In a G.P the 3rd term is 4 times the 1st term and the sum of the 2nd term and the 4th term is 30.find the common ratio,find the sum of the first 7 terms
Answer:
the common ratio is either 2 or -2.
the sum of the first 7 terms is then either 765 or 255
Step-by-step explanation:
a geometric sequence or series of progression (these are the most common names for the same thing) means that every new term of the sequence is created by multiplying the previous term by a constant factor which is called the common ratio.
so,
a1
a2 = a1×f
a3 = a2×f = a1×f²
a4 = a3×f = a1×f³
the problem description here tells us
a3 = 4×a1
and from above we know a3 = a1×f².
so, f² = 4
and therefore the common ratio = f = 2 or -2 (we need to keep that in mind).
again, the problem description tells us
a2 + a4 = 30
a1×f + a1×f³ = 30
for f = 2
a1×2 + a1×2³ = 30
2a1 + 8a1 = 30
10a1 = 30
a1 = 3
for f = -2
a1×-2 + a1×(-2)³ = 30
-10a1 = 30
a1 = -3
the sum of the first n terms of a geometric sequence is
sn = a1×(1 - f^(n+1))/(1-f) for f <>1
so, for f = 2
s7 = 3×(1 - 2⁸)/(1-2) = 3×-255/-1 = 3×255 = 765
for f = -2
s7 = -3×(1 - (-2)⁸)/(1 - -2) = -3×(1-256)/3 = -3×-255/3 =
= -1×-255 = 255
A group of 9 people are ordering pizza. Each person wants 3 slices and each pizza has 8 slices. How many pizzas should they order?
Answer:
its 4 pizzas
Step-by-step explanation:
The number of pizzas will be a whole quantity. Then the number of pizzas ordered will be 4.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
A group of 9 people are ordering pizza. Each person wants 3 slices and each pizza has 8 slices.
The total number of slices will be given as,
⇒ 9 x 3
⇒ 27
Then the number of pizzas will be given as,
⇒ 27 / 8
⇒ 3.375
The number of pizzas will be a whole quantity. Then the number of pizzas ordered will be 4.

Tammy made $177 for 9 hours of work.
At the same rate, how many hours would she have to work to make $133?
THIS SHOULD BE EASY!!!!!
Answer:
7 hours
Step-by-step explanation:
If you divide
171 ÷ 9
you find the $ Tammy made in 1 hour.
171 ÷ 9 = 19
So Tammy made 19 for 1 hour of work.
Then we divide 133 by 19 to find out for how many hours she has to work.
133 ÷ 19.67 = 7. So Tammy has to work 7 hours to make $133.

1.) the length of a rectangular Garden is double of its breadth.if the area of Garden is 128m2.find the length and breadth
Area = Length X width
Let the width (breadth) = X
The length is double so it is 2x
Area = X * 2x = 2x^2
128 = 2x^2
Divide both sides by 2:
64 = x^2
take the square root of both sides:
x = 8
The breadth = 8 meters
The length = 16 meters

Please help me solve these 3 questions
1. To solve algebra equations using the distributive property, we need to distribute (or multiply) the number with each term in the expression. In that way, the brackets are removed. We can then combine like terms and solve by equations when necessary.
2. The first step is simply to apply the distribution using the distributive property : 3(3x-5x)+2=-8 applying the distributive operation we get 9x -15x or we could have simply done 3(2x)+2=-8 which gives us 6x+2=-8 and finally 6x= -8/2= -4
6x=-4 means x= -4/6 thus x= -2/3
3. Multiplication has priority over addition or subtraction thus we have first to apply the distributivity before combining the variable terms

When you toss a die while playing a game, you can get 1, 2, 3, 4, 5, or 6 on the top face. How many possible combinations of the top faces for the dice are there if:
a) you must toss 4 dice
b) you must toss n dice
Using the fundamental counting theorem, it is found that:
a) 1296 combinations are possible.
b) [tex]6^n[/tex] combinations are possible.
The fundamental counting theorem states that for n independents trials, each with [tex]n_1, n_2, n_n[/tex] ways of being done, the total number of combinations is:
[tex]T = n_1 \times n_2 \times ... \times n_n[/tex]
Item a:
Four independent dice throws, each with six outcomes, thus:
[tex]T = 6 \times 6 \times 6 \times 6 = 6^4 = 1296[/tex]
Item b:
n independent dice throws, each with six outcomes, thus:
[tex]T = 6^n[/tex]
