A rabbit weighs 2.8 kilograms. How many grams does the rabbit weigh? Use the number of zeros of the product when multiplying a number by
power of 10 to help you. (1 point)
2,800 grams
28 grams
28,000 grams
280 grams
Answer:
Option A
Step-by-step explanation:
Given data
We are told that the weight of the rabbit is 2.8 kilograms
We also want to convert from kilograms to grams
We know that 1kg= 1000 grams
Hence 2.8 kg= x gram
Cross multiply
x= 2.8*1000
x= 2800 grams
Hence the weight in grams is 2800grams
Option A is correct
Answer:
it is A
Step-by-step explanation:
2,800

An inlet pipe can fill a water tank in 12 hours. An outlet pipe can drain
the tank in 20 hours. If both pipes are mistakenly left open, how long will
it take to fill the tank?
============================================================
Explanation:
Let's consider the tank's full capacity is 240 gallons. I'm picking this number because 12*20 = 240.
If the tank is 240 gallons, then the inlet pipe can fill it at a rate of 240/12 = 20 gallons per hour. Note after 12 hours, we have 12*20 = 240 gallons filled assuming the outlet pipe is sealed shut.
At the same time, the outlet pipe is draining at a rate of 240/20 = 12 gallons per hour. After 20 hours, the outlet pipe would drain out 12*20 = 240 gallons assuming the inlet pipe is not adding any water.
With the two pipes playing this tug-of-war battle, the inlet pipe ultimately wins because it's adding more gallons of water each hour, compared to the amount drained per hour. The net change is +20-12 = 8 gallons per hour.
This means it will take 240/8 = 30 hours to fill the tank with both pipes open.
----------------------------------
Another approach:
The inlet pipe can fill the tank in 12 hours, so it gets 1/12 of the job done per hour. The outlet pipe drains the tank in 20 hours, so it gets 1/20 of the job done in one hour.
The net change is 1/12 - 1/20 = 5/60 - 3/60 = 2/60 = 1/30
This means that when both pipes are open, 1/30 of the job is done per hour. By "job", I mean "filling the tank".
If x is the number of hours needed to do one full job, then we can multiply that by the unit rate (1/30) and set the result equal to 1
(rate)*(time) = 1 job
(1/30)*x = 1
x = 30*1
x = 30
It takes 30 hours to do the job with both pipes open.

Oliver, Lily, and Ella are hoping to save money. Oliver thinks saving money in a shoe box in his closet every month is a good idea. He decides to start with $150, and then save $75 each month. Lily was given $4000 from her Great Uncle Merv, and decides to put the money into an account that has a 7% interest rate that is compounded annually. Ella has earned $4500 working at the gas station and decides to put her money in the bank in an account that has a 7.5% interest rate that is compounded continuously.
the question is Describe the type of equation that models Ella’s situation. Create that equation of Ella’s situation. Using the equation you created, how much money will be in Ella’s account after 2 years? 10 years?
You'd first have to divide the first to, then add an divide your sume by the percent to get your answer.
Answer:
Step-by-step explanation:
Use formulaic methods. Since she has interest on her money, we have to include it:
i = log(x-4*7)^k
i is the interested amount, x is the variable we use, and k is the number of times. 7 is the interest
i = log(4000-4x7)^2 for 4000 at 7% interest over 2 years
i = log(4000-4x7)^10 for 4000 at 7% interest over 10 years
Amount after 2 years: $30,000
Amount after 10 years: $15,671

Simplifies to:
−x+1/9=5
Let's solve your equation step-by-step.
−x+1/9=5
Step 1: Subtract 1/9 from both sides.
−x+1/9−1/9=5−1/9
−x=44/9
Step 2: Divide both sides by -1.
−x/−1=44/9/−1
x=−44/9

Answer:
rules of exponents apply
Step-by-step explanation:
The applicable rules of exponents are ...
a^-b = 1/a^b
(a^b)(a^c) = a^(b+c)
__
Applying those rules to the given equation, you get ...
[tex]\left(\dfrac{1}{5}\right)^4\cdot\left(\dfrac{1}{5}\right)^2=5^{-6}\\\\ \left(\dfrac{1}{5^4}\right)\cdot\left(\dfrac{1}{5^2}\right)=5^{-6}\\\\ (5^{-4})(5^{-2})=5^{-6}\\\\5^{-4-2}=5^{-6}\\\\5^{-6}=5^{-6}[/tex]

Answer:
88
Step-by-step explanation:
If $18\sqrt 8-8\sqrt{18}=\sqrt n, what is n?
Answer:
288 trust me it is 100% right I tried it as an answer an got it right.
Step-by-step explanation:
Answer:
288
Step-by-step explanation:
From the first two parts of the problem, we have
18√8 - 8√18 = 36√2 - 24√2
= (36 - 24)√2
= 12√2.
Thus, we wish to solve for n in the equation 12√2 = √n. In other words, we want to know what number 12√2 is the square root of. Any nonnegative number is the square root of its own square, so
n = (12√2)²
= 12²(√2)²
= 144 ∙ 2
= 288.
which of this numbers should go inside the box to make the equation true blank plus 4 over 2 equals 10
Given:
The expression is
[tex]\dfrac{\_\_\_+4}{2}=10[/tex]
To find:
The number of the blank.
Solution:
Let x be the missing number for the blank. Then,
[tex]\dfrac{x+4}{2}=10[/tex]
Multiply both sides by 2.
[tex]x+4=20[/tex]
Subtract 4 from both sides.
[tex]x=20-4[/tex]
[tex]x=16[/tex]
Therefore, the missing number for the blank is 16.
