Answer: in explination
Step-by-step explanation:
annual interest = .05(4000) = 200
to double, you need another $4000
number of years = 4000/200 = 20
annual interest = .05(4000) = 200
to double, you need another $4000
number of years = 4000/200 = 20
it will take 20 years
to check if you are right you would...
Check:
simple interest on $4000 for 20 years at 5%
= .05(20)(4000) = 4000
the amount = what we had + new amount
= 4000 + 4000 = 8000 which is double what we started with
So the answer would be it took 20 years.
0.5m + 2 = 7.5 please I don’t understand
Answer:0
. 5 + 2 = 7 . 5
1 2 + 2 = 7 . 5
Step-by-step explanation:
Answer:
m = 11
Step-by-step explanation:
0.5m + 2 = 7.5
0.5m + 2 - 2 = 7.5 - 2
0.5m = 5.5
0.5m ÷ 0.5 = 5.5 ÷ 0.5
m = 11

A division problem has 43 as its divisor. Then the value of the dividend will be 1,180.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The formula is given as,
Dividend = Quotient × Divisor + Remainder
A division issue has 43 as its divisor. The halfway remainder are 20 and 7. The rest of 19.
Dividend = (20 + 7) × 43 + 19

Determine the domain on which the following function is increasing. Will give brainlist if correct
Answer: D : x ∈ (1, ∞)
Step-by-step explanation:
for a function y = f(x)
The range is the set of possible values of y.
The domain is the set of the possible values of x.
We want to find the domain on which the function is increasing.
A function is increasing if, reading from left to right, the "y" value of the function increases (or the graph goes upward)
Then we need to see on which point the graph starts going up. We can see that this happens at the vertex of the parabola, at x = 1, and it keeps increasing infinitely.
then we can write this domain as:
D : x ∈ (1, ∞)

A bag contains 37 coins consisting of only dimes and quarters.The total amount of money in the bag is $6.85. How many dimes are in the bag ??
Answer:
16 dimes
Step-by-step explanation:
D=number of dimes
Q=number of quarters
D+Q=37
.25 xQ + .10 x D=6.85
sub Q from first equation
.25(37-D) + .10 x D=6.85
D(.10-.25) + .25 x 37 =6.85
-.15D + 9.25=6.85
D= (6.85-9.25)/(-.15)
D=16
3(r+2)+5(2-r) =-32 can someone tell em the answer to that please
Answer:
r = 24
Step-by-step explanation:
3(r+2)+5(2−r)=−32
Step 1: Simplify both sides of the equation.
3(r+2)+5(2−r)=−32
(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)
3r+6+10+−5r=−32
(3r+−5r)+(6+10)=−32(Combine Like Terms)
−2r+16=−32
−2r+16=−32
Step 2: Subtract 16 from both sides.
−2r+16−16=−32−16
−2r=−48
Step 3: Divide both sides by -2.
−2r/-2 = -48/-2
r = 24
Answer: r = 24
3(r+2)+5(2-r) =-32
this equals (if we do the multiplication)
3r+6+10-5r=-32
this equals (if we simplify)
-2r+16=-32
this equals (because we are subtracting from 1 side, we must subtract from the other)
-2r=-48
r=24

The radius of a circle is 10 cm. What is the approximate area of the circle? What is the exact area of the circle? Show your work.
First let's review the area formula for a circle.
Area=π[tex]r^2[/tex]
Now that we know the radius, r is 10. The area is
10*10*π=100π
I will approximate π to 3.14 although you could do it more precise or less precise. The final answer will be 100*3.14=314 squared centimeter.
Any question you have about this just ask in the comment of this answer :)

PLEASE HELP, find the orthocenter of this triangle
Answer:
The orthocenter of a triangle is the point at which the three altitudes of a triangle intersect. This involves creating 3 lines, one from each vertex (K, L, and M) perpendicular to the line segment opposite it, so K⊥LM, L⊥KM, and M⊥KL.
Because these three lines intersect at one point, you only need to do this procedure for two of the three altitudes. Because K and M are on the same Y coordinate (-4), lets do this for LM and KL
First, we need to find the slope of the perpendicular to each line segment, so we need the slope of LM and KL.
The slope is the change in Y over the change in X
Slope LM = 6 -(-4) / 2-7 = 10/-5 = -2
Slope KL = -4-(6) / 4-2 = -10/2 = -5
The slope of a perpendicular line is the negative reciprocal of the slope of the given line, so for
the slope of K⊥LM has to be 1/2 and
the slope of M⊥KL has to be 1/5
Second, the vertex has to be on a line with that slope. So using the point-slope formula
(y-y1) = m(x-x1) , where x1,y1 is a point on the line for each line gives us
K⊥LM: y-(-4) = 1/2(x-4)
M⊥KL: y-(-4) = 1/5(x-7)
Third, find the point on both lines, are where the two equations are equal
So, 1/2(x)-2 = 1/5(x) - 7/5;
5x - 20 = 2x - 14
3x = 6 --> x=2
y+4=-1 --> y=-5
