Answer: 2001 people attended the football game this week.
Step-by-step explanation:
Given: Total people came to the ball game = 2300
Decrease percent = 13%
Number of people attended the football game this week = p-0.13p, where p= number of people attended football last week.
for p= 2300
Number of people attended the football game this week = 2300- 0.13 x (2300)
=2300- 299
= 2001
hence, 2001 people attended the football game this week.

Decide whether this statement is always true, never true, or sometimes true, and explain why: In a quadratic equation of the form 0 = ax2 + bx + c, there will be two real solutions if a and c are of opposite signs
Answer:
Always true
Step-by-step explanation:
Here, we want to evaluate if the given statement is true
The discriminant D can be calculated using the formula;
b^2 - 4ac
if D is greater than 0, then we will have only real roots
In a case where a and c are of opposite signs;
then -4ac will always give a positive value which can be added to b^2
This positive value will ensure that D is greater than zero and hence we can have only real roots
So this assertion is always true if a and c are of opposite signs

The angle measurements in the diagram are represented
by the following expressions.
ZA= 63 - 189
ZB = 142 + 38°
Solve for x and then find the measure of ZA:
Answer:
∠A = 30°Step-by-step explanation:
∠A + ∠B = 180
where ∠A = 6x - 18
∠B = 14x + 38
first step is to solve for x:
6x - 18 + 14x + 38 = 180
6x + 14x = 180 + 18 - 38
20x = 160
x = 160 / 20
x = 8
now substitute x=8 into angle A
∠A = 6x - 18
∠A = 6(8) - 18
∠A = 30°
if you use synthetic division for this polynomial: 3x^5-12x^4+12x^3+30x^2-39x-42. What would the answer be?
Answer : x^5 - 4x^4 +4x^3 + 10x^2 - 13x - 14
Explanation :
(3x^5-12x^4+12x^3+30x^2-39x-42)/3 = x^5 - 4x^4 +4x^3 + 10x^2 - 13x - 14
i want to purchase a necklace for 325$ . ive already saved 115.00 and can set aside 22.00$ a week . which inequality can be used to find the number of weeks it will take to save at least 325.00$?
Answer:
22w + 115 = 325 w = about 10 weeks
Step-by-step explanation:
The first part of this inequaltiy is 22w. Since he/she will set aside $22 a week, you would put a variable because the number of weeks you will need to set aside $22 is unknown therefore you put a variable that makes sense. I put w because you can say that w=weeks. The next part of the inequality is adding $115 because he/she has already saved $115 so we add that to 22w. Finally 22w+115 has to equal $325 because that is how much the necklace costs. Hope this helps!

There are 28 red pens and 84 black pens in a bag.
Write down the ratio of the number of red pens to the number of black pens.
Give your ratio in its simplest form.
Answer:
1/3
Step-by-step explanation:
The ratio can be written as a fraction. This would be 28/84. You simplify ratios just like how you simplify a fraction. 28x3 is actually 84, so the answer in simplest form is 1/3.
Hope this helps and have a great day!! []~(^▽^)~*
The ratio of the number of red pens to the number of black pens in simplest form is, 1 : 3.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
There are 28 red pens and 84 black pens in a bag.
Here, Number of red pens = 28
And, Number of black pens = 84
Hence, The ratio of the number of red pens to the number of black pens is,
⇒ Number of red pens : Number of black pens
⇒ 28 : 84
⇒ 28/84
⇒ 14 / 42
⇒ 1 / 3
⇒ 1 : 3

A chemical company makes up batches of copper sulfate solution by adding 250 kg of copper sulfate powder to 1000 liters of water. A laboratory chemist wants to make a solution of identical concentration, but only needs 350 mL (0.35 liters) of solution.
How much copper sulfate powder should the chemist add to the water? Enter your answer in the box below in decimal format.
The mass of copper sulfate that the chemist should add is______
kg.
help me please
Answer:
0.07 kgStep-by-step explanation:
Assuming copper sulfate has same density as waterChemical to water ratio as per given is:
250 kg : 1000 liter = 1 kg : 4 literLab solution is 350 ml
Converting to same ratio as above:
350/(1 + 4) = 70 ml
70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 mlAnswer is 0.07 kg

