Dawn has 2 quarters, 1 nickel, and one $1 bill. How much money does Dawn have?

2 answers:

Dawn has 1.55 because 2 quarters equal 50 cent then a nickel is equal to 5 cents plus the dollar so 50+5=55 plus the dollar which is equal to 1.55

What is the value of x?<br> 12 units<br> 15 units<br> 20 units<br> 25 units

Firlakuza [10]

Answer:

The answer is 12 units.

Step-by-step explanation:

Looking at the figure we see that

$(1).9^2+x^2=SR^2$

$(2).16^2+x^2=RQ^2$ and

$(3).SR^2+RQ^2=(9+16)^2$

Now from equations (1) and (2) we have values for $SR^2$ and $RQ^2,$ so we put those into the equation (3) and get:

$9^2+x^2+16^2+x^2=(9+16)^2$

$\rightarrow 337+2x^2=625$

$\boxed{\therefore x= 12.}$

Therefore the answer is 12 units.

In the triangles shown, ABC is dilated by a scale factor of to form XYZ. Given that mA = 45o and mB = 105o, what is mZ?

kompoz [17]

The value of angle Z is 30 degrees

<h3>How to determine the value of angle Z?</h3>

The given parameters are:

ABC is dilated to form XYZ

This means that the triangles ABC and XYZ are similar triangles and the corresponding angles are equal

So, we have the following angle equations

A = X

B = Y

C = Z

Also, we have

A + B + C = 180

Substitute C = Z in A + B + C = 180

A + B + Z = 180

Substitute A = 45 and B = 105

So, we have:

45 + 105 + Z = 180

Evaluate the like terms

150 + Z = 180

Subtract 150 from both sides

Z = 30

Hence, the value of angle Z is 30 degrees
