solve for x show all work

Answers

Answer 1

Answer:

x=4

Step-by-step explanation:

we know the ratio of left to right is 2:1 because 6:3=2:1

the horizontal lines are parallel, so the other set of numbers follows the same proportions

[tex]x^{2} +2x+11=2(x+13.5)\\x^{2} +2x+11=2x+27\\x^{2} +2x-2x=27-11\\x^{2} =16\\x=\sqrt{16} \\x=4[/tex]

Select the best term from the box to complete the sentence. The number 0.5 is written as a?

4. hundredth

Answers

The answer is a decimal because 1/2 as a decimal is 0.5

1. decimal

Why? You wouldn't say 0.5 is written as a "decimal point" because the decimal point is legit the decimal point. It's definitely not a hundred and a hundredth would look like "0.05"

La montaña más alta del mundo es Everest cuya altura es de 8.848m y la altura de la segunda montaña más alta es de 2hm 3dam y 7m menos ¿Cuantos metros de altura tiene la segunda montaña más alta del mundo

Answers

Answer:

La segunda montaña más alta del mundo tiene 8611 metros.

Step-by-step explanation:

La montaña más alta del mundo es Everest cuya altura es de 8.848m.

La altura de la segunda montaña más alta es de 2hm 3dam y 7m menos. Para calcular la altura que tiene la segunda montaña más alta del mundo, debes realizar primero un cambio de unidades sabiendo que

1 hm= 100 m1 dam= 10 m

Entonces podes aplicar las siguientes reglas de tres simple:

Si 1 hm equivale a 100 m, 2 hm equivale a ¿Cuántos metros?

[tex]metros=\frac{2 hm*100 m}{1 hm}[/tex]

metros= 200

Si 1 dam equivale a 10 m, 3 dam equivale a ¿Cuántos metros?

[tex]metros=\frac{3 dam*10 m}{1 dam}[/tex]

metros= 30

Entonces, la altura de la segunda montaña más alta es de 200 m+30 m+ 7 m menos que el Everest. Esto es, 237 metros menos que la montaña más alta del mundo. Entonces:

8848 metros - 237 metros= 8611 metros

La segunda montaña más alta del mundo tiene 8611 metros.

Actually Welcome to the concept of Isosceles triangles.

They have two sides equal to each other, so we get as,

==> 3x + 3 = 2x + 8

==> 3x - 2x = 8-3

==> x = 5

hence the length of AC = 5 units.

Answer:

AC = 5

Step-by-step explanation:

here's your solution

=> This is a isosceles triangle

=> both sides are equal.

=> AB = CB

=> 3x + 3 = 2x + 8

=> 3x - 2x = 8 - 3

=> x = 5

so, AC = 5

hope it helps

Mrs perez drove at constant rate of speed she drove a total of 33.75 miles in 3/4 of hours what was the speed in miles per hour that mrs Perez traveled if this situation is represented by the equation d=rt

Answers

Answer:

Speed in miles per hour = 45 miles per hour

Step-by-step explanation:

Given:

Distance cover by Mrs Perez = 33.75 miles

Time taken by Mrs Perez = 3/4 hours = 0.75 hour

Find:

Speed in miles per hour

Computation:

Speed = Distance cover / Time taken

Speed in miles per hour = Distance cover by Mrs Perez / Time taken by Mrs Perez

Speed in miles per hour = 33.75 / 0.75

Speed in miles per hour = 45 miles per hour

The radius is 6 and the height is 15 what is the volume in terms of pi the shape is a cone

Answers

Answer:

565.49 or if rounded to the nearest tenth, 565.5

Explanation:

The formula for finding the volume of a cone is V=1/3Bh

B = pi times the radius squared
