So it says 8 less than, meaning 8 minus the product of 5 and -4, so literally it means subtract 8 from 5X-4
8-5*-4

8 less means subtracting 8 from ___.
The product of 5 and -4 is (5×-4)
So you want to subtract 8 from (5×-4)
(5×-4)-8, -20-8=-28

Find each measurement indicated. Round your answers to the nearest tenth.

Answer:

Step-by-step explanation:

Find AB using the Law of Sine:

$\frac{AB}{sin(C)} = \frac{AC}{sin(B)}$

Thus:

$\frac{AB}{sin(40)} = \frac{47}{sin(103)}$

Multiply both sides by sin(40)

$\frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40)$

$AB = \frac{47*Sin(40)}{sin(103)}$

AB = 31.0056916 ≈ 31.0 cm (nearest tenth)

Answer:

A. 10

Step-by-step explanation:

First put the numbers in order from least to greatest then find the two numbers in the center of that since there is an even number of numbers there will be two the add and divide by two and you get 10.

A cube has a surface area of 486 cm2. What is the side length ?

astraxan [27]

A Cube, has all equal sides, namely, the length, width and height
are all equal to each other

so.. notice the picture added here
you have really, 6 squares, stacked up to each other at the edges

so...what is the Area of one of those squares?
well, if the sides are equal, let's say the side is "x" long, then
the Area is $x\cdot x \implies x^2$

well, you have 6 of those squares, thus $\bf \textit{surface area of a cube}=
\begin{cases}
(x\cdot x)+\\
(x\cdot x)+\\
(x\cdot x)+\\
(x\cdot x)+\\
(x\cdot x)+\\
(x\cdot x)\\
 --------------\\
 x^2+x^2+x^2+x^2+x^2\\
6x^2
\end{cases}
\\\\
\textit{we know the Area is }486\ cm^2\qquad thus
\\\\
\textit{surface area}=6x^2\implies 486=6x^2$

solve for "x", to get one side's length

One part of the electromagnetic spectrum that arrives on Earth as solar radiation from the Sun is the visible spectrum. Waveleng

Vlad1618 [11]

White light is the answer.

Also known as visible light consist of a spectrum of different waves. Technically, white is not a color or a wavelength characterized by a white color. Rather, White light is a combination of many colors of the visible spectrum. It shows the full spectrum of electromagnetic spectrum.
