(5, 1)
Step-by-step explanation:
Reflection across the x-axis negates the y-coordinate:
(x, y) ⇒ (x, -y) . . . . reflection across the x-axis
Rotation 90° CCW is the transformation ...
(x, y) ⇒ (-y, x) . . . . rotation 90° CCW
The two transformations together give ...
(x, y) ⇒ (y, x) . . . . reflection across the x-axis, then rotation 90° CCW
For point B, this gives ...
B(1, 5) ⇒ B'(5, 1)

Answer:
The container can hold 18 gallons
Step-by-step explanation:
Assume the container can hold x gallons
∵ The container is [tex]\frac{2}{3}[/tex] full with water
∵ It can hold x gallons
→ Multiply [tex]\frac{2}{3}[/tex] by x to find the number of gallons in the container
∴ The number of gallons in the container = [tex]\frac{2}{3}[/tex] x
∵ 4 gallons of water pouring out
∵ It is [tex]\frac{4}{9}[/tex] full
→ Multiply [tex]\frac{4}{9}[/tex] by x to find the number of gallons left in it
∴ The number of gallons left in the container = [tex]\frac{4}{9}[/tex] x
→ The difference between the numbers of gallons is 4 gallons
∵ [tex]\frac{2}{3}[/tex] x - [tex]\frac{4}{9}[/tex] x = 4
→ Subtract the terms of the left side
∴ [tex]\frac{2}{9}[/tex] x = 4
→ Multiply both sides by 9
∴ 2x = 36
→ Divide both sides by 18
∴ x = 18
∵ x represents the full of the container
∴ The container can hold 18 gallons

The word part meaning hundred is.
a. octo-
b. penta-
c. milli-
d. centi-
Answer:
centi
Step-by-step explanation:
Hey there!
When you see/hear the word “octo-”
(or “-octa”) think of ‘octagon’ and how they have ‘EIGHT SIDES’. So this means that prefix means 8; when you see/hear the word “penta-” think of ‘pentagon’ because it ‘FIVE SIDES’. So means that prefix means 5; When you see/hear the word “milli-” think of ‘one thousandths’ (this comes in handy when you’re working with DECIMALS and SOME MEASUREMENTS); when you see/hear “centi-” think of
centigrade.. you’ll learn about that in measurements as well.. it equals 100
Now that we had to break down the meaning of the prefixes we reached our answer:
The one that has the meaning for hundred is “centi- (option D)” would most likely be your answer
Answer: D. Centi- ☑️
Good luck on your assignment and enjoy your day!

a bricklayer needs to order 6300kg of building sand
Answer:
[tex]9\times 10^7\ \text{grains of sand}[/tex]
Step-by-step explanation:
Given that,
A bricklayer needs to order 6300kg of building sand.
1 grain of this sand weighs [tex]7\times 10^{-5}\ kg[/tex].
We need to find how many grains of sand are there in 6300 kg.
It can be just calculated as follows :
1 grain of sand = [tex]7\times 10^{-5}\ kg[/tex]
[tex]6300\ kg=\dfrac{6300}{7\times 10^{-5}}\\\\=9\times 10^7\ \text{grains of sand}[/tex]
or
= 90000000 grans of sand
So, 6300 kg is equal to [tex]9\times 10^7\ \text{grains of sand}[/tex].

Sam and Bethan share £54 in the ratio 5:4
Work out how much each person gets.
Answer:
Sam: $30; Bethan: $24
Step-by-step explanation:
Since the ratio is 5:4 Sam has to pay 5/9 of the total which is 54. To find how much he pays set up the equation like this.
[tex]\frac{x}{54} =\frac{5}{9}[/tex]
Cross Multiply
54(5)=9x
270=9x
Divide by 9
30=x
So Sam pays $30. To find out how much Bethan pays simply subtract 30 from 54
54-30=24
So Bethan pays $24

A football team plays a total of 30 matches in the league. If we know that it has lost in 3 10 of the matches and has taken 3 draws to find out how many matches he's lost.
Answer:
The team lost 9 matches
Step-by-step explanation:
Given
[tex]Matches = 30[/tex]
[tex]Lost = \frac{3}{10}[/tex] of the matches
[tex]Draw = 3[/tex]
Required
Determine the number of matches lost
From the question, we have:
[tex]Lost = \frac{3}{10}[/tex] of the matches
Mathematically, this is:
[tex]Lost = \frac{3}{10} * Matches[/tex]
Substitute 30 for Matches
[tex]Lost = \frac{3}{10} * 30[/tex]
[tex]Lost = \frac{3* 30}{10}[/tex]
[tex]Lost = \frac{90}{10}[/tex]
[tex]Lost = 9[/tex]
The team lost 9 matches
what calculation can be used to find the value of p in the equation p^3 =8
Cube Root
[tex] {p}^{3} = 8 \\ p = \sqrt[3]{8} \\ p = \sqrt[3]{ 2\times 2 \times 2} \\ p = 2[/tex]
Formula
[tex] {p}^{3} - 8 = 0[/tex]
Use the following formula.
[tex] {x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} )[/tex]
[tex](p - 2)( {p}^{2} + 2p + 4)[/tex]
The expression p²+2p+4 has the discriminant less than 0 ( D < 0 ).
Thus, remove the expression and leave only p-2
[tex]p - 2 = 0 \\ p = 2[/tex]
Substitution
The most obvious number that multiplies itself three times and equal 8 is 2.
Substitute p = 2
[tex] {p}^{3} = 8 \\ {2}^{3} = 8 \\ 2 \times 2 \times 2 = 8 \\ 8 = 8[/tex]
The equation is true, thus 2 is the answer.
Find three solution's to the linear equation 4x+y=20 using a table
Answer:
(-2, 28)
(-1, 24)
(0, 20)
Step-by-step explanation:
You can plug any numbers in for x, and solve for y.
Example: 4(-2) + y =20 multiply 4 and -2
-8 + y = 20 add 8 to both sides
y = 28
You can then do this for the rest of the numbers. Here is a table below:

La suma de dos números es 81. La diferencia de los mismos dos números es 33. Escribe un sistema de ecuaciones para representar esta situación. Luego encuentra los números.
Answer:
a) Escribe un sistema de ecuaciones para representar esta situación.
x + y = 81 ...... Ecuación 1
x - y = 33 ....... Ecuación 2
b) Los dos números son: 57 y 24
Step-by-step explanation:
Estamos tratando con 2 números
Dejar
El primer número = x
El segundo número = y
La suma de dos números es 81.
x + y = 81 ...... Ecuación 1
La diferencia de los mismos dos números es 33.
x - y = 33 ....... Ecuación 2
Escribe un sistema de ecuaciones para representar esta situación.
x + y = 81 ...... Ecuación 1
x - y = 33 ....... Ecuación 2
Resolvemos estas ecuaciones usando el método de eliminación
Restamos la ecuación 2 de la ecuación 1 para eliminar
2y = 48
y = 48/2
y = 24
Resolver para x usando la Ecuación 1
x + y = 81 ...... Ecuación 1
x + 24 = 81
x = 81 - 24
x = 57
Por lo tanto, los dos números son: 57 y 24
