Answer:
129.5 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h(a + b)
where h is the height and a, b the parallel bases
Here h = 7, a = 15 and b = 22 , thus
A = × 7 × (15 + 22)
= 0.5 × 7 × 37
= 129.5
Answer:
Answer: Domain is the set of all possible input for which the relation is defined. In this relation x is the variable that defines all inputs of the relation and y is the variable that defines all outputs of the relation. In the ordered pairs, the set of x-coordinates is called domain of the relation.

Answer:
28
Step-by-step explanation:
Volume = Area of cross section x length
= (1/2 x 2 x 4) x 7
= 28
Answer:
The number of students who received the paint=5 students
Step-by-step explanation:
Step 1: Determine amount given to each student
Quantity per student=1/7 gallon per student
Step 2: Determine the total amount of paint Mrs. Jennings had
The total quantity of paint Mrs. Jennings is:
Initial quantity of paint=5/7 gallon
Step 3: Calculate number of students who received the paint
The number of students who received the paint can be expressed as;
Initial quantity of paint=Quantity per student×number of students
where;
Initial quantity of paint=5/7 gallons
Quantity per student=1/7 gallons
number of students=n
replacing;
5/7=(1/7)×n
n=(5/7)×7
n=5
The number of students who received the paint=5 students
