The circumference is about ___ cm.

i would really appreciate it thank you

Answer:

Step-by-step explanation:

122

Answer:

125.254..

Step-by-step explanation:

The triangles are 8 inches squared each, since it gives the length and width.

Since there are two triangles, it is 16.

The bottom is 4 by 8, which is 32, the back rectangle is 4 x 8 also, which is 32.

So we now have 32 + 32 + 16.

= 64 + 16

= 80

There is that last slant rectangle, which is harder.

We need to use pythagorean theorum to find that slant length first.\

4 ^ 2 + 4 ^2 = x ^2.

16 + 16 = 32.

32's squared root is something like 5.65685424949, but we will use 5.66.

Multiply that by 8 to get 45.254........

Add 80 + 45.254 = 125.254...

Round if the question tells you to, but this is an approximation due to decimals.

I took the same quiz as you and that is the final correct answer

Answer:

x = 85

Step-by-step explanation:

The Pythagorean theorem is a property that is specific to right triangles, or triangles with a right angle. The Pythagorean theorem states the following,

[tex]a^2 + b^2 = c^2[/tex]

Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.

Substitute in the given values and solve,

[tex]13^2 + 84^2 - x^2\\\\169 + 7056 = x^2\\\\7225 = x^2\\\\85 = x[/tex]

Got it right on brainly

The blue marble should be worth 8 points , Option C is the answer.

Probability is the likeliness of an event to happen.

Let the random variable is x ,

probability mass function is f(x) = P(X = x)

then The expectation of a random variable is determined by

E(x) = ∑(i =1 to n)    (  [tex]\rm x _i *f(x_i)[/tex] )

If the game has to be fair , the number of points that one can loose should be equal to the  number of points one can gain.

Probability of getting any color marble = 1/5 = 0.2

Let x be the total points scored in a game

and b be the number of points for blue coloured marble

Probability of choosing non-blue marble = 4/5 (points =-2)

Probability of choosing blue marble = 1/5 (points = b)

E(x) = -2 * (4*5) + b* (1/5)

The expectation will be zero as the total points balance out

0 = -8/5 + b/5

b = 8

Therefore the blue marble should be worth 8 points , Option C is the answer.

Step-by-step explanation:

The answer is 4 < x ≤ 10

Answer:

C

Step-by-step explanation:

Within the sentence, it explicitly states "the war was a vehicle for lasting social and economic gains." In other words, the war led to a better future in terms of social and economic gains for discriminated groups (discriminated groups were mentioned in the beginning of the sentence which gives us the who). Some may argue D is correct, but I strongly side with C instead because D emphasizes discrimination ended, while the sentence makes no such claim. The sentence only states discriminatory issues were improved, but still not completely absent. As for A, there is no mention of technology in the sentence. In terms of B, the sentence refers to the "gains" or improvement of discrimination and not the "plague" or worsening of discrimination. Hence, C fits best.

Answer:

30

Step-by-step explanation:

Well I think that this is a line, and so the angle is 180. The other line is 90 which is half of 180. It leaves 90 left. then all you have to do is solve the equation 3x=90 (x+2x=3, 9-9=0) 90 divided by 3 is 30.

Coral bleaching can be hazardous to some fish species because

A) coral reefs provide unique habitats for fish

B) decomposition of corals can lead to ocean acidification

C) the dead corals attract predators that feed on the fish

D) the corals are the primary source of O2O2 in ocean water

Solution:

Coral bleaching is process in which corals are stressed as a result of changes temperature, light, or nutrients causing them to turn completely white. Coral reefs are is a very diverse ecosystems with ecological and economic value.

Coral reefs are a very important habitat for the fishes providing home to about 25% of fishes. The coral reefs are used for shelter during the day, and as a hunting ground by night.

Answer:

A = 175, B = π/6, C = 345

Step-by-step explanation:

The given variation of the volume in the tank and time includes are;

At t = 0 the volume in the tank, y = Maximum volume, [tex]y_{max}[/tex] = 520 gallons

At t = 6 the volume in the tank, y = Minimum volume, [tex]y_{min}[/tex] = 170 gallons

The function that models the situation is y = A·cos(B·x) + C

Given that the function that models the situation is the cosine function, we have;

A = The amplitude = (The maximum - The minimum)/2

∴ A = (520 - 170)/2 = 175

A = 175

The period = The time to change from maximum to minimum = 2 × The time to change from maximum (t = 0) to minimum (t = 6)

∴ The period = 2 × (6 - 0) = 12

The period = 12 seconds = 2·π/B

∴ B = 2·π/12 = π/6

B = π/6

C = The vertical shift = Th minimum + A = (The maximum + The minimum)/2

∴ C = (520 + 170)/2 = 345

C = 345
