Answer:
36 red blocks.
Step-by-step explanation:
3/4 (.75)*48 = 36
Answer:
Step-by-step explanation:
Put everything on the same side of the equals sign and set it equal to zero so you can factor it.

. In order to factor that you have no choice really but to put it into the quadratic formula. When you do that you find that your zeros are x = 9.623475383 and -.623475383
$1.87
60 cents in pennies = $.60
Each quarter is $.25, each dime is $.10, and each nickel is $.05.
1.87=q*.25+d*.10+n*.05+.60
Sec(x/2) = 1/cos(x/2)
sec(x/2)=cos(x/2) ----> cos^2(x/2)=1 ---> cos(x/2) = -1 and cos(x/2) = 1
Cos(x/2)=1 --- > x/2 = 0, only. x = 0;
cos(x/2)=-1 ----> x/2 = pi -> x = 2pi. But the statement says [0,2pi), so 2pi can not be chosen.
Only x = 0.
In fact, your equation is equivalent to sec(x)=cos(x), for x in [ 0, pi), so yes, only x = 0 .
