Answer:
Hope the below answer is easy to understand
Step-by-step explanation:
1) Given the four angles of a quadrilateral are in the ratio 1:2:3:4
Then Let the angles are x,2x,3x and 4x
We know that total of four angles of a quadrilateral =360 °
∴x+2x+3x+4x=360 °
⇒10x=360 °
⇒x=36 °
hence the measures of angles are 36 ° ,72 ° ,108 ° ,144 °
2) Measure of interior angle of a polygon= 180°.
Sides of the polygon = 7 sides
Therefore,
Interior angle of the polygon having 7 sides = 180/7 = 25 5⁄7°
The answer is <span>8,686,308,783.</span>
To calculate this, we will use the equation for exponential function:

y - the future population
x - the current population
r - the rate of increasing the population
n - the number of years
It is given:
x = 6,486,915,022
r = 1.4% = 0.014
n = 2026 - 2005 = 21
Therefore:
Answer: 2.5, 17.5
Step-by-step explanation: I'm kinda confused at what those big blue things with numbers are... but im guessing that's just used to indicate the missing values. So 10/4 = 2.5, meaning the ration is 2.5 pounds per week. So 1 week is 2.5 pounds, and 7 weeks is 2.5*7 = 17.5
Answer: 100
Step-by-step explanation:
4(5)^5
4 x 5^5
4 x 25
100
(5) you need to subtract 19 from 25 or
9 plus x the number to get 14
