Alyssa invested a total of $1500 in two accounts. One account paid 2% annual interest, and the other account paid 4% annual interest. After one year, Alyssa earned a total of $44 interest. How much did she invest in each account? $# in 2% account, $# in 4% account
Answer:
700$ at 2% 800$ at 4%
Step-by-step explanation:
x+y=1500 This is because the total is 1500 dollars into 2 different accounts, x and y.
0.02x+0.04y=44 This is because it says 2 percent interest in one account and 4 percent in the other, and the totals add up to 44 dollars.
Now use elimination method.
x+y=1500(-0.02)=-0.02x+-0.02y=-30
0.02x+0.04y=44
Now you end up with 0.02y=14, solve for y and you get 700. That's the value of y which now you can then subtract from 1500 and get 800 which is the value of x.

Decide whether ABCD with vertices A (3,8) B (6,5) C (5,4) , and D (2,7) is a rectangle a rhombus or a square
Given:
The vertices of the quadrilateral ABCD are A(3,8), B(6,5), C(5,4), and D(2,7).
To find:
Whether the given quadrilateral is a rectangle, a rhombus or a square.
Solution:
Distance formula: The distance between two points is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, the side lengths are:
[tex]AB=\sqrt{\left(6-3\right)^2+\left(5-8\right)^2}[/tex]
[tex]AB=\sqrt{\left(3\right)^2+\left(-3\right)^2}[/tex]
[tex]AB=\sqrt{9+9}[/tex]
[tex]AB=\sqrt{18}[/tex]
[tex]AB=3\sqrt{2}[/tex]
Similarly,
[tex]BC=\sqrt{\left(5-6\right)^2+\left(4-5\right)^2}=\sqrt{2}[/tex]
[tex]CD=\sqrt{\left(2-5\right)^2+\left(7-4\right)^2}=3\sqrt{2}[/tex]
[tex]AD=\sqrt{\left(2-3\right)^2+\left(7-8\right)^2}=\sqrt{2}[/tex]
The length of diagonals are:
[tex]AC=\sqrt{\left(5-3\right)^2+\left(4-8\right)^2}=2\sqrt{5}[/tex]
[tex]BD=\sqrt{\left(2-6\right)^2+\left(7-5\right)^2}=2\sqrt{5}[/tex]
From the above calculation, we conclude that the given quadrilateral has two pairs of congruent opposite sides and equal diagonals.
Opposite sides of a rectangle are equal and its diagonals are also equal.
Therefore, the given quadrilateral ABCD is a rectangle.

how many toothpicks are needed to build the tree on day 100?
Answer:
100 x 4 = 400 - 91 = 309
Step-by-step explanation:
Answer:
100= 4 + 3 (100-1)
4+3 (99)
4 + 297 is 301
Step-by-step explanation:
The first row starts with 4 toothpicks, and they increase by +3 in each row. The first tree is already accounted for which makes the 4 + 3, and why I have 100-1. The teacher said the answer was correct but I doubted the equation. Can you tell me if this is correct?

PLEASE HELP! a. How many 7-digit numbers have odd numbers in the odd positions (i.e. odd numbers in the first, third, fifth and seventh positions)?
(2)
b. How many of these have even numbers in the even positions?
Answer:
a) 625,000
b) 78,125 if 0 is counted as even or 40,000 if it is not.
Step-by-step explanation:
Represent the 7 digit number by abcdefg
Position Allowable digits Number of allowable digits
g 1,3,5,7,9 5
f 0,1,2,3,4,5,6,7,8,9 10
e 1,3,5,7,9 5
d 0,1,2,3,4,5,6,7,8,9 10
c 1,3,5,7,9 5
b 0,1,2,3,4,5,6,7,8,9 10
a 1,3,5,7,9 5
This implies that the number of 7 digit numbers with odd digits in the odd positions is
5x10x5x10x5x10x5=625000
For part b, count 0 as an even digit. Then rule out 1,3,5,7,9 in positions b, d, and f. This leaves 5 possible digits in all 7 locations. So the answer is
5^7=78,125
If 0 is not counted as an even digit, then the answer is
4^3+5^4=40000

A company makes 110 bags.
46 of the bags have buttons but no zips.
20 of the bags have zips but no buttons.
39 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?
Answer:
51/110
Step-by-step explanation:
No: of bags with buttons but no zips = 46
No: of bags that have both buttons and zipz = 110-(46+20+39) = 5
No: of bags with buttons = 46+ 5 = 51
Total no: of bags = 110
Probabilty = 51/110

Calculate the monthly payment for a $14,790 auto loan over four years at 6.9% annual interest.
Use the formula,
P=A(rn)(1+rn)nt(1+rn)nt1
where A is the amount to finance, r is the annual interest rate, n is the number of times interest is compounded in one year, and t is the number of years.
Answer:
352.05
Step-by-step explanation:
I don't know how to interpret the equation you wrote and so I just used annuities
I have attached my work below
the monthly payment for a $14,790 auto loan over four years at 6.9% annual interest is $353.95.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, a $14,790 auto loan over four years at 6.9% annual interest.
To calculate the monthly payment for a $14,790 auto loan over four years at 6.9% annual interest,
we can use the formula for the monthly payment of a loan:
M = P * (r/12) * (1 + r/12)ⁿ / ((1 + r/12)ⁿ¹)
where:
M = monthly payment
P = principal amount (loan amount)
r = annual interest rate (as a decimal)
n = total number of payments (number of years * 12)
Plugging in the given values, we get:
P = $14,790
r = 0.069 (6.9% expressed as a decimal)
n = 4 * 12 = 48 (4 years with 12 payments per year)
M = $14,790 * (0.069/12) * (1 + 0.069/12)⁴⁸ / ((1 + 0.069/12)⁴⁸⁻¹)
M = $353.95
Therefore, the monthly payment for a $14,790 auto loan over four years at 6.9% annual interest is $353.95.

Prompt: Describe the similarities and differences of the properties of squares, rectangles, rhombi, and parallelograms.
Answer:
Here are the properties of the rhombus, rectangle, and square. Note that because these three quadrilaterals are all parallelograms, their properties include the parallelogram properties.
The rhombus has the following properties:
All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary).
All sides are congruent by definition.
The diagonals bisect the angles.
The diagonals are perpendicular bisectors of each other.
The rectangle has the following properties:
All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other).
All angles are right angles by definition.
The diagonals are congruent.
The square has the following properties:
All the properties of a rhombus apply (the ones that matter here are parallel sides, diagonals are perpendicular bisectors of each other, and diagonals bisect the angles).
All the properties of a rectangle apply (the only one that matters here is diagonals are congruent).
All sides are congruent by definition.
All angles are right angles by definition.
