Question:

Write an inequality to represent the situation.

A light bulb is programmed to turn on

when the temperature in a terrarium is

72°F or cooler.

Answer:

t ≤ 72⁰F

Step-by-step Explanation:

Given this situation, we can write an inequality to represent the temperature in a terrarium at which the light bulb is programmed to turn on as follows:

t ≤ 72⁰F

where, t is the temperature of the terrarium, the sign "≤" implies that at a temperature of 72⁰F and below (i.e. colder would mean temperature below 72⁰F), the light bulb should turn on, as programmed.

Invariably, the inequality "t ≤ 72⁰F" mean the light bulb would turn on if the temperature of the terrarium is less than or equals 72⁰F.

What pattern exists in the three places in each period?

alukav5142 [94]

Answer:

the pattern is (hundreds, tens, ones)
963 thousand 104

Step-by-step explanation:

a) Each place in our decimal place-value number system has a name. In the number 356,039, the left-most digit 3 is in the hundred-thousands place, so it is read (by itself) as "three hundred thousand." Together, the digits 356 of that number signify three hundred fifty-six thousand. They are said to be in the "thousands period." Each period of three digits will be grouped like that to specify the number of hundreds, tens, and ones in the period.

b) The given expanded form adds up to give ...

963,104

Based on the above discussion, the name of this number is ...

"nine hundred sixty-three thousand one hundred four"

Using digits to help write this, it would be 963 thousand 104.

An observer (O) is located 660 feet from a tree (T). The observer notices a hawk (H) flying at a 35° angle of elevation from his

wolverine [178]

We use tan.

tan 35 = x/660

multiply both sides by 660

660 tan 35 = x <------------------ANSWER

x = 462.13 ft
