Answer:

10.2 inches

Step-by-step explanation:

we know that

In this problem we have two cases

First case

The given lengths are two legs of the right triangle

so

[tex]a=12\ in, b=15\ in[/tex]

Applying the Pythagoras Theorem

Find the length of the hypotenuse

[tex]c^{2}=a^{2} +b^{2}[/tex]

substitute

[tex]c^{2}=12^{2} +15^{2}[/tex]

[tex]c^{2}=369[/tex]

[tex]c=19.2\ in[/tex]

Second case

The given lengths are one leg and the hypotenuse

so

[tex]a=12\ in, c=15\ in[/tex]

Applying the Pythagoras Theorem

Find the length of the other leg

[tex]b^{2}=c^{2} - a^{2}[/tex]

substitute

[tex]b^{2}=15^{2} - 12^{2}[/tex]

[tex]b^{2}=81[/tex]

[tex]b=9\ in[/tex]

Find the difference between the two possible lengths of the third side of the triangle

Answer:  The length of the indicated segment is 14.45 units.

Step-by-step explanation:  We are given to find the length of the indicated segment.

From the figure, we note that

A chord is bisected by the radius of the circle that makes a right-angled triangle with hypotenuse measuring 16.1 units and the other two sides measures x units and 7.1 units.

Using Pythagoras theorem, we get

[tex]x^2+7.1^2=16.1^2\\\\\Rightarrow x^2+50.41=259.21\\\\\Rightarrow x^2=259.21-50.41\\\\\Rightarrow x^2=208.8\\\\\Rightarrow x=\pm\sqrt{208.8}\\\\\Rightarrow x=\pm14.45.[/tex]

Since x is the length of side of a triangle, so we get

x = 14.45.

Thus, the length of the indicated segment is 14.45 units.

Fractional division is fractional multiplication with the second fraction the reciprocal of itself. This means the problem can be written as [tex]\frac{7}{9}*\frac{9}{4}[/tex]. Fractional multiplication results in the multiplication of the numerators and denominators---in this case, [tex]\frac{7}{4}=1\frac{3}{4}[/tex]

Answer:

Option B) a = 1, b = 3, c = 4  

Step-by-step explanation:

We are given the following information in the question:

We are given an expression:

[tex]\displaystyle\frac{7}{9} \div \frac{4}{9} = a\frac{b}{c}[/tex]

The solving of the above expression can be done in the following manner:

[tex]\displaystyle\frac{7}{9} \div \frac{4}{9}\\\\\frac{7}{9}\times \frac{9}{4}\\\\\frac{7}{4} =\frac{(4\times 1) + 3}{4}= 1\frac{3}{4}[/tex]

Comparing the right side of the expression, we have,

[tex]a\displaystyle\frac{b}{c} = 1\frac{3}{4}[/tex]

Comparing, we get,

a = 1, b = 3, c = 4

Option B) s the correct option.

Answer:

Step-by-step explanation:

1/2x-3/4=3/8-5/8

Combine like terms on the right hand side

1/2x-3/4=-2/8

Simplify the fraction

1/2x-3/4=-1/4

Add 3/4 to each side

1/2x-3/4+3/4 = -1/4+3/4

1/2x = 2/4

Multiply each side by 2

1/2x *2 = 2/4*2

x = 4/4

Step-by-step explanation:

When it is 6:00 hours in Honolulu, it is 15:00 hours in London, this means that there are 15 - 6 = 9 hours of difference.

Paul got into London at 12:00 p.m, that is, at 12 - 9 = 3:00 p.m. Friday Honolulu time. Paul’s flight left Honolulu at 2:00 p.m. Thursday, so he spent 25 hours flighting.

When the flight started, the temperature in London was 30 °C, after 25 hours the temperature dropped 25 °C, so it was 30 - 25 = 5 °C.

To convert from °C to °F, we use the following formula:

(x °C × 9/5) + 32 = y °F

Replacing with x = 5

(5 °C × 9/5) + 32 = 41 °F

Answer:

14 weeks

Step-by-step explanation:

t = 25 + 8.25w

Len  needs 135.75

135.75 =  25 + 8.25w

Subtract 25 from each side

135.75-25 = 25-25 + 8.25w

110.75 = 8.25w

Divide each side by 8.25

110.75/8.25 = 8.25w/8.25

13.42424 = w

Since we need at least 135.75, it will take Len a little more than 13 weeks, so it will take Len 14 weeks to have enough money

Answer:

14 weeks

Step-by-step explanation:

It will take 14 weeks for Len to save enough money to buy a television.

t = 25 + 8.25w

135.75 =  25 + 8.25w

Answer:

The line containing the midpoints of two sides of a triangle is parallel to the third side ⇒ proved down

Step-by-step explanation:

* Lets revise the rules of the midpoint and the slope to prove the

  problem

- The slope of a line whose endpoints are (x1 , y1) and (x2 , y2) is

  [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

- The mid-point of a line whose endpoints are (x1 , y1) and (x2 , y2) is

  [tex](\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})[/tex]

* Lets solve the problem

- PQR is a triangle of vertices P (0 , 0) , Q (2a , 0) , R (2b , 2c)

- Lets find the mid-poits of PQ called A

∵ Point P is (x1 , y1) and point Q is (x2 , y2)

