Jeannie wants to buy her llama a sweater for $32. It's on sale for 20% off. Sales tax is 6.75%. What is the final cost?

Answer:

10 i believe

Step-by-step explanation:

Answer:

C = 5pi inches or approximately 15.7 inches

Step-by-step explanation:

The circumference of a circle is given by

C = pi *d

The diameter is given by d=5

C = pi *5

If we use pi is approximated by 3.14

C = 3.14 *5 =15.7

C = 5pi inches or approximately 15.7 inches

Answer:

shen's new area will be 1200 ft ^ 2

It will be 2 times the original

Donna should increase the length by 5 times

Step-by-step explanation:

Original length = 40

New length = 30 x 4 = 120

Original width = 20

New width = 20 x 5 = 100

120 x 100 = 12000 ft^2

12000/600 = 20

It will be 20 times larger

For Donna:

ex:

length = 1

width = 2

Area = 2

He wants it to be 15 times 2

Lisa says increase 4 times

2 x 3 = 6

30/6 = 5

Answer: no

Step-by-step explanation:

if diego car can hold 14 gallons and eveery day they use 0.6 0.6x25 is 15 which means that they can drive 15 days in all so 15-1.5 13.5 so they can only drive for 13.5 days

hope this helps :)

Answer:

No, Diego's family cannot drive the car for 25 days without the warning light coming on.

Step-by-step explanation:

Find how much fuel they will use in 25 days by multiplying 25 by 0.6, since the car uses 0.6 gallons each day:

25(0.6)

= 15

Subtract this from 14 to see how much fuel will remain, starting from a full tank:

14 - 15

= -1

The number is negative, meaning that driving the car for 25 days will use up all of the fuel. So, the warning light will come on.

No, Diego's family cannot drive the car for 25 days without the warning light coming on.

Answer:

Step-by-step explanation:

I'll focus on -10v^2=-810 and will aim to find the solution, v.  Dividing both sides by -10, we get v^2 = 81, so that v = ±9 (two roots).

The other equation, 7r^2 = -70, has no real solutions.

r^2 = -70 yields r = ±i√10 (two imaginary solutions)

Answer:

112

Step-by-step explanation:

Expected Value is anticipated value, calculated by multiplying each of possible outcomes with their probability of occurrence.

If Price has = 60% chance of value 120 , & 40% chance of value 100

Expected Value = Sum ( Probability of outcome x Payoff )

E (X) = Σ [ xi . PR ( xi ) ] =  x1. Pr (x1) + x2 . Pr (x2)

= 0.6 (120) + 0.4 (100) = 72 + 40

= 112

Answer: B not sure if I’m right though .

Step-by-step explanation:

Answer:

10*3=5(x-4)(doing cross multiplication)

30=5x-20

30-20=5x

10/5=x

2=x

Step-by-step explanation:

Answer:

x=10 so the proportion is 3/6 =5/10

Step-by-step explanation:

5(x-4) = 3*10, cross multiply

5x -20 =30, distribute in parenthesis

5x = 30 +20, add 20 on both sides

5x=50, combine like terms

x= 10, divide both sides by 5

Answer:

C.  69°

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

Answer:

[tex]pH = 13[/tex] --- Oven Cleaner

[tex]pH = 6.2[/tex] --- Water

[tex]pH =7.4[/tex] --- Blood

[tex]pH = 2.2[/tex] --- Vinegar

Step-by-step explanation:

The given molar concentration are:[Missing from the question]

Oven Cleaner: [h+] = [tex]10^{-13}[/tex]

Water: [h+] = [tex]0.0000007[/tex]

Blood: [h+] = [tex]0.00000004[/tex]

Vinegar: [h+] = [tex]0.0063[/tex]

Required

Determine the pH

pH is calculated using:

[tex]pH = -\log(h+)[/tex]

So, we have:

Oven Cleaner:

[tex]pH = -\log(10^{-13})[/tex]

Using a calculator, we have:

[tex]pH = 13[/tex]

Water:

[tex]pH = -\log(0.0000007)[/tex]

Using a calculator, we have:

[tex]pH = -1*-6.2[/tex]

[tex]pH = 6.2[/tex]

Blood:

[tex]pH = -\log(0.00000004)[/tex]

Using a calculator, we have:

[tex]pH = -1 * -7.4[/tex]

[tex]pH =7.4[/tex]

Vinegar:

[tex]pH = -\log(0.0063 )[/tex]

Using a calculator, we have:

[tex]pH = -1 * -2.2[/tex]

[tex]pH = 2.2[/tex]

Answer:

The radius is 4 units, and the equation of the circle is:

(x - 3)^2 + (y + 5)^2 = 16

Step-by-step explanation:

A circle centered at the point (a, b) and with a radius R, is written as:

(x - a)^2 + (y - b)^2 = R^2

In the image, we can see that a segment that cuts the circle in two halves is the segment between the points:

(-1, -5) and (7, - 5)

The distance between these points is the diameter of the circle.

Remember that the distance between two points (x₁, y₁) and (x₂, y₂) is:

D = √( (x₂ - x₁)^2 + (y₂ - y₁)^2)

Then in this case, the distance between the known points is:

D = √( (7 - (-1))^2 + (-5 - (-5))^2)

D = √( 8^2) = 8

The diameter of the circle is 8

Then the radius is:

R = 8/2 = 4

the radius is 4.

Now, to find the center of the circle we just need to go to any of the two extremes of the interval and count 4 units towards the center of the circle, this is:

(-1 + 4, -5) = (3, -5)

or

(7 - 4, -5) = (3, -5)

Then the center of the circle is the point (3, -5) and the radius is R = 4

The equation of the circle is:

(x - 3)^2 + (y - (-5))^2 = 4^2

(x - 3)^2 + (y + 5)^2 = 16
