Remark
You need a split statement like C or D. A and B would have to be considered if the ages were between 12 and 60. However the discounts apply the other way. Up to 12 and over 60. You need two inequalities to describe this.
<em><u>Under 12</u></em>
x ≤ 12
The pointy end of the arrow points toward the x. x must be less than or at most equal to 12. The pointy end of the inequality must be directed towards the smaller number.
<em><u>Over 60</u></em>
x ≥ 60
This time the pointy end is directed towards the 60. x must be at least 60 and then upwards.
So C is the correct answer.
Answer:
The answer would be 8 cubic inches
Step-by-step explanation:
Answer:
BC = 5
BA11
angle D = 27
Step-by-step explanation:
If the triangles are similar
ABC ≅ DEF
That means AB ≅ DE
BC ≅ EF
and CA ≅ FD
We want to find AB so it is equal to DE
BC = EF = 5
BA = AB = DE =11
We also know the angles are equal
A = D
B = E
C = F
Angle A = angle D = 27
38m².
Answer:
Solution given;
diagonal 1=8+11=19m
diagonal 2=2+2=4m
the area of a kite =½*diagonal 1*diagonal 2
=½*4*19=38m²
<u>The</u><u> </u><u>area</u><u> </u><u>of</u><u> </u><u>kite</u><u> </u><u>is</u><u> </u><u>3</u><u>8</u><u>m²</u><u>.</u>
