Answer:

The new principal after the first payment is $ 1,380.65

Step-by-step explanation:

1. We calculate the amount of interest to pay in the first payment, this way:

Interest = Amount of loan * (interest rate/months in a year)

Replacing with the real values we know:

Interest = 1,500 * (0.1/12)

Interest = 1500 * 0.0083 = $ 12.50

2. Now we subtract the Interest from the monthly payment, as follows:

Payment to principal = 131.85 - 12.50

Payment to principal = $ 119.35

3. Finally we subtract that 1st payment to principal from the initial principal to get the new principal, this way:

New Principal = 1,500 - 119.35

New Principal = $ 1,380.65

The new principal after the first payment is $ 1,380.65

Answer: r = 12.1cm, d = 24.2cm, Area = 460.0cm²

Step-by-step explanation:

From the formula,

Circumference of a circle = πd or 2πr.

To find the radius, we have to equate 76 cm to πd or 2πr and make r or d the subject of the formula. Now

76 = 2πr, don't forget that

π = 22/7 or 3.142

Now make r the subject of the formula

r = 76/2π

= 76/2 x 3.142

= 76/6.284

= 12.1 cm

d = 2r

= 2 x 12.1

= 24.2cm.

Area of the circle is πr²

= 3.142 x (12.1)²

= 3.142 x 146.41

= 460.0 cm²

Answer:

volume is 432 cubic inches

Step-by-step explanation:

A box measures 1 ft. long, 1/2 ftwide, and  1/2 ft high.

we need to find the volume of the box

Volume of the box formula is

[tex]volume = length \cdot width \cdot height\\[/tex]

convert all the measurement into inches

1 feet = 12 inches

1/2 feet = 6 inches

length = 12 inches, width = 6 inches , height = 6 inches

now we plug in the values in volume

[tex]volume = 12 \cdot 6 \cdot 6= 432 in^3[/tex]

Answer:

exact form is 5/12

decimal form is 0.416666

Step-by-step explanation:

Equivalent fractions are fractions that have the same value or proportion. To find an equivalent fraction to a given fraction, you multiply or divide both the numerator and the denominator by the same number. Therefore, 10/24 and 15/36 are equivalent fractions to 5/12.

To find an equivalent fraction to 5/12, you simply multiply or divide both the numerator (the top number) and the denominator (the bottom number) by the same non-zero number. An equivalent fraction will have a different numerator and denominator, but it will represent the same value or proportion. For example, if we multiply both the numerator and the denominator of 5/12 by 2, we get 10/24. Therefore, 10/24 is an equivalent fraction to 5/12.

Similarly, if we multiply 5 (the numerator) and 12 (the denominator) by 3, we get the equivalent fraction 15/36.

So, 5/12 = 10/24 = 15/36 in terms of value or proportion.

The total length of the three longest bulletin boards when placed side by side would be 180 inches.

To calculate the total length of the three longest bulletin boards when placed side by side, we first need to determine the average length of a bulletin board and then multiply it by three.

The length of bulletin boards can vary widely depending on their purpose, but let's assume a standard size commonly found in schools or offices.

A typical bulletin board might measure around 4 feet (48 inches) in length.

However, some bulletin boards can be longer, reaching up to 6 or 8 feet.

Let's take a conservative estimate of 5 feet (60 inches) for our calculations.

So, if we have three bulletin boards each measuring 5 feet (60 inches) in length, the total length when placed side by side would be:

Total length = Length of one bulletin board × Number of bulletin boards

Total length = 60 inches × 3

Total length = 180 inches

Therefore, the total length of the three longest bulletin boards when placed side by side would be 180 inches.

To simplify a fraction by division you must have common factors between the denominator and the neominator to divide (or cancel) them

Multiply the top equation by 6 and and the bottom equation by –5 and then add the equations is the correct answer.

Solution:

Given system of equations:

8x + 5y = –7 – – – – (1)

–7x + 6y = –4 – – – – (2)

Multiply top equation by 6 and and bottom equation by –5

(1) × 6 ⇒ 48x + 30y = –42

(2) × –5 ⇒ 35x – 30y = 20

Now add these two equations, we get

(48x + 30y) + (35x – 30y) = –42 + 20

48x + 35x + 30y  – 30y = –42 + 20

83x = –20

The variable y is eliminated.

