x + y = -50
y = 4x

Answer (x,y)

Answers

Answer:

x = -10 ; y = -40

Step-by-step explanation:

Note:

y = 4x.

Plug in 4x for y in the first equation:

x + y = -50

x + (4x) = -50

Solve for x. First, simplify, then isolate the variable, x.

x + 4x = -50

5x = -50

Divide 5 from both sides of the equation.

(5x)/5 = (-50)/5

x  = -50/5

x = -10

Plug in -10 for x in one of the equations:

y = 4x

y = 4(-10)

y = -40

x = -10 ; y = -40 is your answer.

Answers

Answer:

9y+3

Step-by-step explanation:

you add all the common numbers and you end up with:

9y^6+3+y^-5

then you put the y^-5 under the other numbers and make it positive so it becomes:

9y^6+3/y^5, then you subtract the exponents of y: 6-5, so that cancels out the y on the bottom making it:

9y+3

Answers

Answer:

1,2,5

Step-by-step explanation:

The first pattern has a difference of 5 while the second is 10 and become by multiplying 2 in pattern 1 so options (A),(B), and (E) will be correct.

What is the pattern?

A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.

The hint which is present in a given pattern hides in the pattern only.

For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.

Another example is 2,4,16,256 in this pattern each term is the square of the previous term and this will become its specific pattern.

Given the two patterns.

In the first pattern, each term become by adding 5 so option (A) is correct.

In the second pattern, each term become by adding 10 so option (B) is correct.

The term in the second pattern becomes by multiplying 2 in pattern 1

For example 5× 2 = 10 and 10 × 2 = 20 so option (E) will be correct.

Hence "The first pattern has a difference of 5 while the second is 10 and become by multiplying 2 in pattern 1".

A projectile is launched from ground level with an initial velocity of 89 ft/sec. It's height(ft), t seconds after launching is given by s=-16t^2 + v0t + s0. a) Fine the time(s) the projectile will reach a height of 100 feet. b) find the time it takes the projectile to hit the ground

Answers

Answer:

Step-by-step explanation:

Initial Velocity of projection = 89ft/sec

height(ft), t seconds after launching is given by s=-16t^2 + v0t + s0

A) time the projectile will reach a height of 100 ft

s=-16t^2 + v0t

v0 = 89ft/sec

s = 100ft

100 = - 16t² + 89t

-16t² + 89t - 100 = 0

Answer:

500

Step-by-step explanation:

20% of x = 100

Write 20% as a decimal - - > 0.2(x) = 100

Isolate and solve for x - - > x = 100/0.2

Therefore, x = 500

Answer:

500

Step-by-step explanation:

Let the no. be x

20% of x = [tex]\frac{20}{100} x[/tex]

And ,

[tex]\frac{20}{100} x = 100\\=> 20x = 10000\\ => x = \frac{10000}{20} = 500[/tex]

Jamie will choose between two catering companies for an upcoming party. Company A charges a set up fee of $500 plus $25 for each guest. Company B charges a set up fee of $200 dollars plus 30per guest. How many guests are need where the price is equal

Answers

Answer:

60 guests

Step-by-step explanation:

We'll say that the number of guests is n.

We're looking for the n where both of these expressions are equal:

Company A (500 set-up fee, 25 for each guest)

500 + 25 * n

Company B (200 set-up fee, 30 for each guest)

200 + 30 * n

500 + 25n = 200 + 30n

Subtract 200 from both sides.

300 + 25n = 30n

Subtract 25n from both sides.

300 = 5n

We'll reverse the sides.

5n = 300

Divide both sides by 5.

n = 300/5 = 60

Thus, both companies are equal when n is 60, or when there are 60 guests.

what does x = in this equation? 7x-2+2x+14=33

Answers

Answer:

x = 7/3

Step-by-step explanation:

First, combine like terms:

7x + 2x - 2 + 14 = 33

(7x + 2x) + (14 - 2) = 33

9x + 12 = 33

Isolate the variable, note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 12 from both sides:

9x  + 12 (-12) =  33 (-12)

9x = 33 - 12

9x = 21

Next, divide 9 from both sides:

(9x)/9 = (21)/9

Simplify. Divide common factors:

x = (21/9)/(3/3) = 7/3

x = 7/3

You flip a fair coin until you see three tails in a row. What is the average number of headsthat you’ll see until gettingTTT?

Answers

Answer:

14

Step-by-step explanation:

From the given information:

suppose, Y is the number of times a coin is being flipped.

If the coin is flipped for the first time and we get H, then we have:

TTT = [tex]\dfrac{1}{2}(Y+1)[/tex]

Afterward, if we get H, then we waste two times plus the probability of this event [tex]\dfrac{1}{4}[/tex].

Therefore, we have : [tex]\dfrac{1}{4}(Y+2)[/tex]

Afterward, if we get H, then we waste three times plus the probability of this event [tex]\dfrac{1}{8}[/tex].

