Sarah made a scale drawing of a dinosaur she made the height of the dinosaur 2 1/2 inches the actual height of dinosaurs 9 feet

what scale does Sarah use for drawing

Answer:

The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)

Step-by-step explanation:

Here, we want to know the scale used for the drawing of the Dinosaur by sarah.

The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)

Mathematically, we know that 1 foot is 12 inches;

So the actual height of the Dinosaur is 9 * 12 = 108 inches

So practically, what she has done is to represent a height of 108 inches by 2.5 inches

So the scale factor used will be;

108/2.5 = 43.2

The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual

Pls help me on this question :-
Nastasia [14]

Answer:

We conclude that the rule for the table in terms of x and y is:

  • y = 3x+2

Step-by-step explanation:

The table indicates that there is constant change in the x and y values, meaning the table represents the linear function the graph of which would be a straight line.

We know the slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept.

Taking two points

  • (-2, -4)
  • (-1, -1)

Finding the slope between (-2, -4) and (-1, -1)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-2,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-1\right)

m=\frac{-1-\left(-4\right)}{-1-\left(-2\right)}

m=3

We know that the y-intercept can be determined by setting x = 0 and finding the corresponding y-value.

Taking another point (0, 2) from the table.

It means at x = 0, y = 2.

Thus, the y-intercept b = 2

Using the slope-intercept form of the linear line function

y = mx+b

substituting m = 3 and b = 2

y = 3x+2

Therefore, we conclude that the rule for the table in terms of x and y is:

  • y = 3x+2

45 =p x 60 <br> NEED HELP ASAP
Alexus [3.1K]

Answer:

p = 3/4 or 0.75

Step-by-step explanation:

your equation: 60p = 45

divide both sides by 60: p = 45/60

simply the fraction by dividing the numerator and denominator by 15: p = 3/4

your answer: 3/4 or 0.75
