If you were to solve this equation with fractions with the same denominater, you only need to pay attention to the numerater.


you have 8/5 liters to fill 1/5 containers, 8 goes in to 1 8 times, therefore you can fill the cup eight times.


The answer is 8

Answer:

Step-by-step explanation:

We will use the general area formula for finding the area of triangle when you are given information for SAS, which we have been.

A=\frac{1}{2}absinC , where a and b are the given side lengths and C is the included angle. You can ONLY use this when you have the info for SAS in a triangle. For us,

a = 17, b = 15 and C = 35 degrees.  Filling in:

A=\frac{1}{2}(17)(15)sin35

Do that on your calculator in degree mode and you'll find the area to be

73.1 meters squared

I NEED HELP PLEASE, THANKS

First, find the scale factor.

8.4 / 7 = 1.2

9 / 7.5 = 1.2

7.2 / 6 = 1.2

Since both solids are different sizes, the solids aren't congruent.

The size ratio for all the sides are:

8.4:7

9:7.5

7.2:6

Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent.

Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.

Best of Luck!

Dillon says that 4b and -2b are not like terms
olganol [36]
He is wrong because as long as they have the same terms/ variables behind the number it doesn’t matter about if it is positive or negative

Solve for x in the triangle above
faust18 [17]

Answer:

x = 30

Step-by-step explanation:

The interior angles of a triangle must always add up to 180.

2x + 2x + 3x - 30 = 180

Add 30 to both sides to seperate variables.

2x + 2x + 3x = 210

Combine like terms.

7x = 210

Divide by 7 to isolate x.

x = 30
