If a soccer team played 160 games and won 65% of them, how many games did they win?

Answers

The correct answer is 104 games.

You get that number by dividing 160 with a 100, to find out how large 1% is, and then you multiply it with 65 to find out how much 65% is, and the answer is 104 games.

Your record bicycle pace along a favorite trail is 16 mph. On a recent ride, you traveled the 25 mile route in a time of 90 minutes. What was your average speed? Did it break your record pace?

Answers

Remember that d = rt or distance = rate times time. You want your answer in miles per hour so convert 90 minutes to 1.5 hours. Now plug in your values:
25mi = r*1.5hrs.
r = 25/1.5 = 16.667mph.

This is greater than 16mph so you did break your record pace.

Answer:

You did break your pace. You were able to travle about .7 miles per hour faster.

Step-by-step explanation:

Speed: Distance/time

Speed: 25/90

Speed: 16.6667 miles per hour

Speed: 16.7

The sum of two numbers is 37. the greater number is 5 more than three times the lesser number. what is the lesser of the two numbers?

Answers

Hi there!

In order to solve this problem, we should first write this into expressions.

Let x = the bigger number
Let y = the smaller number

x + y = 37
x = 3y + 5

Now, we can use substitution of the system ofinequalities to solve.

We substitute the value of x into the equation.

3y + 5 + y = 37

Now, we simplify.

4y + 5 = 37
4y = 32
y = 8

So, 8 is the answer.

Hope this helps!

3y+y+=37 that’s the answer to that

The sum of 2 numbers is 16, and the sum of their squares is 146. find the 2 numbers

Answers

Step-by-step explanation:

x + y = 16 (*)

x^2 + y^2 = 146 (**)

(*) <=> x= 16-y

substitute x = 16 - y

(**) <=> (16-y)^2 + y^2 = 146

<=> y^2 - 2.16.y + 16^2 + y^2 = 146

<=> 2y^2 - 32y + 110 = 0

<=> y^2 - 16y + 55 = 0

<=> (y-11)(y-5) = 0

<=> y=11 or y= 5

For y = 11, we have x= 16-11=5

For y=5, we have x= 16-5=11

Answer: (x,y) = (11,5) ; (5,11)

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The number of smokedetectors to be purchased.

= 12

Store A:
Cost of one smokedetector = $17

Cost of 12 smokedetectors.

= 12 x 17

= $204

Store B:

Cost of one smokedetector = $24

Cost of 12 smokedetectors.

= 12 x 24

= $288

Now,

The difference between the cost of 12 smokedetectors from store A to store B.

= $288 - $204

= $84

Thus,

The amountlessspend by buying in store Athan in store B is $84

Answer:

$84

Step-by-step explanation:

so for store A, you would do $17*12 smoke detectors, Which would give you $204. For store B you would do $24*12 smoke detectors. That is $288. Now all you do is 288-204=84. You would save $84 dollars going to store A
