Answer:

third side is 2√33

Step-by-step explanation:

Hi there!

We need to find the third side (hypotenuse, or the side opposite to the right angle) of the triangle, and we're given the measures of the 2 other sides (legs, or the sides make up the right angle)

To find the hypotenuse, we can use Pythagorean theorem, which is given as:

a²+b²=c², where a and b are the legs, and c is the hypotenuse

as stated above, we know that the legs are 7 and √83

substitute them as a and b into the theorem

remember that (√x)²=(√x)(√x)=x

7²+(√83)²=c²

raise all numbers (multiply 7 by itself and multiply √83 by itself)

49+83=c²

add 49 and 83 together

132=c²

take the square root of both sides

√132=c

the question asks for simplest radical form, written as x√y, where x is the square root of a perfect square, and y is what's left after the prefect square is pulled out. For example, 2√3 is √12 (12 is 4*3, and 4 is a perfect square. Recall that √xy is equal to √x*√y. Taking the square root of 4 gives us 2, while taking the square root 3 gives us √3. Multiplying them together makes the number 2√3)

132 is divisible by 4 (the last two digits makes 32, which is divisible by 4). 132/4=33

so 132 is 4*33

pull out 4 from under the radical, take the square root of it, and leave √33 as is

the simplified radical form is 2√33

So the third side is 2√33

Hope this helps!

Answer:

B = -25

Step-by-step explanation:

Note :-

Firstly there's no options mentioned in the question . So I would be providing you with the location of point B !

Given :-

By question , the Point A is at -20. And B is 5 less than A. So the location of point B on the number line is ,

→ B = -20 - 5

→ B = -25

Answer:

Original price of bicycle = $864

Step-by-step explanation:

Given:

Rate of tax = 20%

Price pay by Mathew = $1,080

Find:

Original price of bicycle

Computation:

Original price of bicycle = Price pay by Mathew[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-0.2)]

Original price of bicycle = 1,080[1 / (0.8)]

Original price of bicycle = 1,080[1.25]

Original price of bicycle = 1,080[1.25]

Original price of bicycle = $864

Answer:

Answer = D

Step-by-step explanation:

If you add all of the heights up you get 480. divide that by ten (because there were 10 students whose height was taken) then you get 48. therefore, the typical second-grade student is about 48 inches tall.

I hope this helps have a good day :)

The typical second-grade student is about 48 inches tall.

'Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.'

According to the given problem,

Given data = { 44, 45, 47, 49, 48, 48, 49, 50, 48, 52 }

Sum of the given data = 44 + 45 + 47 + 49 + 48 + 48 + 49 + 50 + 48 + 52

                                     = 480

Average of the given heights = [tex]\frac{480}{10}[/tex]

                                                 = 48

Hence, we can conclude,  The typical second-grade student is about 48 inches tall since the average of the given data is 48.

Step-by-step explanation:

The question is incomplete, as the map or the scale length of the plants are not given.

To solve this, I will assume that:

[tex]Scale\ Distance = x[/tex]

[tex]Scale\ Ratio = 1\ unit : 1\ km[/tex]

Required

The total length

To get the total length (actual length), multiply the scale ratio by the scale distance;

[tex]Actual = Scale\ Distance * Scale\ Ratio[/tex]

So, we have:

[tex]Actual = x * 1km[/tex]

[tex]Actual = x\ km[/tex]

Assume that:

[tex]x = 5[/tex]

The total length will be:

[tex]Actual = 5km[/tex]

Answer:

80 meters

Step-by-step explanation:

Length of rectangular field = x

Width of rectangular field = 50

Meters of Fencing required = perimeter of rectangle = 260 m

Perimeter of a rectangle = 2(length + width)

260 = 2(x + 50)

260 = 2x + 100

260 - 100 = 2x

160 = 2x

x = 160 / 2

x = 80 meters

[tex] \frac{ba}{ac} = \frac{h}{rt} [/tex]

solve for h

Answer:

Step-by-step explanation:

assuming that the triangles are similar,  which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.

' = feet

" = inches

h / 20' = 4'-2" / 3'-4"

just use inches for this,  it's easier

h / 240" = 50" / 40"

h = 240 ( 50 / 40 )

h = 300"

h = 25'

Cross Products

Cross product of two non-collinear vectors is a third vector which is orthogonal to the first two. The magnitude of the cross product equals the area of a parallelogram having the two given vectors as sides.

The the cross product u x v of vectors u<u1,u2,u3> and v<v1,v2,v3> is the value of the determinant formed by the direction vector <i,j,k> and u, v :

i     j    k

u1 u2 u3

v1 v2 v3

which evaluates to

P = u x v = (u2*3 - u3*v2)i – (u1*v3 - v1*u3)j + (u1*v2 – v1*u2)k = <p1, p2, p3>

The magnitude, which equals the area of the parallelogram, is the norm of P

Area = ||P|| = sqrt(p1²+p2² +p3²)

Plugging in values,

u<-4,-9,1>

v<-6,1,5>

Cross product P=(-45-1)i+(20-6)j+(-54-4)k =<-46+14-58>

Magnitude = sqrt((-46)^2+(14)^2+(-58)^2) = 2sqrt(1419)=75.34 (approx.)

So the area of the parallelogram is 75.3 approx.
