Answer:
<h2>14mph</h2>
Step-by-step explanation:
Given the gas mileage for a certain vehicle modeled by the equation m=−0.05x²+3.5x−49 where x is the speed of the vehicle in mph. In order to determine the speed(s) at which the car gets 9 mpg, we will substitute the value of m = 9 into the modeled equation and calculate x as shown;
m = −0.05x²+3.5x−49
when m= 9
9 = −0.05x²+3.5x−49
−0.05x²+3.5x−49 = 9
0.05x²-3.5x+49 = -9
Multiplying through by 100
5x²+350x−4900 = 900
Dividing through by 5;
x²+70x−980 = 180
x²+70x−980 - 180 = 0
x²+70x−1160 = 0
Using the general formula to get x;
a = 1, b = 70, c = -1160
x = -70±√70²-4(1)(-1160)/2
x = -70±√4900+4640)/2
x = -70±(√4900+4640)/2
x = -70±√9540/2
x = -70±97.7/2
x = -70+97.7/2
x = 27.7/2
x = 13.85mph
x ≈ 14 mph
Hence, the speed(s) at which the car gets 9 mpg to the nearest mph is 14mph
This is a pretty bad question but I think the answer they're looking for is
angle
circle
line segment
We define arcs in terms of circles and parallel lines in terms of lines (though not necessarily line segments, so this is a bit of a judgement call).
Answer:
Al comienzo Juana tiene 28 libras de azúcar.
Ella hace 6 paquetes de 2.5kg cada paquete.
Entonces, entre los 6 paquetes, hay:
6*2.5kg = 15kg de azúcar.
Ahora el problema es que tenemos dos unidades distintas, kilogramos y libras.
Aca podemos usar la relación:
1k = 2.2lb.
Entonces 15kg de azúcar son 15 veces 2.2 libras:
15kg = 15*2.2lb = 33lb.
Esto nos da mas de lo que hay originalmente en el costal.
Ahora si lo pensamos como:
Solo vendió 5 paquetes de 2.5kg, entonces el sobrante queda en el costal inicial:
5*2.5kg = 12.5kg
De vuelta, 1kg = 2.2lb
12.5kg = 12.5*2.2lb = 27.5lb
En este caso hay un sobrante de:
28lb - 27.5lb = 0.5lb
Answer:
$532
Step-by-step explanation:
Ramona worked 2 days which gives you $280 since she gets a flat rate of 140 per day. Then 14% of $600 is 84 and 14% of 1200 is 168 add all of them
