Answers:
1. The n-intercept is 12. That means after 12 visits the amount of money on the gift car is $0.
2. The A(n)-intercept is 150. Before the visits, the amount of money on the gift car is $150.
Solution:
Amount of money on the gift card after n number of visits: A(n)=$150-$12.50 n
A(n)=150-12.50 n
1. n-intercept
A(n)=0→150-12.50 n =0
Solving for n: Subtracting 150 both sides of the equation:
150-12.50 n-150 = 0-150
-12.50 n = -150
Dividing both sides of the equation by -12.50:
(-12.50 n) / (-12.50) = (-150) / (-12.50)
n=12
The n-intercept is n=12; for n=12→A(12)=0. Point (n, A(n))=(12,0)
2. A(n) intercept
n=0→A(0)=150-12.50 (0)
A(0)=150-0
A(0)=150
The A(n) intercept is 150; for n=0→A(0)=150. Point (n, A(n))=(0,150)
40 because 180-60=120 and 120 divided by 3 is 40.
A protons and electrons is the correct one
Answer: 68 mL
Step 1: Write volume formula
The formula for volume is often abbreviated into V=l×w×h. This stands for volume= length×width×height.
Step 2: Substitute numbers for answer in cm
To get the answer in cm, simply substitute the numbers into the equation. Then, you may simply multiple them to solve.
V=4.0 cm×8.5 cm×2.0 cm
V= 68 cm
Step 3: Add cubed symbol
Since this is referring to volume, you will need to add the cubed symbol to the end of your answer. This will appear as a number 3 above the cm on the right side.
Step 4: Convert to mL
This is a simple step once you understand the formula to convert. Luckily for us, cm cubed (cm3)= 1 mL. Because of this, the answer will remain as 68 mL
Hope this is right and it helps you!
Answer:
x = 535
Step-by-step explanation:
x/30 - 1/6 = 18
6x - 30/180 = 18
6x - 30 = 18 × 180
6x = 3240 - 30
6x = 3210
x = 3210/6
<em><u>x = 535</u></em>
