Answer: Because Knowing only side-side-angle (SSA) does not work because the unknown side could be located in two different places. Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles.The AS.S Postulate does not exist because an angle and two sides does not guarantee that two triangles are congruent. If two triangles have two congruent sides and a congruent non included angle, then triangles are NOT NECESSARILY congruent. And The SSA (or AS.S) combination deals with two sides and the non-included angle. This combination is humorously referred to as the "Donkey Theorem". SS.A (or AS.S) is NOT a universal method to prove triangles congruent since it cannot guarantee that the shapes of the triangles formed will always be the same.

Answer:

The percent decrease was of 32%.

Step-by-step explanation:

The percent decrease is the decrease multiplied by 100, and divided by the initial value.

Rowena’s monthly gasoline bill dropped from $83.75 last month to $56.95 this month.

So a decrease of 83.75 - 56.95 = $26.80

Percent decrease:

26.80*100/83.75 = 32%

The percent decrease was of 32%.

Answer:

24 - X = 10

Step-by-step explanation:

Given that Mai's water bottle had 24 ounces in it. After she drank x ounces of water, there were 10 ounces left, in order to determine the equation that represents this situation, the following reasoning has to be made:

Since the bottle has 24 ounces of liquid, that is its initial content, from which an amount X is subtracted, after which 10 ounces of water remain. That is, 24 - X = 10.

Thus, this equation is solved in the following way:

24 - X = 10

24 = 10 + X

24 - 10 = X

14 = X

The time taken will be "0.5 seconds".

According to the question,

By using Newton's equation,

→                     [tex]s = ut+\frac{1}{2}gt^2[/tex]

Substituting the values,

                    [tex]48=88t+0.5\times 32\times t^2[/tex]

[tex]16t^2+886-48=0[/tex]

                       [tex]t = 0.5 \ seconds[/tex]

Answer:

The cost per pound of the ham is $5.89.

Step-by-step explanation:

Given that a 4kg ham cost $13/kg, in order to find the cost per pound the following calculation has to be made:

1 kg = 2.20462 pounds

2.20462 = 13

1 = X

((1 x 13) / 2.20462) = X

13 / 2.20462 = X

5.89 = X

Therefore, the cost per pound of the ham is $5.89.

Answer:

Step-by-step explanation:

The right triangles are similar, so angle 1 is congruent to the given angle, and angles 3 and 5 are complements of that.

Angles 2 and 4 are the supplements of angles 1 and 5, respectively.

  ∠1 = 35°

  ∠2 = 180° -35° = 145°

  ∠3 = ∠5 = 90° -35° = 55°

  ∠4 = 180° -55° = 125°

Solution :

It is given that we use CI = 95%

Therefore, the value of z = 1.96 as the [tex]$P(-1.96 <z<1.96)=0.95$[/tex]

Also, here it is given that E = 0.05 and the value of p = 0.25

Thus from the formula of E, we can find n

[tex]$E= z \times \sqrt{\frac{pq}{n}}[/tex]

[tex]$n= \left(\frac{z}{E}\right)^2 \times p \times q$[/tex]

[tex]$n= \left(\frac{1.96}{0.05}\right)^2 \times 0.25 \times 0.75$[/tex]

Answer:

6. 72 m²

7. 1152 tiles

Step-by-step explanation:

6. Determination of the area of the dance floor.

Length (L) = 9 m

Width (W) = 8 m

Area (A) =?

Area of the floor (rectangle) = L × W

A = 9 × 8

A = 72 m²

Therefore, the area of the dance floor is 72 m²

7. Determination of the number of tiles needed for the dance floor.

We'll begin by converting the dimension of the tile to metre (m). This can be obtained as follow:

100 cm = 1 m

Therefore,

25 cm = 25 cm × 1 m / 100 cm

25 cm = 0.25 m

Thus, the dimension of the tile is 0.25 m by 0.25 m

Next, we shall determine the area of the tile. This can be obtained as follow:

Dimension of tile = 0.25 m by 0.25 m

Area of tile = 0.25 × 0.25

Area of tile = 0.0625 m²

Finally, we shall determine the number of tile needed. This can be obtained as follow:

Area of the floor (Aₔ) = 72 m²

Area of tile (Aₜ) = 0.0625 m²

Number of tile (n) =?

n = Aₔ / Aₜ

n = 72 / 0.0625

n = 1152 tiles

Therefore, the number of tiles needed for the dance floor is 1152 tiles
