Answer:

Mai can make 7 bracelets. (The answer to the question is 7)

Step-by-step explanation:

We know that <em>each </em>bracelet is made from 24.3 centimeters of string. We need to find out how many bracelets can be made from 170.1 centimeters.

To solve this equation, we need to divide 170.1 by 24.3.

170.1 ÷ 24.3 = 7

Therefore, Mai can make 7 bracelets. (The answer to the question is 7)

Hope this helps! :D

two ferries start moving toward each other from opposite riverbanks, a and b. when they pass each other for the first time, the
Usimov [2.4K]

Let 'x' be the distance from THE far bank   where 700 is the distance to the NEAR bank

boat one has travelled 700    (rate = 700/unit time)         boat two has travelled   x    rate = x / unit time

boat one then travels   x  + 400  more      and boat two travels   700 + (700+x -400) more    when they meet

The time is the same      rate x time = distance      distance/rate = time     equate the distances divided by the respective rates

(700 + x + 400)/700     =    (  x  +  700     +  (700+x-400) )/x

1100x + x^2 = 1400x + 700000

x^2-300x -700000 = 0                         quadratic formula yields  x = 1000  

One boat travels 700   the other   1000 whe they first meet.....width of river =   700+ 1000 = 1700 m

In a​ poll, 22​% of 714 surveyed adults said that . What is the actual number of adults who said that
Eva8 [605]

Answer:

<h2> 157 surveyed adult </h2>

Step-by-step explanation:

IF 22% of 714 surveyed adult made a statement, the actual number of those that made the statement can be gotten by simply evaluating 22% of 714 as shown below;

= 22% of 714

= 22/100 * 714

= (22*714)/100

= 15708/100

= 157.08

≈ 157 surveyed adult

<em>This means that about 157 surveyed adults made the statement. </em>

Customers of a satellite dish company must pay for installation of the dish, and a monthly fee for service. After 6 months, Ryan
FromTheMoon [43]

Cost of installation fee is $120.

Step-by-step explanation:

Let,

Monthly fee = x

Installation fee = y

According to given statement;

6x+y=594   Eqn 1

11x+y=989   Eqn 2

Subtracting Eqn 1 from Eqn 2

(11x+y)-(6x+y)=989-594\\11x+y-6x-y=395\\5x=395\\Dividing\ both\ sides\ by\ 5\\\frac{5x}{5}=\frac{395}{5}\\x=79\\

Putting x=79 in Eqn 1

6(79)+y=594\\474+y=594\\y=594-474\\y=120

Cost of installation fee is $120.
