5000/25=200
[tex]\dfrac{50}{0.25}\\\\\\=\dfrac{50}{\tfrac{25}{100}}\\\\\\=50 \times \dfrac{100}{25}\\\\\\=2 \times 100\\\\\\=200[/tex]
9) The diameter of a circular ice skating rink is 32 feet. What is the approximate area of the ice skating rink? Use a = 3.14. a) 803.84 square feet b) 50.24 square feet c) 100.48 square feet d) 64 square feet
Answer:
a) 803.84 square feet
Step-by-step explanation:
[tex]\sf{area~of~circle~=~\pi r^{2} }\\\sf{radius~ =~half~of~diameter}[/tex]
so 32 / 2 = 16 = radius
[tex]\sf{radius^{2} = 16^{2}=256}[/tex]
256 x 3.14 (because we are taking π as 3.14)
= 803.84

Step-by-step explanation:
a geometric sequence means that every term is created by multiplying the previous term by a certain constant factor. this factor is called the "common ratio".
so,
6×r = 18
r = 18/6 = 3
and a quick check tells us this works also for the next terms (18×3 = 54, 54×3 = 162), so it is indeed a geometric sequence with common ratio 3.
a0 = 6
a1 = a0 × 3 = 6×3 = 18
a2 = a1 × 3 = a0 × 3×3 = 6×3² = 54
an = a0 × 3^n = 6 × 3^n
so,
f(x) = 6×3^x, x is integer, x >=0
Find the volume of the sphere. Round your answer to the nearest tenth.
Use 3.14 for a.
A sphere has a radius of 3.5 feet.
The volume of the sphere is about
ft?
Answer:
179.50
Step-by-step explanation:
The formula for calculating pi is as followed: 4/3·π·r³
The question is either asking to calculate using 3.14 for π or add π at the end of your answer instead of completing it. I will substitute π for 3.14.
∴V=4/3·3.14·3.5³
V=179.503333333
Round your answer to the nearest hundredth:
179.503333333 rounded to the nearest hundredth becomes 179.50
∴V=179.50
-------------------------------------------------------------------------------------------------------------
Another way to answer this question is to use the same formula; but not substitute 3.14 into the answer.
V=π.4/3·r³
V=π·57.1666666667
Round 57.1666666667: 57.17
V=57.17π
Either one would work. Hope this works.

The length of a rectangle is 4/5 of the width. The length of the rectangle is 3/5 meter. Which equation can be used to find w, the width of the rectangle in meters?
A 3/5w = 4/5
B 4/5w = 3/5
C 3/5 + w = 4/5
D 4/5 + w = 3/5
Answer:
B: 4/5w = 3/5
Step-by-step explanation:
The length of the rectangle is stated as being 4/5 of the w. (4/5 * w)
The length is also stated specifically as being 3/5m so that will equal 4/5w on the other side of the equation.
Bonus:
You could work out the equation as
4/5w = 3/5m
multiply by 5
4w = 3m
divide by 4
w = 0.75m (or 3/4m)

what is the difference in the length between the longest meter in the shortest meter
Answer:
1 5/8 inches
Step-by-step explanation:
Hey there!
The question is asking what the difference in the length between the longest meteor and the shortest meteor is.
In the chart, the smallest measurment is 2/8 and the largest is 1 7/8
So in order to solve this you need to subtract these two values
we can convert 1 7/8 to 15/8 to make the subtraction more simple
15/8-2/8=13/8 which is 1 5/8
So the difference between the longest and shortest meteor is 1 5/8 inch
Answer: 1 5/8.
Step-by-step explanation: The longest one is 1 7/8 and the shortest one is 2/8. Both are circled below. To figure this problem out, we need to find the difference of the longest and shortest meteors, also known as a subtraction problem. The work is done below:
1 7/8 - 2/8 = 1 5/8.

An architect notices that the scale on a blueprint he is using has been torn off. However, he sees that a 21.6-foot wall that has been built is 6 inches long on the blueprint. What is the scale for this blueprint?
A. 1 in. : 3.6 ft.
B. 1 in. : 6.3 ft.
C. 1 in. : 36 ft.
D. 1 in. : 63 ft.
Answer:
The answer is - A. 1 in. : 3.6 ft.
Step-by-step explanation:
In order to get the scale on the blueprint we just have to divide the measure in real time by the number of the blueprint, if we know that there´s a wall that is 21.6 feet long, and in the blue print is 6 inches long we just divide it:
scale: 21.6/6
scale: 3.6
So, now we know that for every inch in the blueprint there has to be 3.6 feet on the real construction.

Draw the graph of the equation x+5y=6
Answer:
Step-by-step explanation:
A son is one half as old as his father. The some other ages is 72 years. What is the age of each?
Answer:
The son is 24 and the father is 48
Step-by-step explanation:
If you let x = the age of the child, then the father is 2x old since the father is twice as old as the son. The sum of their ages would be 1x + 2x which simplifies to 3x.
Since the problem gives the total of their ages as 72, we know that 3x = 72.
Dividing both sides by 3, we get x = 24, which we said was the age of the child.
Since the age of the father is 2x, we can say that 2x = 2(24), or 2x = 48 for the age of the father.
The flight of a javelin released six. 5 feet from the ground at an initial velocity of 68 ft./s is modeled by the function age equals 16 t^2+68t+6.5 where H is the height of the Javelin in feet after t seconds. When will the javelin hit the ground? Round to the nearest hundredth if necessary
The equation of the javelin path h(t) = -16t^2+68t+6.5 is a quadratic function
The javelin hits the ground after 4.344 seconds
How to determine when the javelin hits the ground?The equation of the javelin path is given as:
h(t) = -16t^2+68t+6.5
When it hits the ground, h(t) = 0.
So, we have:
-16t^2+68t+6.5 = 0
Using a graphing calculator, we have:
t = 4.344 and t = -0.094
Time cannot be negative.
So, we have:
t = 4.344
Hence, the javelin hits the ground after 4.344 seconds
