Final answer:
To find numbers that multiply to 3.75, we can identify factor pairs like 1.5 and 2.5, or 1 and 3.75. Multiplying these pairs will result in 3.75.
Explanation:
To find which numbers multiplied together equal 3.75, we can look for factor pairs of the number 3.75. A factor pair is a set of two numbers that, when multiplied together, result in the given number. Since 3.75 can also be expressed as the fraction ⅓75/100 (or 15/4 in simplest form), we can find factor pairs by considering both whole numbers and decimals that multiply to give us the fraction equivalent.
For example, one obvious pair is 1.5 and 2.5. If we multiply 1.5 by 2.5, we get 3.75:
1.5 × 2.5 = 3.75
Another pair could be 1 and 3.75 as any number multiplied by 1 equals the number itself.
1 × 3.75 = 3.75
These are just two examples of factor pairs for 3.75, but there can be other combinations as well, particularly if we consider fractions or more decimal places.
3. Tim has 5/12 of a jar of blackberry jam and 3/8
of a jar of strawberry jam. Write 5/12 and 3/8
using a common denominator.
Answer:
The answers are 10/24 and 9/24.
Step-by-step explanation:
Given:
Tim has 5/12 of a jar of blackberry jam and 3/8 of a jar of strawberry jam.
Now, to write using a common denominator.
So, we get the multiples of denominator of the fractions to get common denominator:
12 - 12, 24, 36.
8 - 8, 16, 24.
Here we see that 24 is the common denominator.
Now, we multiply the numerator and denominator with the same number to get the common denominator of the fractions:
⇒ [tex]\frac{5}{12}=\frac{5\times 2}{12\times 2} =\frac{10}{24}[/tex]
⇒ [tex]\frac{3}{8}=\frac{3\times 3}{8\times 3} =\frac{9}{24}[/tex]
Therefore, the answers are 10/24 and 9/24.

she can spend no more than $65
before tax. She sees this price list in
the coffee shop.
Item
Dark Roast Coffee
Pumpkin Spice Coffee
Breakfast Tea
Price per pound
$7.50
$10.50
$23.50
Part A
Write a number in each blank to complete an inequality Lydia can use to find how
many pounds of Pumpkin Spice coffee, p, she can buy along with 2 pounds of
Dark Roast coffee.
Answer:
[tex]10.50p+15\leq 65[/tex]
[tex]p\leq \frac{100}{21}[/tex]
Step-by-step explanation:
Let p represent pounds of Pumpkin Spice coffee.
We have been given that Lydia is at a coffee shop and knows she can spend no more than $65 before tax. She sees this price list in the coffee shop.
Item Price per pound
Dark Roast Coffee $7.50
Pumpkin Spice Coffee $10.50
Breakfast Tea $23.50
Lydia wants to buy 2 pounds of Dark Roast coffee, so the cost of 2 pounds of Dark Roast coffee would be [tex]\$7.50\times 2=\$15[/tex].
We are told that cost of each pound of Pumpkin Spice coffee is $10.50, so cost of 'p' pounds of Pumpkin Spice coffee would be [tex]10.50p[/tex].
Since Lydia can spend no more than $65 before tax, so the cost of 2 pounds of Dark Roast coffee and 'p' pounds of Pumpkin Spice coffee must be less than or equal to 65.
We can represent this information in an inequality as:
[tex]10.50p+15\leq 65[/tex]
Therefore, our required inequality would be [tex]10.50p+15\leq 65[/tex].
[tex]10.50p+15-15\leq 65-15[/tex]
[tex]10.50p\leq 50[/tex]
Divide both sides by 10.50:
[tex]\frac{10.50p}{10.50}\leq \frac{50}{10.50}[/tex]
[tex]p\leq \frac{50*2}{10.50*2}[/tex]
[tex]p\leq \frac{100}{21}[/tex]
[tex]p\leq 4.76190[/tex]
Therefore, Lydia can buy less than or equal to [tex]\frac{100}{21}[/tex] pounds of Pumpkin Spice coffee.

