x = 9/4

Step-by-step explanation:

2x - x + 9 + 3x - 2 = 16

Combine like terms

4x + 7 = 16

Subtract 7 from both sides

4x = 9

Divide both sides by 4

x = 9/4

Answer:

186 pounds

Step-by-step explanation:

volume : base area × height

area of rectangular triangle : a×b/2

Vp = (5.5 × 12 / 2) × 7.5 = 33 × 7.5 = 247.5 ft³

the weight of the contents : 247.5 × 0.75 = 185.625 pounds

= 186 pounds (rounded)

Given:

[tex]a=-\dfrac{3}{4}[/tex]

[tex]b=\dfrac{4}{5}[/tex]

To verify:

[tex]a\div b\neq b\div a[/tex]

Solution:

We have,

[tex]a=-\dfrac{3}{4}[/tex]

[tex]b=\dfrac{4}{5}[/tex]

Now,

[tex]a\div b=\dfrac{a}{b}[/tex]

[tex]a\div b=\dfrac{-\dfrac{3}{4}}{\dfrac{4}{5}}[/tex]

[tex]a\div b=-\dfrac{3}{4}\times \dfrac{5}{4}[/tex]

[tex]a\div b=-\dfrac{15}{16}[/tex]               ...(i)

And,

[tex]b\div a=\dfrac{b}{a}[/tex]

[tex]b\div a=\dfrac{\dfrac{4}{5}}{-\dfrac{3}{4}}[/tex]

[tex]b\div a=\dfrac{4}{5}\times (-\dfrac{4}{3})[/tex]

[tex]b\div a=-\dfrac{16}{15}[/tex]               ...(ii)

From (i) and (ii), it is clear that

[tex]a\div b\neq b\div a[/tex]

Hence verified.

Answer:

aₙ = 1 + 1(n - 1)

Step-by-step explanation:

This is an arithmetic sequence, which will use the equation:

aₙ = a₁ + r(n - 1)

Therefore the expression for the nth term would be:

aₙ = 1 + 1(n - 1)

PK = 75

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{PK}{WK}[/tex] = [tex]\frac{AK}{NK}[/tex] , substitute values

[tex]\frac{PK}{54}[/tex] = [tex]\frac{62.5}{45}[/tex] ( cross- multiply )

Answer:

-4 19/20

Step-by-step explanation:

2 1/5 ÷ -4/9

Change to an improper fraction

(5*2+1)/5 =11/5

Copy dot flip

11/5 * -9/4

-99/20

Changing back to mixed number

-4 19/20

Answer:

-99/20 or -4.95

Step-by-step explanation:

make the first fraction a simple fraction by multiplying the denominator by the whole number and adding the numerator.

which equals 11/5. Then you multiple by the reciprocal of 4/-9 which is -9/4

to look like 11/5 * -9/4 = -99/20

Answer:

La madre hizo en total 2 y 3/8 litros de jugo.

Step-by-step explanation:

Sabemos que preparó:

3/4 litros de jugo de frutilla = 3/4 L

1 y 1/2 litro de jugo de manzana = (1 + 1/2) L  

1/8 litro de jugo de limón = 1/8 L  

1 y 1/2 litro de agua = (1 + 1/2) L  

¿Cuántos litros de jugo preparó la mamá?

Simplemente debemos sumar los distintos volúmenes de jugo escritos arriba (el de agua no, pues solo nos pregunta cuantos litros de jugo se prepararon)

Total de jugo = 3/4 L +  (1 + 1/2) L  + 1/8 L  

Para completar esta suma, separamos los números enteros de los racionales:

Total de jugo = 1 L + ( 3/4 + 1/2 + 1/8) L

Para resolver la suma dentro del paréntesis, debemos tener todos los números con el mismo denominador.

Recordar que si multiplicamos el numerador y el denominador por el mismo número, entonces el número racional no cambia.

