Answer:

Percent Increase in measure of the side of a square = 30%

Step-by-step explanation:

Let the measure of the side of a square = s

Area of the square = (Side)²

                                = s²

If the area of the square is increased by 69%

Area of the new square = s² + 69% of s²

                                        = s² + 0.69s²

                                        = 1.69s²

Therefore, measure of the side of the new square = √(Area of the square)

                                                                                    = √(1.69s²)

                                                                                    = 1.3s

Measure of side of the old square = s

Therefore, increase in measure of the square = 1.3s - s

                                                                            = 0.3s

Percent increase in the measure of the side of the square

= [tex]\frac{\text{Increase in measure}}{\text{Measure of the side of the original square}}\times 100[/tex]

= [tex]\frac{0.3s}{s}\times 100[/tex]

= 30%

Answer:

y = 5

z = 55

Step-by-step explanation:

90 - 35 = 55

z = 55

7y = 35

[tex]\frac{7y}{7} = \frac{35}{7}[/tex]

y= 5

Answer:

  not similar

Step-by-step explanation:

For the triangles to be similar, at least two angles must match. Here, there is an 81° angle in both triangles. This means the sum of the remaining two angles must be ...

  180° -81° = 99°

If the missing angle in either triangle matched the other given angle in the opposite triangle, the sum of those would be 60° + 40° = 100°, not 99°. This triangle pair does not have two matching angles, so the triangles are not similar.

ABC angles: 60°, 81°, 39°

FED angles: 59°, 81°, 40°

Answer:

12.5m

Step-by-step explanation:

The missing length is the hypothenuse, the formula to calculate the hypothenuse is

[tex]c = \sqrt{a {}^{2} + b {}^{2} } [/tex]

[tex]c = \sqrt{10 {}^{2} + 7.5 {}^{2} } \\ c = \sqrt{100 + 56.25} \\ c = \sqrt{156.25} \\ c = 12.5[/tex]

Step-by-step explanation:

Answer:

ok let me try this again

To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.

did that help i was not a faker though i was just trying to explain it to him/she better and can i have brainlist please

Step-by-step explanation:

[tex]3n^3-5n+n^2+8n^2-3n^3\\ \\ 9n^2-5n\\ \\ or\ n(9n-5)[/tex]

Answer:

[tex]9n^2 - 5n[/tex]

Step-by-step explanation:

[tex](3n^3 - 5n + n^2) - (-8n^2 + 3n^3)[/tex]

Lets open the brackets. Signs of all the terms in the bracket next to the minus sign will change.

[tex]=> 3n^3 - 5n + n^2 + 8n^2 - 3n^3[/tex]

Now lets add/substract all the like terms with each other.

[tex]=> 3n^3 - 3n^3 + n^2 + 8n^2 - 5n[/tex]

[tex]=> 9n^2 - 5n \: \: or \:\: n(9n - 5)[/tex]

Question:

Which coordinate points match the statement below? Select all that apply.

Every y-value is 4 times greater than the x-value

(4,20)      (2,10)        (8,12)       (7,35)

Answer:

(4,20)      (2,10)    (7,35)

Step-by-step explanation:

Given

y-value = 4 times greater than x-value

Required

Determine the right coordinate points

y is 4 times greater x implies that:

[tex]y = x + 4 * x[/tex]

[tex]y = x + 4x[/tex]

[tex]y = 5x[/tex]

Checking the given coordinates one after the other.

[tex](x,y) = (4,20)[/tex]

[tex]20=5 * 4[/tex]

[tex]20= 20[/tex] --- True

[tex](x,y) = (2,10)[/tex]

[tex]10= 5 * 2[/tex]

[tex]10 = 10[/tex]

[tex](x,y) = (8,12)[/tex]

[tex]12 = 5 *8[/tex]

[tex]12 = 40[/tex] --- False

[tex](x,y) = (7,35)[/tex]

[tex]35 = 5*7[/tex]

[tex]35 = 35[/tex] --- True

Hence, the coordinate points that match are:

(4,20)      (2,10)    (7,35)
