Answer: x = 1
Step-by-step explanation:
we have
x tetras
3 goldfish
5 platies.
the total number of fishh in the bowl is x + 3 + 5
The probability of removing a gold fish is equal to the number of gold fish divided by the total number of fish, this is:
p = 3/(x + 3 + 5) = 1/3
3 = (1/3)(x + 3 + 5) = x/3 + 1 + 5/3
9 = x + 3 + 5
x = 9 - 8 = 1
then wemust have that x = 1
because 1 + 3 + 5 = 9
and 3/9 = 1/3
Answer:
2(3x)+2(2x+22)+x+41=360°
Step-by-step explanation:
Sum of exterior angles of any polygon is 360°.
So if we add up all five exterior angles of the pentagon, we have
The temperature fell by 24 degrees in 6 hours. We need to find out how many degrees did the temperature fall every hour.
You can <u>divide</u> 24 with 6.
24 ÷ 6 = 4
Your answer is 4
hope this helps!
Answer: Dilation and stretch
Step-by-step explanation:
- Rigid transformations that are also called as isometry are the transformations which preserves the side lengths and the angle measures of a polygon. It does not affect the size of the shape. The shape doesn't shrink or get enlarger.
There are four rigid transformations: <em>reflections, rotations, translations and glide reflection.</em>
- Dilation and stretch are non rigid transformation because they change the size of the figure. They produces similar figures.
