Answer:
Step-by-step explanation:
% = Red / (Blue + red ) * 100
% = 75/(125 + 75) * 100
% = 75 / 200 * 100
% = 7500 / 200 = 37.5% are blue
Answer:
a) 1.28
b) 2.57*10^-7 mg²
c) 8.14*10^7 dm
d) 3.79 m/s
e) 9.78*10^-3 mg
Step-by-step explanation:
a) 7.31 / 5.7 = 1.28, km/km is the same unit, so they cancel each other out. The answer is 1.28 without unit.
b) (3.26*10^-3) * (7.88*10^-5) = 2.57*10^-7 mg², here, mg * mg, this is mg²
c) (4.02*10^6) + (7.74*10^7) = 8.14*10^7 dm, here, the unit are added together, so we maintain it
d) (7.8 - 0.34) m / (1.15 + 0.82) m = 7.46 m / 1.97 m = 3.79 m/s, here, the numerator has the unit of m, and the denominator has the unit of s. Giving us m/s.
e) (9.88*10^-3) - (9.66*10^-5) = 9.78*10^-3 mg. Here, the unit was subtracted from each other, so we maintain it.
Answer:
$461
Step-by-step explanation:
First, find the cost with the daily charge of $29.
Multiply 14 by 29, since the car was rented for 14 days:
14(29)
= 406
Find the cost with the distance traveled. Since there is only a charge after the first 100 km, subtract 100 from 320.
320 - 100
= 220
Find the charge by multiplying this by 0.25:
220(0.25)
= 55
Add this to the daily charge:
55 + 406
= 461
So, the cost will be $461

Answer:
Step-by-step explanation:
Given expression:
Let u = (x - y):
To factor a quadratic in the form 
find two numbers that multiply to 
and sum to 
:
Therefore, the numbers are: -6 and -4.
Rewrite as the sum of these two numbers:
Factor the first two terms and the last two terms separately:
Factor out the common term (u - 2):
Substitute back in u = (x - y):
Simplify:
