Answer:
Step-by-step explanation:
First calculate the amount of notebooks and textbook
Cost of 2 notebooks = 2 *8.75
= $ 17.5
Cost of 1 textbook = $ 74.95
Total cost = 17.5 + 74.95
= $ 92.45
Tax = 7% of total cost
= 0.07 * 92.45
= $ 6.47
Total cost = 92.45 +6.47
= $ 98.92

Answer:
√13
Step-by-step explanation:
There's a formula called the distance formula that is based on the Pythagorean theorem. It is used to find the distance between points in 2 (or more) dimensions.
The distance (d) between points (x1, y1) and (x2, y2) is ...
d = √((x2-x1)^2 +(y2-y1)^2)
___
To find the distance you're looking for, fill in the values in the formula and do the arithmetic.
d = √((6-3)^2 +(5-7)^2) = √(3^2 +(-2)^2)
d = √(9 +4)
d = √13
The distance between the given points is √13.
Answer:
(3z+15) cm
Step-by-step explanation:
Perimeter: z cm + 8 cm + (z+3) cm + (z+4) cm = z cm + (z+3) cm + (z+4) cm +8 cm = (3z + 7) cm + 8 cm = (3z+15) cm.
