Tanya is training a turtle for a turtle race. For every 1/6 of an hour that the turtle is crawling he can travel 1/24 of a mile.
frozen [14]

The rate at which Tanya's turtle travels is 0.25mi/hr

This question is from a topic in mathematics called Rate.

<h3>Rate</h3>

This is a ratio in which different terms in different units are compared against each other.

In this question, for every 1/6 of an hour, the turtle is crawling 1/24 of mile.

Data given;

  • 1/24 miles in 1/6 hour

Let's express this mathematically

1/24 mi = 1/6 hr\\x mi = 1 hr\\x = (\frac{1}{24})/(\frac{1}{6})\\x = 0.25mi

What this calculation shows is that the turtle travels at 0.25mi/hr

The rate at which the turtle travels is 0.25 miles in an hour or 0.25mi/hr

People with diabetes often receive insulin injections. What effect does insulin have on the body?
Gennadij [26K]

The right answer is B.

Insulin is a hormone naturally secreted by the pancreas, specifically by specialized cells located in the islets of Langerhans. It allows glucose (sugar) to pass blood into the cells of the body. These will use glucose as energy or store it for future use.

In healthy subjects, insulin is secreted continuously. The body produces insulin according to the needs and foods consumed. For example, after a meal, the pancreas secretes additional insulin, allowing blood glucose to stay within normal limits.
