find the elasped time from 10:11 to 5:34 pls show your work . A) 5hrs and 37mins , B) 4hrs , C) 5h 23mins , D) 4hr 37mins
Bingel [31]
The question as you wrote it doesn't fit the answers. However, one of the answers fits if you meant
"elapsed time from 5:34 to 10:11".

There are many ways to do this. Try first taking the time from 5:34 to 6:11, and after that finding the time from 6:11 to to 10:11.

In a way, 6:00 is the same thing as 5:60. Add 11 to that and you can see that 6:11 is the same as 5:71. Now that you have an easy way to find the time from 5:34 to 6:11.
6:11 - 5:34 isn't easy.
But 5:71 - 5:34 is quite easy. 71 - 34 is 37.

So, from 5:34 to 6:11 there are 37 minutes.

Now the easy part, finding the time from 6:11 to 10:11. Since the minutes are the same, just subtract the hours. 10 - 6 = 4 hours.

Now you have the hours and minutes, which number 4 hours and 37 minutes.

What is the product?<br> (38b* )-822
sergey [27]

Answer:

\boxed{\sf D)\:-24a^3b^7}

Step-by-step explanation:

\sf (3a^2b^4)(-8ab^3)

We'll use rule of exponents to simplify expression.

\sf 3^1a^2b^4(-8)^1a^1b^3

Now, use the commutative property of multiplication.

\sf 3^1(-8)^1a^2a^2b^4b^4

In order to multiply power of the same base, we add their exponents.

\sf 3^2(-8)^1a^{2+1}b^{4+3}

→ Add exponents:

\sf 3^1(-8)^1a^3b^7

→ Multiply 3* -8

\sf -24a^3b^7

Leni [432]

Answer:

Sin, Cos, Tan and others are used to calculate the ratios of the sides of a right angled triangle by taking a certain angle as the angle of reference.

On the other hand, Sin‐¹, Cos‐¹ and Tan-¹ are used to find the reference angle used to calculate the ratio of sides.

For this question,

we need to find which option should used to calculate the angle the slide makes with the vertical support.

So the option will have to be either A, C or E.

here, the base is 2.81m and hypotenuse is 3.64m.

we know, Cos = base / hypotenuse

So the angle is given by Cos-¹(2.81/3.64)

Option C

A racecar travels 225 miles per hour. How far will it drive in 6 1/2 hours?
saul85 [17]

Answer:

1462.5

Step-by-step explanation

225 mph means of course 225 miles per hour

225 x 6 is 1350 and then you have to do 225/2 which is 112.5 to find what half of 225 is then you add 1350+112.5 to get 1462.5
