(H) The price is 75% of what it was before.
Step-by-step explanation:
Let's go through all the answer choices:
(A) The price doubled.
(B) The price is 150% of the price before.
(E) The price is now 1.5 times greater than what it was before.
(F) The price now is 662 % of what it was before.
(G) The price now is 200% of what it was before.
knowing that decreased meaning smaller or fewer.
Thus, it can't be doubled or more than 100% as well was greater.
Hence, the best answer is
(C) The price was reduced by a quarter
(H) The price is 75% of what it was before.
Note:
Reduced = Smaller, Less amount
Greater = More
Doubled = More
Decreased = Smaller, Less amount.

Solve the system of linear equations in two variables by elimination or substitution.
4x+ 3y=2
2x-3y=1
Answers
Answer:
( [tex]\frac{1}{2}[/tex], 0 )
Step-by-step explanation:
Given the 2 equations
4x + 3y = 2 → (1)
2x - 3y = 1 → (2)
Adding (1) and (2) term by term will eliminate the y- term, that is
6x = 3 ( divide both sides by 6 )
x = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Substitute x = [tex]\frac{1}{2}[/tex] into either of the 2 equations and evaluate for y
Substituting into (1)
4([tex]\frac{1}{2}[/tex] ) + 3y = 2
2 + 3y = 2 ( subtract 2 from both sides )
3y = 0 ⇒ y = 0
Solution is ( [tex]\frac{1}{2}[/tex], 0 )

There are tables (4) and (5) represent quadratic relationships.
What is the quadratic relationship?A quadratic relationship is equivalent to a quadratic formula. These relations are frequently used to determine the height of falling objects, kicked balls, or an arched bridge.
As per table (4), we have
x y
0 4
1 -4
2 -4
3 4
Substitute these points in the graph, we get it represents quadratic relationships.
When plotting the graph of a quadratic relation, always display the significant points, the vertex, and the crossings with the axes.
As per table (5), we have
x y
0 -4
1 -8
2 -10
3 -10
When we substitute these points in the graph, we see that it also shows quadratic relations.
Thus, tables (4) and (5) represent quadratic relationships.

of the first week you notice
5 squirrels. At the end of
the second week you see 8
and by the end of the third
week there are 11. If they
continue to move to your
yard at the same rate how
many squirrels will there be
after 28 week
Answers
Answer:
140 squirrels
Step-by-step explanation:
first week, there are 5 squirrels.
second week, there are 8 squirrels.
third week, there are 11 squirrels.
let's calculate the amount of squirrels at the end of 28 weeks. from the statement given, an addition of 3 squirrels for every week.
by cross multiply method:
5 squirrels = 1 week
x squirrels = 28 weeks
x = 28 x 5
x = 140 squirrels.
so you will have an amount of 140 squirrels after 28 weeks.
If f(x) = 2x – 10, what is f(4)

Step-by-step explanation:
F(x)=2x-10
Ok, so when you need to know f(4) you plug in 4 for x
f(4)=2(4)-10
2x4 = 8
8-10= -2
f(4)= -2
Hope this helps!
Hi! Hope you're enjoying your day!
In order to solve this, all we have to do is plug in the value of x.
So we're given that
f(x)=2x-10
So f of x is equal to 2 times x minus 10.
Thus
f of 4 is equal to 2 times 4 minus 10 (it can be simplified, right?) :)
f(4)=8-10
f(4)=-2
Hence, the answer is

x = -1/6
Step-by-step explanation:
Firstly, you need to expand the brackets. So this would give, 8 + 12x - 6.
Then you collect like terms to give, 12x + 2. After this, we solve for x. To do this we need to assume that all this is = 0. Then it's easy to solve:
12x + 2 = 0
12x = -2
x = -2/12
x = -1/6

we can see that the triangle is isosceles since it has 2 equal sides
so that means 2 equal angles then :
x + 17 = 4x - 34
3x = 51
x = 17

the sum of 3 triangles angles = 180
6x + 10 + x + 17 + 4x - 34 = 180

The volume of this right prism is 214.5 ft. What is the height, x, of the prism? 5 ft Enter your answer as a decimal in the box. 5 ft 5.8 ft X= ft x A 8 ft. Pls help me!
Answers
The volume of the right prism is the product of the length, width and height
The height of the prism is 7.40 ft
How to determine the height of the prism?The given parameters are:
Volume = 214.5 ft cube
Length = 5 ft
Width = 5.8 ft
The volume of the right prism is calculated as:
Volume = Length * Width * Height
So, we have:
214.5 = 5 * 5.8 * Height
Evaluate the product
214.5 = 29 * Height
Divide both sides by 29
7.40 = Height
Rewrite as:
Height = 7.40
Hence, the height of the prism is 7.40 ft

AC = 150 Feet
CB = 75 feet.
BD = 100 feet
You use the tangent here.
Tan(A) = opposite/ Adjacent
Opposite = BD = 100 feet
Adjacent = AB = AC + CB = 150 + 75 = 225 feet.
Tan(A) = 100 / 225
Tan(A) = 0.4444

The rectangle is 12.0 feet wide and 7.0 feet long. how much string should the artist use? round your answer to the nearest tenth of a foot
feet of string:
Answers
Answer:
65.8 ft
Step-by-step explanation:
The number of strings required to tie each vertex to the other three will be ...
(4)(3)/2 = 6
Those strings will be perimeter strings plus two diagonal strings. The lengths of the perimeter strings are given as 12 ft and 7 ft. The lengths of the diagonal strings can be found using the Pythagorean theorem.
d² = 12² +7² = 144 +49 = 193
d = √193 ≈ 13.892
Then the total length of all strings is ...
L = 2(12.0 +7.0 +13.9) = 65.8 . . . . feet
The artist will need 65.8 feet of string.

Answers
The cost of a utility for a pole with a diameter of 41 cm and a height of 780 cm is $3894697.41
Density formula
The density formula is given by:
Density = mass/volume
The volume of the cylinder = π * radius² * height
Radius = diameter / 2 = 41/2 = 20.5, height = 780 cm. Hence:
Volume = π * 20.5² * 780 = 1029798 cm³
Density = mass/volume
6.1 = mass/1029798
mass = 6281770 kg
Cost = 6281770 kg * $0.62 per kilogram = $3894697.41

Mrs. Jenkins has petri dishes to divide evenly among the students. She wants to make sure she has enough petri dishes. The number of dishes each student gets depends on the number of students. The more students that decide to do the bacteria experiment, the fewer the number of petri dishes each student gets.
Answers
Answer:
Ok, suppose that there are M Petri dishes, where M is an integer number.
If there are N students in the class, then the number of Petri dishes that each student gets is:
# = M/N.
(always that N divides M)
If not, we will have a remainder, R, of Petri dishes such that:
M ≥ N
R < N
This means that:
The total number of Petri dishes must be equal or larger than the number of students.
If M is larger than N, and N does not divide M, then the remainder of the quotient will be smaller than N.
Now with this, you can replace the numbers and do the math.
"The more students that decide to do the bacteria experiment, the fewer the number of Petri dishes each student gets."
You can easily see this because the equation for the number of Petri dishes that each student gets is:
# = M/N.
Here, N is in the denominator, then if the number of students in the class increases, the denominator in the operation increases, which means that the quotient will be smaller.
