Dimensions of a rectangular deck = [tex]40[/tex] feet by [tex]3[/tex] yards
Width of the deck is in yards, so convert it into feet.
Since, [tex]\frac{1}{3}[/tex] yards = 1 foot
Therefore, 1 yard = [tex]3[/tex] feet
And [tex]3[/tex] yards = [tex]3\times 3[/tex] feet
= [tex]9[/tex] feet
Therefore, dimensions of the rectangular deck = [tex]40[/tex] feet by [tex]9[/tex] feet
Area of the deck = Length × Width
= [tex]40\times 9[/tex]
= [tex]360[/tex] square feet
∵ [tex]50[/tex] square feet of deck is stained by number of cans = 1
∴ 1 square feet will be stained by number of cans = [tex]\frac{1}{50}[/tex]
∴ [tex]360[/tex] square feet will be stained by cans = [tex]\frac{360}{50}[/tex] = [tex]7.2[/tex]
We can not purchase can in fractions or parts.
Therefore, number of cans to be purchased = [tex]8[/tex]
Cost of waterproof stain per can = $[tex]19.99[/tex] plus [tex]8[/tex]% sales tax
Therefore, actual cost of 1 can to be paid for the waterproof stain
= [tex](19.99 + 19.99\times \frac{8}{100})[/tex]
= [tex]19.99+1.5992[/tex]
= $[tex]21.5892[/tex]
Cost of [tex]8[/tex] cans = [tex]21.5892\times 8[/tex]
= $[tex]172.71[/tex]
I have paid $[tex]150[/tex] to the cashier.
Therefore, additional money to be paid = [tex]172.71-150[/tex]
= $[tex]22.71[/tex]

An alloy is made of copper and iron by weight. 42% of it is copper and the rest is iron. If the alloy weights 55 kg, find the weight of copper and iron
Answer:
percent of iron in alloy= 100-42 = 58%
weight of the iron = 55×58÷100= 31.9
weight of iron= 31.9 kg
weight of copper= 55-31.9=23.1
weight of copper = 23.1
Step-by-step explanation:
[ I'm not sure but I think this is right ]
Answer: copper = 23.1 kg
iron = 31.9 kg
Step-by-step explanation:
copper = 42% of 55
= 42/100 * 55
= 42/20 * 11
= 21/10 * 11
= 231/10
= 23.1 kg
so iron = 100% - 42%
= 58%
so
58% of 55
= 58/100 * 55
= 58/20 * 11
=31.9 kg

A man is paid $1500 salary. He spends 20% of the salary for his kids education, 35% for food, 15% for miscellaneous and he saves the rest. How much money does he save?
Answer:
450
Step-by-step explanation:
The total is 100 %
20% + 35% +15% = 70%
100-70 = 30
He saves 30%
1500 * 30%
1500 *.30
450
A man is paid $1500 salary. He spends 20% of the salary for his kids education, 35% for food, 15% for miscellaneous and he saves the rest. How much money does he save?
S O L U T I O N :Total Income = $ 1500
According to the question,
He spends 20% to his kids education
He spends 35% for food
He spends 15% for miscellaneous
Out of total income he spends 20% on kids education
So, amount spent on kids education = 20% of $1500
Amount = 20/100 × $1500
Amount = $300
Hence, money spent on his kids education is $300
35% is spent on food
Money spent on food = 35% of $1500
Money spent = 35/100 × $1500
Money spent = $525
Hence, money spent on food is $525
15% is spent on miscellaneous
Money spent on miscellaneous = 15% of $1500
Money spent = 15/100 × $1500
Money spent = $225
Hence, money spent on miscellaneous is $225
Now, adding all the three we get
$300 + $525 + $225
$825 + $225
$1050
Total money spent = $1050
Remaining money = $1500 - $1050 = $450
Remaining amount left with him is $450How can i solve this?

f(x)=x^2-6x
g(x)= √x
Evaluate f(g(25)) = ???
Answer:
f(g(25)) = -5
Step-by-step explanation:
You have to put 25 in place of x in g, and after, you take the result and put in place of x in f:
g(5) = √25 = 5
f(5) = 5^2 -6•5
f(5) = 25 -30
f(5) = -5

yancy made a 1:14 scale model airplane. the model airplane's tail is 5.7 inches long what is the length of the actual airplane tail its modeled after? round to two decimals
Scale factor used by Nancy for the model of an airplane = 1 : 14
Length of the tail of the airplane = 5.7 inches
Scale factor is defined by the expression,
Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]
By substituting the dimension of the model in the expression,
[tex]\frac{1}{14}=\frac{5.7}{\text{Dimension of the original}}[/tex]