Which of the equations below can be solved by square roots? How would you solve the other equation? Explain your reasoning. Give the solutions to both equations. Equation A: x? - 9x = 0 Equation B : x2-9=0
Answer:
Equation A is factoring, x=9 and x=0
Equation B is the square root, x=3
The equation A: x² - 9 = 0 can be solved by square root method
The equation B: x² - 9x = 0 can only be solved by factoring
The given equations are:
Equation A: x² - 9x = 0
Equation B: x² - 9 = 0
The equation x² - 9 can be rewritten as:
x² - 3² = 0
This is a difference of two squares which can be further expressed as:
(x - 3)(x + 3) = 0
x - 3 = 0
x = 3
x + 3 = 0
x = -3
This shows that the equation x² - 9 = 0 has two roots x = -3 and x = 3
Also, from x² - 9 = 0
[tex]x = \pm\sqrt{9} \\\\x = \pm3[/tex]
For the equation x² - 9x = 0
This can be factored as x(x - 9) = 0
x = 0, x = 9
This is not solved by the square root method.
Therefore, the equation x² - 9 = 0 can be solved by square root method

The complex number with modifying bar will be 12 - i so option (A) will be correct.
What is a complex number?Complex numbers are helpful in finding the square root of negative numbers.
A complex number is the sum of a real number and an imaginary number.
The general form of a complex number is a + ib where the first part a called real and the ib is called imaginary.
If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).
Bar of complex number = replace i (iota) with - i (iota)
since z = 12 + i
So,
z bar = 12 - i

Given
- 2(- 3x + 3) + 2x = 58 ← distribute and simplify left side
6x - 6 + 2x = 58
8x - 6 = 58 ( add 6 to both sides )
8x = 64 ( divide both sides by 8 )

Because Five-thirds less-than three-halves, the slope of the climbing equipment at the playground is greater.
Because Three-fifths greater-than two-thirds, the slope of the climbing equipment at the gym is greater.
Because Three-fifths less-than two-thirds, the slope of the climbing equipment at the playground is greater.
Answer:
I think its D but I'm not that sure about it.
Step-by-step explanation:
Because three fifths less than two thirds, the slope of te climbing equipment at the playground is greater.
Answer:
A)
Step-by-step explanation:
A piece of climbing equipment at a playground is 6 feet high and extends 4 feet horizontally.
Therefore its slope = length of the equipment vertically / length of equipment horizontally
= 6/4 = 3/2 = 1.5
And, A piece of climbing equipment at a gym is 10 feet high and extends 6 feet horizontally.
Therefore slope, = 10/6 = 5/3=1.67 (approx)

If f(1)=7f(1)=7 and f(n)=f(n-1)+2f(n)=f(n−1)+2 then find the value of f(4)f(4).
Answer:
Step-by-step explanation: f1 =7
f2 = 5(7) + 2 = 37
f3 = 5(37) + 2 = 27
f4 = 5(9) + 2 = 47____
The value of f(4)f(4) f(1) = 7f(1) = 7 and f(n) = f(n-1) + 2f(n) = f(n−1) + 2 is,
121.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, f(1) = 7f(1) = 7 and f(n) = f(n-1) + 2f(n) = f(n−1) + 2.
By this pattern,
f(4)f(4) = [f(4 - 1) + 2f(4)][f(4 - 1) + 2f(4)].
f(4)f(4) = [f(3) + 2f(4)][f(3) + 2f(4)].
f(4)f(4) = [f(3) + 2(4)][f(3) + 2(4)].
f(4)f(4) = [3 + 8][3 + 8].
f(4)f(4) = [11][11].
f(4)f(4) = 121.
