Associative Property states that grouping symbols does not affect the outcome. This property works for Addition and Multiplication:

2 + (3 + 4) = (2 + 3) + 4

6 • (5 • 4) = (6 • 5) • 4

The associative property is a property of some binary operations. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.

Martin's neighbors pay him $8 per week to walk their dog. He saves his money for 5 weeks. Martin buys a new bike helmet for $37.

KIM [24]

Answer:

Step-by-step explanation:

Martin get's $8 EVERY WEEK

So, in 5 weeks, he will get:

8 * 5 = $40

He saves up all the 5 weeks, so he has all the money.

After 5 weeks, he has:

$40

Answer:

Length of each side of the square = 8 cm

Step-by-step explanation:

In the figure attached, diagrams of a right triangle and a square have been given.

"Area of the square is twice the area of the triangle."

Let one side of the square = x cm

Therefore, area of the square = x²

Area of the given triangle = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(16)(4)$

= 32 cm²

Therefore, x² = 2 × 32

x² = 64

x = 8 cm

Therefore, length of each side of the square will be 8 cm.

Bert didn't finish 1/8 of the problems on a math test he made Mistakes on 1/6 of the problems the rest he answered correctly wha

Viefleur [7K]

Answer:

The fraction of the problems did he answer correctly is $(\frac{35}{48})$

Step-by-step explanation:

Here, let us assume the total number of problems in the test = p

Now, Bert did not finish 1/8 of the problems.

⇒The number of unfinished problems by Bert = $\frac{1}{8} \times p= \frac{p}{8}$

Also, the number of finished problems

= Total problems - Unfinished problems

$= p - \frac{p}{8} = \frac{7p}{8}$

Now, again 1/6 of the total finished problems had mistakes.

So, the number of problems with mistakes = $\frac{1}{6} \times \frac{7p}{8} = \frac{7p}{48}$

The total answers did correctly

= Total answers done - Problem with mistakes

$= \frac{7p}{8} - \frac{7p}{48} = \frac{(42 - 7)p}{48} = \frac{35}{48}p$

Hence, the fraction of the problems did he answer correctly is $(\frac{35}{48})$
