Work out b(4½-3⅔)+1⅔

Zolol [24]

Answer:

2 $\frac{1}{2}$

Step-by-step explanation:

Change the mixed numbers to improper fractions

( $\frac{9}{2}$ - $\frac{11}{3}$ ) + $\frac{5}{3}$ ← the LCM of 2 and 3 is 6

= $\frac{9(3)}{2(3)}$ - $\frac{11(2)}{3(2)}$ + $\frac{5(2)}{3(2)}$

= $\frac{27}{6}$ - $\frac{22}{6}$ + $\frac{10}{6}$

= $\frac{5}{6}$ + $\frac{10}{6}$

= $\frac{15}{6}$

= $\frac{5}{2}$

= 2 $\frac{1}{2}$

Anita plans to give her husband 3 shirts for his birthday. She narrows the search to 3 shirts from a selection of 17 shirts at D

Lunna [17]

Using the combination formula, it is found that she can select the shirts in 775,200 ways.

The order in which the shirt are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.

Combination formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem:

3 shirts from a set of 17.

Then, 3 shirts from a set of 20.

They are independent, hence, to find the total, we multiply both combinations.

$T = C_{17,3} \times C_{20,3} = \frac{17!}{3!14!} \times \frac{20!}{3!17!} = 680 \times 1140 = 775200$

She can select the shirts in 775,200 ways.

Answer:

∠A = ∠D (**but very important Δ ABC has to be congruent to Δ DEF)

Step-by-step explanation:

It will help if you draw the triangles out and label the same sides. Then according to the side-angle-side (SAS) rule, ∠A should be equal to ∠D
