Answer:
so assuming 1 3/4 feet by feet means 1 3/4 feet by 1 foot,
island actual dimentions=1 3/4 feet by 1 foot
scale=1 inch=1 feet
logically, blueprints are smaller so for every real foot, 1 inch is drawn on the scale
so change every foot to inch
so the island on the blueprint=1 3/4 inch by 1 inch
Step-by-step explanation:
this is for 7 not 8 just switch up the numbers
Answer:
down below
Step-by-step explanation:
total distance = sum of velocity * time for both legs of the journey;
let the time taken in air be t
hence time taken in water is 12-t
127 = 16*t + 3(12-t)
127 = 16t + 36 - 3t
127 - 36 = 16t - 3t
91 = 13t
t = 91/13 = 7 seconds
ence time taken in air = 7 seconds
time taken in water is 12 - 7 = 5 seconds
checking; 16*7 + 3*5 = 127 (proven
Answer:
0
Step-by-step explanation:
this is the only answer because if you subtract 2a from both sides you are left with b= since there is nothing there, that makes it 0. There is no way to solve this without b=0. (i think its a TRICK question)
Answer:
The vertex form is: y = 3(x-2)^2 + 7
. The vertex is (2, 7)
Step-by-step explanation:
Write the function: y = 3x^2 - 12x + 11 in vertex form
The vertex form of a quadratic equation is:
y = m(x - a)^2 + b where (a,b) is the vertex
For y = 3x^2 - 12x + 11
Solve for m
y = 3(x^2 - 4x) + 11
Complete the Square:
y = 3(x^2 - 4x + 4) + 11 - 4
y = 3(x - 2)^2 + 7
The vertex then is (2, 7)
Well, I can’t see your choices, but hopefully one looks something like this:
1.25x = 11.25
Or
x = 11.25/1.25
