Answer:
B) 12
Step-by-step explanation:
Given:
ΔABC ~ ΔDEC
AB ~ DE
AC ~ DC
BC ~ EC
We will just use ratios and substitute DE as x:
[tex]\frac{AB}{AC} =\frac{DE}{DC} \\\\\frac{16}{20} =\frac{x}{15} \\\\20x=240\\\\x=\frac{240}{20} \\\\x=12[/tex]
DE = 12
The measure of the side DE of the triangle DEC will be 12. Then the correct option is B.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. If two triangles are similar, then the ratio of the corresponding sides will remain constant.
The triangles ABC and DEC are similar triangles. Then the ratio of the corresponding sides will be the same.
DE/AB = CD/AC
From the diagram, AB = 16, AC = 20, and CD = 15. Then the measure of the side DE will be given as,
DE/16 = 15/20
DE/16 = 0.75
DE = 16 x 0.75
DE = 12
The measure of the side DE of the triangle DEC will be 12. Then the correct option is B.

Answer:
64
Step-by-step explanation:
Let the missing side be " x "
30 / ( 30 + 10 ) = 48 / x.
30 / 40 = 48 / x
3 / 4 = 48 / x
3 * x = 4 * 48
x = 4 * 48 / 3
= 4 * 16
x = 64
Find the area of this figure to the nearest hundredth. Use 3.14 to approximate pi.
(The figure is a right triangle conjoined to a semi-circle. The semi-circle's diameter is 8, the triangle's base is 6, the triangle's height is 8. )
Answers
Answer:
49.12 square units
Step-by-step explanation:
Area of triangle = [tex]\dfrac{1}{2}*base *height[/tex]
[tex]=\dfrac{1}{2}*6*8=3*8 = 24 \ sq.units[/tex]
Circle:
d = 8 units
r = 8/2 = 4 units
[tex]Area \ of \ semicircle = \dfrac{1}{2}\pi r^{2}\\[/tex]
[tex]=\dfrac{1}{2}*3.14*4*4=3.14*2*4= 25.12 \ sq.units[/tex]
Area of the figure = area of triangle +area of semicircle
= 24 + 25.12
= 49.12 sq. units

Later, he gave four to each of his friends. He only has 4 remaining. How many friends does he have?
Answers
Answer:
He has 19 friends
Step-by-step explanation:
If he won 80 bouncy balls and at the end he is left with four we can subtract 4 from 80 to get 76 and then since we know that he gave 4 to each of his friends we can then divide 76 by 4 to get 19.