Step-by-step explanation:
which of the following cannot be the probality of an event a)1/2 b) 10% c) 0.7. d) 3/2. which is the correct option with the solution
Answer:
D
Step-by-step explanation:
In probability,
a probability of 0 means that it is IMPOSSIBLE, sure that this event WILL NOT occur, ever. So, probability of anything less than 0 is not possible.
On the other hand, probability of 1 means that it is CERTAIN to happen. So, probabilty of anything greater than 1 can't happen.
So we can say:
0 <= Probability of an Event happening <= 1
Option A is 1/2, which is in the middle, so this is OKAY.
Option B is 10%, which is certainly close to 0 and between 0 and 1, so this is OKAY.
Option C is 0.7, which is close to 1 and greater than 0, so in between 0 and 1, certainly. So this is OKAY.
Option D is 3/2 which is 1.5, so this is GREATER THAN 1, so it can't ever be possible.
Option D is the correct choice.

f(x) = 4x+8
g(x) = x+3,
Find f(x)*g(x)
Answer:
4x^2+20x+24
Step-by-step explanation:
(4x+8)(x+3)=4x^2+8x+12x+24=4x^2+20x+24
The value of f(x) * g(x) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3
We have two functions -
f(x) = 4x + 8
g(x) = x + 3
We have to determine f(x)*g(x).
What is function in mathematics ?A function in mathematics is an expression with a independent variable (x) in it. The variable is called independent because it is not dependent on any value to get its value. Function also has a dependent variable (y) whose value depend on x. Ex -
y = f(x) = ax + d
According to the question, we have -
f(x) = 4x + 8
g(x) = x + 3
Therefore -
f(x) * g(x) = (4x + 8)(x + 3) = 4x(x + 3) + 8(x + 3) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3
Hence, the value of f(x) * g(x) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3

Jennifer feeds 5 times as many fish as Tony feeds
Jennifer [tex]=[/tex] 5 × Tony
[tex]=[/tex] 5 × 56
[tex]=[/tex] 280
Jennifer feeds total fishes is 280
Final answer:
Jennifer feeds 280 fish.
Explanation:
To find out how many fish Jennifer feeds, we need to perform a simple multiplication. Since Jennifer feeds 5 times as many fish as Tony, and Tony feeds 56 fish, we can write the following equation to represent the situation:
f = 5 × 56
We then multiply 56 by 5:
f = 280
So, Jennifer feeds 280 fish.
find the range of the function below if the domain is {-1,0,2}
f(x)=x^2 -2x +3
Answer:
{3, 6}
Step-by-step explanation:
f(x) is the same thing as y. f(x) or y are the values that are shown in the range.
The domain represents all possible values of x. Data must be in an (x, y) form, where any value of "y" would need a partner, "x".
Substitute all of the possible x-values into the formula to find all possible y-values (the range).
f(x) = x² - 2x + 3
f(-1) = (-1)² - 2(-1) + 3
f(-1) = 1 + 2 + 3
f(-1) = 6
f(x) = x² - 2x + 3
f(0) = (0)² - 2(0) + 3
f(0) = 0 - 0 + 3
f(0) = 3
f(x) = x² - 2x + 3
f(2) = (2)² - 2(2) + 3
f(2) = 4 - 4 + 3
f(2) = 3 Do not write repeated numbers
The possible y-values are 3 and 6.
Writ the range in set notation in the brackets {}. Order the numbers from least to greatest.
Range is {3, 6}.
The range of a function with a specified domain is equal to {3, 6}.
Range of the function:
The function is f(x) = x² - 2x + 3. Given the domain {-1, 0, 2}, we can find the corresponding range by evaluating the function at each point in the domain:
For x = -1: f(-1) = (-1)² - 2(-1) + 3 = 6.
For x = 0: f(0) = 0² - 2(0) + 3 = 3.
For x = 2: f(2) = 2² - 2(2) + 3 = 3.
The range of this function for the given domain is {3, 6}.

design with square and triangular tiles.
What is the area of the design? How did
you calculate your answer?
Step-by-step explanation:
With no photo of the design is imposible to calculate exactly the design area. However:
We know that the area of a square is:
[tex]A_{sq}=L^2[/tex] where L is the leght of the square's side
Also, the area a triangle is:
[tex]A_{tr}=\frac{h*b}{2}[/tex] where h is the height and b is the base (see the figure)

Rewrite it:
[tex]\dfrac{y^7\cdot y^5-1}{y^5}=\dfrac{y^{12}-1}{y^5}[/tex]
Consider the numerator:
[tex]y^{12}-1=(y^4)^3-1^3[/tex]
Use formula:

So,
[tex](y^4)^3-1^3=(y^4-1)((y^4)^2+y^4\cdot 1+1^2)=(y^4-1)(y^8+y^4+1)[/tex]
Now,
[tex]\dfrac{y^7\cdot y^5-1}{y^5}=\dfrac{(y^4-1)(y^8+y^4+1)}{y^5}=\dfrac{y^4-1}{y}\cdot \left(y^4+1+\dfrac{1}{y^4}\right)[/tex]

