Answer:

angle four equals angle 7 because they are alternate angles in a way.

Step-by-step explanation:

First if you go diagonally up from angle 4, you get angle 5. Then you go diagonally down. That angle isn't marked so I'll call it Z. But you could do it a faster way. You see, you could replace angle 4 with angle Z and vice versa. Then angle Z is the alternate angle of angle 7. One rule you should remember:

Alternate angles are equal.

Does this help? If it doesn't make sense let me know. (When I was learning this, it didn't make sense either)

An anthropologist studies a woman's femur that was uncovered in Madagascar. To estimate the woman's height, he uses the equation

Lelu [443]

Answer:

The inequality $f>40$ represents the length of the femur for which the woman had a height greater than 160cm.

Step-by-step explanation:

The given equation is

$h=60+2.5f$

Where, h is woman's height in centimeters and f is length of the femur in centimeters.

If woman's height is greater than 160cm, then

$h>160$

$60+2.5f>160$

Substract 60 from both sides.

$2.5f>100$

Divide both sides by 2.5.

$f>40$

Therefore the inequality $f>40$ represents the lengths of the femur for which the woman had a height greater than 160cm.

Explain how the distance formula can prove Pythagoras' Theorem. In your

Paul [167]

Answer:

Given a triangle ABC, Pythagoras' Theorem shows that:

$c^2=a^2+b^2$

Thus,

$c = \sqrt{a^2+b^2}$

The distance formula, gives an equivalent expression based on two points at the end of the hypotenuse for a triangle.

$d^2 = (x_{2} -x_{1})^2 + (y_{2} -y_{1})^2$

$d = \sqrt{(x_{2}-x_{1})^2 + (y_{2} -y_{1})^2 }$

Therefore when given the hypotenuse with endpoints at

$(x_{1}, y_{1}) and {(x_{2}, y_{2})$

We know that the third point of the right triangle will be at

$(x_{2}, y_{1})$

and that the two side lengths will be defined by the absolute values of:

$(x_{2} - x_{1}) = a$

$(y_{2} - y_{1}) = b$

Your hotdogs currently have a menu price of $2.80 + $.10 for extra sauerkraut. You want to include the sauerkraut in the cost an

jasenka [17]

Answer:

C) $3.77

Step-by-step explanation:

$2.80 + $0.10 = $2.90

Turn 30% into 0.30 by moving the decimal point (percentage sign) 2 places to the left.

To solve 30% of $2.90 → 0.30 x 2.90 = 0.87

Finally $2.90 + $0.87 = $3.77
