4 acres / 2/3 acre/lot
= 4 acres * 3/2 lot/acre = ?
3 m is to 5.6 l as x is to 8 l
3 / 5.6 = x / 8
3/5.6 * 8 = x = 4.29 m
Just add all of the sides 28 + 22 + 28 + 22 =
Ooops...missed the semicircle....see Omi 's answer below!
51 coins
x = #dimes amount = .10 x
51-x = # quarters amount = .25 (51-x) added together = 10.35
.10x + .25(51-x) = 10.35 solve for x which is the number of dimes. then #quarters = 51-x
When you start walking, your friend has been walking 5 minutes (1/12 hr) at 3 m/hr
Rate x time = distance
3 m/hr x 1/12/hr = 3/12 mile = 1/4 mile
Total solution will be 500 ml
500 ml of 60% = 500 (.6) = 300 ml of 100%
75 % solution is x .75 x is amount
25 % solution .25 (300-x)
.75x + .25 (300 - x) = 300 Solve for 'x' = amount of 75% solution to use
12 c 4 = 495 11 c 4 = 330
You will need 12
Area of triangle = 1/2 b h in a 45 90 45 triangle b and h are the same value
1/2 b^2 =32
b^2 =64
b = 8 she will nee two 8 ft pieces = 16 ft PLUS the lenght of the hypotenuse
sqrt (8^2 + 8^2) = hyp = 11.31 ft (via pythag theorem)
11.31 + 16 = 27.3 ft of fence ~~ 27 ft
1 1/3 is to 1/5 as x is to 1
4/3 / 1/5 = x / 1
4/3 * 5 = x
20/3 = x
x = 6 2/3 cups wheat cereal
This is in Quadrant 4 cos and secant will be positive
sqrt(10^2 + (-4)^2 ) = sqrt116 = 2 sqrt 29 (hypotenuse)
Sec = 1/cos = hyp/adj = 2 sqrt 29 / 10 sqrt29/5
