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.

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

Answer:

Take the logarithm of both sides of the equation to remove the variable from the exponent.

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].

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].

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!

Given:

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. :)

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

Answer:

90

Step-by-step explanation:

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.
