Answer:
$12.00
Step-by-step explanation:
To find the sales tax, we take the price and multiply by the tax rate
tax = price * tax rate
.72 = price * 6%
Changing the percent to a decimal
.72 = price *.06
Dividing each side by .06
.72/.06 = price*.06/.06
12 = price
The price is $12.00
Answer:
u * v = 39 ⇒ 2nd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- u and v are two vectors
- u * v means the scalar product of the two vectors
- The scalar product is a way of multiplying vectors
- The result of a scalar product is always a number not a vector
- Ex: If u = ai + bj ⇒ <a , b> and v = ci + dj ⇒ <c , d> then the scalar
product of them is ac + bd where ac + bd is a number
* Lets solve the problem
∵ Vector u = 13j ⇒ <0 , 13>
∵ Vector v = i + 3j ⇒ <1 , 3>
- Lets find the scalar product
∴ u * v = (0)(1) + (13)(3)
∴ u * v = 0 + 39
∴ u * v = 39
Answer:
x=1
Step-by-step explanation:
3(x+2)-10=4x-6+x
3x+6-10=5x-6
3x-5x-4=-6
-2x-4=-6
-2x=-6+4
-2x=-2
2x=2
x=2/2
x=1
Change the Whole Number to a fraction, or just plug it in a claculator 7-(4/24)= 6.8333333333.
if you change the whole number to a fraction you would have to multiply 7 by 24 to have a common denominator which would give you 168/24 so
168◽4◽164.▫▫▫
➖ --- ➖ = ➖ ◽◽◽
24◽24 ◽24.◽◽◽

Irrational, because there is no number multiplied by itself that will have an answer of 127
