Mathematics

andrew11 [14]3 years ago
4 0

Answer:

PQ = 16.04cm

Step-by-step explanation:

θ = 76°

QR = 4cm

PQ = ?

Since it's a right angle triangle,

QR = adjacent

PQ = opposite

Tanθ = opposite/adjacent

Tan76 = pq / 4

PQ = 4tan76

PQ = 4 * 4.010

PQ = 16.04cm

Answer:

No

Step-by-step explanation:

These are linear equations (y=mx+b). Your slope or m for both equations is 5 and linear equations with the same slope are parallel. Which means they will never cross so they will never have the same amount of tiles.

Adam is 159 centimeters tall and casts a shadow 105 centimeters in height. If Cara is 140 centimeters tall, how many centimeters
vodomira [7]

Answer:

The answer to your question is 12.55 cm

Step-by-step explanation:

Data

Adam                                  Cara

height = 159 cm                  height = 140 cm

shadow = 105 cm                shadow = x

Process

1.- To solve this problem use the Thales' theorem

         Cara's shadow / Cara's height = Adam's shadow / Adam's height

- Substitution

                                     x / 140 = 105 / 159

-Solve for x

                                     x = 105 (140) / 159

-Simplification

                                     x = 14700 / 159

                                     x = 92.45 cm

Cara's shadow is 92.45 cm long.

2.- If both shadows are in line, then Cara must walk forward

                105 - 92.45 cm

                12.55 cm

Please,,, i'm begging you... help me with this and explain how you got the answer... i .. really need someones help.
GalinKa [24]

A "function" is a black box, with a funnel on top, a little door on the  bottom, and a crank on the side.  The way it works is:  

-- You take a number, and call it 'x'.

-- You drop it into the funnel on top of the box, and you turn the crank.

-- Some gears, shafts, math operations and stuff inside the box do things to 'x', and eventually the little door on the bottom opens up and another number falls out.  

-- Before you even touch that one, you call it 'y', and then you pick it up and look at it.

The number that falls out is related somehow to 'x'.  It depends on 'x', AND on exactly what's inside the box ... how the gears and shafts and math operations are all hooked together.  All the guts and parts inside DETERMINE what the box will do to 'x', and how 'x' will get changed, and what will come out the bottom.

We call 'y' the FUNCTION of 'x'.

If you know exactly what's inside the box, then even before you drop 'x' into the funnel, you can always tell in advance WHAT will come out.

If you DON'T know what's inside, then the only way you can describe the function is to take a bunch of numbers, drop them into the function one at  a time, LOOK and SEE what comes out each time, and write it all down.

THAT's what this question is giving you.

What comes out is called the VALUE of the function for each 'x' that you drop in.  The table is giving you the VALUE of 'y' (the function) for seven different 'x's.  Then the question just wants you to look and see what falls out of the box when 'x' is -1 .

Look at the table.  It says that when 'x' is -1, 'y' is going to be <em>3 </em>.  That's the answer to the question.

We still don't know anything about what's inside the box.  We don't know the structure of the FUNCTION, and exactly what it does to 'x' to produce 'y'.  But we do know what'll fall out if we drop a -1 into the funnel ... because the table tells us !

Now, please get up off your knees.  It's unbecoming.

The answer is choice A.

In this problem, we are shrinking the poster by 1/4 of its size.

Which means you need to divide the sides by 4
For width:
w =  \frac{32}{4}  = 8
For length:
l =  \frac{28}{4}  = 7

Benson has a bankruptcy on his credit report, so he pays higher interest rates on his current loans. he calculates that the extr
Scrat [10]

The additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year, option (b) is correct.

<h3>What is simple interest?</h3>

It is defined as the interest on the based on the principal amount, it does not include the compounded amount. The interest calculate on the initial amount or borrowed amount.

We know the formula for the simple interest is given by:

I = PRT

Where I is the simple interest.

P is the principal amount

R is the rate of interest

We have in the question:

I = $180

R = 2% = 0.02

T = 1  year

Put the above values in the formula, we get:

180 = P(0.02)(1)

P = $9000

The additional interest Benson pay each month is:

= 9000/12

= $750

Thus, the additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year option (b) is correct.
