Give your answer as a whole number of years.
Answer: It would take 24 years to double your investment.
Hope this helps!
Sam will have doubled his investment for 33 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Sam invests a sum of money into an account that pays 3%
compound interest per annum
We need to find how many years Sam will have doubled his investment.
With C your initial capital, k the interest rate and t the number of years. Since k is given as a simple interest rate, you’re essentially trying to solve :
C(1+tk)=2C
With a little bit of algebra, you should find that:
t=1/k
k=3%=0.03
t=1/0.03=33.33=33 years.
Hence, Sam will have doubled his investment for 33 years.

Answer:
Second choice.
Step-by-step explanation:
Option 1: solve the inequality. Add 7 to both sides, and multiply by -3 (don't forget that this makes the inequality switch direction!) to get [tex]x > {27 \over {-3}[/tex] or x > -9
Option 2. Plug 0 in it. You get -7 < 20, which is obviously true. So 0 is in the set of solution and it means B and C are possible solutions. So let's check another easy value. let's say -10. replacing it you get [tex]-3 (-10) -7 < 20[/tex] or [tex]30 -7 <20[/tex]. But 23 is obviously greater than 20, which means -10 is not a part of the solution. Correct answer is B

It takes 10 seconds to move 1 centimeter. How long will it take the snail to move 2.5 centimeters
Answer:
25 sec
Step-by-step explanation:
2.5 cm is 2.5 times 1 cm, so it will take 2.5 times 10 seconds.
2.5 * 10 sec = 25 sec
The snail take 25 seconds to move 2.5 centimeters.
What is Measurement unit?
A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Given that;
The snail take 10 seconds to move 1 centimeter distance.
Now,
For covering 2.5 centimeters , the time is calculated as;
Since,
The snail take 10 seconds to move 1 centimeter distance.
That is,
⇒ 1 centimeter = 10 seconds
Hence, For the distance 2.5 centimeter, the time is;
⇒ 1 centimeter = 10 seconds
⇒ 2.5 centimeter = 2.5 × 10 seconds
= 25 seconds.
Thus, The snail take 25 seconds to move 2.5 centimeters.

Answer:
x= 7
B= 112
F= 68
Step-by-step explanation:
to find x we set up an equation, (16x)=(4x+84). They are alternate interior angles which are always equal.
calculate it and you'll find x=7.
B and the angle 4x+84 are equal because they are vertical angles, to find it we just put 7 instead of x into 4x+84.
4(7)+84=112
angle f is supplementary to 16x. 16x is also 112 because they are equal, so its just 180-112=68

what is the Greatest Common Factor and the Least common Multiple os 3 and 8
3 is a prime number - the GCF is 1, and the least common multiple of 3 and 8 is 24.
Answer:
Greatest Common Factor is 1
Least Common Multiple is 24
Step-by-step explanation:
Greatest common factor is the biggest whole number that can be multiplied into the numbers. In this case 1x8=8 and 1x3=3.
Least common multiple is the smallest number each number can multiply into. In this case 3x8=24 and 8x3=24

Using the sine ratio in the right triangle and the exact value
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

Answer:
Points ( 0, 13) , ( 30, 18) , ( 90 ,28)

Answer:
64 ounce bottle of orange juice has a greater percent of water
Step-by-step explanation:
Case 1) An 80 ounce bottle of apple juice contains 32 ounces of water
Total quantity of bottle = 80 ounces
Amount of water = 32 ounces
So, Percent of water = [tex]\frac{32}{80}[/tex] x 100
= 40%
Case 2) An 64 ounce bottle of orange juice has 48 ounces of water
Total quantity of bottle = 64 ounces
Amount of water = 48 ounces
So, Percent of water = [tex]\frac{48}{64}[/tex] x 100
= 75%
Hence 64 ounce bottle of orange juice has a greater percent of water
