Answer:
10:13
Step-by-step explanation:
you take the information and list it in order so first 10 white then 6 pink and last 7 blue and now then you take the white socks witch is 10 then you take the pink and blue add them witch is 13 and you got your answer 10:13
Answer: Greatest common factor (GCF) of 3 and 11 is 1.
Step-by-step explanation:
Answer:
b*b*b*b*b*b
Step-by-step explanation:
(b^2)^3=b^6 since exponents raised to the exponent is just multiplying the two.
b^6 since you cant have exponents is b*b*b*b*b*b or b multiplied by itslef 6 times
Answer:
30 minutes
Step-by-step explanation:
Nathaniel can weld 1 rail in 75 minutes, so he welds 1R = 75 min, and Brenda can weld 1 rail in 50 minutes (25 minutes faster than Nathaniel), so she welds
1R = 50 min
We want to see how many minutes it takes them both, so we need to solve both problems for the minute unit
Nathaniel: (1/75)R = 1 min (he can do one seventy-fifth of a rail per minute)
Brenda: (1/50)R = 1 min (she can do one fiftieth of a rail per minute)
notice, the equation is 1/(minutes it takes them), and we want to see how long it takes both of them, so we get the equation:
1/75 + 1/50 = 1/x
Simplify the left side with common denominator of 57(50) = 3750
We get
125/3750 = 1/x
We can cross multiply to get rid of the fractions...
125x = 3750
Divide both sides by 125 to solve for x...
x = 30, so it would take them 30 minutes to weld a rail if they work together.
If you want to find the surface area of something and it doesn't have a formula, just look at the area of each side individually and add them up!
The area of a triangle is equal to bh/2 = 16*6/2 = 48 in²
The area of the other triangle would be the same = 48 in²
The lateral side that's 10 by 9 inches = 10 * 9 = 90 in²
The other lateral side that's 10 by 9 is also = 90 in²
The lateral side that's 16 by 9 inches = 16 * 9 = 144 in²
144 + 90 + 90 + 48 + 48 = 420 in²
