Greg saved $6000 in his bank account. His account interest rate is 2.5%. What will be the amount of interest earned after 5 years?
Answer:
$6750...............
SI = P*R*T/100
SI = 6000*2.5*5/100
SI= $750
amount= P+SI
Amount= 6000+750
Amount= $6750
What is the ratio in which the point P(3/4,5/12) decides the line segment joining points A(1/2,3/2) and B(2,-5)
Given:
The point [tex]P\left(\dfrac{3}{4},\dfrac{5}{12}\right)[/tex] divides the line segment joining points [tex]A\left(\dfrac{1}{2},\dfrac{3}{2}\right)[/tex] and [tex]B(2,-5)[/tex].
To find:
The ratio in which he point P divides the segment AB.
Solution:
Section formula: If a point divides a segment in m:n, then the coordinates of that point are,
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Let point P divides the segment AB in m:n. Then by using the section formula, we get
[tex]\left(\dfrac{3}{4},\dfrac{5}{12}\right)=\left(\dfrac{m(2)+n(\dfrac{1}{2})}{m+n},\dfrac{m(-5)+n(\dfrac{3}{2})}{m+n}\right)[/tex]
[tex]\left(\dfrac{3}{4},\dfrac{5}{12}\right)=\left(\dfrac{2m+\dfrac{n}{2}}{m+n},\dfrac{-5m+\dfrac{3n}{2}}{m+n}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{3}{4}=\dfrac{2m+\dfrac{n}{2}}{m+n}[/tex]
[tex]\dfrac{3}{4}(m+n)=\dfrac{4m+n}{2}[/tex]
Multiply both sides by 4.
[tex]3(m+n)=2(4m+n)[/tex]
[tex]3m+3n=8m+2n[/tex]
[tex]3n-2n=8m-3m[/tex]
[tex]n=5m[/tex]
It can be written as
[tex]\dfrac{1}{5}=\dfrac{m}{n}[/tex]
[tex]1:5=m:n[/tex]
Therefore, the point P divides the line segment AB in 1:5.

Answer:
x = 70
Step-by-step explanation:
As the problem states, ∠ABD and ∠DBC are supplementary angles. This means they have a sum of 180°. Since we know this, we can set up an equation to solve for x.
x + 110 = 180
x = 70

Find the coordinates of the point that is located 8 units below the x-axis and 3 units to the left of the y-axis
can someone set this up and solve to find the missing angle measurements i swear they do to much wit math
Answer:
angle with a straight line has measure equal to 180°
Step-by-step explanation:
29°+112°+<z°=180°
141°+<z°=180°
group like terms
<z°=180°-141°
<°z=39°
1/3 (9x-10) = 4 I need the answer and how you solve it
Answer:
X=22/9
Step-by-step explanation:
Multiply both sides by 3
Giving u 9x-10=12
Put x on one side
9x=12+10
9x=22
Divide both sides by 9 :)

Using compound interest, it is found that the investment will be worth $36,466.76 in 30 years.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.The parameters are given as follows:
P = 12, r = 0.12, n = 52, t = 30.
Hence the amount is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]A(30) = 1000\left(1 + \frac{0.12}{52}\right)^{52 \times 30}[/tex]
A(30) = $36,466.76

Answer:36,446.76
Step-by-step explanation:
From the question we can see our given values are P=1,000, r=0.12, n=52, and t=30. Plugging this into our compound interest formula will give us our solution.
A(t)A(30)=P(1+rn)nt=1,000(1+0.1252)52⋅30≈36,446.76

. In a group of 37 people waiting in line at the local java house, 18 wanted to order a cappuccino, 20 wanted to
order a latte, and 2 wanted neither of these drinks. How many wanted to order both a cappuccino and a latte?
Answer:
36
Step-by-step explanation:
Its 36 because normally someone would do 18+20=38 but you have to remeber in the problem it says 37! so 2 people didn't want anything, minus that and you get 36.

A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it win to finish the season with a 90% winning percentage?
Answer: The team needs to win 15 more games to get 90% winning percentage.
Step-by-step explanation:
80%=4/5 divide 15 by 5 and you get 3, which is 1/5 of 15, so you must multiply it by 4 to get 80% of 15 which is 3*4=12
If you want 90%(or 9/10) of 30, you do the same thing, and you get 27.
27-12=15.
The team needs to win 15 more games to get 90% winning percentage

Answer:
42
Step-by-step explanation:
3/(3+x-6)=5/(5+x)
cross multiply
3(5+x)=5(3+x-6)
15+3x=15+5x-30
15+3x=5x-15
15+15=5x-3x
30=2x
x=15
That means KQ=15 and PK=15-6=9. Now we have to find PQ, which is the same as JM. We’ll call that length b.
5/15=6/b
cross multiply
5b=90
b=18
15+9+18=42

Some people believe there are too many taxes and that tax rates
are too high. They refuse to file tax returns or pay taxes because
they disagree with how the government spends the money. Do you
agree with these arguments? Why or why not?
Answer:
Step-by-step explanation:
(This is technically a personal opinion question) In MY opinion all government run things from libraries to schools to the military come from taxes. If you don't agree with how the government spends the money that you pay in taxes yet enjoy/use government facilities then you have no room to complain and not pay your taxes.
