The price of a visit to the dentist is $50. If the dentist fills any cavities, an additional charge of $100 per cavity
gets added to the bill.
If the dentist finds n cavities, what will the cost of the visit be?
Answer:
I believe the answer will be 50+100n dollars
Step-by-step explanation:
n is the number of cavities so however many cavities there is, it gets multiplied by 100, in this case, it is 100*n which is 100n. So your final cost would be 50+100n dollars.

Given the diagram below, find the height of the shorter tree.
16.2 m
7 m
13 m
19.7 m
Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{h}{39}[/tex] = [tex]\frac{16}{48}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )
3h = 39 ( divide noth sides by 3 )
h = 13
300$ at 6% for 2 yrs what is the simple interest
Answer:
Simple interest after 2 year = $36
Step-by-step explanation:
Given:
Amount invested = $300
Number of year amount invested = 2 year
Rate of interest per year = 6% = 6/100 = 0.06
Find:
Simple interest after 2 year
Computation:
Simple interest formula;
Simple interest = [Amount invested][Rate of interest][Number of year]
Simple interest after 2 year = [300][0.06][2]
Simple interest after 2 year = [18][2]
Simple interest after 2 year = $36

The difference between two numbers is 10 and their sum is 20. Find the biggest number.
Answer:
15
Step-by-step explanation:
x - y = 10, then x = 10 + y
x + y = 20
substitute for x:
10 + y + y = 20
2y = 10
y = 5
x = 10 + 5 = 15

Answer:
x + 2y = -2
Step-by-step explanation:
Well let's examine the relation between x and y in a perpendicular line.
We can use the fact that for a line Ax + By = C, any line with equation Bx + (-A)y = D is perpendicular (swapping A and B gives a mirror image with respect to the line x=y and changing one of the signs gives a mirror image with respect to axis x or y. Those two together give a perpendicular line).
So we're looking for a line with equation x + 2y = D
We know what it passes through the point (6, -4), so let's input it into the equation x + 2y = D
6 + 2*(-4) = D
6 - 8 = D
D = -2
So the equation is x + 2y = -2
note that 2x + 4y = -4
or any other multiple also works.

Given that sin θ= 1 / √2, we want to find the value of tan θ.
First, find the value of θ.
Answer:
value of tan θ = 1
Step-by-step explanation:
To find θ do the asin of 1/√2
θ = asin (1/√2)
θ = asin (0.707106781)
θ = 45
and then to find tan θ, do tan 45
tan 45 = 1

What is the amount of interest that Sam will pay on his $5000 loan if his monthly payment for three years is 150
Answer:
Amount of interest pay by Sam = $400
Step-by-step explanation:
Given:
Amount of loan taken by Sam = $5,000
Monthly payment made by Sam = $150
Number of year payment made by Sam = 3 Year
Find:
Amount of interest pay by Sam
Computation:
Total amount pay by Sam in 3 year = Monthly payment made by Sam x 12 x 3
Total amount pay by Sam in 3 year = 150 x 12 x 3
Total amount pay by Sam in 3 year = $5,400
Amount of interest pay by Sam = Total amount pay by Sam in 3 year - Amount of loan taken by Sam
Amount of interest pay by Sam = $5,400 - $5,000
Amount of interest pay by Sam = $400
