How many 2/3 cups can go into 9 cups

Mathematics
1 answer:
asambeis [7]3 years ago
3 0

Hello there! :D

Today we're gonna learn some math, whoopie!

Alright, so we want to know how many 2/3 cups can go into 9 cups!

Firstly, I want to turn 9 cups into a fraction with the denominator of 3.

Let me do it all fancy for you:

9=\frac{x}{3}

We know we want the denominator to be three, now we just need to do the opposite action (multiplication) to the other side to find what "x" is!

9*3= \frac{x}{3}*3

If you have trouble understanding that step, let me know!

x=27

Enter that into the fraction and we have:

\frac{27}{3}

Notice that 27 is not an even number!

Now, we can the numerator of 27/3s and divide it by the numerator of 2/3s.

27/2=13.5

This is not a whole answer, but the question is asking how many 2/3 cups can go into nine cups. Half of a 2/3 cup does not equal a 2/3 cup, so the answer would be 13 cups.

I hope this helps you can you have a wonderful day,

Kai xx

Divide both sides by -3.

x=91

I hope this helps!

Please help answer these questions. My teacher said they were really easy but I just don't understand. Will mark brainliest !!!
kodGreya [7K]

Answer:

1.  A = 59

2.  A = 43

Step-by-step explanation:

If we have a right triangle  we can use sin, cos and tan.

sin = opp/ hypotenuse

cos= adjacent/ hypotenuse

tan = opposite/ adjacent


For the first problem, we know the opposite and adjacent sides to angle A

tan A = opposite/ adjacent

tan A = 8.8 / 5.2

Take the inverse of each side

tan ^-1 tan A = tan ^-1 (8.8/5.2)

A = 59.42077313

To the nearest degree

A = 59 degrees


For the second problem, we know the  adjacent side and the hypotenuse to angle A

cos A = adjacent/hypotenuse

cos A = 15.3/21

Take the inverse of each side

cos ^-1 cos A = cos ^-1 (15.3/21)

A = 43.23323481

To the nearest degree

A = 43 degrees

Which of the following is NOT true about the following equation. y= -4​
Alex Ar [27]

Answer:

Answer is D.

Step-by-step explanation:

Which is not true?

So, lets assess the answers given to the question.

A. It is the equation of a horizontal line.

Yes, it is. Since there is only one y - value which is y = -4, we can confirm this is the y intercept, so therefore the x value is zero. But it's not the answer we're looking for.

B. It's slope is zero, yes the slope is zero. It only lists the y-intercept which confirms that the slope is 0.

C. Yes, I mean i can't really explain how. Just use desmos calculator, the graph is exactly perpendicular.

D. The line actually does cross the x-axis, -4 is the y intercept and the x value is 0, and zero is still a point. So D is the one which isn't correct making it the correct answer.