Como el denominador más grande dentro del paréntesis es 8 (que tambien es multiplo de los otros dos), tratemos de reescribir los otros dos números de tal forma que su denominador también sea 8:

Total de jugo = 1 L + ( (2/2)*(3/4) +(4/4)*(1/2) + 1/8) L

                       = 1 L + (6/8 + 4/8 + 1/8) L

                       = 1 L + (11/8) L

podemos reescribir el segundo termino como:  

                        = 1L + (8 + 3)/8 L

                        = 1L + (8/8) L + (3/8) L

                         = 1L + 1L + 3/8 L

                          = 2L + 3/8 L

La madre hizo en total 2 y 3/8 litros de jugo.

In a pair of similar triangles, the corresponding sides are proportional. ... When the sides are corresponding it means to go from one triangle to another you can multiply each side by the same number. In the diagram of similar triangles the corresponding sides are the same color.

Answer:

answer is a 20+4i

Step-by-step explanation:

Answer:

(a) Equations for both

[tex]y = 500 + 12x[/tex] --- lifeguard

[tex]y = 15x[/tex] --- camp counselor

(b) Total pay for 5 days

Lifeguard pays $800

Camp counselor pays $375

(c) Which pays more

Lifeguard job pays more

Step-by-step explanation:

Let

[tex]x \to hours[/tex]

[tex]y \to total\ pay[/tex]

Given

Lifeguard job

[tex]Signing\ bonus = \$500[/tex]

[tex]Rate = \$12/hr[/tex]

Camp counselor job

[tex]Signing\ bonus =\$0[/tex]

[tex]Rate = \$15/hr[/tex]

Solving (a): The equation for both

The total pay for each job is calculated as:

Total Pay = Signing Bonus + Rate * Hours

So, we have:

Lifeguard

[tex]y = 500 + 12*x[/tex]

[tex]y = 500 + 12x[/tex]

Camp counselor

[tex]y = 0 + 15 * x[/tex]

[tex]y = 15x[/tex]

Solving (b): Total pay for 5 days

First, we calculate the total hours worked in 5 days

[tex]x = 5hrs/day * 5days[/tex]

[tex]x = 25hrs[/tex]

So, the pay for each is:

[tex]y = 500 + 12x[/tex]

[tex]y =500 + 12*25[/tex]

[tex]y =800[/tex] --- Lifeguard

[tex]y = 15x[/tex]

[tex]y = 15 * 25[/tex]

[tex]y = 375[/tex] --- camp counselor

Solving (c): Which job pays more

By comparing the solution in (b)

[tex]800 > 375[/tex]

Hence, lifeguard job pays more

Answer: complementary

Step-by-step explanation:

Complementary angles are angles that add up to 90 degrees

The sum of the measure of angles 1 and 2 is the right angle which is 90 degrees. Then the correct option is C.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

Angles 1 and 2 form a right angle.

2 lines form a right angle.

Another line extends between the 2 lines to form 2 angles.

The top angle is labeled 1, and the bottom angle is labeled 2.

Then the sum of the measure of the angle 1 and 2 is the right angle which is 90 degrees. Then the angles are known as complementary angles.

Then the correct option is C.

Hi there!

[tex]\large\boxed{\text{33 in}^2}[/tex]

Find the total area by breaking the figure into two rectangles, one trapezoid, and one triangle.

Rectangles:

A = l × w

A = 2.75 × 4 = 11 in²

Solve for the other rectangle's length by subtracting from the total:

12 - 2 - 3 - 4 = 3

A = 3 × 3 = 9 in²

Total rectangle area: 11 + 9 = 20 in²

Trapezoid:

A = 1/2(b1 + b2)h

A = 1/2(4.25 + 2.75)3 = 21/2 = 10.5 in²

Triangle:

A = 1/2(bh)

A = 1/2(2.5 · 2) = 2.5 in²

Add up all of the areas:

20 + 10.5 + 2.5 = 33 in²
