Answer:

A corda deve ter um comprimento mínimo de 80 cm.

The string should have a minimum length of 80 cm.

Step-by-step explanation:

Espera-se que a corda seja colada em todo o contorno da moldura quadrada.

Isso significa que a cadeia precisa cobrir pelo menos todo o perímetro da moldura quadrada pelo menos uma vez.

Perímetro de um quadrado = 4L

L = comprimento lateral do quadrado.

O comprimento lateral da moldura quadrada = 20 cm

Comprimento mínimo da corda necessária = Perímetro da moldura quadrada = 4 × 20 = 80 cm.

Espero que isto ajude!!!!

English Translation

Sofia is going to glue a piece of string to the outline of a square frame 20 cm from the side. How long should this string be?

Solution

The string is expected to be glued all around the outlne of square frame.

This means the string needs to at least cover the whole perimeter of the square frame a minimum of one time.

Perimeter of a square = 4L

L = side length of the square.

The side length of the square frame = 20 cm

Minimum length of the string required = Perimeter of the square frame = 4 × 20 = 80 cm.

Hope this Helps!!!!

What equation is represented by the equation on the graph ?
solmaris [256]

Answer: The correct option is D.

Explanation:

From the graph we noticed that the x intercept of the line is (2,0) and the y-intercept is (0,2).

If the line passing through two points then the equation of line is,

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Since the ien passing through (2,0) and (0,2).

y-0=\frac{2-0}{0-2}(x-2)

y=-1(x-2)

y=-x+2

This equation is represented by option D, therefore the option D is correct.

Over [174]

Answer:

\large \boxed{\$9.00}

Step-by-step explanation:

Let p = the original price of the ticket

\begin{array}{rcl}\text{ Price before discount - discount} & = & \text{sale price}\\p - 0.15p & = & 7.65\\0.85p & = & 7.65\\p & = & \dfrac{7.65 }{0.85}\\\\& = & \mathbf{9.00}\\\end{array}\\\text{The original price of the ticket was $\large \boxed{\mathbf{\$9.00}}$}

Check:

\begin{array}{rcl}9.00 - 0.15(9.00) & = & 7.65\\9.00 - 1.35 & = & 7.65\\7.65 & = & 7.65\\\end{array}

OK.

Gavin went on 25 runs last month that totaled 103 miles. Each run was a distance of either 3 miles or 5 miles. Which system of
Aleksandr [31]

Answer:

3x+5y=105

x+y=25

Step-by-step explanation:

x is the number of 3 mile runs so the total distance travelled is 3x miles.  y is the number of 5 mile runs so the total distance travelled is 5y miles.  Together Gavin travelled 103 miles so 3x+5y=105.  

The number of 3 mile and 5 mile runs he did in total were 25 so x+y=25.  

So the answer is:

3x+5y=105

x+y=25

Done.
