Answer:
131.25
Step-by-step explanation:
There are 3 trapezoids that you need to find its area, all the areas are the same.
Area of trapezoid:
A=(a+b)/2*h
a = 20
b = 15
h = (20-15)/2 = 5/2
A = (20+15)/2*5/2
A = 43.75
3A (3 gardens) = 131.25
Let d be distance travelled when they are level , and t = time that nora took to get level with mason
for Nora
6 = d/t
d = 6t
for Mason
5 = d / (t + 35)
d = 5 ( t + 350
so 6t = 5(t + 35)
solve for t
Answer:
8 * 7
Explanation:
When you count the squares along the area, you will find that the base is 8 units, and the height is 7 units. The area of a square is equal to base * height, so the correct answer is 8 * 7.
Answer:
This test batch can be chosen in 2380 ways
Step-by-step explanation:
The order in which the batteries are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In how many ways can this test batch be chosen?
4 batteries from a set of 17. So
This test batch can be chosen in 2380 ways
Line
Angle
Line Segment
Point
