Answer:
AB = 23.4 inches
Step-by-step explanation:
If the diameter of the wheel is 25 inches, we have that its radius is 25/2 = 12.5 inches.
If we draw a radius to the bottom of the wheel and a radius to point A, we have a triangle where we can use Pythagoras' formula:
(see image attached for better understanding)
r^2 = (r-8.1)^2 + (AB/2)^2
12.5^2 = 4.4^2 + AB^2/4
156.25 = 19.36 + AB^2/4
AB^2/4 = 136.89
AB^2 = 547.56
AB = 23.4 inches
The equation that can be used to determine the time for each leg is D. 600t = 480(18 – t)
<h3>How to calculate the equation?</h3>
Speed on going ,= 600 miles per hour.
Speed on return = 480 miles per hour
Time on returning = 18 - t
Distance = Speed × Time
Distance = 480(18 - t)
The equation that can be used to determine the time for each leg will be:
600t = 480(18 – t)

Since angles A and C are equivalent, then angles B and D must also be equivalent. So if
angle B = angle D then...
7x + 15 = 8x
Now we just solve for x
7x + 15 = 8x
15 = 8x - 7x
15 = x
We Can check to see if it is correct by substituting 15 in for x in the equation..
7x + 15 = 8x
7 (15)+15 = 8 (15)
105 +15 = 120
120 = 120
It checks! angles B and D = 120 degrees

Answer:
200g of sugar, 600g of flour, 400g of butter
Step-by-step explanation:
50g sugar = 15 biscuits
3 x 50g = flour --) 150g = flour
2 x 50g = butter --) 100g = butter
60/15 = 4; 4 times as much
4 x 50g = 200g of sugar
4 x 150g = 600g of flour
4 x 100g = 400g of butter
