kap26 [50]

Answer:

There was a increase of 1.7% over these three years

Step-by-step explanation:

Multipliers:

For a decrease of a%, we multiply by: $\frac{100-a}{100}$

For a increase of a%, we multiply by: $\frac{100+a}{100}$

What was the percentage increase/decrease of groundhogs over these three years?

Decrease of 12%(multiplication by 0.88).

Increase of 6%(multiplication by 1.06).

Increase of 9%(multiplication by 1.09).

After these three years:

0.88*1.06*1.09 = 1.017

1.017 - 1 = 0.017

0.017*100% = 1.7%

There was a increase of 1.7% over these three years

The question is incomplete. Here is the complete question:

Mr.yueng graded his students math quizzes students came up with four different answers when solving the equation x3=22. Which answers is correct.

(A) $\frac{22}{3}$

(B) $\sqrt[3]{22}$

(C) $\pm \sqrt[3]{22}$

(D) $\sqrt{22}$

Answer:

(B) $\sqrt[3]{22}$

Step-by-step explanation:

Given:

The equation to solve is given as:

$x^3=22$

Here, the left hand side of the equation has a variable 'x' in exponent form. So, in order to solve for 'x', we have to eliminate the exponent.

For removing the exponent, we have to take cubic root on both the sides. As we know that,

$\sqrt[n]{x^n} =x$

So, taking cubic root on both the sides, we get

$\sqrt[3]{x^3}=\sqrt[3]{22}\\\\x=\sqrt[3]{22}$

Therefore, the second student has written the correct answer and hence the correct option is (B).

I’m having a crisis so please help 7x-19<16

vampirchik [111]

Answer:

5 i believe correct me if im wrong

Step-by-step explanation:

To work this problem out you would do it as if it were just a simple equation

7x-19<16 (you would first have to add 19 to both sides)

7x<35 (then you would divide by 7 to get the variable by itself)

x<5 ( you answer would then be 5)
