Answer:

formula for finding the perimeter of a triangle is A+B+C simply if the angles are equal

Answer:

Step-by-step explanation:

You are trying to find the value of K, so to do that you need to get k by itself (example : K= 3-5 instead of K+5= 3)

So in 1a i would simplify 7k-3k= 4k

then 4k=11

now to get rid of the 4 and get the k alone- you DIVIDE 4k by 4 and divide 11 by 4 cause you need to do it on both sides of the equation, it should look like this.

4k= 11

-   =  -

4      4

(4k over 4 and 11 over four)

so the answer is k = 2.75  cause 11/4 = 2.75

Answer:

NO it is not possible

Step-by-step explanation:

It is  not possible to determine from the confidence bound whether p < 0.01 and this is because since the 50.03 is less than 98% lower confidence bound which is 50.1 N , we  know that p value < 0.03 but  P value might be ≥ 0.01 . hence we cannot determine from the confidence bound whether p < 0.01

Answer:

Given:

50 plays

31/50 are comedies or tragedies

19/50 are histories.

If one is selected at random,

the chances decrease dramatically,

so :

19/50 * 19/50 = 361/2500 = .1444

Less than .2 percent.

Answer:

  5 1/2

Step-by-step explanation:

You can use the distributive property to eliminate parentheses, then add the terms that result.

  5(3/5 +1/2) = 5(3/5) +5(1/2) = 3 + 5/2 = 3 + 2 1/2 = 5 1/2

__

Or, you can add the numbers, then multiply by 5. This is the way the evaluation should be done according to the Order of Operations.

  5(3/5 +1/2) = 5(6/10 + 5/10) = 5(11/10) = 11/2 = 5 1/2

Answer:

5 1/2.

Step-by-step explanation:

5*(3/5+1/2)

= 5 * (6/10 + 5/10)

= 5 * 11/10

= 55/10

= 5 1/2.

range is what crosses the y-axis

domain is what crosses the x-axis

The number of visits Nolan can make to earn his first free movie ticket is 8.

The inequality that represents the information in the question is: 20 + 2.5x ≥ 40.

Where x represents the number of visits to the movie theater.

In order to determine the value of x, take the following steps combine similar terms

2.5x  ≥40 - 20

Answer:

Shaded area is 392

Step-by-step explanation:

The triangles on the left have heights 14 and 14, the ones on the right have 20 and 8.

The bases are equal, so we can compute them as (40-12)/2 = 28/2 = 14

The triangles have areas:

14*14/2 = 14*7 = 98

14*14/2 = 14*7 = 98

20*14/2 = 20*7 = 140

8*14/2 = 8*7 = 56

note that the triangles on the left and the ones on the right have the same total area! That would have happened no matter what the height split was!

The total area is 98+98+140+56 = 196 + 196 = 392

The answer is A. 8, 9, 10

Answer:

A. 8, 9, 10.

Step-by-step explanation:

Consecutive numbers counting numbers which are 1 greater than the other, therefore:

x + (x + 1) + (x + 2) = 27

(x + x + x) + (1 + 2) = 27

3x + 3 = 27

–3 –3

3x = 24

÷3 ÷3

x = 8.

x = 8 → [ x + (x + 1) + (x + 2) ] =

(8) + (8 + 1) + (8 + 2) = 8 + 9 + 10

Answer:

  40 square units

Step-by-step explanation:

The area can be considered as that of two trapezoids, a rectangle, and a triangle. The total area is the sum of the areas of these.

Draw two horizontal lines, one beginning at the left-most point, and another 2 units below that. Draw a vertical line segment extending the vertical line at the top down to the first horizontal line. Now the figure is divided as described above.

The upper left trapezoid has bases of 3 and 5, and a height of 4. Its area is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(3 +5)(4) = 16

The trapezoid between the two horizontal lines has bases of 8 and 7, and a height of 2. Its area is ...

  A = (1/2)(8 +7)(2) = 15

The rectangle at upper right has a base of 2 and a height of 3. Its area is ...

  A = bh

  A = 2(3) = 6

The triangle at the bottom has a base of 3 and a height of 2. Its area is ...

  A = 1/2bh

  A = 1/2(3)(2) = 3

Then the total area of all of these pieces is ...

  Area = 16 +15 +6 +3 = 40 . . . . square units

Answer:

The population growth rate is of 1.86%.

Step-by-step explanation:

Population growth rate:

Immigration plus births subtracted by emigration and deaths.

In this question, we have that:

Birth: 14.3 per 1000

Death: 11.8 per 1000

Immigrations: 21.6 per 1000

Emigrations: 5.5 per 1000

Rate:

[tex]\frac{14.3 + 21.6 - 11.8 - 5.5}{1000} = \frac{18.6}{1000} = 0.0186[/tex]

As a percentage:

Multiply by 100%. So

0.0186*100% = 1.86%

The population growth rate is of 1.86%.

Given:

The equation is:

[tex]\dfrac{x-3}{x+2}+\dfrac{3x-3}{(x+1)(x+2)}=\dfrac{x}{x+1}-\dfrac{x-2}{x+2}[/tex]

To find:

The solution for the given equation.

Solution:

We have,

[tex]\dfrac{x-3}{x+2}+\dfrac{3x-3}{(x+1)(x+2)}=\dfrac{x}{x+1}-\dfrac{x-2}{x+2}[/tex]

Taking LCM on both sides, we get

[tex]\dfrac{(x-3)(x+1)+3x-3}{(x+1)(x+2)}=\dfrac{x(x+2)-(x+1)(x-2)}{(x+1)(x+2)}[/tex]

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

[tex]x^2+x-3x-3+3x-3=x^2+2x-(x^2-2x+x-2)[/tex]

[tex]x^2+x-6=x^2+2x-x^2+2x-x+2[/tex]

On further simplification, we get

[tex]x^2+x-6=3x+2[/tex]

[tex]x^2+x-6-3x-2=0[/tex]

[tex]x^2-2x-8=0[/tex]

Splitting the middle term, we get

[tex]x^2-4x+2x-8=0[/tex]

[tex]x(x-4)+2(x-4)=0[/tex]

[tex](x+2)(x-4)=0[/tex]

[tex]x=-2,4[/tex]

But [tex]x\neq -2[/tex] because for [tex]x=-2[/tex] the given equation is not defined.

Therefore, the only solution of the given equation is [tex]x=4[/tex].

Answer:

0.1190

Step-by-step explanation:

If z = -1.18, the total area to the left under the standard normal curve is taken from the z-distribution table attached;

P(z < - 1.18) = 0.1190

Also, to the right of z = 1.18, we have;

P(z > 1.18) = 1 - P(z < 1.18)

From the second image attached from z-table, we have;

P(z > 1.18) = 1 - 0.8810

P(z > 1.18) = 0.1190

Thus, the total area to the left of z= - 1.18 and to the right of z= 1.18 under the standard normal curve is 0.1190
