To group an expression, means that the factors of the expression are to be separated in (), [] or {}.

An expression with a value of 80 is: 2^2 \times ( [2 + 2] \times [3 + 2] )

The number is given as:

80

Factorize

80 = 2 \times 40

Factorize 40

80 = 2 \times 2 \times 20

Express 2 \times 2 as an exponent

80 = 2^2 \times 20

Express 20 as 4 x 5

80 = 2^2 \times ( 4 \times 5)

Express 5 as 3 + 2

80 = 2^2 \times ( 4 \times [3 + 2] )

Express 4 as 2 + 2

80 = 2^2 \times ( [2 + 2] \times [3 + 2] )

Hence, the above expression has a numerical value of 80

The Rodriguez family went to dinner at at Pasta Palace. Mr. Rodriguez ordered a meal for $6.25; Mrs. R ordered a meal for $7.50;
lidiya [134]
Cost of the meal ordered by Mr. Rodriguez = $6.25
Cost of the meal ordered by Mrs. Rodriguez = $7.50
Cost of each pizza ordered by the two children = $4.99
Then
The cost of the 2 pizzas ordered by the 2 children = (2 * 4.99) dollars
                                                                                 = 9.98 dollars
So
The total cost of the orders = (6.25 + 7.50 + 9.98) dollars
                                             = 23.73 dollars
Percentage of tip on the bill = 15%
Then
Amount of tip paid = (15/100) * 23.73 dollars
                              = 355.95/100 dollars
                              = 3.56 dollars
Percentage of tax paid on the bill = 7.25%
Amount of sales tax that was paid = (7.25/100) * 23.73 dollars
                                                       = 172.04/100 dollars
                                                       = 1.72 dollars
So
The total bill that was paid = (23.73 + 3.56 + 1.72) dollars
                                           = 29.01 dollars

YM is a median of the triangle below. XM = 2x + 2 and ZM = 4x - 8. What 5 points
LenaWriter [7]

Answer:

Option A: 12

Step-by-step explanation:

From the image of the triangle given, we can see that:

XM = ZM

We are given that:

XM = 2x + 2 and ZM = 4x - 8

Thus;

2x + 2 = 4x - 8

Rearrange to get;

4x - 2x = 8 + 2

2x = 10

x = 10/2

x = 5

Thus, XM = 2(5) + 2

XM = 12

1001112 = [ ? ]10<br> ?<br> what number belongs where the question mark is
EleoNora [17]

I suppose you're supposed to convert 100111 from base 2 to base 10. We have

100111_2=2^5+2^2+2^1+2^0=32+4+2+1=39_{10}

so the missing number is 39.

Answer:

1. 9 pi, 2. 121 pi

Step-by-step explanation:

The formula for circumference is pi d. So for the first question the radius would be three. The you do pi r ^2 for area so 3 times pi squared. Which is 9 pi. For the second you will do the same thing you will do 22 pi divided by 2 which is 11 pi then you will square 11pi and get 121 pi
