javier rounded to the nearest half to estimate the product of 3 2/5 and -3 7/8. how to the estimate and the actual product compare

Answer:

Step-by-step explanation:

x       - a certain number

6x  -  - six times the number

6x-31    - six times the number less 31

3x        - three times the number

3x-10    -  10 subtracted from  three times the number

so the equation:

6x - 31 = 3x - 10

    +31       +31

 6x  =  3x + 21

 -3x     - 3x

3x  = 21  

 ÷3     ÷3

 x = 7

Check:  6•7-31=42-31=11;   3•7-10=21-10=11

Solution :-

As per provided information in the given question, we have been given that the Radius of a cylinder is 5 meters. The height of a cylinder is 8 meters. We have been asked to find the volume of a cylinder.

To calculate the volume of a cylinder, we will apply the formula below :-

[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: Volume_{(Cylinder)} = \pi r^2 h \: \: }}[/tex]

Substitute the given values into the above formula and solve for Volume :-

[tex]\sf:\implies Volume_{(Cylinder)} = \pi r^2 h[/tex]

[tex]\sf:\implies Volume_{(Cylinder)} = (3.14)(5 \: m)^2(8 \: m)[/tex]

[tex]\sf:\implies Volume_{(Cylinder)} = (3.14)(25 \:m^2)(8 \: m)[/tex]

[tex]\sf:\implies Volume_{(Cylinder)} = (78.5 \:m^2)(8 \:m)[/tex]

[tex]\sf:\implies\bold{Volume_{(Cylinder)} = 628 \: m^3}[/tex]

Therefore :-

Answer:

The difference in cost per mile is $0.94.

Step-by-step explanation:

Uber

7x = 20.37

x = $2.91 per mile

Lyft

4y = 15.4

y = $3.85 per mile

3.85 - 2.91 = 0.94

Hello.

To find the difference in cost per mile, divide the cost by the amount of miles, then subtract the two answers.

20.37 / 7 = 2.91 (cost per mile {cpm} for Uber)

15.40 / 4 = 3.85 (cost per mile {cpm} for Lyft)

3.85 - 2.91 = 0.94

The difference in cost per mile is $0.94

Answer:

3/2

Step-by-step explanation:

Answer:

To find : If 21m, 28m and 49m form a right angle or not.

Logic : To find if this triangle is a right angle, we can use the Pythagoras Theorem, which states that the square if the longest side should be equal to the square of the sum of the other two sides.

The name of the longest side is called the hypotenuse, while the others are called legs or one is the perpendicular and the other the base.

Proof : [tex]h^{2} = p^{2} + b^{2}[/tex]

=> [tex]49^{2} = 28^{2} + 21^{2}[/tex]

=> 2401 = 784 + 441

=> 2401 ≠ 1225

Therefore these side lengths cannot be the lengths of a right angled triangle.
