Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

The answer is 8 so its a direct proportion
I think...
The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

The total cost (c) is going to be of the 4 notebooks together
We don't know how many notebooks Greg got, so it's represented by n.
It doesn't matter how many notebooks Greg purchased, because each of them were $4.
So to represent the total cost of the notebooks, you would write c = 4n

Given the quantity of 3 x squared plus x minus 4, all over x minus 1, what are the domain and range?
Answers
Answer:
4th answer option
Step-by-step explanation:
the domain is easy : x must not be 1 to avoid 0 in the denominator (and hence a .../0 expression).
that eliminates the 1st and 3rd answer.
for the range :
x = 0 gives us y = -4/-1 = 4
x = 2 gives us y = 10/1 = 10
so, it is very likely that limit for y = 7 for x = 1, which is then the impossible y-value in the range for the impossible x- value.
let's verify with
l'Hopital's Rule
If lim x→a f(x) = 0
and
lim x→a g(x) = 0
then
lim x→a f(x)/g(x) = lim x→a f'(x)/g'(x)
f = 3x² + x - 4
f' = 6x + 1
g = x - 1
g' = 1
f'(x)/g'(x) = (6x + 1)/1 = 6x + 1
for a = 1, therefore x = 1
6×1 + 1 = 7
so, yes, as the limit for x = 1 is y = 7, for the invalid domain value x = 1, the invalid range value is y = 7.

Answer:

Step-by-step explanation:
You add the 11x and 58
Answer: hope this helps ♡ (i wont mind getting brainliest )
x = 3
Step-by-step explanation:
z° and 89° are two opposite angles.
z° = 89°
89° + 89° + (11x + 58)° + (11x + 58)° = 360° (adds up to 360° coz its a circle)
178° + (11x + 58)° + (11x + 58)° = 360°
178° + 58° + 58° + (11x + 11x)° = 360°
178° + 116° + 22x° = 360°
294° + 22x° = 360°
294° - 294° + 22x° = 360° - 294°
22x = 66
22x ÷ 22 = 66 ÷ 22
x = 3
(double check: 11×3 = 33 2×(33+58)+178=360° ✓)
Use the distributive property to write an expression that is equivalent to 10a - 15b + 25 in factored form.
Answers
Using the distributive property:
10a - 15b + 25
(10a - 10b) - 5b + 25
10(a - b) - 5b + 25
(10(a - b) - 5)b + 25
((10a - 10b) - 5)b + 25
(Factored form)
10a - 15b + 25 —> 5(2a - 3b) + 25
Hence, the distributed expression would be:

Answers
Answer:
1 1/5.
Step-by-step explanation:
To divide a fraction by another fraction you have to change the equation like "Keep, Switch, Flip".
For the problem 24/25 ÷ 4/5,
You KEEP the first fraction as is, so 24/25
Then, you SWITCH the sign from division to multiplication.
Finally, you FLIP the second fraction upside down, (the reciprocal). So it's 5/4.
The equation is now 24/25 * 5/4, which we can just multiply the numerators and denominators. (or cross cancel first)
24 * 5 = 120
25 * 4 = 100
the fraction is 120/100. Simplified, it can be divided by 10 to make 12/10, and finally divided by 2 to make 6/5, or 1 1/5.
