Tonya works 60 hours in 3 weeks. Select ALL the true statements OR YOU WILL FAIL THE GRADE.

tatuchka [14]

Answer: b & c

Step-by-step explanation:

first i found how many hours tonya works in one week which was 20. i got that by dividing 60 by 3. then that set me up for finding the answer to the other problems as well. 60+20=80 so a wouldn’t have worked. 5x5 is 25 and she only worked 20 hours a week. and she would’ve worked 320 hours in 16 weeks, not 240. hope this helps!! :)

$\\ \sf\longmapsto L-M$

Put values

$\sf \left[\begin{array}{cc}\sf 4&\sf 6\\ \sf 5 &\sf 8 \\ \sf 3 &\sf -2\end{array}\right]-\left[\begin{array}{cc}\sf 2&\sf 3\\ \sf 1 &\sf 4 \\ \sf -5&\sf3\end{array}\right]$

Just substract corresponding terms

$\\ \sf\longmapsto \left[\begin{array}{cc}\sf 2 &\sf 3\\ \sf 4&\sf4\\ \sf 8&\sf -5\end{array}\right]$

A scooter was bought at Rs 42,000. its value depreciated at the rate of 8% per annum. find its value after one year

Alona [7]

Answer:

Rs 38,640

Step-by-step explanation:

<u>Pay attention:</u>

$A = P(1+r/100)^n$

The principle (p) : Rs 42,000

Rate of interest (r) : 8%

Time (n) : 1 years

Exact Amount (a) : P(1-R/100)^n

Value:

A = 42,000(1 - 8/100)^1

A = 42,000(1 - 2/25)

A = (42,000 * 23)/25

A = 1,680 * 23

A = Rs 38,640
