<u>Probability of selecting 1 red and 2 yellow apples</u> = 45 / 84 = 0.53
Answer:
x = -1/2
Step-by-step explanation:
multiply the -4 to all in parentheses
-4(3-2x) +2x =2x -8
-12+8x +2x =2x-8
isolate x by moving whole numbers to other side of equal sign and x to the other side
8x +2x -2x = -8+12
8x = -4
/8
divide by 8 to isolate x
x= -4/8
simplify
x= -1/2
Answer:
£495 million
Step-by-step explanation:
To find out the total cost of the land, we need to first calculate the area of the land.
Step 1: Find area of right angled triangle ADC
AD = 5 km,
DC = 12 km
Area of the right triangle = ½*a*b
a = 5km
b = 12km
Area = ½*5*12
= 5*6
Area of ADC = 30 km²
Step 2: Find the area of triangle ABC
First, let's find the length of AC using Pythagorean theorem
AC² = AD² + DC²
AC² = 5² + 12² = 25 + 144
AC = √169
AC = 13km
Area of ∆ABC = ½*AB*AC*sin(30°)
= ½*6*13*0.5
= 3*13*0.5
Area of ∆ABC = 19.5 km²
Total area of the land = area of ∆ADC + ∆ABC = 30 + 19.5 = 49.5 km²
Step 3: calculate how much the land costs
If the land costs £10 million per km²,
Cost of 49.5 km² = 49.5 × 10 = £495 million
