Let M be the age of Maggie and B the age of her younger Brother:

Rewrite the problem from English language to Math's:
 B = 2.M - 10 (1)
and  M + B = 29 (Given) OR    B  =  29 -M (2)
Plug 2) into 1):

29 -M = 2.M -10
 29 + 10 = 3 M →→3M = 39 and M = 39/3 = 13
Replace M by 13 and you will find B =6

Then Maggie = 13 year old and her brother B = 6 year old

The formula for wind chill (in degrees Fahrenheit) is given byC = 35.74 + 0.6215T ? 35.75v0.16 + 0.4275Tv0.16 where is the wind
PIT_PIT [208]

Answer:

dC =0.6899T + 30.02

dC/C = (0.6899T + 30.02)/(35.74 + 0.6215T - 35.75V^0.16 + 0.4275Tv^0.16

Step-by-step explanation:

C= 35.74 + 0.6215T - 35.75v^0.16 + 0.4275Tv^0.16

dC = 35.74 + 0.6215T - (35.75×0.16) +:(0.4275×0.16)

dC = 35.74 + 0.6215T - 5.72 + 0.684T

dC = 0.6899T + 30.02

dC/C = (0.6899 + 30.02)/(35.74 + 0.6215T - 35.75Tv^0.16 + 0.4275Tv^0.16

Triangle A'B'C' is a rotation of triangle ABC by 60 degrees using Q as the center.
deff fn [24]

9514 1404 393

Answer:

  see below

Step-by-step explanation:

When a figure is rotated about a center point, the central angle formed by any point on the figure and the corresponding image point will be the rotation angle. Every image point is the same distance from the center of rotation that the pre-image point was. No lengths or angles are changed: rotation is a "rigid motion", so the rotated figure is congruent with the original.

__

-Angle AQA' is 60 degrees.

-Triangles ABC and A'B'C' are congruent.

-Angle ABC is congruent to angle A'B'C'. (<em>this is one of the angles of the congruent triangles</em>)

-Segment BC is congruent to segment B'C'

-Segment AQ is congruent to segment A'Q.
