Step-by-step explanation:
An integer is a positive or negative whole number. Because -199.46 is a decimal, it is not an integer.
Answer:
Step-by-step explanation:
Since, the given question is incomplete but to solve these kind of questions,
Use the formula of the scale factor,
Scale factor = ![\frac{\text{Length of one dimension of the dilated image}}{\text{Length of one dimension of the preimage}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BLength%20of%20one%20dimension%20of%20the%20dilated%20image%7D%7D%7B%5Ctext%7BLength%20of%20one%20dimension%20of%20the%20preimage%7D%7D)
From the question ΔE'F'G' is the image formed by the dilation of preimage ΔEFG.
Therefore, ![\frac{2}{3}=\frac{F'G'}{FG}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7BF%27G%27%7D%7BFG%7D)
FG = ![\frac{3}{2}(F'G')](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%28F%27G%27%29)
By substituting any value of F'G' given in the question we can evaluate the measure of side FG.
Answer:
circumference of the circle=2πr
![2 \times 3.142 \times 0.9 \\5.6556cm](https://tex.z-dn.net/?f=2%20%5Ctimes%203.142%20%5Ctimes%200.9%20%5C%5C5.6556cm%20)
5.7 cm
Answer:
Step-by-step explanation:
5 1/2 ÷ 2 1/2
= 11/2 ÷ 5/2
= 11/2 × 2/5
= 11/5
= 2 1/5
