When a ball is bounced on a smooth surface, the angles formed by the path of the ball are congruent. If the path of a ball forms a 53^{\circ} angle with the floor, find \(m \angle A B C\).

According to the Centers for Disease Control and Prevention (CDC), the average shower lasts 8 minutes. If you like to linger in the shower for longer than 15 minutes, you might want to rethink your hygiene routine.

According to board-certified dermatologist Dr. Edidiong Kaminska, MD, the recommended maximum shower time is about 5 to 10 minutes. This is enough time to cleanse and hydrate the skin without overdoing it. “Our skin needs water, just like our bodies, but if we over- or under-do it, then it may have consequences,” she adds.

And if you have dry skin or eczema, Dr. Anna Guanche, MD, FAAD, says shorter, lukewarm showers are recommended. Moreover, the Baylor College of Medicine says it’s especially important to avoid hot showers in the wintery months since the heat can damage the surface of the skin, which can lead to inflammation and increase symptoms of eczema.

Side effects of long showers

While a long, hot shower might seem like the best way to pamper your body, over-showering may dehydrate the skin. “The purpose of showering is to hydrate and cleanse the skin, but warm or hot showering for prolonged periods strips away natural oils of the skin and opens up our pores and allows moisture to escape,” Kaminska says.

To keep moisture in, she usually recommends applying a body moisturizer after showering to the skin since it allows the water (hydration) to stay in the skin and not escape.

The number of windows which can be framed with three 10-foot long pieces of lumber given the dimensions of the windows is; two and a half.

It follows from the task content that the number of windows that can be made given the dimensions of the windows be determined.

On this note, it follows that since the windows are 3 feet high and 3 feet width, the perimeter of each window(square shaped) covered by lumber is;

P = 4s

P = 4 × 3

P = 12 feet.

Hence, each window requires 12 feet of lumber.

However, since the builder has only three 10-foot long pieces of lumber which is equivalent to; 3 × 10 = 30 feet worth.

The number of windows that can be made is;

= 30/12

= 2.5.

Ultimately, only 2 and a half windows can be framed from the three 10-foot long pieces of lumber.

d) 155

Step-by-step explanation:

The value of x is,

→ x = 5

Now the expression is,

→ 6x² + x

Let's solve the expression,

→ 6x² + x

→ 6(5)² + 5

→ 6(25) + 5

→ 150 + 5

Hence, the answer is 155.

Answer:

x=8

Step-by-step explanation:

starts with 0.5x+2=6, so move the constant to the right, 0.5x=6-2, then calculate the right side, 0.5x=4, then divide both sides, and x=8

Answer:

x = 8

Step-by-step explanation:

Get variable on left and constants on right

0.5x = 6 - 2

0.5x = 4

Divide both sides by 0.5

x = 8

Applying the distance formula, the value of a is 2 or -2.

The distance formula is:

d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Given the following:

d = XY = 10 units

X(a - 5, -2a) = (x1, y1)

Y(a + 1, 2a) = (x2, y2)

Plug in the values into the distance formula

10 = √[((a + 1) - (a - 5))² + (2a - (-2a))²]

10 = √[(a + 1 - a + 5)² + (2a + 2a)²]

10 = √(6² + (4a)²)

10 = √(36 + 16a²)

10² = 36 + 16a²

100 = 36 + 16a²

0 = -100 + 36 + 16a²

0 = 16a² - 64

16a² - 64 = 0

Factorize

16(a² - 4) = 0

16(a - 2)(a + 2) = 0

a = 2 or a = -2

Therefore, applying the distance formula, the value of a is 2 or -2.

The equation of line is y = -4

Given the points:

(x₁, y₁) = (-1, -4)

(x₂, y₂) = ( 3, -4)

The slope-intercept form:

y = mx + b

Where, m is the slope and b is the y-intercept, that is (0, b)

The formula for slope:

m = (y₂ – y₁) / (x₂ – x₁)

We have given

x₁ = -1

x₂ = 3

y₁ = -4

y₂ = -4

So,

m = (-4 – (-4)) / (3 – (-1)) = (-4 + 4) / (3 + 1) = 0/4 = 0

Therefore we have the equation of the line as:

y = mx + b

-4 = 0(x) + b

-4 = 0 + b

b = -4

Therefore, the equation of line y = -4

Answer:

1) 256, -128, 64, -32

2) 27, 9, 3, 1, 1/3

3) 5x², 5x⁴, 5x⁶, 5x⁸, 5x¹⁰,

Step-by-step explanation:

1. In this geometric series each term is obtained by multiplying the previous term by (-1/2) or dividing by (-2).

256 ÷ (-2) = - 128

-128 ÷ (-2) = 64

64 ÷ (-2) = (-32)

The geometric series is:

     256, -128, 64, -32...

We can find the common ratio by dividing the second term by first term.

The number of apples in the 12th bag is 9.

There are 12 bags of apples on the market stalls.

The mean number of apples in each bag is 8.

Therefore, the number of apples in the 12th bag can be calculated as follows:

mean = ∑fx / ∑f

Hence,

let the number of apples in the 12th bag = a

mean = 6 × 1 + 7 × 4 + 8 × 2 + 9 × 3 + 10 × 1 + x × 1/ 1 + 4 + 2 + 3 + 1 + 1

mean = 6 + 28 + 16 + 27 + 10 + x / 12

mean = 87 + x / 12

8 = 87 + x / 12
