Answer:

4 kg

Step-by-step explanation:

so 1.6 * 4 is 6.4 so you just double check if you want

4 + 1.6 which is 1/4 of 6.4 will be 5.6 (matches with the question)

4 + (1.6*4) (indicates it's full) = 10.4( also Matches with the question)

there is another way by setting up an equation. let me know in comments if you want to see it that way

Which do you think will have a greater value, 1/8 of one pound gold or 1/4 of lead? Why?
Ivenika [448]
<span>if you multiply 1/8 by 4, the fraction become 4/32, and if you multiply 1/4 by 8 you get 8/32.Since both fractions have the same denominator, we can find which fraction has the greater value. Since 1/4(8/32) has a greater numerator, the 1 pound of lead will have a larger value.</span>

You want to buy a jacket that is $75. Today it is marked down 33 one-third percent. The sales tax is 8%. How much will you pay?
lara [203]

Answer:

$54

Step-by-step explanation:

Price of jacket = $75

Markdown = 33.33...%

Sales tax = 8%

First we have to find the price of the jacket after the markdown.

75-33.33(75)

75-(25)

50

New price of jacket = $50

Now to calculate the price with sales tax.

50+0.08(50)

50+(4)

54
