Instead, if 40 apples are moved from bag A to bag C then the number of apples in bag A and bag C will be equal. Find the number of apples in bag A and bag C together.
Answer» number of apples in bag A and bag C together. = 1360 Step-by-step explanation: Let SAY Apples in Bag A , B & C are respectively A , B & C If 170 apples are moved from bag B to C, the RATIO of the number of apples in bag A and bag C would be reversed. A /(C + 170) = C/A => A² = C² + 170C 40 apples are moved from bag A to bag C then the number of apples in bag A and bag C will be equal. => A - 40 = C + 40 => A = C + 80 Squaring both sides => A² = C² + 160C + 6400 C² + 170C = C² + 160C + 6400 => 10C = 6400 => C = 640 A = C + 80 = 720 A + C = 640 + 720 = 1360 number of apples in bag A and bag C together. = 1360 Learn more: There are 136 apples,170 MANGOES and 255 oranges .

Three bags A, B and C contain apples. If 170 appies are moved from bag B to C, the ratio of the number of apples in bag A and bag C would be reversed. Instead, if 40 apples are moved from bag A to bag C then the number of apples in bag A and bag C will be equal. Find the number of apples in bag A and bag C together.

Answer»

number of apples in bag A and bag C together. = 1360

Step-by-step explanation:

Let SAY Apples in Bag A , B & C are respectively A , B & C

If 170 apples are moved from bag B to C, the RATIO of the number of apples in bag A and bag C would be reversed.

A /(C + 170) = C/A

=> A² = C² + 170C

40 apples are moved from bag A to bag C then the number of apples in bag A and bag C will be equal.

=> A - 40 = C + 40

=> A = C + 80

Squaring both sides

=> A² = C² + 160C + 6400

C² + 170C = C² + 160C + 6400

=> 10C = 6400

=> C = 640

A = C + 80 = 720

A + C = 640 + 720 = 1360

number of apples in bag A and bag C together. = 1360

Based on the equation, which of the following must be true?A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 59degree Celsius.A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.A temperature increase of 59degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.A) I onlyB) II onlyC) III onlyD) I and II only
Answer» ANSWER:ANSWER EXPLANATION:Think of the EQUATION as an equation for a line y=mx+b where in this case C=5/9 (F−32) or C=5/9 F - 5/9 x 32 You can see the slope of the GRAPH is 5/9 , which means that for an increase of 1 degree Fahrenheit, the increase is 5/9 of 1 degree Celsius. C=5/9(F) C=5/9(1) C=5/9 Therefore, statement I is true. This is the equivalent to SAYING that an increase of 1 degree Celsius is equal to an increase of 9/5 degrees Fahrenheit. C=5/9(F) 1=5/9(F) (F)=9/5 Since 9/5 = 1.8, statement II is true. The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 5/9 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true: C=5/9(F) C=5/9x 5/9 C=25/81 (which is≠1) An increase of 5/9 degree Fahrenheit leads to an increase of 25/81. , not 1 degree, Celsius, and so Statement III is not true. The final answer is D.

Answer»

ANSWER:ANSWER EXPLANATION:Think of the EQUATION as an equation for a line

y=mx+b

where in this case

C=5/9 (F−32)

or

C=5/9 F - 5/9 x 32

You can see the slope of the GRAPH is 5/9

, which means that for an increase of 1 degree Fahrenheit, the increase is

5/9 of 1 degree Celsius.

C=5/9(F)

C=5/9(1)

C=5/9

Therefore, statement I is true. This is the equivalent to SAYING that an increase of 1 degree Celsius is equal to an increase of

9/5 degrees Fahrenheit.

C=5/9(F)

1=5/9(F)

(F)=9/5

Since

9/5 = 1.8, statement II is true.

The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 5/9 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:

C=5/9(F)

C=5/9x 5/9

C=25/81

(which is≠1)

An increase of 5/9

degree Fahrenheit leads to an increase of

25/81.

, not 1 degree, Celsius, and so Statement III is not true.

The final answer is D.

Answer» ${cos}^{2} \alpha - {sin}^{2} \alpha = {tan}^{2} \beta$ To prove ${cos}^{2} \alpha \: - { \sin }^{2} \alpha = {tan}^{2} theta$ Answer: Proved if Cos²θ - Sin²θ = tan²α then Cos²α - Sin²α = tan²θ Step-by-step EXPLANATION: if Cos²θ - Sin²θ = tan²α Then Cos²α - Sin²α = tan²θ LHS = Cos²α - Sin²α = Cos²α(1 - Tan²α) = (1/Sec²α) (1 - Tan²α) Sec²α = 1 + Tan²α = (1/(1 + Tan²α))(1 - Tan²α) = (1 - Tan²α)/(1 + Tan²α) putting VALUE of Tan²α = (1 - (Cos²θ - Sin²θ))/(1 + Cos²θ - Sin²θ) = (1 - Cos²θ + Sin²θ))/(1 - Sin²θ + Cos²θ) USING 1 - Cos²θ = Sin²θ & 1 - Sin²θ = Cos²θ = (Sin²θ + Sin²θ))/(Cos²θ + Cos²θ) = 2Sin²θ/2Cos²θ = tan²θ = RHS Proved

cos square alpha minus sin square alpha equals to tan square beta to prove cos square theta minus sin square theta equals to tan square alpha

Answer»

${cos}^{2} \alpha - {sin}^{2} \alpha = {tan}^{2} \beta$

To prove

${cos}^{2} \alpha \: - { \sin }^{2} \alpha = {tan}^{2} theta$

Answer:

Proved if Cos²θ - Sin²θ = tan²α then Cos²α - Sin²α = tan²θ

Step-by-step EXPLANATION:

if Cos²θ - Sin²θ = tan²α

Then

Cos²α - Sin²α = tan²θ

LHS = Cos²α - Sin²α

= Cos²α(1 - Tan²α)

= (1/Sec²α) (1 - Tan²α)

Sec²α = 1 + Tan²α

= (1/(1 + Tan²α))(1 - Tan²α)

= (1 - Tan²α)/(1 + Tan²α)

putting VALUE of Tan²α

= (1 - (Cos²θ - Sin²θ))/(1 + Cos²θ - Sin²θ)

= (1 - Cos²θ + Sin²θ))/(1 - Sin²θ + Cos²θ)

USING 1 - Cos²θ = Sin²θ & 1 - Sin²θ = Cos²θ

= (Sin²θ + Sin²θ))/(Cos²θ + Cos²θ)

= 2Sin²θ/2Cos²θ

= tan²θ

= RHS
