Find the value of x for which line a is parallel to line b. (21)

Mathematics
1 answer:
Romashka [77]3 years ago

X is 20 degrees. Since it says that lines a and b are parallel and angles four and five are right next to each other, it means that when you add the two of them together you’ll get 180. Since it’s replaced with variables with coefficients, add the coefficients to get 9 and divide 180/9 to get 20. 20 is the value for x which is your answer

What are two consecutive integers such that two times the first is 43 more than the second
Virty [35]
You can think of two consecutive integers as n and n+1, and hence create an equation:
2n = (n + 1) + 43 = n + 44
Rearranging the equation by subtracting n from both sides
n = 44
Hence, your two consecutive integers are n and n+1 i.e. 44 and 45
You can check this: 44•2 = 88 = 45+43

If the original bill is $22.50, what will be the final bill after a 15% tip is paid? round to the nearest cent
Studentka2010 [4]
For this case what you should do is take 15% of 22.50 and add it to the original price. We have then:
 ((15) / (100)) * (22.50) = 3.375
 Then, we add to the original price:
 22.50 + 3.375 = 25.875
 round to the nearest cent
 25.88

 C.$25.88

The glass container is filled to a height of 2.25 inches. What percent of the container is filled with sand?
Makovka662 [10]
The complete question in the attached figure

Part A) How much sand is currently in the container?
[sand  currently in the container]=(5)*(4 1/2)*(2.25)-----> (5)*(4.5)*(2.25)
[sand  currently in the container]=50.625 in³

the answer Part a) is 50.625 in³

Part B) How much more sand could the container hold before?
[sand could the container hold before]=[5*4.5*3]-[50.625]
[sand could the container hold before]=[67.5]-[50.625]------> 16.875 in³

the answer Part B) is 16.875 in³

Part C) What percent of the container is filled with sand?
the volume of container is [5*4.5*3]=67.5 in³
the volume filled with sand=50.625 in³
therefore
if 100%----------------> 67.5 in³
 X---------------------> 50.625 in³
X=(50.625*100)/67.5=75 %

the answer Part C) is 75%
