Tell whether the triangle with the given side lengths is a right triangle

14mm, 19mm, 23mm

Answers

Answer 1

Answer:

  not a right triangle

Step-by-step explanation:

The side lengths of a right triangle will satisfy the relation given by the Pythagorean theorem:

  c² = a² +b²

  23² = 14² +19²

  529 = 196 +361

  529 = 557 . . . . . . . . not true; not a right triangle

__

The longest side (23 mm) is too short for a right triangle, so the angle opposite will be smaller than 90°. This is an acute triangle.

If you're doing a bunch of these comparisons, use of a triangle solver app or spreadsheet can help.

Answer:

Fraction form: [tex]\frac{3}{2}[/tex]
Decimal form: 1.5
Mixed number form: 1 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Find the greatest common factor between the two numbers in the fraction, in this case the largest number both can be divided by equally is 2, so,

Take [tex]\frac{6}{4}[/tex] and divide both parts by 2:

6 ÷ 2 = 3

1 yard (yd) = 3 feet (ft); 1 foot (ft) = 12 inches (in) how many inches are there in 5 yards?

Answers

Answer: 180 inches

Step-by-step explanation:

We can use dimensional analysis. Our desired units are inches per yard. Begin by writing down:

[tex]\frac{12in}{1ft}[/tex]

Then use the conversion factor of feet to yard. The units of feet will cancel giving:

[tex]\frac{12in}{1ft} *\frac{3ft}{1yd}=\frac{36in}{1yd}[/tex]

Multiply the top and bottom by 5 to get:

[tex]\frac{36in}{1yd} *\frac{5}{5} =\frac{180in}{5yd}[/tex]

2(LB+BH+LH)2(12×6+5×6+12×5)2(72+30+60)2(162)324in²

Answer:

D. 324 in²

Step-by-step explanation:

Given :

Length of shoebox = 12 in

width = 6 in

height = 5 in

The Total surface area of cuboid = 2(lw + lh + wh )

=> 2 (12×5 + 12×6 + 5×6 )

=> 2( 60 + 72 + 30 )

=> 2( 162)

=> 324 in²

To find the volume of a triangular prism:

 ⇒ necessary to know the formula

     [tex]Volume = (Area-of-Triangular- base)*(length)[/tex]

Let's first find the area of the triangular base:

 ⇒the formula for the finding the area of a triangle is ⇒ [tex]\frac{1}{2}bh[/tex]

b: length of base --> 3mmh: length of height: 6mm

     Area of the triangle is  [tex]\frac{1}{2}*3*6=3*3=9[/tex]

Since the area of the triangular base is 9 and the length is 5.22

 ⇒ the volume is:

         [tex]Volume = 9 * 5.22=46.98mm^3[/tex]

When the volume is rounded to the nearest tenth, the volume is 47.0 [tex]mm^3[/tex]

Hope that helps!

use Mental Math to determine if the circumference of a circle with a radius of 5in will be greater than or less than 30 in write an argument that can be used to justify your solution​

Answers

Answer:

It will be greater than 30.

Step-by-step explanation:

(Any following math is easy to do in your head and therefore mental math.)

In order to find the circumference, you multiply the diameter by pi.

The radius is half of the circumference so if you double the radius you get the circumference.

5 × 2 = 10

The default for pi is 3.14, so it's a little more than 3.

10 × 3 = 30

If just 3 is 30, then anything more ( like the 0.14), will make it over 30.

Answers

Answer:

A=p2-2p-3

Step-by-step explanation:

The area for a triangle is given by:

A=1/2bh

The base is p + 1 and the height is 2p - 6. Therefore:

A=1/2(p+1)(2p-6)

Simplify the second term:

A=(p+1)(1/2)(2p-6)=(p+1)(p-3)

Distribute:

A=p(p-3)+1(p-3)

Distribute:

A=p2-3p+p-3

Combine like terms:

A=p2-2p-3

The third ordered pair using the two sequences as described in the task content is; (two and one third, 106).

What is the third ordered pair of the two sequences?

It follows from the description of the task content that the third ordered pair of each sequence is as follows;

Sequence 1; 0(2)+1/3 = 1/3(2) + 1/3 = 1(2) + 1/3 = 2 1/3.

Sequence 2; (1+1/2)4 = (6+1/2)4 = (26 +1/2)4 = 106.

On this note, it follows that the required ordered pair is; (two and one third, 106).
