When adding decimals always line them up 
for example:    5.23
                      +6.35
                       --------
                      11.58

Answer:

Ignore the decimal until its needed

Step-by-step explanation:

Adding decimals is easy. All you need to do is remove the decimals from your simple addition equation, and solve. Then, you need to add the decimal in the depending on the number 2nd place for example

12.00 + 13.00

remove the decimal

1200 + 1300 = 2500

add the decimal

12.00 + 13.00 = 25.00

This is also helpful with decimals that don't have any zeros for example:

12.32 + 45.62

remove the decimal

1232 + 4562 = 5794

add the decimal

12.32 + 45.62 = 57.94

Their are better and more efficient ways to add decimals but if you think on a lower level than others or like to think in a less complex way to help math work be less confusing, then, I would consider this way of adding decimals,

(Thanks)

(Hope this was helpful)

At 2:00 PM a car's speedometer reads 30 mi/h. At 2:10 PM it reads 50 mi/h. Show that at some time between 2:00 and 2:10 the acce
Daniel [21]

Answer: If we define 2:00pm as our 0 in time; then:

at t= 0. the velocity is 30 mi/h.

then at t = 10m (or 1/6 hours) the velocity is 50mi/h

Then, if we think in the "mean acceleration" as the slope between the two velocities, we can find the slope as:

a= (y2 - y1)/(x2 - x1) = (50 mi/h - 30 mi/h)/(1/6h - 0h) = 20*6mi/(h*h) = 120mi/h^{2}

Now, this is the slope of the mean acceleration between t= 0h and t = 1/6h, then we can use the mean value theorem; who says that if F is a differentiable function on the interval (a,b), then exist at least one point c between a and b where F'(c) = (F(b) - F(a))/(b - a)

So if v is differentiable, then there is a time T between 0h and 1/6h where v(T) = 120mi/h^{2}

Dwayne buys ingredients to make a cake. He buys 1 1/2 pounds of flour, 12 ounces of coconut, and 1 1/4 pounds of sugar. What is
AVprozaik [17]

Answer:

3.05 or 31/2 pounds

56 ounces

Step-by-step explanation:

To find the total weight all the weights have to have the same units of measurements

It is either pounds is converted to ounces or ounces is converted to pounds

1. convert ounces to pound

1 ounce = 0.0625

12 ounces = 0.0625 x 12 = 0.75 pounds or 3/4

add together = 1 1/2 + 3/4 + 1 1/4 = 1\frac{1}{2} + \frac{3}{4}  + 1\frac{1}{4}

2\frac{2 +3 + 1}{4} = 2\frac{6}{4} = 3 1/2

2. 16 ounces = 1 pound

flour = 16 x 1 1/2 = 24

sugar = 16 x 1 1/4 = 20

total = 24 + 20 + 12 = 56 ounces

What is the gradient?
notsponge [240]

Answer:

Gradient = 2

Step-by-step explanation:

Gradient of a line = Slope of the line

Since, slope of a line passing through two points (x_1, y_1) and (x_2,y_2) is given by,

Slope = \frac{y_2-y_1}{x_2-x_1}

Given line in the graph passes through two points (1, 0) and (2, 2)

Therefore, slope or gradient of the line = \frac{2-0}{2-1}

                                                                  = 2

Gradient = 2 will be the answer.
