The speed of a bus from University A to University B was decreased by 20% to 48 miles per hour. What was the speed of the bus be
Lunna [17]

Answer:

initial speed: 240 m/h

Step-by-step explanation:

48 m/h is the current speed which is the 20% of X

x (20 / 100) = 48

20x = 4800

x = 4800/20

x = 240 m/h

Find the value of sin D rounded to the nearest hundredth, if necessary.
Lynna [10]

Answer:

0.22

Step-by-step explanation:

So in this problem, we have to find the hypotenuse first, since sine is opposite over hypotenuse.

We can do this using the pythagorean theorem (you can search it if you don't know). Or, we can just remember this as one of our pythagorean triplets (9,40,41). The last side will be 41.

We have to find the value of sin(D)

opposite/hypotenuse = 9/41 = 0.2195 which is about 0.22

Solve the following system of equations using substitution.
ollegr [7]

To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.

5x - 4y = -3

5x - 4(3x-5) = -3

5x -12x+20=-3

               -20     -20  

_______________

5x-12x=-23

-7x=-23

___    ____

 -7       -7

x=3.29 (rounded)

Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.

y = 3x-5

y = 3(3.29)-5

y = 9.87-5

y = 4.87

So, your final answer would be (3.29, 4.87).

» Which pair of numbers has an LCM of 60?<br> 2 and 12<br> 5 and 12<br> 6 and 12<br> 3 and 12
Mariana [72]

Answer: 5 and 12

Step-by-step explanation:

2 and 12 is not it   because 12 can be divided by 2 meaning that the LCM of those two numbers will be 12.

6 and 12 is not it because  12 can also be divided  by 6 meaning that the LCM of 6 and 12 is also 12.

3 and 12 is also the same,  12  can be divided by 3 so their LCM will be 12.

With 5 and 12, 12 is not divisible by 5 so  you will have to find the multiples of 5 and 12 and it will eventually be 60.

Multiples of 5:  5, 10,15,20,25,30,35,40,45,50,55,60,65

Multiples of 12:  12, 24, 36, 48, 60, 72  

As it appears in both multiples, 60 is the least number that appears in both multiples so the LCM of 5 and 12 is 60.
