What is the measure of angles A, B and C in the given triangles?

Answer:

[tex]1\frac{1}{2}[/tex]

Step-by-step explanation:

The first step to solving this problem is to convert these into improper fractions.

[tex]7\frac{2}{3} =\frac{21+2}{3}=\frac{23}{3}[/tex]

[tex]5\frac{1}{9} =\frac{45+1}{9}=\frac{46}{9}[/tex]

The second step is to determine the reciprocal of the second term.

Reciprocal of [tex]\frac{46}{9} =\frac{9}{46}[/tex]

The third step is to multiply the first term by the reciprocal of the second term.

[tex]\frac{23}{3}*\frac{9}{46}=\frac{207}{138}[/tex]

The fourth step is to reduce this fraction.

[tex]\frac{207}{138}=\frac{3(69)}{3(46)}=\frac{23(3)}{23(2)}=\frac{3}{2}=1\frac{1}{2}[/tex]

Answer:

1 1/2 or 3/2

Step-by-step explanation:

First you need to make your fractions improper.

7 times 3 + 2 = 23, so the fraction is 23/3

5 times 9 + 1 = 46, so the fraction is 46/9

Since this is division, flip the second fraction.

So instead of 46/9, it's now 9/46

Now you can multiply.

23/3 + 9/46 = 207/138

207/138 simplified is 3/2, or  1  1/2

(2x - 20) = 20

(4x - 10) = 70

Answer:

x = 2

Step-by-step explanation:

Since we know one root is -3, we know one factor of the equation is (x+3)

From there we can use the factor we know to factor the rest of the equation:

x^2 + x - 6 = (x+3) * ?

Since know -6 is just 3 * -2 and since 3-2 is 1,

(x+3)(x-2) = x^2 + x - 6

From there,

x - 2 = 0

x = 2

Answer:

ADE = 63°

Step-by-step explanation:

One thing at a time. We can start telling that triangle ADE is isosceles, of baseAD. Means the two angles EAD e ADE are congruent, and each measures  [tex]\frac {180-54}2 = 63°[/tex].

Now look at angles EDA and ECB. They are corresponding angles relative to the parallels DA and CB, so they are congruent. Measure of angle C is the same of measure of angle ADE = 63°

Edit: I've been asked for the rest of the measures. Purple ones are the one you find during the exercize. Red ones are the remaining. External ADC is supplementary to ADC (it's an external angle) angle BAD is alternate to ADE respect to the two parallels AB and CE, so they are congruent. Angle ABC is supplementary to angle BCD since they're internal conjugate relative to the same two parallels.

Step-by-step explanation:

-9y - 10 = x

x = -9y - 10

5x + 6y = -11

5(-9y - 10) + 6y = -11

-45y - 50 + 6y = -11

(-45 + 6)y = -11 + 50

-39y = 39

y = 39/-39

y = -1

x = -9y - 10

x = -9(-1) - 10

x = 9 - 10

x = -1

Answer:

first, simplify the equation, 5x-8x is -3x. So 6-7x = -3x+10

now subtract 6 from both sides, -7x = -3x+4

now add 3x on both sides. -4x = 4. now divide 4/-4 is -1. Thus X=-1

Answer:

x=-1

Step-by-step explanation:

6 - 7x = 5x - 8x + 10

First move the variables (x) to one side:

6 - 7x = 5x - 8x + 10

  +7x                +7x

6 = 5x - 8x + 7x + 10

Subtract 10 from both sides:

6 = 5x - 8x + 7x + 10

-10                           -10

-4 = 5x - 8x + 7x

Simplify:

4x = -4

Divide by 4 to isolate x:

4x = -4

÷4     ÷4

x=-1

Answer:

Firstly, we are told that the value we are supposed to convert is "330 meters per second." When we see the word "per," we know that the unit should be divided.

So, really, the value is:

[tex]330\ \frac{meters}{second}[/tex]

Which can be abbreviated to:

[tex]\frac{330\ m}{1\ sec}[/tex]

We can scratch off the last two answers because they involve an x, and that is not our given value.

We can also eliminate the second answer because we are supposed to convert to kilometers, which is abbreviated by "km."

So, the answer is A or:

[tex](\frac{330\ m}{1\ sec})(\frac{1\ km}{1000\ m})[/tex]

The equivalent expression is [tex](a)\ \frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]

Speed is the rate of change of distance over time

The speed in meter per second is given as:

[tex]Speed =330m/sec[/tex]

To convert from meters to kilometers, we simply multiply the distance by 0.001.

So, we have:

[tex]Speed =\frac{330m}{sec} \times 0.001[/tex]

Express 0.001 as 1/1000

[tex]Speed =\frac{330m}{sec} \times \frac{1}{1000}[/tex]

Rewrite as:

[tex]Speed =\frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]

Hence, the equivalent expression is [tex](a)\ \frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]

Answer:

39

Step-by-step explanation:

6x6=36+3=39

Answer:

D^2 = (x^2 + y^2) + z^2

and taking derivative of each term with respect to t or time, therefore:

2*D*dD/dt  =  2*x*dx/dt  + 2*y*dy/dt  + 0 (since z is constant)

divide by 2 on both sides,

D*dD/dt = x*dx/dt + y*dy/dt

Need to solve for D at t =0,  x (at t = 0) = 10 km,  y (at t = 0) = 15 km

at t =0,

D^2 =  c^2 + z^2 = (x^2 + y^2) + z^2  =  10^2 + 15^2 + 2^2  = 100 + 225 + 4  = 329

D = sqrt(329)

Therefore solving for dD/dt, which is the distance rate between the car and plane at t = 0

dD/dt = (x*dx/dt + y*dy/dt)/D  =  (10*190 + 15*60)/sqrt(329)  = (1900 + 900)/sqrt(329)

= 2800/sqrt(329) = 154.4 km/hr

154.4 km/hr

Answer:

x=3

the trangal is isosoles so both sides need to equal 10 so the equation would be 4x-2=10.

frist you would add both sides by 2

4x-2=10

    +2 +2

4x=12

then you would divide both sides by 4

4x/4=12/4
