This is an isosceles right triangle < M =90°, < L = 45°, then < K = 45°

Hence LM =KM =5. Pythagoras:

LK² = LM² + KM²

LK² = 5² + 5²

LK² = 25 + 25

LK² =50 AND LK =√50 OR =√25x2 or = 5√2

The citizens of a certain community were asked to choose their favorite pet. The pie chart below shows the distribution of the c

Arturiano [62]

Incomplete Question:

The content of the pie chart is as follows:

Hamsters = 9% ; Snakes = 10% ; Cats = 23%

Birds = 21% ; Dogs = 26% ; Fish = 11%

Answer:

The number of citizens who chose cat or fish is 47,600

Step-by-step explanation:

Given

Number of citizens = 140,000

Required

Determine the number of those that chose fish or cats

First, we need to calculate the percentage of those whose pets are either cats or fish

$Percentage = Cat + Fish$

Substitute 23% for cat and 11% for fish

$Percentage = 23\% + 11\%$

$Percentage = 34\%$

Next, is to multiply the calculated percentage by the number of citizens

$Cat\ or\ Fish = Percentage * Number\ of\ Citizens$

$Cat\ or\ Fish = 34\% * 140000$

$Cat\ or\ fish = 47600$

Hence, the number of citizens who chose cat or fish is 47,600

Joe nas to take two quizzes tomorrow. He nas only enough time to study one of them. • The science quiz has 7 true-or-false quest

Nostrana [21]

Answer:

Step-by-step explanation:

Science questions are T/F. That's .5 or $\frac{1}{2}$ chance to get it right.

7 questions. Each with a $\frac{1}{2}$ .

That's $(\frac{1}{2})^{7}$

$(\frac{1}{2})^{7}$ = $\frac{1}{128}$ = .0078 = .008 rounded

English questions are multiple choice. 4 choices. That's .25 or $\frac{1}{4}$

3 questions. Each $\frac{1}{4}$

That's $(\frac{1}{4})^{3}$

$(\frac{1}{4})^{3}$ = $\frac{1}{64}$ = .0156 = .016 rounded

PLEASE HELP I WILL MARK!!

Rina8888 [55]

answer is D

Explamation:

given points are (7,9) and (12,11)

$mid \: point \: of \: x = \frac{x1 + x2}{2 } = \frac{7 + 12}{2} = 9.5 \\ midpoint \: of \: y = \frac{y1 + y2}{2} = \frac{9 + 11}{ 2} = 10$

therefore the mid point is (9.5,10)
