i need help plz i struggling

Answer:

1. 53

2. 20

3. 37

4. 29

Step-by-step explanation:

Since your trying to find the hypotenuse you equation is...

1. 28^2 + 45^2 = C^2

    784 + 2025 = C^2

      Square Root 2809= C^2

    C=53

So after you square root 2809 you get 53.

2. 12^2 + 16^2 = C^2

     144 + 256 = C^2

      Square Root 400 = C^2

    C=20

So after you square root 400 you get 40.

3.  12^2 + 35^2 = C^2

    144 + 1225 = C^2

    Square Root 1369 = C^2

   C=37

So after you square root 1359 you get 37.

4. 20^2 + 21^2 = C^2

   400 + 441 = C^2

  Square root 841 = C^2

  C=20

So after you square root 841 you get 29.

Answer:

Distance between points m and p = 12.53 unit (Approx.)

Step-by-step explanation:

Given:

Co-ordinate of points

m(-10, 3)

p(-4, -8)

Find:

Distance between points m and p

Computation:

Distance between two points = √(x1 - x2)² + (y1 - y2)²

Distance between points m and p = √(-10 + 4)² + (3 + 8)²

Distance between points m and p = √(-6)² + (11)²

Distance between points m and p = √36 + 121

Distance between points m and p = √157

Distance between points m and p = 12.53 unit (Approx.)

Step-by-step explanation:

(-1,4) (1,4) 2,0

The endpoint of the line segment will be (-1, 4) and (2, 0). Then the correct options are B and E.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.

Section Stomach muscle has endpoints A(- 2, 8) and B(4,0). The section is widened at the beginning by a scale variable of 0.5 to make a fragment of the Stomach muscle.

The endpoint of the line segment is given as,

A = 0.5(-2, 8)

A = (-1, 4)

B = 0.5(4, 0)

B = (2, 0)

The endpoint of the line fragment will be (- 1, 4) and (2, 0). Then the right choices are B and E.

More about the dilation link is given below.

Step-by-step explanation:

here's your solution

=> perpendicular^2 = hypotenuse^2 - base^2

=> p^2 = 5^2 - 3^2

=> p^2 = 25 - 9

=> p^2 = 16

=> p = √16

=> p = 4

Answer:

42. x = 25

43. LM = 11

Step-by-step explanation:

For 42, the three angles of a triangle, when added, = 180 degrees. We know that one of the angles is 90 degrees...a right angle.

So: 90 + 2x + x + 15 = 180

105 + 3x = 180

3x = 75

x = 25

If they ask for more information: the three angles are 90 degrees, 50 degrees (2x), and 40 (x + 15). 90 + 50 + 40 = 180

For 43, ray PN bisects (cuts in equal halves) the triangle. We know this because the two segments LP and PM are equal. As a result, the triangles LPM and PNM are mirror images. Since MN = 11, LM also = 11.

Answer:

[tex]P(x < 7) = 0.383[/tex]

Step-by-step explanation:

Given

See attachment for plot

Required

Determine the probability that few than 7 boxes will be needed.

This is represented as:

[tex]P(x < 7)[/tex]

And the solution is:

[tex]P(x < 7) = P(x = 4) + P(x = 5) + P(x = 6)[/tex]

Each probability is calculated by dividing the number of dots by the total dots.

So, we have:

[tex]P(x < 7) = \frac{n(x = 4) + n(x = 5) + n(x = 6)}{Total}[/tex]

From the attached, the formula becomes:

[tex]P(x < 7) = \frac{4 + 6 + 3}{4+6+3+4+4+6+3+2+1+2+0+1}[/tex]

[tex]P(x < 7) = \frac{13}{36}[/tex]

[tex]P(x < 7) = 0.361[/tex]
