What is area of trapezium?The area of a trapezium is defined as the number of unit squares that can fit into it . The area of a trapezium can be calculated using the lengths of two of its parallel sides and the distance (height) between them. The formula to calculate the area (A) of a trapezium using base and height is given as,
A = ½ (a + b) h where,
a and b = bases of trapezium, and,
h = height (the perpendicular distance between a and b)
Given
Area of trapezium = 48 [tex]cm^{2}[/tex]
Area of trapezium = [tex]\frac{(AB+DC).h}{2}[/tex]
48 = [tex]\frac{(AB+DC).h}{2}[/tex]
⇒ 48 = [tex]\frac{(5+x).(4)}{2}[/tex]
⇒ 96 = (5+x).4
⇒ 5 + x = [tex]\frac{96}{4}[/tex]
⇒ 5 + x = 24
⇒ x = 24 - 5
⇒ x = 19 cm
Hence, Value of x is 19 cm.

. Jacob and Sadie each got ahead on their skills practices. Jacob completed twelve fewer problems than twice the number Sadie completed. They completed a total of 127 problems. Which system of equations models this situation if Jacob completed j problems & Sadie completed s problems? A) j + s = 127
Answers
Answer:
2s-12=j
S+J=127
Step-by-step explanation:
ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j
. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127

A student claims that the expression “9 times the sum of a number and 13" is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answers
Answer:
No, the student is not correct. The correct expression is 9(n+13).
Step-by-step explanation:
"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.
Answer:
Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

AUB={2,3,5,6,7,9}

A = {3 , 6 , 9}
B = {2,3,5,7}
A ∪ B = { 2,3,5,6,7,9}
(A∪B)' - is set of all elements in universal set that are not in (A∪B)

Answers

Answer:
∠D - no∠E - noDE - yesStep-by-step explanation:
With a single application of the Law of Cosines, you can only find one of an unknown side or an unknown angle. The other three elements in the 4-variable equation must be specified.
However, a single application of the LoC can be used to find DE. Then, knowing the three sides, either of the unknown angles can be found from an additional application of the LoC.
So, the answer is "it depends." It is yes to all if finding DE first is allowed. It is "no" to the angles if they must be found without finding DE first.

The time the bus should arrive at School Road from Hope Street is 08 : 04.
The time of the latest bus that Jo can catch from the Bus Station is 07 00.
The time the bus takes to travel from the bus station to School Road is 14 minutes.
How to find the time ?The table shows that when a bus leaves for School Road from Hope Street, at 07 54, it will arrive on School Road at 08 04.
The time it takes from the bus station to School road is:
= Arrival time at school road - Departure time from Bus station
= 08 04 - 07 50
= 14 minutes
If Jo wants to be in school road at 8 am by the latest, she needs to leave before :
= 8 am - 14 minutes
= 07 46
The only bus leaving before this time is the 0700 bus from the Bus Station.

What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Fixed amount he earns per week = $15
Additional amount added depending on the number of subscription sold = $3
Let x be the number of subscription sold.
Amount earned in a week = 15 + 3x
If amount earned is $90,
15 + 3x = 90
3x = 75
x = 75 / 3 = 25
Hence the number of subscriptions is 25.
