Answer:
The value of x is 10.5 units.
Step-by-step explanation:
Given:
ABCD is a parallelogram.
AB =
BC =
CD =
We need to find the value of x.
Now the Definition of Parallelogram states that;
"A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length and the opposite angles are equal in measure."
Hence from Above definition we can say that;
since these are the opposite sides of parallelogram.
Now Substituting the given values we get;
Now solving the equation we get;
Combining the like terms first.
Now using addition and subtraction property of equality we get;
Now using Division Property we will divide 2 on both side we get;
Hence the value of x is 10.5 units.
If Kalon can complete the job in 4 hours, he has completed 1 5/7 over 4 of the job if he works together with Marna. Letting x be the number of hours it will take Marna to work alone, she has completed 1 5/7 over x of the job. The amounts of job they have done should be equal to 1.
(1 5/7 / 4) + ( 1 5/7 / x ) = 1
The value of x is 3. So, Marna can clean the chimney in 3 hours.
Answer:
Step-by-step explanation:
tan Ф = opposite side divided by the adjacent side
tan Ф = opp/adj in your problem Ф is x
tan x = 4/9
x = arctan (4/9) on your calculator arctan is might look like inverse tan
or you might have to use the 2nd (second) button and then tan
x = inverse tan (0.44444 repeating) try it on your own calculator
= 23.962488974578183 rounds up to 24.0
= 24.0
The correct answer is C (3x+7)(3x+7)
It should be 0.08
Explanation: There are six ways to get a 7 and two ways to get an 11 on two dice, and so there are 36 – 8 = 28 ways to get anything else. Therefore, P(no 7 or 11) = P(always getting something else) = (28/36)10
