Yes, 3.3 is a rational number.
(2x - 3)² = 4x² - 12x + 9
k = 4
k = 395/553
k = 5/7
280m * 5/7 = 200m
350m * 5/7 = 250m
395m + 200m + 250m = 845m
10x + 7° + 4x = 35°
14x + 7° = 35° |-7°
14x = 28° | : 14
x = 2°
4 : 1/4 = 4*4 = 16
Yes 3.3 is a rational number!!
The answer was wrong also there are wo questions.
sin A = 5/8.
k = 16.
The linear inequality is 3x - y + 2 < 0.
N + D + Q = 140................................(1) 0.05N + 0.10D + 0.25Q =19..............(2) Q - D = 10..........................................(3) Solve for N, D, Q by using substitutions:
N = 50 Nickels D = 40 Dimes Q = 50 Quarters.
Yes, the number 3.3 is a rational number because it doesn't keep going on forever and ever.
Hope my answer helps!
At Barlow School: 4 / 9 * 873 = 388 boys.
At Willow School: 2 / 3 * 630 = 420 girls. At Willow School: 630 - 420 girls =210 boys.
Barlow School has =388 boys Willow School has =210 boys. So: 388 - 210 = 178 more boys at Barlow School than Willow School.
A) 6/12 = 1/2
B) 10/12 = 5/6
C) 9/12 = 3/4
D) 8/12 = 2/3
-6(x - 3) + 2x = -4x + 18
-6x +18 + 2x = -4x +18
-4x +18 = -4x + 18 |+4x - 18
0 = 0
Let the number Liters of 5% solution needed =F
Then, the number of Liters of 40% solution needed =10 - F
0.05F + 0.4*[10 - F] =0.20 * 10, solve for F
F = 40 / 7 = 5 + 5/7 Liters of 5% solution.
10 - 5 5/7 = 4 + 2/7 Liters of 40% solution.
The largest number that I can think of is: 643,210
You have not made your meaning clear at all.
Your last two comments have both been totally without meaning.
Do you think the answer given is incorrect?
Why do you think this? Give your reason.
Do you know what the correct answer is said to be? Do you know why?
But it says seperated by commas so there is more than one, right??
As follows:
That s wrong
Pls show work
a and b are the same as their GCD and LCM. In other words:
GCD(210, 210^3) = 210, and
LCM(210, 210^3) = 210^3. If "a" stands for 210, then "a" can only take one value of 210. If you double it, say to 420, then the new GCD = 420....and so on.
The possible values of cos A are 1 and -1/2.
