Mr. Stein is purchasing a 2.25 pounds of meat that cost $2.80 per pound. How much will he receive if he pays the cashier $20.00

1 answer:

4 0

He will receive $13.70.

You would have to multiply 2.25 by 2.80 to get 6.30, which is the total cost due. Subtract 6.30 from 20 to get your answer, 13.70, or the change Mr. Stein will receive.

bezimeni [28]

Answer:

Step-by-step explanation:

<em>Midpoint Formula:</em>

$\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}$

$\frac{3+1}{2}$ ⇒ $\frac{4}{2}$ ⇒ $2$

$\frac{8+-4}{2}$ ⇒ $\frac{8-4}{2}$ ⇒ $\frac{4}{2}$ ⇒ $2$

Find all points having an x-coordinate of 5 whose distance from the point (2, 6) is 5

galina1969 [7]

Answer:

(5,2) and (5,10)

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$points\ (2,6),(5,y)\\d=5$

substitute in the formula

$5=\sqrt{(y-6)^{2}+(5-2)^{2}}$

solve for y

$5=\sqrt{(y-6)^{2}+(3)^{2}}$

$5=\sqrt{(y-6)^{2}+9}$

square both sides

$25=(y-6)^{2}+9$

$(y-6)^{2}=25-9$

$(y-6)^{2}=16$

square root both sides

$y-6=\pm4$

$y=6\pm4$

$y=6+4=10$

$y=6-4=2$

therefore

The points are

(5,2) and (5,10)

andrezito [222]

Answer:

18 hours

Step-by-step explanation:

There are 24 hours in a day and we have 5 weekdays per week.

15% of 24 hours

15/100×24

0.15×24

=3.6 hours

Mrs Miller spends 3.6 hours of each weekday traveling in her car.

There are 5 weekdays in a week to include: Monday, Tuesday, Wednesday, Thursday and Friday.

If she spends 3.6 hours per weekday

Then,

During the week, she will spend

3.6 hours× 5 weekdays

=18 hours

She will spend 18 hours per week traveling in her car.

The rational expression that results into x-4/2(x+4) is<em> x²-16/2x+8 * x+4/x²+8x+16</em>

<h3>Multiplying rational expressions</h3>

Rational expressions are written in the form a/b where a and b are integers.

According to the question, we need to determine the expression that is equal to x-4/2(x+4)

From the fourth option;

x²-16/2x+8 * x+4/x²+8x+16

Factorize the quadratic part to have;

x²-16/2x+8 * x²+8x+16/x+4

(x+4)(x-4)/2(x+4) * x+4/(x+4)^2

Cancel out the common expression to have;

x-4 * 1/2(x+4)

x-4/2(x+4)

Hence the rational expression that results into x-4/2(x+4) is<em> x²-16/2x+8 * x+4/x²+8x+16</em>
