Answer:
a) 30 pages b) 22.5 or 45/2 c)50/3 or 16.67 d) 1/8 e) 73/3 or 24.33 f)1/9 g) 1/27
Step-by-step explanation:
a) If Natalie has read 3/4 then all that's left is 1/4 of the book to read a whole book since 3/4+1/4=4/4=1
1/4 of 120=30 pages
b) One half of 45 is the same as dividing it by two or multiplying by 1/2.
1/2*45=45/2 =22.5
c) One third of 50, is the same of multplying by 1/3 then 1/3*50≈16.67
d) Take a look back at letter b. One half (1/2) of 1/4 is :
[tex]\frac{1}{2}*\frac{1}{4}=\frac{1}{8}[/tex]
e) One third of something, is 1/3 times something like previous cases above so 1/3*73=73/3≈24.33
f) One third of One third, is 1/3 times 1/3:
[tex]\frac{1}{3}*\frac{1}{3}=\frac{1}{9}[/tex]
g) One third of 1/9 is 1/3 times 1/9:
[tex]\frac{1}{3}*\frac{1}{9}=\frac{1}{27}[/tex]
Do not forget the rules of multiplying fractions. Numerator times Numerator, Denominator times Denominator. When we read a third, half,.. of this means one half times

What is the solution of 3+ (x-2)/(x-3) <=4
X<3
X<=3
X>3
X>=3
Answer:
A. X < 3.
Step-by-step explanation:
We have the equation, [tex]3 + \frac{x-2}{x-3} \leq 4[/tex]
Adding -4 on both sides, we get,
[tex]\frac{x-2}{x-3} -1 \leq 0[/tex]
i.e. [tex]\frac{x-2-x+3}{x-3} \leq 0[/tex]
i.e. [tex]\frac{1}{x-3} \leq 0[/tex]
So, we have the inequality [tex]\frac{1}{x-3} \leq 0[/tex].
Its critical points are given by x-3 = 0 which implies x = 3.
Now, we will find the region among the two [tex]( - \infty , 3 )[/tex] and [tex]( 3 , \infty )[/tex] that satisfies the inequality [tex]\frac{x-2}{x-3} -1 \leq 0[/tex]
Substitute x = 2 in the above inequality, we get -1 < 0, which is true. Again, substitute x=4 gives 1 < 0, which is false.
As x=4 lie in the region [tex]( 3 , \infty )[/tex] , it cannot be the solution of the given inequality.
So, the solution of the given inequality is the region [tex]( - \infty , 3 )[/tex] .i.e. x < 3.
Hence. option A is correct.

Nial is signing a lease for an apartment that rents for $1020/month. How much will he pay to move in if he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent?
2040
$2448
$2652
$2856
Answer:
Option (c) is correct.
He pays $ 2652.
Step-by-step explanation:
Given : Nial is signing a lease for an apartment that rents for $1020/month.
We have to find the amount he pay to move in if he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent.
Since, given he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent.
Given monthly rent is $ 1020
That is 60% of his monthly rent = [tex]\frac{60}{100}\times 1020=612[/tex]
Thus, total amount he needs to pay is first month rent + last month rent + 60% of his monthly rent.
That is 1020 + 1020 + 612 = 2652.
Thus, He pays $ 2652.

A population of 55 foxes in a wildlife preserve doubles in size every 14 years. The function y equals 55 times 2 Superscript x , where x is the number of 14-year periods, models the population growth. How many foxes will there be after 28 years?
Final answer:
To find the fox population after 28 years, we use the function y = 55 × 2^x, with x = 2 because 28 years is two 14-year periods. After calculating 2^2 and multiplying by 55, we find that there will be 220 foxes.
Explanation:
To calculate the number of foxes in a wildlife preserve after 28 years, given that the population doubles every 14 years, we start with the function y = 55 × 2^x, where x represents the number of 14-year periods.
Since 28 years is equivalent to 2 periods of 14 years, we will substitute x with 2:
Write down the equation substituting x with 2: y = 55 × 2^2.Calculate the exponent: 2^2 = 4.Multiply the base population by 4: 55 × 4 = 220.Therefore, after 28 years, there will be 220 foxes in the wildlife preserve.
In a hockey club there are 5% more boys than there are girls. If there is a total of
246 members in the club, what is the number of boys and the number of girls?
HOW WOULD I WORK THIS OUT
The number of boys and the number of girls are 126 and 120 respectively.
What is percentage?A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.
Given that, there are 5% more boys than there are girls, there is a total of
246 members in the club,
We need to find the number of boys and the number of girls,
Here we will use the concept of percentage as well as equation solving,
Let the number of girls be x, so, the number of boys = 105% of x = 1.05x
According to the question,
x+1.05x = 246
2.05 x = 246
x = 120
1.05x = 126
Hence, the number of boys and the number of girls are 126 and 120 respectively.

The value of the given expression m∠a + m∠c is 233 degrees and this can be determined by using the given data.
Given :
Quadrilateral ABCD.Angle B is 95 degrees.Angle D is 32 degrees.The following steps can be used in order to determine the value of the given expression:
Step 1 - The sum of interior angles of the quadrilateral is 360 degrees.
Step 2 - According to the given data, angle B is 95 degrees and angle D is 32 degrees.
Step 3 - So, the value of the given expression can be calculated as:

What is the set of all possible outcomes of a probability experiment?
The set of all possible outcomes of a probability experiment is called the sample space. It can be represented as a list, a table, or using set notation.
Explanation:The set of all possible outcomes of a probability experiment is called the sample space. It is denoted by the symbol Ω. The sample space can be represented as a list, a table, or using set notation.
For example, if we are flipping a fair coin, the sample space would be {H, T}, where H represents heads and T represents tails.
In another example, if we were rolling a fair six-sided die, the sample space would be {1, 2, 3, 4, 5, 6}.

My jar has 25 dimes and some quarters, nickels, and pennies. The number of quarters plus dimes equals the number of pennies. I have 4 nickels for every dime and 2 pennies for every nickel. How many quarters are there? A. 175 B. 150 C. 125 D. 75
Answer:
Quarters = 175
Step-by-step explanation:
Let the number of dimes in the jar = 25
number of Nickels = n
number of quarters = q
number of pennies = p
Now we will form the equation
Number of quarters plus dimes equal the number of pennies.
q + 25 = p --------(1)
You have 4 nickles for every dime
n = 4d
n = 4 × 25 = 100
and you have 2 pennies for every nickels
p = 2n
p = 2 × 100 = 200
Now we replace p = 200 in equation (1)
q + 25 = 200
q = 200 - 25
q = 175
Option A. 175 will be the answer.
