The monthly payment for a one-year loan = $1,081.00

The higher the period of time, the lesser the monthly payment of a loan.

Claire needs to borrow $12,000 from a local bank with an interest of 8.1% which is,

8.1/100 × $12,000 =$972

This means after one year she will pay back;

$12,000 + $972 = $12,972

Therefore, monthly payment for a year loan = 12972/12

= $1,081.00

Step-by-step explanation:

Moving to the left of the number line means that the numbers are getting smaller, so with the example of

x < 3.5, x can be 3.4, 3.3, 3.2 and so on

Moving to the right of the number line means that the numbers are getting bigger, for example x > -1.5, x can be -1.4, -1.3, -1.2, -1.1, 0, 0.1, 0.2 and so on

x < 3.5 means that a number (x) is less than 3.5, so it's a hollow circle at 3.5 with the arrow to the left

x > -1.5 means that a number (x) is greater than -1.5, we cannot go the left of the number line as it will mean x is less than (<) -1.5, so it's a hollow circle at 1.5 with the arrow to the right

x ≥ -9/2 can be written as x ≥ -4.5 which means that a number (x) is greater than or equal to -4.5. It's a filled circle because you include -4.5 with the arrow to the right.

x ≤ 7/4 can be written as x ≤ 1.75 which means that a number (x) is less than or equal to 1.75, so it's a filled circle at 1.75 with the arrow to the left

Answer:

3 ( 5a - 2b + 12)

Step-by-step explanation:

15 = 3 * 5

6 = 2 * 3

36 = 2 * 2 * 3 * 3

GCF = 3

15a - 6b + 36 = (3* 5 * a) - (3 *2 * b) + (3 * 12)

                    = 3 ( 5a - 2b + 12)

Answer:

X = S-R

Step-by-step explanation:

I don't really know what it means, maybe what makes sense is X = S-R?

Answer:

X = S-R

Step-by-step explanation:

We need to change the equation so that it shows X = .....

Thus, we move R to the opposite side of the equation, and we get...

X = S-R

(Since Positive R becomes negative after swapping sides)

Easy The easiest way Is to Find out what 36X3 is off the top of my head it is 108. Finally Break apart 108 into 100 and 8. since the fraction is 108;4 you need to find out how many times 4 goes into 100. which is easy 25. now what is 8 /4 answer is 2, Ad them together to get the answer is 27. This is probably the easiest method if it ends in a whole number

Step-by-step explanation:

Answer:

27

Step-by-step explanation:

First split the equation.

=> 36 x 3/4

=> 36 x 1/4 x 3

We know 36/4 = 9

=> 9 x 3

=> 27

Answer:

1)An angle bisector is basically the division of an angle into two equal parts, so you should just draw a line in the middle after you found the angles using the compass

2) parallel lines is a pair of lines that never intersect, and are always the same distance apart. you should use the compass to draw a 90-degree angle at the end of the line XY, and use the straightedge to draw a line that is parallel to the line XY.

Answer:

see attached diagram

Step-by-step explanation:

Angle Bisector

The angle bisector bisects the angle into two equal angles.

Measure the angle EDF (I've measured this as 115°)

Divide this by 2:  115 ÷ 2 = 57.5°

Measure an angle of 57.5° from point D on the line DF and draw a line.

Parallel lines

Measure two lines of equal length from points X and Y at an angle of 90° to the line XY.  Join the points for the parallel line.

The angle bisector and parallel line are shown in red on the attached diagram.

[tex]sin(G)=0.91[/tex]

Step-by-step explanation:

Recall that [tex]sin(\theta)=\frac{opposite}{hypotenuse}[/tex] with respect to the angle [tex]\theta[/tex] for a right triangle. Since we are given our hypotenuse of [tex]\sqrt{85}[/tex] and our adjacent side of [tex]\sqrt{15}[/tex], we can use the Pythagorean Theorem to solve for the missing opposite side:

[tex]a^2+b^2=c^2\\\\(opposite)^2+(adjacent)^2=(hypotenuse)^2\\\\(opposite)^2+(\sqrt{15})^2=(\sqrt{85})^2\\\\(opposite)^2+15=85\\\\(opposite)^2=70\\\\opposite=\sqrt{70}[/tex]

Thus, [tex]sin(G)=\frac{\sqrt{70}}{\sqrt{85}}\approx0.91[/tex]

Answer:

∠ ACD = 130°

Step-by-step explanation:

∠ ABC = 180° - 120° = 60° ( adjacent angles on a straight line )

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ACD is an exterior angle of the triangle , then

∠ ACD = 70° + 60° = 130°

Step-by-step explanation:

number explanation

1. 20 + 4x = 16

  -20           -20

2. 4x = -4

    4       4

3. -4 divided by 4 = -1

word explanation

1.rewrite the problem

2. subtract 20 from 20 and subtract 20 from 16

all of the numbers subtract 20 except the number with the variable

3. 20 - 20 = 0

16 - 20 = -4 because you take the sign of the bigger number

4. you bring down 4x divided by 4 it gets crossed out then you do -4 divided by 4 and your answer is

negative 1

-1
