Answer:

Ex: Shown in #12. 12 x 12 x 12 x 12= 12 with the power of 4

13. 5 x 5 x 5 x 5 x 5 x 5 x 5 =5 with the power of 7 (simple)

14. 7 x 10 x 10 x 10=7/10 with the power of 3 or 4 (i think)

15. 16 x 10 x 10 x 10 x 10= 16/10 with the power of 4 or 5 (sorry if im wrong)

16. 25,000,000= 2.5 x 10^y (im pretty sure)

Again sorry if im wrong and have a wonderful day!!!

This is an isosceles triangle. The angles at the base are congruent (they have the same measures).

Look at the picture.

We know: The sum of the measures of angles in a triangle is equal 180°.

Therefore we have the equation:

$2x-10+2x-10+3x+25=180$ <em>combine like terms</em>

$(2x+2x+3x)+(-10-10+25)=180$

$7x+5=180$ <em>subtract 5 from both sides</em>

$7x=175$ <em>divide both sides by 7</em>

$x=25$

$m\angle A=2x-10\to m\angle A=2(25)-10=50-10=40\\\\m\angle C=m\angle A=40\\\\m\angle B=3x+25\to m\angle B=3(25)+25=75+25=100^o$

<h3>Answer: D. m∠C = 40</h3>

Given the sequence 10, 20, 40, 80,.... find 25th term

Contact [7]

This sequence is a geometric sequence so u want to find out the formula

The formula for a geometric sequence is: ar to the power of n-1

A= first term and r= the factor between the terms (called the common ratio)

Now we juss input it in the formula

10 x 2 to the power of n-1

Now we want to work out the 25th term so n=25 we do 25-1=24

So it’s 10*2 to the power of 24

LMN is a right triangle. True or False

dusya [7]

Answer:

False

Step-by-step explanation:

Let us check using Pythagorean Theorem

$c^2 = a^2 + b^2$

Where c is the hypotenuse (14), a is the base (13) and b is the perpendicular (5)

Putting in the above formula

$14^2 = 13^2 + 5^2$

196 = 169+25

196 ≠ 194

So, It is not a right angled triangle

Round 6.7086 to the nearest thousandth

Bingel [31]

$\text {Hello! Let's solve this Problem!}$

$\text {To round to the nearest thousandth you must underline the thousandth place}$ $\text {(which is 8), point an arrow to 6 (in the ten-thousandth place)}$

$\text {If the number is 5 or more you raise the score. Meaning you add 1 to the}$ $\text {thousandth place. If the number is 4 or lower you keep the number the same.}$
