Answer:

C. Antoine can buy 10 pounds or less of oranges. x=10

Step-by-step explanation:

If you take the amount of money he has and subtract $5.20 from it (bc of the pumpkin) you get $13. Then you divide $13 by $1.30. (the amount each pound of oranges cost) He can get either 10 pound or less of oranges with the money he has.

I hope this helped. I'm new to Brainly so I'm trying to help any way I can. Hope this helped you!

1)cot a/2 -tan a/2 = 2 cot a 2) cot b/2 + tan b/2= 2 cosec b prove

VladimirAG [237]

1)

LHS = cot(a/2) - tan(a/2)

= (1 - tan^2(a/2))/tan(a/2)

= (2-sec^2(a/2))/tan(a/2)

= 2cot(a/2) - cosec(a/2)sec(a/2)

= 2(1+cos(a))/sin(a) - 1/(cos(a/2)sin(a/2))

= 2 (1+cos(a))/sin(a) - 2/sin(a)) (product to sums)

= 2[(1+cos(a) -1)/sin(a)]

=2cot a

= RHS

2.

LHS = cot(b/2) + tan(b/2)

= [1 + tan^2(b/2)]/tan(b/2)

= sec^2(b/2)/tan(b/2)

= 1/sin(b/2)cos(b/2)

using product to sums

= 2/sin(b)

= 2cosec(b)

= RHS

Shtirlitz [24]

For this case, the first thing we are going to do is rewrite the equation correctly.
We have then:
T = 50 + (N-40) / 4
We substitute the value of N = 98, we have then:
T = 50 + (98-40) / 4
T = 64.5 degrees Fahrenheit.
Answer:
the temperature in degrees Fahrenheit, T is:
T = 64.5 degrees Fahrenheit.
