Answer:

(a) Increased by 100%

(b) Increased by 50%

(c) Decreased by 33.33%

(d) Decreased by 50%

(e) Increased by 200%

(f) Decreased by 66.67%

Step-by-step explanation:

In this question, we can use the following <em>formula</em>:

$\text{Percentage Change =} \dfrac{\text{New value - Old Value}}{\text{Old Value}} \times 100$

Positive value of percentage change means increase and

Negative value of percentage change means decrease.

Solution a)

Old Value = 1

New Value = 2

$\text{Percentage Change =} \dfrac{\text{2 - 1}}{\text{1}} \times 100\\\Rightarrow 100\%$

Increase of 100%

Solution b)

Old Value = 2

New Value = 3

$\text{Percentage Change =} \dfrac{\text{3 - 2}}{\text{2}} \times 100\\\Rightarrow 50\%$

Increase of 50%.

Solution c)

Old Value = 3

New Value = 2

$\text{Percentage Change =} \dfrac{\text{2 - 3}}{\text{3}} \times 100\\\Rightarrow -33.33\%$

Decrease of 33.33%.

Solution d)

Old Value = 2

New Value = 1

$\text{Percentage Change =} \dfrac{\text{1 - 2}}{\text{2}} \times 100\\\Rightarrow -50\%$

Decrease of 50%.

Solution e)

Old Value = 1

New Value = 3

$\text{Percentage Change =} \dfrac{\text{3 - 1}}{\text{1}} \times 100\\\Rightarrow 200\%$

Increase of 200%.

Solution f)

Old Value = 3

New Value = 1

$\text{Percentage Change =} \dfrac{\text{1 - 3}}{\text{3}} \times 100\\\Rightarrow -66.67\%$

Decrease of 66.67%.

So, the answer is:

(a) Increased by 100%

(b) Increased by 50%

(c) Decreased by 33.33%

(d) Decreased by 50%

(e) Increased by 200%

(f) Decreased by 66.67%

Jeff and his family are driving to visit his grandmother they have driven about 30 miles which is about 2/3 of the way how much

Scilla [17]

Answer: 15 miles

<u>Step-by-step explanation:</u>

2/3 of the way is 30 miles

Let x represent the total distance to grandmother's house, then

$\quad \dfrac{2}{3}x=30\\\\\rightarrow 2x=90\\\\\rightarrow x = 45$

Since the total distance is 45 and they have already driven 30 miles, there is 15 miles to go

Hey! can someone please give me ideas on what type of art i could make, thanks im so confused

pogonyaev

Alright, so uno.

By six types of triangles, I'll assume that your teacher meant acute, right, obtuse, scalene, isosceles, and equilateral.

Some easy things to make with triangles are flags.

You could make a triangular leaf, with triangles as the stem.

Look up animals made out tangram triangles for some inspiration.

Honestly, just do whatever you wanna do.
