John is 12 years and 4 months old !!

Step-by-step explanation:

Answer:

A) 843.75 ft³

B) 15.625ft³

C) 54 boxes

Step-by-step explanation:

A) To find the volume of a rectangular prism (the cargo hold is a rectangular prism), you multiply the length, the width and the depth:

Volume = length x width x depth

Volume = 15 x 7.5 x 7.5

Volume = 843.75 ft³ (ft³ or cubic feet is the unit for volume in feet)

B) The volume of a cube (the boxes are cube-shaped) is also found by multiplying the length, the width and the depth:

Volume = length x width x depth

Volume = 2.5 x 2.5 x 2.5

Volume = 15.625ft³

C) To find the amount of boxes that can fit, we see how many times the volume of one box goes into the volume of the cargo hold. Divide the volume of the cargo hold by the volume of the box:

843.75 ÷ 15.625 = 54

Answer:

(- 1, - 2 )

Step-by-step explanation:

Given the 2 equations

y = - 2x - 4 → (1)

y = 4x + 2 → (2)

Substitute y = 4x + 2 into (1)

4x + 2 = - 2x - 4 ( add 2x to both sides )

6x + 2 = - 4 ( subtract 2 from both sides )

6x = - 6 ( divide both sides by 6 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

y = 4(- 1) + 2 = - 4 + 2 = - 2

solution is (- 1, - 2 )

Answer:

4. a) y=1x+2

   b) y=0x

   c) y=0x

   d) y=1x+0

Step-by-step explanation:

The formula for slope intercept form is y=mx+b and the formula for slope is rise/run.

b= y intercept and m=slope.

4.b and 4.c do not cross the y intercept.

Answer:

7.0

Step-by-step explanation:

Right angled triangle. To find the hypotenuse, use Pythagorean theorem.

Hypotenuse² =  base² + altitude²

                      = 6.5² + 2.7²

                      = 42.25 + 7.29

                     = 49.54

hypotenuse = √49.54 = 7.04 = 7

Step-by-step explanation:

by using Pythagoras law

h²=p²+b²

missing angle =h let

h²=(2.7)²+(6.5)²

h=√(49.50)=7.03=7

Answer:

5.6 cm

Step-by-step explanation:

use the cosine ratio to get the answer since AB is the adjacent side and the hypotenuse has already been given

Step-by-step explanation:

Answer:

0.00661 pound

Step-by-step explanation:

If 3 kilograms = 6.618 pounds than There are approximately 0.006636 pounds in 3 grams. To convert grams to pounds, we can use the given conversion factor: 3 kilograms = 6.618 pounds.

First, we need to convert 3 grams to kilograms. Since there are 1000 grams in a kilogram, we divide 3 grams by 1000 to obtain the equivalent value in kilograms:

3 grams / 1000 = 0.003 kilograms

Now, we can use the conversion factor to convert kilograms to pounds. Multiplying the equivalent kilograms (0.003) by the conversion factor:

0.003 kilograms * (6.618 pounds / 3 kilograms) = 0.006636 pounds

Therefore, there are approximately 0.006636 pounds in 3 grams.

19.

6,\ 12,\ 12\sqrt{2}

Step-by-step explanation:

The required values of the x, y, and z in the given triangle are 26√3, 13√3, and 39×√2 respectively.

If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.

Here,
For triangles,
sin45 = 39/x
z = 39×√2

xsin60 = 39×√2 cos45
x ×√3/2 = 39
x = 39 × 2 / √3
x = 26√3

Now,
cos60= y / x
1/2 = y / 26√3
y = 13√3

Thus, the required value of the x, y, and z in the given triangle are 26√3, 13√3, and 39×√2 respectively.

Answer:

16 m

Step-by-step explanation:

Use Pythagorean theorem,

hypotenuse² = base² +altitude²

                      = 5² +6²

                      = 25 + 36

                      = 61

First diagonal = [tex]\sqrt{61}[/tex] = 7.81 m

Second diagonal² = first diagonal² + altitude²

                              = [tex](\sqrt{61})^{2}[/tex]  + 3²

                              = 61 + 9

                              = 70

second diagonal = [tex]\sqrt{70}[/tex] = 8.37 m

First diagonal  + second diagonal = 7.80 + 8.37 = 16.17 = 16

Answer:

x = 117 degrees

Step-by-step explanation:

Find the diagram attached

From the diagram, the angle at the top left on line t is equal to theta of the top left on line u and is equal to 117 degrees (corresponding angle)

Also the angle angle on the top left on line u will be equal to x (vertically opposite angle)

Hence the value of x = 117 degrees (vertically opposite to each other on line u)

Answer:

El precio de cada kilogramo de naranja y de manzana es 0.9 soles y 2 soles respectivamente.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

En este caso, se debe plantear un sistema de ecuaciones. Se determinan las variables:

Juan el primer día gastó 8,90 soles en total al comprar 1 kg de naranjas y 4 kg de manzanas; y el segundo día gastó 24,50 soles al comprar 5 kg de naranjas y 10 kg de manzanas. Entonces el sistema de ecuaciones a resolver es:

[tex]\left \{ {{x+4*y=8.90} \atop {5*x+10*y=24.50}} \right.[/tex]

Se decide resolver el sistema a través del método de sustitución, que consiste en despejar una de las incógnitas en una de las ecuaciones y sustituir su valor en la siguiente. En este caso despejando la variable x de la primera ecuación se obtiene:

x= 8.90 - 4*y

Reemplazando esta expresión en la segunda ecuación se obtiene:

5*(8.90 -4*y) + 10*y=24.50

Resolviendo se obtiene:

5*8.90 -5*4*y + 10*y=24.50

44.5 -20*y + 10*y=24.50

-20*y + 10*y=24.50 -44.5

-10*y= -20

y= (-20)÷ (-10)

y= 2

Reemplazando el valor de y obtenido en la expresión x= 8.90 - 4*y se obtiene:

x= 8.90 - 4*2

x= 8.90 - 8

x=0.9

El precio de cada kilogramo de naranja y de manzana es 0.9 soles y 2 soles respectivamente.
