A triangle has sides with lengths of 17 inches, 20 inches, and 28 inches. Is it a right triangle?
Answer:
no
Step-by-step explanation:
Pythagoras theorem
a2 + b2 = c2
the hypotenuse side is always the longest so its 28
:
[tex]17 { }^{2} + 20 ^{2} = 28 ^{2} [/tex]
289+ 400 =784
689 = 784
so the triangle is not a right angled triangle

Brandon has a total of 187 postage stamps in his collection.
• he has 48 stamps that are each 14 millimeters wide.
• he has 139 stamps that are each 12 millimeters wide.
what is the total width of the stamps in Brandon's collection?
please help!
Answer:
233.4 Centimeters
Step-by-step explanation:
48 x 10 = 480
48 x 4 = 192
480 + 192 = 672
139 x 10 = 1390
139 x 2 = 272
1390 + 272 = 1662
1662 + 672 = 2334
2334mm = 233.4cm

We are given the equation :
∛(8/729)∛8/∛7292/9Answer:
[tex]\dfrac{2}{9}[/tex]
Step-by-step explanation:
Given expression:
[tex]\sqrt[3]{\dfrac{8}{729}}[/tex]
[tex]\textsf{Apply exponent rule} \quad \sqrt[n]{a}=a^{\frac{1}{n}}:[/tex]
[tex]\implies \left(\dfrac{8}{729}\right)^{\frac{1}{3}}[/tex]
[tex]\textsf{Apply exponent rule} \quad \left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}:[/tex]
[tex]\implies \dfrac{8^{\frac{1}{3}}}{729^{\frac{1}{3}}}[/tex]
Rewrite 8 as (2 · 2 · 2) and rewrite 729 as (9 · 9 · 9):
[tex]\implies \dfrac{(2 \cdot 2 \cdot 2)^{\frac{1}{3}}}{(9 \cdot 9 \cdot 9)^{\frac{1}{3}}}[/tex]
[tex]\implies \dfrac{(2^3)^{\frac{1}{3}}}{(9^3)^{\frac{1}{3}}}[/tex]
[tex]\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}:[/tex]
[tex]\implies \dfrac{2^{(3 \cdot \frac{1}{3})}}{9^{(3 \cdot \frac{1}{3})}}[/tex]
[tex]\implies \dfrac{2^1}{9^1}[/tex]
[tex]\textsf{Apply exponent rule} \quad a^1=a:[/tex]
[tex]\implies \dfrac{2}{9}[/tex]

Answer:
A
Step-by-step explanation:
you just follow the trail
Answer:
A - 2
Step-by-step explanation:
It can't be B or D, because the other triangle is bigger than the first one.
It is not 4 because if you count the squares, you will notice that b=2 and a=4. So the scale factor is 2.

Step-by-step explanation:
0.1 = 1/10
2 ⅒
Answer:
2 1/10
Step-by-step explanation:
To convert the decimal 2.1 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
2.1 = 2.1
--------

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

= (2.1 × 10)
(1 × 10) = 21
------
10
Now you have to simplify, 2 1/10.
