Answer:

see below

Step-by-step explanation:

The product of two negative integers is positive

True    -*- = +

The product of two integers with different signs is positive

False - *+ = -

Two numbers are the same sign then the product is positive

True -*- = +   and +*+ = +

The product of a positive and a negative is negative

True - * + = -  and + * - = -

The signs of two integers are different, then the product is positive.

False  - * + = -  and + * - = -

Answer:

[tex]\boxed{D = 8.5 \ units}[/tex]

Step-by-step explanation:

The coordinates are (5,7) and (-3,4)

Distance Formula = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

D = [tex]\sqrt{(-3-5)^2+(4-7)^2}[/tex]

D = [tex]\sqrt{(-8)^2+(-3)^2}[/tex]

D = [tex]\sqrt{64+9}[/tex]

D = [tex]\sqrt{73}[/tex]

D = 8.5 units

Answer:

  all are 90°

Step-by-step explanation:

Vertical angles are congruent, and linear angles are supplementary, so we have ...

  ∠AOC + ∠COB + ∠BOD = 270°

  180° + ∠BOD = 270°

  ∠BOD = 90°

Since the lines cross at right angles, all of the angles are 90°.

Step-by-step explanation:

Ratio of adults to children= 7:3

Total no. Of people at the cricket match:150

To find the value of the ratios, 7x+3x=150 ; 10x=150 ; x=150/10:15

So, 7:3 is 7(15) adults to 3(15) children,

Total no. Of adults: 105

Total no. Of children: 45

So, as per the question, the no. Of children that attended the cricket match is 45

Answer:

They will travel 326 miles on the first day and 226 on the second day

Step-by-step explanation:

We can set up an equation to help us solve it.

Let x be the number of miles they travel on the first part of the journey

We can also write the second part in terms of x. Since it is 100 miles shorter than the first, it can be written as x-100

x+x-100=552

Add 100 to both sides

x+x=652

2x=652

x=326

They will travel 326 miles on the first day and 226 on the second day

Answer:

first option is easiest since it involves just adding both equations term by term.

3m+n=71

2m-n=30

Step-by-step explanation:

The first system looks like the easiest one, because the two equations are listed already in standard form, and the variable "n" appears as positive "n" in the first equation, and as its opposite "-n" in the second equation. Therefore the elimination method works directly by adding both equations term by term (thus cancelling out completely one of the variables in the resultant/combined equation.

Answer:

Step-by-step explanation:

You wrote the formula incorrectly. It is, correctly:

[tex]N=N_0e^{-kt}[/tex]

The k has to be a negative in the formula; if it's not, the time ends up as negative, which will NEVER be the case (unfortunately, time does not go backwards).

If the skeleton contains 67% of the C-14 it contained when the bird was alive, that 67 is our "N". When the bird was alive, it contained 100% of its C-14; so[tex]N_0[/tex] is 100. We know k, e is Euler's number, and we are looking for t.

[tex]67=100e^{-.0001t}[/tex]

Begin by dividing both sides by 100 to get

[tex].67=e^{-.0001t[/tex]

To get that t out from its current exponential position, we take the natural log of both sides. We do this because 1. it's the only way to get an exponent down from that position and 2. because natural logs and e are inverses of each other; natural logs "undo" e's and e's "undo" natural logs.

[tex]ln(.67)=ln(e^{-.0001t})[/tex] Again, because e and ln undo each other:

ln(.67) = -.0001t and solve for t. Take the natural log of .67 on your calculator and get

-.4004775666 = -.0001t and

t = 4004.7 years

Answer:

a(15) = 131

Step-by-step explanation:

Explicit Arithmetic Sequence Formula: an = a1 + d(n - 1)

We are given a1 and d, so plug them in:

an = 5 + 9(n - 1)

To find the 15th term, plug 15 in for n:

a(15) = 5 + 9(15 - 1)

a(15) = 5 + 9(14)

a(15) = 5 + 126

a(15) = 131

Answer:

Step-by-step explanation:

d = 9 ----> d is common difference

[tex]a_{1} = 5\\\\[/tex] ----> first term

In arithmetic sequence, the difference between two terms is constant.

to find nth term,

[tex]a_{n} = a_{1} + (n-1)d\\\\a_{15} = 5 + 14*9\\\\ = 5 + 126\\= 131[/tex]

Answer:

3,524 corresponde al fraccionario [tex]\frac{3524}{1000}[/tex].

