Answer:
40 minutes
Step-by-step explanation:
The least common multiple of 8 minutes and 10 minutes is ...
LCM(8, 10) = 8·10/GCD(8, 10) = 80/2 = 40
The red and blue trains will arrive together again in 40 minutes
Why 69 though????????????????????????
Answer:
8.717 both the sides
Step-by-step explanation:
Given:
Let ABC be the given triangle with
angle A= 55
angle B=55
angle C= 70
side across angle C, c= 10 inches
side across angle B, b =?
aide across angle A,a=?
Now using the law of sin to find a and b:
a/sinA=c/sinC
a= (c/sinC)(sinA)
Putting the values:
a= (10/sin70)(sin55)
a= 8.717
As the given triangle is isosceles so side a=b
hence a=b= 8.717 inches !
Answer: x=6 y=3 z=2
Step-by-step explanation: The question is very vast so im guessing that its just finding 3 whole numbers that can equal the same ammount being multipied by 2 and 3. I chose 6. But theres many others. The answer should be correct because if we replace the letters with the numbers i put in the answer it should look like this: 6=2•3=3•2
When we do simplify this we should get 6=6=6 which is true.
Again you can use different numbers for example 12 as X. Then you need to divide 12 by whats behind the Y. So 12÷2 is 6. So Y is equal to 6. To find Z all you need to do is follow the same steps as Y. Find the number behind Z (3) and divide that into 12. So it would be 12÷3. And if you do the math right it should look like this: X=12, Y=6, Z= 4. And when you imput the numbers to thier corresponding letter it should look like this 12=2(6)=3(4) which simplified looks like 12=12=12 which is true.
