4x = 20 min
7x = y min

x = 20 / 4
x = 5 min

Answer:

The instructor recommended cardio minutes for 20 minutes of strength are:

  • <u>35 minutes</u>.

Step-by-step explanation:

You must identify the following proportions within the text:

  • 7 minutes of cardio = 4 minutes of strength
  • X = 20 minutes of strenght

With the given data, a simple rule of three can be performed as shown below:

  • X = (20 * 7) / 4
  • X = 140/4
  • <u>X = 35 </u>

So it can be seen that <u>the answer is 35 minutes</u>, another way to identify it that the force time became 5 times greater than in the first case (20 is five times greater than 4), therefore, it is logical that the cardio minutes have been multiplied proportionally (7 * 5 = 35).

Li Wei has several streams of income, as shown in the table. Some streams are active income and some are passive.
WARRIOR [948]

Based on the streams of income that Li Wei has, we can calculate that he has a total passive income of <u>$3,010.</u>

Passive income refers to income that is made without a person actively involving themselves in the activity generating the income.

In this scenario, the passive income sources are:

  • Stock dividends
  • Business investment interest
  • Royalties from a novel

Total passive income therefore is:

= 530 + 1,080 + 1,400

= $3,010

In conclusion, the total passive income is $3,010.

WILL GIVE BRAINLEST!!! solve the triangle and answers to the nearest tenth.
sineoko [7]

Answer:

Angle A is 29 degress Angle B is 61 Angle C is 90

Side AB is 5.8 Side BC is 2.8 and  Side AC is 5.1

Step-by-step explanation:

Angle A is found using triangle interior theorem.

I found side AC by using law of sines

b/sin b= c/sin c

x/sin 61= 5.8/sin 90( which equal 1)

x=5.1

I found side BC by using pythagoren theorem.

a^2 + b^2=c^2

5.1^2+ b^2=5.8^2

26.01+b^2=36.64

b^2=7.63

b=approx 2.8.