Entonces, 3,524 tiene la siguiente expresión:

[tex]3,524 = \frac{3524}{10^{3}}[/tex]

[tex]3,524 = \frac{3524}{1000}[/tex]

3,524 corresponde al fraccionario [tex]\frac{3524}{1000}[/tex].

Answer:

24

Step-by-step explanation:

Ok, so we see that we have 6 as a leg of the right triangle and 10 as the hypotenuse.  As we look closer, we can tell that this makes the Pythagorean triple 6, 8, 10.  6, 8, 10 is just the Pythagorean triple 3, 4, 5 but it is multiplied by 2.  So now that we know both the legs of this right triangle, we can use the area of a triangle formula (bh)/2.  6*8=48 and 48/2 = 24 which gives us our answer.

f(x) = 3 - 2x

[tex]g(x) = \frac{1}{x + 5}[/tex]

[tex](\frac{f}{g}(8) = \frac{3-2x}{\frac{1}{x+5}}[/tex]

[tex](\frac{f}{g}(8) = (3 - 2x).(x + 5)[/tex]

[tex](\frac{f}{g}(8) = 3.x + 3.5 - 2x.x - 2x.5 = 3x + 15 - 2x^2 - 10x[/tex]

[tex](\frac{f}{g}(8) = -2.8^2 - 7.8 + 15 = -2.64 - 56 + 15 = -169[/tex]

Answer:

  B.  -5/4

Step-by-step explanation:

We're going to assume that you don't mean

  y = 45x -3

which has a perpendicular line with a slope of -1/45.

Rather, we're going to assume that you mean

  y = 4/5x -3

so that the slope of the perpendicular line is -5/4.

__

Similarly, we're going to assume that the answer choices are supposed to represent fractions, so that the above slope matches choice B.

_____

If the slope of a line is m, the slope of the perpendicular line is -1/m. The reciprocal of a fraction is the fraction that has numerator and denominator swapped. -1/(4/5) = -5/4.

Answer:

m= 70

s= 40

a= 110

d= 40

Step-by-step explanation:

Angle M is equal to 70 because it is an isoleases triangle.

The 3 sides of a triangle is equal yo 180. So if angle m is 70, then 70+70 is 140. 180-140 is 40. This makes angle s= 40.

Now we have to find angle a. Angle a and 70 make a straight line. So the line is 180. 180-70 is 110. Angle a is equal to 110.

Now we have to find angle d. As I said before All the angles of a triangle equal to 180. 30+110= 140 now 180 - 140= 40. This makes angle d= 40.

Answer: B) 5

Step-by-step explanation:

3 = 9/3

9/3 < 13/3

————————

5 = 15/3

15/3 > 13/3

————————

-9 = -27/3

-27/3 < 13/3

————————

2 = 6/3

6/3 < 13/3

Answer:

144°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 10, thus

sum = 180° × 8 = 1440°

1 interior angle = 1440° ÷ 10 = 144°

Answer:

88.6647727273 cm²

Step-by-step explanation :

The perimeter of the square =(50/2)

                                               = 25 cm

∴ Side of the square = (25/4)

                                    = 6.25 cm

∴ Area of of the square = (6.25)²

                                        = 39.0625 cm²

The circumference of the circle =(50/2)

                                            = 25 cm

∴ 2πr = 25

⇒ r = 25/(22/7)(2)

Area of the circle = (22/7) { 25/(22/7)2} {25/(22/7)2}

                             = (25×25×7) / (2×2×22)

                             = 4365/88

                             = 49.6022727273 cm²

∴ Total area of the circle and the square =(49.6022727273+39.0625000000)

= 88.6647727273 cm²

Answer:

9 cm

Step-by-step explanation:

If you were to imagine this right triangle, you would find it to be a 45 - 45 - 90 triangle. Perhaps the " shorter leg " piece of information was present to trick you, considering that the legs are congruent by converse to base angle theorem.

How is this triangle a 45 - 45 - 90? In such a triangle, the legs can be posed as x cm, as the base angles are congruent ( 45 and 45 ), thus the legs of the triangle are congruent as well. The hypotenuse would be x√2, and as we can see -

If legs = x, Hypotenuse = x√2 = 9√2

Thus, the length of the other leg is 9 centimeters ( 9 cm )
