Answer: $6.50
If the number is below 5 (so 1-4) you round down. If its above 5 (5-9), you round up.
E.G. 78.89
Round this to the nearest 10th, you'll get 78.90

Elza [17]

Answer:

Step-by-step explanation:

Fill in the variable value and do the arithmetic.

$\dfrac{2^5}{2^2}=\dfrac{32}{4}=8$

___

Of course, the fraction can be simplified first:

$\dfrac{x^5}{x^2}=x^{5-2}=x^3\\\\2^3=8$

A park ranger hiked 3/4 mi to a lookout, another 5/7 mi to a bird's nest, and finally 5/14 mi to a campsite. How far did the par

dusya [7]

Answer:

2 miles and 88 yards.

Step-by-step explanation:

4 has 2*2 as prime factors

5 is prime

10 has 2 and 5 as prime factors

Thus, the lowest common denominator will be 2*2*5

3/4=15/20

3/5=12/20

7/10=14/20

Now that we have three fractions with the same denominator, we can add the numerators

15+12+14=41

So 41/20ths

That’s 2 and 1/20th

So the final answer is 2 miles and 88 yards! :)

J and M are base angles of isosceles trapezoid JKLM. If mJ = 20x + 9, and mM = 14x + 15, find mK.

Rainbow [258]

20x + 9 = 14x + 15
6x = 6 
x = 1 

 So base angles are 20 + 9 means 29 degrees. To calculate the m of angle k, subtract 29 from 180: 

180 - 29 = 151 degrees.
hope it helps
