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
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

Aero had $27.88 in her account. She wrote a
check for $30.45. What will her account balance
be when the check is cashed?
When a check is cashed the amount of the check is subtracted from the balance in the account.
27.88 - 30.45 = -2.57
The balance will be -$2.57 ( negative 2.57)

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
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

Answer:
Answer is Large Jar = $30.22 and Small Jar = $8.01
Step-by-step explanation:
Formula is V = pi* r^2 * h
Large Jar.) V = 3.14 * 5^2 * 7 V = 549.5inches cubed
Small Jar.) V = 3.14 * 3^2 * 4.5 V = 127.17inches cubed
Then multiple each answer by the cents per Unit they cost
Large Jar.) 549.5 * .055 = $30.22
Small Jar.) 127.17 * .063 = $8.01

A line is perpendicular to y=-1/2x-1 and intersects the point (6, 9). What is the equation of this perpendicular line?
Answer:
y = 2x - 3
Step-by-step explanation:
slope of perpendicular line must be 2
use (6,9) and slope of 2 to find 'b', or the y-intercept
9 = 2(6)+b
9 = 12 + b
-3 = b
y = 2x - 3
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. $x=$
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

Answer:
$324.19
Step-by-step explanation:
Finding the Sale Price:
475 = 100%
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
Rounded = $324.19
Price = $324.19

Answer:
8: 190 yd , 9: 30 m, 10: 92 ft
Step-by-step explanation:
for 8, you can spit it up pretty simply. find 10x18 which is 180 and then 5x2 which is 10 so 8 is 190.
for 9, 2x8=18 for the top portion and for the sides 3x2=6, so twelve. Combined its 30m.
for 10, 10x8=80, then 6x2=12. so 92 ft combined.

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

Answer:
a) 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) 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.

Answer:
Given : length of FG = 4.3 ft
angle GFH = 52°
so we know cos theta = Base/ Hypotenuse
and here cos52° = x / 4.3
=> 0.61566147532 = x/4.3 [ as cos52° = 0.6156614]
=> 2.6445 = x
So the value of x = 2.6445 ~ 2.7 ft(ans)

It's an angles question. I keep getting 14 degrees. How do you do it?
Answer:
32
Step-by-step explanation:
By linear pair and exterior angle theorem:
[tex]x \degree + (180 - 99) \degree = 113 \degree \\ \\ x \degree + 81 \degree = 113 \degree \\ \\ x \degree = 113 \degree - 81 \degree \\ \\ x \degree = 32 \degree \\ \\ x = 32[/tex]

Answer:

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 cube with an edge length of 4 must be filled completely. How many cubic centimeters will be needed
Answer: [tex]64\ cm^3[/tex]
Step-by-step explanation:
Given
The edge length of the cube is 4 cm
If it is to be filled, then the entire volume of the cube is needed
The volume of the cube [tex](\text{edge length})^2[/tex]
[tex]\Rightarrow V=4^3\\\Rightarrow V=4\times 4\times 4\\\Rightarrow V=64\ cm^3[/tex]
Thus, 64 cubic centimeters is required.

Increased dumping of sewage into a river caused an increase in parasites that attacked the local fish population. Turtles and birds that live in the same community eat the fish. What would happen between the turtles and birds if the fish population decreased by 50% as a result of the parasitism? *
A increased commensalism
B increased competition
C increased mutualism
D increased predation
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.
