My homework asks to evaluate this: 8-11 Times the square root of 25 over 121
navik [9.2K]
8 - 11 = -3. The square root of 25/121 =  (the square root of 25) / (the square root of 121) = 5/11 .   -3 x 5/11 = -3/1 x 5/11 = (-3 x 5) / (1 x 11) = (-15)/11 = -15/11.

Mai has a rectangular poster. The poster is 1.6 meters long and 1.2 meters wide.
dangina [55]

Answer:

19,200 cm^2.

Step-by-step explanation:

The area = 1.2 * 1.6 = 1.92 m^2.

There are 100 cm to 1 meter,  so 1 square meter = 100^2 = 10,000 cm^2.

Therefore 1.92 m^2 = 10,000 * 1.92 =  19,200 cm^2.

50 pts and brainliest for first answer
gavmur [86]

Answer:

An acute angle ("acute" meaning "small") is an angle smaller than a right angle. The range of an acute angle is between 0 and 90 degrees.

An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.

Protractor: an instrument for measuring angles, typically in the form of a flat semicircle marked with degrees along the curved edge.

Degrees: a unit of measurement of angles, one three-hundred-and-sixtieth of the circumference of a circle.

Right Angel: an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.

Straight Angle: an angle of 180°.

Please Help I'm not really good at math
UkoKoshka [18]

The true statements about the triangles RST and DEF are: (a), (d) and (e)

<h3>How to determine the true statements?</h3>

The statement ΔRST ≅ ΔDEF means that the triangles RST and DEF are congruent.

This above implies that:

  • The triangles can be mapped onto each other by rigid transformations such as reflection, translation and rotation
  • The transformation does not include dilation
  • Corresponding sides are congruent

The above means that the possible true statements are: (a), (d) and (e)
