Answer:
x = 3.6
Step-by-step explanation:
It can be helpful to write down corresponding sides and their measures.
AB = 5, PQ = 6
BC = 3, QR = x
CD = 2, RS = 2.4
DA = 4, SP = 4.8
Then you can look for easy ways to find x. You can tell from this table that all of the values in PQRS are 6/5 = 1.2 times the corresponding values in ABCD.
Then ...
QR = 1.2×BC = 1.2×3
QR = x = 3.6
_____
Other ways you can figure x are ...
x/BC = PQ/AB
x = (BC)(PQ/AB) = 3(6/5) = 3.6 . . . . the method we used
__
x/RS = BC/CD
x = 2.4(3/2) = 3.6
__
x/SP = BC/DA
x = 4.8(3/4) = 3.6
The relative frequency that the traffic lights will show GREEN at road works is 0.7. Estimate how many times they would be RED over the next 40 journeys?
Answer:
28 reds are expected over the next 40 journeys
Step-by-step explanation:
Here, we want to get the number of reds in the next 40 journeys
From the question, we have that the relative frequency is 0.7
Thus, for the number of reds, we have to multiply the relative frequency by the number of journeys
We have this as;
40 * 0.7 = 28
Mark works 24 hours a week and earns £11.63.
Calculate Mark's weekly basic pay and then find his annual salary
Weekly pay = amount per hour x number of hours:
24 x 11.63 = 279.12
Annual salary = weekly pay x 52 weeks:
279.12 x 52 = 14,514.24

find the value of x
please help
Answer:
Here we can see that two lines are intersecting so that the angles formed will be vertically opposite angles,
Thus, the value of both angles will be equal
i.e., x+3 = 84
⇒ x = 84 - 3
⇒ x = 81
Thus the value of x is 81

What is the value of y in the parallelogram below?
5y"
654
O A. 110
O B. 60
O c. 13
D. 23
Answer:
D. 23
Step-by-step explanation:
5y = [360 - (65 x 2)] / 2
5y = [360 - 130] / 2
5y = 230 / 2
5y = 115
y = 23
Hope that helps!
Explain why this common mistake is wrong. Many people might say that (2, 4) is an intercept of the equation 5x + 2y = 18.
Answer:
Step-by-step explanation:
(2,4) is point lying on the line represented by 5x + 2y = 18.
They are not intercepts.
x-intercept is point where the line crosses the x-axis and so, y-co ordinate at x-intercept is 0.
y-intercept is point where the line crosses they-axis and so,x-co ordinate at y-intercept is 0.
5x + 2y = 18
To find x-intercept, put y = 0 in the equation
5x = 18
x = 18/5
x = 3.6
To find y-intercept, put x = 0 in the equation
2y = 18
y = 18/2
y = 9
x-intercept : (3.6 , 0)
y-intercept :(0, 9)

Answer:
Z = 13
Step-by-step explanation:
Both of the angles should equal 90.
2z + 5 + 5z - 6 = 7z - 1
7z - 1 = 90
7z - 1 + 1 = 90 + 1
7z = 91
7z ÷ 7 = 91 ÷ 7
Z = 13

Answer:
sin 2 ( x ) ⋅ sin 2 ( x ) cos 2 ( x ) → sin 2 ( x ) tan 2 ( x )
Step-by-step explanation:
Assuming tan = 2 ( x ) − sin 2 ( x ) = tan 2 ( x ) sin 2 ( x ) ,
tart off by rewriting tan 2 ( x ) in to its sin ( x ) and cos ( x ) components.
sin 2 ( x ) cos 2 ( x ) − sin 2 ( x )
Next find a common denominator
(LCD:
cos 2 ( x )⋅ 1 ) sin 2( x ) cos 2 ( x ) ⋅ ( 1 1 ) − sin 2 ( x ) ⋅ cos 2 ( x ) cos 2 ( x ) → sin 2 ( x ) cos 2 ( x ) − sin 2 ( x ) cos 2 ( x ) cos 2 ( x )
Combine in to a single fraction and factor out a
sin 2 ( x) . sin 2 ( x ) − sin 2 ( x ) cos 2 ( x ) cos 2 ( x ) → sin 2 ( x) ⋅ sin 2 ( x ) cos 2 ( x )
Finally just rewrite sin 2 ( x ) ⋅ sin 2 ( x ) cos 2 ( x ) → sin 2 ( x ) tan 2 ( x )

Answer:
The excluded value is x = 5/6
Step-by-step explanation:
Here, we want to calculate the excluded value
The excluded value is simply the value of x that will make the denominator of the fraction equals zero
We have this as;
6x -5 = 0
6x = 5
x = 5/6

answer this question and show work or have an explanation.
Answer:
70
Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.
Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.
40 + 2x = 180. Subtract 40 from both sides.
2x = 140. Divide both sides by 2.
X = 70
