To start off with, the probability to draw the short straw is 1/9 and each time someone picks the long straw the denominator (the 9) decreases by one which means that the odds of someone picking it get higher.
To solve this problem you need to use the cross product method!
3 miles → 25.8 minutes
1 mile → × minutes
→ (25.8 • 1) ÷ 3 = × minutes
→ 25.8 ÷ 3 = × minutes
→ 8.6 = × minutes
So your answer is that it takes beth 8.6 minutes to run 1 mile!
There you go! I really hope this helped, if there’s anything just let me know! ☻
Answer:
Step-by-step explanation
Step 1: multiply the coefficient a and the constant c. Given that the general expression of a parabolic equation is ax^2+bx+c
3*5=15
Step 2: examine the coefficient b and try to find 2 numbers which you can multiply to get 15, add or subtract and get - 8
In this Case: - 3*-5=15 and - 3+(-5)= - 8
Step3:
You separate the equation in terms of the two factors you have found
3x^2-3x-5x+5=0
Step 4:Factorise
3x(x-1)-5(x-1)=0
(3x-5)(x-1)=0
Answer:
35.98
Step-by-step explanation:
To find the perimeter take 1/2 of the circumference plus the length of the diameter
P = 1/2 * pi *d + d
=1/2 pi 14 +14
= 7pi +14
Letting pi = 3.14
7(3.14) + 14
21.98 +14
35.98
Answer:
try dividing the dividend and then multiplying it by the center number
