I need to make a triangle. One side is 12 feet and the other is 8 feet. Identify each value that could NOT be the length of the third side.

7 feet
12 feet
20 feet
23 feet
5 feet
19.9 feet
4 feet

Answers

Answer 1

Answer:

20 feet, 23 feet, 4 feet could NOT be the length of the third side ⇒ C, D, G

Step-by-step explanation:

In any triangle

The length of each side should be greater than the difference of the lengths of the other two sidesThe sum of the lengths of any two sides greater than the length of the 3rd side

∵ One side is 12 feet and the other is 8 feet

→ Find their difference and sum

∵ Their difference = 12 - 8 = 4 feet

∵ Their sum = 12 + 8 = 20 feet

→ By using the rules above

∴ The length of the third side is between 4 feet and 20 feet

4 < third side < 20

∵ 7 feet, 12 feet, 5 feet, 19.9 feet are between 4 feet and 20 feet

7 feet, 12 feet, 5 feet, 19.9 feet could be the length of the third side

∵ 20 feet, 23 feet, 4 feet are not between 4 feet and 20 feet

20 feet, 23 feet, and 4 feet could NOT be the length of the third side

Hi just wanted to know if 4/17 is a rational number or not. I think it's irrational because the decimals are unending different sets of numbers and a type of number that can not be put into fraction. But, savemyexams says its a rational number because its decimal is 0.23, but I checked the calculator, unless a characteristic of a rational number is to be able to turn it into decimal.. (but so can pie- 3.14,)

Answers

Answer:

4/17 is a rational number

Step-by-step explanation:

It does not matter with the outcome of the fraction for being a rational number or irrational.  that is why a fraction before its outcome is a rational number.

Given that,
To determine whether the fraction 4 / 17 is a rational number or an irrational number.

What is a rational number?

In mathematics, a rational number is a number that can be described as the result of a fraction of value or does not have face value.

What are irrational numbers?

An irrational number is a type of real number which cannot be represented as a simple fraction or the values that have face value are irrational numbers. Example: √2, √3, and π are all irrational.

Here,
4 / 17 is a rational number because every fraction, where the numerator and denominator is a natural number is a rational number so we don't, have to divide or perform operations to know whether a fraction is rational or irrational.
4 / 17 = rational number but
4 / 17 = 0.23529441
this 0.2352944 is an irrational number.

Thus, 4 / 17 is a rational number but its outcome is an irrational number.

Rewrite the whole as a fraction using  5  as the denominator :

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 n+25

 ———— • 5 = 0 • 5

  5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  n+25  = 0

7.2      Solve  :    n+25 = 0

Subtract  25  from both sides of the equation :

What is m2+m3?
Pls help ASAP lol

Answers

Answer:

ABC has m1 = 90⁰

=> ABC is a right triangle at A

=> m2 + m3 = 90⁰

Answer:

90 degrees

Step-by-step explanation:

Ok so basically, first you see that angle 1 and a right angle are on a line together, and the angles on a straight line always have to add up to 180 degrees. This means that angle 1 = 180-90 = 90.

There's no way to tell the exact angle measure of angle 2 and angle 3, but you can figure out the sum. Since the interior angles of a triangle have to add up to 180, that means that 180 - 90(angle 1) = 90 for the sum of angle 2 and angle 3.

Answers

Answer:

A. 32 = 3x - 5

Step-by-step explanation:

2x-5

2x + x = 3x

3x - 5

32 - 5 = 27

27 divided by 3 = 9

This can be used to find the value of x.

Answer:

C) 32=6x-10

Step-by-step explanation:

As, a perimeter of a rectangle = 2 ( length + breath)

So, 32cm = 2 ( (2x - 5) + x) = 2(2x-5) + 2(x)

= 32cm = 4x - 10 + 2x = 6x - 10

Answers

Answer:

Step-by-step explanation:

8.5

According to the IQR rule, values greater than 20 hours are outliers. Hence, a value such as 21 is an outlier.

The IQR rule :

Outliers are defined thus :

Q1 - 1.5(IQR)

Q3 + 1.5(IQR)

The IQR = Q3 - Q1 :

Q3 = 11 ; Q1 = 5

IQR = 11 - 5 = 6 hours

Outlier above the Upper boundary:

Q3 + 1.5(IQR)

11 + 1.5(6) = 11 + 9 = 20 hours

Outlier below the Lower boundary :

Q1 - 1.5(IQR)

5 - 1.5(6) = 5 - 9 = - 4 hours

Therefore, values below - 4 or greater than 20 are outliers. Hence, a value greater than the median and would be an outlier is 22 hours

Myra made a scale drawing of an office building. In real life, a desk is 6 feet long. It is 10 inches long in the drawer. What is the scale of the drawing

Answers

Answer:

1in : 0.6ft

Step-by-step explanation:

Since the desk is 10 inches in the drawing but 6 feet long in real life then the scale would be 10in : 6ft. This would be the scale of the drawing but we need to simplify it to its most simplest form. We do this by dividing both sides of the scale by 10 so that the left side is equal to 1.

10 / 10 = 1 inch

6 / 10 = 0.6 ft

1in : 0.6ft

Finally, we can see that the scale of the drawing is 1in : 0.6ft

A car purchased in 2014 was worth $21,000. It has depreciated at an annual rate of 8.5%. what will its value be in 2021?

Round answer to the nearest penny (100th)

Answers

Answer: The value of the car in 2021 will be $11,276.31.

Step-by-step explanation:

If r is the depreciation rate and P is the initiial amount , then the amount after t years is given by:-

[tex]A=P(1-\dfrac{r}{100})^t[/tex]

Given: P=21000, r=8.5%  , t= 2021-2014= 7

Plug all the values in the formula, we get

[tex]A= 21000(1-\dfrac{8.5}{100})^7\\\\\Rightarrow\ A=21000(1-0.085)^7\\\\\Rightarrow\ A= 21000(0.915)^7\\\\\Rightarrow\ A= 21000(0.5369670)\approx11276.31[/tex]

The value of the car in 2021 will be $11,276.31.
