Answer:
all positive inegers
Step-by-step explanation:
well, what is 9,744/2,280? take that and move the decimal point two places to the right to find the answer.
Answer:
see explanation
Step-by-step explanation:
Given
V = πr²h ( isolate r² by dividing both sides by πh )
= r² ( take the square root of both sides )
= r
Answer:
L' = 26cm
W' = 39cm
Step-by-step explanation:
a) Given the dimension of the shape;
length L = 10cm
Width W = 15cm
After dilating by a scale factor os 2.6
New length L' = 2.6(10) = 26cm
New width = W' = 2.6(15) = 39cm
Hence the length of each sides of the dilated image are 26cm and 39cm
b) The new image will be similar to the given image but of with the resulting length gotten in (a).

Answer:
I, III
Step-by-step explanation:
You know from your study of the Pythagorean theorem that a triangle with sides 3, 4, and 5 will be a right triangle. Any scaled version of this triangle will also be a right triangle, so it is helpful to learn to recognize when scaled values of these numbers are used.
I -- the scale factor for a 3-4-5 right triangle is 2/10
II -- no isosceles right triangle has integer side lengths. (not a right triangle)
III -- the scale factor for a 3-4-5 right triangle is 1/13
IV -- the lengths do not form a triangle
Triangles I and III are right triangles.
_____
<em>Additional comment</em>
The sides of an isosceles right triangle have the ratios 1 : 1 : √2. The square root of 2 is irrational. No scaled version of this triangle can have rational side lengths.
