Mila [183]2 years ago
4 0

Answer:

-0.39mL

Step-by-step explanation:

Let x be the number.

The expression would be: 0.40 + x = 0.01

Apply algebra to the equation to solve for x. You can subtract 0.40 from each side to simplify the expression. Here's what it should look like after applying algebra: x = -0.39

Therefore the answer is -0.39mL

Isaiah writes an expression with 5 terms. All 5 terms are like terms. How
Goshia [24]

Answer:

1

Step-by-step explanation:

Since all 5 terms are like terms they can all be combined into 1 term. For example, 3x + 8x + 5x + 4x + 19x = ?. Since they all have the term x they can be combined into 39x. That leaves 1 term.

Which equation can be used to calculate the area of the shaded triangle in the figure below?
lozanna [386]

Answer:

A

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here b = 14 and h = 4, hence

A = \frac{1}{2} (14 × 4) = 28

e-lub [12.9K]

Answer:

x=36.772  

Step-by-step explanation:

Given : Expression x=25.36+0.45(25.36)

To find : Solve the expression ?

Solution :

Step 1 - Write the expression,

x=1(25.36)+0.45(25.36)

Step 2 - Apply distributive, ab+ac=a(b+c)

Here, a=25.36, b=1, c=0.45

x=25.36(1+0.45)

Step 3 - Solve the expression,

x=25.36\times 1.45

x=36.772

Therefore, x=36.772

Si consideras como base uno de los rectángulos de dimensiones de 5cm y 3cm ¿cuanto mide la altura de ese prisma?
Vinvika [58]

Respuesta:

h = V / 15

Explicación paso a paso:

El volumen de un prisma rectangular se calcula usando la relación:

Largo ancho alto

Donde, largo y ancho son la dimensión de la base

Por eso,

Volumen = Base * altura

Volumen = (5 cm * 3 cm) * altura

De la pregunta, no se da el volumen, por lo tanto, tomamos el volumen como V en otro para calcular la altura, h

V = 15h

Divide ambos lados entre 15

V / 15 = 15h / 15

V / 15 = h
