Answer: 15% I think
Step-by-step explanation:
The percent of increase in the amount of shampoo the new bottle contains is 25%.
Given that, a certain brand of shampoo contains 12 ounces in a bottle and the new type of bottle contains 15 ounces of shampoo.
What is the percentage of increase?Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage.
Percentage increase = (Final value - Initial value) / Initial value × 100
Now, initial value = 12 and final value = 15
Percentage increase = (15-12)/12 × 100
= 3/12 × 100
= 1/4 × 100
=25%
Therefore, the percent of increase in the amount of shampoo the new bottle contains is 25%.

At the beginning of the year, the number of books owned by a library was 10,000. Since then, it has grown by 1% each month.
Which expressions represent the number of books, in thousands, owned by the library 5 years later if it continues to grow at that rate?
Answer:
y = 10(1.01)^60
Step-by-step explanation:
The general equation of exponential growth is
y = ab^x
b has to do with the rate of growth.
b = 1 + r, so in this case, b = 1 + 1% = 1 + 0.01 = 1.01.
Now we have
y = a(1.01)^x
a is the initial value, so now we have
y = 10000(1.01)^x
where y is the number of books after x months
Since you need the number of books after 5 years, we must convert 5 years into months.
5 years * (12 months)/year = 60 months
The problem wants the expression in thousands of books, so we divide the initial value by 1000.
Answer: y = 10(1.01)^60
Expression representing the number of books after 5 years,
[tex]A(60)=10000(1.01)^{60}[/tex]
Exponential growth: Exponential growth function is given by,[tex]A(t)=A_0(1+r)^t[/tex]
Here, [tex]A(t)=[/tex] Final amount
[tex]A_0=[/tex] Initial amount
[tex]r=[/tex] Growth rate
[tex]t=[/tex] Duration or time
Given in the question,
Initial number of books = 10000 Growth rate = 1% Duration = 5 years ≈ 60 monthsSubstitute these values in the expression,
[tex]A(t)=A_0(1+r)^t[/tex]
[tex]A(60)=10000(1+0.01)^{60}[/tex]
Therefore, expression representing the number of books after 5 years will be → [tex]A(60)=10000(1.01)^{60}[/tex]

Answer:
ps and qr is parellel so the 70°and x is co interior angles.
so, our equation will be look like .
70°+x=180°
x=180°-70°
x=110°
The sides PS and QR are parallel for x = 110°
Option 4 is correct.
What are consecutive-interior angles?The pair of non-adjacent interior angles that are on the same side of the transversal are referred to as consecutive internal angles.The term "consecutive" describes events that take place side by side.
As per the given data:
PQRS is a quadrilateral with sides PS and QR parallel.
∠P = 70°
∠Q = x°
∠S = 112°
For sides PS and QR to be parallel:
∠Q + ∠P = 180° {Co-interior angles on the same side of the transversal}
x° + 70° = 180°
x = 110°
Hence, sides PS and QR are parallel for x = 110°

1. How much water should be added to 8 mL of 6% saline solution to reduce the concentration to 4%?
Answer:
Amount of active ingredient is 0.04(8+x)= 0.32+0.4x
---------------
EQUATION:
active ingre. + active ingre. = active ingre
0.48 + 0 = 0.32 + 0.04x
0.16 = 0.04x
x=4ML (amount of water that must be added)
The amount of water that must be added is 4 ml to 8 mL of 6% saline solution to reduce the concentration to 4%.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
8 mL of 6% saline solution to reduce the concentration to 4%.
Let x be the amount that should be added to 8 mL of 6% saline solution to reduce the concentration to 4%.
The amount of active ingredients is
0.04(8 + x) = 0.32 + 0.4x
Active ingredients + active ingredients = active ingredients
0.48 + 0 = 0.32 + 0.04x
0.16 = 0.04x
x=4 ml; the amount of water that must be added
Thus, the amount of water that must be added is 4 ml to 8 mL of 6% saline solution to reduce the concentration to 4%.

A light bulb consumes 11700 watt-hours in 3 days and 6 hours. How many watt hours does it consume per day?
Answer:
3600 watt-hours consumed per day.
Step-by-step explanation:
First we'll want to find how many hours are in 3 days and 6 hours.
3 x 24 = 72 + 6 = 78
78 hours is 3 days and 6 hours.
We then divide 11700 by 78 to find out how many watt-hours it will consume per hour.
11700 / 78 = 150
Now that we know how many watt-hours it will consume per hour, we can multiply it by 24 to find out how many it will consume in a day.
150 x 24 = 3600

Given the side measurements, classify the triangle as acute, obtuse, right, or not a triangle. 8, 12, 14
Answer: It's an acute triangle.
Step-by-step explanation: I have the same problem, and I tried each choice, acute was the correct answer
The triangle with side lengths 8, 12, 14 is an obtuse triangle.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
To determine whether the triangle is acute, obtuse, or right, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.
8² + 12² = 64 + 144 = 208
14² = 196
Since 208 is greater than 196, we can see that the triangle does not satisfy the Pythagorean theorem. Therefore, the triangle is not a right triangle.
Since the longest side is 14 and the sum of the squares of the two shorter sides is less than the square of the longest side, we can conclude that the triangle is obtuse.
Therefore, the triangle with side lengths 8, 12, 14 is an obtuse triangle.
