The Measures Of The Angles Of A Triangle Are Shown In The Figure Below. Solve For X.(8x-9)6370

Answers

Answer 1

Answer:

x= 7

Step-by-step explanation:

Theorem:  The sum of the angles of a triangle is 180

Memorize that theorem

8x - 9 + 63 + 70 = 180

8x + 124 = 180

8x = 56

x= 7

To track the reptile population around a lake, researchers marked 36 turtles. A few weeks later, they counted 400 turtles, of which 20 were marked. To the nearest whole number, what is the best estimate for the turtle population?

Answers

Answer: 720

Step-by-step explanation:

From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.

If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:

1/20 × x = 36

x/20 = 36

x = 20 × 36

x = 720

The turtle population is 720

Hope this helps!

Please give me the correct answer.Only answer if you're very good at math.Please don't put a link to a website.​

Answers

Answer:

there are infinitely many solutions

LEFT SIDE/ LEFT EQUATION: if you multiply 1 and (b + 14) together, the result becomes the numerator of the fraction (with 2 being the denominator).

Once you do that, you will notice that both sides/both equations are exactly the same.

Thus, if you put in ANY number for variable b, the solution of both sides/both equations will always be the same and work.

The answer is: "There are infinetly many solutions"

Answer:

B

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

122° is an exterior angle to both triangles , then

∠ 1 + 75° = 122° ( subtract 75° from both sides )

∠ 1 = 47°

and

∠ 2 + 88° = 122° ( subtract 88° from both sides )

∠ 2 = 34°

Answers

Answer:

6 * 10^2

Step-by-step explanation:

Simplify : (4.2×10^7)÷(7×10^4)

(4.2 × 10^7) / (7 × 10^4)

From indices : 10^a ÷ 10^b = 10^(a - b)

(4.2 / 7) * 10^(7-4)

0.6 * 10^3

= 6 * 10^2

Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2

8 in approx

Step-by-step explanation:

Given data

volume = 100 cubic inches

radius= 2 inches

The expression for the volume of a cylinder is given as

v=πr^2h

substitute

100= 3.14*2^2h

100= 12.56h

h= 100/12.56
