Find the length of the missing side. The triangle is not drawn to scale.

Answer:

D.) 8

Step-by-step explanation:

You can use the Pythagorean theorem because this is a right triangle:

a^2+b^2=c^2

a and b are the legs and c is the hypotenuse. The hypotenuse is always the longest side in a right triangle (since it  is opposite the biggest angle). The two legs squared have to add up to the hypotenuse squared.

Fill in values:

a^2+15^2=17^2

Simplify exponents:

a^2+225=289

Isolate the variable. Subtract 225 from both sides:

a^2+225-225=289-225\\a^2=64

Find the square root of both sides:

\sqrt{a^2}=\sqrt{64}\\  a=8

The missing leg length is 8.

Give an example of two numbers that are both 6-digit numbers, but the greater number is determined by the hundreds place
SashulF [63]
The order of the numbers for a 6-digit number from left to right is as follows:
hundred thousands, ten thousands, thousands, hundreds, tens and then units

We want two numbers were the greater number is determined by its hundreds place, these two numbers can be:
165,827 and 165,229
The hundreds in the first is 8 while the hundreds in the second is 2. Therefore, the first number is larger.

Factor the following polynomial completely.<br> 2x2 – 10x – 28
erastovalidia [21]

Answer:

2(x - 7)(x + 2)

Step-by-step explanation:

Given

2x² - 10x - 28 ← factor out 2 from each term

= 2(x² - 5x - 14) ← factor the quadratic

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)

The factors are - 7 and + 2 , since

- 7 × 2 = - 14 and - 7 + 2 = - 5 , thus

x² - 5x - 14 = (x - 7)(x + 2) and

2x² - 10x - 28 = 2(x - 7)(x + 2)

 Suppose you have a bag with 20 letter tiles in it and 7 of the tiles are the letter Upper Y. If you pick a letter tile at rando
KonstantinChe [14]

Answer:

Step-by-step explanation:

Probability is expressed as

Number of favorable outcomes/number of total outcomes

Considering the first bag, the probability that you pick a letter that is Upper Y is 7/20 = 0.35

Converting to percentage, it becomes

0.35 × 100 = 35%

Considering the second bag, the probability that you pick a letter that is Upper Y is 240/500 = 0.48

Converting to percentage, it becomes

0.48 × 100 = 48%

Therefore, you are more likely to pick a tile that is the Upper Y letter from the second bag.
