Answer:

x =-5 and y = -6

Step-by-step explanation:

In order to get the answer, I used the elimination/addition method

8y-9x= -3 <— I decided to eliminate the y

5y-8x= 10 <— I decided to eliminate the y

5(8y-9x = -3) <— switch up the number of y from the bottom to multiply

-8(5y-8x= 10) <— switch up the number of y from the top to multiply, but have a negative sign to it

So...our new equation will be....

40y - 45x = -15

+ -40y + 64x = -80

________________________

19x = -95

x = -5

8y-9x= -3

8y-9(-5) = -3

8y+45 = -3

- 45 = - 45

8y = -48

y = -6

Answer:

[tex]7.4^{o}[/tex]

Step-by-step explanation:

Altitude of the plane = 4 miles

Distance from the plane to the airport = 31 miles

Let the angle of depression from the plane to the airport be represented by θ. Thus applying the appropriate trigonometric function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

          = [tex]\frac{4}{31}[/tex]

          = 0.1290

θ = [tex]Tan^{-1}[/tex] 0.1290

  = 7.3506

θ = [tex]7.4^{o}[/tex]

The angle of depression from the plane to the airport is [tex]7.4^{o}[/tex].

This inequality will be represented by an arrow starting from 7 and directed towards the right. Option 3 will be the correct answer.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Given inequality is,

3m [tex]\geq[/tex] 21

To find the solutions to the given inequality solve this inequality first.

3m/3  [tex]\geq[/tex] 21/3

m  [tex]\geq[/tex] 7

This inequality will be represented by an arrow starting from 7 and directed towards the right.

Since, inequality is having a sign notation of greater than equal to, the arrow will start with a dark circle located at 7.

Therefore, Option 3 will be the correct answer.

Answer:

12/y

Step-by-step explanation:

if you see in the picture the first three numbers 3,6 and 9 you add 3 in each number like 3+3=6 then 6=3 = 9 and 9 + 3 = 12 and so on. ( 45 also comes in this pattern )

Answer:

WY = 28

Step-by-step explanation:

Using the pythagorean theorem, we can find out the measures of lenghts WX and YX individually.

VX^2 = VW^2 + WX^2

ZX^2 = ZX^2 + XY^2

Substitute

400 = 256 + WX^2

400 = 144 + XY^2

Simplify

WX^2 = 144

XY^2 = 256

WX = 12

XY = 16

WY = 28

The common denominators of the given fractions  [tex]\frac{1}{4}[/tex] and [tex]\frac{7}{10}[/tex] are 20 and 40.

What is a fraction ?

A fraction is used to represent a portion or component of a whole. The numerator and denominator are its two parts.

The two fractions are given which are : [tex]\frac{1}{4}[/tex] and [tex]\frac{7}{10}[/tex] .

We know that the numerator is the top or upper value in a fraction whereas a denominator is lower or bottom value in a fraction.

Here , the denominators in both the fractions are 4 and 10 respectively.

To find out the common denominators for both the fractions , we need to calculate the common multiples of 4 and 10.

Multiples of 4 are :

4 , 8 , 12 , 16 , 20 , 24 , 28 , 32 , 36 , 40 , 44

Multiples of 10 are :

10 , 20 , 30 , 40 , 50

Common multiples are :

20 and 40

This meant , common denominators will be 20 and 40.

Answer:

17

Step-by-step explanation:

Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. It takes 17 year for the value of the account to reach $12,110.

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Compound Interest =P(1+r/n)^rt

Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. for the value of the account to reach $12,110 we need to find the time it takes.

The principal amount = $7,200

Rate = 3.1%

Compound Interest = [tex]P(1+r/n)^{rt}[/tex]

                      12,110  =  [tex]7200(1+3.1/12)^{3.1t}[/tex]

                            t = 17

Thus, for the value of the account to reach $12,110 the time taken is 17.

Answer: 306

Step-by-step explanation:

Formula to find sample size:

[tex]n=(\dfrac{\sigma\times z^*}{E})^2[/tex] , where [tex]\sigma[/tex] = standard deviation, E = margin of error, z* = critrical z-value.

As per given,

[tex]\sigma=9.5 , E=1.4[/tex]

Critical z-value for 99% confidence = 2.576

Now , the minimum sampl size :[tex]n=(\dfrac{9.5\times2.576}{1.4})^2[/tex]
