The correct answer is 50 minutes. Since Carla can read 4 pages in 10 minutes, she will need to read 20 pages which is 5 times 4 pages. Therefore, it will take her 5 times 10 minutes which is 50 minutes to read the full assignment.
To find out how long it will take Carla to read the full assignment, we first need to calculate how many groups of 4 pages are in 20 pages. We can do this by dividing 20 by 4:
20 pages ÷ 4 pages/group = 5 groups
So, Carla will need to read the assignment in 5 groups of 4 pages each.
Since it takes Carla 10 minutes to read 4 pages, we can multiply 10 minutes by the number of groups she needs to read:
10 minutes/group × 5 groups = 50 minutes
Thus, it will take Carla 50 minutes to read the full assignment.
To find out how long it will take Carla to read the full assignment, we need to determine how many sets of 4 pages are in 20 pages.
20 pages / 4 pages = 5 sets
Since Carla takes 10 minutes to read 4 pages, it will take her 10 minutes * 5 sets = 50 minutes to read the full assignment.
Therefore, the correct answer is: 50 minutes
Luis is making chocolate chip cookies. The recipe calls for 18 cup of almonds for every 34 cup of chocolate chips. If Luis uses 3 cups of chocolate chips, how many cups of almonds will he need? Round to the nearest tenth.(1 point)

To find out how many cups of almonds Luis needs, we can set up a proportion using the ratio of almonds to chocolate chips.
The ratio of almonds to chocolate chips is 18 cups to 34 cups.
Let x represent the number of cups of almonds Luis needs.
We can set up the proportion:
18 cups / 34 cups = x cups / 3 cups
Cross-multiplying, we get:
18 cups * 3 cups = 34 cups * x cups
54 cups = 34x
Dividing both sides by 34, we get:
x = 54 cups / 34
Simplifying, we get:
x = 1.588 cups
Rounding to the nearest tenth, Luis will need approximately 1.6 cups of almonds.
Thus, the correct answer is: 1.6 cup

Lenny is making his own laundry soap. The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes. If Lenny uses 7 cups of soap flakes, how many cups of borax and washing soda combined does he need?(1 point)

Since the recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes, the borax and washing soda combined will be 4 parts in total.
If Lenny uses 7 cups of soap flakes, then he would need 4 times that amount in total for the borax and washing soda.
4 * 7 cups = 28 cups
Therefore, Lenny would need 28 cups of borax and washing soda combined.
The correct answer is: 28 cups
