Answer:

By "small numbers" you probably mean exponents. The exponent just represents how many times you multiply the number by itself. For example, 4^{3} means 4 x 4 x 4, which equals 64.

The "letters" are called variables. They represent an unknown value. The most common variables you'll see are x and y, which are used a lot in graphing. Variables are often used in equations. For example:

<em />

<em>"Maria wants to buy cupcakes, at $2.50 each. She only has 10 dollars. How many cupcakes can she buy?" </em>

You would use an exponent to solve this problem. If you make cupcakes "C" then you can say:

C (the # of cupcakes) times 2.50 (cost per cupcake) = 10.

(in shorter terms, 2.50c=10.)

You can then solve for "c" by dividing by 2.50 on both sides and you can then see that Maria has enough money to buy 4 cupcakes.

Hope this helps! :)

The small numbers in math shows that you have to mutiplies how much the power is. For Example, 5 with a power of 2 → 5² that's what it looks like.

Sara takes 1/6 of an hour to vacuum his moms car it takes 4 times that long to wash the car then it takes you to wax the car twi
Nataly [62]
<h2>Answer:</h2><h2>2 hours & 10 minutes </h2><h2>Step-by-step explanation:</h2><h2>1/6 of an hour is 10 minutes. She vacuumed for 10 minutes. It took 4 times as long to wash the car so 10 * 4 = 40. She washed the car for 40 minutes. It took her twice as long to wax the car as it did for her to wash it so 40 * 2 = 80. She waxed the car for 80 minutes. 10 + 40 + 80 = 130 minutes or 2 hours and 10 minutes. </h2>

what are the factors of 47 (cuz im STUPID and i dont feel like doing this cuz im working on geogrophy)
Hitman42 [59]

Hey there! I'm happy to help!

The factors are the numbers you multiply to get 47. And they can't be fractions or numbers with fractions. They have to be integers (numbers without fractions).

So far, we see that we can multiply 1 and 47 to get 47. To see if there are any more, we see what numbers 1-10 we can divide by.

We cannot divide by 2 because 47 is odd.

We cannot divide by 3 because it gives us 15.6666...

We can't divide by 4 because 47 is odd.

We can't divide by 5 because 47 does not have a 5 or 0 in the ones place.

We can't divide by 6 because 47 is odd.

We can't divide by 7 because it gives us 6.714285....

We can't divide by 8 because 47 is odd.

We can't divide by 9 because it gives us 5.2222

And we obviously can't divide it by 10.

Therefore, the factors of 47 are 1 and 47. A number whose only factors are 1 and itself is called a prime number.

I hope that this helps! Have a wonderful day! :D

Does Anyone know this?

Answer:

∠AEC = 139°

Step-by-step explanation:

Since EC bisects ∠BED then ∠BEC = ∠CED = 4x + 1

∠AED = ∠AEB + ∠BEC + ∠CED = 180 ← straight angle

Substitute values into the equation

11x - 12 + 4x + 1 + 4x + 1 = 180, that is

19x - 10 = 180 ( add 10 to both sides )

19x = 190 ( divide both sides by 19 )

x = 10

Hence

∠AEC = ∠AEB + ∠BEC = 11x - 12 + 4x + 1 = 15x - 11, hence

∠AEC = (15 × 10) - 11 = 150 - 11 = 139°
