The regular price rounded to the nearest cent

Mathematics
1 answer:
Daniel [21]3 years ago
3 0

Answer:

$189.43

Step-by-step explanation:

To find the original price, write a proportion. In your proportion, write one ration that has sale price over original price. The other ratio should be written with the corresponding percent values. Since the sale price is 65% off then you paid 35% of the regular the price. The proportion should be:

\frac{66.30}{x}= \frac{35}{100}

To solve cross multiply numerator and denominator of each fraction.

66.30(100) = x(35)

6630 = 35x

189.43 = x

This means the regular price is $189.43.

The mean of 10 values is 19. If further 5 values are
Leokris [45]

Answer:

22

Step-by-step explanation:

Pretend the 10 values in the first sentence are a,b,c,d,e,f,g,h,i,j

Pretend the addition 5 values is k,l,m,n,o

So the mean of all the 15 data is (a+b+c+d+e+f+g+h+i+j+k+l+m+n+o)/15=20

So the sum of all 15 data is  a+b+c+d+e+f+g+h+i+j+k+l+m+n+o=300                since 15(20)=300

Now let's look at the first 10:  We have their mean so we can write:

(a+b+c+d+e+f+g+h+i+j)/10=19

so a+b+c+d+e+f+g+h+i+j=190                               since 10(19)=190

So that means using our first sum equation and our equation sum equation we have

190+k+l+m+n+o=300

      k+l+m+n+o=300-190

      k+l+m+n+o= 110

So the average of those 5 numbers mentioned in your problem is 110/5=22

luda_lava [24]

Cone Volume = PI * radius^2 * height / 3, which can br rewritten as

Cone Volume = base area * height / 3

Cone Volume = 420mm * 60

Cone Volume = 25,200 cubic mm

What is the greatest<br> common factor (GCF) of 16<br> and 21
viktelen [127]

Answer:

1

Step-by-step explanation:

Let's start by prime factorizing (finding the prime factors) of 16 and 21:

16=4*4=2*2*2*2=2^4

21=3*7

We can see that they DO NOT have any common factors, meaning that their greatest common factor is 1.
