A golf driving range charges a flat fee of $20 to practice and then $5.75 for a buckets of balls. Write an equation that models the charges (C) in terms of the number of bucket of balls (b) that you use
Answer:
A
Step-by-step explanation:
Flat fee is $20 [initial cost]
Each bucket of ball is $5.75
b is the number of buckets and c is the total cost
To get total cost, we add the flat fee with the bucket fee. Bucket fee is $5.75 multiplied by the number of buckets, which is b.
So, we have:
cost = $20 + $5.75b

Eva buys a piece of red fabric that is 5.6 meters long and a piece of yellow fabric that is 2.8 meters long. How long are the two pieces of fabric together in millimeters?
Answer:
Total length of fabric pieces is 8400 mm.
Step-by-step explanation:
Eva buys a piece of red fabric of length = 5.6 meters
Since, 1 meter = 1000 mm
Therefor, 5.6 meter = 5.6 × 1000
= 5600 mm
Similarly, length of yellow fabric piece = 2.8 meters
≈ 2.8 × 1000 mm
≈ 2800 mm
If these pieces are joined together, total length of the fabric pieces
= 5600 + 2800
= 8400 mm
Therefore, total length of fabric pieces is 8400 mm.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Vertie rode 3.5 kilometers on a bike. His friend Valene rode 2 000
meters on a bike.
We know that
one kilometer = 1000 meters
or
1 meter = 1/1000 km
2000 meter will be equal to
2000/1000 = 2 km
So, the difference between the ride of the friends would be
3.5 km - 2 km
= 1.5 km

y = 5x^2 - 10
what is the rate of change ?
is the function linear or non linear ? why ?
Answer:
Step-by-step explanation:
Are you in Calculus? These are calculus concepts!
To calculate the rate of change here you must specify an interval, e. g., "what is the rate of change on the interval (0, 3)?"
If you know calculus: The 'rate of change' on the interval (a, b) is
f(b) - f(a)
r. of c. = --------------------
b - a
Have you used this formula before?
Because of the 'x^2' term this is NOT a linear function.
If you want more explanation, provide an interval on which you want the average rate of change and ask specific questions of your own.

We have the unit rate of 30 meters per second.
A) 90 meters in 5 seconds.
The unit rate = 90/5 meters per second.
The unit rate = 18 meters per second.
B) 90 meters in 3 seconds.
The unit rate = 30 meters per second.
C) 120 meters in 6 seconds.
The unit rate = 20 meters per second.
D) 150 meters in 5 seconds.
The unit rate = 30 meters per second.

A building in the shape of a cube has a width of 30 ft., a length of 30 ft., and a height of 30 ft. An architect wants to build a scale model of the building that is 10% smaller in volume. What is the height of the new building?
Answer:
Step-by-step explanation:
The height of the scale model is 13.92 feet. (Rounding to the nearest hundredth).
Step-by-step explanation:
These are the measurements of the real building:
Height = 30 feet
Width = 30 feet
Length = 30 feet
Volume of the real building = 30 * 30 * 30 = 27,000 cubic feet
These are the measurements of the scale model:
Volume of the scale model = 10% of 27,000 cubic feet
Volume of the scale model = 0.1 * 27,000 = 2,700 cubic feet
Height = ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
Width = ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
Length =∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
The height of the scale model is 13.92 feet.
Answer:
28,96 ft (round to the nearest hundreds)
Step-by-step explanation:
1) find the volume of the first cube
V = side^3 = 30^3 = 27000 ft^3
2) find the 10% of 27000
27000 / 0,1 = 2700
3) find the volume of the second cube
V = 27000- 2700 = 24300 ft^3
4) find the height
height = ∛24300 = 28,96 ft (round to the nearest hundreds)
