Answer:

19.8 m

Step-by-step explanation:

To find the height of the tree, we can use the trig ratio tangent:

θ = angle, h = height

tan θ [tex]= \frac{opposite}{adjacent}[/tex]

tan 33° = h / 30.5

h = (tan 33°)(30.5)

h = (0.6494)(30.5)

h = 19.8 m

Given:

In a right angle triangle ABC, altitude BD drawn to hypotenuse AC.

AD=3 and, AC=27.

To find:

The length of AB.

Solution:

Draw a figure by using the given information as shown below.

In triangle ABC and ADB,

[tex]\angle ABC\cong \angle ADB[/tex]              (Right angles)

[tex]\angle BAC\cong \angle DAB[/tex]              (Common angle)

[tex]\triangle ABC\sim \triangle ADB[/tex]              (AA similarity postulate)

We know that the corresponding parts of congruent triangles are proportional. So,

[tex]\dfrac{AC}{AB}=\dfrac{AB}{AD}[/tex]

After substituting the given values, we get

[tex]\dfrac{27}{AB}=\dfrac{AB}{3}[/tex]

[tex]27\times 3=AB\times AB[/tex]

[tex]81=AB^2[/tex]

Taking square root on both sides, we get

[tex]\sqrt{81}=AB[/tex]

[tex]9=AB[/tex]

Therefore, the length of AB is 9 units.

Answer:

53,901

Step-by-step explanation:

Here is the complete question :

In which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?

43,567

45,248

53,901

562,011

In the number 245,093 :

3 = units

9 = tens

0 = hundred

5 = thousand

4 = ten thousand

2 = hundred thousand

the value of 5 in the number is 5000. the number that would have a value that it 10 times greater than 5 in 245,093 must occupy the value  of ten thousand.

looking through the options, it is only in 53,901 that 5 occupies a value of ten thousand

Answer:

The angles are 78° and 102°.

Step-by-step explanation:

Let the one angle is y and the other number if y + 24.

The sum of the angles of the linear pair is 180°.

So, according to the question

y + y + 24 = 180

2 y = 180 - 24

2 y = 156

y = 78°

So, one angle is 78° and the other is 78° + 24° = 102°.

Answer:

His time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.

Step-by-step explanation:

With an standard deviation of 3.2 minutes, it is clear that the maximum time taken by Roman to complete his run of 3 miles would be

Average time + standard deviation = 24.7 minutes + 3.2 minutes = 27.9 minutes

The minimum time taken by Roman to complete his run of 3 miles would be

Average time - standard deviation = 24.7 minutes  - 3.2 minutes = 21.5 minutes

Hence, his time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.

Answer:

7.6 inches

Step-by-step explanation:

We solve the above question using the Law of Cosines.

The formula is given as:

h² = i² + j² - 2ij Cos H

h = √i² + j² - 2ij Cos H

From the above question:

i = 6.6 inches

j = 6.4 inches

Length h = ?

Angle H=62º.

Hence:

h= √6.6² + 6.4² - 2 × 6.6 × 64 × Cos 62

h = √43.56 + 40.96 - 84.48 × Cos 62

h = 7.64292 inches

Approximately to the nearest tenth, Length h = 7.6 inches

Answer:

[tex]y=-5x+2[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that the line passes through are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (1,-3) and (-3,17)

[tex]=\frac{17-(-3)}{-3-1}\\=\frac{17+3}{-3-1}\\=\frac{20}{-4}\\=-5[/tex]

Therefore the slope of the line is -5. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-5x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-5x+b[/tex]

Plug in one of the given points and solve for b

[tex]-3=-5(1)+b\\-3=-5+b[/tex]

Add 5 to both sides of the equation to isolate b

[tex]-3+5=-5+b+5\\2=b[/tex]

Therefore, the y-intercept of the equation is 2. Plug this back into [tex]y=-5x+b[/tex]:

[tex]y=-5x+2[/tex]

Answer:

