These problems are based on the Pythagorean Theorem. The Pythagorean Theorem is a^2 + b^2 = c^2. If the two sides are equal, the triangle is a right triangle. If c^2 is less, the triangle is acute. If c^2 is more, the triangle is obtuse.

Obtuse: c^2 > a^2 + b^2

Acute: c^2 < a^2 + b^2

Right: c^2 = a^2 + b^2

#7 --- Obtuse

21^2 ___ 8^2 + 15^2

441 ___ 64 + 225

441 > 289

#8 --- Right

20^2 ___ 12^2 + 16^2

400 ___ 144 + 256

400 = 400

#9 --- Acute

6^2 ___ 4^2 + 5^2

36 ___ 16 + 25

36 < 41

Hope this helps!

Olivia and Camille went clothes shopping. Camille spent $19.40 less than twice what Olivia spent. In total, they spent $272.35.
nydimaria [60]

if Camille spent 19.40$ LESS than DOUBLE what Olivia spent then a rough estimate already can be Olivia spent 100 and Camille spent 172 but to find this out we have to add 19.40 onto 272.35 = 291.75 then we now that 291.75 is thrice what Olivia spent so if we third it we know what Olivia spent so 291.75/3 = 97.25 leaving 194.50 then if we minus 19.40 off 194.50 we get 175.10 so:

Camille spent: 175.10 and

Olivia Spent: 97.25

Translate the sentence into an equation.
Andreas93 [3]
<h2>Translating Sentences into Equations</h2>

A key part of this is recognizing certain words to change into operations or numbers:

  • <em>quotient</em> = divide
  • <em>three more</em> = add 3
  • <em>'a/the number' </em>= use a variable (in this case, it's <em>w</em>)

<h2>Solving the Question</h2>

We're given:

  • Three more than the quotient of a number and 7 equals 6
    ⇒ 'the quotient of a number and 7' tells us we divide <em>w</em> by 7:
  • Three more than \dfrac{w}{7} equals 6
    ⇒ 'three more than' means we add 3 to the fraction:
  • \dfrac{w}{7}+3 equals 6
  • \dfrac{w}{7}+3=6

<h2>Answer</h2>

\dfrac{w}{7}+3=6
