If a swimmer swims 85.4 yards in 5 minutes, how many meters will he/ she swim in 70 seconds
DaniilM [7]

Distance swam in 5 minutes = 85.4 yards

Since, 1 min = 60 seconds and 1 yard = 0.91 meter

5 minutes = 5 \times 60 = 300 seconds

85.4 yards = 85.4 \times 0.91 = 77.7 meters

So, Distance swam in 300 seconds = 77.7 meters

Now, we will use unitary method to determine the distance swam in 70 seconds.

Distance swam in 1 second = 77.7 \div 300 = 0.26 meter

So, Distance swam in 70 seconds = 70 \times 0.26

= 18.2 meters

Therefore, the swimmer took 70 seconds to cover the distance of 18.2 meters.

Find the measure of angle x in the figure below:
Sergeeva-Olga [200]

Answer:

30 degrees.

Step-by-step explanation:

We are going to use two theorems: Triangle Sum Theorem and Vertical Angles Theorem. Please let me know if you need me to define them.

Here is how I solved this problem:

75+75 = 150.

180-150 = 30(Triangle Sum theorem)

x = 30(Vertical Angles theorem.)

a farmer sells his corn for $230 a metric ton with a small surcharge of $25. his neighbor sells her corn for $230 a metric ton a
anyanavicka [17]

Step-by-step explanation:

Step one:

The farmer sells his corn for $230 a metric ton

small surcharge = $25.

let the amount per metric ton be x

and let the total cost per x metric ton be y

the total cost function is

y=230x+25--------------1

The neighbor sells her corn for $230 a metric ton

he gives $15 rebate------<em>A rebate is a partial refund of the cost of an item</em>

let the amount per metric ton be x

and let the total cost per x metric ton be y

the total cost function is

y=230x-15----------------2

Step two:

Equating the two equation above

230x+25=230x-15

230x-230x=25+15

0=40

The result shows that based on the cost function of both farmer, there will never be an amount of corn that would make them have the same cost
