First get the difference between the 2008 price and 1990 which is $4.02-$1.37= $2.65. Then the difference you've got which is $2.65, divide it to the current market price which is $4.02 to get the how many percentage it increased since then, $2.65/$4.02= 0.65920398 then multiply it to 100. It would be 65.92 or 66% if rounded off to whole number.

Dan rolls 2 fair dice and adds the results from each. Work out the probability of getting a total more than 3.
faust18 [17]

Answer:

the answer is 6/12 or 1/2

Step-by-step explanation:

so in a dice there are 6 sides as in 6 numbers so we can say

6×2= 12 sience the dice was rolled 2 times

then count all the numbers which is greater than 3

they are: 4, 5, 6

these 3 numbers ×2

3×2=6

so now the probability of this is 6/12

now we can reduce this

6/12= 3/6= 1/2

A picture measuring 2.5" high by 6" wide is to be enlarged so that the width is now 18 inches. How tall will the picture be?
viktelen [127]
We have that
the picture original is 2.5 in x 6 in
high=2.5 in
wide=6 in

the picture <span>enlarged  is
</span>high=2.5*x
wide=6*x-----> 6*x=18--------> x=18/6----------> x=3
x is the factor scale
so
high=2.5*x-----> 2.5*3----> 7.5 in

the answer is
7.5 in

Mary earns $28,000 a year plus commission. One week she grossed $655.58. She had sold $1673.19 worth of merchandise. What is the
insens350 [35]

Answer:

Step-by-step explanation:

The parameters given are;

The amount Mary earns annually = $28,000

The amount Mary grossed during a week = $655.58

The amount Mary had sold during the week to make the amount grossed during the week = $1673.19

Given that Mary makes $28,000 per year

Therefore;

The amount Mary earns per week = Amount earned per year/52

The amount Mary earns per week =  $28,000/52 = $538.46

The amount extra she made on commission = $655.58- $538.46= 1$117.12

The commission rate = Commission earned/(Amount of merchandise sold)×100

The commission rate = 117.12/1673.19 × 100 = 6.99%

Her commission rate = 6.99%
