Step-by-step explanation:

Answer:

a = 1.8 to the nearest tenth.

Step-by-step explanation:

Remark

I don't think this case is ambiguous. It has only 1 solution, I think.

Step One

Find the top angle.

All triangles have 180 degrees.

15 + 105 + x = 180

120 + x = 180                     Subtract 120 from both sides

x = 180 - 120

x = 60

Step Two: Find a

a/sin(60) = 2/Sin(105)       Multiply both sides by sin(60)

a = 2 *  Sin(60) / sin(105)

a = 2 * .8660 / 0.9659

a = 1.793

Answer:

10.8

divide 9 by 5/6

Answer:

200 stamps

Step-by-step explanation:

Divide the 90 stamps by 45: The result is 2; it's equal to 1% of the total number of stamps. You then multiply it by 100 to get the full amount, which is 200 stamps.

Answer:

6

Step-by-step explanation:

Greatest common factor (GCF) of 42 and 60 is 6.

As the numbers get larger, or you want to compare multiple numbers at the same time to find the GCF, you can see how listing out all of the factors would become too much. To fix this, you can use prime factors.

List out all of the prime factors for each number:

Prime Factors for 42: 2, 3, and 7

Prime Factors for 60: 2, 2, 3, and 5

Now that we have the list of prime factors, we need to find any which are common for each number.

Looking at the occurences of common prime factors in 42 and 60 we can see that the commonly occuring prime factors are 2 and 3.

To calculate the prime factor, we multiply these numbers together:

GCF = 2 x 3 = 6

(hope this helps can i plz have brainlist :D hehe)

Answer:

True, yes, fact, there's no answer choices so sorry if this doesn't hep

Step-by-step explanation:

Answer:

so 5w +3w=8w+12w= 20w -10 so the answer is 20w-10 that is how I learned

Answer:

x = 60

Step-by-step explanation:

(x+22) + (x+6) + (x-28) = 180

x + 22 + x + 6 + x - 28 = 180

x + x + x + 22 + 6 - 28 = 180

3x = 180

x = 180/3

x = 60

Answer:

0.126

Step-by-step explanation:

Given :

Total time interval = 720

Number of interval in which one vehicle is detected =508

Proportion of atleast one detected vehicle :

508 / 720 = 0.7056

The mean arrival rate per second :

P(x ≥ 3) = 1 - P(x ≤ 3)

P(x ≥ 3) =1 - [p(x =0) + p(x = 1) + p(x =2) + p(x = 3)]

P(x ≥ 3) = 1 - 0.8745

P(x ≥ 3) = 0.1255

P(x ≥ 3) = 0.126

Answer:

All I know is that the -3 should be there without the 1/3 because that makes no sense to me. And...

Step-by-step explanation:

3x+8=-4

Subtract 8 from both sides.

3x+8−8=−4−8

3x=−12

Step 2: Divide both sides by 3.

3x=−12

3       3

x=−4

Answer: Tyler's work is incorrect because when subtracting 8 from both sides of the equation, he didn't subtract it from -4. If he subtracted 8 from -4, it would've been 3x=-12.

The correct answer is x = -4

Step-by-step explanation:

you get x = -4 by subtracting 8 from each side of the equation, resulting in 3x = -12

then you divide both sides by 3, leaving you with x = -4

It is only 5 point not 100,she cappin

Step-by-step explanation:

Answer:

8%

Step-by-step explanation:

the answer is right their in the ratio and the class as a whole would be 18 so there are 8 girls (8%) and 10 boys(10%)

Answer:

28%. mark got 28% WRONG

Step-by-step explanation:

another way to write 18/25 is 18 divided by 25. 18/25=0.72. 0.72 as a percentage is 72%. You are asking what percent he got wrong. 100%-72%=28%. Mark got 28% wrong/

Answer:

[tex]T_n =-\frac{8}{3} (-3)^{n}[/tex]

Step-by-step explanation:

Given

[tex]Sequence: 8, -24, 72[/tex]

Required

Determine the n term

The above sequence is geometric. So, we calculate the common ratio first:

[tex]r = \frac{T_2}{T_1}[/tex]

[tex]r = \frac{-24}{8}[/tex]

[tex]r = -3[/tex]

The equation is then calculated using:

[tex]T_n = ar^{n-1}[/tex]

Where

[tex]a = T_1 = 8[/tex]

and

[tex]r = -3[/tex]

The equation becomes:

[tex]T_n =8 * (-3)^{n-1}[/tex]

Apply law of indices:

[tex]T_n =8 * (-3)^{n} * (-3)^{-1}[/tex]

[tex]T_n =8 * (-3)^{n} * \frac{1}{-3}[/tex]

[tex]T_n =-8 * (-3)^{n} * \frac{1}{3}[/tex]

[tex]T_n =-\frac{8}{3} * (-3)^{n}[/tex]

[tex]T_n =-\frac{8}{3} (-3)^{n}[/tex]

Answer:

It would be a reflection across the x-axis, followed by a composition translation of -6 units x, and 1 unit y.

Step-by-step explanation:

If you were to graph each shape and follow this procedure, you will go from parallelogram ABCD to parallelogram A''B''C''D''.

[tex]\frac{(27 * \frac{1}{2} + e^{2} )}{\frac{1}{3} } \\\\e = 5\\\\\\27 * 0.5 + 5^{2} = 13.5 + 25 = 38.5\\\\\frac{38.5}{\frac{1}{3} } = 3 * 38.5 = 115.5[/tex]

Answer:

Angle 7 and 9 = 49 degrees.

Angle 8 and 10 = 41 degrees

Answer:

it is 2

Step-by-step explanation:

Answer:

(g x h)(n) = -3n(n^2+2n+4) + 2(n^2+2n+4)  

(g x h)(n) = -3n^3-4n^2 -8n + 8

(g x h)(1) = -3n^3-4n^2 -8n + 8 = -3 -4 -8 + 8 = -7

Step-by-step explanation:

Answer:

1.  n = 0

   n = f -4

2.   n = - 2/g+2

Answer:

x=9

Step-by-step explanation:

Original equation: 16x-8-14x=10

Combine like terms: 2x-8=10

Add 8 to both sides: 2x=18

Divide by 2 on both sides: x=9

Let me know if this helps!

Answer:

x=9

Step-by-step explanation:

16x-8-14x=10

16x+-8+-14x=10

(16x+-14x)+(-8)=10 ( Combine like terms)

2x-8=10

Add 8 to both sides

2x-8=10

+8 +8

2x=18

Divide both sides by 2

2x=18/2

x=9

Answer:

comparing both the equation,

3X-3=6x-1

or, -2 =3X

or, X= -2/3

Y=6X-1

or, Y= 6× -2/3 -1

or, Y= -4-1

or, Y= -5

hence the required solution is (-2/3, -5)
