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

Find the equation of the line through (-1, 3) and (5,3)
Given:
A line passes through (-1, 3) and (5,3).
To find:
The equation of the line.
Solution:
The line passes through (-1, 3) and (5,3). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-3=\dfrac{3-3}{5-(-1)}(x-(-1))[/tex]
[tex]y-3=\dfrac{0}{5+1}(x+1)[/tex]
[tex]y-3=0[/tex]
Adding 3 on both sides, we get
[tex]y-3+3=0+3[/tex]
[tex]y=3[/tex]
Therefore, the equation of the line is [tex]y=3[/tex].

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.

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].
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!

The perimeter of a rectangle a picture frame is 66 inches. the length is 3 inches greater than the width the system of linear equations used to represent the situation shown below.
2X + 2Y = 66 and X +3 =Y
solve the system name dimension represented by each variable
Given:
The perimeter of a rectangular picture frame is 66 inches [2X + 2Y = 66.]The length of the frame is 3 inches greater than the width [X + 3 = Y.]To find: The dimensions.
Answer:
Formula to find the perimeter of a rectangle = 2 × (Length + Width)
We know that 2X + 2Y = 66. Simplifying it, we get:
2(X + Y) = 66
X + Y = 66/2
X + Y = 33
Now that we know the value of X + Y, and assuming X and Y to be the dimensions, let's substitute it into the formula to find the perimeter and verify it.
Perimeter = 2 × (X + Y)
66 = 2 × 33
It's verified.
Now, we also have the expression representing the length, which is X + 3 = Y.
X + Y = 33
X + 3 = Y
Let's add both expressions.
X + Y + X + 3 = 33 + Y
2X + Y + 3 = 33 + Y
2X = 33 - 3 + Y - Y
2X = 30
X = 30/2
X = 15
Hence, the width [X] is 15.
Substituting this value into the expression representing the length,
15 + 3 = Y
18 = Y
Hence, the length and breadth of the rectangular picture frame is 18 and 15 units respectively.
Hope it helps. :)

Y=|____|x+|____|
Answer:
[tex]y=\frac{3}{4} x-2[/tex]
Step-by-step explanation:
The line has a positive slope, that much is clear. If we just count from the y-intercept up to the next clear point, we can see that it is 3 up and 4 to the right. That gives us a rise over run of 3 over 4, or [tex]\frac{3}{4}[/tex].
The y-intercept is -2, so that is the latter half of the equation.
