mark invested a certain amount at 5 % simple interest per year after 10 year he received an interest of 50000 how much did he invest​

Answer: 16%

Step-by-step explanation:

168.2 - 145 = 23.2

23.2/145 = 0.16

0.16 as a percent is 16%

The percentage change of the height is A = 16 %

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Christian's height increased by

168.2 - 145 = 23.2 cm

To find the percentage increase, we need to divide the increase by the original height and then multiply by 100:

Percentage increase = (23.2 / 145) x 100%

Percentage increase = 0.16 x 100%

Percentage increase = 16%

Hence , Christian's height increased by 16%

Answer:

16. 29 and 30

17. C. 30 D. 31

Step-by-step explanation:

16. Given the inequality c ≤ $30, which is used to represent the situation, it implies that possible value of c must be equal to $30 or less than $30.

Two possible solutions form the options given would be:

29 and 30.

29 is less than 30, and 30 is equal to 30.

17. The inequality given is b ≥ 30.

This implies that possible solutions will be equal to 30 or greater than 30. It cannot be less than 30.

The solutions that apply would be:

30 (this is equal to 30) and 31 (this is greater than 30).

The remaining options don't satisfy or make the inequality statement true.

Answer:

X= 82°

Step-by-step explanation:

Since we know ∠DAB is 41°, we also know that ∠CBA is 41°, since they must be equal.  This tells us that the bottom angle of that triangle must be 98°, since the sum of all interior angles must equal 180°.  Since this angle is supplementary to x, we know that x must equal 82°.

I found the answer on Quizizz lol, I had the same question for a review :/ I still don't know how they got the answer though

The  volume of Alina’s model in cubic centimeters when the side is 10 so here the volume should be considered as the 400.

Since

The Height of the pyramid is 12 cm

The area of the base should be

[tex]= side^2\\\\= 10^2\\\\= 100[/tex]

Now the volume be

[tex]=1/3 * 100 * 12[/tex]

= 400

Hence, The  volume of Alina’s model in cubic centimeters should be 400.
