Find the missing side lengths using your notes on the 45-45-90 and 30-60-90 special triangles.

Answer:

25

Step-by-step explanation:

Since they were born on consecutive years, their ages are 4 consecutive whole numbers. Let the lowest age be x. Then the other ages are x + 1, x + 2, and x + 3.

Now we add the 4 expressions and set the sum equal to 94.

x + x + 1 + x + 2 + x + 3 = 94

4x + 6 = 94

4x = 88

x = 22

The youngest one is 22.

The oldest one is

x + 3 = 22 + 3 = 25

Answer:

Step-by-step explanation:

Answer:

'Percent (%)' means 'out of one hundred':

0.83% = 0.83 'out of one hundred',

p% is read p 'percent',

0.83% = 0.83/100 = 0.83 ÷ 100

Calculate percentage:

'Percentage' is obtained by multiplying 2,200 by 0.83%

0.83% × 2,200 =

(0.83 ÷ 100) × 2,200 =

(0.83 × 2,200) ÷ 100 =

1,826 ÷ 100 =

18.26

Answer:

The size of the scale model is 60 centimeters.

Step-by-step explanation:

Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:

1m = 100cm

10.8 m = (10.8 x 100) = 1080 cm

1080/18 = X

60 = X

Therefore, the size of the scale model is 60 centimeters.

Step-by-step explanation:

Answer:

b = 8

Step-by-step explanation:

Using Pythagorean Theorem, a[tex]a^{2} +b^{2} =c^{2}[/tex], we just plug in what we know.

We know that the hypotenuse, c, is 10 km. We also know that one of the other side lengths is 6 km, we can plug that into either a or b.

Now, our equation will be: [tex]6^{2} +b^{2} =10^{2}[/tex].

You could also use the equation: [tex]b^{2} =10^{2} -6^{2}[/tex].

Next, we'll just solve the equation.

[tex]10^{2} =100[/tex], [tex]6^{2} = 36[/tex]

[tex]b^{2} =100 - 36[/tex]

[tex]b^{2} = 64[/tex]

[tex]\sqrt{b^{2} } = \sqrt{64}[/tex]

b = 8

Good luck :D

Answer:

Angle WTS will be 180 degree minus 15x. You can write this as an expression:

180-15x

Now you have an expression for each angle in the triangle. Triangles will always have 180 degrees in them. You can add the expressions together and set it equal to 180. Then you can solve the equation for the x variable.

Step-by-step explanation:

Angle SWT + angle WTS + angle TSW = 180 degrees

Replace each angle with the expression then solve.

Answer:

x=7.90 x≈8

Step-by-step explanation:

they are alternate interior angles

so: 7x+6+15x=180

22x+6=180

22x=174

=7.9090......

you can double check my work

Answer:

C=120 degrees

Step-by-step explanation:

We can use the law of cosines to find an angle when we have all three sides

(7)^2 = (5)^2 + (3)^2 -(2)(5)(3)Cos(C)

49 = 25 +9 -30Cos(c)

49= 34 -30Cos(c)

15 = -30Cos(c)

Cos(c) = -1/2

C=120 degrees

Answer:

y = -7x -7

Step-by-step explanation:

If (-1, 0) and (-2, -9) are on the same line then that means their slope is the same. We can find slope with (y1 - y2)/(x1 - x2)

(-2 - (-9)) / (-1 - 0) = 7 / -1 = -7

then we can use the formula y = mx + b

we know that forthe first instance y = 0 and x = -1 and m(slope) = -7

0 = -7*-1 + b

0 = 7 + b

b = -7

our formula then becomes y = -7x -7

Step-by-step explanation:

Answer:

v = 6

Step-by-step explanation:

Given

3(3v-5) = 39

So,

3v - 5 = 39 / 3

=> 3v - 5 = 13

=> 3v = 13 + 5

=> 3v = 18

=> v = 18 / 3

=> v = 6

#HopeItHelps

Answer:

V=6

Step-by-step explanation:

Hope this helped! :)

Simplifying

3(3v + -5) = 39

Reorder the terms:

3(-5 + 3v) = 39

(-5 * 3 + 3v * 3) = 39

(-15 + 9v) = 39

Solving

-15 + 9v = 39

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.

Add '15' to each side of the equation.

-15 + 15 + 9v = 39 + 15

Combine like terms: -15 + 15 = 0

0 + 9v = 39 + 15

9v = 39 + 15

Combine like terms: 39 + 15 = 54

9v = 54

Divide each side by '9'.

v = 6

Simplifying

v = 6

Answer:

3(x - 10)

Step-by-step explanation:

3x - 30 = 3(x - 10)

Hii!

__________________________________________________________

Answer:

3(x-10)

Step-by-step explanation:

Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.

The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain

x-10

Put parentheses around x-10

(x-10)

Next, put 3 outside the parentheses

3(x-10)
