One side of a right triangle has a length of 12 feet. Which of the following could be lengths for the two other sides of the rig

Elodia [21]

Answer:

Step-by-step explanation:

Apply the Pythagorean Theorem to determine whether or not the given triplets represent right triangles or not:

I. 5 feet and 13 feet: 5^2 + 12^2 = 13^2 is TRUE

II. 9 ft and √63 ft: 9^2, 63, 12^2: 63 + 81 do add up to 144 TRUE

III. 2, 10, 12^2: 2 + 10 do NOT add up to 144. FALSE

Answer B is correct

Help with geometry question

nata0808 [166]

Answer:

Step-by-step explanation:

The area of this parallelogram is

A=hb (height times base)

h=A/b, we see A=14.4mi^2 and b=4.8mi so

h=(14.4mi^2)/(4.8mi)

h=3 mi

X² - xy = 0<br> x + y = 1

wolverine [178]

Answer:

(0, 1 ) and ( $\frac{1}{2}$ , $\frac{1}{2}$ )

Step-by-step explanation:

Given the 2 equations

x³ - xy = 0 → (1)

x + y = 1 → (2) ( subtract x from both sides )

y = 1 - x → (3)

Substitute y = 1 - x into (1)

x² - x(1 - x) = 0

x² - x + x² = 0

2x² - x = 0 ← factor out x from each term on the left side

x(2x - 1) = 0

Equate each factor to zero and solve for x

x = 0

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = $\frac{1}{2}$

Substitute these values into (3) for corresponding values of y

x = 0 : y = 1 - 0 = 1 ⇒ (0, 1 )

x = $\frac{1}{2}$ : y = 1 - $\frac{1}{2}$ = $\frac{1}{2}$ ⇒ ( $\frac{1}{2}$ , $\frac{1}{2}$ )

A 2?-ft wide circular track for a camera dolly is set up for a movie scene. The two rails of the track form concentric circles.

navik [9.2K]

Answer: A wheel on the outer rail travel 12.57 ft more than a wheel on the inner rail of the track.

Step-by-step explanation:

Since we have given that

Radius of inner circle = 57 ft

As we know the formula for "Circumference of circle":

$Distance=Circumference=2\pi r\\\\Distance=2\times \frac{22}{7}\times 57\\\\Distance=358.28\ Ft$

Since we have also mentioned that there is 2 feet wide circular track for a camera dolly.

So, Radius of outer circle will be given as

$57+2\\=59\ ft$

So, Distance = Circumference is given by

$Distance=2\pi R\\\\Distance=2\times \frac{22}{7}\times 59\\\\Distance=370.85\ ft$

Hence, Difference between the outer rail travel than a wheel on the inner rail travel is given by

$370.85-358.28\\\\=12.57\ ft$

Therefore, A wheel on the outer rail travel 12.57 ft more than a wheel on the inner rail of the track.

Meredith borrows $12,560 and pays 2 percent simple interest each year for 4 years. What is the total amount of interest that she

abruzzese [7]

Meredith borrow 12,560 so if you do some basic calculations, %2 of that is 251.20 dollars of interest per year

The total amount of interest she will pay for 4 years (251.20 x 4) is 1004.80 dollars for 4 years.
