- 3.9 / 1.3 = - 3/1 = - 3



Calculation Steps:


Conversion:


3.9 = 39/10



Unary Minus:


- 3.9 = - 39/10



Conversion:


1.3 = 13/10




Divide:


- 39/10 : 1.3


= - 39/10 * 10/13


= - 39 * 10/ 10 * 13



= - 390/130



= - 3





Answer: - 3





Hope that helps!!!! Answer: - 3

The target temperature for a laboratory is 72° Fahrenheit. It
myrzilka [38]

The inequality |t - 72| ≤ 2 represents the target temperature for a laboratory is 72° Fahrenheit, and it can vary by up to 2° option (D) is correct.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

The question is incomplete.

The complete question is in the picture, please find the attached picture.

We have:

The target temperature for a laboratory is 72° Fahrenheit. It can vary by up to 2°.

Target temperature = 72 degree Fahrenheit

It can vary by up to 2°. (the highest limit)

The temperature in the laboratory represented by t

Now,

inequality represents this situation is:

|t - 72| ≤ 2

Thus, the inequality |t - 72| ≤ 2 represents the target temperature for a laboratory is 72° Fahrenheit, and it can vary by up to 2° option (D) is correct.

Given the area of a trapezoid is 86 in’, and the height is 4 in. If one base is 18 in, determine the other base.
Rus_ich [418]

Answer:

25 = base

Step-by-step explanation:

I searched all of this on YT to try and help

so first we need to know the area of a Trapezoid

A = 1/2h(b + b)

86 = 1/2(18 + b)4

we dont know the base where going to put b

we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.

172 = (18 + b)4

the 4 is multipling so divide it on both ends.

43 = (18 + b)

then do the opposite operation on the 18, by subtracting 18 on both sides.

25 = b

is the base

check the work by plugging it back in

A = 1/2h(b + b)

A = 1/2 4(18+25)

A = 1/2 4(43)

A = 1/2(172)

A = 86in
