Answer:
$25.80
Step-by-step explanation:
First find the price of the meal with sales tax. Multiply 6.75% by $72.50.
72.50 * 0.0675 = 4.89
Add this value onto 72.50.
72.50 + 4.89 = 77.39
Divide this amount by 3.
77.39 / 3 = 25.7966...
Round this to the nearest hundredth because we're dealing with money.
$25.80 is how much each person should pay.
ANSWER: square root of 10
Rule: Pythagorean Theorem (a^2 + b^2 = c^2; side^2 + second side^2 = hypotenuse^2)
(substitute the missing side w/ a variable)
x^2 + 7^2 = (sqrt. 59)^2
x^2 + 49 = 59
x^2 = 10
x = sqrt. 10
Answer: 6
Step-by-step explanation:
Answer:
144 ft^2
Step-by-step explanation:
Back (vertical): (4 ft)(8 ft) = 32 ft^2
Right side (vert.): (4 ft)(6 ft) = 24 ft^2
Front (vert.): (4 ft)(10 ft) = 40 ft^2
Top (horizontal): A = (1/2)(6 ft)(8 ft) = 48 ft^2 total (top and bottom)
Total surface area is (32 + 24 + 40 + 48) ft^2, or 144 ft^2
