Answer: 75 feet
Step-by-step explanation:
From the question, we are informed that two similar rectangles have a scale factor of 3:2 and that the perimeter of the small rectangle is 50 feet.
The perimeter of the large rectangle measured in feet will be calculated as:
= 3/2 × 50
= 150/2
= 75 feet
Answer: x= 3
Step-by-step explanation:
2x + 5 = 11
2x = 6
x = 3
1.
the x value of the vertex in form
ax^2+bx+c=y
is
-b/2a
so
-2x^2+8x-18
x value of vertex is
-8/(2*-2)=-8/-4=2
plug it in to get y value
-2(2)^2+8(2)-18
-2(4)+16-18
-8-2
-10
vertex is at (2,-10)
or you could complete the square to get into y=a(x-h)^2+k, where the vertex is (h,k)
so as follows
y=(-2x^2+8x)-18
y=-2(x^2-4x)-18
y=-2(x^2-4x+4-4)-18
y=-2((x-2)^2-4)-18
y=-2(x-2)^2+8-18
y=-2(x-2)^2-10
vertex is (2,-10)
5.
vertex is the time where the speed is the highest
at about t=10, the speed is at its max
Answer:
90 men
Step-by-step explanation:
just keep the ratio constant
3:7
equals 10 parts
300/10=30
3*30:7*30
90 men and 210 women
hope this helps!!! :)
