In a department store the owner paid $15 for 1kg of sugar.The owner marked the price up by 10% for the customers.How much dose h
oee [108]
First, we need to figure out 10% of fifteen.

So, we multiple 15 by 10% (or 0.1 in simpler terms).

That gives us 1.5, which is our mark-up price.

So, finally we add the markup price to the original price to obtain the selling price.

1.5 + 15 = 16.5

The owner charges $16.50 for 1kg of sugar!

(2³)² solve this problem
max2010maxim [7]

Answer:

(2^3)^2 = 64

Step-by-step explanation:

Option 1:

Using the following rule:

(a^n)^m = a^{nm}

Put in our expression,

a = 2

n = 3

m = 2

(a^n)^m = a^{nm}

(2^3)^2 = 2^{3*2}=2^6=64

Option 2:

Using the following rule:

a^n * a^m = a^{n+m}

Since our expression is the same as multiplying 2³ with itself, we can write it as a multiplication.

(2^3)^2 = 2^3 * 2^3

If we compare this with a^n * a^m, we can see that

a = 2

n = 3

m = 3 (in this case, n and m are equal)

a^n*a^m = a^{n+m}

2^3*2^3 = 2^{3+3} = 2^6 = 64

Answer: (2^3)^2 = 64

Enter the equation of the line in slope-intercept form.
likoan [24]

Equation parallel to y = -x is y=-x+k

so 4.5 = -7 + k so k - 11.5

Equation is y = -x + 11.5
