Answer:
The measure of ∠D = (Q) = 28.81
Step-by-step explanation:
Tan(Q) = perpendicular/ base
In this case perpendicular is BC and base is DC
BC =25 DC = 45
Tan(Q) = BC/DC
Tan(Q) = 25/ 45
Tan(Q) = 5/ 9
(Q) = tan^ -1 (0.55)
(Q) = 28.81
Answer:
6/infinity
Step-by-step explanation:
There are infinity numbers, and in the list (2, 3, 4, 5, 6, 7) there are 7-2+1=6 numbers. Therefore, the answer is 6/infinity. Very unlikely!
Answer:
7 levels
Step-by-step explanation:
Let x = number of levels
⇒ 5.2 + 7.3x = 60
⇒ 7.3x = 60 - 5.2 = 54.8
⇒ x = 54.8 ÷ 7.3 = 7.5068...
Need to round down to whole complete levels, so number of levels you can play for free = 7
Step 1: find the area of the base
A=l*w = 8.25*5.5 = 45.375
Step 2: find the perimeter of the base
P=2l+2w = 2(8.25) + 2(5.5) = 16.5 + 11 = 27.5
Step 3: find the surface area of the prism
SA=2A+Ph = 2(45.375) + 27.5(4.5) = 90.75 + 123.75 = 214.5
Hope this helps
Answer:
see explaination
Step-by-step explanation:
length (l) = 2x+7
width (b) = 9x
area of rectangle = l×b
=(2x+7)(9x)
=18x^2+63x
perimeter of rectangle = 2(l+b)
=2(2x+7)(9x)
=2(18x^2+63x)
=36x^2+126x
