%/100 = is / of
7 is what percent of 30
is = 7
of = 30
% = x
now sub into the formula
x/100 = 7/30
cross multiply
(30)(x) = (7)(100)
30x = 700
x = 700/30
x = 23 1/3% or 23.33%
B because 6x4=24 and trust me pls
Since the father weighs 174 lbs on earth and 29 lbs on the moon we divide 174 by 29 to get 6 so we divide 108 by 6 to get 18lbs
Answer:
<h3>d. 1, 2, 4, 8, 16, 32</h3>
Step-by-step explanation:
Pascal's triangle is the a triangular array of binomials coefficient of equations of each degree.
<h3>n=0 1 </h3><h3>n=1 1 1</h3><h3>n=2 1 2 1</h3><h3>n=3 1 3 3 1</h3><h3>n=4 1 4 6 4 1</h3><h3>n=5 1 5 10 10 5 1</h3><h3 />
An easy way to list Pacsal's triangles is the number below Two numbers is the sum of those two numbers.
for example look at the number 10 at the triangle it is actually the sum of Two numbers above it 6 and 4
after listing pascals triangle we can calculate sum as 1,2,4,8,16,32
<u>Method 2</u>
Sum of numbers in nth row is
so sums are ,,,,,
or, 1,2,4,8,16,32
answers
question 1 = -0.5
question 2 = 6 - 3y
question 3 = 3x + 6
question 1
to evaluate (x + 1)/3 when x = -2.5, plug the value of x into the equation
(x + 1)/3
= (-2.5 + 1)/3
= (-1.5)/3
= -0.5
question 2
to solve this, distribute the 1/2 through the parentheses
(1/2) * (4 − 6y + 8)
= (1/2 * 4) + (1/2 * -6y) + (1/2 * 8)
= 2 + (-3y) + 4
= 6 - 3y
question 3
to solve this, distribute the 3 through the parentheses
3(x + 2)
= (3 * x) + (3 * 2)
= 3x + 6
<em>note - i tried to plug -2.5 into x + (1/3) for question 1, but the answer wasn't among the solutions, so i assumed the equation was (x+1)/3 instead since its answer was among the solutions</em>
