Answer :

6

How :

5 - 2 = 3 + 3 = 6

Answer:

28/53

Step-by-step explanation:

Hey There!

So they want us to find the sine of angle S

well remember is sohcahtoa

S - sine

O - opposite

H - hypotenuse

meaning that

[tex]Sin=\frac{opposite}{hypotenuse}[/tex]

The opposite side of angle S is 28 and the hypotenuse is 53

so [tex]sinS=\frac{28}{53}[/tex]

Answer:

1) E(X) = 1.5

2)SD = 1.118

Step-by-step explanation:

1) Formula for expected value of this set of data is;

E(X) = Σx * P(x)

Σx = 0 + 1 + 2 + 3 = 6

And P(x) = ¼

Thus;

E(X) = 6 × ¼ = 1.5

2) Formula for the standard deviation is;

SD = √Σ((x - μ)²•P(x))

Where μ is the expected value = 1.5

At x = 0,we have;

(0 - 1.5)² × 1/4 = 0.5625

At x = 1, we have;

(1 - 1.5)² × 1/4 = 0.0625

At x = 2, we have;

(2 - 1.5)² × 1/4 = 0.0625

At x = 3, we have;

(3 - 1.5)² × 1/4 = 0.5625

Thus,Σ((x - μ)²•P(x)) = 0.5625 + 0.0625 + 0.0625 + 0.5625 = 1.25

Thus;

SD = √1.25

SD = 1.118

Answer:

Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.

The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:

a + b > c;   a + c > b;   b + c > a

Given a triangle with side length 4 m, 8 m, 9 m:

4m + 8m = 12m > 9m

4m + 9m = 13m > 8m

8m + 9m = 17m > 4m

Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

Answer:

B because 20 cm multiplayer by 9cm equals 180cm

Answer:

  31.243 units

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. Using the attached figure, it is convenient to find the length of BE as an intermediate step in the solution.

  Sin = Opposite/Hypotenuse

  sin(30°) = BE/100

  BE = 100·sin(30°)

Then ...

  Tan = Opposite/Adjacent

  tan(58°) = BE/x

  x = BE/tan(58°) = 100·sin(30°)/tan(58°)

  x ≈ 31.243 . . . . units

_____

Comment on the figure

The intermediate problem in creating the figure was to locate point D. That was accomplished by locating point C on a line at an angle of 58° CCW from the horizontal, using point B as a center. Then D is the intersection of BC with the x-axis. BE is drawn perpendicular to the x-axis.

Answer:

127.41ft^2

Step-by-step explanation:

Given data

DImension of the square

10ft by 10ft

The perimeter of the square is

=10+10+10+10

=40ft

Hence the amount of the fencing of the circle is 40ft

That is the circumference is 40ft

C=2πr

solve for r

40=2*3.14*r

40=6.28r

r= 40/6.28

r=6.37 ft

Area= πr^2

Area= 3.14*6.37^2

Area= 3.14*40.5769

Area= 127.41ft^2

Answer:

m<2 = m<6

m<1 + m<6 = 180

x - 15= 180 - 75 → x = 120°

Answer:

9r^4−r^3s−8r^2s^2+5rs^3+37

Step-by-step explanation:

Distribute the Negative Sign:

=29r4−11r3s+5r2s2+19rs3+4+−1(20r4−10r3s+13r2s2+14rs3−33)

=29r4+−11r3s+5r2s2+19rs3+4+−1(20r4)+−1(−10r3s)+−1(13r2s2)+−1(14rs3)+(−1)(−33)

Answer:

The slope of the line is negative. The y-intercept is 5. The slope of the line is -2/3.

Step-by-step explanation:

With 2 given points on the line that are whole numbers, you can find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex]. The answer will tell you whether it's negative or positive. For example, [tex]m=\frac{-2-1}{4-0} =\frac{-3}{4}[/tex]. The slope is negative for the example. The y-intercept would be the point with 0 as the x-value: (0, -5).

Answer:

$3.50

Step-by-step explanation:

1) 4 friends each bought a movie ticket = 7.50 * 4 = 30

2) subtract from total cost = 58 - 30 = 28

4) total number of candy boxes is 8 (because each friend bought 2 boxes so 4*2 is 8)  = 28/8 = 3.5

5) money so = $3 dollars and 50 cents

Answer:

x=2

Step-by-step explanation:

Distribute the 7 across the 2x and 3:

[tex](7)(2x)-3(7)=7[/tex]

[tex]14x-21=7[/tex]

Isolate the x term by adding 21 on both sides:

[tex]14x=28[/tex]

Isolate x by dividing by 14 on both sides:

[tex]\frac{14x}{14}=\frac{28}{14}[/tex]

[tex]x=2[/tex]
