Answer:
False
Step-by-step explanation:
numbers are integers, the integers are negative, zero and positive,
while natural numbers are only positive,
therefore the statement is false
. False. Integers comprise negative and positive numbers (...- 3, -2, -1, 0, 1, 2, 3 ...) and natural numbers only comprise positive integers (0, 1, 2, 3 ...)

The price of a bicycle was decreased by 40% to £96. What was the price before the decrease?
Answer:
£160
Step-by-step explanation:
£160 times 0.6 equals £96
since £96 is 60% of the original price since 40% was taken off
The price of the bicycle before decrease is obtained as £160.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100. And to convert a fraction or a decimal into percentage, they are multiplied by 100.
The new price of the bicycle is £96.
And, the percent of decrease is 40%.
Suppose the original price be x.
Then, the following equation can be written for the given case as,
x - 40% × x = 96
⇒ x - 40/100x = 96
⇒ 60/100x = 96
⇒ x = 160
Hence, the original price of the bicycle is given as £160.

Solve the following formula for the specified variable.
B =1/2m(r + k) for r
Answer:
(2B/m) - k = r
Step-by-step explanation:
B =1/2m(r + k)
Multiply each side by 2
2B =m(r + k)
Divide each side by m
2B/m = m/m (r+k)
2B/m =(r+k)
Subtract k from each side
(2B/m) - k = r+k-k
(2B/m) - k = r

A school must select one student from the honors program to send to the annual math convention. Which of the following is NOT a mathematically fair way to select the student?
A) Use a random number generator to choose a student ID number.
B) Have the students play a game that involves flipping a coin. Heads is worth 2 points and tails is worth 1 point. The first student to reach 40 points wins the trip.
C) Have each teacher select their favorite student and then randomly draw one of those names.
D) Line the students up alphabetically. Each student selects a playing card. A card is then drawn from another deck. The student with the matching card wins.
Answer:
Answer is option C.
Step-by-step explanation:
This is because it does not take into account "random selection" (probability). Thus the mode of selection is biased. The mere fact that a teacher selects his favourite student means the experiment is biased.
type a is 5 feet tall and grows at a rate of 18 inches per year Type B is 10 feet tall and grows at a rate of 8 inches per year. How many years will it take for these trees to be the same height
Answer:
The height will be same in 6 years time
Step-by-step explanation:
Since we do not know the years it would take, we can call this x
Kindly note that 12 inches is 1 feet, so 5 ft would be 60 inches and 10 feet will be 120 inches
Now, the height of tree A after x years would be;
60 + 18x
For tree B, height would be 120 + 8x
Now, we were made to know that they have equal height at the xth year.
Thus;
60 + 18x = 120 + 8x
10x = 120-60
10x = 60
x = 60/10 = 6
does the equation y=4.2x represent a proportional relationship
Answer:
A proportional relationship is one in which two quantities vary directly with each other.We say the variable varies directly .If y=k.x then as x increases y also increases.Here k is called the constant of proportionality.
The given equation y = 4.2x is of the form y=k.x where k= 4.2 as x increases y value will also increase. The relation is called a proportional relationship.

the exponential function g, represented in the table, can be written as g(x)=a•b^x.
complete the equation for g(x).
please and thank you
Answer:
g(x) = [tex]12.(\frac{3}{4})^x[/tex]
Step-by-step explanation:
Exponential function g has been represented by the table attached,
Equation of the exponential function is,
g(x) = [tex]a.(b)^x[/tex]
Now we substitute the values of x and g(x) from the table,
For a point (0, 12),
12 = [tex]a(b)^0[/tex]
a = 12
For another point (1, 9),
9 = [tex]a.(b)^1[/tex]
9 = a × b
9 = 12 × b
b = [tex]\frac{9}{12}[/tex]
b = [tex]\frac{3}{4}[/tex]
Therefore, equation of the exponential function will be,
g(x) = [tex]12.(\frac{3}{4})^x[/tex]
at 5% commision, an agent received rs.32,500 by selling a second-hand car. At what price did he/she sell tha car?
Solution,
Let the price of car be X.
Rate(R)=5%
Here,
Commission % of price of car=32500
or,5% of X=32500
or,5/100*X=32500
or,X=32500*20
X=Rs 650000

x² - 36 = 0
solve for x
Answer: +6
Explanation: The equation x² - 36 = 0 is called a quadratic equation because he have a squared term as our highest power.
Our first step in this problem is to get the x²
term by itself by adding 36 to both sides.
That gives us x² = 36.
Next we must get the x by itself and in order to do
that we do the opposite of what is happening to x.
Since x is being squared, the opposite
of squaring is square rooting.
So to get x by itself, we square
root both sides of the equation.
On the left the square root of x² is x and on
the right, remember the following rule.
When square rooting both sides of
an equation, always use plus or minus.
So the answer to this problem would be +6.
So our solution to this equation is +6.

Please answer correctly !!!!! Will mark brainliest answer !!!!!!!!!!!!!!
Answer:
Step 2.
Step-by-step explanation:
When you have a coefficient on a side of the equation that you need to get rid of, you must divide by the number. For example, in the problem:
3(x+8)² = 75
Here, you need to divide both sides by '3' instead of multiplying, which was done instead. Then you get:
(x+8)² = 25.
Therefore, his mistake was made at Step 2.
Anne buys her store's art supplies from a wholesaler. She purchases 8 canvases that are 16 by 20 inches for $7.16
each. How much profit does Anne make on the sale of these 8 canvases?
OA. $35.92
OB. $45.63
OC.
$57.28
OD. $86.04
Answer:
OC. $57.28
Step-by-step explanation:
It depends on how much she sells them for.
Let's say Anne sells them for $x.
Then her profit is:
8x-(8*7.16)
=8x-57.28
To make a minimum to at least make even is $57.28 and sell for $7.16 a piece.
Anne makes a profit of $57.28 on the sale of these 8 canvases. which is the correct answer would be option (C).
What is the profit?The profit is equal to the difference between the selling price and the original cost price.
Anne purchases art supplies for her business from a wholesaler. She spends $7.16 on eight 16 by 20-inch canvases.
To calculate the profit that Anne makes on the sale of these 8 canvases, you need to know the price at which she sells them and the cost of buying them from the wholesaler. If the cost of each canvas is $7.16 and she buys 8 of them, the total cost of the canvases is :
⇒ 8 × $7.16
Apply the multiplication operation and we get
⇒ $57.28.
Therefore, she makes a profit of $57.28 on the sale of these 8 canvases.
Hence, the correct answer would be an option (C).
