A couple realizes a real estate financing of R $ 180,000.00, to be paid in 360 monthly installments, with an effective interest

rate of 1% per month. The first installment is paid one month after the funds are released and the monthly installment is R $ 500.00 plus 1% interest on the outstanding balance (amount due before payment). Note that, with each payment, the outstanding balance is reduced by R $ 500.00 and consider that there is no arrears. By making the payment in this way, the amount, in reais, to be paid to the bank in the tenth installment is
a) 2,075.00.
b) 2,093.00.
c) 2,138.00.
d) 2 255.00.

Answer:

ANSWER: letter D

Step-by-step explanation:

In the tenth installment, the debit balance is, in reais, of

180000 - 9. 500 = 175500

The 1% interest on this amount results in:

1% . 175 500 = 1755

Thus, the tenth installment is, in reais, 500 + 1755 = 2255

∠ABD is formed by a tangent and a secant intersecting outside of a circle. If minor arc AC = 72° and minor arc CD = 132°, what i
Kruka [31]

Answer:

measure of ∠ABD = 42°

Step-by-step explanation:

Angle Formed by Tangent and Secant = (1/2)*(difference of Intercepted Arcs)

In this case the intercepted arcs are: minor arc AC and minor arc AD. Let´s first find minor arc AD, we know that:

minor arc AC + minor arc CD + minor arc AD = 360°

Then,

minor arc AD = 360° - minor arc AC - minor arc CD

minor arc AD = 360° - 72° - 132°

minor arc AD = 156°

Replacing in the aforementioned formula:

Angle Formed by Tangent and Secant = (1/2)*(difference of Intercepted Arcs)

∠ABD = (1/2)*(minor arc AD - minor arc AC)

∠ABD = (1/2)*(156° - 72°)

∠ABD = 42°

Through (0,2) and (4,1) write the slope intercept form of the equation of the line
lesya692 [45]

Answer:

y= -1/4x+2

Step-by-step explanation:

use the slope formula to get the slope: y2-y1/x2-x1 or 1-2/4-0 subtract to get -1/4 that is the m(slope)*x in y=mx+b now for b it is the point in which x=0 so the first point has x=0 and it's y is 2 so b is 2. put it together to get y=-1/4x+2

Compare and contrast the perpendicular bisectors and angle bisectors of a triangle. How are they alike? How are they different?
AleksandrR [38]

<span>1 perpendicular bisector divides 1 side of the triangle into two equal lengths at a 90 degree angle. So if there's is three perpendicular bisectors, then it splits all three sides the triangles into equal lengths.

Angle bisectors splits an angle of a triangle into two even degrees.  
 </span>

<span>
</span>

<span>EX: if it is an equilateral triangle, each angle will be sixty degrees. Therefore, ONE angle bisector will split ONE of the angles into even degrees of thirty degrees. </span>

Can someone help me with this plz? Plz show ur work .... A local high school collected $1590 from 321 people who attended a foot
madreJ [45]
To solve this problem we can use system of equations.
First equation can be
321=x+y 
where x - ppl between 4-17 and y - adult
second equation can be as follows
1590=6*y+4*x
So we have
\left \{ {{321=x+y} \atop {1590=6y+4x}} \right.
From first equation we get value of x in times of y
x=321-y
Now we can substitute it into second eq.
1590=6y+4(321-y) 
now simply if
1590=6y+1284-4y            /-1284 both sides
306=2y                /:2 divide both sides by 2
y=153 
Now we can back substitude
x=321-153
x=168
So we get result
\left \{ {{y=153 - adult} \atop {x=168 - kids}} \right.
