yanalaym [24]

Answer:

6\frac{3}{8} feet tall.

Step-by-step explanation:

Jebb's Height Calculation:

The heights are given in <em>Mixed Fraction</em>. A mixed fraction is comprised of a whole number and a proper fraction, where as <em>proper fraction </em>is the one whose numerator is less than its denominator and <em>improper fraction </em>is the one whose numerator is greater than its denominator:

Shortest girl in the Sixth Grade = 4\frac{1}{4} feet

<em>Converting the height in improper fraction</em>:

\frac{17}{4} feet

Jebb's Height = 1\frac{1}{2} feet  x The shortest girl height

<em>Converting the height of Jebb in Improper Fraction</em>:

\frac{3}{2} feet x \frac{17}{4} feet

<em>To find the Jebb's height we multiply 3 by 17 and 2 by 4 to get a improper fraction of</em>;

Jebb's Height =  \frac{51}{8} feet

We can convert the above in mixed fraction as follows:

6\frac{3}{8} feet tall.

Harry went to the bakery with $50 to buy cupcakes and fruit tarts. One cupcake costs $3.50 and one fruit tart costs $3. Harry bo
mote1985 [20]

Answer:

28+3x\leq 50

Step-by-step explanation:

We are given the following in the question:

Cost of one cupcake = $3.50

Cost of one fruit tart = $3

Total money Harry have = $50

Harry bought 8 cupcakes and x fruit tarts.

We have to write the inequality giving relation between the total number of cupcakes and fruit tarts Harry can buy the amount of money he has.

Total cost of purchase =

= Total cost of cupcakes + Total cost of fruit tarts

=(8\times 3.50) + (x \times 3)\\=28 + 3x

Now, this total cost of Harry's purchase should be less than than equal to $50.

28+3x\leq 50

is the required linear inequality.
