Arian is making bracelets. For each bracelet, it takes 1/10 of hour to pick out materials and 1/4 hour to braid it together. How

-Dominant- [34]

Change everything into 10ths as follows:

1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.
Divide your time available by the time it takes to make one.

How do you explain a diameter of 0.00085 inches using scientific notation

dezoksy [38]

Answer:

8.5 $E^{-4}$ inches

Step-by-step explanation:

Scientific scientific notation is where the super small / super large number is multiplied by a 10 (E) to the power of a number. Here, the number is smaller than 8.5 so our power must be negative. As we are making it four "places" bigger, we use the exponent of -4.

Hope this helps, have a nice day! :D

Answer:

Part a) The raisins cost $0.8 per ounce

Part b) 1.25 ounces

Step-by-step explanation:

The correct question is

b) How many ounces of raisins can be bought for $1?

Part a) How much do raisins cost per ounce?

we know that

To find out the unit rate divide the total cost by the total weight

$\frac{4}{5} =\$0.8\ per\ ounce$

therefore

The raisins cost $0.8 per ounce

Part b) How many ounces of raisins can be bought for $1?

we know that

The raisins cost $0.8 per ounce

using proportion

Find out how many ounces of raisins can be bought for $1

Let

x -----> the ounces of raisins

$\frac{1}{0.8}=\frac{x}{1}\\\\x= 1.25\ ounces$
