Someone invested some money at 8% and $300 more than
twice this amount at 12%. Her total annual income from
the two investments is $548. How much is invested at
each rate?
32
Answer:
$1600 at 8% and 3500 at 12%
Step-by-step explanation:
The rule of the interest is I = PRT, where
P is the amount of investment R is the rate in decimalT is the timeAssume that the amount of money is $x
∴ P = x
∵ The rate is 8%
∴ R = 8/100 = 0.08
∵ She has an annual income
∴ T = 1
→ Substitute them in the rule to find the interest amount
∴ I = x × 0.08 × 1
∴ I = 0.08x
∵ She invested $300 more than twice the previous amount
∴ P = 2x + 300
∵ The rate is 12%
∴ R = 12/100 = 0.12
∵ T = 1
→ Substitute them in the rule to find the other interest amount
∴ I = (2x + 300) × 0.12 × 1
∴ I = 0.24x + 36
∵ Her total annual income from both investments is $548
→ Add the two amount of interest and equate their sum by 548
∴ 0.08x + 0.24x + 36 = 548
→ Add the like terms in the left side
∴ 0.32x + 36 = 548
→ Subtract 36 from both sides
∴ 0.32x + 36 - 36 = 548 - 36
∴ 0.32x = 512
→ Divide both sides by 0.32
∴ x = 1600
∴ She invested $1600 at 8%
→ Substitute x by 1600 in the expression of the other amount to find it
∵ 2x + 300 = 2(1600) + 300 = 3500
∴ She invested $3500 at 12%
Two fitness clubs are asding new members. Fitness club A cutrently has 450 memebers and adds 15 nee memeners each month. Fitness club B currently has 400 members amd adds 25 new members each month. After how many months will fitness club A and B have the samr number of members?
Answer:
It will take 5 months for the two fitness clubs to have the same number of members
Step-by-step explanation:
Let the number of months it takes fitness club A and B to have the same number be = x
For the two clubs to have the same number in x months, that means we can set up an equation as follows
450 +15x = 400 + 25x
Grouping like terms
450 - 400 = 25x -15x
50 = 10x
x= 5
Therefore, it will take 5 months for the two fitness clubs to have the same number of members

Which set of numbers are integers but not whole numbers or natural numbers?
PLEASE HURRYYYYY!!!!!
Integers, whole numbers and natural numbers are numbers without decimal points.
The set of number that are integer but not whole or natural number is:
[tex]\{-2, -3, -4\}[/tex]
As stated above that three set of numbers do not contain decimal point;
However, the difference between them is that; a negative number without a decimal point is referred to as an integer
From the given set: only [tex]\{-2, -3, -4\}[/tex] fit into the description of an integer, because

Hi! Could someone please answer this question I’m stuck on it please do it ASAP! id appreciate it
Answer:
198.57 cm^2
Step-by-step explanation:
If we join the 2 semi circles, we get a circle.
We can A = pi*r^2
d= 10, r = 5
Area of circle = pi*5^2 ,
= 25*pi
Since diameter= 10 vertically, it should be 10 horizontally too, but it's divided into 2 because of the 2 semi circles.
Thus, width of each semi circle is 5 cm.
Area of rectangle = l *b
Area = (22-10)*10
Area = 12*10
= 120 cm ^2
Total area = 25pi + 120
= 120 + 25(22/7)
= 120 + 78.57
= 198.57

PLEASE ! Find the slope of the line graphed.
Answer:
slope = -1/2
Step-by-step explanation:
From the graph, pick two points:
[tex](x_{1} , y_{1} ) (x_{2} , y_{2} )[/tex]-> (0, -2) and (-4, 0)
Slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
so (-2 - 0)/(0-(-4)) = -2/4 -> -1/2

Jeremy stands on the edge of a river and throws a rock into the water. The rock leaves his hand at a height 4 feet above the water. The rock reaches the highest point along its path when it is a horizontal distance of 28 feet from his hand and 17 feet above the water. Write a function to represent the height of the rock in terms of its distance from Jeremy’s hand.
Answer:
The height, h, of the rock as a function of the horizontal distance from Jeremy's hand is h = -13/784·(x - 28)² + 17
Step-by-step explanation:
The given parameters are;
The height of the rock above the water when it leaves Jeremy's hand = feet
The maximum height of the rock = 28 feet
The horizontal distance at maximum height = 17 feet
Therefore, the given coordinates of the maximum height = (28, 17)
The equation of a parabola in vertex form is f(x) = a(x - h)² + k
Taking the maximum point as the vertex of the parabola, we have;
(h, k) = (28, 17)
Substituting the values gives;
f(x) = a·(x - 28)² + 17
At x = 0, the height = 4, we have;
f(0) = 4 = a·(0 - 28)² + 17
4 - 17 = a×28²
-13 = 784 × a
a = -13/784
Therefore, the height of the rock, f(x) = h, as a function of the horizontal distance from Jeremy's hand is therefore;
f(x) = h = -13/784·(x - 28)² + 17
