Answer:
35 degrees
Step-by-step explanation:
a triangle has 180 degrees so 70 + 75 + x = 180
solve for it and you get 35 degrees.
Answer:
c.
Step-by-step explanation:
p/4.5 = 6.1
to isolate the variable do the opposite action
p/4.5 = 6.1
as p is divided by 4.5, you must multiply both sides by 4.5
p/4.5 ×4.5 = 6.1 × 4.5
p = 27.45
Answer:
a. 9
b.
c.
d.
Step-by-step explanation:
a. The total number of balls in the bag is
b. Let A denote the event that the 1st chosen ball is orange. Let B denote the event that the 2nd chosen ball is orange.
c. If the first choice is orange, (i.e A occurs) then there are 9 - 1 = 8 balls left in the bag with 3 - 1 = 2 orange balls.
d. Here we are required to compute . We use the fact that
Answer:
126 square feet
Step-by-step explanation:
The formula for the area of a triangle is ...
A = (1/2)bh . . . . . where b is the base length and h is the height
Here, you have a triangular face that has a base of 6 ft and a height of 14 ft. Its area is ...
A = (1/2)(6 ft)(14 ft) = 42 ft^2
The lateral area of the pyramid consists of 3 such triangles, so the lateral area is ...
LA = 3·(42 ft^2) = 126 ft^2
