I believe the answer is 3. Because if you have a ratio that is 2:1 and Evan has 6 then it would be 6:x and so you just divide two? I hope that is correct! :)
Sqrt 155 = 12.45
so it lies between 12 and 13
Answer:
56 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(a + b)
where h is the perpendicular height and a, b the parallel bases
here h = 4, a = 5 + 9 + 5 = 19 and b = 9, thus
A = × 4 × (19 + 9) = 2 × 28 = 56 cm²
The height of the toy dinosaur will be 32 inches.
<h3>What is scaling?</h3>
In mathematics scaling is defined as the enlarging or contracting of the size of an object by reducing or increasing the units of the measurements of the object.
Given that:-
An adult mamenchisaurus dinosaur was about 24 feet tall. if a toy model of the dinosaur is made to the scale of 1 inch to 9 inches.
The new height of the dinosaur will be calculated as:-
We know that the size of the dinosaur is scaled as 9 inches to 1 inch the actual height of the dinosaur is 24 feet so the scaled height will be:-
Actual height = 24 ft = 24 x 12 = 288 inches
9 inches → 1 inch
288 inches → 288 / 9 = 32 inches.
Therefore the height of the toy dinosaur will be 32 inches.
