Answer:
sorry dont know
Step-by-step explanation:
To get the perimeter of the trapezoid, we will add the lengths of the 4 sides together.
So, first we will need to get the length of each side.
Base of trapezoid = 8 - 2 = 4 unitsThe upper edge of the trapezoid = 6 - 4 = 2 unitsNow, for the two side edges, we can note that
they are both equal. So, we need to get only one length (as the other would be the same). I will get the length of the left side.
Coordinates of the start point are (2,4) which represent (x1,y1)
Coordinates of the end point are (4,9) which represent (x2,y2)
To get the distance between the two points, we will use the rule attached in the image below as follows:
distance = sqrt ((4-2)^2+(9-4)^2)
distance = √29
Therefore, each of the side edges equal √29 unitsFrom the above, we can now easily get the perimeter as follows:perimeter = 6 + 2 + √29 + √29
perimeter = 8 + 2√29 units
Based on the above calculations, the best choice would be:D. 8 + 2√29 units
Answer:
12
Step-by-step explanation:
Answer:
(a) C = 0.29<em>t</em> + 2.50
(b) 5
Step-by-step explanation:
The variables are defined as follows:
<em>t</em> = the number of toppings
<em>C</em> = total cost for ice cream
It is provided that:
- An ice cream with no toppings is $2.50.
- Every topping is priced at $0.29 each.
(a)
The algebraic equation to find the total cost for ice cream depending on the number of toppings is:
C = 0.29<em>t</em> + 2.50
(b)
Compute the number of toppings Mr. Torrance can buy if he wants to spend only $4.00 on it as follows:
C = 0.29<em>t</em> + 2.50
4.00 = 0.29<em>t</em> + 2.50
0.29<em>t</em> = 4.00 - 2.50
0.29<em>t</em> = 1.50
<em>t</em> = 5.1724
<em>t</em> ≈ 5
Thus, Mr. Torrance can buy 5 toppings.
