Answer:
27 inches long
Step-by-step explanation:
621 = 23l
l = 27
Square, rectangle, quadtratle
.011 = 1.1* 10^-2 in scientific notation
1.1*10^-2 * 7.5 * 10^18 = (1.1*7.5) * 10 ^ (-2+18)
8.25*10^16
The sand weighs 8.25 * 16^16 grams.
Answer:
(–3, –4)
Step-by-step explanation:
Given pair of linear equation
-4x+y = 8
=> y = 8 + 4x _____(1)
x - 5y = 17 (2)
substituting value of y from equation 1 in equation 2 we have
x - 5(8 + 4x) = 17
=> x - 5*8 -5*4x = 17
=> x - 40 - 20x = 17
=> -40 - 19x = 17
=> -19x = 17+40 = 57
=> x = 57/-19 = -3
Thus, x = -3
y = 8 + 4x = 8 +4(-3) = 8 -12 = -4
Thus, y = -4
Hence, paired solution for given equation is (–3, –4).
You can solve this problem by writing an equation of ratios and finding the value of the unknown that way:
10 ft 17 ft
---------- * ---------
50 ft x
Then 10x = 850, and so x = 85 feet.
