Step-by-step explanation:
In order to get from 8 to 56, we have to multiply by 7.
We always do the same to the top! 3 multiplied by 7 = 21.
In order to get from 7 to 56, we have to multiply by 8.
We always do the same to the top! 3 multiplied by 8 = 24.
D i believe if x=1 & 1/2 and y=1 then 2-1/2*1 would equal 1 1/2 which then the equation would be complete and correct. i tested and y=2 or y=3 would both still be correct.
Answer:
SUM OF ALL ANGLES OF A TRIANGLE =180
THEREFORE,
X+8+2X-3+6X-5=180
9X=180
X=20.
THEREFORE,<J=X+8=20+8=28
<K=6X-5=6*20-5=120-5=115
<L=2X-3=2*20-3=40-3=37.
Answer:
(A) 2 meter
Step-by-step explanation:
It is given that the ladder forms a 72º angle with the ground and rests against the house at a spot that is 6 meters high.
Let the measure of bottom of the ladder from the wall be x, then using the trigonometry, we have
≈
Thus, option A is correct.
Answer:
$7200 in the fund rose 6% n $2800 in the fund rose 9%
Step-by-step explanation:
let x be the amount in the fund rose 6%
gain in one year=x*6%=0.06x
total amount is 10000
so amount in the fund rose 9% = 10000-x
gain in one year=(10000-x)*9%=900-0.09x
total gain=0.06x+900-0.09x=900-0.03x
=684
900-684=0.03x
0.03x=216
x=7200
the other fund amount=10000-7200=2800
