Step-by-step explanation:

2 \times \frac{6}{10}  =  \frac{91}{x}

\frac{26}{10}  =  \frac{91}{x}

\frac{13}{5}  =  \frac{91}{x}

13x = (91 \times 5)

13x  = 455

x =  \frac{455}{13}

x = 35

A total of $32,000 is invested in two municipal bonds that pay 4.25% and 6.25% simple interest. The investor wants an annual int
Aleks04 [339]

Answer:

$16000 invested in 4.25%  and 16000 invested in 6.25%

Step-by-step explanation:

Let x be the amount invested in 4.25%  and y be the amount invested in 6.25%

4.25%= 0.0425

6.25%= 0.0625

x+y= 32000

subtract x from both sides

y= 32000-x

total interest earned is 1680

0.0425x+0.0625y=1680

0.0425x+0.0625(32000-x)=1680

Now solve for x  and y

0.0425x+2000-0.0625x=1680

subtract 2000 from both sides

-0.02x=1680-2000

-0.02x=-320

divide by -0.02 from both sides

x=16000

y= 32000-x

y= 32000-16000=16000

Molodets [167]

Answer: Nick needs a cover that has a length of 24 feet.

Step-by-step explanation:

In order for Nick to be able to buy a proper cover for his pool for the winter months, he needs to find out the length of the pool based on the information he has about its dimensions. Nick knows that the pool is 384 square feet, and that the pool is 16 feet wide. That means that Nick needs to find out the length of the pool.

Nick has to do a very simple thing, he needs to divide the square meters of the pool with its width in order to get to its length:

384 / 16 = 24

So it turns out that the pool is 24 feet long, which means Nick has to buy a cover that will be at least 24 feet long and 16 feet wide in order to cover all of the pool.

Marrrta [24]

Answer:

21 meters

Step-by-step explanation:

Using the concept of similar triangles :

Taking the ratio of similar sides :

h/17 = 63 /51

Cross multiply :

h * 51 = 17 * 63

51 * h = 1071

Divide both sides by 51

(51 * h) / 51 = 1071 / 51

h = 21

Hence height of statue = 21 meters
