Answer:

The investors are: -3, -1 and 1

Step-by-step explanation:

Given

Three consecutive odd numbers

[tex]Sum = -3[/tex]

Required: Determine the odd numbers

Let the smallest be x. So, the other 2 are: x + 2 and x + 4.

The sum is then:

[tex]Sum = x + x + 2 + x +4[/tex]

[tex]Sum = 3x +6[/tex]

[tex]3x +6 = -3[/tex]

Collect Like Terms

[tex]3x = -3-6[/tex]

[tex]3x = -9[/tex]

[tex]x=-3[/tex]

The other two are:

[tex]x + 2 = -3 + 2 = -1[/tex]

[tex]x + 4 = -3 + 4 = 1[/tex]

Hence, the investors are: -3, -1 and 1

Answer:

x = 12 degrees

Step-by-step explanation:

They all have to add up to 360, so:

[tex]5x + 4 + 4x+9+7x+4+9x-6+4x+1=360\\29x + 12 = 360\\29x = 348\\x = 12[/tex]

Answer:

X = 49

Step-by-step explanation:

The top angle that measures 126° is a mirrored version of the angle measuring  (x + 77)°. The means the angle, (x + 77)°, has to measure 126°. So, to get x you have to subtract 126 by 77 and that gives you 49.

Answer: 14.967

Step-by-step explanation:

Use Pythagorean Theorem to find the missing length.  

a² + b² = c²        

x² + 10² = 18²      

x² + 100 = 324         [Subtract 100 from both side]  

          x²= 224        

      √x² = √224     [solve the square root from both sides]

        x   ≈  14.967

Answer:

[tex]Probability = \frac{1}{11}[/tex]

Step-by-step explanation:

Given

Marbles = 12

Selection without replacement

Required

Determine the probability of selecting 2 primes

Between 1 and 12, the prime digits is 4, and they are: 3, 5, 7 and 11

So, when the first marble is picked, the probability that it will be prime is:

[tex]P(First) = \frac{4}{12}[/tex]

Now there are 3 primes left and 11 marbles in total. So, the probability of selecting another prime is:

[tex]P(Second) = \frac{3}{11}[/tex]

The required probability is:

[tex]Probability = P(First) * P(Second)[/tex]

[tex]Probability = \frac{4}{12} * \frac{3}{11}[/tex]

[tex]Probability = \frac{1}{11}[/tex]

Answer:

=42t+16

Step-by-step explanation:

=2t+(4)(4)+(4)(10t)

=2t+16+40t

=2t+16+40t

=(2t+40t)+(16)

=42t+16

Simplify the expression

2t + 4(4 + 10t)

Simplifying

y = 2t4 + -10t2 + 13

Reorder the terms:

y = 13 + -10t2 + 2t4

Solving

Solving for variy = 13 + -10t2 + 2t4

able 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying

y = 13 + -10t2 + 2t4

Hence the information I've given you, we can now state that the answer is

42 t  +  16

Answer:

0.45 = 45% probability that the member uses the golf course but not the tennis courts

Step-by-step explanation:

I am going to solve this question using the events as Venn sets.

I am going to say that:

Event A: Uses the golf courses.

Event B: Uses the tennis courts.

5% use neither of these facilities.

This means that [tex]P(A \cup B) = 1 - 0.05 = 0.95[/tex]

75% use the golf course, 50% use the tennis courts

This means, respectively, by:

[tex]P(A) = 0.75, P(B) = 0.5[/tex]

Probability that a member uses both:

This is [tex]P(A \cap B)[/tex]. We have that:

[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]

So

[tex]P(A \cap B) = 0.75 + 0.5 - 0.95 = 0.3[/tex]

What is the probability that the member uses the golf course but not the tennis courts?

This is [tex]P(A - B)[/tex], which is given by:

[tex]P(A - B) = P(A) - P(A \cap B)[/tex]

So

[tex]P(A - B) = 0.75 - 0.3 = 0.45[/tex]

0.45 = 45% probability that the member uses the golf course but not the tennis courts

Answer: 98.1%

Explanation:

A 10% sale means that the post-sale price of the item is now 90%, or 0.9 of the original cost of the item. We then apply 9% sales tax by multiplying the 0.9 by 109%, or 1.09. 0.9 * 1.09 = .981, so the total cost of the item is 98.1% of the original pre-sale sticker price.

For percentage problems that do not deal with a specific starting number, it is always helpful to plug in 100 for the starting number. Here, we would then have a post-sale price of 90 dollars, and if we calculate the sales tax for the 90-dollar item it would be 90 * 0.09 = $8.10. THis gives us a total cost of 90 + 8.10 = $98.10, or 98.1% of the original 100-dollar price.

Answer:

Notice, period of function sin(kx) is 2π/k where k is constant (coefficient of x ) since coefficient of x in sin(2πx/3) is k=2π/3  hence the period of sin(2πx/3) is 2π/(2π/3)=3

Answer:

3/6 & 2/6

1/2 x 3, 1x3=3, 2x3=6, so it's 3/6.

1/3 x 2, 1x2=2, 3x2=6, so it's 2/6.

Step-by-step explanation:  

1 and 3/4 miles               ???? miles

--------------------  = ---------------------

2 and 1/3 minutes         39 minutes

Cross multiplies:

(1 and 3/4) x 39 =   (2 and 1/3)  x    ?

7/4 x 39/1   = 7/3 x ?

273/4 = 7/3 x ?

? = 273/4 * 3/7 =  39*3/4   <---- 7 x 39 = 273

                        = 117/4

                         = 29 and 1/4

---------------------------------------------------------------

1 and 3/4 miles              ?

------------------ = ------------------

2 and 1/3 min             60 min

(1 and 3/4) * 60 = (2 and 1/3) * ?

7/4*60/1 = 7/3 * ?

105 = 7/3 * ?

? = 105*3/7

 = 315/7

 =  45

Answer:

Answer

Step-by-step explanation:

if you spent 180 dollars, wguch was 90 percent of your money, you want to mark it up 10 percent. 180 x 1.10 is 198

Step-by-step explanation:

m∠B = 180° - y°

= 180° - 118°

= 62°

x° = 180° - (m∠B + z°)

x° = 180° - (62° + 107°)

x° = 180° - 169°

x° = 11°

i don't know, it was correct or no. Because i thought this question is looking for the valuable of x.
