What is 6 to the second power divided by two times three plus four?

if I bought a laundry basket at $7.50 and it was marked down 20% what would that be and the sales tax is 1% what is the total co

rodikova [14]

Answer:

a) marked-down price = $6.00

b) with-tax cost = $6.06

Step-by-step explanation:

a) The amount of the markdown is ...

0.20 × $7.50 = $1.50

so the marked-down price is ...

$7.50 - 1.50 = $6.00

__

b) The sales tax is ...

0.01 × $6.00 = $0.06

so the total cost with tax is ...

$6.00 + 0.06 = $6.06

_____

Of course, you know that 20% = 20/100 = 0.20, and 1% = 1/100 = 0.01.

Suppose that 35 people are divided in a random mannerinto two teams in such a way that one team contains10 people and the other

Alisiya [41]

To be precise, the size of your sample space is (2410)(2410). This number does go on the bottom of the fraction, and what goes on top is the size of the event. Break up the event into independent events 1. choose the 2 defective bulbs, and 2. choose the remaining 8 bulbs. I don't have much choice in event 1. There is only one way to choose both of the defective balls. In other words, (22)(22) (choosing 2 defective bulbs from a set of 2 defective bulbs). For event 2, there are 24−2=2224−2=22 nondefective bulbs, and I must choose 88 of them, so that's (228)(228). Finally, since events 1 and 2 are independent, we multiply the answers for the combined event: (22)(228)(22)(228)

P=(22)(228)(2410)P=(22)(228)(2410)

Or, since (22)=1(22)=1,

P=(228)(2410)P=(228)(2410)

Hope this helps!

Find the LCM and HCF of 15, 42 and 123

skelet666 [1.2K]

Answer:

LCM - 1

HCF - 3

Step-by-step explanation:

LCM - Lowest Common Factors

HCF - Highest Common Factors

____________________________________________________________

Factors of 15 - 1, 3, 5, 15

Factors of 42 - 1, 2, 3, 6, 7, 14, 21, 42

Factors of 123 - 1, 3, 41, 123

So now we know the factors of 15, 42, 123 what is lowest and highest factor we can find in every number

____________________________________________________________

I have bolded the lowest and highest common factor.

Factors of 15 - 1, 3, 5, 15

Factors of 42 - 1, 2, 3, 6, 7, 14, 21, 42

Factors of 123 - 1, 3, 41, 123

_______________________________________________
