Answers
Answer:
[tex]\huge\boxed{25\%}[/tex]
Step-by-step explanation:
Previous Price = 2000
Current = 2500
Increase:
=> 2500 - 2000
=> 500
%age change:
=> [tex]\frac{500}{2000} * 100 \%[/tex]
=> ( 5 * 5 ) %
=> 25%
Answer:
Percentage change = 25%Step-by-step explanation:
To find the percentage change we use the formula
[tex]Percentage \: \: change \: \: = \frac{change}{original \: \: quantity} \times 100[/tex]To find the change subtract the lesser one from the larger one
Original price = 2000
Final price = 2500
Change = 2500 - 2000 = 500
So the percentage change is

Percentage change = 25%Hope this helps you
HELP PLEASE The value of a stock can be modeled by this equation. V = 23n + 42; where V is the value, in dollars, and n represents the number of months since purchase. Which statements correctly interpret the slope of the line? A. The slope of the line is 42. This means that the value of the stock increases $42 for each additional month since purchase. B. The slope of the line is 42. This means that the initial value of the stock was $42. C. The slope of the line is 23. This means that the initial value of the stock was $23. D. The slope of the line is 23. This means that the value of the stock increases $23 for each additional month since purchase.
Answers
Answer:
D. The slope of the line is 23. This means that the value of the stock increases $23 for each additional month since purchase.
Step-by-step explanation:
In the basic equation y = mx + b, m is the slope. In this situation, 23 is the slope because it is the coefficient.
42 is not the slope because it is the y-intercept.
D is the correct answer because the slope is 23, which means in this situation that the stock's value increases by $23 for each additional month after the purchase.
Answer:
D.
Step-by-step explanation:
The slope is the coefficient of n ( the month) which is 23.
This means the stock increases each month by a factor of 23.
Omar uses the factor theorem to determine whether x−3 is a factor of 4x4−12x2−18x−162. How does he proceed to the correct answer? A-Omar evaluates 4x4−12x2−18x−162 when x = 3. He determines that the value of the expression is 108 and concludes that x−3 is a factor. B-Omar evaluates 4x4−12x2−18x−162 when x=−3. He determines that the value of the expression is 108 and concludes that x−3 is not a factor. C-Omar evaluates 4x4−12x2−18x−162 when x = 3. He determines that the value of the expression is 0 and concludes that x−3 is a factor. D-Omar evaluates 4x4−12x2−18x−162 when x=−3. He determines that the value of the expression is 0 and concludes that x−3 is a factor.
Answers
Answer:
C- Omar evaluates 4x⁴−12x²−18x−162 when x = 3. He determines that the value of the expression is 0 and concludes that x−3 is a factor.
Step-by-step explanation:
Factor Theorem can be defined as a method or theorem that is used in mathematics to simplify polynomials. It is used to confirm if a particular root is the real root of the polynomial.
Factor Theorem states that:
a) If p(x) is a polynomial of degree of n is greater than 1 (n > 1) and a is any real number, then
b) x – a is a factor of p(x)
if p(a) = 0, x – a is a factor of p(x).
In the question above, we are told that:
Omar uses the factor theorem to determine whether x−3 is a factor of 4x⁴ −12x² − 18x − 162.
Using Factor Theorem,
b) x – a is a factor of p(x)
if p(a) = 0, x – a is a factor of p(x).
x - 3 = 0, x = 3
p(x) = 4x⁴ −12x² − 18x − 162 = 0
p(3) = 4(3)⁴ - 12(3)² - 18(3) - 162 = 0
p(3) = 4(81) - 12(9) - 18(3) - 162 = 0
p(3) = 324 - 108 - 54 - 162 = 0
p(3) = 324 - 324 = 0
p(3) = 0 = 0
Hence, since p(3) = 0, x - 3 is a factor of polynomial 4x⁴ −12x² − 18x − 162 .
Therefore,Option C- "Omar evaluates 4x⁴−12x²−18x−162 when x = 3. He determines that the value of the expression is 0 and concludes that x−3 is a factor. " is the correct answer.

Answers
Answer:
7 of 100 parts have been shaded, and 7 hundredths is written as 0.07
Step-by-step explanation:
Note that we have a grid of 100 squares and 7 of those squares are shaded. We can represent the shaded portion by saying 7/100 which is equivalent to .07.
With this information, we can say 7 out of 100 is shaded and is representative of 7 hundredths.
Note that each digit after the decimal is a multiple of (1/10). We can express this as (1/10)^n where n is the digit place after the decimal.
In this case, we have 7, two digits after the decimal so it will be equivalent to 7 * (1/10)^2 = 7 * (1/100) = 7/100.

