a car drives 10 1/2 miles in 1/6 hour. what is its speed in miles per hour

Answers

(Credit to guy/girl above) 63 miles 10 1/2 x 6 is 63.

The speed for the given distance and time is 12.6 miles per hour.

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, a car drives [tex]10\frac{1}{2}[/tex] miles in 1/6 hour.

We know that, the formula to find the speed is Speed=Distance/Time

Speed = [tex]10\frac{1}{2}[/tex] ÷ 1/6

= 21/10 ×6/1

= 63/5

= 12.6 miles per hour

Therefore, the speed for the given distance and time is 12.6 miles per hour.

If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?

Answers

120% of a
80% of b

120% = 120/100 =1.2
80%= 80/100 = 0.8

1.2a=0.8b | ÷1.2
1a = 2/3 b

1.2a=0.8b | ÷0.8
1b=1.5a


(a+b) = ((2/3b)+ (1.5a)) =2/3b + 1.5a
*not 100% sure

Answer:

120/100 a = 80/100 b

12/10 a = 8/10 b

10 (12/10) a = 10 (8/10) b

12a= 8b

3a= 2b

a+b in terms of a

b = 3/2×a

a+ 3/2×a = 5/2×a

a+b in terms of b

a = 2/3×b

b + 2/3.b = 5/3×b

5z + 2 = 3z - 10

Show your work and I will give you brainlist ​

Answers

Answer:

z = -6

Step-by-step explanation:

5z + 2 = 3z - 10

Subtract 3z from both sides

2z + 2 = -10

Subtract 2 from both sides

2z = -12

Divide each side by 2

z = -6

So, the answer is z = -6

Here's a riddle
A horse travels a certain distance each day. Strangely enough, two of its legs travel 30 miles each day and the other two legs travel nearly 31 miles. It would seem that two of the horse's legs must be one mile ahead of the other two legs, but of course, this can't be true, since the horse is normal. How is this possible?
You can search the answer

Answers

Answer: the horse does more work on one of the pairs so they went a different distance.

Answer:

The horse operates a mill and travels in a circular clockwise direction. The two outside legs will travel a greater distance than the two inside legs.

Mai started a new exercise program. On the second day, she walked 5 minutes more than on the first day. On the third day, she increased her walking time from day 2 by 20% and walked for 42 minutes. Mai drew a diagram to show her progress.

Answers

Answer:

d = 30 minutes.

day one is equal to 30 minutes

day two is equal to 35 minutes

day three is equal to 42 minutes

Explanation:

The first step is to figure out how much day 2 was worth in total.

Using the model, we can see that 5 of the boxes from day three is equal to day 2.

42/6=7.

One of the boxes equals 7 minutes.

Next we find what all 5 of them equal.

7*5=35.

Day two was worth 35 minutes in total.

The next step is to figure out what d equals. In order to do that, we need to solve the equation:

d + 5 = 35.

subtract 5 from both sides.

d = 30.

Now we know that day one/D is equal to 30 minutes.

Day one: 30 minutes

Day two: 35 minutes

Day three: 42 minutes.

Hope that this is what your looking for. Have a good day and good luck!

In this case the number of ways would be the number of events, in this case the events would be the total number of marbles since any of them can come out. so:

4 + 3 + 3 + 2 = 12

Therefore, the number of ways the event can occur is 12 ways.

Now, in the favorable outcomes of the event, it would come depending on what color the marble would be, whether it be red, blue, yellow or green.

In each color, the number of the favorable outcomes of the event would be the quantity of each marble, that is, 4 for red, 3 for blue, 3 for yellow and 2 for green.
