Change the fractions to have like denominators. 16/4 - 12/3 is the same as 48/12 - 48/12 which equals 0. You could also simplify the original fractions and then subtract. 16/4 is 4 and 12/3 is 4 → 4 - 4 = 0

Which expression gives the area of the triangle shown below?
kvasek [131]
The answer is d. The reason this is the answer is because to find the area of a triangle you will find half of the base times the height. The formula looks like this: A=1/2bh.

On this picture the base is the length of the bottom part of the triangle (c). It is the distance of the solid line only.

The height is represented as the straight line that is perpendicular to the base (forms a right/90 degree angle). X is the height of the triangle.

Therefore, 1/2cx is the answer.

Help.me its urgent<br>Find the total surface area and volum of given prism​
Marat540 [252]

Answer:

Total surface area = 434 cm²

Total volume = 470 cm³

Step-by-step explanation:

1. The prism can be decomposed into two rectangular prisms which are the bigger rectangular prism and the smaller rectangular prism

✔️Total surface area of the prism = (surface area of the bigger prism - area of the face joined to the smaller prism) + (surface area of the smaller prism - area of the face joined to the bigger prism)

Surface Area of bigger prism = 2(LW + LH + HW)

L = 10 cm

H = 8 cm

W = 9 - 5 = 4 cm

Area of bigger rectangular prism = 2(10*4 + 10*8 + 8*4)

= 304 cm²

Surface area of the smaller prism = 2(LW + LH + HW)

L = 10 cm

H = 3 cm

W = 5 cm

Area of bigger rectangular prism = 2(10*5 + 10*3 + 3*5)

= 190 cm²

Area of the face joining both rectangular prisms = L*W

L = 10 cm

W = 3 cm

Area = 10*3 = 30 cm²

✅total surface area of the prism = (304 - 30) + (190 - 30) = 274 + 160 = 434 cm²

2. Volume of the prism = volume of the bigger rectangular prism + volume of the smaller rectangular prism

✔️Volume of the bigger rectangular prism = L*W*H

L = 10 cm

H = 8 cm

W = 9 - 5 = 4 cm

Volume = 10*8*4 = 320 cm³

✔️✔️Volume of the bigger rectangular prism = L*W*H

L = 10 cm

H = 3 cm

W = 5 cm

Volume = 10*3*5 = 150 cm³

✅Total Volume of the prism = 320 + 150 = 470 cm³

The radius of a regular decagon, a 10-sided figure, is 15 units. The length of one side of the polygon measures about 9.3 units.
melamori03 [73]
The formula for solving the area of a regular decagon is shown below:
A=(5/2)a²√(5+2√5)
 
where "a" refers to the measurement of the side on which in this problem, it is equal to 9.3 units

We can proceed in solving for the area and the solution is shown below:
A=(5/2)*(9.3)²√(5+2√5)
A=665.47 square units

The answer is 665.47 square units.
