Answer:

  • <u>1,310 lb</u>

Explanation:

<u>1) Calculate the volume of the water in the tank.</u>

  • Area of the base of the tank: B = 7 ft × 4 ft = 28 ft²
  • Height of the tank: H = 9 in = 9 in × 1 ft / 12 in = 0.75 ft
  • Volume of the tank: V = area of the base × height = B × H = 28 ft² × 0.75 ft = 21 ft³.

<u>2) Calculate the weight of 21 ft³ of water.</u>

Since this is not a chemistry question but a math question, I will not use the fomula of density but set a proportion with one unknown:

  • 62.4 lb / 1 ft³ = x / 21 ft³

Solve for x:

  • x = 21 ft³ × 64 lb / ft³ = 1,310.4 lb.

So, rounding to the next integer, the water in the tank weighs 1,310 pounds, when it is full.

The water in the tank's weigh is 1310.4 pounds/feet³

<h3>Further Explanation</h3>

From the problem above we know that:

The water's weighs = 62.4 pounds/foot³

The tank measurement = 7 ft x 4 ft x 9 inch

<u>First step</u>

We are going to convert the tank's measurement into foot

1 inch = 0.083 foot, so 9 inches would be

9 x 0.083 ft = 0.75 ft

Second step

We are going to find the tank's volume

7 ft x 4 ft x 0.75 ft = 21 feet³

with the proportional calculation we going to find the tank's water weigh when it is full. The tank's water weigh would be in x variable

\frac{water weigh}{volume}  =\frac{62.4 pounds}{1 ft} = \frac{x}{21}

x = 62.4 pounds x 21 feet³ = 1310. 4 pounds

So, the weigh of the water in tank is 1310.4 pounds/feet³

Find the measures of the numbered angles in the isosceles trapezoid.<br> I need help ASP
Novay_Z [31]

Answer:

  ∠1 = 50°

  ∠2 = ∠3 = 130°

Step-by-step explanation:

In an isosceles trapezoid, such as this one, the angles at either end of a base are congruent:

  ∠1 ≅ 50°

  ∠2 ≅ ∠3

The theorems applicable to transversals and parallel lines also apply to the sides joining the parallel bases. In particular, "consecutive interior angles are supplementary." That is, angles 1 and 2 are supplementary, for example.

  ∠2 = 180° -∠1 = 180° -50° = 130°

We already know angle 3 is congruent to this.

  ∠1 = 50°

  ∠2 = ∠3 = 130°

_____

<em>Additional comment</em>

It can be easier to see the congruence of the base angles if you remove the length of the shorter base from both bases. This collapses the figure to an isosceles triangle and makes it obvious that the base angles are congruent.

Alternatively, you can drop an altitude to the longer base from each end of the shorter base. That will create two congruent right triangles at either end of the figure. Those will have congruent corresponding angles.
