Answer:

55135 lbs (rounded to the nearest pound)

Step-by-step explanation:

​diameter of tank = 15 ft

Radius = 15/2 =7.5

volume of hemisphere = 2/3 ×π× 7.5³=883.5729

total weight of water = 62.4 × 883.57 = 55134.768

55134.768 rounded to the nearest pound is 55135 lb

Answer:

The answer is (16.538461(repeated), 26.461538(repeated))

Answer:

x=16.538462 and y=26.461538

Answer:

x = 74 degrees

Step-by-step explanation:

If we assume that this triangle is isosceles, then the sum of the two angles at the bottom is (180 - 32) degrees, or 148 degrees.  The angle x is half that, i. e., x = 74 degrees

2x = 20

x = 10

Answer:

45º

Step-by-step explanation:

A triangle always has 180º

C is a right angle which is 90º. Proof is because of the square.

So now we have 90º left and 2 angles left.

90 ÷ 2 = 45

So your answer is 45º

Answer: 37 cm^2

Step-by-step explanation:

Break the shape into two recognizable shapes. In this case a triangle and a square. To find area of a triangle use Area= 1/2 base x height. To find area of a square use Area = length x width. Then add the two together.

The descending values of the numbers is 0.98 > 0.925 > 0.88 > 0.7

Given data ,

Let the numbers be represented as A

Now , the value of A is

A = { 0.98 , 0.925 , 0.88 , 0.7 }

And , arranging in the descending order means from the greatest to the least value

So , the value of A is 0.98 > 0.925 > 0.88 > 0.7

Hence , the descending order is 0.98 > 0.925 > 0.88 > 0.7

Answer:

Area = 9 cm²

Step-by-step explanation:

The shape given is a kite.

Area of a kite = ½(D1*D2)

Where,

D1 = 6 cm

D2 = 3 cm

Therefore:

Area = ½(6*3)

Area = ½(18)

Area = 9 cm²

Step-by-step explanation:

Delta math

According to graph, the coordinates of the vertex of the parabola are (-4,-4).

"A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped."

"The vertex of a parabola is the point at the intersection of the parabola and its line of symmetry. For a parabola whose equation is given in standard form, the vertex will be the minimum (lowest point) of the graph and the maximum (highest point) of the graph.

After analysing the graph, the vertex of the parabola are (-4,-4)
