Step-by-step explanation:
22 of square foot to the nearest ten is 4.6
Answer:
y = [1]x + [-5 ]
Step-by-step explanation:
the equation is : y = ax+b
the slope is a : a =1 ( same slope parrallal to the line : y= x-3 )
the line that passes through (3, -2) : -2 = (3)+b
b = -5
the equation is : y = x-5
2. $16.90 + $5.99 = $22.89
22.89-5= $17.89 The answer is reasonable
3. 14.85 x 3= $44.55 this is the total cost
to find the tax, multiply 44.55 times 0.2
The answer is not reasonable, the tip should be $8.91
Answer:
Surface area = 505cm²
Step-by-step explanation:
Surface area of the triangular prism. = 2B + ph
B is the base area
p is the perimeter of the triangle
h is the height of the triangle
Base area = 1/2 * base * height
Base area = 1/2 * 18 * 40
Base area = 9 * 40
Base area = 360cm²
Perimeter of the triangle = 41 + 41 + 18
Perimeter of the triangle = 100cm
height of the prism = 45cm
Surface area = 360 + 100 + 45
Surface area = 505cm²
