julia-pushkina [17]

Answer:

The value of t is 1.75 years.

Step-by-step explanation:

Given that simple interest formula is I = (P×R×T)/100. So you have to substitute the following values into the formula :

$i = \frac{prt}{100}$

$let \: i = 350,p = 2400,r = \frac{25}{3}$

$350 = \frac{2400 \times \frac{25}{3} \times t }{100}$

$350 = \frac{20000t}{100}$

$350 \times 100 = 20000t$

$20000t = 35000$

$t = 35000 \div 20000$

$t = 35 \div 20$

$t = 1.75 \: years$

A rectangular park, 90 meters by 60 meters, is to be built on a city block having an area of 9000 m^2. A uniform strip borders a

stealth61 [152]

Answer:

x = 10.52 m

Step-by-step explanation:

Given that,

Length of a park = 90 m

Width of a park = 60 m

Area, A = 9000 m²

A uniform strip borders all four sides of the park for parking. We need to find the width of the strip. Let it is x. Now the area becomes,

(90+2x)(60+2x) = 9000

$4x^2 +120x +180x =5400 = 9000\\\\x=10.52\ m$

So, the width of the strip is equal to 10.52 m.

Look at the graph and tell me why it is proportional or nonproportional and why?

andreyandreev [35.5K]

Answer:

I think it is not proportional because the line is supposed to go thro the middle of each dot, and some of the dots don't have a line thro the middle only on the side or not even on the dot.

Hope this helps!

See picture below. What is the difference between 4∑n=1 2n+1 and 4∑i=1 (2i+1)?

kondor19780726 [428]

Answer:

Step-by-step explanation:

$\sum 2n+1= \boxed{\big( \sum_{i=1} ^{4}2n \big) +1}$

And,

$ \sum (2i+1)= \sum (2i)+ \sum_{i=1} ^{4} (1) $

$=\sum_{i=1} ^{4}(2i) + 1+1+1+1 $

$=\boxed{\Big(\sum_{n=1} ^{4}(2n)\Big) +4}.... \text{Variable in Summation doesn't matter}$

Hence the difference is 3.
