Your local radio station is having their yearly music player and concert ticket giveaway. For one minute, every 5th the caller will win a music player and every 7th caller will win concert tickets.

You were just the first caller to win both a music player and concert tickets!

What number of caller were you?

Answers

Answer:

you are the 35th caller.

Step-by-step explanation:

Multiples of 5: 5,10,15,20,25,30,35,40,45,50

Multiples of 7: 7,14,21,28,35,42,49,56,63,70

Since the question specified "first caller" , the answer is basically from the lowest common Multiple (the lowest number that appear in both multiples) , and in this case, only 35 is the lowest common multiple.

Solve for x please :).

x= 4. To find the perimeter you add all the sides. One side is 6 so the other has to be six as well because there are 2 pairs of congruent sides in a rectangle. 20-12=8 and now you divide by two to find the value of the two sides left

how many possibilities are there if you toss coin 7 times

Answers

each toss results in 2 possible outcomes, head or tail so the number of possible outcomes for 7 would be

Answer:

2^7

2x2x2x2x2x2x2 = 2^7

2^7 because each time you flip the coin there can be two outcomes (heads or tails) and you have to multiply by 2 each time (2x2x2x2x2x2x2) to account for all the different possibilities for instance you could flip heads, tails, heads, heads, tails, tails, tails or you could flip tails, tails, tails, heads, heads, tails, heads or all heads or all tails which is why it’s 2^7

Step-by-step explanation:

There are many ratios equivalent to 3:4. For example, 6:8, 9:12, 12:48, 15:20, 18:24

Step-by-step explanation:

The formula to calculate the gravitational force between two objects is F_g=GM_1M_2/r^2, where M_1 and M_2 are the masses of the objects, G is the gravitational constant and r is the distance between the objects. Solve for M_1 in terms of F_g, G, M_2 and r.

Answers

Answer:

[tex]M_{1}[/tex] = [tex]\frac{F_{g}r^{2} }{GM_{2} }[/tex]

Step-by-step explanation:

From Newton's law of universal gravitation, the force of attraction between two objects of masses [tex]M_{1}[/tex] and [tex]M_{2}[/tex] is given as:

[tex]F_{g}[/tex] = [tex]\frac{GM_{1} M_{2} }{r^{2} }[/tex]

Thus, cross multiply to have;

[tex]F_{g}[/tex][tex]r^{2}[/tex] = G[tex]M_{1}[/tex][tex]M_{2}[/tex]

then divide through by G[tex]M_{2}[/tex] to have,

[tex]M_{1}[/tex] = [tex]\frac{F_{g}r^{2} }{GM_{2} }[/tex]

Therefore, [tex]M_{1}[/tex] can be expressed in terms of [tex]F_{g}[/tex], [tex]r^{2}[/tex], G, [tex]M_{2}[/tex] as [tex]\frac{F_{g}r^{2} }{GM_{2} }[/tex]

Please help me solve :(((

Answers

Answer:

θ ≈ 15°

Step-by-step explanation:

Using the sine rule in the triangle

note 7.56 × 10² = 756 and 2.4 × 10³ = 2400 , then

[tex]\frac{756}{sin0}[/tex] = [tex]\frac{2400}{sin125}[/tex] ( cross- multiply )

2400 × sinθ = 756 × sin125° ( divide both sides by 2400 )

sinθ = [tex]\frac{756sin125}{2400}[/tex] , then

θ = [tex]sin^{-1}[/tex] ( [tex]\frac{756sin125}{2400}[/tex] ) ≈ 15° ( to the nearest degree )

Step-by-step explanation:

First, since the a cancel eachother out we are left with (4-b) + (-6-7)

Second, you want to add the -6 and -7 to get -13, so (4-b) - 13

Finally, add the 4 to the negative 13 to get (-b - 9)

9. A bag of M&M's contains 4 red, 1 blue, 3 yellow, and 2 brown. What is the probability
of Maggie choosing a yellow M&M, eating it, and then choosing another yellow M&M?

Answers

Answer:

1/15

Step-by-step explanation:

Given that:

Total Number of M&M's = (4 + 1 + 3 + 2) = 10

Number of yellow M&M's = 3

Probability = required outcome / Total possible outcomes

First pick (choosing without replacement)

P(choosing a yellow M&M) = 3 / 10

Second pick :

P(choosing a yellow M&M) = 2 / 9

P(choosing 2 yellow M&M) = 3/10 * 2/9 = 6/90 = 1/15

Find the y-intercept of 2x - y = -6.

Answers

B is correct 12 for find the y-intercept of 2x-y=-6
I’m pretty sure it’s -6 because

To find y-intercept, you have to substitute x=0

2 * 0 - y = 6

Then you solve the equation for y

2 * 0 =

0 - y

So your answer is

Y = -6
