Answer:
38 square inches
Step-by-step explanation:
The figure is a quadrilateral with one pair of parallel sides. That means it is a trapezoid, so the area formula for a trapezoid is applicable.
A = (1/2)(b1 +b2)h
The two parallel bases are 7 in and 12 in. The height is the perpendicular distance between them, 4 in. So, the area is ...
A = (1/2)(7 in +12 in)(4 in) = (1/2)(19 in)(4 in)
A = 38 in²
The area of the trapezoid is 38 square inches.
(i) the number of students who passed in the first and in the second division
76+95=171 students
(ii) The ratio of the number of students who passed in the first second and in the third division.
RATIO is 4:5:(25/19) or 4:5: 1.3157894…….
225-29=196 (29students failed)
196-25=171. (Subtract 25 students from the 3rd division)
4x+5x= 171 (171 students from 1st and second division)
9x=171
X=19
4x19=76 5x19= 95 1.31578.....x19= 25
Step 1
Write out the system of equations
Step 2
Find the value of one pound of type A coffee, x
Therefore the answer will be;
The pounds of type B coffee she used is 64pounds
The pounds of type A coffee she used is 84 pounds
-136 = 8m - 8
-136 + 8 = 8m
-128/8 = m
-16 = m
M = -16
