Answer:
<h2>124.1m</h2>
Step-by-step explanation:
29.4 per sec > Building 80m
Height = S = 4.9t^2 + 29.4t + 80
Solve for t:
t = 1.24 (approximately)
If t needed coordinates / solve using the quadratic formula:
t = (1.24 , -7.24)
<h3>The ball's maximum height is 124.1 meters.</h3>

Skippy should invest $ 7500 in account offering 4 % interest and $ 2500 in account offering 8 % simple interest
<em><u>Solution:</u></em>
Given that Skippy has a total of $10,000 to split between two investments
One account offers 4% simple interest, and the other account offers 8% simple interest
Total interest earned = 500
Number of years = 1
Let the principal with rate of interest 4 % is x
So the principal for rate of interest 8 % is 10000 - x
Total interest earned = simple interest for 4 % interest + simple interest for 8 % interest
Simple interest is given as:
Where "p" is the principal and "r" is the rate of interest and "n" is the number of years
Therefore,
Therefore skippy should invest $ 7500 in account offering 4 % interest
And skippy should invest (10000 - x) = (10000 - 7500) = $ 2500 in account offering 8 % interest
Answer:
a. 3, 1, 1, 1, 1, 1
b. 7, 1, 1, 1, 1, 1
c. can't do if throwing all 6 darts
d. 9, 9, 7, 1, 1, 1
e. can't do, as throwing 6 9s only gives us 54 points.
Step-by-step explanation:
We throw 6 darts, each yields us a score of 1, 3, 5, 7 or 9.
We need to answer how we could make a total of:
a. 8
b. 12
c. 27
d. 28
e. 56
I am not entirely clear as to if throwing fewer than 6 darts is allowed, but we'd only need it for c.
The reason we need to throw fewer than 6 for c. is that all the scores are odd, so adding 6 odd scores will always give an even score.
We can create the scores by throwing for the highest score that lets us throw the remaning darts at 1 or more.
a. 3, 1, 1, 1, 1, 1
b. 7, 1, 1, 1, 1, 1
c. can't do if throwing all 6 darts
d. 9, 9, 7, 1, 1, 1
e. can't do, as throwing 6 9s only gives us 54 points.
Step-by-step explanation:
Take John's sister's age as "x"
So, so twice his sister's age means = 2x
And 5 years more, means = 2x + 5
So finally John's age = 2x + 5
