Aloha!
 First, add $20 and $20 and $20 and $20 because of the one $20 bill and the two ten dollar bills. 

Add the 10 quarters which is 2.50 and add 12 nickles 60 cents or .60 then add 2 pennies.
 The answer is $83.12 cents.
 Now divide that by 4 which is 20.78
 So to answer your question: 20.78 is how much each charity would get.
I hope this helps!:)

So if there are 3 $20, 2 $10, 10 $0.25, 12 $0.05 and $.02, it would add up to $83.12. If he splits this money evenly into 4 groups, it would be 83.12/4, which is 41.56/2, which simplifies to $20.78 per charity! :)

which of the following are NOT trigonometric identities, Check all that apply a.) sec^(2) x - tan^(2) x=1 b) sec^(2) x+csc^(2) x
Anit [1.1K]

By looking the given options, we can say that some of them are following pythagorean identities and pythagorean identities are

sin^2(x) + cos^2(x) =1, sec^2(x)-tan^2(x) =1,csc^2(x) -cot^2(x)=1

So out the four options, option a and option c are following pythagorean identity and option b and option d are not following pythagorean identity. And we have to find those options which are not identities .

So the correct options are

b) sec^{2} x+csc^{2} x=1 \ d) tan^{2} x + sec^{2} x =1

Whats answere y+2=-3 (x - 4)​
faust18 [17]

Answer:

 Slope = 6.000/2.000 = 3.000

 x-intercept = 10/3 = 3.33333

 y-intercept = -10/1 = -10.00000

Step-by-step explanation:

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -10.000 and for x=2.000, the value of y is -4.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -4.000 - (-10.000) = 6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

9. On a game show, there are 16 questions: 8 easy, 5 medium-hard, and 3 hard. If contestants are given questions
just olya [345]

Answer:

\frac{7}{30}\approx0.23

Step-by-step explanation:

Given:

Number of questions (N) = 16

Number of easy questions (E) = 8

Number of medium-hard questions (M) = 5

Number of hard questions (H) = 3

Now, the probability of getting the first question as easy question is given as:

P(E1)=\frac{\textrm{Number of easy questions}}{\textrm{Total questions}}\\\\P(E1)=\frac{E}{N}=\frac{8}{16}=0.5

Now, probability of getting the second question as easy question is given as:

P(E2)=\frac{\textrm{Number of easy questions left}}{\textrm{Total questions left}}\\\\P(E2)=\frac{E-1}{N-1}=\frac{7}{15}

Now, probability that the first two contestants will get easy questions is given by the product of P(E1)\ and\ P(E2). So,

P(2\ easy\ questions)=P(E1)\times P(E2)\\\\P(2\ easy\ questions)=\frac{1}{2}\times \frac{7}{15}\\\\P(2\ easy\ questions)=\frac{7}{30}\approx 0.23

Therefore, the probability that the first two contestants will get easy questions is \frac{7}{30}\approx0.23

Calculate a central angle in degree intercepting an arc of length 7 pi/2 cm in a circle with radius 77cm.​
sineoko [7]

The arc length of the circle exists 846.65922 cm.

<h3>How to estimate the central angle in degree? </h3>

A unit circle by definition contains a radius of 1 unit.

We have to estimate the length of the arc subtended by an angle of 7\pi/2 radians.

arc length = radius * angle

s = r$ * \theta

Where s be the arc length

r be the radius of the circle

\theta be the angle measured in radians

arc length = 77cm$*7\pi/2

arc length = 77 * 7(3.14) / 2

arc length = 846.65922 cm

Therefore, the arc length of the circle exists 846.65922 cm.