Answer:
1) 30%, 50%, 10%
2) x = 24
Step-by-step explanation:
Hey there!
1) "MATHMATICS"
a) Vowels - a, e, i, o, u
This is 3/10 of the letters meaning pulling a vowel is 30%.
b) Constants - B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, X, Z
Well there are 5 constants in mathematics so the percent is 50%.
c) Letter "m"
The letter m is 1/10 meaning pulling the letter m is a 10%.
2) 8 added to twice a number gives 40. Find the number
Well lets set u an equation,
8 + x + 8 = 40
16 + x = 40
-16
x = 24
Hope this helps :)
Answer:
In bold.
Step-by-step explanation:
1.
There are a total of 11 letters in the bag including 4 vowels, 7 consonants.
The letter m appears twice in mathematics.
(a) Probability(getting a vowel) = 4/11.
(b) Probability(getting a consonant) = 7/11.
(c) Probability(getting a letter m) = 2/11.

Let the number be n, then:
8 + 2n = 40

Answers
Answer:
[tex]\approx \bold{44\ or\ 45}[/tex]
Step-by-step explanation:

Diameter of spherical metal ball = 400 mm = 40 cm
Radius of spherical metal ball = 20 cm
Volume of a sphere is given as:

Step-by-step explanation:
Hydrogen and oxygen are elements that form the compound known as water.
Water comes pouring out, it drips, it dribbles, and it comes from a spout.
Answer:
Water
Step-by-step explanation:
Most of the water in our world is a combination of "ordinary" hydrogen atoms with "ordinary" oxygen atoms, but there are actually three different istopes (atomic varieties) of hydrogen and each of those can combine with oxygen to give a different kind of water.
If deuterium (hydrogen whose atoms contain one neutron and one proton instead of just one proton by itself) combines with oxygen, we get something called heavy water, which is about 10% heavier than normal water.
Similarly, tritium (hydrogen with two neutrons and one proton) can combine with oxygen to make something called super heavy water.
Water comes pouring out it drips and it dribbles and it comes from a spout.

The length of a rectangle is 6 meters less than twice its width. If the area of the rectangle is 308 m2, what are its dimensions?
Answers
Answer:
length = 22cmwidth = 14cmStep-by-step explanation:
Area of a rectangle = l × w
where
l is the length
w is the width
From the question
Area = 308 m²
The length of a rectangle is 6 meters less than twice its width is written as
l = 2w - 6
Substitute this into the above formula and solve for the width
We have
308 = (2w - 6)w
2w² - 6w = 308
2w² - 6w - 308 = 0
Divide both sides by 2
We have
w² - 3w - 154 = 0
( w + 11)( w - 14) = 0
w + 11 = 0 w - 14 = 0
w = - 11 w = 14
Since the width cannot be negative
w = 14
Substitute w = 14 into l = 2w - 6
That's
l = 14(2) - 6
l = 28 - 6
l = 22
Therefore
length = 22cm
width = 14cm

for each diagram, determine whether angles 1 & 2 form a linear pair, heeelp please :(
Answers
Answer:
only (12) has a linear pair
Step-by-step explanation:
Recall that for two angles to be called a "Linear Pair", they need to satisfy several conditions:
1) The two lines must intersect at a shared point (i.e common vertex)
2) The two angles must be adjacent (i.e immediately next to one another)
3) The two angles must add up to 180 degrees.
In our case,
in (9), the angles are not adjacent and they do not add up to 180 deg, so this is NOT a linear pair
in (10), the angles are not adjacent and they do not add up to 180 deg, so this is NOT a linear pair
in (11), the lines do not intersect at a shared point(they do not have a common vertex). Plus we cannot be 100% sure that they add up to 180 deg. Hence this is not a linear pari
in (12), we can see that the angles satisfy all 3 conditions above. This is a linear pair.

Answers
Answer:
a) 63.8 in³
Step-by-step explanation:
so the cylinder is 12 inches high
πr²h = π(1.25)²(12) = 58.90 in³
cone is 3 inches high
1/3πr²h = = 1/3π(1.25)²(3) = 4.91 in³
58.90 + 4.91 = 63.81 in³
Answer:
63.8 in
Step-by-step explanation:
the formula of te volume of the cone is : πr²h/3
the height of te cone is the height of the tip
V=π(1.25)² * 3/3
V1=4.91( rounded to the nearest hundredth)
volume of the cylinder =πr²h ( the height of cylinder=25-3=23)
V2=π(1.25)²*12
V2=58.90
V1+V2=4.91 +58.90=63.81 ≅63.8
