Answer:
The length of the longer base he 35 units
Step-by-step explanation:
Here, we want to find the length of the longer base of the trapezoid
Mathematically, we can find the area using the formula;
1/2( a + b) h
where a is the shorter base
b is the longer base
h is the height
Let the shorter base be x
The other base is 5 times this length and that makes 5 * x = 5x
Height is the average of both bases;
(x + 5x)/2 = 6x/2 = 3x
Substituting these in the formula, we have ;
1/2(x + 5x)3x = 441
3x(6x) = 882
18x^2 = 882
x^2 = 882/18
x^2 = 49
x^2 = 7^2
x = 7
But the longer base is 5x and that will be 5 * 7 = 35 units
Answer:
D 18%
Step-by-step explanation:
18/100 = 18%so D is the answer
Thats the same thing as 0.3 x 10
when mulitplying by 10, 100, 1000, etc.
what i do is i move the decimal place over how many zeros there are so there is one zero and that means you need to move the decimal place over one space to the right so the answer is
3
Answer:
13.1
Step-by-step explanation:
Finding mean in data set is finding the average. The way to find the average is by adding all the data in the set (the # of movies watched), then divide them by how many numbers are in the data set (7).
16+13+19+16+8+10+10=92
After you add the data in the set, you have to divide it by the pieces of data there is.
So 92/7=
13.1428571

If you round 13.142...to the nearest tenth, you get <u>13.1.</u>
