Lizards can eat 45 ants per minute. To find how many minutes it takes for lizards to eat 1,080 ants, you have to divide the total amount of ants by how many it can eat per minute.

$\frac{1,080}{45}$

Divide 1,080 by 45

$1,080 \div 45 = 24$

It takes lizards 24 minutes to eat 1,080 ants

Use technology or a z-score table to answer the question.

121 of the green beans will be shorter than 13 centimeters.

First, we need to evaluate the expression below to find the z-score.
(13 - 11.2) / 2.1. = 0.86

The matching percent for this z-score is 0.8051.

Multiplying 0.8051 by 150 gives us about 121 green beans.

gladu [14]

Answer:

First and second box had 80 and 75 lb flour originally.

Step-by-step explanation:

Let the two boxes contained x lb and y lb of the flour respectively.

Both the boxes contained 155 lb of flour in total.

So the first equation will be,

x + y = 155 --------(1)

If the 20 lb of the flour is taken out then amount of flour in first box = (x - 20) lb
