Answer:
y = 13
z = 11
Step-by-step explanation:
14. We know that if the two triangles are congruent, then the hypotenuses will be the same. So we can say that
6y = 5y + 13
We can solve for y by subtracting 5 y from both sides and find out that y = 13.
15. Again, we know if the triangles are congruent then the two shorter legs will be the same, so we can say that:
3z = z + 22
2z = 22
z = 11
Answer:
11/23 or 0.478
Step-by-step explanation:
1. Find the probability of selecting 2 red chips:
11/23 * 10/22 = 5/23
2. Find the probability of selecting 2 blue chips:
12/23 * 11/22 = 6/23
3. Add the two probabilities:
5/23 + 6/23 = 11/23 = 0.478 (rounded to 3 decimal places)

Answer:
I think it is -5+root-7/2 & -5-root-7/2
Step-by-step explanation:
X would be 60, I don’t know an equation, but you can divide both sides by 4 and get 20% of c is 12, and then you can multiply both sides by 5 to get that 100% of x is 60, hope this helps!
Answer:
Baxter drives at 57 kilometers per hour.
Step-by-step explanation:
In order to find the answer, you have to use the following formula to calculate the speed:
speed=distance/time
distance=399 km
time=7 hours
Now, you have to replace the values in the formula:
speed=399 km/7 hours
speed=57 km/hour
According to this, the answer is that Baxter drives at 57 kilometers per hour.
