At a bake stall there is a large square pan of chocolate brownies. Customers can buy any fraction of the pan of brownies they like.The first customer bought 1/2 of the pan of brownies. The second customer bought 5/6 of what was left of the pan of brownies. What fraction of the whole pan did the second customer buy
Answer: 5/12
Step-by-step explanation:
Since the first customer bought 1/2 of the pan of brownies. This means that the pan of brownies left will be:
= 1 - 1/2
= 1/2
The The second customer bought 5/6 of what was left of the pan of brownies, the fraction that the second customer bought will be:
= 5/6 × 1/2
= 5/12
Answer:
5/12
Step-by-step explanation:
At a bake stall there is a large square pan of chocolate brownies. Customers can buy any fraction of the pan of brownies they like.
The first customer bought 1/2 of the pan of brownies.
The amount of brownies that was left over is given as:
1 - 1/2 = 1/2 brownies left ove
The second customer bought 5/6 of what was left of the pan of brownies.
The amount of brownies the second customers bought is calculated as:
5/6 of 1/2
= 5/6 × 1/2
= 5/12
What fraction of the whole pan did the second customer buy

Find each length
5. the length of the hypotenuse of a 45 degree- 45 degree- 90 degree triangle with a leg of 12
6. the length of the longer leg of a 30 degree- 60 degree- 90 degree triangle with a hypotenuse of 14, where theta = 60 degrees
Answer:
12√2
7√3
Step-by-step explanation:
The length of the hypotenuse of a 45°-45°-90° triangle with a leg of 12 is 12√2 and the length of longer leg is 7√3 for 30°-60°-90° triangle.
What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
Ratio of the sides of a 45°-45°-90° triangle is 1 : 1 : √2.
That is,
If sides opposite to 45° = x, then the side opposite to 90° = √2 x
That is, length of the hypotenuse = √2 x
Given length of a leg = 12
Length of the hypotenuse = √2 × 12 = 12√2.
Ratio of the length of sides of 30°-60°-90° triangle is 1 : √3 : 2.
That is,
Length of side opposite to 30° = x
Length of side opposite to 60° = √3 x
Length of side opposite to 90° = 2x (Hypotenuse)
We have to find the longer leg, that is √3 x.
Length of hypotenuse = 14
2x = 14 ⇒ x = 7
Length of longer leg = 7√3
Hence the lengths are 12√2 and 7√3.

(4a^3+5a^2-a+1)-(5a-2a^3+3)
Answer:
6a^3 + 5a^2 - 6a - 2
Step-by-step explanation:
(4a^3 + 5a^2 - a + 1) - (5a - 2a^3 + 3)
Combine like terms
4a^3 - (-2a^3) = 6a^3 (- times - = +)
-a - 5a = -6a
1 - 3 = -2
Now combine the answers in standard form (don't forget the 5a^2)
6a^3 + 5a^2 - 6a - 2

What is the degree of the polynomial? 5x^5 - 6x^6 + 2
Answer:
6
Step-by-step explanation:
Degree of a polynomial is the degree of the monomial with the greatest degree, which in this case is 6x^6, so the degree of this polynomial is 6 because the x is raised to the 6th degree.
The degree of the polynomial 5x⁵-6x⁶ + 2 is 6.
What is a polynomial?An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Given:
The polynomial,
5x⁵-6x⁶ + 2.
Here, we have the variable x.
And the highest power of a variable is a degree of a polynomial.
So, the degree of polynomial is 6.
Therefore, the degree of the polynomial is 6.

how do you know you have a direct variation in the relationship between two quantities?
Answer:
Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.

Considerate of these three numbers express and scientific notation 8.2×10 to the -3rd power 5.2×10 to the $96 and 4.1 times since I'm -6 hours which number is the greatest invite how many times does it rather than smallest number
Answer:
[tex]8.2 * 10^{-3}[/tex] is the greatest
2000 times greater
Step-by-step explanation:
Given
[tex]8.2 * 10^{-3}[/tex]
[tex]5.2 * 10^{-6}[/tex]
[tex]4.1 * 10^{-6}[/tex]
Solving (a): The greatest of the numbers
First, we convert them to decimals:
[tex]8.2 * 10^{-3} = 0.0082[/tex]
[tex]5.2 * 10^{-6} = 0.0000052[/tex]
[tex]4.1 * 10^{-6} = 0.0000041[/tex]
By comparing the decimal numbers, the highest is: 0.0082.
Hence,
[tex]8.2 * 10^{-3}[/tex] is the greatest
Solving (b): How many times greater than the smallest
In (a) above:
The greatest is: [tex]8.2 * 10^{-3}[/tex]
By comparing the decimal numbers,
The smallest is: 0.0000041 i.e. [tex]4.1 * 10^{-6}[/tex]
The number of times the greatest is greater than the smallest is:
[tex]Number = \frac{8.2 * 10^{-3}}{4.1 * 10^{-6}}[/tex]
[tex]Number = \frac{0.0082}{0.0000041}[/tex]
[tex]Number = 2000[/tex]
Hence, it is 2000 times greater

Sum of [tex]\frac{9}{10}[/tex] and [tex]\frac{5}{6}[/tex] is equal to [tex]\boldsymbol{\frac{26}{15}}[/tex].
What is summation?A summation, also known as a sum, is the outcome of adding numbers or quantities arithmetically. A summation always has an even number of terms.
Summation is the adding of a series of numbers known as addends or summands; the result is their sum or total.
Sum of [tex]\frac{9}{10}[/tex] and [tex]\frac{5}{6}[/tex] [tex]=\frac{9}{10} +\frac{5}{6}[/tex]
[tex]=\frac{27+25}{30}\\\\ =\frac{52}{30}\\\\ =\frac{26}{15}[/tex]

Need answer ASAP I’m timed What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
Answer:
17
Step-by-step explanation:
(7, 8) (-8, 0)
First find how much the point moved in y to the second point.
8-0=8
So one side is 8.
Then find how much it moved in x. 7-(-8)=15
So the other side is 15
This will give you 2 sides of a triangle where one sides lenght is 8 the other is 15. Use the pythagoras theorem which is x squared plus y squared = c squared
8^2+15^2=c^2
64+225=c^2
289=c^2 Take the square root of both sides to solve for C
√289= √C^2
17 = c

If there are 1.15 land miles in a nautical mile, how
many land miles are there in 10 nautical miles?
Answer:
11.5
Step-by-step explanation: Since there is 1.15 land miles in one nautical mile you multiply 1.15 by 10 to find how many land miles are in 10 nautical miles.
The number of land miles there in 10 nautical miles will be 11.5.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.
If and only if the number being multiplied is more than one, multiplication produces a resultant number that is significantly larger than the original number.
As per the given,
One nautical mile = 1.15 land miles
In 10 nautical miles = 1.15 x 10 = 11.5 land miles
Hence "The number of land miles there in 10 nautical miles will be 11.5".
