Answer: option B is correct
Step-by-step explanation:
The formula for determining the area of cross section of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of The bases are the 2 sides of the trapezoid which are parallel with one another.
h represents the height of the trapezoid.
From the information given,
a = h1 = 11 inches
b = h2 = 15 inches
If It has an area of 52 inches² , then
52 = 1/2(11 + 15)h
Cross multiplying by 2, it becomes
52 × 2 = (11 + 15)h
104 = 26h
h = 104/26 = 4 inches
We need to find the area of the package
10 times 12 times 1 is 120
the package is 120 in squared
each cube that holds one ring is 1 inch and there are 120 inches
so the jewelry store reveiced 120 rings.
the explaination. to find how many rings are in a package we need to find the volume of that package. Then once we have that we need to find how many of the cubes can fit into that area.
To find how many pennies are in the bigger jar if the smaller jar contains 133 pennies and the bigger has 1 2/7 of it, we have to multiply 133 by 1 2/7.
133 * 1 2/7 =
= 133 * 9/7 =
= 19 * 9 =
= 171
Answer: There are 171 pennies in the bigger jar.
