Answer:
v=6
Step-by-step explanation:
2v is positive so keep it
then 2v=12
v=6
Answer:
x=4+√23 , 4-√23
Step-by-step explanation:
x^2-4x=4x+7
x^2-8x-7=0
now solving from quadratic equation
x=4+√23 , 4-√23
Answer:
see the explanation
Step-by-step explanation:
we know that
In a Rhombus opposite angles are congruent and consecutive angles are supplementary
The diagonals are perpendicular and bisect the angles
so
step 1
Find the measure of angle 4
we know that
--->by the diagonals bisect the angles
step 2
Find the measure of angle 1
we know that
----> by opposite angles are congruent
step 3
Find the measure of angle 2
we know that
----> by the diagonals bisect the angles
so
step 4
Find the measure of angle 3
we know that
----> by the diagonals are perpendicular
step 5
Find the measure of angle 5
we know that
----> by complementary angles
step 6
Find the measure of angle 6
we know that
----> by the diagonals bisect the angles
Given that total number of principal dancers = 22
We have to find about how many dancers are in the apprentice company.
So let number of dancers in the apprentice company = x
Then half of the dancers in the apprentice company means x/2
Question says that "A ballet company uses all 22 of its principal dancers, plus 1/2 of its apprentice company in a large production" so that means there are 22+x/2 dancers.
Given that there are total 26 dancers so that means we get equation:
22+x/2=26
x/2=26-22
x/2=4
x=4*2
x=8
Hence final answer is that there are total 8 dancers in the apprentice company.
Answer:
The iron will need 10 amps
Step-by-step explanation:
The extension cord can support uptown 8 amps.
The iron has a 1200watts labelled on it
Converting watts to amps by dividing by 120 gives:
1200watts/120 =10 amps
The iron is 10amps