What does it mean to be a storehouse of value?
O
A. It serves as a valid currency.
O
B. The item is divisible and each unit is worth the same
O
C. Any item that can be traded for another item.
O
D. Any item that maintains its worth over time.
Final answer:
Being a storehouse of value means the item retains its worth over time, allowing it to be saved, stored, and reliably used later as a medium of exchange, like money or other assets with lasting value.
Explanation:
To be a storehouse of value means that the item, such as money, can retain its worth over some time. Unlike goods that may deteriorate, go out of style, or otherwise lose value, a storehouse of value allows individuals to save and store their wealth, retrieving it later with confidence that it will still be valuable.
Money is a common store of value since you do not need to spend it right away and can trust that even with the potential erosion of value due to inflation, it will remain a valid medium for future transactions.
Goods such as houses, artworks, or financial assets are also considered stores of value, but money is distinguished by its liquidity—being readily exchangeable for other goods or services. Although not perfect due to inflation, money's role as a medium of exchange in financial markets and aggregate expenditure makes it a convenient choice for storing value, especially when compared to the barter system.
In conclusion, option D - Any item that maintains its worth over time, accurately describes a storehouse of value.

Which of these equations and expressions will, when solved or simplified, give the length of the 5 pieces of wood Fulton cut?
Answer:
X=15 divided by 2
Step-by-step explanation:
Where X equals 5.
Answer:
[tex]5x + 2\frac{1}{2} = 15[/tex] and [tex]\frac{15 - 2\frac{1}{2} }{5}[/tex]
Step-by-step explanation:
Assume the length of each piece of wood is x feet.
We can say that the length of uncut board = (number of pieces × length of each piece) + length of leftover board, or [tex]15 = 5x + 2\frac{1}{2}[/tex].
Apply the Symmetric Property of Equality:
[tex]5x + 2\frac{1}{2} = 15[/tex]
Subtract [tex]2\frac{1}{2}[/tex] from both sides of the equation:
[tex]5x = 15 - 2\frac{1}{2}[/tex]
Divide both sides by 5: (See image)
Cancel out the common terms from the numerator and denominator:
[tex]x = \frac{5}{2}[/tex]
[tex]= 2\frac{1}{2}[/tex]

of N is y=-(x - 2)2 +6.
(a) Find the equation of M.
(2 marks)
Answer:
The equation of M is [tex]y=-(x+3)^2+6[/tex]
Step-by-step explanation:
we have that
The translation of M to N is
(-1,2) ----> (4,2)
The rule of the translation M to N is
(-1,2) ----> (x+a,y+b)
(-1,2) ----> (-1+a,2+b)
so
[tex]-1+a=4[/tex] ----> [tex]a=4+1=5[/tex]
[tex]2+b=2[/tex] ----> [tex]b=0[/tex]
The rule of the translation M to N is
(x,y) ----> (x+5,y)
The translation is 5 units right
I can say that the rule of the translation N to M is
(x,y) ----> (x-5,y)
we have the equation of N
[tex]y=-(x-2)^2+6[/tex]
Is a quadratic equation open downward
The vertex is (2,6)
Find the vertex of M
Applying the rule of the translation N to M to the vertex
(2,6) ----> (2-5,6)
(2,6) ----> (-3,6)
therefore
The equation of M is

Step-by-step explanation:
Given
[tex](8^{\frac{2}{3} } )^{4}[/tex]
Required
Simplify
To simplify this, we apply law of indices but first we start by solving the expression in bracket.
8 =2 * 2 * 2
8 = 2³
So, we substitute 2³ for 8
[tex](8^{\frac{2}{3} } )^{4}[/tex] becomes
[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex]
From law of indices
[tex]a^{n} = (a^{m})^{\frac{n}{m} }[/tex] ==> [tex](a^{m})^{\frac{n}{m} } = a^{n}[/tex]
So, [tex](2^{3})^{\frac{2}{3} } = 2^{2}[/tex]
At this point we have
[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex] = [tex](2^{2})^{4}[/tex]
Also, from law of indices
[tex](a^{m})^{n} = a^{m.n}[/tex]
So,
[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex] = [tex](2^{2})^{4}[/tex]
[tex](2^{2})^{4} = 2^{2*4}[/tex]
[tex](2^{2})^{4} = 2^{8}[/tex]
[tex](2^{2})^{4} = 256[/tex]
Hence,
[tex](8^{\frac{2}{3} } )^{4} = 256[/tex]
