Explanation;
Sales tax is computed as the product of the price times the tax rate in % divided by 100:
- Sales tax = price × tax rate / 100
Here is each compute:
- $299 × 4% = $299 × 4/100 = $11.96
- $6,750 × 7% = $6,750 × 7/100 = $ 472.50
- $76.50 × 5.2% = $76.50 × 5.2/100 = $3.98
- $18.32 × 3.9% = $18.32 × 3.9/100 = $0.71
- $5.95 × 6.2% = $5.95 × 6.2/100 = $0.37
- $13.89 × 4.3% = $13.89 × 4.3/100 = $0.60
- $768.43 × 3.7% = $768.43 × 3.7/100 = $28.43
- $6.49 × 5.8% = $6.49 × 5.8/100 = $0.38
- $23.86 × 7.1% = $23.86 × 7.1/100 = $1.69
Answer:
c = 
f= 1500
Step-by-step explanation:
Tenemos la siguiente ecuación
Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

Si restamos la segunda ecuación de la primera, tenemos que

Luego

Entonces 
Si tomamos la primera ecuación, tenemos que
. Es decir,

Esta solución, al plantear 2 ecuaciones y dos incógnitas, plantea un sistema dos por dos.
Answer:
5 un^2
Step-by-step explanation:
the liens from (0, 0) to (1, 3) and (1, 3) to (4, 2) are perpendicular meaning that the angle at (1, 3) is a right angle
to find the lengths of the sides we must use the pythagorean theorem
a^2 + b^2 = c^2
for the leftmost side
we have 1^2 + 3^2 = c^2
1 + 9 = 10
c^2 = 10
c = sqrt(10)
for the top side
we have
the same thing
1^2 + 3^2 = c^2
1 + 9 = 10
c^2 = 10
c = sqrt(10)
you must multiple sqrt(10) by sqrt(10) and then by 1/2
sqrt(10) * sqrt(10) is 10
10 * 1/2 is 5
the area is 5 un^2
-5 x b =-35
I’ve done this in school before my teacher told us that was the answer so
