A local discount store is famous for their motto, "Shop with us and you'll pay 20% less". Their claim is that every item in the

store is already marked down 20% off of retail prices. In this Sunday's ad, they are advertising a scuba mask and snorkel set at their discount price of $28. Use a percent model to determine the original retail price of the scuba mask and snorkel set.

Answer:

Original retail price: $35

Step-by-step explanation:

20% off means that the discounted price is equivalent to 80% (100% - 20%) of the retail price.  

Calling x the retail price of the scuba mask and snorkel set, then a discounted price of $28 means that this amount of money is 80% of x. Mathematically:

80*x/100 = $28

x = $28*100/80

x = $35

Use percentage multipliers:
$28/0.8 = $35
The original price of the set is $35.

Hope This Helps!

Noah currently has an account balance of $2,976.45. He opened the account 11 years ago with a deposit of $1,963.45. If the inter
Vesnalui [34]
What we know:
Acct. balance A (11)= $2,976.45
Pricipal=$1,963.45
Compounded (n)=quarterly (4)
rate=r
Compound interest formula: A (t)=p (1+r/n)^nt

What we need toi find:
If the interest compounds quarterly, what is the interest rate on the account? Find r.
A (t)=p (1+r/n)^nt
2976.45=1963.45 (1+r/4)^(4×11)
2976.45=1963.45 (1+r/4)^44
2976.45/1963.45=1963.45/1963.45 (1+r/4)^44
1.5159=(1+r/4)^44
(1.5159)^(1/44)=((1+r/4)^44)^(1/44)

1.0095=1+r/4
1.0095-1=1-1+r/4
.0095=r/4
.0095(4)=r/4 (4)
.038=r

Rate = 3.8%

A company is designing a new logo that is comprised of four identical sectors of circles that have central angles
Lyrx [107]
<h3>Answer:  59.7 square inches</h3>

============================================================

Explanation:

The radius of the larger circle is CB = CA+AB = 8+3 = 11 inches.

The area of the larger circle with this radius is...

A = pi*r^2

A = pi*11^2

A = 121pi

The area of the smaller circle (radius CA = 8 inches) is

A = pi*r^2

A = pi*8^2

A = 64pi

The difference is 121pi-64pi = 57pi

This represents the exact area of the full ring. Refer to figure 1 below. Specifically the red region of that figure.

However, we don't want the full ring. We only want a small fraction of it (as figure 2 shows, which is the original diagram your teacher gave you). Specifically, we want (4*30)/360 = 120/360 = 1/3 of the full ring. The 4*30 refers to the idea we have four copies of the 30 degree angle.

So we'll take 1/3 of the 57pi to get (1/3)*57pi = (57/3)pi = 19pi

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

The value 19pi is the exact area of the entire shaded region.

From here, you can use a calculator to determine that

19pi = 19*3.1415926535898 = 59.6902604182061 which rounds to 59.7

If your teacher insists you use pi = 3.14, then 19*pi = 19*3.14 = 59.66 which also rounds to 59.7

NEED FULL EXPLANATION!!
Alchen [17]

Answer:

Step-by-step explanation:

This is a typical probability question where there is a large number of possible outcomes to be considered.

That suggests an approach where we look at the probability of it not occurring.

For that to happen, we have to have 5 coins all landing heads up. The probability of that happening is (1/2)5=1/32.

From this,  we can deduce the probability of that not happening (i.e. there being at least one tail) is  1−1/32=31/32.
