Darren is training for a triathlon. Each week, he goes to the gym for a maximum of 20 hours. He spends at least 8 of those hours weightlifting (x). He wants to spend no more than 15 hours doing cardio exercises (y). Write a system of linear inequalities that represents the restrictions of this scenario.

Answer:

35√2

Step-by-step explanation:

[tex]5\sqrt{98}[/tex] = [tex]5\sqrt{2*49}[/tex] = 5 × √2 × √49 = 5 × 7 × √2 = 35√2

Answer: y = -5/3x + 4 and 5x + 2y = 4

Step-by-step explanation:

1. Firstly, we should substract 5x on both sides of the equation.

3y = -5x + 12

Then we divide by 3 on both sides of the equation. This would give us our answer.

y = -5/3x + 4

2. The answer is 5x + 2y = 4.

The slope of parallel lines should be the same. If we want to isolate y of the above the equation we should first substract 5x on both sides.

2y = -5x + 4

Then we should divide 2 on both sides of the equation.

y = -5/2x + 4

The equation above and y = -5/2x -7 have the same slope. Therefore, they are parallel.

Now the formula for the area of a circle is: πr². So we take 3 and just put it into the equation. π·3²=28.27. This is the area of the circle. Now the rate of change I think would just be the difference between the radius and the area of the circle so 28.27-3=25.27.

The required number of picks that will be made for the same value is 26.

Given that,
A standard deck of 52 playing cards is placed face down on a table how many cards must you draw from the deck to be certain that you will have a pair of the same value is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
A card deck consists of 52 cards, and the deck has 4 number of cards of the same number but different families, which implies the number of 4 equivalents cards in the deck is 13 (Since 52 / 4).
According to the question number of the pair is to be determined that has the same value,
Total number of pairs = 2 * 13 = 26

Thus, the required number of picks that will be made for the same value is 26.

Answer:

47/20

Step-by-step explanation:

Converting 4 7/10 into improper fraction:

((4*10)+7)/10

= (40+7)/10

= 47/10

Multiply 47/10 by 1/2

= 47/(10*2)

= 47/20

Answer:

Step-by-step explanation:

its a linear line so using the equation y=mx+c it can be determined that y=-4 when x=-2.

gradient (m) is -2 and c is -4

so that means y=-2x-4

To make a random selection using a random number generator, we could make use of a computer programming to execute the task by following the steps below ;

A.) Using python 3 to generate a random sample of 141 plots :

import random

#import the random module

random_sample = random.sample(range(1410), 141)

#using the sample method, randomly select a sample of 141 plots from the total number of plots, 1410

print(random_sample)

#display the randiy selected plots which is 10% of the total

B.) Choosing the first three plots using the method described in (A)

first_3 = random_sample[:3]

#from the 141 random samples, use list slicing to select the first three plots from the sample

print('\n The first 3 plots are : ' , first_3)

#display the first three sample plots selected.

Answer:

5+x^3

Step-by-step explanation:

The expression of 5^20 as a power of 25 can be written as 25^10.

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

We need to express 5^20 as a power of 25

If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" means this statement might change from text to text slightly.

Thus, 5^20 can be written as ;

(5^2)^10 = 25^10

Therefore, the expression of 5^20 as a power of 25 can be written as 25^10.
