Answer:
A = 27π cm² or about 84.8 cm²
Step-by-step explanation:
Area of a full circle is πR²
As there are four right angles making up a 360° turn, and the missing piece is one of those four, there are ¾ of a circle remaing
A = ¾πR² = ¾π6² = 27π cm² or about 84.8 cm²
The car goes 23.2 miles every gallon, so with 15 gallons (15 * 23.2 = 348) it can go 348 miles. With the extra .25 that the car has, it can go 0.25 * 23.2 = 5.8 miles. 348 miles plus the 5.8 miles gets you 353.8 miles on 15.25 gallons.
Answer:
f(-3) = 21
g(3) = 69
Step-by-step explanation:
We have been given the following functions;
f(x) = –6x + 3
g(x) = 3x + 21x–3.
To find f(-3) , we simply substitute x = -3 in the function of f(x);
f(-3) = -6(-3) + 3
= 21
To find g(3) , substitute x = 3 in the function of g(x);
g(3) = 3(3) +21(3) - 3
= 69
Answer:
$1,006.40
Step-by-step explanation:
Basic week = ($14.80/hour) * (40 hours) = $592.00
M-F overtime = ($14.80/hour ) * ( 1.25 ) * (12 hours) = $222.00
Sat overtime = ($14.80/hour ) * ( 1.5 ) * (2 hours) = $44.40
Sun overtime = ($14.80/hour) * ( 2 ) * (5 hours) = $148.00
Total wage = 592.00 + 222.00 + 44.40 + 148
Total wage = $1,006.40
Answer:
f(3) = -13
Step-by-step explanation:
f(x)= - x²-4 (not (-x)²)
f(3) = - 3² - 4 = - 9 - 4 = -13
