Answer:

$60

Step-by-step explanation:

Answer:

$60

Step-by-step explanation:

This is the answer because:

1) $12t = total cost

2) t = tickets, 5 = tickets

3) $12 x 5 = $60

Therefore, the answer is $60.

Hope this helps! :D

Look at the graph, its a pattern. The number of weeks is Times 2 every time, therefore 10 *2 is 20, and the number of players are getting close

Answer:

there is an 86% change

Answer:

4. a. y = 2x

b. she will need 12 packs of cashews to 24 cans of peanuts to make the mix.

5. a. YES

b. y = 2.5x

c. $30

d. 24 pounds

e. See attachment

Step-by-step explanation:

4.a. packages of cashews = x

Cans of peanuts = y

The equation that represents the relationship between x and y can be expressed in slope-intercept form as y = mx

Slope = m,

Finding slope (m) using two pairs (1, 2) and (2, 4):

Slope = ∆y/∆x = (4 - 2)/(2 - 1) = ²/1 = 2

m = 2.

To write the equation, substitute m = 2 into y = mx

The equation would be:

y = 2x

b. The ordered pair (12, 24) in the context of the problem means she will need 12 packs of cashews to 24 cans of peanuts to make the mix.

5. a. The cost of candy is proportional to the amount of candy because: 5/2 = 7.5/3 = 12.5/5 = 2.5 = constant of proportionality/unit rate

b. An equation can be written to show the proportional relationship in the form of y = mx.

Where, m = constant of proportionality/unit rate

x = amount of candy

y = cost on dollars

Thus, substitute m = 2.5 into y = mx

The equation would be:

y = 2.5x

c. To find how much it would cost (y) for 12 pounds of candy (x), substitute x = 12 into y = 2.5x to find y.

Thus:

y = 2.5(12) = 30

It would cost $30 for 12 pounds of candy

d. To find the maximum amount of candy (x) you can buy with $60 (y), substitute y = 60 into y = 2.5x

Thus:

60 = 2.5x

Divide both sides by 2.5

60/2.5 = 2.5x/2.5

24 = x

x = 24

Maximum amount of candy you can buy with $60 is 24 pounds of candy.

Answer:

P(both students passed the exam) = 0.61948

Step-by-step explanation:

From the given information:

P(both students passed the exam) = P(both are science students or both are art major students or one is from each group)

= P (both are science students) + P(both are art students) + P(one from each group)

where;

P (both are science students) = (50/100) (0.9) × (44/99) × (0.9) = 0.18

P(both students are art) = (50/100) (0.7) × (49/99) 0.7 = 0.1213

P(one of the student are from each group) = (50/100) (0.9) ×(50/99) (0.7) + (50/100) (0.7)× (50/99)(0.9) =0.3182

P(both students passed the exam) = 0.18 + 0.1213 + 0.3182

P(both students passed the exam) = 0.61948

The volleyball team is selling 700 snack bags to raise money.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Sales of pretzels and cheese puffs represent 30% of overall sales, which means that 210 bags were sold.

This ratio could be established,

⇒ 210/30% = x/100%

⇒ x = (210)100%/30%

⇒ x = 70×10

⇒ x = 700

Thus we could evaluate that there are 700 bags in total.

Therefore, the volleyball team is selling 700 snack bags to raise money.

We know that ,

[tex] \sin( \alpha ) = \frac{opposite}{hypotenuse} [/tex]

and

[tex] \cos( \alpha ) = \frac{adjacent}{hypotenuse} [/tex]

where 'alpha' is an angle of triangle ; 'opposite' denotes the side opposite to alpha & 'adjacent' refers to the side next to the angle (but not hypotenuse)

Similarly ,

[tex] \sin(q) = \frac{opposite}{hypotenuse} = \frac{4}{5} [/tex]

Let the length of the opposite side be 4x and the length of hypotenuse be 5x. By using Pythagorean Theorem , we can find the length of base.

[tex] {base}^{2} + {(4x)}^{2} = {(5x)}^{2} [/tex]

[tex] = > {base}^{2} = 25 {x}^{2} - 16 {x}^{2} = 9 {x}^{2} [/tex]

[tex] = > base = \sqrt{9 {x}^{2} } = 3x[/tex]

Now , we have got the length of all the sides of the triangle. So,

[tex] \cos(q) = \frac{adjacent}{hypotenuse} = \frac{3x}{5x} = \frac{3}{5} [/tex]

and

[tex] \cos(p) = \frac{adjacent}{hypotenuse} = \frac{4x}{5x} = \frac{4}{5} [/tex]

So,

[tex] \cos(p) + \cos(q) = \frac{4}{5} + \frac{3}{5} = \frac{7}{5} [/tex]
