the answer is 1/13 ². Because if you divide 1/169 and 1/13, then you get 1/13. With that being said, if you multiply 1/13 and 1/13, then you get 1/169. And of course the symbol ( ² ) means squared so you multiply that number he (² ) is over twice. So like 3², 3*3=9.

Evaluate the series 4 – 2 + 1 – 0.5 + 0.25 to S10. Round to the nearest hundredth.

aleksklad [387]

The initial term of this geometric series is 4, and the common ratio is -1/2. The sum is given by

$S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}\\\\S_{10}=4\cdot \dfrac{(-\frac{1}{2})^{10}-1}{-\frac{1}{2}-1}=4\cdot \dfrac{(\frac{1}{1024}-1)}{(-\frac{3}{2})}\\\\=\dfrac{8}{3}\cdot \dfrac{1023}{1024}=\dfrac{341}{128}$

The sum is approximately 2.66.

It takes 50 oz of grass seed to seed 3000 ft2 of lawn. At this rate, how much would be needed for 7200 ft2 of lawn?

saw5 [17]

Answer:

120 ounces

Step-by-step explanation:

First find how many ft2 of lawn 1 once can seed.

To do this we simply divide 3000 by 50 ( because 50 ounces of grass seed can seed 3000 ft2 of lawn )

3000 / 50 = 60

So 1 ounce can seed 60ft2 of lawn

To find how many ounces would be needed to seed 7200 ft2 of lawn we would divide 7200 by the amount of lawn 1 once can seed ( which is 60ft2 )

7200/60 = 120

So 120 ounces of grass seed would be needed to seed 7200 ft2 of lawn

Answer for 5 stars answer and a heart with a comment. Please hurry!

klio [65]

Answer:

Length of the person = 1.9 m

Step-by-step explanation:

Actual length of the lorry = 9.5 m

Length of the lorry as per scale = 10 cm

Scale factor used to get the actual length of the lorry = $\frac{\text{Actual length}}{\text{Length on scale}}$

= $\frac{9.5}{10}$

= 0.95 : 1

Let the actual length of the person = x meters

Length of the person as per scale = 2 cm

Scale factor used to get the length of person is same.

Therefore, relation between the actual length of the person and scale length will be,

$\frac{x}{2}= \frac{0.95}{1}$

x = 2 × 0.95

x = 1.9 meters
