becomes

3x^2-7x+2 -2x^2+4x-5

adding

3x^2-2x^2 -7x+4x +2-5

which is

Hassan sells fruit and vegetables at the market.
Juli2301 [7.4K]

Answer: 950 kg

Step-by-step explanation:

Given

Hassan sells a total of 1.33\ \text{tonnes} of vegetables

The ratio of the mass of fruit to the vegetables is 5:7

Suppose x\ \text{tonnes} is the total mass of stuff

For vegetables, we can write

\Rightarrow x\times \dfrac{7}{5+7}=1.33\\\\\Rightarrow x=1.33\times \dfrac{12}{7}=2.28\ \text{tonnes}

For fruits

\Rightarrow 2.28\times \dfrac{5}{5+7}=0.95\ \text{tonnes}\approx 950\ kg

Find the total area for the pyramid with the equilateral base.<br><br><br><br> T. A. =
iogann1982 [59]

Answer:

36√3 + 144

Step-by-step explanation:

Given that,

base of the pyramid is an equilateral triangle with sides = 12

Formula to calculate total surface area of pyramid

<h3>[Base Area] +  1/2 × Perimeter × [Slant Length]</h3>

Base Area

1/2 (height) (base)

1/2 (√12²-6²)(12)

6(6√3)

36√3

perimeter of base

sum of all sides = 12 + 12+ 12

                          = 36

slant height = √10²-6²

                     = 8

put all these values in the formula above

36√3 + 1/2(36)(8)

36√3 + 144

Total area for the pyramid with the equilateral base =

36√3 + 144

What is the surface area of the square pyramid?
wel
Ok to start you need to break this into a net in your head. Next, calculate each triangle
(6*7)/2 = 21
Then, multiply each triangle by the amount of them.
21*4 = 84
Next, get the area of the square.
7*7 = 49
Lastly, add the triangles and the square up.
49 + 84 = 133
