What is the opposite of the opposite of -1.4?

sattari [20]

Answer: -1.4

The opposite of -1.4 is 1.4; you flip from negative to positive.

Then taking the opposite of 1.4 gets us back to -1.4 again

Effectively the two opposites cancel out and nothing changes.

You have 10 cups of a cleaning solution that is 10% white vinegar and 90% water. You want the mixture to be 50% white vinegar an

lisabon 2012 [21]

Let
x-->volume of white vinegar you need to add to the mixture (measured in cups)
then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
the volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50multiply both sides by (10+x) and then simplify

(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8

the answer is
you need to add 8 of a cup of the pure vinegar to the mixture

aleksandrvk [35]

Answer:

1st answer is 108

A cone has a volume of 1309cm^3. If the height of the cone is 8 centimeters, find its radius.

zhenek [66]

Answer:

The radius is 12.5.

Step-by-step explanation:

The volume of a cone is found using the formula $V = \frac{1}{3} \pi r^2 h$ . Substitute the values V = 1309 and h = 8. Solve for r.

$V = \frac{1}{3} \pi r^2 h\\1309 = \frac{1}{3} \pi r^2 * 8\\3927 = \pi r^2*8\\156.2 = r^2\\12.5 = r$

Given below are the coordinates of the vertices of a triangle. Find the lengths of the sides of the triangle, then click to iden

Shkiper50 [21]

To find the length of the sides, we use the Pythagorean Theorem. First, let's look at the side RS. R is at (1,3), and S is at (3,1). Therefore, to find RS, we use the difference in height and length: $a = \sqrt{ {b}^{2} + {c}^{2} } \\ a = \sqrt{ {(3 - 1)}^{2} + {(1 - 3)}^{2} } \\ a = \sqrt{ {(2)}^{2} + {( - 2)}^{2} } \\ a = \sqrt{4 + 4} \\ a = \sqrt{8}$
The length of side RS is square root 8.

Side ST is made from point S (3,1) and point T (5,2).
$a = \sqrt{ {(5 - 3)}^{2} + {(2 - 1)}^{2} } \\ a = \sqrt{ {(2)}^{2} + {(1)}^{2} } \\ a = \sqrt{4 + 1} \\ a = \sqrt{5}$
The length of side ST is root 5.

Side RT is between R (1,3) and T (5,2).
$a = \sqrt{ {(1 - 5)}^{2} + {(3 - 2)}^{2} } \\ a = \sqrt{ {( - 4)}^{2} + {(1)}^{2} } \\ a = \sqrt{16 + 1} \\ a = \sqrt{17}$
The side RT is root 17. The triangle is scalene, meaning it has three sides of different lengths.
