In an isosceles triangle, the third angle is ten times the measure of each of the congruent angles. What is the measure, in degrees, of the largest angle? Explain how you got this answer.

Answers

Answer 1

Answer: The angles of the triangle would be represented by x for the congruent sides and 10x for the 3rd angle.
All of the angles in a triangle equal 180°
The equation would be set up like this:
12x=180
x=15°
10x= 150°

A matchbox has a mass of 20 g. The mass of the match box alone is 8 g. If there are 6 matches in the box,what is the mass of each box?

Answers

Hence mass of 6 matches is 6 gm

What is mass?

Anything that occupies space is said to have acquired mass. That means quantitative measure of inertia, a fundamental property of all matter.

How to solve?

Given mass of 1 match box=20g

Mass of match box alone = 8 g

Mass of match box if it has 6 matches= 20-8(weight of matches)

If box has 20 matches in all 1 match will have mass of 1 gm then 6 matches will have mass of 6 matches.

Each match has a mass of 2 g. This is because you must take the matchbox's total mass and subtract the mass of the box alone. You get 12, and then you divide by 6 to find the amount of each match

Step-by-step explanation:

The applicable property of exponents is ...

$\sqrt[n]{x^m}=x^{(m)/(n)}$

The 4th selection uses this property directly. The 3rd selection uses the property

$(a^b)^c=a^(bc)$

to show that the cubes of the two expressions are equivalent. Since all the numbers involved are real numbers, this is equivalent to showing the expressions equivalent.

Whats a word phrase for 25-0.6x

Answers

Answer:

(1) 25 is decreasing by 0.6x

(2) 0.6x less from 25

Step-by-step explanation:

We have been given an expression 25-0.6x

We have to write it in word phrase

We can see that 25 is decreasing by some number

we can write it as:

(1) 25 is decreasing by 0.6x

(2) 0.6x less from 25

Since, we can rewrite -0.6x+25 which will lead to the statement

-0.6x exceeds by 25.

how do you do percent proportions? I'm learning those right now, and I have no idea what to do. my teacher isn't the best at explaining things. an example of what I don't get is "4% of what number is 10?" also things such as "16 is what percent of 64?"

Answers

Remember these tips:

=> To turn apercent into a decimal, move the decimal point 2 places to the left.
4%means 0.04 , and 50% means 0.5 .

=> To turn a decimal into percent, movethe point 2 places to the right.
0.062 means 6.2% .

=> Inmath, whenever you see the word "of", it almost always means "times".
So your 2nd example means

16 = (mystery number) x (64).

Divide eachside by 64 : 16/64 = mystery number = 1/4 = 0.25 .

Move the point 2places to the right. 0.25 = 25% .
