Tinky Winky is 2 years younger than Laa Laa. If the product of Tinky's and Laa Laa's ages is equal to 1 less than 5 times the su

dybincka [34]

Answer:

<h3><u>Solution</u><u>:</u><u>-</u></h3>

Let

Tinky's age=x

Laa's age=x+2

According to the question

$\qquad\quad {:}\longmapsto\sf 5 (x+x+2)-1=x (x+2)$

$\qquad\quad {:}\longmapsto\sf 5(2x+2)-1=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x+5-1=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x+4=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x-2x+4=x^2$

$\qquad\quad {:}\longmapsto\sf x^2=8x+4$

$\qquad\quad {:}\longmapsto\sf x^2-8x-4=0$

170 is 1/10 of 17 true or false 170 is 1/10 of 17 true or false

Zarrin [17]

Let's see if that's really true! :)

170=x(17)
170=17x
17x=170
17x / 17=170 / 17
x=10

So the answer to your question is false.

170 is actually 10/1 OR 10 of 17.

Find the product. Write your answer in<br> exponential form.<br> 6^-4•6^-9

Karolina [17]

Answer:

6^-13

Step-by-step explanation:

The rule for multiplying numbers with the same base but different exponents is a^b*a^c=a^(b+c), so in this case we have 6^(-4+(-9)) which is 6^-13

Hope this helped!

How do you use special right triangles to solve for missing sides? (30-60-90 and 45-45-90 triangles)

Assoli18 [71]

Answer: see below

Step-by-step explanation:

30 - 60 - 90 triangles have angles in the triangle measuring 30, 60, and 90 degrees. A 30 - 60 - 90 triangle also has special side ratios according to a side's location in the triangle.

The side across from the 30 degree angle is represented by x.

The side across from the 60 degree angle is represented by x $\sqrt{3}$ .

The side across from the 90 degree angle is represented by 2x.

45 - 45 - 90 triangles have angles in the triangle measuring 45, 45, and 90 degrees. A 45 - 45 - 90 triangle has special side ratios similar to the 30 - 60 - 90 triangle.

The side across from either of the 45 degree angles is represented by x.

The side across from the 90 degree angle is represented by x $\sqrt{2}$ .

These ratios can be used to find missing sides. If you know that a triangle is one of these special triangles and you also know one of its side lengths, you can plug the known length in for x in the proper place.

EX: you have a 30 - 60 - 90 triangle with a side length of 2 across from the 30 degree angle. You then know that the side across from 60 is 2 $\sqrt{3}$ and the side across from 90 is 4.
