Answer:

Cos Y = 12/13

Step-by-step explanation:

Recall, SOHCAHTOA.

Cos Y = Adjacent/Hypotenuse

Reference angle = Y

Adjacent = 12

Hypotenuse = 13

Therefore:

Cos Y = 12/13

Answer:

The height on the map is of 12 inches.

Step-by-step explanation:

Scale of 1 inch:300 meters

This means that each inch on the map represents 300 meters of real height.

If the actual height of one of those mountains is 3,600 meters, what is its height on the map?​

Using proportions, by a rule of three:

1 inch - 300 meters

x inches - 3600 meters

Applying cross multiplication:

[tex]300x = 3600[/tex]

[tex]x = \frac{3600}{300}[/tex]

[tex]x = 12[/tex]

The height on the map is of 12 inches.

a = 12√3

b = 24

Answer:

$19,500 - $1000

Step-by-step explanation:

the amount Brianna earns in excess of the amount Lisa earns can be determined by subtracting the amount Brianna earns from that Lisa earns

$19,500 - $1000 = $18,500

Answer:

45

Step-by-step explanation:

1. $70 + $110 = $180

2. $180 ÷ 4 = $45/hour

Answer:

The original price of the shoes was $90.

Step-by-step explanation:

25% off means the price Joe paid for it is 75% of the original price.

Set up an equation:

75/100 = 67.50/x

Cross multiply

75 × x = 100 × 67.50

75x = 6750

x = 90

Check our work:

First solve for 25% off of 90 (our answer).

25% = 0.25

90 × 0.25 = 22.50

Next, subtract the discount from 90.

90 - 22.50 = 67.50

67.50 was what Joe paid so this is correct.

Answer:

b. False

Step-by-step explanation:

The law of large numbers, in statistics, says that the experimental average found in a large number of trials should be very close to the theoretical probability. It does not say anything about distribution. So the answer to this question is False, which is given by option b.

Answer: I think its C (12/25) I'm not completely sure though.

Step-by-step explanation:

Step-by-step explanation:

Given :-

The length of the garden 8m greater than 2 times the width.

Area of the garden is 280 m²

Let us consider the length as x and width as y.

Sp, we can day length as :-

x = 8 + 2y ---(1)

Now, we know that:-

Area of Rectangle = Length × Breadth

280 = x * y

We can replace the value of x now,

280 = y × ( 8 + 2y)

280 = 8y + 2y²

2y² + 8y - 280 = 0

y² + 4y - 140 = 0

Factorise it.

(y -10)(y + 14)

Cancelling -ve value, we get the width as 10 metres.

Hope it helps :)

Answer:

Step-by-step explanation:

Width = w

Length = 2w + 8

Area of rectangular garden = 280 square meter

length * width = 280

(2w + 8 ) *w = 280

2w * w + 8*w = 280

2w² + 8w = 280

2w² + 8w - 280 = 0

Divide the whole equation by 2

w² + 4w - 140 = 0      

w² + 14w - 10w - 14 *10 = 0

w(w + 14) - 10(w + 14) = 0

(w + 14)(w - 10)= 0

w - 10 = 0       {Ignore w + 14, as measurements will not be -ve}

w = 10 m

l = 2*10 +8

= 20 +8

l  = 28 m

The .79 correlation is strong and positive, but "significan" is a question not answered by the correlation coefficient.  Many people mistake correlation for causation--one variable's change causing the other variable to change.

Answer:

y = -2x + 5

Step-by-step explanation:

Points on the path: (0, 5) and (1, 3)

Slope:

m=(y2-y1)/(x2-x1)

m=(3-5)/(1-0)

m= (-2)/1

m= -2

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = -2(x - 0)

y - 5 = -2x

y = -2x + 5

Following are the responses to the given question:

Step-by-step explanation:

Given:

[tex]\to f(x,y)=xy\\\\\to 48x^2+3y^2=3456\\\\[/tex]

let [tex]\phi(x,y)=48x^2+3y^2=3456[/tex]

using the lagrange multiplies:

[tex]\bigtriangledown f=\lambda \bigtriangledown \phi\\\\i)\ \ y=96 \lambda x \to \lambda=\frac{y}{96\ x} \\\\ii)\ \ x=6 \lambda y \to \lambda=\frac{y}{6\ y} \\\\iii)\ \ 48x^2+3y^2=3456\\\\[/tex]

From equation (i) and (ii)\\\\

[tex]\to \frac{y}{96x}=\frac{x}{6y}\\\\\to 6y^2=96x^2\\\\\to 3y^2=48x^2\\\\[/tex]

From equation 3:

Answer:

y = 658.3 ft

Step-by-step explanation:

Angle of depression = angle of elevation = 28° (alternate angles are congruent)

Reference angle = 28°

Side length opposite to reference angle = 350 ft

Adjacent = y

Apply trigonometric function, TOA:

Tan 28 = Opp/Adj

Tan 28 = 350/y

y*Tan 28 = 350

y = 350/Tan 28

y = 658.254263 ≈ 658.3 ft (nearest tenth)
