If his heartbeat has increased by 8 beats per minute after 20 minutes of working out how much will his heartbeat have increased

-BARSIC- [3]

Answer:

12 beats per minute after 30minutes

Step-by-step explanation:

Since we are told by how much his heartrate increased in 20 minutes, we can simply calculate how much it increased in 10 minutes and add that amount to the current heart rate to know how much his heartrate increased after 30 minutes of working out. Since 10minutes would be half of the 20minutes we simply divide the beats per minute by 2.

8 / 2 = 4 beats per minute after 10 minutes

Now we simply add this to the beats per minute at the 20minute mark to calculate the beats per minute at 30minutes

8 + 4 = 12 beats per minute after 30minutes

JKL is similar to PQR

so they want PR

JKL is similar to PQR

So PR is similar to JL

And they also give us the sides KL and QR

JKL is similar to PQR

Both of those sides are similar, so we can form a proportion.

$\sf { \frac{PR}{JL} = \frac{QR}{KL} }$

Plug in the numbers:

$\sf { \frac{PR}{6} = \frac{15}{9} }$

Cross multiply:

$\sf{ PR \times 9 = 6 \times 15}$

Isolate PR

$\sf{ PR = \frac{6 \times 15}{9}}$

Simplify it

$\sf{ PR = 10}$

So your final answer is

$\boxed{\bf{10 centimeters}}$

lawyer [7]

Answer:

Given parameters:

Selling price of belt = $120

Percentage discount = 25%

Unknown:

Discount = ?

Sale price of the dress = ?

Solution:

Discount is a reduction in the price of a commodity.

Discount = percentage discount x selling price of belt

Input the parameters and solve;

I. Discount = $\frac{25}{100}$ x 120 = $30

II. Sale price of the dress;

= selling price - discount amount

= $120 - $30

= $90
