Given:
The sequence is 25, 20, 15, 10, 5.
To find:
The ninth term of the given sequence.
Solution:
We have,
25, 20, 15, 10, 5
It is an AP because the difference between two consecutive terms are same.
Here,
First term (a) = 25
Common difference (d) = 20-25
= -5
The nth terms of an AP is
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
Putting a=25, n=9 and d=-5 to get the 9th term.
[tex]a_9=25+(9-1)(-5)[/tex]
[tex]a_9=25+(8)(-5)[/tex]
[tex]a_9=25-40[/tex]
[tex]a_9=-15[/tex]
Therefore, the ninth term of the given sequence is -15.

Step-by-step explanation:
[tex] \sqrt{121} [/tex]
Answer: 11
Step-by-step explanation:
When you do square root, you're just finding the number that can be multiplied by itself to get what's inside the √ .
So, when you do √121 , you'll get 11. You can check your answer by going backwards: multiply 11 by itself.

There are two numbers. The larger number is five more than the smaller
number. Three times the smaller number increased by the larger number
equals 147. Find the two numbers.
please help!!!! im in a test!!!!!!!!
Answer:
35.5 + 40.5
Step-by-step explanation:
smaller number = x
large number = x +5
3x + x +5 = 147
4 x +5 = 147
4x = 142
x = 35.5
x +5 = 40.5

6. The net of a rectangular prism and its dimensions are shown in the diagram.
8 in.
8 in.
2 in
2 in.
12 in.
12 in
What is the total surface area of the rectangular prism in square inches?
Answer:
272 square inches
Step-by-step explanation:
Given
[tex]l = 8[/tex] --- length
[tex]w = 2[/tex] --- width
[tex]h = 12[/tex] ---- height
Required
Determine the total surface area (SA)
This is calculated using:
[tex]SA = 2 * (lw + wh + lh)[/tex]
[tex]SA = 2 * (8*2+2*12+8*12)[/tex]
[tex]SA = 2 * 136[/tex]
[tex]SA = 272[/tex]
The total surface area is 272 square inches

please help me i will give you brainlyest(or however you spell it) ANSWER SERIOUSLY
x=11 should be the answer lmk if so
Answer:
x = 18
Step-by-step explanation:
m∠1 & m∠3 are vertical angles. By definition of vertical angles, their measurements will be the same.
It is given that:
m∠1 = 4x - 14
m∠3 = 58°
Set the two angles equal to each other:
4x - 14 = 58
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 14 to both sides of the equation:
4x - 14 (+14) = 58 (+14)
4x = 72
Next, divide 4 from both sides of the equation:
(4x)/4 = (72)/4
x = 72/4 = 18
18 is your answer for x.

A bus is going to a museum 135 miles away. The bus will travel at 30 miles per hour. How long will it take the bus to get
to the museum?
Answer:
4.5 hours
Step-by-step explanation:
distance equals rate times time, a relationship that can be solved for time:
time = distance / rate
Here the time is (135 miles) / (30 mph) = 4.5 hours
The bus requires 4.5 hours to get to the museum.
