An airplane flies in a straight line for 5 hours & then takes a turn 12 degrees to the right & flies 3 hours in the new direction. The plane maintained a constant speed of 550 miles per hour throughout the flight. How far is the plane from the starting point in the air at the end of this time? (could someone pls explain this lol -3-)

Answers

Answer 1

Answer: we have triangle with side 5*550 = 2750 and side 3*550=1650 and angle 180-12 = 168 between them
Now we use the cosine theorem to get third side

$d = √(2750 ^2+1650^2-2*1650*2750*cos(168)) = 4 377.40670603041$

4(a-1) -5 =3a + 7

Answers

Distributive property says 4 * a and 4 * -1 so 4a - 4 - 5 = 3a + 7
Now do the simple subtraction
-4 - 5 = -9
Then add 9 and subtract 3a Remember: Always do the opposite operation to both
sides. So you have a = 16

$4\cdot(a-1)-5=3a+7\n\n4\cdot a-4\cdot1-5=3a+7\n\n4a-4-5=3a+7\n\n4a-9=3a+7\ \ \ /+9\n\n4a-9+9=3a+7+9\n\n4a=3a+16\ \ \ \ /-3a\n\n4a-3a=3a-3a+16\n\na=16$

On an uphill hike Ted climbs at 3mph. Going back down, he runs at 5mph. If it takes him forty minutes longer to climb up than run down, then what is the length of the hike? if possible, I would like a clear equation.

Answers

Answer:

He hiked 10 miles.

Step-by-step explanation:

rate x time = distance

The distance up and the distance down are equal

3 mi/1 hr x (h hours + 2/3 hr) = 5 mi/1 hr x h hours

3h + 2 = 5h

2 = 2h

h = 1 hour

3mi/hr x 1 2/3 hr = 5 miles

5 mi/hr x 1 hr = 5 miles

How do you calculate the daily periodic rate?

Answers

Answer:

First we need to know what's APR.

APR refers to a annual periodic rate that's charged in a credit card. It changes depending on the company. So, the daily periodic rate can be calculated by dividing the APR of the credit car by 360 or 365, depending on the credit card companies.

So, basically, you need to call the company and ask about the APR and ask if the use 360 or 365 days to calculate the daily periodic rate, then do the division.

A daily periodic interest rate is calculated by dividing the annual percentage rate, or APR, by either 360 or 365, depending on the card issuer.

Solve the inequality 0 > –3x – 2x. A. x > –36
B. x > 1
C. x > 0
D. x > –28

Answers

Answer:

Option C is correct.

Step-by-step explanation:

Given Inequality,

0 > -3x - 2x

To Find: Solution of the inequality.

Consider,

0 > -3x - 2x

Group like terms in RHS

0 > ( -3 - 2 )x

0 > -5x

transpose RHS to LHS and LHS to RHS

-5x < 0

Divide both sides by -5

we know that in inequality multiplying and dividing negative number sign of inequality changes.

So,

x > 0/(-5)

x > 0

Therefore, Option C is correct.

0 > -3x - 2x...combine like terms
0 > - 5x ....divide both sides by -5
0/-5 < x
0 < x or x > 0

How to estimate 518 + 372

Answers

Answer:

900

Step-by-step explanation:

518+372

We have to find the result by estimation

Estimate both the numbers to nearest hundreds

518 is estimated to nearest hundred= 500

372 is estimated to nearest hundred= 400

After adding, 500 and 400, we get

500+400=900

we get our answer 900

Hence, the correct answer is 900

It is 890 but if you estimate it would be 900
