Convert 5 square meters to square centimeters. Explain
Answer:
5 sq m = 50,000 sq cm
5 sq m = 5 sq m
Step-by-step explanation:
To convert a square meter measurement to a square centimeter measurement, multiply the area by the conversion ratio.
Since one square meter is equal to 10,000 square centimeters, you can use this simple formula to convert:
square centimeters = square meters × 10,000
Answer:
50000 square centimeters.

Planet Q Is 3.6 x 10^6km
Planet R Is 1.6 x 10^7km
What Is The Shortest Distance Between Planet Q And R (Answer In Standard Form)
I've Been Stuck On This Question For A Vast Amount Of Time.
Answer:
1.64×10⁷ km
Step-by-step explanation:
We know this is a triangle rectangle, so we apply the Pythagorean Theorem
QR=sqrt(PR²+PQ²)
Solving it, we will encounter in
sqrt(2.56×10¹⁴+1.296×10¹³)
to solve it, we need to bring the two numbers at the same power of ten, so we move 1.296 of one place to the left:
sqrt(2.56×10¹⁴+0.1296×10¹⁴)
we can now add the two numbers:
sqrt(2.6896×10¹⁴)
to solve this, we do the square root of 2.6896 and divide 14 by two (the index of the root is 2, so for roots' properties we can divide 14 by 2 - the index)
which gives us
1.64×10⁷

A restaurant tablecloth is 98 inches across. What is the approximate circumference?
The circumference of a circle with diameter of 98 in. is about 308 in.
Step-by-step explanation:We know the diameter. Using the diameter, we can find the circumference.
=> Diameter = 98 in.=> Radius = 98/2=> Radius = 49 in.Circumference = 2πr
=> 2 x 22/7 x 49=> 2 x 22 x 7=> 308 in.Conclusion:Therefore, the circumference of a circle with diameter of 98 in. is about 308 in.

Answer:
A = 80π
Step-by-step explanation:
Area of a circle is A = πr²
Area of the the largest circle - Area of the smaller circle = the shaded part.
Largest circle - Area of the smaller circle = Shaded part of circle
A = π(12)² - A = π(8)²
144π - 64π = 80π
An office clerk earns $120 for two 4-hour work shifts. How much will she earn
for 15 hours of work?
Answer:
$225
Step-by-step explanation:
$120 for 2 4-hour shifts, $120 in 8 hours
$15 every 1 hour
Money for 15 hours: 15 x 15 = $225
The office clerk earns $225 for 15 hour of work .
What is unitary method?The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
According to the question
An office clerk earns $120 for two 4-hour work shifts.
i.e
In 2 * 4-hour work shifts office clerk earns = $120
or
In 8 hour work shifts office clerk earns = $120
Now ,
By using unitary method
In 1 hour work shifts office clerk earns = $[tex]\frac{120}{8}[/tex]
= $15
Therefore, for 15 hours of work shifts office clerk earns = $15 * 15
= $225
Hence, The office clerk earns $225 for 15 hour of work .

Which equation has the same solution as w / 3.9 = 3? A. w+0.6=1.9 B. w-0.6 = 11.1 C. w+1.03=2.93 D. w-1.03=8.24
The equation has the same solution as w / 3.9 = 3 is w+0.6=1.9
Given:
w / 3.9 = 3
cross multiply
w × 3 = 3.9
3w = 3.9
divide both sides by 3
w = 3.9 / 3
w = 1.3
Check all that applies
A. w+0.6=1.9
w = 1.9 - 0.6
w = 1.3
B. w-0.6 = 11.1
w = 11.1 + 0.6
w = 11.7
C. w+1.03=2.93
w = 2.93 - 1.03
w = 1.9
D. w-1.03=8.24
w = 8.24 + 1.03
w = 9.27
Therefore, the equation has the same solution as w / 3.9 = 3 is w+0.6=1.9
