Answer:

La inclinación de la Torre de Pisa con respecto al eje vertical es 25.167º.

Step-by-step explanation:

Si tenemos una inclinación de la forma [tex]a^{\circ}\,b'\,c''[/tex] (nótese que ' y '' significan minutos y segundos, respectivamente), podemos expresarlo exclusivamente en grados sexagesimales mediante la siguiente fórmula:

[tex]x = a + \frac{b}{60} + \frac{c}{3600}[/tex] (1)

Si sabemos que [tex]a = 25[/tex], [tex]b = 10[/tex] y [tex]c = 2[/tex], entonces el ángulo expresado exclusivamente en grados sexagesimales:

[tex]x = 25+\frac{10}{60}+\frac{2}{3600}[/tex]

[tex]x = 25.167^{\circ}[/tex]

La inclinación de la Torre de Pisa con respecto al eje vertical es 25.167º.

Answer:

true

Step-by-step explanation:

We can see why this is true by decomposing and rearranging the parallelograms into rectangles. Notice that the side lengths of each rectangle are the base and height of the parallelogram. Even though the two rectangles have different side lengths, the products of the side lengths are equal, so they have the same area!

Answer:

a) Speed of the cyclist is (2.75/0.4) = 6.875 miles per hour.

b) It will take (5.5/6.875) = 0.8 hours to travel 5.5 miles at this rate.

Answer:

x = 53/9

Step-by-step explanation:

9 x - 2×(8) = 37

9 x - 16 = 37

9 x = 37 + 16

9 x = 53

x = 53/9

Given:

In a right angle triangle, two interior angles are 60° and 30°, and their opposite sides are x and 3 respectively.

To find:

The length of side x in simplest radical form with a rational denominator.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

Using this formula for the given triangle, we get

[tex]\tan 30^\circ=\dfrac{3}{x}[/tex]

[tex]\dfrac{1}{\sqrt{3}}=\dfrac{3}{x}[/tex]

On cross multiplication, we get

[tex]1\times x=3\times \sqrt{3}[/tex]

[tex]x=3\sqrt{3}[/tex]

Therefore, the length of side x in simplest radical form is [tex]3\sqrt{3}[/tex] units.

Replace the letter with their values and solve:

-1 + 3(7) - 4(-1) + 10(7)

Simplify:

-1 + 21 + 4 + 70 = 94

The answer is 94

Answer:

29

Step-by-step explanation:

AB+BC=AC

12+17=29=AC

Answer: Alex is 15 years

Step-by-step explanation:

Since Alex is w years old and her sister is three years younger than him. The age of his sister will be:

= w - 3.

We will then multiply their ages and equate to 180. This will be:

w × (w - 3) = 180

w² - 3w = 180

w² - 3w - 180 = 0

w² - 15w + 12w - 180 = 0

w(w - 15) + 12(w - 15) = 0

(w + 12)(w - 15)

w - 15 = 0

w = 0 + 15

w = 15 years

Alex is 15 years, her sister is 12 years.

Answer:

576

Step-by-step explanation:

3 x 8= 24

24^2= 576ft

Answer:

192 ft²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here r = 8 , then

A = π × 8² = 3 × 64 = 192 ft²

Answer:

Step-by-step explanation:

240 | Total

6x10=60 square feet | Bathroom

240-60=180

Square foot of 180 is 16.7225

Length of Anthony's bathroom is 16.7225

Answer:

The ratio of smaller rectangle to larger is 1 : 8.

Step-by-step explanation:

Given that:

Area of smaller rectangle = 25 square feet

Area of larger rectangle = 200 square feet

Ratio of areas of these similar rectangles;

Smaller rectangle : Larger rectangle

25 : 200

1 : 8

Hence,

The ratio of smaller rectangle to larger is 1 : 8.

Answer:

x ≤ 25mph

Step-by-step explanation:

Given that :

Speed limit drops to 15 miles per hour at curve

Driver slows down by 10 miles per hour as he drives around the curve

The driver's speed before reaching the curve is :

Let speed befure curve = x

Lowest speed before curve = 15 +. 10 = 25 mph

x ≤ 25mph

Answer:

There is no possible answers

Step-by-step explanation:

We are told in the above question that:

"The HCF of my two numbers is 6.

This means the two numbers are factors of 6

"The LCM of my two numbers is 15"

LCM means the lowest common multiple.

This means the two numbers must be have 15 as one of its multiples.

From the above explanation above, there are no two numbers like that

Answer:

Simple interest is: $2976

Account balance is: $9176

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 12%/100 = 0.12 per year,

then, solving our equation

I = 6200 × 0.12 × 4 = 2976

I = $ 2,976.00

The simple interest accumulated

on a principal of $ 6,200.00

at a rate of 12% per year

for 4 years is $ 2,976.00.

Step-by-step explanation:

Answer:

1800litres

Step-by-step explanation:

Let the total litres in the tank be x

If the tank is two - thirds full of water, then the total litres initially will be 2x/3 litres

When 300 litres is used, then the remaining will be 2x/3 - 300

Equating this to half of the tank i.e x/2, we will have:

2x/3 - 300 = x/2

Collect like terms

2x/3 - x/2 = 300

Multiply through by 6

4x - 3x = 300(6)

4x-3x = 1800

x = 1800

This means that the tank can hold 1800litres of water

Answer:

11.43 ft

Step-by-step explanation:

Mean = sum of low tides / total number of low tides

(20.22 ft + 2.64 ft + 20.22 ft + 2.64 ft.) / 4 = 11.43ft

Answer:  =-1/2x+-1/2y

Step-by-step explanation:

Answer:

5z = 40 and 5z = -40

Step-by-step explanation:

Since the equation is absolute value it will produce two equations 5z=40 and 5z=-40 since the 5z could be positive or negative, we can't tell with the absolute value bars

Answer:

No.

Step-by-step explanation:

Since we know the side lengths of the triangle, we can figure out whether or not this is a Pythagorean triple.

Pythagorean theorem: a^2 + b^2 = c^2

a and b are both smaller than c.

So,

8^2 = 64.

13^2 = 169.

15^2 = 225.

64 + 169 = 233.

233 is not equal to 225.

Therefore, this is not a right triangle.
