While this ratio changes over time, 1 Euro is currently valued at 1.21 U.S. Dollars. Use proportions to find the cost in U.S. Dollars of an item costing 48.14 Euros. Then, find the cost in Euros of an item that costs 97.72 US Dollars. Fill in the four blanks below.
Proportion equation used for answer below:_________
48.14 Euros=__________ US Dollars
Proportion equation used for answer below:__________
97.72 US Dollars = _________ Euros
Answer:
48.14= $58.25
$97.92= 81.27 euro
Step-by-step explanation:
Giving the following information:
1 Euro is currently valued at 1.21 U.S. Dollars.
First, we need to calculate the dollar value of 48.14 euros.
Proportion equation used for answer below: 1e= 1.21d
48.14*1.21= $58.25
Now, the euro value of 97.72 dollars.
Proportion equation used for answer below: (1:1.21) 0.83
1 dollar equals 0.83 euro.
97.92*0.83= 81.27 euro

What are the coordinates of the image if this pre-image is reflected over the y axis?
Answer:
A (2, 4)
B (-6, 4)
C (-6, 2)
D (2, 2)
Step-by-step explanation:
If it is being reflecting across the y-axis, the rule is this:
(x, y) ---> (-x, y)
So...
A (-2, 4) ---> (2, 4)
B (6, 4) ---> (-6, 4)
C (6, 2) ---> (-6, 2)
D (-2, 2) ---> (2, 2)

The function d = 16t2 models the distance d, in feet, that an object falls in t seconds. Find the inverse function and use the inverse function
o estimate the time it takes an object to fall 100 feet. (1 point)
Answer:
[tex]t = \frac{1}{4}\sqrt d[/tex]
Time to reach 100ft is 2.5 seconds
Step-by-step explanation:
Given
[tex]d = 16t^2[/tex]
Solving (a): Determine the inverse function
[tex]d = 16t^2[/tex]
Swap the positions of d and t
[tex]t = 16d^2[/tex]
Make d the subject
[tex]\frac{t}{16} = d^2[/tex]
Take positive square root of both sides
[tex]\sqrt{\frac{t}{16}} = d[/tex]
[tex]d = \sqrt{\frac{t}{16}}[/tex]
[tex]d = \frac{1}{4}\sqrt t[/tex]
Swap the positions of d and t
[tex]t = \frac{1}{4}\sqrt d[/tex] --- The inverse function
Solving (b): Find t when d =100
Substitute 100 for d in [tex]t = \frac{1}{4}\sqrt d[/tex]
[tex]t = \frac{1}{4}\sqrt {100[/tex]
[tex]t = \frac{1}{4}* 10[/tex]
[tex]t = \frac{1* 10}{4}[/tex]
[tex]t = \frac{10}{4}[/tex]
[tex]t = 2.5[/tex]

( 4, -12)
Step-by-step explanation:
m= y2- y1/ x2-x1
m= 12 - 4/ 4 - 2
m= 8/ 2
m= 4
y= 4x + b
(2,4)
4= 4(4) + b

Make P the subject of the formula
pliz pliz ans this
A= P(1+(r/100))^t
Answer:
P = A / (1 + r/100)ᵗ
Step-by-step explanation:
A = P(1 + r/100)ᵗ
We can make P the subject of the above expression as follow:
A = P(1 + r/100)ᵗ
Divide both side by (1 + r/100)ᵗ
P = A / (1 + r/100)ᵗ
Therefore, making P the subject of
A = P(1 + r/100)ᵗ, we have
P = A / (1 + r/100)ᵗ

Answer:
(d) x = 3
Step-by-step explanation:
The "vertex form" of the equation of a parabola is ...
y = a(x -h)² +k
In this form, the vertex has coordinates (h, k).
Comparing the form to your equation, you see that h=3, k=4, so the vertex is (h, k) = (3, 4).
The line of symmetry is a vertical line through the vertex. It will have the same x-value as the x-coordinate of the vertex:
x = 3
_____
In short, the equation of the line of symmetry has its constant equal to the opposite of the value added to x. Here, the added constant is -3, so the line of symmetry is x=3.
The values h and k in the vertex-form equation represent the amount of translation right and up from the parent function graph. When the graph is translated 3 units to the right, the line of symmetry moves from x=0 to x=3.

A hula hoop has an circumference 150.72 cm. What is the area of the hula hoop? (round to the nearest hundredth)
Answer:
Area = 1808.64 cm
Step-by-step explanation:
Circumference of a circle = 2πr
Circumference = 150.72
π = 3.14
r = radius
150.72 = 2 x 3.14 x r
150.72 = 6.28 r
r = 150.72/6.28
r = 24cm
Radius = 24
Area of a circle = πr²
Area = 3.14 x 24²
Area = 3.14 x 576
Area =1808.64 cm
Answer:
1808.64 cm

1/3 of Cheryl’s savings was the same as 3/4 of Hilda’s savings.Cheryl saved $36.
(a) Find the ratio of Cheryl’s savings to Hilda’s savings.
(b) How much did Hilda save?
Answer:
a) the ratio is 9:4
b) Hilda did save $16.
Step-by-step explanation:
Let's define the variables:
C = Cheryl's savings.
H = Hilda's savings.
We know that:
(1/3)*C = (3/4)*H
We also know that Cheryl saved $36, then we have:
C = $36
Now we can replace that in the above equation to get:
(1/3)*$36 = (3/4)*H
$12 = (3/4)*H
$12*(4/3) = H = $16
Then Hilda did save $16.
And the ratio between of Cheryl's savings to Hilda's savings is:
36 : 16
We can simplify this if we divide both by 2.
(36/2) : 16/2
18 : 8
Again, we can divide both by 2:
(18/2) : (8/2)
9 : 4
Then the ratio is 9 : 4
