63 1/3% of 60 is what

1 answer:

5 0

As a general rule, a percentage can be converted to a decimal fraction by dividing the given percentage by 100%.

63 1/3% is equivalent to 190/3% . Dividing this by 100%, we get 190/300, or 19/30.

63 1/3% of 60 is what? To determine this, multiply 60 by 19/30. That comes out to (60)(19)/30, or 2(19), or 38 (answer).

Sean made a ribbon that was 3 1/6 inches long. Fran made one that was 1 5/6 inches long.How much longer was Sean's ribbon than F

brilliants [131]

Let's rewrite the mathematical expressions:
3 1/6 = 3.166666667
1 5/6 = 1.833333333
Subtracting both expressions we have:
3.166666667- 1.833333333 = 1.727272727
Answer:
Sean's ribbon is 1.727272727 in long than Fran's

Given an equilateral triangle with two vertices located at (-8, -5) and (3, 7), what is its perimeter?

Oduvanchick [21]

An equilateral triangle has 3 sides of equal length
find the length of 1 side and that is the length of te other 2 sides
so find the length and times 3

we need to find the distance betwen the points (-8,-5) and (3,7)

distance between the points (x1,y1) and (x2,y2) is
$D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$
so
distance between (-8,-5) and (3,7) is
$D=\sqrt{(-8-3)^2+(-5-7)^2}$
$D=\sqrt{(-11)^2+(-12)^2}$
$D=\sqrt{121+144}$
$D=\sqrt{265}$

the distance is √265
the perimiter is 3√265 units

determine whether AB and CD are parallel, perpendicular,or neither. A(-1,-4), B(2,11), C(1,1), D(4,10)

sergiy2304 [10]

Step-by-step explanation:

the x distance from A to B is 3 (from -1 to 2), and the y distance is 15 (from -4 to 11).

the x distance from C to D is also 3 (from 1 to 4), but the y distance is 9 (from 1 to 10).

so, the slopes are different

AB : 15/3 = 5

CD : 9/3 = 3

and the lines are therefore not parallel.

perpendicular slopes are simply inverting y and x in the ratio and flip the sign (from - to + and vice versa). but that is not the case here either (just to start - both slopes are positive).

so, the 2 lines are "neither".
