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?
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
Which of the following systems of equations has the solution (1,2)?
A. y−x=1
3y−4x=10
B. 3y−x=1
8y−2x=4
C. 3y+2x=8
4y−x=7
D. −2y+5x=−1
2y+2x=6
Answer:
C
Step-by-step explanation:
Plug in 1 for x and 2 for y in each equation. Your answer is the one where both equations are true.
3(2) + 2(1) = 8
6 + 2 = 8
8 = 8
4(2) - 1 = 7
8 - 1 = 7
7 = 7
Write a quadratic equation to represent the situation. Solve the equation by factoring. Use the table and graphing method to check. NEED QUADRATIC EQUATION! A rectangular poster has an area of 190 square inches. The height of the poster is 1 inch less than twice its width. Find the dimensions of the poster.
Answer:
L * W = area
L * W = 190
L + 1 = 2W
Therefore, L = 2W - 1
The easiest way to do this is to find the factors, and then see what fits.
Step-by-step explanation:
Factors of 190 = {190,1}, {95,2}, {5,38}, {19,10}
In which of these pairs is one number "twice as much less one" than the other?
The solution is 19,10. 19*10 = 190 square feet. The length (19) is twice the width (10) minus one.

Answer:
The best option is:
(a) I and II only
Step-by-step explanation:
Each kind of bond has a face value, usually known as par value. If a bond sells above the par value, it is a premium bond, if it sells below the par value, it is a discount bond. Hence first statement is true.
If a bond has a selling rate of 100, it means it is selling at its par value. For example if a bond has a par value of $100, then a selling rate of 100 means it sells at 100$, a selling rate of 90 means it sell at 90$, a selling rate of 120 means it sells at $120. For a premium bond, the selling rate is always above 100. Hence second statement is true.
Premium bonds are mostly sold by corporations, but alot of scheme of trading premium bonds have also been introduced by governments all around the world. We can say that the statement can be true for some specific country, but globally speaking, the statement is false.

67 2 3 % of the animals at an animal shelter are dogs. About what fraction of the animals at the shelter are dogs?
Answer:
About 2/3 of the animals at the shelter are dogs
Step-by-step explanation:
Let's first transform the mixed number to the corresponding improper fraction.
67 2/3 is equivalent to (3*67 + 2)/3 = 203/3
we are asked to find a fraction equivalent to 203/3%. To do this, we have to divide the fraction by 10, as follows:
203/3% = (203/3)*(1/100) = 203/300 ≈ 2/3

Which figure has exactly one line of symmetry? A rhombus, pentagon, rectangle and triangle are shown. A. Rhombus B. Pentagon C. Rectangle D. Triangle
Answer: The figure that has exactly one line of symmetry is B. Pentagon.
Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.
Using either method, we can see that:
A. Rhombus has two lines of symmetry: one diagonal and one vertical.
C. Rectangle has two lines of symmetry: one horizontal and one vertical.
D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.
B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.
Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.
Hope this helps, and have a great day! =)

Answer:
155α+81
Step-by-step explanation:
There are two rectangles:
1
area₁ =- (15α+8)(7) = 15α*7 + 8*7 = 105α+56
2
area₂ = (10α+5)(12-7) = (10α+5)(5) = 10α*5 + 5*5 = 50a + 25
Total area = area₁ + area₂
Total area = (105α+56)+(50α+25)
Total area = 105α + 50α + 56 + 25
Total area = 155α + 81

Step-by-step explanation:
a rectangular field has side lengths that measure 9/10 mile and 1/2 mile what is the area of the field
Answer:
\(\frac{9}{20}miles^2=0.45miles^2\)
Step-by-step explanation:
To find the area of a rectangle:
\(a=l*w\)
where \(l\) is the length and \(w\) is the width.
In this case:
length: \(l=\frac{9}{10}miles\)
width: \(w=\frac{1}{2} miles\)
thus, we multiply this quantities to find the area:
\(a=(\frac{9}{10} miles)(\frac{1}{2}miles )\\\\a=\frac{9*1}{10*2}miles^2\\ \\a=\frac{9}{20}miles^2\)
the area of this rectangle is 9/20 miles squared, or what is the same 0.45 miles squared
Triangle UVW is drawn with vertices at U(−1, 1), V(0, −4), W(−4, −1). Determine the coordinates of the vertices for the image, triangle U′V′W′, if the preimage is rotated 90° counterclockwise.
U′(1, −1), V′(0, 4), W′(4, 1)
U′(−1, −1), V′(4, 0), W′(1, −4)
U′(−1, 1), V′(4, 0), W′(1, 4)
U′(−1, 1), V′(0, −4), W′(−4, −1)
The correct answer is U′(1, −1), V′(4, 0), W′(1, 4). When a point is rotated 90° counterclockwise about the origin, the x-coordinate and y-coordinate change places, and the sign of the new x-coordinate is the opposite of the original y-coordinate. So for example, point U(−1, 1) becomes U′(1, −1).
