They are congruent triangles,

Ratio of their corresponding sides is 5:25, =1:5 (look for hypotenuse)

so, 5x = 18-x (same manner for variable one)

18 = 6x

x=3

SO, OPTION C IS THE ANSWER.

Congruent triangles so therefor teh ratio are the same

5/x=25/(18-x)
multily both sies by (x(18-x))
5(18-x)=25x
90-5x=25x
add 5x to both sides
90=30x
divide both sides by 30
3=x
C is answer

When you divide with negative exponents, you divide the rational numbers like normal and then you add the exponents.

Doss [256]

Answer:

the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.

___H2 + ___Br2 → ___HBr

Vaselesa [24]

Answer:H2+Br2-->2HBr

Step-by-step explanation:

The amount of atoms on the left side must be equal to the amount of atoms on the right side for each element.

On the left you got 2xH and 2xBr.

This means you must have the same amount on the right.

2HBr =2xH + 2xBr

Correct answers only please! If you don't know the answer, then please don't guess or say what you think it is.

Answer:

The option "C" is correct

#in my opinion#

Step-by-step explanation:

The size of a screen is generally measured diagonally.

Thus to find the diagonal length,

we take help from Pythagoras theorem

$i.e. \\ {h}^{2} = {b}^{2} + {p}^{2}$

where h (hypotenuse) is the diagonal length, b (base) is the length of horizontal side, and p (perpendicular) is the length of the vertical side of the TV,

THUS the diagonal length or hypotenuse

$h = \sqrt{ {b}^{2} + {p}^{2} } \\ \: = \sqrt{1024 + 324} \\ \: = \sqrt{1348} \\ \: = 36.7 \: (= aprox \: 37)$

If you draw a card out of a deck of cards at random, what is the probability

LekaFEV [45]

Answer:

$\frac{1}{13}$

Step-by-step explanation:

Probability is the number of favorable outcomes divided by the number of total outcomes. The total outcomes are all the situations that could possibly happen. There are 52 cards in the deck, so there are 52 total outcomes. Next, the favorable outcomes are the outcomes we want. In this case it is drawing a 6. There are four 6's in a deck of cards: 6 of hearts, 6 of spades, 6 of diamonds, and 6 of clubs. This means there are 4 favorable outcomes.

We can write the probability as a fraction: $\frac{favorable-outcomes}{total-outcomes}$ , so we can get $\frac{4}{52}$ . Since both 4 and 52 are divisible by 4, the fraction can be simplified to $\frac{1}{13}$ .
