Step-by-step explanation:
let breath be b
area = length × breath
155 = 13 × b
b= 155/13
b= 11.92

Answer:
0,5X + (-2), but you have to solve it... I give you the equation.
Step-by-step explanation:
In part A you have to find the equation of the line, so you do end - origin and you'll find m. I can only help you with the first one.
so:
(8,2) and (10,3)
(10-8,3-2) = (2,1)
V2/V1= 1/2= 0,5=m (slope of the line)
y= mx+n (change y, x and m with the ones above)
2= 8·0,5+n
2= 4+n
n= 2-4=-2
the equation is: 0,5X + (-2) and then you just have to change x in both equations, the second one is the h(x) adn it will give you the answer to A.
I hope I'm being helpful..!!!
Answer:
C
Step-by-step explanation:
The figure consists of a semicircle of radius 6 m, and a triangle with base of 12 m and height of 5 m. The base of the triangle is 12 m since it has the length of the diameter of the circle, or twice the 6-m radius.
A = area of semicircle + area of triangle
A = (1/2)πr² + bh/2
A = (1/2)π × (6 m)² + (12 m)(5 m)/2
A = (18π + 30) m²
Answer: C
Answer:
Step-by-step explanation:
Ray hired sun and peter to help him move.
Let h represent the number of hours that each of them worked.
Let y represent Ray's total cost for hiring Sun and Peter for h hours.
Sun charged a $20 flat fee and $30 per hour. The total amount that Sun charges would be
20 + 30h
Peter charged $25 per hour. The total amount that Peter charges would be
25h
An expression for Ray's total cost if Sun and Peter each work h hours would be
y = 20 + 30h + 25h
y = 20 + 55h
