Step-by-step explanation:

Let me know if you need the work

The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]

Let the sides of Juan's triangle be x, y and z. So:

[tex]x = 5 \\ y = 8\\ z = 12[/tex]

The perimeter (J) of Juan's triangle is calculated by adding all sides.

So:

[tex]J =x +y +z[/tex]

This gives:

[tex]J =5 + 8 + 12[/tex]

[tex]J =25[/tex]

From the question, we understand that:

The perimeter (S) of Stephanie's triangle is half that of Juan.

This means that:

[tex]S = \frac 12J[/tex]

Substitute 25 for J

[tex]S = \frac 12 \times 25[/tex]

Hence, the numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]

Answer:

1/32

Step-by-step explanation:

First you must multiply the 3 and the -5 because the -5 is out of the parenthases. then you will get 2^-15. You cannot have a negative exponent so you chance it to 1/2^15. Then simplify to get the answer

Answer:

[tex]if \: b \: is \: the \: mid \: point \: then \: \\ ab = bc \\ then \: 6x - 6 = 72 \\ 6x = 72 + 6 \\ 6x = 78 \\ x = \frac{78}{6} \\ x = 13 \\ thank \: you[/tex]

This question is simply about division of line segments.

x = 13

AB = AC

Thus, 6x - 6 = 72

Add 6 to both sides to get;

6x = 78

divide both sides by 6 to get;

x = 13

Answer:

∠ B ≈ 64.62°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosB = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{3}{7}[/tex] , then

∠ B = [tex]cos^{-1}[/tex] ([tex]\frac{3}{7}[/tex] ) ≈ 64.62° ( to the nearest hundredth )

Step-by-step explanation:

The straight line from the starting point forms a hypotenuse of the right triangle with the legs 75 and 65 miles. Use Pythagorean.

The distance is:

Using Pythagorean theorem

[tex]\\ \rm\longmapsto H^2=P^2+B^2[/tex]

[tex]\\ \rm\longmapsto H^2=75^2+65^2[/tex]

[tex]\\ \rm\longmapsto H^2=9850[/tex]

Answer:

10+15i/13

Step-by-step explanation:

This question is about complex numbers.

so,

in this type of questions we have to multiply this fraction by the conjugate of the denominator

   conjugate of the denominator is  3-2i

    1)    5i(3-2i)/(3+2i)(3-2i)

    2) 15i-10i^2/9-4i^2   ( we know that i^2 = -1 )

    3) 15i+10/9+4

     4) 15i+10  / 13

Answer:

7/8

Step-by-step explanation:

1/4 + 5/8 = 2/8 + 5/8 = 7/8

= amount used for pepper and tomatoes

2 1/2 - 3/4 = 5/2-3/4 = 10/4 -3/4 = 7/4

= total amount used

so

7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce

Answer:

–3x + y =1

y= 1 +3x

4x + y =8 —> 4x + ( 1 + 3x ) = 8

7x + 1 = 8 —> 7x = 8 – 1 —> 7x = 7

x = 7/7 —> x = 1

y= 1 + 3x —> y = 1 + 3 (1) —> y = 1+ 3

y= 4

(x , y ) —> ( 1 , 4 )
