Write 36.14 in expanded form

Answers

The correct answer is:


30 + 6 + 0.1 + 0.04.


Explanation:


We write numbers in expanded form using place value.


3 is in the tens place; this makes its value 30.

6 is in the ones place; this makes its value 6.

1 is in the tenths place; this makes its value 0.1.

4 is in the hundredths place; this makes its value 0.04.


Together we find the sum:

30 + 6 + 0.1 + 0.04.

we can write 36.14 in an expanded form as:
36.14 = (3 x 10) + (6 x 1) + (1/10) + (4/100)
and the expanded form with decimals is:
36.14 = 30+6+0.1+0.04

Find the lateral surface area and the total surface area for the pyramid .

Answers

Answer:

Lateral Surface Area: 56 in²

Total Surface Area: 81 in²

Step-by-step explanation:

To find the lateral surface area, all we need to do is find the surface area for one of the lateral faces and then multiply it by 4.

(1)/(2) *b*h

(1)/(2) *5*5.6=2.5*5.6=14

Now the area of all the lateral faces:

14*4=56

The total surface area is the lateral area plus the base.

56+(5*5)=56+25=81

X is 25% of 104, 7 is 10% of y, and n is 80% of y. y is what percent of (n+y−x)(n+y−x)

Answers

The correct answer is 100000/7 %

How to solve the problem?

The given percentage of xis 25% of 104

x =(25)/(100)*104

x = 26

7= 10% of y

7=10/100*y

Therefore , y = 70

Now, (n+y-x)(n+y-x) = % of y

(56+70-26)(56+70-26)= 100*100

= 10000 = % of y

let % be m %

10000= m / 100*y

10000= m/100*70

m = 100000/7%

There are 3 local maxima and minima. These are the points that are the highest and lowest points respectively within a given region of the graph. In other words, they are the hill and valley points. In general, a shorthand way of saying "maxima and minima" is to simply say "extrema"

There are 2 inflection points. This is because there is a concave up region followed by a concave down region, then after that is a concave up region. Each change from concave down to up, or vice versa, introduces an inflection point in between.

There are 4 branches to this curve, so the degree is most likely 4. Even degree functions have both endpoints aimed in the same direction.
