Hannah is saving money for a car. She earns $160 each week working part time after school and on the weekends at Papa's Pizza. H

Yuliya22 [10]

From the problem we know that Hanna saves one-half of her paycheck each week, so she saves $( \frac{1}{2})(160)= \frac{160}{2} =80$ . Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is $80+50=130$ .
Since we know that Hanna currently has $1,280 in her saving's account and each week she and her parents deposit $130 to the account, with $n$ representing the number of weeks, we can model the situation as follows:
$f(n)=1280+130n$

Using Euler’s formula, how many edges does a polyhedron with 20 faces and 12 vertices have?

astra-53 [7]

Euler's formula for a polyhedron is given by:

$\begin{gathered} F+V=E+2 \\ \text{where,} \\ F=\text{faces} \\ V=\text{vertices} \\ E=\text{edges} \end{gathered}$

Make E, the subject of the formula:

$\begin{gathered} F+V=E+2 \\ E=F+V-2 \end{gathered}$

Put F = 20, V = 12, to obtain E,

$\begin{gathered} E=20+12-2 \\ E=30 \end{gathered}$

Therefore, there are 30 edges

mr. cuddy draws a triangle with a perimeter of 36cm. Principal Aranda says that the longest side measures 18 cm, How do you know

hichkok12 [17]

Answer:

See the procedure

Step-by-step explanation:

we know that

The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

a,b,c the lengths side of triangle

c is the greater side

The perimeter is equal to

P=a+b+c

P=36 cm

If c=18 cm

then

a+b=18

Applying the Triangle Inequality Theorem

a+b > c

18 > 18 ----> is not true

therefore

Principal Aranda is incorrect

The larger side cannot measure 18 cm

The largest side must be less than 18 cm
