Answer:
08, 15, 17
Step-by-step explanation:
Use the Pythagorean theorem.
Where the sum of both legs squared is equal to the hypotenuse squared.
8² + 15² = 17²
64 + 225 = 17²
289 = 17²
289 = 289
The side lengths that represent Pythagorean triplets are 08, 15, 17.
Answer:
Step-by-step explanation:
It’s made up of the 1 dollar coin , .50 cents coin, .25 cents coin, and the .10 cents coin. If you multiply each by 25 you get the exact value , so these coins make it up but there is exactly 25 of each
Surface area of a rectangular pyramid = A + 1/2 p s
Where:
A = area of the base
p = perimeter of the base
s= salnt height = 5 in
A = Area of a rectangle = length x width = 8 x 4 = 32 in2
Perimeter of the base = 2 lenght + 2 width = 2(8)+2(4) = 24 in2
SA = 32 + 1/2 * 24 * 5 = 92 in2
Answer:
0.67 / 100 : 31^3 : 31^3 / 25cm^3
x 10
0.67 / 100 = 67 / 10000000 grams/cm : 29791 / 15625 / 29791
149253.731 : 0.52
divide by 1000
= 149.253731
= 149.3 kg
Ratio kg = 149.3 : 0.5
Step-by-step explanation:
Mole Ratio
The mole ratio compares the number of moles in a balanced equation.
This is the comparison between the coefficients in front of the chemical formulas.
If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species.
Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.
Mole Ratio Units
Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2 to 1 mole of H2 is 3:1 or 3 mol O2: 1 mol H2.
Answer:
Number of term = 48
Step-by-step explanation:
GIven:
Arithmetic progression
2,5,8..
Total sum of Arithmetic progression is 392
Find:
Number of term
Computation:
First term a = 2
Difference d = 5 - 2 = 3
Sn = [n/2][2a + (n-1)d]
392 = [n/2][2(2) + (n-1)3]
392 = [n/2][4 + 3n - 3]
784 = [n][1 + 3n]
784 = n + 3n²
3n² + n - 784
n = 48 , n = -49
Number of term = 48
