a rectangle has a length 12 meters and a width of 400 centimeters. what is the perimeter, in cm of the rectangle
Answers
Answer:
P= 3200 cm
Step-by-step explanation:
Perimeter = 2(l+w)
In this case since the perimeter has to be in centimeters, we have to change the length of the rectangle to centimeter.
12 meter to centimer = 12 x 100 = 1200 cm
2( 1200 +400)
2 (1600)
= 3200 cm

-2x+y=-3
Step-by-step explanation:
mr clean
2x+y=-3
on algebra, to move something to the other side of the equal sign you must make the variable cancel out.
so, in this case, we will add 2x to cancel out the -2x. after that rules of algebra state whatever we do to one side of the equal sign, we must do to the other. so we get 2x on the left side, resulting in 2x+y=-3

The girls varsity basketball team had 850 fans attend their first game of the season. For the second game they had 1037 fans attendance. What was the percentage increase in attendance?
Answers
Answer:
22%
Step-by-step explanation:
It's 22% because if we want to find the percent change in something, the formula for that is new number - (minus) old number, than divide by old number, and lastly multiply by 100. So,
1. 1037 - 850 = 187
2. 187 / 850 = 0.22
3. 0.22 x 100 = 22 --> 22%
You can find the derivative of the inverse function by differentiating the inverse explicitly, or by using the formula:
Answers
If a function f(x) has an inverse f ⁻¹(x), then by definition
[tex]f\left(f^{-1}(x)\right) = x[/tex]
Differentiating both sides with respect to x yields
[tex]f'\left(f^{-1}(x)\right) \times \left(f^{-1}\right)'(x) = 1 \implies \left(f^{-1}\right)'(x) = \dfrac1{f'\left(f^{-1}(x)\right)}[/tex]
Now, if f(a) = b and b = f ⁻¹(a), then
[tex]\left(f^{-1}\right)'(a) = \dfrac1{f'\left(f^{-1}(a)\right)} = \dfrac1{f'(b)}[/tex]

A family took a road trip and traveled west a distance of 350 kilometers in 7 hours. What was their velocity during this
Answers
Answer:
50 km/h
Step-by-step explanation:
so you traveled total of 350 (km) in 7 (hours) right?, just take 350, divide it by 7, which will give you km/h. (or 50 km/h) and then when you add a direction it like "west" it's no longer a speed it's a velocity.
Displacement given (in metres) = (350 × 1000)m.
Displacement = 350000 metres.
Time = (7× 3600) seconds
Time = 25200 seconds.
Velocity = Displacement / Time
Velocity = 350000 / 25200
Velocity = 13.89m/s
Approximately, Velocity = 14m/s.
A city park is in the shape of a rectangle with width of 25 yd. and length of 60 yd. What is the length of the diagonal that runs across the park?
A.
B.
C.
D.
Answers
Answer:
65 yd
Step-by-step explanation:
The diagonal of a rectangle can be found using
Pythagoras' Theorem a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Given:
a = 25b = 60⇒ 25² + 60² = c²
⇒ c² = 4225
⇒ c = √4225
⇒ c = 65
Therefore, the length of the diagonal is 65 yd

If 12 inches = 1 foot, how many inches are in 8 feet?
Answers
Answer:
96 inches
Step-by-step explanation:
Given the following question:
12 inches = 1 foot
To find the answer we simply need to multiply 12 by 8, since every 12 inches are equal to 1 foot and we need to find how many inches are in 8 feet.
[tex]12in=1ft[/tex]
[tex]8\times12=96[/tex]
[tex]=96in[/tex]
8 feet is equal to "96 inches."

A town had a population of 10,000 people. the population decreased 3% each year. what was the population 5 years later?
Answers
Answer:
8,588 people
Step-by-step explanation:
We can represent this exponential decay as [tex]P=10000(0.97)^n[/tex] where [tex]n[/tex] is the number of years later:
[tex]P=10000(0.97)^n\\\\P=10000(0.97)^5\\\\P=10000(0.8587340257)\\\\P=8587.340257\\\\P\approx8588[/tex]
Therefore, the population 5 years later will be 8,588 people
Step-by-step explanation:
Ok so after the first year we expect the population to reach 97% of it's initial population.
So 97% of 10 000 can be written as:
97/100 ×10 000=0.97×10 000=9 700
After the second year we expect the population to drop to 97% of the first year's population
So, it can be said that:
0.97×9700= 9409
Similarly after year 3,
0.97× 9409= 9126.73
Year 4,
0.97× 9126.72= 8852.9281
Year 5,
0.97× 8852.9281=8587 rounded to the nearest number
The new population would be 8587
