Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

Let P be the decimal value of p percent.

(16000)*(1+P)^2 = 17640

(1+P)^2 = (17640)?(16000)

(1+P)^2 = 1.1025

(1+P) = 1.05

P = 0.05

p = 5.0%

What is the solution to the equation 1/2 (x-12) + 4 = 1/3 (6x-15)?

Answers

Answer:

$x=2$

Step-by-step explanation:

$(1)/(2) (x-12) + 4 = (1)/(3) (6x-15)$

$(x-12)/(y2) +4=(6x-15)/(3)$

$((x-12)+2*4)/(2)=((2*3)x-3*5)/(3)$

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The given parameters are;

Pizza = 16

Proportion of cheese = 2/3

The amount of cheese is the proportion of cheese needed for the flower can be calculated as;

Cheese = Proportion x Pizza

So, we have:

Cheese = 2/3 x 16

Evaluate the product;

Cheese = 32/3

Cheese = 10.6

Hence, 10.6 pounds of cheese is needed for 16 pizzas.

Answer:

Mariana takes the two pills together after 18 hours.

Step-by-step explanation:

Mariana must take two pills; one every 6 hours and another every 9 hours.

She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.

To find the time to take the two pills together, take the least common multiple of 6 and 9.

6 = 2 x 3

9 = 3 x 3

So, the least common multiple is 2 x 3 x 3 = 18

So, she takes the two pills together after 18 hours.

Rewrite each expression by completing the square.
a. z^2 − 5z + 8
b. x^2 + 0.6x + 1

Answers

Answer:

The answer to your question is below

Step-by-step explanation:

z² - 5z + 8

Equal to zero z² - 5z + 8 = 0

Subtract 8 in both sides z² - 5z + 8 - 8 = 0 - 8

Simplify z² - 5z = -8

Divide -5 by 2 write the result

in both sides of the equation z² - 5z + (-5/2)² = -8 + (-5/2)²

to the power of 2

Simplify z² - 5z + 25/4 = -8 + 25/4

z² - 5z + 25/4 = -32/4 + 25/4

z² - 5z + 25/4 = -7/4

Factor (z - 5/2)² = -7/4

x² - 0.6x + 1

Convert 0.6 to a fraction 0.6 = 6/10 = 3/5

x² - 3/5x + 1

Equal to zero x² - 3/5x + 1 = 0

Subtract -1 in both sides z² - 3/5z + 1 - 1 = 0 - 1

Simplify z² - 3/5z = - 1

Divide -3/5 by 2 write the result

in both sides of the equation z² - 3/5z + (-3/10)² = -1 + (-3/10)²

to the power of 2

Simplify z² - 3/5z + 9/100 = -1 + 9/100

z² - 3/5z + 9/100 = -100/100 + 9/100

z² - 3/5z + 9/100 = -91/100

Factor (z - 3/10)² = -91/100
