Help me please im beggingggg

Answer: <u>96</u> sq ft.

Step-by-step explanation:

First, we will find the area of the rectangular sides. Since the triangle is an equilateral triangle, all the rectangles will be the same size.

A = L * W

A = (10 ft) * (3 ft)

A = 30 ft²

30 ft² * 3 = 90 ft²

Next, we will find the area of the two triangles.

A = $\frac{b*h}{2}$

A = $\frac{3*2}{2}=\frac{6}{2} =3$

3 ft + 3 ft = 6 ft²

Lastly, we will add them together for the total surface area.

90 ft² + 6 ft² = 96 ft²

Calculate the volume of each geometric shape:

pav-90 [236]

Answer:

a) 235.62in³

b) 904.78in³

Step-by-step explanation:

a) The formula to find the volume of a cylinder is:

$V = \pi r^2h$

We are given that r = 5 and h = 3, so we can just plug in and solve:

$V = \pi(5)^2(3) = 235.62in^3$

b) The formula to find the volume of a sphere is:

$V = \frac{4}{3}\pi r^3$

We are given that the diameter is 12in, which means that the radius (r) must be 6in (half the diameter). Now, we can plug in and solve:

$V = \frac{4}{3}\pi (6)^3 = 904.78in^3$

Select the correct answer.<br> Simplify the expression.

gregori [183]

Answer:

Option D :- $\sf \: 18 {x}^{2} {y}^{2} \sqrt[3]{3 {xy}^{2} }$

Step-by-step explanation:

$\sf \: 3x\sqrt[3]{648 {x}^{4} {y}^{8} }$

transform the equation

$\rightarrow \sf \: 3x\sqrt[3]{ {6}^{3} \times {3x}^{2} \times {xy}^{6} \times {y}^{2} }$

rewrite the expression

$\rightarrow \sf \: 3x \times \sqrt[3]{ {6}^{3}} \times\sqrt[3]{ {3x}^{2}} \times \sqrt[3]{ {xy}^{6} } \times \sqrt[3]{{y}^{2} }$

Simplify the radical expression

$\rightarrow \sf \: 3x \times {6xy}^{2} \sqrt[3]{3xy {}^{2} }$

Multiply

$\sf \: 18 {x}^{2} {y}^{2} \sqrt[3]{3 {xy}^{2} }$

There are 161 calories in 28 grams you eat 9 cashews totaling 12 grams. How many cashews are in one serving

makkiz [27]

Answer:

For every 4 grams there are 3 cashews.

12g=9. So that means there are 18 cashews in 24 grams. And like we said, there are 3 cashews in every 4 grams. So there are 21 cashews for 161 cals, equating to 28g.
