Stephen, Paul & Bridget share some money in the ratio 3 : 4 : 2. In total, Stephen and Bridget receive £50. How much does Paul get?
Answer:
The money receive by Paul is [tex]\pounds 40[/tex].
Step-by-step explanation:
Given as :
The ratio of share of money among three people as
Stephen : Paul : Bridget = 3 : 4 : 2
The total money receive by Stephen and Bridget = [tex]\pounds 50[/tex]
Let The money receive by Stephen = 3 x
Let The money receive by Paul = 4 x
Let The money receive by Bridget = 2 x
Now, According to question
The total money receive by Stephen and Bridget = [tex]\pounds 50[/tex]
I.e 3 x + 2 x = [tex]\pounds 50[/tex]
i.e 5 x = [tex]\pounds 50[/tex]
∴ x = [tex]\frac{\pounds 50}{5}[/tex]
x = [tex]\pounds 10[/tex]
So, The money receive by Stephen = 3 × [tex]\pounds 10[/tex] = [tex]\pounds 30[/tex]
Let The money receive by Paul = 4 × [tex]\pounds 10[/tex] = [tex]\pounds 40[/tex]
Let The money receive by Bridget = 2 × [tex]\pounds 10[/tex] = [tex]\pounds 20[/tex]
Hence The money receive by Paul is [tex]\pounds 40[/tex]. Answer

a first plus twice a second number is one. twice the first number plus the second totals fourteen.
Answer:
First Number = 9
Second Number = -4
Step-by-step explanation:
Let the first number be "x" and the 2nd number be "y"
First number PLUS twice 2nd is 1, so we can write:
x + 2 y = 1
Twice First number PLUS the 2nd number is 14, so we can write:
2x + y = 14
We can write:
y = 14 - 2x
We put this into 1st equation and solve for x:
x + 2y = 1
x + 2(14 - 2x) = 1
x + 28 - 4x = 1
-3x = -27
x = 9
And now y:
y = 14 - 2(x)
y = 14 -2(9)
y = 14 - 18
y = -4
First Number = 9
Second Number = -4

Sadie finished her math test in sixteen minutes less than three times the amount of times it took her friend Laura to finish.if their combined times was 1 hour and 8 minutes,how long did it take Sadie?
Answer:
Sadie took 47 minutes to finish her test.
Step-by-step explanation:
Let Laura's time be x minutes.
Then we have:
x + 3x - 16 = 68
4x = 84
x = 21 minutes.
So Sadie took 3(21) - 16 = 63-16
= 47 minutes.
10. A square picture has a 1-inch frame around it. If the
area of the frame alone is 80 in.2, what is the area of the
picture?
Answer:
361 sq, inches.
Step-by-step explanation:
Let us assume that the dimensions of the square picture are P in × P in.
So, the area of the picture alone is, A = P²
Now, if the photo has a frame of 1 inch wide, then the dimensions of the photo with frame are (P + 2) in × (P + 2) in.
So, the area of the photo with frame is A' = (P + 2)(P + 2) = (P + 2)²
Now, the area of the frame alone is 80 sq. inches.
Hence, A' - A = 80
⇒ (P + 2)² - P² = 80
⇒ 4P + 4 = 80
⇒ 4P = 76
⇒ P = 19 inches.
So, the area of the picture is = 19² = 361 sq. inches. (Answer)
361 sq, inches.

Determine the probability of being dealt 3 tens from a standard deck of 52 cards when 3 cards are dealt
Answer:
A standard deck contains 52 cards with 4 suits and hence 4 tens. The probability of being dealt 3 tens is thus 4/52 x 3/51 x 2/50. The denominator decreases as one card is removed from the deck each time. If the removed card is replaced, there would be no need for the decrease in the denominator.

12. For triangle MNP shown, find the value of x
and the measure of each of the three angles
M
/(2x – 1)º (2x + 1))
Answer:
[tex]x=36\°\\\angle P=71 \°,\angle N=73 \°,\angle M=36 \°[/tex]
Step-by-step explanation:
Given:
The triangle is shown below.
We know that the sum of all interior angles of a triangle is equal to 180°.
Therefore,
[tex]\angle M+\angle N+\angle P=180 \°\\\\x+2x+1+2x-1=180\°\\\\5x=180\°\\\\x=\frac{180}{5}\\\\x=36\°[/tex]
Now, plugging the value of 'x' in each angle measure and determining its values. We get:
[tex]\angle M=x=36\°\\\angle P=2x-1=2(36)-1=72-1=71\°\\\angle N=2x+1=2(36)+1=72+1=73\°[/tex]
Therefore, the value of 'x' is 36° and the measure of the three angles are 36°, 71° and 73°.

