Answer:
7 months
Step-by-step explanation:
To find the amount the gym memberships will be the same, write a system of equations and find their intersection point. The intersection point will be the two equations equal to each other.
Gym 1 charges a one time joining fee of $245 and then adds to that $40 a month or 40m. So together the cost is 245 + 40m.
Gym 2 charges $0 or no joining fee. Then adds $75 per month or 75m.
So to find when they are equal, then 75m = 245 + 40m. Solve for m.
75m = 245 + 40m
35m = 245
m = 7
Answer:
total mass of 6 samples = 538.896 g
in terms of X = 5.283 g
Step-by-step explanation:
Given:
Number of crude oil samples = 6
Density of each sample = 0.8240 kg/L
Volume filled by each sample = 1.09 × 10⁻⁴ m³
now,
1 m³ = 1000 L
thus,
1.09 × 10⁻⁴ m³ = 1.09 × 10⁻⁴ m³ × 1000 = 0.109 L
also,
Mass = Density × Volume
or
Mass of each sample = 0.8240 × 0.109 = 0.089816 kg
Thus,
total mass of 6 samples = Mass of each sample × 6
or
total mass of 6 samples = 0.089816 kg × 6 = 0.538896 kg
or
total mass of 6 samples = 538.896 g
or
in X =
= 5.283 g
X=20x25 notebooks, y=12x20 notebooks = x/2
x/2 + x = 48 => 3/2*x = 48 and x = 32, so 32 of 20x25 and 16 of 12x20.
Does it make sense? I think you will solve the next one yourself! :)
I will assume that "C=600 cm" refers to the radius of the given circle. Clearly, mABC refers to the length of arc ABC and is 75 cm.
The formula for arc length is s=r(angle in radians).
Here s=75 cm and r=600 cm. Thus, (angle in radians) = s/r, or
(angle) = 75 cm / 600 cm = 0.125 radian.
We must convert this to degrees.
0.125 radian * (180 degrees)/(3.14 rad) = 7.17 degrees = <ADC
