Answer:
Step-by-step explanation:
Given:
Top and bottom has fourth root. so we take fourth root in common
When we divide 810 by 2. we will get 405
Now we simplify the fourth root
405 can be written as 3*3*3*3*5
Eighteen and
fifty-two thousandths

Step-by-step explanation:
(16)
The mid segment ZW is half the sum of the parallel bases
ZW = = = 29
(17)
The lower base angles are congruent , so
∠ UYX = ∠ VXY = 35°
(18)
Any lower base angle is supplementary to any upper base angle , then
∠ VUY = 180° - ∠ UYX = 180° - 35° = 145°
(19)
= ZW
= 10 ( multiply both sides by 2 to clear the fraction )
10x = 20 ( divide both sides by 10 )
x = 2
Then
XY = 7x + 1 = 7(2) + 1 = 14 + 1 = 15
(20)
The legs are congruent , so
UY = VX
5a - 6 = 3a + 2 ( subtract 3a from both sides )
2a - 6 = 2 ( add 6 to both sides )
2a = 8 ( divide both sides by 2 )
a = 4
Answer:
Step-by-step explanation:
3 3/4 ÷ 7/12
= 15/4 ÷ 7/12
= 15/4 x 12/7
= 6 3/7 rounds <=== so 6 complete rounds
