Answer:
s4 = 270
18+36+72+144 = 270
-- convergent sums to a single value
Step-by-step explanation:
S4 = 270
Step-by-step explanation:
The 4th partial sum of the sequence is the sum of the first 4 terms:
S4 = a(1) + a(2) + a(3) + a(4)
Because the sequence is geometric any term can be written in terms of the previous one:
a(n) = r a(n - 1)
And more importantly in terms of the first term a(1) so that
a(2) = r a(1)
a(3) = r a(2) = r^2 a(1)
a(4) = r a (3) = r^3 a(1)
Then the 4th partial sum is
S4 = a(1) + r a(1) + r^2 a(1) + r^3 a(1)
S4 = a(1) (1 + r + r^2 + r^3)
With a a(1) = 18 and r = 2 we have
S4 = 18 (1 + 2 + 4 + 8) = 270
Therefore, the 4th partial sum is 270

a) find the length of each side of the square
b) find the area of the square
Answers
Step-by-step explanation:
what does P mean ?
I assume it is perimeter ?
what is the perimeter of a square ?
come on, there is practically nothing in math that is easier to solve.
a square has 4 equal sides.
so, to go one time around the whole square, we have to go along every one of its 4 sides (which are all of equal length).
so, when I get the perimeter number, I know this is the result of all 4 sides added together.
and how can we express having 4 times the same number ? exactly how we say it in English : 4 times the number.
therefore
P = 4 × side length
and from there we can immediately deduct
side length = P / 4 = 3/4 in
now we know how long the sides of the square are.
what is the area of the square ?
like for any rectangle the area is length×width. just that length=width, so that we end up with length×length = length².
therefore, the area is
3/4 × 3/4 = (3/4)² = 9/16 in²
this is important : a length is measured e.g. in inches (in). an area is then measured in square-inches = in²
Sue has 3 cats. Each cat eats 1 4 of a tin of cat food each day. Sue buys 4 tins of cat food. Has Sue bought enough cat food to feed her cats for 5 days? You must show how you get your answer
Answers
Answer:
3 3/4 tins of food
Step-by-step explanation:
Number of cats = 3
Quantity of food for each cat per day = 1/4 of a tin
Total tins of cat food sue bought = 4 tins
Has Sue bought enough cat food to feed her cats for 5 days?
Quantity of food 3 cats eat per day = Quantity of food for each cat per day × Number of cats
= 1/4 × 3
= 3/4 of a tin
Total Quantity of food 3 cats eat for 5 days = Quantity of food 3 cats eat per day × 5 days
= 3/4 × 5
= (3 * 5) / 4
= 15/4
= 3 3/4 tins of food
Total Quantity of food 3 cats eat for 5 days = 3 3/4 tins of food
Recall,
Total tins of cat food sue bought = 4 tins
Therefore, Sue bought enough cat food to feed her cats for 5 days

A hundred chickadees can eat 100 kg of seeds in 100 days. How many kg of seeds can 10 chickadees eat in 10 days?
Answers
Answer:
1 kg
Step-by-step explanation:
Number of chickadees = 100
Quantity of seed eaten = 100 kg
Number of days = 100
Quantity of seeds each chickadee eats per day =Number of chickadees ÷ Quantity of seed eaten ÷ Number of days
= 100 ÷ 100 ÷ 100
= 1 ÷ 100
= 0.01 kg of seed
How many kg of seeds can 10 chickadees eat in 10 days?
= Quantity of seeds each chickadee eats per day × number of chickadee × number of days
= 0.01 kg × 10 × 10
= 1 kg
10 chickadees eat 1 kg of seeds in 10 days
The height of a baseball in feet can be found by the equation -4.982 – 20t + 1000. How far has the
baseball traveled at t = 6?
Answers
Answer:
875.018
Step-by-step explanation:
To solve this, we must plug in 6 for our t value. So, we have the equation:
-4.982 - 20(6) + 1000
Following the rules of PEMDAS, we have:
-4.982 - 120 + 1000 = 875.018

These four points (called intercepts) are shown here. When you square each coordinate and add those values together, you get 1. They're the sine and cosine values of the most common acute-angle measures.a.) We seek the coordinates on the unit circle that represent an angle of 0 degrees.

Find x round your answer to the nearest integer.
Answers
Answer:
C
Step-by-step explanation:
Note that x is opposite to the given angle and we are also given the hypotenuse.
Since we have an angle and the side opposite to it and the hypotenuse, we can use the sine ratio. Recall that:
[tex]\displaystyle \sin \theta =\frac{\text{opposite}}{\text{hypotenuse}}[/tex]
The opposite side is x, the hypotenuse is 15, and the angle is 53. Substitute:
[tex]\displaystyle \sin 53^\circ = \frac{x}{15}[/tex]
Solve for x:
[tex]x=15\sin 53^\circ[/tex]

The length of a rectangular playing field is 5m longer than its width. If the perimeter of the field is 150m,find it's width
Answers
Answer:
35
Step-by-step explanation:
Make equations, l = w+5 and 2l + 2w = 150
Substitute w+5 into 2l + 2w = 150
Simplify to get 4w + 10 = 150
Subtract 10 from both sides to get 4w = 140
Divide both sides by 4 and you get 35 as width
Answer:
The width of the field is 35 meters.
Step-by-step explanation:
Recall that the perimeter of a rectangle is given by:
[tex]\displaystyle P = 2(w+\ell)[/tex]
Where w is the width and l is the length of the rectangle.
We know that the perimeter is 150 meters. Thus:
[tex]150=2(w+\ell)[/tex]
Divide both sides by two:
[tex]75=w+\ell[/tex]
We are given that the length is five meters longer than the width. So:
[tex]\ell = w+5[/tex]
Substitute:
[tex]75=w+(w+5)[/tex]
Combine like terms:
[tex]75=2w+5[/tex]
Subtract five from both sides:
[tex]70=2w[/tex]
And divide both sides by two. Hence:
[tex]w=35[/tex]
Thus, the width of the rectangular field is 35 meters.
The marked price of a radio was 40% above the cost price. When it was sold allowing 30% discount on it, there was loss of RS. 100. What was the marked price of the radio.
Answers
Answer:
7000
Step-by-step explanation:
70/100 * marked price = original price - 100
marked price = 140/100* og price
70/100 * 140/100 * og price = original price - 100
49/50 * og price = orignal price - 100
1/50 of original price = 100
orignal price = 5000
marked price = 140/100 * 5000 = 7000
