MakcuM [25]3 years ago
3 0

Answer:

The expression that belongs in the box is 8 x 4

Option C is correct answer.

Step-by-step explanation:

We need to find Which expression belongs in the box?

(3 \times 8)  \times 4= 3 \times (------)

The property applied here is associative property of multiplication.

Associative property of multiplication states that:

(a \times b)\times c = a \times (b \times c)

So, if we apply the property to our question we have:

a = 3

b = 8

c = 4

So, the expression will become: (3 \times 8)  \times 4= 3 \times (8 \times 4)

So, the expression that belongs in the box is 8 x 4

Option C is correct answer.

Miss Hoffman gave 90-cent tip to a waitress for serving a meal costing $6.00 what percent of the bill is her tip?
seraphim [82]
So,

Miss Hoffman gave 90 cents to the waitress.

Her meal, including the tip, cost $6, or 600 cents.

Her subtotal was represented by the quantity (600 - 90) cents.
600 - 90 = 510

Dividing 90 by 510 yields the percent tip that Miss Hoffman gave the waitress.
\frac{90}{510}
\frac{9}{51}
0.176 or 17.6% ≈ 18%

Miss Hoffman gave the waitress approximately 18% tip.

Answer:

Following the rules the coordinate pairs are: (1,0), (5,1), (17,3), (53,7), (161,15)

Step-by-step explanation:

Nicole's Pattern: Multiply by 3 then add 2, starting from 1

Ion's Pattern: Add 1/2 then multiply by 2 starting from 0

So, Nicole's pattern is generated starting from 1, we multiply by 3 and then add 2 to get the next number

While Ion's pattern is generated starting from 0, we add 1/2 to it and then multiply by 2 to get the next number

Nicole's Pattern               Ion's Pattern          Coordinate pairs

1                                          0                               (1,0)

5                                          1                                (5,1)

17                                         3                              (17,3)

53                                        7                               (53,7)

161                                        15                              (161,15)
