Let the number be multiplied be 'x'.
Therefore, according to the given conditions:
[tex] \rm\longmapsto {3}^{ - 3} \times x = 4[/tex]
We know that:
[tex] \rm\red⇛ {x}^{ - a} = \dfrac{1}{ {x}^{a} } [/tex]
Therefore:
[tex] \rm\longmapsto \dfrac{1}{ {3}^{3} } \times x = 4[/tex]
[tex] \rm\longmapsto \dfrac{x}{27 } = 4[/tex]
Multiplying both sides by 27, we get:
[tex] \rm\longmapsto27 \times \dfrac{x}{27 } = 4 \times 27[/tex]
[tex] \rm\longmapsto x = 4 \times 27[/tex]
[tex] \rm\longmapsto x = 108[/tex]
So, 108 must be multiplied to get 4.
Verification:
Substitute x = 108, we get:
[tex] \rm = {3}^{ - 3} \times 108 [/tex]
[tex] \rm = \dfrac{1}{27} \times 108 [/tex]
[tex] \rm = \dfrac{1}{27} \times 27 \times 4[/tex]
[tex] \rm =4[/tex]

A music store originally purchased a piano at a cost of $892.03 and marked it up 125%. After a few weeks, however, the store discounted the piano 50% in order to make room for new merchandise. What was the discounted price?
Answer:
$557.52
Step-by-step explanation:
1. Find the marked up price.
125% = 1.25
$892.03 x 1.25 = $1,115.04
2. Find the discounted price.
50% = 0.5
$1,115.04 x 0.5 = $557.52

The length of a square table is 1.25m. An ant walks around the edge of the table.How far does the ant walk?
Answer:
5m
Step-by-step explanation:
1.25m multiply by 4 sides equals 5m
The length of which ant walk will be the same as the perimeter of the square thus it will be 5 meters.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
Perimeter of square = side + side + side + side
Given a table in form of a square,
Side of square = 1.25 m
The external measure of side = length of ant walk
1.25 + 1.25 + 1.25 +1.25 = Length of ant walkt
Length of ant walk = 5 meters.
Hence "The length of which ant walk will be the same as the perimeter of the square thus it will be 5 meters".

Someone please answer this?
Answer:
y = 2x + 5
Step-by-step explanation:
First, you must choose two ordered pairs from the table to solve for the slope (m):
Let (x1, y1) = (0, 5)
(x2, y2) = (1, 7)
Substitute the given values into the following slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{7 - 5}{1 - 0} = \frac{2}{1} = 2[/tex]
Therefore, the slope (m) = 2.
The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b ). It is also the value of y when x = 0. Looking at the given table, (0, 5) reflects the description of the y-intercept. The y-intercept (b) is the y-coordinate of (0, 5).
Given the slope (m) = 2, and y-intercept (b) = 5, the linear equation is:
y = 2x + 5

Write an equation in slope intercept form for the line perpendicular to y = 2x - 3 that passes through the point (-3, -3)
Answer:
y=-1/2x-9/2
Step-by-step explanation:
check picture
The equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.
To find the equation of a line perpendicular to y = 2x - 3, we need to determine the slope of the original line and then find the negative reciprocal of that slope.
The original line has a slope of 2. The negative reciprocal of 2 is -1/2.
Now, we have the slope (-1/2) and the point (-3, -3) that the perpendicular line passes through.
We can use the point-slope form of a linear equation to write the equation of the line:
y - y1 = m(x - x1)
Substituting the values:
y - (-3) = (-1/2)(x - (-3))
y + 3 = (-1/2)(x + 3)
Expanding and simplifying:
y + 3 = (-1/2)x - 3/2
y = (-1/2)x - 3/2 - 3
y = (-1/2)x - 3/2 - 6/2
y = (-1/2)x - 9/2
Therefore, the equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

triangle xyz is similar to abc,enter the missing side length.
First, find the scale factor:
8/4.6 ≈ 1.73913043478
12/1.73913043478 = 6.9
6.9If triangle XYZ is similar to ABC then the length of the missing side is 6.90. It is obtained by using the scale factor concept.
What is the triangle?In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is given that ΔXYZ ≅ ΔABC.
Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
When two triangles are similar their scale factor is the same for each side,
The scale factor is obtained by taking the ratio of their sides,
= AC / XZ
= 8 / 4.6
= 1.739
The length of side XY is found as,
Scale factor = AB / XY
1.739 = 12 / XY
XY = 6.90
Thus, if triangle XYZ is similar to ABC then the length of the missing side is 6.90. It is obtained by using the scale factor concept.

Joseph owes his mother $12.25. He borrows $6.50 more from his mother. Which of the following best represents Joseph's debt to his mother?
Answer:
18.75.
Step-by-step explanation:
If he already owes his mother 12.25 and borrows 6.50, we can add those numbers up to get the total amount of how much he owes his mother.
12.25 + 6.50 = 18.75
Therefore, Joseph's debt to his mother can be represented using the equation above.

4 over 10
2 over 8
3 over 5
4 over 12
6 over 10
3 over 6
Answer: 4/10 = 2/5
2/8 = 1/4
3/5 = 3/5
4/12 = 1/3
6/10 = 3/5
3/6 = 1/2
Step-by-step explanation:
4/10 = 2/5
4/10 is not in its simplest form.
Both 4 and 10 can be divided by 2.
Therefore, 4/10 = 2/5
2/8 = 1/4
2/8 is not in its simplest form
2 / 2 = 1
8 / 2 = 4
Both 2 and 8 can be divided by 2, therefore, 2/8 = 1/4
3/5 = 3/5
3/5 is in its simplest form
3 and 5 are prime, so they don’t have any factors other than 1 and itself so they wouldn’t be able to be simplified.
4/12 = 1/3
4/12 is not in its simplest form
4 / 4 = 1
12 / 4 = 3
4 and 12 can be divided by 4, resulting in 1 and 3. Therefore, 4/12 = 1/3.
6/10 = 3/5
6/10 is not in its simplest form
6 / 2 = 3
10 / 2 = 5
6 and 10 can both be divided by 2, resulting in 3/5. Therefore, 6/10 = 3/5
3/6 = 1/2
3/6 is not in its simplest form
3 / 3 = 1
6 / 3 = 2
Both 3 and 6 can be divided by 3, resulting in 1/2
Therefore, 3/6 = 1/2
Short Answers:
4/10 = 2/5
2/8 = 1/4
3/5 = 3/5
4/12 = 1/3
6/10 = 3/5
3/6 = 1/2

Light bulbs cost £3.40 each.
Yasmin buys as many as she can with £30.
How much change should she get?
Give your answer in pounds, £.
======================================================
Work Shown:
x = number of light bulbs
3.40x = total cost to buy x light bulbs, cost is in pounds
3.40x = 30
x = 30/(3.40)
x = 8.823529 approximately
Rounding down, we get 8
Note that,
3.40*8 = 27.20 pounds which is under budget3.40*9 = 30.60 pounds which is over budgetTherefore, the highest number of bulbs that can be bought is 8.
The change given will be 30-27.20 = 2.80 pounds
