The number of practice hours per week for Maranda's piano recital is 13 hours

Overall practice hours = 52 hours

Number of weeks of practice = 4 weeks

Since, the number of practice hours per week is the same ;

Number of hours practiced each week can be obtained by dividing the overall practice hours by the number of weeks of practice.

Number of practice hours per week = Overall practice hours ÷ Number of weeks of practice

Number of practice hours = (52 ÷ 4) = 13 hours

Therefore, Marana practiced for 13 hours each week.

Summer spent $55.60 on clothes before sales tax. If sales tax is 7.5%, what did Summer spend with tax included?  *Add Explanatio
vampirchik [111]
$59.77. Turn the percent into a decimal by moving the decimal to the left two places (7.5 to 0.075). Then multiply the new decimal by the cost (55.60×0.075=4.17). 4.17 would be the total sales tax, so then add it to the price (55.77+4.17=59.77). Hope that helped.

WHAT ARE THE SPECIFIC RULES FOR PROVING SIMILARITY IN TRIANGLES? EXPLAIN.
weeeeeb [17]

Answer:

AAA (Or even just two angles work too, since the last has to be the same no matter what) ASA and SSS

Step-by-step explanation:

I believe this is the same as before? As far as I know these are the main rules for proving similarity. (AAS and A** do not exist (Brainly won't let me say the two Ss), make sure no trick questions get you ;p)

I'm not sure if what you needed earlier was the relationships between angles to find them? Like to find Exterior Angles subtract <C from 180 = <EA?

Minny has two coupons, but can use one of them. The first one is for $5 off an item; the second coupon is for 20% off an item. T
joja [24]
Let's first solve for the $5 off coupon,

28 - 5 = 23

The final total is $23.00 with $5 off.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Now for the final price of the 20% off coupon,

20\% = 0.2

0.2 or 0.20 is decimal form of 20%. Easier to multiply than in percent form!

0.2 \times 28 = 5.6

$5.6 or $5.60 is 20% of 28, we're not done yet!

Lastly, subtract 20% off of 28 (5.6) from 28,

28 - 5.6 = 22.4
$22.4 or $22.40 is the final after 20% off!

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Q. Which is less after the discounts??

$23.00 or $22.40

A. $22.40 of course which was the 20% off.

Part A : Which coupon should she use ?

Answer : Well, to get a lower price, less to pay, the 20% off coupon is better!

Part B: How much money will she save by using the better coupon?

Answer : $5.6 / $5.60 is the amount she'll save!

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

I hope that helps you out!!

Any more questions, please just ask me!!
