Answer:
a^2 + 2ab + b^2
Step-by-step explanation:
a bag contains 300 balls. 96 balls are yellow. Which answer shows both the correct proportion and the correct percent of yellow balls in the bag.
The proportion of yellow balls in the bag is 8/25 and percentage is 32 %
What is Percentage and Proportion?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
The number of balls in the bag = 300
The number of yellow balls in the bag = 96
The proportion of yellow balls =
The number of yellow balls in the bag / The number of balls in the bag
The proportion of yellow balls = 96 / 300
= 24 / 75
= 8 / 25
Therefore , The proportion of yellow balls in the bag is 8 / 25
Now ,
The percentage of yellow balls in the bag =
Number of yellow balls in the bag / Number of balls in the bag x 100 %
The percentage of yellow balls in the bag = ( 8 / 25 ) x 100 %
= 8 x 4 %
= 32 %
Hence ,
The proportion of yellow balls in the bag is 8/25 and percentage is 32 %

pls answer this for meeee
Answer:
7 hamsters at 5 pesos each and 13 hamsters at 8 pesos each
Step-by-step explanation:
5x + 8y = 139
x + y = 20
x = 20 - y
5x + 8y = 139
5(20 - y) + 8y = 139
100 - 5y + 8y = 139
100 + 3y = 139
3y = 139 - 100
3y = 39
3y/3 = 39/3
y = 13
x + y = 20
x + 13 = 20
x = 20 - 13
x = 7

Factorise -x^2-20x-100
Answer:
(x+10)(x+10) or (x+10)^2
Step-by-step explanation:
Divide by -1 first
a=1
b=20
c=100
Since a*c whose sum is b...
1*100=100
10*10=100 and adds to 20
The answer is (x+10)(x+10) or (x+10)^2
Find the equation of the line, whose slope is 5 and x- intercept is 2
Answer:
Step-by-step explanation:
when x intercept is points given, then y = 0
So far, you have y = 5x + b where b = the yintercept
x = 2
y = 0
0 = 5x + b
0 =5 * 2 + b
0 = 10 + b Subtract 10 from both sides.
-10 = b
Equation: y = 5x - 10

help pls need help show your solution and then graph
Answer:
Step-by-step explanation:
We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.
ax^2 + bx + c
so
a=4
b=-9
c=2
you can try it by hand or use this:
https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php
you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis

What is the length of the missing side, to the nearest tenth of a centimeter?
Answer:
18.4 cm
Step-by-step explanation:
For this problem, you would use Pythagorean Theorem or a^2+b^2=c^2. Don't forget that the c in the formula is always your hypotenuse or the longest side of the triangle. The a and the b are always the legs of the triangle. (It doesn't matter which leg is which letter) The hypotenuse is also always across from the 90 degree angle. Picture the 90 degree angle as an arrow pointing to the hypotenuse. In this case, the hypotenuse (or c) is 20.7 cm. Now all you have to do is plug and chug! I hope this helps you and thanks for asking your question!!

1. First, let's simplify the equation.
[tex]y = 3(x) + 3(3) + 4[/tex] [tex]y = 3x + 9 + 4[/tex] [tex]y = 3x + 13[/tex]2. Since the equation is y = 3x + 13:
The y-intercept is 13.For every 1 unit we go to the right, we go 3 units up.Now, here's the graph!
