How much interest is earned in 2 years on an investment of $2,000? The interest rate
is 3%
A. 1200
B. $60
C. $600
D. $120
Please help I will give brainlist
Answer:
D. $120
Explanation:
P= principal amount, which is $2000 in this case
R= interest rate. In this case, it's 3% per year (or 0.03 in decimal form)
T= time, which in this case is 2.
To find the simple interest, we multiply 2000 × 0.03 × 2 to get 120.
I hope this helped! :)

Consider this function.
(r) = -3r + 3
Which graph represents the inverse of function ?
9514 1404 393
Answer:
C. graph Y
Step-by-step explanation:
Starting with f(r) = -3r +3, the inverse function can be found from ...
r = f(y)
r = -3y +3
r -3 = -3y
(r -3)/-3 = y
y = -1/3r +1
The inverse function will have a slightly negative slope and a y-intercept of 1. This matches graph Y.

Question is below thanks
Answer:
33.51
Step-by-step explanation:
There's a formula using the value of the angle but I don't remember it so the most easy way is:
A circle has an angle of 360°
so our section has an angle of 60
and we know that 360=60*6
so the area of the circle we divide it by 6 and we get the area we want
[tex]A=\pi r^2\\\\A=\pi (8)^2\\\\A=64\pi[/tex]
divide this by 6
[tex]A_1=A/6=64\pi/6\approx 33.51[/tex] units squared

abc has two side lengths of 8ft and 19 ft. if angle c is 142 degrees what is the measurement of angle B
15.) whats the approximately measure of one interior angle of the regular polygon shown
16.) the shape in the figure is a square . Use the properties to determine the value of X
Answer:
15) For a regular polygon of N sides, the measure of one interior angle is:
A = (N - 2)*180°/N
In this case, the figure has 11 sides, then we have N = 11, and the measure of each interior angle will be:
A = (11 - 2)*180°/11
A = 9*180°/11 = 147.27°
Rounding to the first decimal after the decimal point, we get:
A = 147.3°
Then the correct option is B.
16) We know that the length of all the sides of a square is the same.
In the image, we can see that the length of the right side is 4, and the length of the top side is 2x + 4
And those lengths must be the same, then we have the equation:
2x + 4 = 4
subtracting 4 in each side of the equation we get:
2x + 4 - 4 = 4 - 4
2x = 0
The only solution for this equation is x = 0.
Then the correct option is C
Which calcuation and answer show how to convert 5/16 to a decimal?
x - 2y =0
3x + y = 0
solve using the substitution method
to solve the linear system
Answer:
x=0, y=0
Step-by-step explanation:
① Label the 2 given equations.
x -2y= 0 -----(1)
3x +y= 0 -----(2)
② Make x the subject of formula in equation (1).
From (1): x= 2y -----(3)
③ Substitute equation (3) into (2):
3(2y) +y= 0
Expand:
6y +y= 0
Simplify:
7y= 0
y= 0
④ Find x.
Subst. y=0 into (3):
x= 2(0)
x= 0

4 x 10^3 times what number is equal to 16 x 10^3
The number which is 4 x 10^3 times equal to the number 16 x 10^3 after is number 4.
What is the product?Product is the resultant number which is obtained by multiplying a number with another. Let a number a is multiplied by number b. Then the Product of these two number will be,
[tex]P=a\times b[/tex]
Here, (a, b) are the real numbers.
The 4 x 10^3 times a number is equal to the number 16 x 10^3 Let suppose this number is n. Thus,
[tex]4\times10^{3}\times n=16\times10^{3}[/tex]
Divide both side of the equation with 4 x 10^3 as,
[tex]n=\dfrac{16\times10^{3}}{4\times10^{3}}\\n=\dfrac{16}{4}\\n=4[/tex]
Hence, the number which is 4 x 10^3 times equal to the number 16 x 10^3 after is number 4.

What is the length of AB?
O A. 9
O B. 18
O C. 48
D. 6
=====================================================
Explanation:
Draw in the segments AO and OC.
Triangle ABO is congruent to triangle CBO. We can prove this through the use of the HL theorem. HL stands for hypotenuse leg.
Since the triangles are congruent, this means the corresponding pieces AB and BC are the same length.
Then we can say:
AB+BC = AC .... segment addition postulate
AB+AB = AC .... plug in BC = AB
2*AB = AC
2*AB = 18
AB = 18/2 .... divide both sides by 2
AB = 9
In short, the chord AC is bisected by the perpendicular radius drawn in the diagram. So all we do is cut AC = 18 in half to get AB = 9.

On Christmas Eve, Charlie ate 20% of the gingerbread cookies he baked. If he ate 11 cookies, what was the total number of cookies he baked?
Answer:
22
Step-by-step explanation:
Charlie baked total of 55 cookies if he ate 11 cookies which is the 20% of the total cookies.
What is Percentage?The ratio or number in terms of the fraction per 100 is called the percentage. This concept is mainly used to calculate the proportion of any value with respect to the original value.
Symbol representing the percentage is %.
Let x be the number of cookies Charlie baked.
Percentage of cookies Charlie ate = 20%
Number of cookies Charlie ate = 11
That is, Charlie ate 20% of the total cookies, x, which actually equals 11.
⇒ 20% × x = 11
⇒ (20/100) × x = 11
⇒ 0.2 × x = 11
⇒ x = 11/0.2
⇒ x = 55
Hence the number of cookies Charlie baked is 55, if he ate 20% of the cookies which equals 11.
