In this case we have 1/4 are green then (1/4) * 100 = 25. Then, 2/5 are yellow then (2/5) * 100 = 40. Therefore if the total number of skitles is 100, then the red skittles will be 100-40-25 = 35. There are 35 red skitles.
Answer:
13cm
Step-by-step explanation:
P=2l+2w
56=2(15)+2w
56=30+2w
26=2w
w=13
Answer:
1200feet
Step-by-step explanation:
Given the the road's curve elevation modeled by the equation
y = 0.00005x^2 - 0.06x,
x is the horizontal distance in feet between the points where the road is at sea level and;
y is the elevation
The elevation the road is equal to sea level when y = 0
Substitute y = 0 into the equation and calculate x;
0 = 0.00005x^2 - 0.06x
0.06x = 0.00005x^2
0.06 = 0.00005x
x = 0.06/0.00005
x = 1200 ft
Hence they will place the stop sign at a horizontal distance of 1200feet
Answer:
f(x) = (x+4)^2 / 2
Step-by-step explanation:
To make a horizontal shift to the left 4 units, we just need to substitute the value of x for 'x+4', then we will have:
f(x) = (x+4)^2
Then, to make a vertical shrink of 1/2, we just need to multiply the function (the new function after being shifted horizontally to the left) by 1/2, then we will have:
f(x) = (x+4)^2 / 2
Answer:
x = -10 and x = 9
Step-by-step explanation:
-x = 10 <- divide -1 on both sides: -1x / -1 and 10 / -1.. you get -10 = x
repeat with -x = -9 <- divide -1 on both sides: -1x / -1 and -9 / -1.. you get 9 = x
