Answer:
Part 15) Asia is [tex]1\frac{14}{29}[/tex] times greater than Africa
Part 16) [tex]\$469[/tex]
Part 17) [tex]\$3,060[/tex]
Step-by-step explanation:
Part 15)
Let
x------> Asia's area
y-----> Africa's area
we have
[tex]x=17,200,000\ mi^{2}[/tex]
[tex]y=11,600,000\ mi^{2}[/tex]
Divide x by y
[tex]\frac{x}{y} =\frac{17,200,000}{11,600,000}=\frac{43}{29}=\frac{29}{29}+\frac{14}{29}=1\frac{14}{29}[/tex]
therefore
Asia is [tex]1\frac{14}{29}[/tex] times greater than Africa
Part 16)
Let
x----> amount of money remained in the account
we know that
[tex]x=\$1,679-(\$625+\$546+\$39)=\$469[/tex]
Part 17)
step 1
Find the area of the hallway
[tex]A=18*17=306\ ft^{2}[/tex]
step 2
To find the cost multiply the total area by [tex]10\frac{\$}{ft^{2}}[/tex]
so
[tex]306\ ft^{2}*10\frac{\$}{ft^{2}}=\$3,060[/tex]
