Sanic ran 420 meters in 21 seconds what was his speed?


Yes this is a real question please help

Answers

Answer 1

Answer:

the speed is 20 m/s

Step-by-step explanation:

The computation of the speed is as follows

As we know that

Speed = Distance ÷ time

where,

Distance is 420 meters

And, the time is 21 seconds

So, the speed is

= 420 ÷ 21

= 20 m/s

hence, the speed is 20 m/s

We simply applied the above formula so that the correct value could come

And, the same is to be considered

how do you solve 6x+104=16x+114

Answers

Answer:

x = -1

Step-by-step explanation:

6x + 104 = 16x + 114

First subtract 104 from both sides

Now you have:

6x = 16x + 10

Subtract 16x from both sides

-10x = 10

Divide by -10 on both sides and you get your answer

x = -1

Answer:

x = - 1

Step-by-step explanation:

First you wanna subtract 104 from both sides

6x + 104 - 104 = 16x + 114 - 104

you should get 0 on the left and 10 on the right

next you subtract 16x from both sides  

6x - 16x = 16x - 16x + 10

you should get -10x on the left side and get 0 on your right

next you divide both side by -10

-10x ÷ -10 = 10 ÷ -10

the left should be 0 and the right should be -1

that's how i got the answer and I hope it helped !

Answers

In a true experimental design, the manipulated variable, or grouping variable is  independent variable; based on pre-existing difference.

What is the independent variable?

The independent variable is the variable in an experiment that is manipulated by the researcher. It is assumed that the independent variable has a direct effect on the dependent variable. The dependent variable is the variable whose value is being determined  in the experiment.

For example, you want to carry out an experiment to determine the effect of the hours spent reading for a test on the grade gotten on the grade. In this research, the independent variable is the hours spent reading and the dependent variable is the grade gotten. Different data on the hours studied would be collected.

Sam noticed that some people purchased like items and decided to start offering a bundle. If you buy the following items together, you get 15% off. How much will the bundle cost? $11.00 snorkle $30.00 for goggles $36.00 for flipperd​

Answers

Answer: $65.45

Step-by-step explanation:

Cost of Snorkle = $11.00

Cost of goggles = $30.00

Cost for flippered = $36.00

Total cost = $11.00 + $30.00 + $36.00 = $77.00

Since there's a 15% off, the cost of the bundle will be:

= $77 - (15% × $77)

= $77 - (0.15 × $77)

= $77 - $11.55

= $65.45

Hello!

Find "B" by plugging in the x and y values into the equation given:

-7x + By = 31

-7(-7) + B(2) = 31

49 + 2B = 31

Subtract 49 from both sides:

2B = -18

Divide both sides by 2:

2B / 2 = -18/2

Step-by-step explanation:

1, 2, 3, and 4 and 9, 10, 11, and 12 can be solved using the vertical angle and supplementary angle rules. Vertical angles are always the same and supplementary angles always add up to 180. But to find 5, 6, 7, and 8, you need to find 5 using the rule where all the angles in a triangle add up to 180. Since we know the angles for 9 and 3, we can find the angle 5 and then we can finish finding the rest of the angles.
