Answer:

$1025

Step-by-step explanation:

31 x 10= 310

14 x 5= 210

4 x 2= 8

62 x 1= 1

and that was the bills, add them together, you get 529.

then multiply the amount of what the change is by the amount of change there is so, 13 x 25= 325 3 x 5= 15 and 93 x 1= 93.

add the change

325+15+93= 433

add the amount of how much each totals were worth:

433+592 = $1025

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. q2+11q

Sedbober [7]

Answer:

$(q+\frac{11}{2})^2-\frac{121}{4}$

Step-by-step explanation:

We have been given an expression $q^2+11q$ . We are asked to complete the square to make a perfect square trinomial. Then, write the result as a binomial squared.

We know that a perfect square trinomial is in form $a^2+2ab+b^2$ .

To convert our given expression into perfect square trinomial, we need to add and subtract $(\frac{b}{2})^2$ from our given expression.

We can see that value of b is 11, so we need to add and subtract $(\frac{11}{2})^2$ to our expression as:

$q^2+11q+(\frac{11}{2})^2-(\frac{11}{2})^2$

Upon comparing our expression with $(a+b)^2=a^2+2ab+b^2$ , we can see that $a=q$ , $2ab=11q$ and $b=\frac{11}{2}$ .

Upon simplifying our expression, we will get:

$(q+\frac{11}{2})^2-\frac{11^2}{2^2}$

$(q+\frac{11}{2})^2-\frac{121}{4}$

Therefore, our perfect square would be $(q+\frac{11}{2})^2-\frac{121}{4}$ .

A math class has 7 girls and 3 boys in the seventh grade and 3 girls and 9 boys in the eighth grade. The teacher randomly select

Bumek [7]

7th grade has 3 boy out of 10 students

probability of picking a boy is 3/10

8th grade has 9 boys out of 12 students are boys

probability of picking a boy is 9/12 reduced to 3/4

3/10 x 3/4 = 9/40 probability of picking 2 boys
