Answer:
75 + 25d > 250
d > 7
Step-by-step explanation:
Number of signatures needed : > 250
Amount of signatures ready = 75
Exoected number of signatures per day = 25
Number of days, d, needed signatures will be collected ;
Number of ready signatures + (expected number of signatures per day * number of days) > number of signatures needed
Mathematically,
75 + 25d > 250
25d > 250 - 75
25d > 175
d > 175 / 25
d > 7
Letter b. (2,5) is the only one that when plugged into the inequality above still makes the inequality true because 7<=7 and 5>2
Step-by-Step Explanation:
a) Rename
as a percent
![\frac{7}{20}\times 100\\\\=7\times 5\\\\=35\%](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B20%7D%5Ctimes%20100%5C%5C%5C%5C%3D7%5Ctimes%205%5C%5C%5C%5C%3D35%5C%25)
b) Rename .245 as a percent
![.245\times 100\\\\=\frac{245}{1000}\times 100\\\\=24.5\%](https://tex.z-dn.net/?f=.245%5Ctimes%20100%5C%5C%5C%5C%3D%5Cfrac%7B245%7D%7B1000%7D%5Ctimes%20100%5C%5C%5C%5C%3D24.5%5C%25)
c) Rename 28% as a fraction and a decimal in simplest form
![28\%=\frac{28}{100}=\frac{7}{4}\text{ as a fraction}\\\\\frac{7}{4}=1.75\text{ as a decimal}](https://tex.z-dn.net/?f=28%5C%25%3D%5Cfrac%7B28%7D%7B100%7D%3D%5Cfrac%7B7%7D%7B4%7D%5Ctext%7B%20as%20a%20fraction%7D%5C%5C%5C%5C%5Cfrac%7B7%7D%7B4%7D%3D1.75%5Ctext%7B%20as%20a%20decimal%7D)
d) Put .367,36.5%,
in order least to greatest.
![\text{ First we put change all into percent form}\\\\.367\times 100=\frac{367}{1000}\times 100=36.7\%\\\\\frac{9}{25}\times 100=9\times 4=36\%](https://tex.z-dn.net/?f=%5Ctext%7B%20First%20we%20put%20change%20all%20into%20percent%20form%7D%5C%5C%5C%5C.367%5Ctimes%20100%3D%5Cfrac%7B367%7D%7B1000%7D%5Ctimes%20100%3D36.7%5C%25%5C%5C%5C%5C%5Cfrac%7B9%7D%7B25%7D%5Ctimes%20100%3D9%5Ctimes%204%3D36%5C%25)
Now, we have 36.7%, 36.5%, 36%
We have write it in ascending order i.e. least to greatest ,
Here it is,
36%, 36.5%, 36.7%
![\frac{9}{25},36.5\%\ and\ .367](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B25%7D%2C36.5%5C%25%5C%20and%5C%20.367)
Answer:
153.938 ft²
Step-by-step explanation:
πr² (area of a circle where r is the radius
π(7)²
π(49)
π(49)≈153.938