Therefore Multiply the top equation by 6 and and the bottom equation by –5 and then add the equations is the correct answer.

Answer:

Multiply the top equation by −5, then add the equations.

Answer:

Step-by-step explanation:

The line is in slope-intercept form which looks like y = mx + b.

"x" and "y" represent points on the line.

"m" is the slope (how steep the line is) and if the line goes up (+) or down (-).

"b" is the y-intercept, which is where the graph hits the y-axis.

Take information from the equation y=-2x+6. Use the slope and the y-intercept to graph to line.

m = -2  =  [tex]-\frac{2}{1}[/tex]   (Fraction form).

b = 6

Plot a point at the y-intercept on the y-axis

If the y-intercept is 6, so you plot the point at (0, 6). (The y-intercept occurs when x = 0).

Find another point

Count the number of rise and run from the y-intercept.

Remember the slope is [tex]\frac{rise}{run}[/tex]

Run is the number of squares moving right. Rise is the number of squares moving up (if positive) or down (if negative).

Since the slope is -2/1, move two squares down and one square to the right to find another point on the line.

Connect the points

You only need two points to make a line. If you want the line to be longer, you can extend it with a ruler.

Other formatting rules

Remember to add arrows at the ends of the x and y axis.

Also, add arrows to the ends of the the line that you graphed.

Most teachers ask you to label the line with the equation.

Answer: 1.9

Step-by-step explanation:

because you keep adding 1.9 to get your result

Answer:

11.1

Step-by-step explanation:

3.9 - 1.5 = 2.4

if you add 2.4 to one of the numbers in the sequence it will be the next number.

1.5 + 2.4 = 3.9

3.9 + 2.4 = 6.3

6.3 + 2.4 = 8.7

if this is the case then 8.7 + 2.4 = 11.1

Answer:

F(3) = 2 * 3 - 1, which is 6 - 1 equaling 5.

Step-by-step explanation:

3 times 2 is six since you have to follow PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction). Multiplication is before Subtraction, and that is why we multiply 2 and 3 first, since 3 replaces the variable x. After multiplying 2 and 3 to get 6, subtract by 1 to get 5.

Tom read a total of 11/12 of the two books combined by reading 1/2 of the first book and 5/12 of the second book, after finding a common denominator to add the fractions.

To calculate the total fraction of the two books that Tom has read, we need to add the fractions of each book he has read together. Tom read 1/2 of the first book and 5/12 of the second book.

To add these fractions, they need to have a common denominator. The lowest common denominator between 2 and 12 is 12.

Therefore, we convert 1/2 into 6/12 so that both fractions have the same denominator.

Now, the fractions to be added are 6/12 (from the first book) and 5/12 (from the second book).

Adding these fractions, we get:

6/12 + 5/12 = 11/12

So, Tom has read a total of 11/12 of the two books combined. This method of finding a common denominator and then adding the numerators is an effective strategy to add fractions with different denominators, providing a clear, step-by-step approach to solving such problems in mathematics.

Option B: 5.25 is the length of XZ

Explanation:

The triangles PQR and XYZ are similar.

To determine the length of XZ, let us use the similarity theorem.

The theorem states that, "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".

Thus,

[tex]\frac{QR}{YZ} =\frac{PR}{XZ}[/tex]

Let us substitute the values from the diagram, we have,

[tex]\frac{4}{3} =\frac{7}{XZ}[/tex]

Multiplying both sides by 3, we get,

[tex]4 =\frac{21}{XZ}[/tex]

Thus,

[tex]XZ =\frac{21}{4}=5.25[/tex]

Thus, the length of XZ is 5.25

Hence, Option B is the correct answer.

i.e. [tex]ES=FS=GS\\ES^2 =FS^2 =GS^2[/tex]

[tex](x-2)^2+(y-6)^2 =(x-2)^2+(y-4)^2 =(x-6)^2+(y-4)^2 \\i.e. x^2-4x+4+y^2-12y+36 = x^2-4x+4+y^2-8y+16 = x^2-12x+36+y^2-8y+16 \\4y = 20: y =5\\8x=32\\x=4[/tex]

Thus circumcenter is (4,5)
