Mathematics
1 answer:

Answer:

11 degrees

Step-by-step explanation:

The bottom triangle has 2 given angle, therefore we know the 3rd angle has to be 29 degrees. Given that the 2 lines are parallel, we know that the upper triangle has 140, 29, and x degrees. 180-140-29=x=11 degrees

Hope this helped, feel free to leave a comment if you still have any questions!

Cheers!

Iron Man Training While training for an iron man competition, Tony bikes for 60 miles and runs for 15 miles. If his bikes speed
ivolga24 [154]

Answer:

<u>Tony biked 1 hour 40 minutes and run 3 hours 20 minutes.</u>

Step-by-step explanation:

How long did Tony speed on his bike?

Let s to be Tony's running speed, then 8s is Tony's biking speed

Let's recall that Time = Distance/Speed

Bike time + Running time = 5 hrs

Replacing with the real values, we have:

60/8s + 15/s = 5

8s as Lowest Common Denominator

60 + 8 * 15 = 5 * 8s

60 + 120 = 40s

-40s = -180

s = -180-40

s = 4.5 ⇒ 8s = 36

Tony run at 4.5 mph and biked at 36 mph

Now, we can calculate the time, this way:

Bike time = Bike distance/Bike speed

Replacing with the real values, we have:

Bike time = 60/36

Bike time = 5/3 (Dividing by 12)

5/3 hours * 60 = 100 minutes or 1 hour 40 minutes

Running time = 5 hours - 1 hour 40 minutes = 3 hours 20 minutes

<u>Tony biked 1 hour 40 minutes and run 3 hours 20 minutes.</u>

The amount of Rs 4000 for 2 years is 6000 find the interest.​
Misha Larkins [42]

Interest on the amount is Rs 2000.

Step-by-step explanation:

  • Step 1: Given principal amount = Rs 4000 and amount = Rs 6000
  • Step 2: Formula for Amount, A = Principal, P + Interest, I

⇒ 6000 = 4000 + I

⇒ I = 6000 - 4000 = Rs 2000

Answer:

1. -6 + (-3)

2. 6 + 3

3. -6 + 3

4. 6 + (-3)

Step-by-step explanation:

Given

See attachment

Required

Determine the additive inverse of each

The rule of additive inverse is as follows;

  • For any positive number (n), the additive inverse is (-n)
  • And for any negative number (-n), the additive inverse is (n)

Using the above, the solution is as follows:

1.\ 6 - (-3)

Rule: <em>6 becomes -6 and - (-3) becomes +(-3)</em>

So, the additive inverse is -6 + (-3)

2.\ -6 -3

<em />

Rule: <em>-6 becomes 6 and -3 becomes 3</em>

So, the additive inverse is 6 + 3

3.\ 6 - 3

Rule: <em>6 becomes -6 and -3 becomes 3</em>

So, the additive inverse is -6 + 3

4.\ -6 - (-3)

Rule: -<em>6 becomes 6 and -(-3) becomes +(-3)</em>

So, the additive inverse is 6 + (-3)

<em />
