If ∆ABC ∼ ∆PQR such that AB = 1.8cm and PQ = 1.6 cm, what is the ratio of the areas of ∆ABC and ∆PQR.

Answers

Answer 1

Answer:

81 / 64

Step-by-step explanation:

The ratio of the areas can be obtained thus :

Area of ∆ABC / Area of ∆PQR

Area of ∆ABC / Area of ∆PQR = AB² / PQ²

AB = 1.8 ; PQ = 1.6

AB² / PQ² = 1.8² / 1.6²

= 18² / 16²

= 324 / 256

= 81 / 64

Use the Distributive Property to simplify the expression.
1(8+x+4) = 0

Answers

Answer:

x + 12 = 0

Step-by-step explanation:

Answer:

x = -12

Step-by-step explanation:

1 x 8 = 8

1 x x = 1x

1 x 4 = 4

rewrite expression

8 + 1x + 4 = 0

combine like terms

8 + 4 = 12

1x + 12 = 0

subtract 12 from both sides

12 - 12 = 0

0 - 12 = -12

1x = -12

divide by 1 on both sides to get x by itself

1x/1 = x

-12/1 = -12

The slope is 3, count from one point to o other. If you go from -2,0 up to -1,3 you go up 3 and over one so the slope is 3

Answer:

Step-by-step explanation:

Remark

All you need is 2 points that you can rely on as being accurate.

(2,0) should certainly be one of them. I would pick (-1,3) as the other but it is less certain.

Givens

y2 =3

y1 = 0

x2 = -1

x1 = - 2

Formula

m = (y2 - y1)/(x2 - x1)

Solution

m = (3 - 0) / (-1 - - 2)

m = (3 )/ (-1 + 2)

m = 3/1

m = 3

An appliance is for sale at either (a) P15,999 cash or (b) on terms, P1,499 each month for the next 12 months.  Money is 9% compounded monthly.  Which is lower, the cash price or the present value of the installment terms? Explain.​

Answers

Answer:

Cash price

Step-by-step explanation:

The computation is shown below:

The Interest rate per month (r) = (9% ÷ 12) = 0.75%

Now Present value of the monthly payment is

= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}

= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}

= 18,748.89

And the cash price is 15,999

So, the cash price would be lower

The cash price would be lower. A further explanation is below.

According to the question,

Interest rate per month,

[tex]r = \frac{9 \ percent}{12}[/tex]

  [tex]= 0.75[/tex] (%)

hence,

The Present value of the monthly payment will be:

= [tex]PMT\times \frac{{(1 + Interest \ rate)^{number \ of \ years} - 1}}{Interest \ rate}[/tex]  

= [tex]1499\times \frac{[(1 + 0.75 \ percent)^{12} - 1] }{0.75 \ percent}[/tex]  

= [tex]18748.89[/tex]

As we can see that the cash price is 15,999. Thus the above answer is right.

Answers

The answer is 50x+200

answer:

the equation would be

200 + ( 50 * x ) = total cost

x is variable for the number of months  

but lets use the number 2 ( 2 months ) for example

200 + ( 50 * 2 ) =

using pemdas we solve what is in the parentheses first

50 * 2

= 100

then just add the following numbers since they are the only ones left over in the problem

100 + 200

now we know that in 2 months and if you chose this cell phone plan, you will have to spend 300 dollars even!

Calculate the length of the side LN given the following data for 37°.

Cos 37° = 0.790

pls help ASAP

Answers

Answer:

It is given that,

Sin 37° = 0.602

Cos 37° = 0.790

Tan 37° = 0.754

To find:

The length of side LN.

Solution:

In a right angle triangle,

[tex]\sin\theta =\dfrac{Perpendicular}{Base}[/tex]

Using this in triangle LMN, we get

[tex]\sin (37^\circ) =\dfrac{LM}{LN}[/tex]

[tex]0.602=\dfrac{6}{LN}[/tex]

[tex]0.602LN=6[/tex]

Divide both sides by 0.602.

[tex]LN=\dfrac{6}{0.602}[/tex]

[tex]LN=9.966777[/tex]

[tex]LN\approx 9.97[/tex]

Therefore, the correct option is C.
