I need help on finding the LCD

The LCD of the denominator is 12. For this one it is possible to just 'see' that 6 is a divisor of 12. When in doubt, you can always get an answer by just multiplying the denominators. (ie., you can turn 11/12 into 66/72 and 1/6 into 12/72).

In this case, the easiest is to convert 1/6 into 2/12. (multiply both numbers by 2).

Then it becomes:

$9\frac{11}{12} - 9 \frac 2{12} = 9 \frac{11-2}{12} - 9 = \frac9{12} = \frac34$

Find the distance between the points (-3, 9) and (6,-5). Round the answer to the nearest tenth.

inna [77]

Answer:

D. 16.6

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (-3,9)$

$(x_2,y_2) = (6,-5)$

Replacing these values in the distance formula

$D =\sqrt{(-3-6)^2+(9-(-5))^2}$

$D =\sqrt{(-9)^2+(9+5)^2}$

$D =\sqrt{(-9)^2+(14)^2}$

$D =\sqrt{81+196}$

$D =\sqrt{277}$

$D= 16.6433$

Hence the Distance is 16.60 units

Solve for Y: 12y+d=−19y+t

Elina [12.6K]

Answer:

y = t/31 - d/31

Step-by-step explanation:

Solve for y:

d + 12 y = t - 19 y

Subtract d - 19 y from both sides:

31 y = t - d

Divide both sides by 31:

Answer: y = t/31 - d/31

GIVING 100 POINTS!!! An observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a

slamgirl [31]

Answer:

1035.33 feet

Step-by-step explanation:

OBH is a triangle and the sum of the angles of a triangle = 180

∠OBH = 90°

∠OHB = 180 -(49 + 90) = 41°

The law of sines that the ratio of each side of a triangle to the sin of the angle opposite it is the same

Thus

A/sinα = B/sinβ = C/sinγ

where A, B and C are the three sides of the triangle and α, β, γ corresponding respectively to the angles opposite them.

Using the law of sines

$\frac{OB}{sin 41} = \frac{BH}{sin49}$

Therefore BH which is the height the helicopter is flying at is

$BH = OB \frac{sin49}{sin41}$

≈ 1035.33 feet
