I am looking to decrease my bill by 25%. Can you look at my current plan and tell me what I can remove to achieve this reduction
Gennadij [26K]

Answer: $35

Step-by-step explanation:

From the question, we are informed that the current bill of the person is $140.00 per month and that the person wants to decrease the bill by 25%.

To know the amount that the person needs to deduct, we have to calculate 25% of $140.00. This will be:

= 25% of $140

= 25/100 × $140

= 1/4 × $140

= 0.25 × $140

= $35

The person will need to remove $35. The person will now pay ($140 - $35) = $105 monthly.

What 1 thruogh 100 added up them divided
Marina CMI [18]
We can use the sum of an aritmetic sequence
the sum from n=1 to n=r when the first term is a1 and the nth term is an is
S=\frac{n(a_1+a_n)}{2}
first term is 1
last term is 100
there are 100 terms so n=100

so the sum is S=\frac{100(1+100)}{2}
S=(50)(101)
S=5050
now you want us to divide by 10
5050/10=505


fun fact, gauss (famous math guy) did this when he was younger, legend has it that he was assigned this as an in class assigment to kill time but gauss found a neat pattern, he noticed that adding the end terms wer giving the same sum, example, 100+1=101, 2+99=101, etc, so he just needed to find al the pairs and add them all up




answer is 505
the result is 505

Find the area. The figure is not drawn to scale.
VMariaS [17]

The figure on the top left is a triangle with base 11 and height 8, for an area of

A_1=\dfrac{11\cdot 8}{2}=44

Immediately below, we have a rectangle with dimensions 11 and 9, for an area of

A_2=11\cdot 9=99

Moving to the right, we have a parallelogram with base 9 and heght 11, which again has height

A_3=11\cdot 9=99

Finally, the rightmost figure is a triangle with base 8 and height 9, for a total of

A_4=\dfrac{8\cdot 9}{4}=36

Sum these areas and you'll get the total area

What is the easiest way to re learn ratios
enot [183]

Answer:

Step-by-step explanation:

Ratios are no different from fractions. They are "comparisons" of 2 or more things. Instead of fraction bars, they use colons to separate 2 different things.

For example:

\frac{1}{2}=1:2

Now, let's do an example problem.

Ex: find the ratio of 5 cats to every dog.

We are comparing 5 cats to every 1 dog, so the ratio is:

5:1

Don't make thing more complicated to yourself, and don't overthink it. They are exactly like fractions. So treat them as such!
