Answer:

<h2>64%</h2>

Step-by-step explanation:

\bold{METHOD\ 1:}\\\\\begin{array}{ccc}25g&-&100\%\\\\16g&-&p\%\end{array}\qquad\text{cross multiply}\\\\\\25p=(16)(100)\\25p=1600\qquad\text{divide both sides by 25}\\\boxed{p=64}

\bold{METHOD\ 2}:\\\\\begin{array}{cccc}25&-&100\%&\text{divide both sides by 25}\\\\\dfrac{25}{25}&-&\dfrac{100\%}{25}\\\\1&-&4\%&\text{multiply both sides by 16}\\\\(1)(16)&-&(4\%)(16)\\\\16&-&64\%\end{array}

How many different books did the children read
Alex777 [14]

Answer:

16 books

Step-by-step explanation:

if Sandra read 5 books and Deacon read 6 and Breanna read 7 and they all one same book, then that means sandra read 4 different books then Deacon and Breanna. Deacon read 5 different books then Sandra and Breanna. Breanna read 6 different books then Deacon and Sandra.

So Sandras 4 books plus Deacons 5 books plus Breannas 6 books equals up to 15 but, now you need to add the one book they all read which makes the answer 16.

Which equation represents a linear function?
Anna007 [38]

Answer:

y-2=-5(x - 2)

Step-by-step explanation:

Given:

The equations given are:

y-2=-5(x - 2)\\X+ 7 = -4(X + 8)\\y - 3 = y(x + 4)\\y + 9 = x(x - 1)

Now, a linear function is of the form:

y=mx+b

Where, 'm' and 'b' are real numbers and m\ne0

Equation 1: y-2=-5(x - 2)

Simplifying using distributive property, we get:

y-2=-5x+10\\y=-5x+10+2\\y=-5x+12

The above equation is of the form y=mx+b. So, it represents a linear function.

Equation 2: X+ 7 = -4(X + 8)

Here, both sides of the equation has same variable 'X'. So, it will form an equation of 1 variable. So, it's not a linear function.

Equation 3: y - 3 = y(x + 4)

Simplifying the above equation. This gives,

y-3=yx+4y\\y-4y-yx=3\\y(1-4-x)=3\\y(-3-x)=3\\y=\frac{3}{(-3-x)}

This is not of the form of the linear function. So, it is also not a linear function.

Equation 4: y + 9 = x(x - 1)

Simplifying the above equation. This gives,

y+9=x^2-x\\y=x^2-x-9

This is not of the form of the linear function. So, it is also not a linear function.

Please I need this answer I don’t understand
e-lub [12.9K]

Answer:

Step-by-step explanation:

by inspection

angles 2 and 3 are equal, so they will be half angle ABC

angles 1 and 5 are equal  so they will be

      angle 1 + angle 5 + angleABC = 180°      kind of a rule for triangle

                                                                        the sum of all angles - 180°

      (angle 1) x 2 = 180° - 70°

       angle 1 = 90° - 35°

      angle 1 = 55°   which equals angle 5

angle 4 is clearly a right angle 90°

DO the same procedure for the bottom triangle

angle 8 and 9 are half of angle ADC

angle 8 and 9 are half of 46°

both are 23°

angle 6 equals angle 7

2 ×angle 6 = 180° - 46°

angle 6 = 90° - 23°

angle 6 = 67°    angle 7 = 67°

Did I find them all
