Answer:

x=4.8

Step-by-step explanation:

5x:9 = 8:3

It can also be written as

5x/9 = 8/3

Cross multiply

5x*3 = 8*9

15x = 72

Divide both sides by 15

15x/15 = 72/15

x =4.8

A graph titled Cost of a Lunch in a School's Cafeteria has Days since school started on the x-axis and cost of lunch (dollars) o
denpristay [2]

The true statement about the graph's slope is (c) Its slope is zero.

<h3>How to determine the true statement?</h3>

From the question, we have:

A horizontal line is at y = 2.5.

The horizontal line implies that the cost of lunch do not change

Horizontal lines have a slope of 0

Hence, the true statement about the graph's slope is (c) Its slope is zero.

Jason is traveling by car from his home to his office. He has gone 3.5 miles so far. From this point on, he can cover 100 miles
Elden [556K]
First the equation needs to be set to "y" to find the total amount of miles traveled:
y=
Then you know he has already gone 3.5, this is a constant and can be added to the graph immediately
y=3.5
Then you know every two hours he can cover 100 miles, which means 50 miles per hour or 50 per x, so add 50x to 3.5 to show that he will go 3.5 miles plus 50 miles for every hour he is traveling.
y=3.5+50x

The side of a square is 2.5 cm. Find its perimeter and area.​
Neko [114]

Answer:

Perimeter = 10 cm

Area = 6.25 cm²

Step-by-step explanation:

\bf \: Given :

\sf \: Side  \:  of \:  the \:  square = 2.5 \: cm

\bf \: To \:  find:

\rightarrow \sf \: Perimeter

\sf\rightarrow Area

\bf \: Solution :

\rm \: First \:  w e \:  need \:  to \:  find  \: out  \: the  \: perimeter \:  o f \:  it.

So to find the Perimeter of the square, we'll use this formula :

\boxed{  \sf\longrightarrow \: Perimeter = 4 \times side}

\bf \: Step  \: 1 : \rm \:  Put \:  the  \: value  \: of   \: side \:  of \:  the  \: square :

\sf\longrightarrow \: Perimeter = (4 \times 2.5)cm

\bf \: Step\;2 : \rm Multiply :

\sf\longrightarrow \: Perimeter  = 10 \: cm

Hence, the perimeter would be 10 cm .

\rule{225pt}{2pt}

\sf \: Now,\; let's\; find  \: the  \: Area .

We know that the formula of Area to find the square is,

\boxed{ \sf \longrightarrow \: Area = (side) {}^{2} }

Note : The answer would always be in cm².

\bf Step\;  1  :\rm Put\;  the\; value \; of\;  side \; of \; the\; square :

\sf\longrightarrow{Area} = (2.5) {}^{2}  \: cm {}^{2}

\sf\longrightarrow{Area} = (2.5 × 2.5 ) \: cm {}^{2}

\bf \: Step\;2 : \rm Multiply :

\longrightarrow\sf \: Area = 6.25 \: cm {}^{2}

Hence, the area of the square would be 6.25 cm².

<em>We are done !</em>

\rule{225pt}{2pt}

I hope this helps!

Let me know if you have any questions.
