To solve this question, we just need to insert 12 into the m position of each question and see if the equation holds true.
a. 4m = 40
4(12) = 40
48 = 40
48 obviously does not equal 40, so it is not choice A.
b. m + 20 = 42
12 + 20 = 42
32 = 42
Again, 32 isn't the same as 42, so not choice B either.
c. 4m = 48
4(12) = 48
48 = 48
It looks like this one is true, but let's solve D also just to make sure.
d. m - 4 = 9
12 - 4 = 9
8 = 9
This is false, since 8 does not equal 9.
Therefore, choice C (4m = 48) is the correct answer.
Hope that helped! =)
We know how wide the billboard will be. Therefore, to know how much the original image should be enlarged, you must divide the final width of the billboard between the current width of the invoice.
We know both data, then we perform the operation:
48 feet /6.14 inches = 7.81 feet / inches
.
Therefore the correct answer is option D. 1″ = 7.81′
For the bill to cover the billboard, the bill must be expanded by a factor of 7.81 feet long per inch long that has the original image.
Answer:
The % Alicia speed walking is 125 % of average walking
Step-by-step explanation:
Given as :
Distance cover by Alicia while walking = 4 miles
Time taken = 1 hour
So, Speed of Alicia while walking =
Or, S 1 =
I.e S 1 = 4 mph
And
Distance cover by Alicia while speed walk = 5 miles
Time Taken = 1 hour
So, Speed of Alicia while speed walking =
Or, S 2 =
I.e S 2 = 5 mph
Or, % Rate =
×100 = 125
Hence The % Alicia speed walking is 125 % of average walking Answer
