Answer:
a₃₀ = 273
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 17 and d = a₂ - a₁ = - 7 - (- 17) = - 7 + 17 = 10 , then
a₃₀ = - 17 + (29 × 10) = - 17 + 290 = 273

A woman divided her collection of 1,200 books into 10 equal parts. She gave 3 portions to her husband, 4 portions to her daughter, and the rest equally to three nieces. How many books did her daughter receive?
Answer: Her daughter received 480 books
Step-by-step explanation:
Total collection of books =1,200
Total collection of books divided into 10 equal parts =1,200/10 = 120
Number of books given to her husband= 3 portions which means
120 x 3 =360books
Number of books given to her daughter=4 portions which means
120 x 4 =480books
The remaining which equals 3 portions were given to her three nieces.

The circular stone mound in Ireland called Newgrange has a diameter of 250 feet. A passage 62 feet long leads towards the center of the mound.
Find the perpendicular distance x from the end of the passage to either side of the mound. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
it's 125 for the radius and also 125-62 = 63
so 125+63 = 188
188 * 62 = X^2
11656 = X^2
107.96 = x
108.0 = x ( to the nearest tenth )
The perpendicular distance x from the end of the passage to either side of the mound is : 107.93 feets
Diameter = 250
To obtain the perpendicular distance, x :
We use the relation : x × x = Length to either side of mound :
Mathematically ;
x × x = 62 ft × (250 - 62)
x² = 62 × 188
x² = 11656 ft²
Take the square root of both sides ;
x = √11656
x = 107.9629 ft
Hence, the perpendicular distance x from the end of the passage to either side of the mound is : 107.93 feets

What is the solution set of the inequality: 14- 3x < -1
Answer:
x>5 (Answer should have a positive sign.)Step-by-step explanation:
To solve this problem, isolate x from one side of the equation.
First, subtract by 14 from both sides.
14-3x-14<-1-14
Solve.
-3x<-15
Multiply by -1 from both sides.
(-3x)(-1)>(-15)(-1)
Solve.
3x>15
Then, you divide by 3 from both sides.
3x/3>15/3
Solve.
15/3=5
x>5
In conclusion, final answer is x>5.

decrease 784 in the ratio 3:4
Answer:
336 and 448
Step-by-step explanation:
sum the ratio
divide the actual number by the sum i.e 784÷7=122
multiply 112 by 3 and by 4
The numbers are 336 and 448 respectively.
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. The term "arithmetic" (which comes from the Greek word "arithmos," "number") often refers to the fundamental concepts in number theory, measurement, and computation (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).
As per the given data:
We have to decrease 784 in the ratio 3:4
Consider that after decreasing, the numbers are x and y.
From the given data:
(x / y) = (3 / 4)
⇒ 4x = 3y
⇒ y = (4x/3) ...(i)
also, x + y = 784
Substituting from eq (i)
x + (4x/3) = 784
(7x / 3) = 784
x = (743 × 3) / 7
x = 336
and y = 784 - 336 = 448
Hence, the numbers are 336 and 448 respectively.

Set up and solve a proportion: On average, I can answer 14 out of 21 questions correctly in a trivia game. Assuming
this situation is proportional, how many MORE questions am I likely to get correct if there are 30 questions in all?
Answer:
20
Step-by-step explanation:
Since this is a ratio problem we first plug in all that we know
14:x
21:30
Now we find a way to get from 21 to 30
The ratio 14:21 can be simplified if we divide each by 7 give us 2:3
Now we plug the new ratio in
2:x
3:30
We get from 3 to 30 by multiplying by 10 so we also multiply 2 by 10 and we get 20
