Which of the following demonstrates the Associative Property?
A. 2(3 - a) = 2.3+2.a
B. 4(a + b) = 4ab
C. -2(a-3) = -2a +6
D. (a + c)+ a = a +(c + a)

Answers

Answer 1

Answer:

the answer is D!

Step-by-step explanation:

the associative property states "rearranging the parenthesis in an expression will not change the result."

(a+c)+a=a+(c+a)

they're still going to equal the same! :)

A trip, including hotel and air, is prices at $319.19 after tax. If the tax rate is 12%, calculate the price before tax that will result in this tax-included amount

Answers

Answer: $285

Step-by-step explanation:

Given

A trip costs [tex]\$319.19[/tex] after-tax inclusion

The rate of tax is 12%

Suppose x is the amount of charge before tax inclusion

We can write

[tex]\Rightarrow x+12\%x=319.19\\\Rightarrow x(1+0.12)=319.19\\\\\Rightarrow x=\dfrac{319.19}{1.12}\\\\\Rightarrow x=\$284.99\approx \$285[/tex]

The amount before tax inclusion is $285

Determine whether the triangle with the given side lengths is acute,
right, obtuse or not a triangle 14,16,27

Answers

Answer:

this triangle is "obtuse

Step-by-step explanation:

Since sides 14 and 16 add up to 30, which is more than the third side, 27, we DO have a triangle here.  The sides of lengths 14 and 16 form an angle greater than 90 degrees, and so this triangle is "obtuse."  It's not a right triangle either, because the Pythagorean Theorem is not satisfied:  14^2 + 16^2 = 452, which is NOT 27^2.

Jenna's dogs used 999 chew toys last year. The animal shelter used 2,277 277 chew toys. How many times as many chew toys did the animal shelter use? How to do

Answers

Answer: 2.28 times

Step-by-step explanation:

When finding out the number of times more that the animal shelter used chew toys than Jenna's dogs, you need to divide the number used by the animal shelter by Jenna:

= Number used by animal shelter / Number used by Jenna's dogs

= 2,277 / 999

= 2.28 times

Notice that if you multiply Jenna's dogs 999 toys by 2.28 you will get approximately 2,277.

We have to find the equivalent expression

Here we use the exponent rule:

Which exponent rule we use here?

[tex]a^b\cdot a^c=a^{b+c}\\[/tex]

here base is the same of both the number

If base are same then we can add the exponent

Therefore,In a given expression base is 5 therefore the

[tex]5^{12}\cdot5^{85}=5^{12+25}\\5^{12}\cdot5^{85}=5^{97}[/tex]

Therefore the given expression [tex]5^{12}\cdot5^{85}[/tex]equivalent to the [tex]5^{97}[/tex].
