An object is moving at a speed of 4 meters per month. Express this speed in inches
per hour. Round your answer to the nearest hundredth.
*Note: you must use these exact conversion factors to get this question right.
Distance / length
Time
1 foot (ft) = 12 inches (in)
1 minute (min) = 60 seconds (sec)
1 yard (yd) = 3 feet (ft)
1 hour (hr) = 60 minutes (min)
1 mile (mi) = 5280 feet (ft)
1 day (day) = 24 hours (hr)
1 meter (m) = 100 centimeters (cm)
1 week (week) = 7 days (days)
1 kilometer (km) = 1000 meters (m)
1 month (month) = 30 days (days)
1 inch (in) = 2.54 centimeters (cm)
1 year (year) = 365 days (days)
1 foot (ft) = 0.305 meters (m)
1 mile (mi) = 1.609 kilometers (km)
Answer:
0.22inches/hourStep-by-step explanation:
Given the speed of an object to be 4metres/month, we are to express the speed in inches/hour.
First we will need to convert 4meters to inches
From the conversion factors given,
1 foot (ft) = 0.305 meters (m)
x ft = 4metres
cross multiply
x * 0.305 = 4*1
x = 4/0.305
x = 13.115ft
4 metres = 13.115ft
Then we will convert 13.115ft to inches
From the conversion factors,
1 foot (ft) = 12 inches (in)
13.115ft = y
cross multiply
y = 13.115*12
y = 157.377 inches
Hence 4 metres = 157.77inches.
For 1 month to hour
First we need to convert month to days and from the conversion factor
1 month = 30 days
Next is to convert 30days to hours
Since 1 day = 24hours
30days = z
z = 30* 24
z = 720hours
Hence 1 month = 720hours
On converting 4metres/month to inches/hour
4metres/month = 157.77inches/720hours
4metres/month = 0.219inches/hour
Hence the speed of the object in inches per hour to the nearest hundredth is 0.22inches/hour

how many pennies fit in a 22-inch circle?
Answer :
663 Pennies can fit into a 22-inch circle
The required number of pennies fit in the circle is 13.
Area of the Circle:The formula of the area of the circle is [tex]A=\pi r^2[/tex]
As we know that the standard radius of a penny is 0.75 inch
So, the area of the one penny is,
[tex]A=\pi r^2\\A=3.14\times (0.75)^2\\A=1.77[/tex]
So, the total number of pennies fit in the 22-inch circle is,
[tex]n=\frac{22}{1.77} \\n=12.49\\n\approx 13[/tex]

A nurse mixes 50 cc of a 60% saline solution with a 10% saline solution to produce a 20% saline solution. How much of the 10% solution should he use?
Answer:
The nurse should use 200cc of the 10% saline solution in order to produce a 20% saline solution.
Step-by-step explanation:
to the given mix we add a quantity of a lower mix to generate another.
50cc at 60% + Xcc at 10% = (50 + X)cc at 20%
50 x 60% + X x 10% = (50 + X) x 20%
30 + 0.1X = 10 + 0.2X
30 - 10 = 0.2X - 0.1X
20 = 0.1X
20/0.1 = X
X = 200
16. Rahul cycles at a speed of 6km/hr to reach school in 20 minutes. What should his
speed be if he wants to reach school in 15 minutes?
Step-by-step explanation:
Distance to school = (6km/h)(1/3h) = 2km
2km in 15 minutes = 8km in 60 minutes.

Convert 32,190 inches /year to yards
Answer:
2.4 yards a day
Step-by-step explanation:
32,190 inches = 894.167 yards
894.167 / 365 = 2.4 yds/day
The conversion of 32,190 inches /year to yards/day yields: 2.4 yards/day
To convert 32190 inches/year to yards per day;
We must first find the conversion factor of inches to yards andWe must also find the conversion factor of years to days.In essence, since 1 inch = 0.0278 yards.
Therefore, we have;
32190 inches/year = 32190 × 0.0278 yards/year.= 894.88yards/year.However, 365 days make one year;
Therefore,
894.88 yards/year = (894.88/365) yards/day.= 2.4 yards/day.

What type of move takes Figure A to Figure B?*
Answer: Rotation
Step-by-step explanation:
From the figure , we can observe that both figure A and b are absolutely congruent.
To translate a figure to make congruent images , we use rigid motions (Translation, Reflection, Rotation)
It is Rotation because of we move Figure A 180 degrees clockwise about the fixed point O, we will get Figure B .
It cannot be reflection because both figures are not mirror images.
It cannot be translation because all points on Figure A is not moving , as point O remained at same position throughout this which is not possible in translation.

An average African elephant weighs about 9,072 pounds. How is this number written in scientific notation?
Answer:9.072×10³
Step-by-step explanation:
A number is said to be written in a scientific notation or standard form if it is expressed in the form a×10n where 1 is less than or equal to a and a is less than 10 and n is an integer
9072 is more than 10
So 9072÷10=907.2
Still 907.2 is more than 10
So 907.2÷10=90.72
Still 90.72 is more than 10
So 90.72÷10=9.072
9.072 is less than 10
We divided 9072 by 1000 and 1000 as a power of ten is 10³
So the answer is 9.072×10³

If I fall for 18 s what would my final velocity be, if I started from rest.
Answer:
176.58 m/s
Step-by-step explanation:
assume that the acceleration due to gravity, g = 9.81 m/s²
I also assume we neglect air resistance (hence we assume no terminal velocity)
recall that one of the equations of motions can be expressed as
v = u + at, where
u = initial velocity = 0 (because it says you started from rest)
v = final velocity (we are asked to find this)
a = acceleration due to gravity = 9.81 m/s²
t = time = given as 18s
simply substitute the above into the equation.
v = 0 + (9.81)(18)
v = 176.58 m/s

Answer:

Step-by-step explanation:
LN = 6x
LN = LM + MN ➡ LN = 4x + 8 + 27 so 6x = 4x + 8 + 27
2x = 35 and x = 17.5
6 × 17.5 = 105
Answer:
105
Step-by-step explanation:
4x+8+27=6x
subtract 4x from both sides you get 35 = 2x
divide and get x= 17.5
you know LN = 6(x), so substitute 17.5 in for x and you get 6(17.5)= 105