∴ x1 = 0 , x2 = 2a and y1 = 0 , y2 = 0

∵ A is the mid-point of PQ

∴ [tex]A=(\frac{0+2a}{2},\frac{0+0}{2})=(\frac{2a}{2},\frac{0}{2})=(a,0)[/tex]

- Lets find the mid-poits of PR which called B

∵ Point P is (x1 , y1) and point R is (x2 , y2)

∴ x1 = 0 , x2 = 2b and y1 = 0 , y2 = 2c

∵ B is the mid-point of PR

∴ [tex]B=(\frac{0+2b}{2},\frac{0+2c}{2})=(\frac{2b}{2},\frac{2c}{2})=(b,c)[/tex]

- The parallel line have equal slopes, so lets find the slopes of AB and

  QR to prove that they have same slopes then they are parallel

# Slope of AB

∵ Point A is (x1 , y1) and point B is (x2 , y2)

∵ Point A = (a , 0) and point B = (b , c)

∴ x1 = a , x2 = b and y1 = 0 and y2 = c

∴ The slope of AB is [tex]m=\frac{c-0}{b-a}=\frac{c}{b-a}[/tex]

# Slope of QR

∵ Point Q is (x1 , y1) and point R is (x2 , y2)

∵ Point Q = (2a , 0) and point R = (2b , 2c)

∴ x1 = 2a , x2 = 2b and y1 = 0 and y2 = 2c

∴ The slope of AB is [tex]m=\frac{2c-0}{2b-2a}=\frac{2c}{2(b-c)}=\frac{c}{b-a}[/tex]

∵ The slopes of AB and QR are equal

∴ AB // QR

∵ AB is the line containing the midpoints of PQ and PR of Δ PQR

∵ QR is the third side of the triangle

∴ The line containing the midpoints of two sides of a triangle is parallel

  to the third side

Answer:

$1050

Step-by-step explanation:

To solve, multiply your two expenses against your $6000 and find the difference.

The man spends 1/5 of his salary on children's education.

To find how much he spends on his children's education in dollars, multiply 1/5 against $6000.

[tex]\frac{1}{5} *6000\\1200[/tex]

The man spends $1200 on children's education.

The man spends 5/8 of his salary on his aged mother and unemployed sister.

Repeat the same process as the first step, this time multiplying 5/8 against $6000.

[tex]\frac{5}{8} *6000\\3750[/tex]

The man spends $3750 on his aged mother and unemployed sister.

Add these two expenses together.

[tex]1200+3750\\4950[/tex]

The man has combined expenses of $4950.

To find how much money he has left, subtract his expenses from his $6000 income.

[tex]6000-4950\\1050[/tex]

The man has $1050 remaining.

Answer:

- cos 25°

Step-by-step explanation:

Cosine function is one of the trigonometric functions. Cosine function is regarded as an even function, which means that f(-x) = f(x). Also, cosine function is positive in the first quadrant and the last quadrant and negative in the second quadrant and the third quadrant. 155° lies in the second quadrant since 155° is smaller than 180°. Therefore, the basic angle or the reference angle of 155° is 180° - 155° = 25°. We know that cos 155° will be negative because it lies in the second quadrant and cos 25° will be positive because it lies in the first quadrant. Since cos 55° is positive, and cos (-25°) = cos 25° by the even function property, therefore option 2 and option 3 are incorrect since cos 155° is negative. Therefore, option 1 is the correct answer i.e. cos 155° = - cos 25°!!!

P(4, - 1 )

Step-by-step explanation:

The ratio 1 : 1 represents the midpoint of segment AB

Using the midpoint formula

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

with (x₁, y₁ ) = (13, 1) and (x₂, y₂ ) = (- 5, - 3), so

P = [0.5(13 - 5), 0.5(1 - 3) ] = [0.5(8), 0.5(- 2) ] = (4, - 1 )

the midpoint P has the coordinates (4, −1).

To find the coordinates of point P that partitions segment AB in a 1:1 ratio, also known as the midpoint, we use the midpoint formula. Given the coordinates A(13,1) and B(−5,−3), the midpoint formula is ((x1 + x2)/2, (y1 + y2)/2).

Applying the values from A and B:

Therefore, the midpoint P has the coordinates (4, −1).

Answer:

5 hours

Step-by-step explanation:

The total amount of the repair is $265 and includes parts and an hourly rate. We are told the parts are $90. Subtract the price of the parts, $90, from the total of $265.

$265 - $90 = $175

The $175 is only due to the hourly rate.

Now we divide the total due to the hours by the hourly rate to find the number of hours.

175/35 = 5

The equation of the line is y = 0.6*x - 1, the graph is in the image at the end.

How to find the linear equation?

A linear equation in the slope-intercept form can be written as:

y = ax + b

Where a is the slope and b is the y-intercept.

If a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is given by:

a = (y₂ - y₁)/(x₂ - x₁)

Here we have the points (−5,−4) and (5,2), so the slope is:

a = (2 + 4)/(5 + 5) = 6/10 = 0.6

y = 0.6*x + b

And it passes through (5, 2), then:

2 = 0.6*5 + b

2 - 0.6*5 = b

-1 = b

The equation is:

y = 0.6*x - 1

The graph is in the image below.
