Brianna makes a model of the Eiffel Tower for a school project. Her model is 25 centimeters wide at the bottom
If Brianna used a scale of 1 centimeter for every 5 meters, how vide is the actual Efe Towet?
The actual Eiffel Tower is 125 meters wide .
What is Multiplication?
Along with addition, subtraction, and division, multiplication is one of the four basic arithmetic operations. In mathematics, multiplication is the repeated addition of groups of equal size.
Here given, Brianna makes a model of the Eiffel Tower for a school project.
It is also given that the model is 25 cm wide at the bottom and Brianna used a scale of 1 centimeter for every 5 meters.
By multiplication, we can find the actual length of Eiffel tower
Here 1 centimeter for every 5 meters.
So, 25 centimeter means (5×25) = 125 meters.
Therefore, the actual length of the Eiffel tower is 125 meters.

A field hockey field is rectangular. Its width is 54.88 meters, and its perimeter is 289.76 meters. Find the length of the field.
Answer:
90 PLEASE MARK ME BRAINLLIEST
Step-by-step explanation:
289.76-54.88-54.88=180/2=90
Perimeter is the sum of the length of the sides used to make the given figure. The length of the field is 90 meters.
What is the perimeter?Perimeter is the sum of the length of the sides used to make the given figure.
Given that the width of the field is 54.88 meters and the perimeter of the field is 289.76 meters. Therefore, we can write the perimeter as,
Perimeter = 2(Length + Width)
289.76 meters = 2(Length + 54.88 meters)
289.76meters / 2 = Length + 54.88 meters
144.88metes = Length + 54.88 meters
Length = 144.88 meters - 54.88 meters
Length = 90 meters
Hence, the length of the field is 90 meters.

Step-by-step explanation:
Which is one of the transformations applied to the graph of f(x)=x2 to change it into the graph of g(x) = -x2 + 16x – 44?
The graph of f(x) = x2 is widened.
The graph of f(x) = x2 is shifted left 8 units. O
The graph of f(x) = x2 is shifted down 44 units.
The graph of f(x) = x2 is reflected over the x-axis.
Answer:
Only option D is one of the transformations needed.
Step-by-step explanation:
The graph of f(x)=x^2 is a positive parabola with x=0 as the zero in ordinates and also 0 as a zero x. This is, the graph passes in (0,0) and this is the only point it crosses both axis, then for every x value we will gave a positive f(x).
Here I attach a graph that shows both, f(x)=x^2 and g(x)=-x^2+16x-44.
As you can see, for transforming f(x) in g(x) we need to reflect it over the x axis, as g is open downwards. Then, as the quadratic term is still being x^2 we do not wide it (as you see in the graph both curves are equally widened).
Then, we can also see that the graph is shifted right, so we do not shift it left 8 units (notice that we shift it right 8 units).
So, after reflecting over the x axis and shifting right we need to shift it UP, as we can see the graph is over the x axis.
So, the three transformations needed are:
1. reflect over the x axis
2. shift right 8 units
3. shift up 20 units.
So, from the options you proposed we chose only d, to which we MUST add the transformations noted above.
Sorry for the mistake!

A scooter travels 30 feet in 2 seconds at a constant speed.
The distance the scooter travels in 1 second is
feet. The distance the scooter travels in 3 seconds is
feet. The distance the scooter travels in 4 second is
feet. The distance the scooter travels in 5 second is
feet.
Answer:
The scooter travels 15 feet in 1 second
The scooter travels 45 feet in 3 seconds
The scooter travels 60 feet in 4 seconds
The scooter travels 75 feet in 5 seconds
Step-by-step explanation:
First, let's find the number of feet the scooter travels in 1 second
(30 : 2) ÷ 2 = 15 : 1
Now that we have the unit rate, we can easily find the answers to the other questions.
(15 : 1) x 3 = 45 : 3
(15 : 1) x 4 = 60 : 4
(15 : 1) x 5 = 75 : 5
