A helicopter hovers 500 feet above a small island. The figure shows that the angle of
depression from the helicopter
to point P is 49º. How far off
the coast, to the nearest foot, is the island?

Answer: b, d

Step-by-step explanation:

Corresponding angles are formed when two parallel  straight lines are cut by a transversal

[tex]\angle b=62^{\circ}[/tex]

In the figure, [tex]\angle d\ \text{and}\ 62^{\circ}[/tex] are alternate angle

[tex]\therefore \angle d=62^{\circ}[/tex]

Answer:

A

Step-by-step explanation:

Because if you subtract A from A it gets rid of A leaving only B left.

Answer:

0.57

Step-by-step explanation:

The 7 is in the hundredths place. Next to it is a 4. 4 does not round up, therefore making the answer 0.57.

Answer:

A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.

Step-by-step explanation:

Given

[tex]3x - 3y = 1[/tex]

[tex]-2x+ 4y = 2[/tex]

Required

A good first step

A good first step is to eliminate x and this is done as follows:

Multiply [tex]3x - 3y = 1[/tex] by 2 (gotten from coefficient of x in the second equation)

Multiply [tex]-2x+ 4y = 2[/tex] by 3 (gotten from coefficient of x in the first equation)

This gives:

[tex]6x - 6y = 2[/tex]

[tex]-6x + 12y = 6[/tex]

Add both equations

[tex]6x - 6x - 6y + 12y = 2 + 6[/tex]

[tex]6y = 8[/tex]

[tex]y = \frac{4}{3}[/tex]

Hence (a), is true

Answer:

1,440,000

Step-by-step explanation:

1249 is rounded to 1200 because 49 is less than half of 100.

1194 is rounded to 1200 because 94 is more than half of 100.

1200 x 1200 = 1,440,000

Answer:

sin 15° = 0.2588

Step-by-step explanation:

The half angle formula is:

[tex]\sin{(\frac{x}{2})} = \pm \sqrt{\frac{1 - \cos{x}}{2}}[/tex]

sin 15°

The double of 15º is 30º. First quadrant, so the sine is positive.

[tex]\sin{15} = sqrt{\frac{1 - \cos{30}}{2}}[/tex]

Since [tex]\cos{30} = 0.866[/tex]

[tex]\sin{15} = sqrt{\frac{1 - \cos{30}}{2}} = \sqrt{\frac{1 - 0.866}{2}} = 0.2588[/tex]

sin 15° = 0.2588

Answer:

There are no solutions

Step-by-step explanation:

9x+18−5x=2+4x

Step 1: Simplify both sides of the equation.

9x+18−5x=2+4x

9x+18+−5x=2+4x

(9x+−5x)+(18)=4x+2(Combine Like Terms)

4x+18=4x+2

4x+18=4x+2

Step 2: Subtract 4x from both sides.

4x+18−4x=4x+2−4x

18=2

Step 3: Subtract 18 from both sides.

18−18=2−18

0=−16

Answer:

There aren't any values of x that would make the equation true.

NO SOLUTION

Answer:

P(X > 25) = 0.69

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The sale prices for a particular car are normally distributed with a mean and standard deviation of 26 thousand dollars and 2 thousand dollars, respectively.

This means that [tex]\mu = 26, \sigma = 2[/tex]

Find P(X>25)

This is 1 subtracted by the pvalue of Z when X = 25. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{25 - 26}{2}[/tex]

[tex]Z = -0.5[/tex]

[tex]Z = -0.5[/tex] has a pvalue of 0.31

1 - 0.31 = 0.69.

So

P(X > 25) = 0.69

Step-by-step explanation:

Answer:

The length is 117 ft and the width is 13 ft.

Step-by-step explanation:

From the question itself, we can write down the following equations...

(Let "P" be the perimeter of the rectangle, Let "L" be the length, and let "W" be the width, then...)

L = 9W

and

P = 2L + 2W

Now, we substatute the "L" value and get...

P = 2L + 2W

260 = 2(9W) + 2W

260 = 20W

W = 260 / 20

W = 13

Since we know the width we can now find the length by using the very first formula...

L = 9W

L = 9(13)

L = 117

Therefore, the length is 117 ft and the width is 13 ft.

Answer:

x= -2

y= 12

Step-by-step explanation:

5x + y = 2..................eqn 1

x + y = 10 ..................eqn 2

from eqn 1

5x + y = 2, u substitute by making 'y' the subject

y = 2 - 5x .................eqn 3

put eqn 3 into eqn 2

x + y = 10

x + 2 - 5x = 10

x - 5x = 10 - 2

-4x = 8

x = 8 / -4

x = -2

put x = -2 into eqn 1

5x + y = 2

5(-2) + y = 2

-10 + y = 2

y = 2 + 10

y = 12

Answer:

$3283.2

Step-by-step explanation:

Given data

Principal= $2700

Rate= 4%

Time= 5 years

Required

the final Amount A

The compound interest formula is

A=P(1+r)^t

Substitute

A=2700(1+0.04)^5

A=2700(1.04)^5

A=2700*1.216

A=$3283.2

Hence the balance in the account after 5 years is $3283.2

Given:

Some boxes are fully colored.

Each fully colored ten block represents 1 whole.

The number of colored boxes will be divided into 11 equal part.

To find:

The number of squares need to be colored on each of the 10 blocks.

Step-by-step explanation:

From the given figure, it is clear that,

Number of colored box = 55

The number of colored box will be divided into 11.

[tex]\dfrac{55}{11}=5[/tex]

Therefore, 5 squares need to be colored on each of the 10 blocks.
