Her book was 10 days late. D = days. The equation is .25(4) + .30d = 4.00. First you multiply .25 • 4 to get 1. Then you subtract 1 from both sides and get .30d = 3. Next you divide both sides by .30 to get d = 10.

Answer:

14 days

Step-by-step explanation:

first 4 days= $0.25 x 4 = $1.00

how much money is she left to pay = $4.00 - $1.00 = $3.00

how many days will it take to give the remaining money= $3.00/$0.30=10

so, no of days she borrowed is = 10 +4 =14!!!

How many blocks 1 inch on each edge would it take to fill a shoe box that is 12 inches long, 6 inches wide, and 5 inches tall?
ICE Princess25 [194]
First find the volume of the block(s):
A=s^3
s=side length

A=1^3
A=1 cubic inch

Next, find the volume of the shoe box:
12*6*5 
360 cubic inches

Finally, divide the volume of the larger box by the volume of the block to get how many blocks will fit:

360/1 = 360 blocks

A certain food has a gluten ratio of 13\,\text{mg}13mg13, start text, m, g, end text of gluten per \text{L}Lstart text, L, end t
irina [24]

Answer:

The  gluten ratio in micrograms per milliliter is 13 µg/mL.

Step-by-step explanation:

Consider the provided information.

It is given that the food has a gluten ratio of 13 \frac{mg}{L}.

Now we need to convert gluten ratio in micrograms per milliliter

To convert mg to micro grams use the information shown below:

1 mg = 1000 micro-grams.

1 L = 1000 milliliter

Now, substitute 1 mg = 1000 micro-grams and 1 L = 1000 milliliter in the above ratio.

13( \frac{1000 \ micro-grams}{1000 \ milliliter} )= 13( \frac{micro-grams}{milliliter})

Hence, the  gluten ratio in micrograms per milliliter is 13 µg/mL.
