What is the smallest positive number that is prime and 10 less than a perfect square?
Answer:
The problem states that the answer cannot be a perfect square or have prime factors less than $50$. Therefore, the answer will be the product of at least two different primes greater than $50$. The two smallest primes greater than $50$ are $53$ and $59$. Multiplying these two primes, we obtain the number $3127$, which is also the smallest number on the list of answer choices. So we are done, and the answer is $\boxed{\textbf{(A)}\ 3127}$.

Christine wants to buy strawberries and raspberries to bring to a party. Strawberries cost $1.65 per pound and raspberries cost $2.25 per pound. She only has $15 to spend on berries. Which inequality represents the situation where she buys x pounds of strawberries and y pounds of raspberries?
Answer:
1.65x + 2.25y ≤ 15
Step-by-step explanation:
Strawberries = $1.65 per pound Raspberries = $2.25 per pound
Amount with Christine = $15
Let
pounds of strawberries = x
pounds of raspberries = y
PxQx + PyQy ≤ 15
1.65x + 2.25y ≤ 15
The inequality which represent the situation where she buys x pounds of strawberries and y pounds of raspberries is 1.65x + 2.25y ≤ 15
1.65x + 2.25y less than or equal to 15

One year, Mr James travels 8 x 10^3 miles for his job. The next year he traveled 1 x 10^4 miles. How many more miles did he travel the second year than he did the first year? Please give me the answer and explain ToT
Answer:
2 000 miles
Step-by-step explanation:
In the first year, Mr James travels 8 x [tex]10^{3}[/tex] miles = 8 000 miles.
The second year, he traveled 1 x [tex]10^{4}[/tex] miles = 10 000 miles.
Comparing the distance covered in the two years,
10 000 miles - 8 000 miles = 2 000 miles
Therefore, Mr James travels 2 000 more miles in the second year than he did the first year.
Let's assume that Mr James conveys himself to his place of work all through the first year in his private car. But in the second year, there were some days in which the car was not available. So he had to go for his job by public transportation. This itch during those days, could cause an increase in the distance covered from his home to his place of work for the second year.

You borrow $350 from your aunt and agree to repay her $400 ($350 principal + $50 interest) in 18 months. What interest rate (using simple interest, and to the nearest tenth) are you paying?
Answer:
The interest rate is 0.79% per month.
Step-by-step explanation:
Present value of borrowed amount = $350
Future value of borrowed amount = $400
Interest amount = $50
Time duration = 18 months or 1.5 years
Now we have to find the rate of interest by using the above information. Here below is the calculation of interest rate.
Interest rate = P×R×T
50 = 350 × R×18
R = 0.007936
Or, R = 0.79% per month.
27x + 45y and 7(9x + 7y) are these equivalent?
Answer:
No
Step-by-step explanation:
If you want to know whether they are equivalent or no, we will first have to find the value of both.
[tex]27x+45y[/tex]
Since there aren't any like terms here, your answer would be
[tex]27x+45y[/tex]
Let's solve for next one.
[tex]7(9x+7y)[/tex]
Let's add in parenthesis to 7.
[tex](7)(9x+7y)[/tex]
Now we will separate everything. And also you will have to add.
[tex](7)(9x)+(7)(7y)[/tex]
Now that we added we got our answer.
[tex]63x+49y[/tex]
Both values were not the same, so therefore, your answer is no, they are not equivalent.
Hope this helps!

The sorting of the dataset and the information from the five number summary, which includes the three quartiles and the minimum and maximum values indicates that we get;
1. 2.8, 4, 4.3, 6, 7.5, 8.5, 9, 11.6, 12, 12.1
2. The interquartile range is; 7.745
What is the five number summary of interquartile range of a data set?The five number summary includes the first, second and third quartiles, Q₁, Q₂, and Q₃, and maximum and minimum values of the dataset, which serves to describe the characteristics of the data.
here, we have,
1. The sorted data from least to greatest can be presented as follows;
2.8, 4, 4.3, 6, 7.5, 8.5, 9, 11.6, 12, 12.1
Therefore, the original data in the question is already sorted from least to the greatest
2. The interquartile range, IQR, is the the difference between the third quartile, Q₃, and the first quartiles, Q₁, of the data.
IQR = Q₃ - Q₁
The dataset indicates that we get;
The number of datapoints in the dataset, n = 10
The first quartile = The (N + 1)/4 percentile value
First quartile, Q₁ = (10 + 1)/4 × 10 = The 2.75th value
The 2.75th value is the value 0.75 = 3/4 larger than the 2nd value, which can be found as follows;
Q₁ = The 2.75th value = 4 + (4.3 - 4) × (3/4) = 4.225
The third quartile, Q₃ = The (N + 1) × (3/40th value, therefore;
Q₃ = The (10 + 1) × (3/4)th value = The 8.25th value (The value 0.25th more than the 8th value )
Q₃ = 11.6 + (12 - 11.6) × 0.25 = 11.7
The interquartile range, IQR = 11.7 - 4.225 = 7.475
The interquartile range = 7.475

