1) Nearest thousand: 457,000 (Look at the thousandths place. Is the number closer to 457,000 or 456,000?)
Hundred: 457,000 (Look at the hundredths place. Is the number closer to 456,000 or 457,000?)
Ten: 456,990 (Look at the tenths place. Is the number closer to 456,980 or 456,990?)

2) The value of the expression when x=6 is 27. Explanation:
6x-7
6(6)-7
36-7
27
The value of the expression when x=3 is 11
Explanation:
6x-7

Consider the triangle. Which shows the order of the angles from smallest to largest? angle A, angle B, angle C angle B, angle A,

Katyanochek1 [597]

Answer:

angle B, angle A, angle C

Step-by-step explanation:

The shortest side length will be opposite the smallest angle, and the longest side length will be opposite the largest angle.

When the triangle is drawn and labeled, we see that AB is opposite angle C; BC is opposite angle A; and CA is opposite angle B.

Since the smallest side is AC, this means the smallest angle is angle B.

Since the middle length side is BC, the middle sized angle is A.

Since the longest side is AB, the largest angle is C.

This means the order from smallest to largest is B, A, C.

If the streets of a city are straight lines and the intersections are points, show how Principle 2 and Principle 3 might be illu

Naily [24]

Step-by-step explanation:

In the plane geometry Abeka, second edition, it is given :

Principle 2 states that between any two points, only one straight line can be drawn.

And according to principle 3 two straight lines interacts at one point only.

Thus this can be well illustrated by two straight lines which are represented by the streets of a city and these two streets intersects at a point.

The answer to this question is 23. How you get this is by adding all the sides like this: 2n+6+135+151+140+63=540. Then you just solve the equation.

How to solve this??<br><br> (r^-7b^-8) ^0<br> -------------<br> (t^-4w)

professor190 [17]

keeping in mind that anything raised at the 0 power, is 1, with the sole exception of 0 itself.

$\bf ~~~~~~~~~~~~\textit{negative exponents}
\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad a^n\implies \cfrac{1}{a^{-n}}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\cfrac{(r^{-7}b^{-8})^0}{t^{-4}w}\implies \cfrac{1}{t^{-4}w}\implies \cfrac{1}{t^{-4}}\cdot \cfrac{1}{w}\implies t^4\cdot \cfrac{1}{w}\implies \cfrac{t^4}{w}$
