18.5 would be the answer and here’s my work
Answer:dd and subtract the remaining numbers in the math problem. The sum will be the result of adding numbers, while the difference will be the result of subtracting them. For instance, in the math problem 4 + 3 - 5, the sum of 4 and 3 will be 7, and the difference between 7 and 5 will be 2.
Step-by-step explanation:
Answer:
I think the answer would be B.
The expression we have is:
And we are given some values for x and y:
The first step will be to substitute the given values into the expression:
The next step is to solve 4^2 which is equal to 16:
And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:
Solving this final multiplication we get the result:
Answer: 512
Part A)
we know that
<span>scale ----------> inch/4 feet=0.25 in/ft
</span>[scale]=[scale drawing]/[actual]
[actual]=[scale drawing]/[scale]
for <span>length --------> 4 1/2 in ---------> 4.5 in (</span>scale drawing)
[actual]=[4.5]/[0.25]=18 ft
for <span>width ---------> 3 3/8 in</span> ---> (3*8+3)/8 ---> 27/8 in (scale drawing)
[actual]=[27/8]/[0.25]=13.5 ft
the answer part A is
length actual <span>kitchen floor is 18 ft
</span>width actual kitchen floor is 13.5 ft
Part B)
the area of one square in the actual=(1/2)*(1/2)=0.25 ft²
total area gray tiles=0.25*14=3.5 ft²
total area white tiles=0.25*10=2.5 ft²
find <span>how many tiles 2 in by 2 in of each color will he need
1ft</span>²-------------> 144 in²
gray tiles
3.5 ft²---------------> 3.5*144=504 in²
[tiles 2 in by 2 in gray]=504/(2*2)=126 gray tiles
white tiles
2.5 ft²---------------> 2.5*144=360 in²
[tiles 2 in by 2 in white]=360/(2*2)=90 white tiles
the answer Part B) is
126 gray tiles
90 white tiles