Therefore, we have : [tex]\dfrac{1}{8}(Y+3)[/tex]

If we got T at the third time, then;

T = [tex]\dfrac{1}{8}(3)[/tex]

Thus, average number of headsthat you’ll see until gettingTTT can be expressed as:

[tex]= \dfrac{1}{2}(Y+1)+ \dfrac{1}{4}(Y+2)+ \dfrac{1}{8}(Y+3)+ \dfrac{1}{8}(3)[/tex]

4. Ariel loves to go to baseball games. This season she has already attended 23 New York Ducks games. If
Ariel attended nine more weekend games than weekday games, how many weekday games did she attend.

Answers

Answer: She attended to 7 weekday games.

Step-by-step explanation:

Let's denote our variables as:

Wd = number of weekday games that she attended.

We = number of weekend games that she attended.

We know that in total, she attended to 23 games, so we have:

Wd + We = 23.

"If  Ariel attended nine more weekend games than weekday games" can be written as:

We = Wd + 9.

Then we have the system of equations:

Wd + We = 23.

We = Wd + 9.

The first step would be to replace the second equation into the first one, as:

Wd + We = 23.

Wd + (Wd + 9) = 23

Now we can solve this for Wd.

2*Wd + 9 = 23

2*Wd = 23 - 9 = 14

Wd = 14/2 = 7

She attended to 7 weekday games.

And:

We + 7 = 23

We = 23 - 7 = 16

She attended at 16 weekend games.

Gummi bears come in twelve flavors, and you have one of each flavor. Suppose you split your gummi bears among three people (Adam, Beth, Charlie) by randomly selecting a person to receive each gummi bear. Each person is equally likely to be chosen for each gummi bear.
(a) What is the probability that Adam gets exactly three gummi bears?
(b) If you know that each person recieved at least one gummi bear, what is the probability that Adam gets exactly three gummi bears?
(c) What is the expected number of gummi bears that Adam gets?
(d) If you know that each person recieved at least one gummi bear, what is the expected number of gummi bears that Adam gets?
(e) Is there more variance in the number of gummi bears that Adam gets with or without knowing that everyone gets at least one gummi bear? Explain your answer without calculations.

Answers

Step-by-step explanation:

From the given gummi bear, the chance that Adam is selected for any draw is 1/3 as well as the chance he is not selected at any draw is 2/3.

a). The probability of Adam getting exactly three gummi bears = P(Adam gets selected at 3 draws and not selected at the remaining 9 draws)

= [tex]$ (\frac{1}{3})^3 (\frac{2}{3})^9 = \frac{2^9}{3^{12}} $[/tex]

Now, the 3 draws where Adam gets selected can be any 3 out of 12 draws in [tex]$ {\overset{12}C}_3 $[/tex] = 220

Thus, probability of Adam getting three gummi bears = [tex]$ 220 \times \frac{2^9}{3^{12}} $[/tex]

                                                                                                = 0.21186

b). Probability that Adam will get the three gummi bears given each person will received at the most 1 gummi bear

= P(of the remaining 9 draws after assigning one gummi bear to each one, Adam gets selected at 2 draws and not selected at 7 draws) = [tex]$ {\overset{9}C}_2 (\frac{1}{3})^2 (\frac{2}{3})^7 $[/tex]

                                                                                               = 0.23411

c). Let X = Number of the gummi bears which Adam will get. Then, X = number of draws out of 12 draws Adam gets selected and X ~ B(12, 1/3). So,  Adam will get gummi bears= mean of B(12, 1/3) = 12 x (1/3) = 4

d). Let Y = Number of the gummi bears that Adam will get, given each person will received at the most 1 gummi bear Then, Y = number of draws Adam gets selected in the remaining 9 draws and Y ~ B(9, 1/3). So, the expected number of bears that Adam gets given each person received at least 1 gummi bear

= 1 + mean of B(9, 1/3) = 4

e). When every one gets atleast one gummi bear, the new sample size will be 9 and so we can say that there is a reduction in variance.

Answers

Answer:

A= 29

B=34

C=117

A + B + C = 180

B = A + 5

C = 4A + 1

Plug in.

A + A + 5 + 4A + 1 = 180

6A + 6 = 180

6A = 174

A = 29

Now since you found A, find the other two by plugging A in!

C = 4(29) + 1

C = 117

Plug in the B equation

B = 29 + 5

B=34

Community Gym charges a $55 membership fee and a $40 monthly fee. Workout Gym
charges a $125 membership fee and a $30 monthly fee. How many months will it take for
the cost of both gyms to be the same? and what is the cost of the gyms during that number
of months?

Answers

The gyms can be represented by these equations, with x for months. 40x+55= 30x+125. Combine like terms. First, subtract 30x from both sides, and you get 10x+55=125. Subtract 55 next. You now have 10x=70. Divide by 10, and you get x=7. It will take 7 months for them to be the same. To find the cost, you can plug in x. 40(7)+55=335. 30(7)+125=335. The cost is $335.
