Answer:

the are is 20

Step-by-step explanation:

1+2+2+2+2+3+3+5=20

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.)

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:

10 times

Step-by-step explanation:

Given that:

Number of sections = (A, B, C, D) = 4

Probability of spinner landing on section B on a single spin = required outcome / Total possible outcomes

P(landing on B) = 1 /4

Predicted Number of times spinner will land on D ; if spinner is spurned 40 times

1/4 * 40 = 10 times

Answer:

$1800

He owes them $900 each

Step-by-step explanation:

Profit = Revenue -  (fixed cost + material cost)

fixed cost $400 x 2 = 800

4900 - (800 + 1400) = $2,700

Since they share the profits equally, each would get 2700/3 = 900

Answer:

Quadrent II

Step-by-step explanation:

It is like a elevator. You have to walk to the elevator to go before you can go up. So you go to the negative area first and then climb up because 8 is positive, and that would land you in Quadrent II

Answer:

4

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:

x = 23 degrees

Step-by-step explanation:

It is given that the two parallel lines, (m) and (n) are intersected by a transversal. The two given angles (5x - 20) and (85) are alternate corresponding. Meaning that they are supplementary; their angle measures add up to (180) degrees. Based on this given information, form an equation and solve for the parameter (x).

(5x - 20) + (85) = 180

Simplify,

5x + 65 = 180

Inverse operations,

5x + 65 = 180

    -65      -65

5x = 115

Answer:

706.3 cm³

Step-by-step explanation:

Given

"The cone and cylinder above have the same radius and height..."

the volume of the cone = 210 cubic centimeters

Formula

The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.

How to solve

Given radius and height calculate the volume, lateral surface area, and total surface area.

Calculate V, L, A | Given r, h

use the formulas above

Given radius and volume calculate the height, lateral surface area, and total surface area.

Calculate h, L, A | Given r, V

h = V / πr2

Given radius and lateral surface area calculate the height, volume, and total surface area.

Calculate h, V, A | Given r, L

h = L/2πr

Given the height and lateral surface area calculate the radius, volume, and total surface area.

Calculate r, V, A | Given h, L

r = L/2πh

Given height and volume calculate the radius, lateral surface area, and total surface area.

Calculate r, L, A | Given h, V

$r = √( V / πh )

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]

Answer:

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.
