Answer:
The account will grow to 1,000 in 5 years.
Step-by-step explanation:
Since the account will become 1000, the interest is 90 dollars. I=p*r*t.
90=910*.021*t
90=19.11*t.
t=4.71, so it will take 5 whole years.
Answer:
Rock D.
Step-by-step explanation:
We can assume that the force that the catapult does is always the same.
So, here we need to remember Newton's second law:
F = m*a
force equals mass times acceleration.
Where acceleration is the rate of change of the velocity.
So, if we want the rock to hit closer to the catapult, the rock must be less accelerated than rock B.
So, we can rewrite:
a = F/m
So, as larger is the mass of the rock, smaller will be the acceleration of the rock after it leaves the catapult (because the mass is in the denominator). So if we want to have a smaller acceleration, we need to choose a rock with a larger mass than rock B.
Assuming that the mass depends on the size, the only one that has a mass larger than rock B is rock D.
So we can assume that rock D is the correct option.
Hey there!
Let's start by finding what 1% of 210 is.
This can be done by dividing 210 by 100, since 1% is the same as 1/100 of something.
210 ÷ 100 = 2.1
To find 36%, we can multiply 2.1 by 36.
2.1 x 36 = 75.6
So, 36% of 201 is 75.6.
Hope this helps!
