Oranges=r
apples=a
12<em>r</em>+7<em>a</em>=5.36
-12<em>r </em> -12<em>r</em>
What you do on one side you do on both sides
12 on the left cancels out
7<em>a</em>=5.36-12<em>r</em>
/7 /7 /7
Divide 7
7 on the left cancels out
5.36/7=0.76....
left with
<em>a</em>=0.76-12<em>r</em>/7
so the apples cost $0.76 each
to get the cost of the oranges (<em>r</em>) you do the same as you did to get the cost of the apples.
Also on the other equation for 8 oranges and 5 apples you might get different answers but you will see that they are close/similar to the same answers as you will get for the last equations.
Answer:
A. 92% bc 100-8= 92 so 216 animals are 92% of the now 233 animals after 8% increase.
B. 100% bc that is the final # of animals.
Answer: 55.1°F
Step-by-step explanation:
We are informed that there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky, if the plane reaches an altitude of 2,000ft, the drop in temperature will be:
= 1.6° × 2
= 3.2°F
If the temperature on the ground is 58.3°F, then the temperature when the plane reaches an altitude of 2,000 ft will be:
= 58.3°F - 3.2°F
= 55.1°F
Answer:
15 m
Step-by-step explanation:
you would use a sin equation because given the angle, the side you are resting to find is Opposite and the side you are given is the Hypotenuse
sin (32) = a/28
28 x sin (32) = a
14.83 = a
15 m = a when rounded
