Step-by-step explanation:

a)

sample space is basically all possible outcomes in a list so {1H,2H,3H,4H,5H,1T,2T,3T,4T,5T}

b)

favorable outcomes of choosing an odd number are the outcomes with odd numbers so 1H,3H,5H,1T,3T,5T

sin 30 = x/(18-x)

1/2 = x/(18-x)

18-x = 2x

3x = 18

x = 6

Use the value of the ratio to determine which ratios are equivalent to 7: 15.
Alexandra [31]

Answer:

a. 21: 45

d. 63: 135

Step-by-step explanation:

Ratio or Relationship of two quantities is the result of comparing two quantities.

Such a comparison could be indicated as a reason, in four different ways, in this way:

1)a: b

2)a ÷ b

3)a/b

d)The reason for a is a b.

Equivalent ratios can be used to show the same relationship between two quantities. Remember that the word "equivalent" means the same.

Problem development

We observe what are the equivalent relationships 7:15 and conclude that they are the following:

a.To find the equivalent ratio, we divide the numerator and denominator by the same number , In this case we divide by 3:

21: 45 = 21/45 = 21÷3 /45÷3 = 7/15

d.To find the equivalent ratio, we divide the numerator and denominator by the same number , In this case we divide by 9:

63: 135= 63/135 = 63÷9 /135÷9= 7/15

Two angles of a triangle are 30°and 80°. Find the third angle.
stiv31 [10]

Answer:

The third angle of the triangle is 70°.

Step-by-step explanation:

The two angles of a triangle (say Δ ABC) are given to be 30° and 80°.

We have to find the third angle.

Let us assume that ∠ A = 30° and ∠ B = 80°, then we have to find ∠ C.

Now, we know that, ∠ A + ∠ B + ∠ C = 180° {Property of a triangle}

⇒ 30° + 80° + ∠ C = 180°

⇒ ∠ C = 180° - 30° - 80° = 70°

Therefore, the third angle of the triangle is 70°. (Answer)

Cost of 1 plant = $ p

Cost of 4 plants = $(4p)

Cost of a 10-gallon tank = $10

Cost of a water dish = $3

Total cost = 4p + 10 + 3 = 4p + 13
