22/30 = 11/15
7/9 = 14/18
18/54 = 1/3
10/17 = 20/34
A proportion can be set up by using the general formula:
a/b = c/d
ad = bc
Since base angles of an isosceles triangle are congruent the other base angle is also 65. since the three angles together sum to 180 thst leaves 180-65-65=180-130 = 50 degrees for the vertex angle
Tan(30°) = 17/x
x = 17/tan(30°) = 17√3
The hypotenuse of the smaller triangle is as you show, 34.
sin(45°) = 34/y
y = 34/sin(45°) = 34√2
x = 17√3
y = 34√2
Answer:
y = (N/24)x
Step-by-step explanation:
Let N be the no. of announcements per day (in 24 hours)
N/24 per hour
y = (N/24)x
Answer:
The cost of each slice of pizza is $ 14.5
Step-by-step explanation:
Given as :
The combined total of 2 slices and 1 drink cost = $ 31.50
The price of each drink = $ 2.50
Let The number of slices = S
The number of drink = D
According to question
2 × S + 1 × D = $ 31.50
∵ 1 drink cost $ 2.50
So, 2 × S + 1 × D = $ 31.50
Or, 2 × S + 1 × $ 2.50 = $ 31.50
Or, 2 × S = $ 31.50 - $ 2.50
Or , 2 × S = $ 29
∴ S = = $ 14.5
Hence The cost of each slice of pizza is $ 14.5 Answer
