77.1% chance that all 3 orders are correct.
For three independent events to find the probability of each one occurring we multiply the probabilities together. .917*.917*.917 = .77109 or 77.1 percent chance of all three outcomes being favorable.
<u><em>Answer: x=-25 and -25=x *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
multiply by -5 both sides of an equation.
(-2/5x)(-5)=10(-5)
simplify by equation.
2x=-50
divide by 2 both sides of an equation.
2x/2=-50/2
simplify by equation.
50/2=25
25*2=50
50/25=2
It changes positive to negative.
x=-25 and -25=x
Hope this helps!
Thanks!
Have a great day!
Answer:
63 in
Step-by-step explanation:
Distance around the tire is actually the circumference.
Circumference of circle=2πr
Where r=diameter/2=20/2=10 in.
C=2(3.14)(10)
C=62.8 in
C=63 in
Answer:
Austin paid 9 bucks more
Step-by-step explanation:
Zach : original cost is 60 bucks.....on sale for 35% off....means he paid (100% - 35%) = 65%.
65% of 60 = 0.65(60) = 39 <=== what Zach paid
Austin : original price 60 bucks...on sale for 20% off...so he paid 80%
80% of 60 = 0.8(60) = $ 48 <=== what Austin paid
Austin paid (48 - 39) = $ 9 more then Zach
There are 8 pints in a gallon so 5 times 8 equals 40
