Answer:
a= 20
b= 169.7
c= 29.71
Step-by-step explanation:
The formula of a triangle is (h*b)/2
a= (5*8)/2
b= to find the height, you can use the pythagorean theorem 18^2 - 6^2 = square root of 288. Which is 12root 2 or 16.97. (16.97*20)/2
c= using the pythagorean theorem- 11^2 = 7^2 - c^2 = square root 73, or 6root 2, or 8.49. (8.49* 7)/2
Answer:
cost when 400 miles is driven is $143.
Step-by-step explanation:
Model for cost calculation: C=0.32m + 15
We have to find cost when no. of miles driven is 400.
To find that cost we need to plug 400 in place of m.
C=0.32m + 15
=> c = 0.32*400 + 15
=> c = 128 + 15 = 143
Thus, cost when 400 miles is driven is $143.
Answer:
Store A sells the watch $0.50 less than B
Step-by-step explanation:
Store A: 5% of 50 = $2.50 Therefore, store A sells for $47.50
Store B: 20% of 60 = $12.00 Therefore, store B sells for $48.00
Answer:
d = 48.03 feet
Step-by-step explanation:
Given that,
The maximum angle for a wheelchair ramp entering a business at 4.76 degrees.
We need to find the horizontal distance needed to accomidate a ramp that goes up to a door 4 feet of the ground.
We can solve it using trigonometry.

Where
h is height
d is the angle of elevation

So, the horizontal distance is equal to 48.03 feet.
