Answer:
13 1/2
Step-by-step explanation:
this is surely the answer. 13.5
The shape at the top is a trapezoid with width 2 cm and lengths 4 and 8 cm.
Its area is
4+8
-------- 2 cm = 12 cm^2
2
The lower part consists of two congruent triangles. The area of a triangle is
A = (1/2)(b)(h). Here, A = (1/2) (4)(5.75) = 11.5, so the area of both triangles is 23 cm^2.
Thus, the total area is (12+23) cm^2, or 35 cm^2.
Answer:
each pencil costs $0.52 before sales tax was added
Explanation:
Assume that the price of each pencil before sales tax is x.
The total amount that Alliya paid can be computed as follows:
Total payment = x*number of pencils + sales tax
We are given that:
Total payment = <span>$6.70
</span>number of pencils = 12 pencils
sales tax = <span>$0.46
Substitute with the givens in the above equation and solve for the price of each pencil (x) as follows:
</span>Total payment = x*number of pencils + sales tax
6.70 = x * 12 + 0.46
6.7 - 0.46 = 12x
6.24 = 12x
x = 6.24/12
x = $0.52
Hope this helps :)
