5/4 would be your answer.
Answer:B
Step-by-step explanation: 113,000 - 71,500 = 41,500
Answer:
Regular dance exercise improves the endurance of body muscles, allowing them to work harder for longer periods of time without feeling tired. Dancing also raises the body's heart rate to heighten stamina. You'll be jumping out of bed each morning in no time.
Step-by-step explanation:
Answer:
The width is 10 and the length is 14.
Step-by-step explanation:
To draw this conclusion, first use the equation<em> A = lw = 140
.</em>
Remember the length is six less than twice the width, in other words, the length equals 2 time the width minus 6:<em> l = 2w - 6
</em>
Now you want to substitute numbers in:
140 = (2w - 6)(w)
140 = 2w^2 - 6w
2w^2 - 6w -140 = 0
w^2 - 3w - 70 = 0
Factorable by inspection!
(w - 10)(w + 7) = 0
w = 10
<em>w = -7 (nonsense - ignore)
</em>
I = 14
Answer:
55 deg 30 Minutes = 55.5 degrees
sin = opp/hyp
sin(55.5) = altitude/10
Altitude = 10*sin(55.5)
Altitude = 10 * sin(55.5) = 8.241261886
Rounded to nearest 10th
Altitude = 8.2 cm
b. for base use Low of Cosines
Let C = base
Side A and B = length 10 Cm
c^2 = 2*a^2 -2a^2*cos(<C)
<C = 180 - 2*55.5 = 180 -111 = 69 degrees
c = sqrt ( 2a^2 - 2a^2*cos(<C)
c = sqrt ( 2*100- 200*cos(69))
c = sqrt (200 - 200*cos(69) ) = 11.32812474
Answer base
c = 11.3 cms
c.
Area = (1/2)*b * h
Area = (1/2)*(answer a * answer b)
Area = (1/2)* 11.32812474* 8.241261886 = 46.67902132
Area = 46.7 (rounded)
Area = ( 1/2) * a*b*sin(<C) = (1/2)*10*10*sin(69) =
Area = 50* sin(69) = 46.67902132
Area = 46.7 (rounded)
