Answer:

[tex]\text{b. }\sin \theta =\frac{3}{5}[/tex]

Step-by-step explanation:

In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. If [tex]\tan \theta =\frac{3}{4}[/tex] as given in the problem, then the opposite side of angle theta is 3 and its adjacent side is 4. Thus, the hypotenuse of the triangle must be [tex]h=\sqrt{4^2+3^2}=\sqrt{25}=5[/tex].

The sine of an angle in a right triangle is equal to its opposite side divided by its hypotenuse. Therefore, [tex]\sin \theta =\frac{3}{5}[/tex] (o/h).

x = 6

2x + 4= 2*6 + 4

2x + 4 = 12 + 4

2x + 4 =16

Charlies 16

hope it helps

Answer: he is 16

Step-by-step explanation:

Let x = Frank's age

2x+4+ = Charlie's age

x+3+ = Bob's age

9 = Bob's age

x+3=9

x=6

2x+4=2⋅6+4

2x+4=12+4

2x+4=16

Charlie is 16

Answer:

7x-15/5

Step-by-step explanation:

Given :-

And , we need to solve for y in terms of x . So taking the given equation ,

[tex]:\implies[/tex] 7x - 5y = 15

[tex]:\implies[/tex] -5y = 15 - 7x

[tex]:\implies[/tex] 5y = 7x - 15

[tex]:\implies[/tex] y = ( 7x - 15)/5

Answer:

Step-by-step explanation:

add all the numbers together to get your answer and divide it by two.

Answer:

Hello! answer: 12

Step-by-step explanation:

Assuming this is the Pythagorean theorem we would usually solve for c but c is already found so we have to work backwards so... 15 × 15 = 225

9 × 9 = 81 225 - 81 = 144 √144 = 12 therefore 12 is the answer Hope that helps!

Answer:

36 m 32 s

Step-by-step explanation:

67 /110 = 0.609 hour

0.609 × 60 minutes = 36.54 minutes

Answer:

81/792 or 9/88 or 10.2%

Step-by-step explanation:

Possibility: nCr(12,5) = 792
Red: nCr(3,2) = 3
Blue, Green, White: nCr(3,1) = 3

3 * 3 * 3 * 3 = 81

81/792 simplified is 9/88 percentage is 10.22%

The probability that Jamal will catch 2 red balls and 1 ball of each of the other colors is 0.1025.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lies in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The total numbers of balls are 12.

Each color has 3 balls.

If total 12 balls are tossed, the number of ways of catching 5 of them is,

¹²C₅ = 792

The number of ways of catching 2 red balls out of 3 is ³C₂ = 3

The number of ways of catching 1 green ball out of 3 is ³C₁ = 3

The number of ways of catching 1 blue ball out of 3 is ³C₁ = 3

The number of ways of catching 1 white ball out of 3 is ³C₁ = 3

Thus, the probability as per the question is given as follows,

(3 × 3 × 3 × 3)/792

= 81/792

= 0.1025

Hence, the probability of catching 2 red balls and 1 ball of each of the other colors is 0.1025.

Answer:

0.1057

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score = 32 oz

μ is the population mean = 33 oz

σ is the population standard deviation = 0.8oz

For x < 32 oz

z = 32 - 33/0.8

z = -1.25

Probability value from Z-Table:

P(x<32) = 0.10565

Approximately = 0.1057

Therefore, the proportion of packets that are underweight (i.e. Weight less than 32 oz.) are 0.1057.

Answer:

y=2x-1

Step-by-step explanation:

If you are supposed to write the equation in slope-intercept format, (y=mx+b), then y=2x-1 would be the answer. 2 is the slope(m), and -1 is the y-intercept(b). I hope thus helped :).

Answer:

83 ounces

Step-by-step explanation:

2 lb 11 oz + 2 lb 8 oz = 4lb 19oz

REMEMBER: 1 pound = 16 oz

4 lb x 16 = 64 oz

64 oz + 19 oz = 83 oz

Answer:

260m

$73.2

Step-by-step explanation:

For what amount of driving do the plans cost the same?  

 What the cost when the two plans cost the same?

first plan = 42 + 0.12m

second plan = 55 + 0.07m

42 + 0.12m  =  55 + 0.07m

collect like terms

55 - 42 = 0.12 - 0.07m

13 = 0.05m

m = 260

42 + 0.12(260) = 73.2

Answer:

2 + 1 1/3x ≥ 6

x ≥ 3 days

Step-by-step explanation:

Monday = 2 miles

Other days = 1 1/3 miles

x = least number of days after Monday that Joseph needs to run

to reach his goal

Total miles = 6 miles

The inequality is

2 + 1 1/3x ≥ 6

1 1/3x ≥ 6 - 2

1 1/3x ≥ 4

4/3x ≥ 4

Divide both sides by 4/3

4/3x ÷ 4/3 ≥ 4 ÷ 4/3

x ≥ 4 × 3/4

x ≥ 3 days

Answer:

[tex]\implies y = \dfrac{1}{2}x + 1 [/tex]

Step-by-step explanation:

Given :-

And we need to find out the equation of the line passing through the given two points .So here we can use the two point form of the line as ,

[tex]\implies (y - y_1) = \dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]

Let us take that ,

Now substitute the respective values ,

[tex]\implies (y -3) =\dfrac{3+1}{4+4}(x-4) \\\\\implies y - 3 =\dfrac{4}{8}(x-4) \\\\\implies y -3=\dfrac{1}{2}(x-4) \\\\\implies y -3=\dfrac{1}{2}x - 2 \\\\\implies y = \dfrac{1}{2}x +3-2\\\\\implies y = \dfrac{1}{2}x + 1 [/tex]

Hence the correct option is (2) .

Step-by-step explanation:

Answer:

B. (2x + 10)(2x + 9)

Step-by-step explanation:

Length (L) of the garden and walkway = x + 10 + x = (2x + 10) ft

Width (W) of the garden and walkway = x + 9 + x = (2x + 9)

Area of the garden and walkway = area of rectangle = L*W

= (2x + 10)(2x + 9)

The polynomial representing the total area of the garden and walkway = (2x + 10)(2x + 9)
