A suit is on sale for 33% off the sale price is 536 what is the regular price

nataly862011 [7]

Answer: sale: 536

discount: 33%

33/100*536=

Step-by-step explanation:

1- I assume the cost of the suit is $536, not 536%.

So the % of the part times $536= Original price

Remember, $536 is 77% of the original price.

536x0.77=$696.10

Since the suit was 33% off, and since the sale price of the suit was $536

Then the suit was sold for 67% of its original price

Therefore, 67% of its original price (p) equals $536, or .67(p) = 536

.67p = 536

p = 536 � .67 = $800

Original price of suit was $800

Suppose j varies jointly with g and v, and j=2 when g=4 and v=3. <br> Find j when g=8 and v=9.

vladimir2022 [97]

Answer:

$j=12$

Step-by-step explanation:

we know that

In a join variation, If j varies jointly with respect to g and v, the equation will be of the form $j = kgv$

where k is a constant

step 1

Find the value of k

we have

j=2,g=4,v=3

substitute and solve for k

$2 = k(4)(3)$

$2 = 12k$

$k=\frac{1}{6}$

The equation is equal to

$j=\frac{1}{6}gv$

step 2

Find the value of j when g=8,v=9

substitute the values in the equation and solve for j

$j=\frac{1}{6}(8)(9)$

$j=12$

What is the total length of nine pieces of chain each measuring 13 yards, 1 foot, 5 inches? Convert the answer to larger units w

dimulka [17.4K]

Answer: The total length of nine pieces of chain is 121.248 yards.

Explanation:

Since we have given that

Length of each chain = 13 yards, 1 foot, 5 inches

As we know that

$1\ inch=\frac{1}{12}\ foot\\\\5\ inches=\frac{5}{12}=0.4167\ foot\\\\\text{Total foot = 1+0.4167 =1.4167 foot}\\\\And\\\\1\ yard=3\ foot\\\\1\ foot=\frac{1}{3}\ yard\\\\1.4167\ foot=\frac{1.4167}{3}=0.472\ yards\\\\So,\\\\13\ yards+0.472=13.472\ yards$

On Converting it into larger units, we get 13.472 yards

Now, Number of pieces of chain =9

Length of 9 pieces is given by

$13.472\times 9=121.248\ yards$

Hence, Nine pieces of chain are 121.248 yards long .