Step-by-step explanation:

cos x cos (3x)+sinx sin (3x)=0

cos (x-3x)=0

cos(-2x)=0

cos 2x=0=cos (2n+1)π/2

where n=0,1,2,3∞∞∞∞

2x=(2n+1)π/2

x=(2n+1)π/4

put n=0,1,2,3

x=π/4,3π/4,5π/4,7π/4

The solution of equation cos(x) cox(3x) + sin(x) sin(3x) = 0 are [tex]\bold{x=\frac{\pi}{4},~\frac{3\pi}{4}}[/tex]

It is a mathematical statement which consists of equal symbol between two algebraic expressions."

cos(A - B) = cos(A)cos(B) + sin(A)sin(B)

For given question,

We have been given an equation cos x cox(3x)+sin x sin(3x)=0 .............(i)

We know, cos(A - B) = cos(A)cos(B) + sin(A)sin(B)

So, cos x cox(3x) + sin x sin(3x) = cos(x - 3x)

So, the equation (i) becomes,

⇒ cos(x - 3x) = 0

⇒ cos(-2x) = 0                      ..................(ii)

We know, for any angle m,

cos(-m) = cos(m)

⇒ cos(-2x) = cos(2x)

So the equation (ii) would be,

cos(2x) = 0

We know, in the interval [0, 2π]

cos([tex]\frac{\pi}{2}[/tex]) = 0 and cos([tex]\frac{3\pi}{2}[/tex]) = 0

This means, [tex]2x=\frac{\pi}{2}[/tex]      or    [tex]2x=\frac{3\pi}{2}[/tex]

⇒ [tex]x = \frac{\pi}{4}[/tex]      or    [tex]x=\frac{3\pi}{4}[/tex]

Therefore, the solution of equation cos(x) cox(3x)+sin(x) sin(3x)=0 are [tex]\bold{x=\frac{\pi}{4},~\frac{3\pi}{4}}[/tex]

c = √500

Step-by-step explanation:

a rectangle has four inner angles equals to 90 degrees

so for find c we can use the Pythagorean theorem because it is an hypotenuse of a right triangle

c^2 = 10^2 + 20^2

c^2 = 100 + 400

c^2 = 500

c = √500

Answer:

y=3/5x+1

Step-by-step explanation:

Hi there!

We are given the equation -3x+5y=-8 and we want to find the equation of the line that is parallel to -3x+5y=-8 and contains the point (-15,-8)

parallel lines have the same slopes, but different y intercepts.

So let's first find the slope of -3x+5y=-8

We can do this by converting the equation from standard form (ax+by=c where a, b, and c are free coefficients (numbers)) to slope-intercept form (y=mx+b, where m is the slope and b is the y intercept)

add 3x to both sides

5y=3x-8

divide by 5 on both sides

y=3/5x-8/5

3/5 is in the place of where m is, so that means that 3/5 is the slope of the line

we can write the equation of the new line in slope-intercept form.

Here it is so far:

y=3/5x+b

we need to find b

Because the line will pass through the point (-15,-8), we can use it to solve for b

substitute -15 as x and -8 as y

-8=3/5(-15)+b

multiply

-8=-9+b

add 9 to both sides

1=b

substitute 1 as b into the equation

y=3/5x+1

There's the equation of the line :)

Answer:

80% increase

Step-by-step explanation:

First, divide $0.25/$0.45, you get 0.8, turn it into a percent. 0.8=80%

There is an 80% increase.

Check work:

0.25x1.8=0.45

We multiply by 1.8 because 80% increase means 100% (itself) multiplied by 80% of itself, which gives us 180% or 1.8.

0.25x1.8=0.45 ✔️

Answer:

100

Step-by-step explanation:

A dice has 6 sides and, theoretically, each side has the same probability of being rolled. So, if a dice was rolled a number of times, it would land on each side the same number of times. This means that 6 would be rolled 1/6 of the time. Since 1/6 of 600 is 100, that is how many times 6 would be rolled.
