Answer: the original temperature is

123 °Fahrenheit

Step-by-step explanation:

The temperature dropped 11 Fahrenheit per hour from the original temperature. This means that the rate at which it is dropping is in arithmetic progression.

The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + d(n - 1)

Where

a represents the first term(original temperature) of the sequence.

d represents the common difference.

n represents the number of terms(hours) in the sequence.

From the information given,

d = - 11 degrees (it is decreasing)

When n = 4 hours, T4 = 90

We want to determine the value of the first term, a. Therefore,

T4 = 90 = a - 11(4 - 1)

90 = a - 11 × 3

90 = a - 33

a = 90 + 33

a = 123 °Fahrenheit

Cade and Tyce both tried to find the missing side of the right triangle. A right triangle is shown. The legs are labeled 6 and 9
Talja [164]

Step-by-step explanation:

Two legs of the right triangle are 6 and 9. We can find its third side as follows :

a^2+b^2=c^2

The above is called Pythagoras theorem and it is applicable for a right angled triangle.

a,b and c are base, perpendicular and hypotenuse respectively

c is the third side

So,

c^2=6^2+9^2\\\\c=\sqrt{117} \\\\c=10.816\approx 10.82

Hence, Cade and Tyce both are correct. The length of the missing side is 10.82

What is the recursive formula for -7,-1,5,11
Lostsunrise [7]
-1 - (-7) = 6
5 - (-1) = 6
11 - 5 = 6
The common difference is 6.
If you add 6 to a term, you get the next term.

a_0 = -7

a_n = a_{n - 1} + 6

What is an estimation strategy<br> This is for 6th grade math please help
Lunna [17]

Answer:

Estimation is a mental process of coming up with an answer that is relatively  close, to allow decisions to be made. The types of estimation are quantity, computation and measurement.

An estimation strategy is simply coming up with a good estimate based on evidence and already known facts. Coming to a conclusion as close to the real answer as you can. It can also be called an educated guess.
