Points A,B, and C are collinear. Point B is between A and C. Find the length indicated.
BC = x + 15, AC = 14, and AB = x + 7.
Find AB

a) 4
b) 5
c) 3
d) 6​

3.6 is the answer to the question

Answer:

c

Step-by-step explanation:

Answer:

C: x+y=27 and y=6+2x

Step-by-step explanation:

First part: If the sum of the two is 27, then it means that it is x + y = 27, because sum means addition.

Second part: The larger number (y) is 6 more than twice the smaller number (x). Twice a number means that it is that number multiplied by x, so it is 2x. 6 more means we add 6 to it so the second equation is y=6+2x.

If Alex and Leonardo are both buying two bags of popcorn and drinks then the overall price would be $18.00.

$4.00 + $4.00 = $8.00 + $5.00 + $5.00 = $18.00

Therefore, they would spend 18 dollars.

The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.

The speed   is the distance travelled per unit of time by a sound wave  

Speed of sound in water is [tex]1.46 \cdot 10^3[/tex]

Speed of sound in air is [tex]3.31 \cdot 10^2[/tex]

To find how much faster does travel , we need to subtract  the speed

To subtract we need to make the exponents same

[tex]1.46 \cdot 10^3\\14.6 \cdot 10^2[/tex]

Now we subtract ,

 [tex]14.6- 3.31= 11.29\\\\11.29 \cdot 10^2\\1.129 \cdot 10^3[/tex]

The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.

6.                   x = -6                                   Symmetric property

Answer:

To get from step 1 to step 2, apply the distributive property to eliminate the parentheses.

To get from step 2 to step 3, combine like terms on the right side of the equation.

To get from step 3 to step 4, apply the addition property of equality to isolate the variable term.

To get from step 4 to step 5, apply the multiplication property of equality to isolate the variable, x.

To get from step 5 to step 6, apply the symmetric property to rewrite the equation with the variable on the left side.

Answer:

-2 degrees

Step-by-step explanation:

Divide -16 by 8:

-16/8

= -2

So, the average change in temperature each hour was -2 degrees.

The average change of weather dropped 2 degrees for every hour is snowed.

Here,

After 8 hours of snow, the temperature had changed by a total of -16 degrees.

We have to find the average change in temperature in each hour.

What is Average?

Average is the middle value of the given sets of values.

Now,

After 8 hours of snow, the temperature had changed by a total of -16 degrees.

Hence, The average change in temperature in each hour = -16 ÷ 8 = -2

Therefore, The weather dropped 2 degrees for every hour is snowed.

Answer:

sin70°

Step-by-step explanation:

Given sin110° where 110° is an obtuse angle in the second quadrant.

The related acute angle in the first quadrant is 180° - 110° = 70°

Thus

sin110° = sin70°

Let's say that we don't have jokers. In that case, there are 52 cards, and half of them are red (so 26 are red). The probability of pulling a red card once is 1/2 since half the cards are red.

If we pick one out, there are only 51 total cards left and 25 red cards. So, the probability of picking one again would be 25/51.

We multiply the probabilities of these two events to find the probability of them both happening.

1/2×25/51=25/102

The probability of picking two red cards in a row is 25/102 or around 24.5%.

The best method would certainly be integration :)

The area is given by the integral,

[tex]\displaystyle\int_0^2\frac{\mathrm dx}{9-x^2}[/tex]

We can split up the integrand into partial fractions:

[tex]\dfrac1{9-x^2}=\dfrac16\left(\dfrac1{3-x}+\dfrac1{3+x}\right)[/tex]

Then the area is

[tex]\displaystyle\frac16\int_0^2\left(\frac1{3-x}+\frac1{3+x}\right)\,\mathrm dx[/tex]

[tex]=\dfrac16(-\ln|3-x|+\ln|3+x|)\bigg|_0^2[/tex]

[tex]=\dfrac16\left((\ln5-\ln1)-(\ln3-\ln3)\right)=\boxed{\dfrac{\ln5}6}[/tex]

Answer:

B

Step-by-step explanation:

To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.