The owner of a new restaurant is ordering tables and chairs. he wants to have only tables for two and tables for 4. the total number of people can be seated in rest is 120, then write an equation to represent the situation. What do the variables represent?
Answer:
4 M + 2 N = 120
Step-by-step explanation:
If we name "M" the number of tables for four people, and "N" the number of tables for two people, then the total number of people to be seated using M tables (of four people) would be the product "4 * M".
Similarly, the total number of people to be seated if the owner has N number of two person tables, would be: "2 * N".
Therefore, if the owner has M four people tables and N two person tables, the total number of people seated at the restaurant would be the addition:
4 * M + 2 * N. Since he wants this number to be 120, we complete the equation making this expression equal to 120:
4 * M + 2 * N = 120
The equation that represents this situation is 2x + 4y = 120, where x represents the number of tables for two and y represents the number of tables for four. Thus, this mathematical equation reflects the owner's seating arrangement plans for his restaurant.
Explanation:Let's use x to represent the number of tables for two and y to represent the number of tables for four. Since each table for two can seat 2 people and each table for four can seat 4 people, the total number of people that can be seated is 2x + 4y. The owner of the restaurant wants to seat a total of 120 people, so the equation that represents this situation is 2x + 4y = 120.
In this equation, x and y are the variables. The x value represents the number of tables for two and the y value represents the number of tables for four.

Answer:
473 turnips
Step-by-step explanation:
well if its 1 to 1 that means how ever meany you have of one you will have the same exact amount of the other food
473x1 = 473x1
Final answer:
To find the number of turnips, set up a proportion using the given ratio and cross multiply to solve for the number of turnips.
Explanation:
To find the number of turnips, we can set up a proportion using the given ratio:
Number of potatoes / Number of turnips = Ratio of potatoes to turnips.
Since the ratio of potatoes to turnips is 1:1, the proportion will be:
473 / Number of turnips = 1 / 1.
To solve for the number of turnips, cross multiply:
473 * 1 = Number of turnips * 1.
Number of turnips = 473.
Therefore, there are 473 turnips in this scenario.

Answer:
(B) π/12 + π/6 k
Step-by-step explanation:
Points of inflection are where f"(x) = 0 and changes signs.
f(x) = cos²(3x)
f(x) = (cos(3x))²
f'(x) = 2 (cos(3x))¹ × -sin(3x) × 3
f'(x) = -6 sin(3x) cos(3x)
Using double angle formula:
f'(x) = -3 sin(6x)
f"(x) = -3 cos(6x) × 6
f"(x) = -18 cos(6x)
0 = -18 cos(6x)
0 = cos(6x)
6x = π/2 + 2πk or 6x = 3π/2 + 2πk
We can simplify this to:
6x = π/2 + πk
x = π/12 + π/6 k

A box of 42 chocolates contains milk and dark chocolates in the ratio of 3:4. How many chocolates of each type there are?
Answer:
18 Milk Chocolates: 24 dark chocolates
Step-by-step explanation:
The total number of chocolates are 42
So you have Milk: Dark, in the ratio 3:4
You do 3+4 which = 7
You then divide the total ratio outcome by the total number
So you do, 42/7 =6
You then do 6 and put this into the ratio
So you do, 3x6 and 4x6, which = 18 and 24
To check if your answers correct add the ratio outcomes
And If you add 18 and 24 together, you should get your beginning total of 42

Answer
______________
The same solution of the given system of equations will be same as the solution of below system of equations;
⇒ 8x + 4y = −4
17x + 2y = −28
Option A is true.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The System of equation is,
6x + 2y = - 6 ..(i)
3x - 4y = - 18 ..(ii)
Now,
Solve the given system of equation as;
The System of equation is,
6x + 2y = - 6 ..(i)
3x - 4y = - 18 ..(ii)
By equation (i);
6x + 2y = - 6
2(3x + y) = - 6
3x + y = - 3 ..(iii)
Subtract equation (ii) from (iii), we get;
3x - 4y - (3x + y) = - 18 - (-3)
3x - 4y - 3x - y = - 18 + 3
- 5y = - 15
y = 3
And, By equation (i), we get;
6x + 2y = - 6
6x + 2 × 3 = - 6
6x + 6 = - 6
6x = - 6 - 6
6x = - 12
x = - 2
Thus, The solution of given system of equation are;
x = - 2 and y = 3
Now,
Substitute the value of x and y in all the given options and find the same solution of given system of equation as;
A: 8x + 4y = −4
17x + 2y = −28
Substitute the value of x = - 2 and y = 3;
8x + 4y = −4
8 × - 2 + 4 × 3 = - 4
- 16 + 12 = - 4
- 4 = - 4
17x + 2y = −28
17 × - 2 + 2 × 3 = - 28
- 34 + 6 = - 28
- 28 = - 28
Thus, This system of equation has same solution.
Therefore, The same solution of the given system of equations will be same as the solution of below system of equations;
⇒ 8x + 4y = −4
17x + 2y = −28
Option A is true.
