Answer: 6 students

What we know:

Students: 24

Students who play checkers: $\frac{2}{3}$

Students who also play sudoku: $\frac{3}{8}$ of the $\frac{2}{3}$

24 ÷ 3 = 8, so 8 × 2 = 16 (students who play checkers)

$\frac{3}{8}$ × 2 = $\frac{6}{16}$

So the answer is,

The scale on a map shows that 1 inch = 30 miles. If there are 4.5 inches between your present location and the place you want to

anastassius [24]

Scale : 1 inch = 30 miles

So, the ratio between the distance on the map and the real distance is 1:30

When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.

Call the miles we have to go : x

1:30 = 4.5:x

(1x4.5):(30x4.5) = 4.5 : x

4.5 : 135 = 4.5 : x

So, x = 135 => We have to go 135 miles to get to the place we want to go.

Find the sum of all coefficients in the following binomial expansion.

natima [27]

Answer:

We can find the sum of all the coefficients by substituting all the variables in the expansion with one.

a. u=1,v=1

sum= $(2*1+1)^{10}$ = $3^{10}$

b.u=1,v=1

sum= $(2*1-1)^{10}$ =1

c.u=1,v=1

sum= $(2*1-3*1)^{11$ =-1

d.u=1,v=1

sum= $(1-3*1)^{11}$ =- $2^{11$

e.i=1

sum= $(1+1)^{10$ = $2^{10$

f.i=1

sum= $(1-1)^{10$ =0

g.i=1

sum= $(1+1)^{200$ = $2^{200$

h.i=1

sum= $(1+1)^{201}$ = $2^{201$
