Answer:

110 students walk or bike to school.

Step-by-step explanation:

48% of the 208 students walk, whereas 5% bike.  Combining 48% and 5%, we get 53%.  

53% of the total number, n, comes to 208 students.

This number is 0.53(208 students), or 110 students.

110 students walk or bike to school.

Find the value of the variable.
nalin [4]

Answer:

The variable, y is 11°

Step-by-step explanation:

The given parameters are;

in triangle ΔABC;          {}              in triangle ΔFGH;

Segment \overline {AB} = 14         {}               Segment \overline {FG} = 14

Segment \overline {BC} = 27         {}              Segment \overline {GH} = 19

Segment \overline {AC} = 19         {}               Segment \overline {FH} = 2·y + 5

∡A = 32°                       {}                ∡G = 32°

∡A = ∠BAC which is the angle formed by segments \overline {AB} = 14 and \overline {AC} = 19

Therefore, segment \overline {BC} = 27, is the segment opposite to ∡A = 32°

Similarly, ∡G = ∠FGH which is the angle formed by segments \overline {FG} = 14 and \overline {GH} = 19

Therefore, segment \overline {FH} = 2·y + 5, is the segment opposite to ∡A = 32° and triangle ΔABC ≅ ΔFGH by Side-Angle-Side congruency rule which gives;

\overline {FH} ≅ \overline {BC} by Congruent Parts of Congruent Triangles are Congruent (CPCTC)

∴ \overline {FH} = \overline {BC} = 27° y definition of congruency

\overline {FH} = 2·y + 5 = 27° by transitive property

∴ 2·y + 5 = 27°

2·y = 27° - 5° = 22°

y = 22°/2 = 11°

The variable, y = 11°

An $42 item was marked down by 50%<br><br> what is the new cost of the item?
Nataly_w [17]

Answer:

New Cost of item is \$ 21

Step-by-step explanation:

Given:

Original Cost of item = \$ 42

Item was marked down by 50\%

To Calculate Cost after 50\% marked  down we need to multiply original cost by 50 and then divide by hundred.

Cost after  marked down = \frac{42 \times 50}{100}= \$21

Now New cost of the item is calculated by Subtracting Cost after 50\% marked down by Original Cost of item.

New cost of the item =  \$ 42 - \$ 21 = \$21
