siniylev [52]

Answer:

Step-by-step explanation:

ohn will need to sleep for 10.3 hours before his second exam so that the

he average of his two exam scores is an 80.

We were given

8 hours of sleep = 70

To get an average of 80

70+ x = 80

Cross multiply:

70+x = 160

x= 160-70

= 90.

If 8 hours of sleep = 70

x hours of sleep = 90

Cross multiply

8× 90 = 70 × x

720 = 70x

x = 720/70

x = 10.2857

≈ 10.3 hours of sleep

What is the value of s?<br> units

olasank [31]

Answer:

s = 17 units

Step-by-step explanation:

In triangle ABD,

(AB)² + (BD)² = (AD)² (by Pythagoras Theorem)

=> 8² + 15² = s²

=> 64 + 225 = s²

=> s = $\sqrt{289}$

=> s = 17 units

Jagan and Mithun calculated the value of 12 - 6 + 4.The steps are given alongside.

san4es73 [151]

Answer:

Step-by-step explanation:

<u>Explanation:</u>

$12 - 6 + 4$

In order to solve this, we must use PEMDAS.

This is because there are more than one operations involved.

PEMDAS is the order in which you must solve the operations.

PEMDAS STANDS FOR:

Parenthesis
Exponential Notation (exponents)
Multiplication/division (do whichever comes first)
Addition/subtraction (do whichever comes first)

<u>Solve.</u>

Now, using PEMDAS, I will solve.

There are no parenthesis.

There are no exponents.

There is no multiplication nor division.

There is addition and subtraction.

$12-6+4$

$12-6=6$

$6+4$

Lastly, there is addition.

$6+4=10$

<u>Conclude:</u>

I, therefore, believe $12-6+4=10.$

You did not clarify the answers of Jagan nor Mithun.

So, whichever person got the answer of 10 is correct.
