The area of AXYZ is žyh
by the definition of the area of a triangle. Using the sine ratio, sin(x) = . Also, asin(x) = h is true by the
multiplication property of equality. So, by the substitution property of equality, the area of AXYZ is 2xysin(x).
Where did Jayden make his first error in the proof?

Answer:

Step-by-step explanation:

Discriminant = b² - 4ac

a = 3 ; b = 24  and c = 48

Discriminant = 24² - 4*3*49

                     = 576 - 576

                      = 0

As discriminant is 0, there is only 1 real root.

When you add 2 of the sides together, they are always greater than the other

Step-by-step explanation:

8: (y-6) (y+8)

steps: m + n = 2 and m×n = -48 so m is 8 and n is -6

Answer:

$8,706

Step-by-step explanation:

Lionnel is considering doing some long term investments with the money she inherited

She would like to have $50,000 at the end of 30 years

The interest is 6%

Therefore the amount that Lionnel would need to put into the account can be calculated as follows

A= P(1+r)^t

50,000 = P(1+6/100)^30

50,000 = P (1+0.06)^30

50,000 = P(1.06)^30

50,000= 5.7434P

P = 50,000/5.7434

P= $8,706

Hence Lionnel will need to put $8,706 into an account earning 6% interest

The minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes is  12.5 square feet.

Side of each cube = 10 inches

Number of cubes =3

As we know The minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes will be the total surface area of all 3 boxes.

The total surface area of a cube with side a is 6a².

So, the total surface area of a cube with a side of 10 inches will be 6*10² = 6*100 = 600 square feet.

So, the total surface area of 3 cubes with a side of 10 inches will be 600*3 = 1800 square inches.

As we know that 1 square inch = 0.00694444 square feet

So, 1800 square inches = 1800*0.00694444 = 12.5 square feet.

Therefore, the minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes is  12.5 square feet.

Answer:

NM = [tex]\sf \sqrt{70}[/tex]

Step-by-step explanation:

Let NM = y

If KL is twice the length of NM, then KL = 2y

Given:

As ΔKLN ~ ΔNOM

   KL : KM = NO : NM

[tex]\sf \implies 2y : 20 = 7 : y[/tex]

[tex]\sf \implies \dfrac{2y}{20}=\dfrac{7}{y}[/tex]

[tex]\sf \implies 2y \cdot y=7 \cdot 20[/tex]

[tex]\sf \implies 2y^2=140[/tex]

[tex]\sf \implies y^2=70[/tex]

[tex]\sf \implies y=\sqrt{70}[/tex]

As NM = y, then NM = [tex]\sf \sqrt{70}[/tex]

Answer:

NM = [tex]\sqrt{70}[/tex]

Step-by-step explanation:

Δ NMO and Δ KML are similar ( by the AA postulate )

Then the ratios of corresponding sides are in proportion, that is

[tex]\frac{NM}{KM}[/tex] = [tex]\frac{NO}{KL}[/tex] ( substitute values, noting KL = 2NM )

[tex]\frac{KM}{29}[/tex] = [tex]\frac{7}{2NM}[/tex] ( cross- multiply )

2 NM² = 140 ( divide both sides by 2 )

NM² = 70 ( take the square root of both sides )

NM = [tex]\sqrt{70}[/tex]

Answer:

2:00 PM

Step-by-step explanation:

I figured out that the car is going 40 mph seeing as how it went 20 miles in 30 minutes.

I used this and found out how many hours it would take to get to 200 miles at this rate:

200/40 = 5

I divided 40 by 200 as 200 is the end goal and the car is going 40 mph.

The 5 is 5 hours, so I added 9 and 5 to get 14 which is 2:00 PM

Hope this helps!! :)

Solving a linear equation we will see that after5 weeks you will have $105 on your piggy bank.

We know that it starts ar $45, and then you add $12 each week. Then the amount of money after W weeks is modeled by the linear equation:

y = 12*W + 45

You will have $105 when the value of y is 105, replacing that we get the equation below:

105 = 12W + 45

105 - 45 = 12W

60 = 12W

60/12 = W

5 = W

You will have $105 on your piggy bankafter 5 weeks.
