Question
Evaluate.

−26.6
-----------
−1

Enter your answer in the box.

Answers

The value of the expression given as −26.6/−1 is 26.6

How to evaluate the expression?

The expression is given as

−26.6

-----------

−1

Rewrite the above expression properly as follows

So, we have

−26.6/−1 or −26.6 ÷ −1

This is so because the expression is a quotient expression

So, we have

−26.6/−1

Express −26.6 as -13.3 - 13.3

So, we have the following equation

−26.6/−1 = (−13.3  −13.3)/−1

Expand the expression

So, we have

−26.6/−1 = (−13.3)/−1 + (−13.3)/−1

Evaluate the quotients in the above equation

So, we have

−26.6/−1 = 13.3 + 13.3

Evaluate the quotients in the above equation

So, we have

−26.6/−1 = 26.6

Hence, the value of the expression given as −26.6/−1 is 26.6

A = 47

B = 62

C = ???

We don't know what "C" is??

So..

A + B + C = 180

C = 180 - A - B

C = 180 - 47 - 62

Subtract those numbers and you should get 71

What is the length of a missing side of a geometric system?

Herein we find the a geometric system formed by a circle and an inscribed  right triangle formed by two right triangles. By a quick inspection we find the following measures:

AD = 10π, m ∠ BCD = 60°, m ∠ BDC = 30°, m ∠ BDA = 60°, m ∠ BAD = 30°

Then, by 30-60-90 right triangle theorem we find that:

DB = (1 / 2) · AD

DB = (1 / 2) · 10π

DB = 5π

DB = √3 · BC

BC = (√3 / 3) · DB

BC = 5√3 π / 3

Describe the graph of the Celsius-Fahrenheit relationship

Answers

Using linear function concepts, the graph of the Celsius-Fahrenheit relationship is linear with an intercept of 32 and slope of 1.8.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

From the table, we have that:

When the input is of 0, the output is of 32, hence the intercept is of 32.When the input changes by 10, the output changes by 18, hence the slope is of 18/10 = 1.8.

Thus, the graph of the Celsius-Fahrenheit relationship is linear with an intercept of 32 and slope of 1.8.

Remote Interior and Exterior Angles in Triangles

Answers

Answer:

∠ 2 = 60°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 remote interior angles.

123° is an exterior angle of the triangle , then

∠ 2 + 63° = 123° ( subtract 63° from both sides )

∠ 2 = 60°

Answer:

60

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180° so we can write the following equation to find the value of missing angle:

∠2 + 63 + 57 = 180 add like terms

∠2 + 120 = 180 subtract 120 from both sides

We have,

A rectangle:

Length = 15 miles

Wide = 5 miles

Diagonal length can be considered as the hypotenuse.

Applying the Pythagorean theorem.
