3. 
The area of a triangle can be given by (just plug and chug as always):
A_t = \frac{1}{2} bh = \frac{1}{2}(3)(4) = 6ft^2
The area of the triangle is 6ft².

4. I will divide into a triangle and a rectangle (because the actual equation for the area of a pentagon requires it to be a perfect pentagon). Let's do the triangle first (height is 3 because you subtract 12 from 15):
A_t = \frac{1}{2} bh = \frac{1}{2}(8)(3) = 12m^2
A_r = bh = 12(8) = 96m^2
Now we just add them:
96+12 = 108m^2

So, the area of that pentagon is 108m².

5. You are actually wrong on this one because the area of a triangle is:
A_t = \frac{1}{2}bh
So, just halve your answer and it will be correct.

6. We can just split it into 4 triangles of equal area and then multiply the area of 1 triangle by 4 to get the total area. Let's do just that:
A_t = \frac{1}{2}bh = \frac{1}{2}(2.5)(5) = 6.25cm^2
Multiply by 4 to get total area:
6.25*4 = 25cm^2

So, the area of the given rhombus is 25cm².

Answer:

x = 47

2x+6 = 100  which is the angle measure

Step-by-step explanation:

The angles are vertical and vertical angles are equal

2x+6 = 100

Subtract 6 from each side

2x+6-6 =100-6

2x = 94

Divide by 2

2x/2 = 94/2

x =47

Now to find the measure of 2x+6

We know that it is equal to 100

so 2x+6 = 100

What is the easiest way to find the answer?
amid [387]

multiply the number of ounces by the price per ounce

Blue jelly beans cost 0.28 per ounce and there are 4 ounces

 4 * 0.28 = 1.12

red jelly beans cost 0.55 per ounce and there is 3 ounces

3 *0.55 = 1.65

now add the totals: 1.12 +1.65 = 2.77

 this is more than the total they want of 2.20

 so it is not reasonable.
