How do I solve 4/9+9/2 and write my answer as a mixed number?

jenyasd209 [6]

9 has factors of 3*3.

2 is prime, so no factors.

from those two denominators, we can get the LCD of hmmm simply their product, namely 18.

$\bf \cfrac{4}{9}+\cfrac{9}{2}\implies \stackrel{\textit{using the LCD of 18}}{\cfrac{(2)4+(9)9}{18}}\implies \cfrac{8+81}{18}\implies \cfrac{89}{18}\implies 4\frac{17}{18}$

now, recall that, to get the mixed fraction, we divide 89 ÷ 18, the quotient goes up front, the "4", and the remainder is the one atop, the "17".

On a coordinate grid, point R is at (−6, 2) and point S is at (8, 2). The distance (in units) between points R and S is ______.

Talja [164]

You can use the distance formula:
d=sqroot(x2-x1)squared + (y2-y1)squared.
Plug in values: d=sqroot(8-(-6))squared + (2-2)squared
Simplify: d=sqroot(196)+0
Simplify:d=sqroot(196
Square Root: d=14 units

Ok I need help ASAP pls like right now points are going giving and mark brainless pls help I need answers for 1,2,3

Schach [20]

Answer:

1. 30 student

2. 120 student's didn't vote

3. 7 quarters

Step-by-step explanation:

1. first, see how many games can be played:

45÷3 = 15

then, multiply the number of games by two because 2 students can play per game

15 • 2 = 30

2. first, figure out what percent of students did not vote:

100 - 60 = 40%

then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:

300 • .40 = 120 student's didn't vote

3. first, find how much 9 dimes is:

1 dime = $0.10

9 dimes = 9 • $0.10 = $0.90

then, find how much money kerry had:

$2.65 - $0.90 = $1.75

finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:

1 quarter = $0.25

$1.75 ÷ $0.25 = 7 quarters

Find the distance between the points (6,5√5) and (4,3√2).<br> 2, 2√2, 2√3

FromTheMoon [43]

Answer:

D= $\sqrt{(147-30\sqrt{10}}$

Step-by-step explanation:

Here we are required to find the distance between two coordinates. We will use the distance formula to find the distance

The distance formula is given as

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Here we are given two coordinates as

$(6,5\sqrt{5} ) , (4,3\sqrt{2} )$

Substituting these values in the Distance formula given above we get

$D=\sqrt{(6-4)^2+(5\sqrt{5} -3\sqrt{2}) ^2}$

$D=\sqrt{(2)^2+(5\sqrt{5})^2+(3\sqrt{2})^2-2*5\sqrt{5}*3\sqrt{2}}\\$

$D=\sqrt{4+125+18-2*15\sqrt{10}}\\D=\sqrt{147-30\sqrt{10}}\\$

Hence this is our answer
