Answer:
The formula for an exponential decay problem is: y = x (1 - r)^x
Where x = initial amount, r = rate of decay and x = # time periods
So, x = $258, r = 8% = .08 and x = 11 years
y = 258 (1 - 0.08)^11 = 258 (0.92)^11 = 258 * 0.3996 = $103.10

In △ABC, G is the centroid and BE = 21. Find BG and GE.
Answers
Answer:
BG = 7, GE = 14Step-by-step explanation:
The centroid is the intercession of medians.
The centroid theorem states that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.
BE is the median and point G is 2/3 of the distance from E:
GE = 2/3BE = 2/3(21) = 14Then BG is:
BG = BE - GE = 21 - 14 = 7The answer is BG = 7, GE = 14
Answer:
the answer is BG=7,GE=14

You pick a card at random. 4 5 6 7 What is P(less than 7)? Write your answer as a fraction or whole number.
Answers
Answer:
3/4 is less than 7.
Step-by-step explanation:
There are 4 numbers but there are only 3 less than 7.
The probability P(less than 7) is 3/4.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
For the given situation,
The cards are numbered as s = {4,5,6,7}
⇒[tex]n(s)=4[/tex]
The event is probability of picking the cards less than 7
Cards less than [tex]7[/tex] , [tex]e=4,5,6[/tex]
⇒[tex]n(e)=3[/tex]
Probability of picking the card is given by [tex]p(e)=\frac{n(e)}{n(s)}[/tex]
On substituting the values,
⇒[tex]p(less than 7)=\frac{3}{4}[/tex]
Thus the probability P(less than 7) is 3/4.

Find the solution to the system of equations given below:
x=-4
-5x-4y=16
PLS HELP
Answers
Answer:
Step-by-step explanation:
Since x=-4 plug in the -4 into the equation to find y,
-5(-4)-4y=16
20-4y=16 -20 -20 __________
-4y=-4
-4y/-4=-4/-4
___________
y=1
So now you found both x and y so plug in both now to check if both are correct.
-5(-4)-4(1)=16
20-4=16
16=16
So both y and x are correct.

For the line above, what is the slope? *
Answers
Answer: The slope is 2.
Step-by-step explanation:
To get the slope, use this tip: Rise over run
Count how much it rises, which is 4, and how much it "runs' which is 2. Now put rise above run which is 4/2. This simplifies to simply 2.
Answer:
The slope is 2.
Step-by-step explanation:
The points on the line are (1, -2) which can be labeled as x1 and y1, and the other is (3,2) which can be labeled as x2 and y2. you set up the equation in the slope formula, so 2 - - 2 / 3 - 1. Since there are two negatives, the subtraction signs turn into addition signs, and you get 4/2, which simplyfied is 2. Hope this helps :)

If the sin 30º = 1/2
then which statement is true? (6 points)
a. cos 150° = 0, because the cosine and sine are supplements
b. cos 60° = 0, because the cosine and sine are complements
c. cos 150° = 1, because the cosine and sine are supplements
d. cos 60° = 1/2, because the cosine and sine are complements
Answers
Because sine and cosine are complements, we will have that:
cos(60°) = 1/2.
Which statement is true?First, because cosine and sine are complements, we know that:
cos(x) = sin(x + 90°).
cos(90° - x) = sin(x).
We will use the second relation, with x = 30° we can write:
cos(90° - 30°) = sin(30°)
cos(60°) = sin(30°)
And we know that sin(30°) = 1/2
Then we also have cos(60°) = 1/2.
So the correct option is d.

5 subtracted from 3 times a number x gives 7.
Answers
Answer:
3x-5=7
3x=7+5
x=12/3
x = 4
Answer:
Step-by-step explanation:
3 times a number x: 3*x = 3x
5 subtracted from 3x = 3x - 5
Equation: 3x - 5 = 7
Solution:
Add 5 to both sides
3x - 5 + 5 = 7 + 5
3x = 12
Divide both sides by 3
3x/3 = 12/3
x = 4

What is the measure of angle W?
25°
65°
1150
120°
Answers
Answer:
115 degrees
Step-by-step explanation:
We know that angle y is 45 degrees and angle z is 70 degrees so to find x, you do 180-45-70 to get 65 degrees.
Because W plus X has to equal 180 degrees, 180-65=115, so the answer is 115 degrees
Answer:
choice 3) W = 115 degrees
Step-by-step explanation:
all triangle interior angles add up to 180 degrees
180 = 45 + 70 + X
X = 65 degrees
Angle W is supplemental to angle X (angle W and angle X add up to 180 degrees.)
W = 180 - 65 = 115 degrees
