which is 1 and 1 /3
(3) 6/3 which is 2 cups
(4) 8/3 which is 2 and 2/3
(5) 10/3 which is 3 and 1/3
(6) 12/3 which is 4
(7) 14/3 which is 4 and 1/3
(8) 16/3 which is 5 and 2/3
(9) 18/3 which is 6

another way to do it would be 6x3=18.. 18/2=9 i just like to double check myself

There are 100 teachers in a school. 60 teach science, 25 teach humanities, 15 teach both science and humanities. Find the number
UkoKoshka [18]

Answer:

15

Step-by-step explanation:

The total number of teachers in the school is 100.

The number who teach Science is 60

The who teach humanities is 25.

The number that teach both humanities and Science is 15.

We want to find the number who teach Science but not Humanities.

We obtain this by subtracting the number of teachers who teach both subjects from the number that teach Science.

= 60 - 15 = 45

Therefore 25 teaches science but not Humanities

What is the answer for 4x+y=0
leva [86]
Y=-4x because all you have to do is move the variable to the right by adding its opposite to both sides. So 4x+y-4x=0-4x. Then eliminate the opposites y=0-4x

The side of rhombus is 14 in. The obtuse angle is 160º. Find the longer diagonal of the rhombus.
Mandarinka [93]

Answer:

x = 27.57 in to the nearest hundredth.

Step-by-step explanation:

The longer diagonal  is opposite the obtuse angle.

Also as it is a rhombus all sides = 14 in.

Use the Cosine Rule:

x^2 = 14^2 + 14^2 - 2*14^2 cos 160

x^2 =  760.36

x = sqrt 760.36

x = 27.57 in.
