Answer:
c. 47.7 m
Step-by-step explanation:
If you draw a right triangle to represent the problem, the catheti are the vertical distance from the bird's eyes to the field mouse and the separation from the field mouse to the base of the tree. The 50° of depression is measured from the horizontal in clockwise, the angle that summed with the 50° of the depression can be called α. Then:
α+50=90
α=90-50=40°
The trigonometric function than relates te two catheti with the angle α is:
tan(α)=opposite/adjacent
tan40=40/x
x=40/tan40=40/0.8390=47.7m
8 and 10 aren't functions. In a function each input has only one output.
For 8, input 1 = 4, 7
For 10,input 3=7, 6
There are 16 ounces in a pound. If there are 4 pounds, then you take 16 and multiply it by 4 and then add 6.
The answer is: 70.
Nice
4s=amount of grams of protine in straberry for s ounces
3b=amount of grams of protine in banana for b ouces
total ounces is 6
s+b=6
total grams is 22
4s+3b=22
s+b=6
4s+3b=22
those are the 2 equations
a.
s+b=6
4s+3b=22
b. elmination, we can elminate alll the b's and have 1s left
c.
multiply first equaiton by -3 and add to second
4s+3b=22
<u>-3s-3b=-18 +</u>
1s+0b=4
s=4
sub
s+b=6
4+b=6
minus 4
b=2
4 oz straberry
2 oz banana
Assuming that the room is rectangle and carpet is rectangle
area=legnth times width
legnth=longer than width
12 is longer than 8
12ft=legnth
8ft=width
now convert to yards
1 yard=3 feet
1 foot=1/3 yard
12 ft times 1/3=4yards
8 ft times 1/3=8/3yards
multiply
area=4 tiimes 8/3
area=32/3
area=10 and 2/3 square yards
