Find the distance between points (5,1) and (3,4) to the nearest tenth

Mathematics
1 answer:
Charra [1.4K]3 years ago
5 0

Answer:

3.6 units (nearest tenth)

Step-by-step explanation:

distance formula

= \sqrt{(x1 - x2)^{2}  + (y1 - y2)^{2} }

Thus, distance between the 2 points

= √[(5 - 3)² + (1 - 4)²]

= √[ 2²+ ( - 3)²]

= √13

= 3.6 units (nearest tenth)

the temperature at noon was -27 degrees . the temperature increased by 13 degrees by 2pm . what was the temperature at 2pm
Aleks [24]
First, you would create an equation for this problem. 
-27 + 13

Now, all you would have to do is solve it. 
-27 + 13 = -14

By 2 pm the temperature was -14 degrees. 

I hope this helps!

A new soup recipe contains 3 3 % 33% less sodium per serving than the old soup recipe. The old soup recipe contained x x milligr
Sergio039 [100]

Answer:

(1-33/100)x and 0.67x

Step-by-step explanation:

33% is 33 out of 100, or 33/100.  Since the new recipe has 33%, or 33/100, less sodium, this means we take x, the amount in the old soup, and subtract 33/100 from it:

1 - 33/100 would represent the percent of sodium remaining, and x is the original amount, giving us (1-33/100)x.

If we write this percent as a decimal, we get 0.33.  Taking this away from 100%, which is written in decimal form as 1, we get

1 - 0.33 = 0.67

Now we multiply this by the original amount of sodium, x:

0.67x

hjlf

Answer:

P odd number, then 20) = 1 /14

Step-by-step explanation:

P( odd number) =  number of odd numbers/ total

number of odd numbers = 3

total = 7

P( odd number)   = 3/7

We keep the tile so that there are only 6 tiles left

P (20) = number of 20/ total

          = 1/6

We multiply the probabilities together

P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14

Can someone explain how to solve this?
svetoff [14.1K]

Answer:

21.5

Step-by-step explanation:

x is the radius of the circle.

If we draw a line from the circle's center to either end of the horizontal line, that line will also be a radius, so it will have length x.  This forms a right triangle with side lengths 10 and 19 and hypotenuse x.

Using Pythagorean Theorem:

c² = a² + b²

x² = 10² + 19²

x² = 461

x ≈ 21.5
