Circle V and Circle W are similar and the radius of Circle V is 16; however, Circle V and Circle W do not have the same center, and the center of Circle V is not (-5, 0), but rather (-3, -2).
Given the information that Circle W has center (-3, 0) and radius 8, and Circle V is a translation of Circle W 2 units down and a dilation with a scale factor of 2, the following statements can be evaluated:
Circle V and Circle W are similar: This statement is true. Both circles maintain their shape after a translation and dilation.Circle V and Circle W have the same center: This statement is false. Translation moves the center of Circle V 2 units down, changing its coordinates.The radius of Circle V is 16: This statement is true. The radius is doubled through the dilation process.The center of Circle V is (-5, 0): This statement is false. The correct center after translation would be (-3, -2).20 PTS! Need help!

Answer:
m∠x = 63°
m∠y =45°
m∠z = 72°
I hope this helps! :)
Answer:
Step-by-step explanation:
It is given that ABCD is a parallelogram, thus by using the properties of parallelogram, we have
∠A=∠C (Opposite angles of parallelogram are equal)
⇒∠x=63°
Thus, the measure of angle A that is x is 63°.
Now, ∠ABC+∠BCD=180°(Corresponding angles of parallelogram)
⇒∠ABD+∠DBC+63=180
⇒∠DBC=180-135
⇒∠DBC=45°
Thus, y=∠DBC=45° (Alternate angles)
and z=∠DBA=72° (Alternate angles)
Hence, the measure of angle x, y and z are 63°, 45° and 72° respectively.

The perimeter of a rectangle is 42 centimeters.What is the length and width if the width is 3 centimeters more than half the length? Please include work.
The rectangle's length is 12 cm, and the width is 9 cm, calculated by setting up a system of equations using the given perimeter and the relationship between length and width.
Explanation:To find the length and width of the rectangle when given its perimeter and a relationship between its length and width, we can set up a system of equations. First, let's denote the length of the rectangle as L and the width as W. According to the question, the width is 3 centimeters more than half the length, so we have W = ½L + 3.
Since the perimeter (P) of a rectangle is given by P = 2L + 2W, and we know the perimeter is 42 centimeters, we can set up an equation: 42 = 2L + 2(½L + 3). Simplifying this, we get 42 = 2L + L + 6 or 42 = 3L + 6. Subtracting 6 from both sides gives us 36 = 3L or L = 12 centimeters for the length.
Now we can find the width using the previous relationship W = ½L + 3. Substituting the value of L, we get W = ½(12) + 3 = 6 + 3 = 9 centimeters for the width.
Therefore, the length is 12 centimeters and the width is 9 centimeters.

Anita divides 1438 by a multiple of 10. Her answer has a 3 in the tenths column. what number did she divide by?
Answer:
40
Step-by-step explanation:
Given that Anita divides 1438 by a multiple of 10
i.e. she might have divided by 10 or 20 or 30 .....
The tenth column is 3
So quotient value would be
30+d for some d in the unit column
It may be 31 or 32.....
Say it is 31, then 1438/31 =46.38 and
1438/39 = 36.87
i.e she must have divided by 40 only
Verify:
1438/40 =35 as quotient and 38 as remainder.
So she divided by 40

