Find the values of x and y.

An inequality that expresses the mean number of steps that Diego needs to walk during the last 3 days of this week to more than 70,000 steps is  32076+3x>70000.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, Diego's goal is to walk more than 70,000 steps this week.

a) The mean number of steps that Diego walked during the first 4 days of this week is 8019.

So, the number of steps =4×8019

= 32076

Let x be the mean number of steps that Diego needs to walk during the last 3 days of this week to walk more than 70,000 steps.

Now, the inequality is 32076+3x>70000

b) The mean number of steps that Diego needs to walk during the last 3 days of this week is 12642

Substitute x=12642 in the inequality 32076+3x>70000, we get

32076+37926>70000

70002>70000

Yes, Diego will reach his goal of walking more than 70,000 steps this week.

Therefore, the inequality to represent the given situation is 32076+3x>70000.

he used the restroom starting at 4:15, he sat on the toilet and watched tt for exactly 14 minutes, He then whiped himself which took about 50 seconds. Flushing the toilet took 10 seconds and when he flushed it was 4:30.

On solving the question as said we get to know that the maximum possible length of the repeating section of the decimal representation of the given number is 10.

As 941 and 1549 are already in whole number lets assume that the question says to find the decimal repetition is 941 and 15  divided by 41 and 59 respectively.

9 divided by 41 is equal to 0.2195121951

15 divided by 49 is equal to 0.306122449.

Therefore, the maximum possible length for their repeating section is 10.

The preferred method for representing both integer and non-integer numbers is the decimal numeral system, often known as the base-ten positional numeral system and denary.

After solving the equation, the value of y obtained is equal to 10°.

An angle results from the intersection of two lines at a point. The term "angle" describes the width of the "gap" that exists between these two rays. It's represented by the symbol ∠.

Angles are most frequently measured in degrees and radians, a measurement of roundness or rotation. Angles are a part of everyday existence.

As per the information obtained from the given figure,

Angle, C = 4y

Angle, E = 180 - 116 = 64 and,

Angle, D = 7y + 6

As we know, the sum of the angles of a triangle is 180°.

Then,

4y + 64 + 7y + 6 = 180

11y = 180 - 70

11y = 110

Answer: hope it helps

Step-by-step explanation:

2^6=64≡ -1 ( mod 13)

So 2^70=16*(2^6)^11=16*(-)^11(mod 13)

2^70 ≡-16 ( mod 13)

2^70 ≡10 ( mod 13)

Now 3^3=27≡1 ( mod 13)

So 3^70= 3*(3^3)^23≡ 3*(1)^23 ( mod 13)

≡ 3 ( mod 13)

Thus 2^70+3^70 ≡ 10+3 (mod 13)

(a) 794g of the initial sample will be left in the sample after 25 years. (b) Time taken to decay to half of its original amount is 3.39 years.

Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties. Isotopes can be stable, meaning that they do not undergo radioactive decay, or they can be unstable, meaning that they will undergo radioactive decay over time.

(a) Substituting 25 for t in the expression, we get:

[tex]A(25) = 200e^{0.0541 \times 25}[/tex]

         [tex]= 200e^{1.3525}[/tex]

Thus, after 25 years, there will be

[tex]200e^{1.3525} = 2003.97[/tex]

794 g of the initial sample left in the sample.

(b) We want to find t such that

[tex]A(t) = 200e^{0.0541}[/tex]                                          

       = 100.

Solving for t, we get:

[tex]= 200e^{0.0541} \times t=100[/tex]

Dividing both sides by 200 and applying the natural logarithm to both sides, we get:

0.0541 × t = ln(0.5)

Therefore,

[tex]t = \frac{ln(0.5)}{0.0541}[/tex]

Answer: To find out how many seconds it will take for the egg to hit the ground, we need to find the value of x when the height of the egg is 0 feet. We can do this by setting the height of the egg equal to 0 in the equation 27 - 16x^2 and solving for x.

The equation for the height of the egg in feet x seconds after being dropped is given as:

27 - 16x^2 = 0

Subtracting 27 from both sides of the equation gives us:

-16x^2 = -27

Dividing both sides of the equation by -16 gives us:

x^2 = 27/16

Taking the square root of both sides of the equation gives us:

x = sqrt(27/16)

Plugging this value into the equation for the height of the egg gives us:

27 - 16(sqrt(27/16))^2 = 0

Simplifying this equation gives us:

27 - 16(27/16) = 0

Which simplifies to:

27 - 27 = 0

This equation is true, so the value of x that we found is a solution to the equation. This means that the egg will hit the ground after sqrt(27/16) seconds.

The solutions to the quadratic linear system equations are (11, 41) and (3, 9).

The given equations are y=x²-10x+30 and y=4x-3.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, y=x²-10x+30 -------(I) and y=4x-3 -------(II)

Substitute equation (II) in the equation (I), we get

4x-3=x²-10x+30

⇒ x²-10x+30-4x+3=0

⇒ x²-14x+33=0

⇒ x²-11x-3x+33=0

⇒ x(x-11)-3(x-11)=0

⇒ (x-11)(x-3)=0

⇒ x=11 and x=3

Answer: No, 2/4 is not greater than 2/3

Step-by-step explanation: To find an easy way to calculate their values we have 2 options. So, the 1st option is to turn them into a decimal. I already calculated their values which are:

2/4 = 0.5

2/3 = 0.667

Then, we compare the two decimal numbers to get the answer.

0.5 is not greater than 0.667.

The 2nd way is to find a common denominator, which would look like this:

2/4 =  6/12

2/3 =  8/12

8/12 is greater than 6/12, so that also proves that 2/4 is not greater than 2/3.