Answer:
a = [tex]\frac{11}{7}[/tex] ; b = [tex]\frac{6}{7}[/tex]
Step-by-step explanation:
[tex]\frac{3 + \sqrt{2}}{3 - \sqrt{2} } = a + b\sqrt{2} \\\\[/tex]
Rationalising [tex]\frac{3 + \sqrt{2}}{3 - \sqrt{2} }[/tex] gives :-
[tex]\frac{3 + \sqrt{2}}{3 - \sqrt{2} } = \frac{(3 + \sqrt{2})(3 + \sqrt{2})}{(3 - \sqrt{2})(3 + \sqrt{2}) } = \frac{(3 + \sqrt{2})^2}{3^2 - (\sqrt{2})^2 } = \frac{11 +6\sqrt{2} }{7}[/tex]
Comparing [tex]\frac{11 + 6\sqrt{2} }{7}[/tex] with [tex]a + b\sqrt{2}[/tex] gives
a = [tex]\frac{11}{7}[/tex] & b = [tex]\frac{6}{7}[/tex]
Answer:
[tex]\frac{11}{7}[/tex] + [tex]\frac{6}{7}[/tex] [tex]\sqrt{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{3+\sqrt{2} }{3-\sqrt{2} }[/tex]
Multiply the numerator/ denominator by the conjugate of the denominator.
The conjugate of 3 - [tex]\sqrt{2}[/tex] is 3 + [tex]\sqrt{2}[/tex] , thus
= [tex]\frac{(3+\sqrt{2})(3+\sqrt{2}) }{(3-\sqrt{2})(3+\sqrt{2}) }[/tex] ← expand numerator/ denominator using FOIL
= [tex]\frac{9+6\sqrt{2}+2 }{9-2}[/tex]

The next model of a sports car will cost 12.9% more than the current model. The current model costs $35,000. How much will the price increase in dollars
Answer:
The price increase in dollars= $4,515
Step-by-step explanation:
Cost of the next model = cost of the current model + 12.9% cost of the current model
Cost of the current model = $35,000
12.9% cost of the current model
= 12.9/100 × $35,000
= 0.129 × $35,000
= $4,515
Cost of the next model = cost of the current model + 12.9% cost of the current model
= $35,000 + $4,515
= $39,515
Cost of the next model = $39,515
The price increase in dollars= next model price - current model price
=$39,515 - $35,000
= $4,515
The price increase in dollars = $4,515
Please solve for a ! 24+5a=-a+6(5a-4)
Answer:
a = 2
Step-by-step explanation:
First of all you should remove parentheses by using distribution
24 + 5a = - a + 30a - 24
Then you should collect all like terms
24 + 5a = 29a - 24
After you should move the terms so the variables are only on one side.
5a - 29a = -24 - 24
Collect like terms
-24a = -48
After dividing both sides you get
a = 2
A scientist has two kinds of solutions. The first solution is Solution A, which is an $80\%$ acid solution. The second solution is Solution B, which is a $30\%$ acid solution. (a) Find the amount of Solution A (in mL) that must be added to $500$ mL of Solution B in order to produce a $70\%$ acid solution. (b) Find the amount of Solution A and Solution B (in mL) that can be combined in order to form a $100$ mL solution that is $50\%$ acid. (c) Does there exist a combination of Solution A and Solution B that is $90\%$ acid?
Answer:
Step-by-step explanation:
a ) Let the volume required be v .
v x .8 + 500 x .3 / ( v + 500 ) = .7
.8 v + 150 = .7 v + 350
.1 v = 200
v = 2000 mL
b )
Let the volume of solution A required be v . The volume of solution of B required will be 100 - v
v x .8 + ( 100 - v ) x .3 / 100 = .5
.8 v + 30 - .3 v = 50
.5 v = 20
v = 40 mL
volume of solution B = 60 mL .
c )
It is not possible because 90 % is more than 80 % the concentration of solution A . Any mixture will have concentration less than 80 % .
volume of solution B = 60 mL
