Answer:
[tex]a_{50}=16[/tex]
Step-by-step explanation:
Given that,
An airthmetic sequence,
261,256,251
We need to find the 50th term.
We have,
first term, a = 261
common difference = 256-261 = -5
The nth term of the AP is given by :
[tex]a_n=a+(n-1)d\\\\a_{50}=a+49d\\\\a_{50}=261+49(-5)\\\\a_{50}=16[/tex]
So, the 50th term of the sequence is 16.

Scale Factor
What scale factor was applied to the first rectangle to get the
resulting image?
Enter your answer as a decimal in the box.
Answer:
Scale factor = 2.5
Step-by-step explanation:
The scale factor that was applied = length of the resulting image ÷ length of the first rectangle
Length of resulting image = 7.5
Length for first rectangle = 3
Scale factor = 7.5/3 = 2.5
a dealer made a profit of 25% by selling a car for a 1000 naira find the cost price of the car
Given:
A dealer made a profit of 25% by selling a car for a 1000 naira.
To find:
The cost price of the car.
Solution:
Let x be the cost price of the car.
A dealer made a profit of 25% by selling a car. So, the selling price of the car is
[tex]S.P.=x+\dfrac{25}{100}x[/tex]
[tex]S.P.=x+0.25x[/tex]
[tex]S.P.=1.25x[/tex]
It is given that the selling price of the car is 1000. So,
[tex]1.25x=1000[/tex]
[tex]x=\dfrac{1000}{1.25}[/tex]
[tex]x=800[/tex]
Therefore, the cost price of the car is 800.

Answer:
12u + 6
Step-by-step explanation:
Solve the equation x = 5/3 (pie) (r^3) for r.
Answer and Step-by-step explanation:
To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.
[tex]x = \frac{5}{3} \pi r^{3}[/tex]
Multiply each side by [tex]\frac{3}{5}[/tex], then divide by [tex]\pi[/tex] (pi)
[tex]\frac{3x}{5\pi } = r^{3}[/tex]
Now, take the cubed root of both sides.
[tex]\sqrt[3]{\frac{3x}{5\pi } } = r[/tex]
^^ That is the answer.

Step-by-step explanation:
Two cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the northbound car has traveled 1 mile, and the eastbound car has traveled 4 miles. Measured in a straight line, how far apart are the two cars? If necessary, round to the nearest tenth.
Answer:
distance between two cars in a straight line = 4.12 miles
Step-by-step explanation:
The North and East make a right angle and if you make a straight line between the two cars you will make a right angled triangle.
Now we can use Pythagoras theorem to calculate the distance between two cars in a straight line.
p = 1
b = 4
h = ?
Using Pythagoras theorem
h² = p² + b²
h² = 1² + 4²
h² = 1 + 16
h² = 17
h = sqroot (17)
h = 4.12 miles
The distance between two cars is 4.12 miles.
Given that, two cars leave the same parking lot, with one heading north and the other heading east.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
The northbound car has traveled 1 mile = x=1 mile
The eastbound car has traveled 4 miles =y=4 mile
Let the distance between two cars be z
Using Pythagoras theorem, we get
z²=x²+y²
⇒ z²=1²+4²
⇒ z²=17
⇒ z=√17
⇒ z=4.12 miles
Therefore, the distance between two cars is 4.12 miles.

correct 89.6162 to two decimal places
Answer:
89.62
Step-by-step explanation:
Look at the 3rd place of decimals - this is 6 so we add one to the second place.
i tryed my best
The decimal number rounded to 2 decimal places is 89.62
Given data:
The decimal number is represented as 89.6162
To round 89.6162 to two decimal places, we look at the third decimal place.
Non-zero digits are always significant
Zeros between non-zero digits are always significant
Since the digit in the third decimal place is 6, which is greater than or equal to 5, we round up the second decimal place.
Hence, rounding 89.6162 to two decimal places, the number is 89.62

What is true about alternate exterior angles?
They sum to 180 degrees.
The are congruent.
They sum to 90 degrees.
They are non-adjacent.
They are adjacent.
9514 1404 393
Answer:
The are congruent.They are non-adjacent.Step-by-step explanation:
Where a transversal crosses parallel lines, the angles outside the parallel lines are called exterior angles. When they are on opposite sides of the transversal, they are alternate exterior angles.
Alternate exterior angles are congruent.
The share a side (the transversal, but not a vertex. So they are non-adjacent.

Additional comment
In this geometry, corresponding angles are congruent. Of course, vertical angles are always congruent. Each alternate exterior angle is a vertical angle with one that is corresponding to the other alternate exterior angle.
