Answer:
coffee is £1.80 per cup and tea is £1.40 per cup
Step by Step:
The question can be written algebraically, as:(a) 3t + 2c = 7.80(b) 5t + 4c = 14.20To work out the individual costs, we need to make one of the sets of variables equal. We can do this by multiplying the equation (a), giving (c):(a) 6t + 4c = 15.60(c) 5t + 4c = 14.20We can then subtract (c) from (a), giving:t = 1.40T can then be substituted into the initial equation (a), to work out the value of c:(3 x 1.40) +2c = 7.804.20 +2c = 7.802c = 3.60c = 1.80Finally we can check these values by substituting into (b):(5 x 1.40) + (4 x 1.80) = 7 + 7.2 = 14.20Then make sure to show your answers clearly, with units:coffee is £1.80 per cup and tea is £1.40 per cup

Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .
Step-by-step explanation:
The sum of Micah’s age and Aria’s age is 29. Aria is 5 years older than twice Micah’s age. Let x represent Micah’s age. The equation that can be used to find Micah’s age is
x + (x + 5) = 29.
x + (2 x + 5) = 29.
x + (2 x) = 29.
x + (2 x minus 5) = 29.
Answer:
x + (2x + 5) = 29
Step-by-step explanation:
Mica's age: x
Aria's age: 2x + 5
Sum of ages: x + (2x + 5)
Given sum of ages: 29
Equation: x + (2x + 5) = 29
Answer: x + (2x + 5) = 29

What is the theoretical probability that two coins flipped together will both land on tails?
What is the theoretical probability that two coins flipped together will both land on heads?
What is the theoretical probability that two coins flipped together will land on heads and tails?
Answer:
1.We say a coin is fair if it has probability 1/2 of landing heads up and probability 1/2 of landing tails up. What is the probability that if we flip two fair coins, both will land heads up? It seems plausible that each should be equally likely. If so, each has probability of 1/4.
2.The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
3.his states that the probability of the occurrence of two mutually exclusive events is the sum of their individual probabilities. As you can see from the picture, the probability of getting one head and one tail on the toss of two coins is 0

Breyelle is planning on purchasing a new sports-utility vehicle. The list price of the one she is most interested in buying is $32,000. This vehicle is expected to depreciate in value by 8.5% per year.
Which model could be used to calculate the daily depreciation for this vehicle?
V(t)=32,000(0.0233)^t
V(t)=32,000(0.9150)^t
V(t)=32,000(0.9767)t^t
V(t)=32,000(0.9998)^t
Answer:
V(t)=32,000(0.9767)t^t
Step-by-step explanation:
The correct model which could be used to calculate the daily depreciation for this vehicle is,
⇒ V (n) = 32,000 (0.915)ⁿ
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
We have to given that;
Breyelle is planning on purchasing a new sports-utility vehicle.
Here, The list price of the one she is most interested in buying is $32,000.
And, This vehicle is expected to depreciate in value by 8.5% per year.
Hence, the daily depreciation for this vehicle is,
V (n) = 32,000 (1 - 8.5%)ⁿ
V (n) = 32,000 (1 - 0.085)ⁿ
V (n) = 32,000 (0.915)ⁿ
Thus, The correct model which could be used to calculate the daily depreciation for this vehicle is,
⇒ V (n) = 32,000 (0.915)ⁿ

Step-by-step explanation:
a cylinder has a base diameter of 6 feet and a height of 2 feet . what is its volume in cubic feet, to the nearest tenths place?
The Volume of cylinder in cubic unit is 56.52 feet³.
What is Volume?'Volume' is a mathematical quantity that displays the amount of three-dimensional space occupied by an item or a closed surface in mathematics.
A volume is just the amount of space taken up by any three-dimensional solid. A cube, a cuboid, a cone, a cylinder, or a sphere are examples of solids.
We have,
Diameter = 6 feet
Radius = 6/2 = 3 feet
Height = 2 feet
So, the Volume of Cylinder
= πr²h
= 3.14 (3)² (2)
= 3.14(9) 2
= 3.14 (18)
= 56.52 feet³

Please help and hurry!! Ty!!
Answer:
a) Circumference of the circle = 56.52 in
b) Area of the circle = 254.34 in²
Step-by-step explanation:
Mr. Bernard needs to order boxes for his 18-inch diameter "Super Pizza."
Note that:
Pizza is Circular in shape
a) What is the approximate circumference of the Super Pizza? Use 3.14 for π. Show your work.
The formula for the circumference of a circle when given that diameter = πD
Where D = Diameter of the circle = 18 in
π = 3.14
Hence,
Circumference of the circle = 3.14 × 18 in
= 56.52 in
b) What is the approximate area of the Super Pizza? Use 3.14 for π. Show your work.
The formula for the area of a circle = πr²
Radius = Diameter/2
Diameter = 18 in
Radius = 18 in/2 = 9 in
The area of the circle = 3.14 × 9²
= 254.34 in²

Answer:
8: 90 degrees, 9: 165 degrees, 6: 81 degrees, 7: angles in the same segment are equal
Step-by-step explanation:
For question 8:
Notice how the line AB just barely touches the edge of the circle. We call this kind of line a tangent. The point O is at the center of the circle so the line OB is a radius. The angle between a tangent and a radius is always 90 degrees, so ABO is 90 degrees.
For question 9:
By the exact same logic as 8, ACO is also 90 degrees. The sum of interior angles in a 4 sided shape (a quadrilateral) is always 360 degrees. This means that 15 + 90 + 90 + x = 360 = 195 + x so x = 360 - 195 = 165
For question 6/7:
We use the theorem that the angles in the same segment are equal. This means that a is 81 degrees.

Check whether A{x:x2 =25 and 6x= 125} is an empty set or not
Given:
The set is
[tex]A=\{x:x^2=25\text{ and }6x=125\}[/tex]
To find:
Whether the given set is empty or not.
Solution:
A set is called empty set if it has no elements.
We have,
[tex]A=\{x:x^2=25\text{ and }6x=125\}[/tex]
We need to find the solutions of [tex]x^2=25[/tex] and [tex]6x=125[/tex]. The common solutions of these two equations are the elements of given set.
[tex]x^2=25[/tex]
[tex]x=\pm \sqrt{25}[/tex]
[tex]x=\pm 5[/tex]
[tex]x=5,-5[/tex] ...(i)
And,
[tex]6x=125[/tex]
[tex]x=\dfrac{125}{6}[/tex]
[tex]x\approx 20.83[/tex] ...(ii)
From (i) and (ii) it is clear that, there is no common value of x which satisfy both equations [tex]x^2=25[/tex] and [tex]6x=125[/tex].
Since there is no element in set A, therefore, the given get A is an empty set.
