Answer:
6
Step-by-step explanation:
put unknown as y
area of rectangle = width × long
y(y - 2)=48
y² -2y =48
u can use scientific calculator to find this
y²-2y-48=0
(y-8)(y+6)=0
y=8 y=-6
take the positive value and ignore the negative value
width=y-2 long=8
8-2=6
I hope this help you :)
Step-by-step explanation:
tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)
= (sin2B + cos2B)/[(cosB)(sinB)]
= 1/[(cosB)(sinB)]
= (1/cosB)(1/sinB)
= (secB)(cscB)
Answer:
<u><em>They each had </em></u><u><em>1/20 of the original meal</em></u>
Step-by-step explanation:
<u><em>To begin, </em></u><u><em>there are 4 people</em></u><u><em>. Her siblings, and herself. She is </em></u><u><em>splitting the 1/5 leftover</em></u><u><em> to feed them. To do this, we simply </em></u><u><em>take 1/5 and put it into a fraction to get 0.2</em></u><u><em>. Next, we can </em></u><u><em>put 0.2 / 4 into a calculator</em></u><u><em> to get how much each person can get.</em></u>
<u><em>0.2 / 4 = 0.05.</em></u>
<u><em>Now, we need to </em></u><u><em>turn it into a fraction</em></u><u><em> to find out how much they had in fraction form of the original.</em></u>
<u><em>0.05 = 1/20</em></u>
<u><em>They each had </em></u><u><em>1/20 of the original meal</em></u>

Answer:
8x + 16y = 39 and
40x + 8y = 42
Step-by-step explanation:
Let the length of the blue tiles is b inches and that of the white tiles is w inches.
So, given that a row of 8 blue tiles and 16 white tiles has a length of 39 inches and a row of 40 blue tiles and 8 white tiles has a length of 42 inches.
Therefore, we can write the system of linear equations that represents the relationship between the length if a blue tile and a white tile in inches as
8x + 16y = 39 and
40x + 8y = 42 (Answer)
