Answer 1

Answer:

see explanation

Step-by-step explanation:

(a)

Since Y is the midpoint of XZ , then

XY = YZ , that is

4a - 4 = 3a + 2 ( subtract 3a from both sides )

a - 4 = 2 ( add 4 to both sides )

a = 6

(b)

XY = 4a - 4 = 4(6) - 4 = 24 - 4 = 20

XZ = 4a - 4 + 3a + 2 = 7a - 2 = 7(6) - 2 = 42 - 2 = 40

Answer 2

Step-by-step explanation:

if if y is the mid point of the line

therefore: XY=YZ

4a-4=3a+2

collecting like terms.

4a-3a=2+4

a=6

b. XY= 4a-4

recall a=6

XY= 4(6)-4

XY=24-4

XY= 20

XZ= 4a-4+3a+2

XZ= 7a-2

and a=6

XZ= 40

The mean room temperature from Monday to Saturday is 25oC and the mean room temperature of Saturday and Sunday is 28oC. if the mean room temperature from Monday to Sunday is 26oC, find the room temperature on Saturday

Answers

Answer: 24 °C

Step-by-step explanation:

Mean = [tex]\frac{\text{Sum of n observations}}{n}[/tex]

Given:  Mean room temperature from Monday to Saturday = 25°C

Sum of temperature from Monday to Saturday = 6 x  25°C   [Total 6 days from Monday to Saturday]

=  150°C

Mean room temperature of Saturday and Sunday = 28°C

Sum of temperature of Saturday and Sunday = 2 x28°C

=56 °C

Sum of temperature from Monday to Sunday = 7 x 26°C

= 182 °C

Room temperature on Saturday =  150°C  + 56 °C  - 182 °C

= 24 °C

Hence, the room temperature on Saturday = 24 °C

Find the value of $x$ for the right triangle. A right triangle with base labeled x and hypotenuse labeled 12 units. Angle between the height and hypotenuse is labeled 30 degrees. $x=$

Answers

Answer:

6 feets

Step-by-step explanation:

The triangle described in the question has been sketched in the picture attached below :

From the triangle, we could solve for X, which is the base of the triangle using trigonometry :

Sinθ = opposite / hypotenus

Sin 30° = x / 12

0.5 = x / 12

x = 12 * 0.5

x = 6 feets

Hence base, x = 6 feets

Step-by-step explanation:

Finding the Sale Price:

Sale price = 100% - 35% = 65%

Sale price = 0.65(475) = 308.75

Finding the tax:

308.75 = 100%

Tax = 5%

Sale price + tax = 105% of 308.75 or 1.05(308.75)

Total price = 324.1875

Find the sum of the predecessor of the predecessor of 2987 and successor of the greatest 3 digits number is __________

Answers

Answer:

3985

Step-by-step explanation:

Note: predecessor means a number before for example  predecessor of 4 is 3. Similarly, successor is a number after for example the successor of 4 is 5.

The  predecessor of the predecessor of 2987  = 2987-2 = 2985

Let 2985 be x

The greatest 3 digit number = 999

And the successor of the greatest 3 digits number would be = 999+1 = 1000

let 1000 be y

We have find  the sum of x and y

= 2985+1000

= 3985

b) The algebraic expression for the general term of the sequence is [tex]a(i) = 6 + 5\cdot (i - 1)[/tex].

c) The 25th term in the sequence is 126.

Step-by-step explanation:

a) Make a table of values for the sequence 6, 11, 16, 21, 26, ...

The table of values represents the ordered pairs formed by the elements of the sequence ([tex]a_{i}[/tex]) (range) and their respective indexes ([tex]i[/tex]) (domain):

[tex]i[/tex]         [tex]a_{i}[/tex]

1         6

2        11

3        16

4        21

5        26

b) Based on the table of values, we notice a constant difference between two consecutive elements of the sequence, a characteristic of arithmetic series, whose form is:

[tex]a(i) = a_{1} + r\cdot (i - 1)[/tex] (1)

Where:

[tex]a_{1}[/tex] - First element of the sequence.

[tex]r[/tex] - Arithmetic difference.

[tex]i[/tex] - Index.

If we know that [tex]a_{1} = 6[/tex] and [tex]r = 5[/tex], then the algebraic expression for the general term of the sequence is:

[tex]a(i) = 6 + 5\cdot (i - 1)[/tex]

c) If we know that [tex]a(i) = 6 + 5\cdot (i - 1)[/tex] and [tex]i = 25[/tex], then the 25th term in the sequence is:

[tex]a(25) = 6 + 5\cdot (25 - 1)[/tex]

[tex]a(25) = 126[/tex]

The 25th term in the sequence is 126.

Step-by-step explanation:

volume of a rectangle: l*w*h

the first cuboid: 7*4*2= 56

56=2*1*y

56=2y

28=y

Answer:

28cm

Step-by-step explanation:

Since the two cuboids have the same volume, we use the volume of cuboid one to find the length of side y,

Volume of a cuboid = [tex]length * breadth * height[/tex]

Volume of the cuboid with all sides given is = 7 * 4 * 2 = 56cm cubed.

Now we use that volume to calculate the length y,

56 = 1 * 2 * y

56 = 2y

y = 56/2

y = 28cm

A increased commensalism
B increased competition
C increased mutualism
D increased predation

Answers

Answer: The answer you are looking for is “B increased competition”

Step-by-step explanation: The reason why it is the answer b is when two species eat the same type of food and that said food is decreased as much as 50% there will be a lot of competition that will take place because both species want to survive so it is pretty much anyone for themselves.
