The Stuart family has 5 members. They each
purchase a soda at $2.50 each and a hot dog at
$3.50 each. Use mental math to find the total cos
of the food. Justify your answer by using the
Distributive Property.
Answer:
5 (2.50 + 3.50)
The total cost is $30
$12.50 on soda and $17.50
The total cost of all the items for 5 members is $6.00 when the cost of soda is $2.50 and the cost of hot dog is $3.50.
Given that:
Cost of soda = $2.50
Cost of hot dog = $3.50
The total cost of both the items can be calculated by adding the cost of both the items.
Cost of both items = 2.50 +3.50
= $6.00
The cost can also be calculated using distributive property as:
Cost of both items = 2.00+3.00+ 0.50 + 0.50
= $6.00
Thus, the cost of both the items is $6.00.

Answer:
40 goodie bags
Step-by-step explanation:
We know that there are 1000 grams in a 1 kilogram. So the weight of the box with the party goody bags is 6200 grams. To get the weight of just the goody bags, we subtract the weight of the empty box from the box with the goody bags. We have 6200-200=6000 grams. So the weight of all the goody bags is 6000 grams. Since each goody bag is 150 grams, we divide 6000 by 150. So, 6000/150 = 40. Therefore there are 40 goodie bags.

Identify Center Of Dilation and Scale Factor
see image
Answer:
Step-by-step explanation:
A ( 2 , 6 ) ------> A' ( 0 , 2 )
B ( 5 , 3 ) ------> B' ( 1 , 1 )
Equation of the line AA' is y = 2x + 2
Equation of the line BB' is y = ( 1 / 2 ) x + 1 / 2
AA' ∩ BB' = ( - 1 , 0 ) <----- this point is a center of the dilation with the scale 1 / 3
D ( - 4 , - 3 ) -------> D' ( - 2 , - 1 )
C ( 2 , - 3 ) -------> C' ( 0 , - 1 )
The standard diameter of a golf ball is 42. 67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0. 002 mm. Which function could represent this situation? f(x ) = x – |42. 67| f(x ) = |x| – 42. 67 f(x ) = |42. 67 – x| f(x ) = 42. 67 – |x|.
Using function theory, the function that could represent this situation is
f(x) = |42. 67 – x| .
It is given that
The standard diameter of the golf ball = is 42.67
Allowable discrepancy = ±0.002
So upper limit of diameter = 42.672
The lower limit of diameter = 42.668
We need a function that can help in finding a discrepancy.
What is a function?A function is a rule which determines the relation between two variables.
The correct function that could represent this situation will be
f(x ) = |42. 67 – x|
Where x is the diameter of the ball produced.
For example, if a ball of diameter 42.665 is produced
f(x) = |42. 67 – x|
f(42.665) = |42. 67 – 42.670| = 0.005 which is more than the permitted tolerance i.e 0.002.
So, one can easily decide whether to stop production or not.
Therefore, the function that could represent this situation is
f(x) = |42. 67 – x| .

The measures of Angles Y, and Z on the map where, all numbered streets run parallel to each other is 75 and 105 degrees respectively.
What are angles formed by transverse?Angles formed by the transverse line cut by the transversal-
Corresponding angle- Corresponding angle keeps the same position on two different parallel line when cut by transverse.Alternate interior angle- This angle made inside the parallel lines cut by the transversal.Alternate exterior angle- This angle made outside the parallel lines cut by the transversal.Supplementary angle- Angle which made on the same line. The sum of the supplementary angle is equal to the 180 degrees.
In the given map, all numbered streets run parallel to each other. Here, both 3rd and 4th streets are intersected by King Avenue.
Here, the delivery driver is driving around town and has noticed that every time he turns, it creates an angle.
The angle y is the angle whose measure is 75 degree are the corresponding angle. Therefore, they must be equal as,
[tex]m\angle y=75^o[/tex]
Hence, the measure of angle y is 75 degrees.
The angle y angle z are the supplementary angle, made on the same line. Therefore,
[tex]m\angle y+m\angle z=180^o\\75+m\angle z=180\\m\angle z=180-75\\m\angle z=105[/tex]
Hence, the measures of Angles Y, and Z on the map where, all numbered streets run parallel to each other are 75 and 105 degrees respectively.