Martin says the area of a tile with a length of 1 foot by a width of 1 foot has an area of 1 square foot. And, to find 1 2 12 of this area, he would need to find 1 2 12 of the width and 1 2 12 of the length, and then multiply those two values. Unfortunately, his method is incorrect. Show at least one equation to show why this method would not work, and briefly state a method that will find 1 2 12 of 1 square foot.
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
If two figures are similar. then the ratio of its areas is equal to the scale factor squared
In this problem we have a tile with a length of 1 foot by a width of 1 foot
The area of the tile is equal to
[tex]A=LW[/tex]
substitute the values
[tex]A=(1)(1)=1\ ft^{2}[/tex]
Let
z-------> the scale factor
x------> the area of 1/2 tile
y------> the area of the original tile
so
[tex]z^{2} =\frac{x}{y}[/tex]
substitute
[tex]z^{2} =\frac{(1/2)}{1}[/tex]
[tex]z=\frac{\sqrt{2}}{2}[/tex] -----> scale factor
therefore
To find the area of 1/2 tile must multiply the dimensions of the tile by the scale factor
so
[tex]L=1*\frac{\sqrt{2}}{2}=\frac{\sqrt{2}}{2}\ in[/tex]
[tex]W=1*\frac{\sqrt{2}}{2}=\frac{\sqrt{2}}{2}\ in[/tex]
Calculate the area
[tex]A=\frac{\sqrt{2}}{2}*\frac{\sqrt{2}}{2}=\frac{1}{2}\ ft^{2}[/tex]
Martin's method is incorrect because to find the area of 1/2 tile, he multiplies the dimensions by 1/2
so
[tex]L=1*\frac{1}{2}=\frac{1}{2}\ in[/tex]
[tex]W=1*\frac{1}{2}=\frac{1}{2}\ in[/tex]
the area will be
[tex]A=\frac{1}{2}*\frac{1}{2}=\frac{1}{4}\ ft^{2}[/tex]

[tex]\frac{32}{100}[/tex] × 400
0.32 × 400 = 128
128 Shoppers prefer bananas.
Martin says the area of a tile with a length of 1 foot by a width of 1 foot has an area of 1 square foot. And, to find 1/2 of this area, he would need to find 1/2 of the width and 1/2 of the length, and then multiply those two values. Unfortunately, his method is incorrect. Show at least one equation to show why this method would not work, and briefly state a method that will find 1/2 of 1 square foot.
Answer:
His method is incorrect. By finding 1/2 the width and 1/2 the length, if we multiply them , we would get 1/4 of the original area.
Area = 0.5*l*0.5*w = 0.25*l*w = l*w/4
Let us establish
length = l
width = w
Original Area = l*w
Half the area = (a*l)*(b*w) = 0.5*(l*w)
This means that
a*b = 0.5
if b is equal to a, then
a = √0.5 = √2/2 = 0.707
Then, if a factor of a, where to be introduced in the lenght and width of the tile, we would obtain half the area.

You have $3,750 to deposit. If you deposit the money in a savings account at your local bank, you will earn 1.75% annual interest and will be able to make ATM withdrawals at your bank’s ATMs. If you deposit the money in an online savings account, you will earn 3.25% interest, but you will be charged $4 every time you make an ATM withdrawal. Assuming that your ATM withdrawals do not reduce the amount of interest you earn, roughly how often must you make an ATM withdrawal for the local savings account to be a better deal than the online savings account?
To determine how often ATM withdrawals must be made for the local savings account to be a better deal than the online savings account, we compare the interest earned and ATM fees. By solving the inequality, it is found that more than $14.06 ATM withdrawals must be made in a year.
Explanation:To determine how often you must make ATM withdrawals for the local savings account to be a better deal than the online savings account, we need to compare the interest earned from each account and the fees associated with ATM withdrawals. Let's assume the time period is one year.
For the local savings account, you earn interest of 1.75% annually. So, if you deposit $3,750, you will earn ($3,750 * 1.75%) = $65.63 in interest.
For the online savings account, you earn interest of 3.25% annually. However, each ATM withdrawal incurs a fee of $4. Let's assume you make 'x' withdrawals in a year. So, the total interest earned would be ($3,750 * 3.25%) - ($4 * x).
We need to find the point where the interest earned from the online savings account is less than the interest earned from the local savings account. This can be calculated as:
($3,750 * 3.25%) - ($4 * x) < $65.63
Simplifying this inequality, we get:
0.0325 * $3,750 - $4 * x < $65.63
Adding $4 * x to both sides, we have:
0.0325 * $3,750 < $65.63 + $4 * x
Simplifying further, we get:
$121.87 < $65.63 + $4 * x
Subtracting $65.63 from both sides, we have:
$121.87 - $65.63 < $4 * x
Simplifying again, we get:
$56.24 < $4 * x
Dividing both sides by $4, we find:
$14.06 < x
So, you must make more than $14.06 ATM withdrawals in a year for the local savings account to be a better deal than the online savings account.
