Answer:

An hour and 45 minutes

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

The number of hours the battery will last if it loses 3/8 of its battery every hour is 1 hour 40.2 minutes.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

The battery charge left in the phone = 5/8 of its battery

The battery loses every hour = 3/8 of its battery

The number of hours the battery will last if it loses 3/8 of its battery every hour:

= 5/8 ÷3/8

= 5/8 x 8/3

= 5/3

= 1.67 hours

This means,

1 hour = 60 minutes

Multiply 1.67 on both sides.

1.67 hours = 1.67 x 60 minutes

1.67 hours = 100.2 minutes

1.67 hours = 1 hour 40.2 minutes

Thus,

The number of hours the battery will last if it loses 3/8 of its battery every hour is 1 hour 40.2 minutes.

Answer:

It's a

Step-by-step explanation:

Because inverse means opposite so they are asking for the opposite of the statement "If x is a whole number, then x = 5”

Hope this helped ✨

If x is not a whole number, then x ≠ 5 is inverse of the statement if x is a whole number, then x = 5

Two or more expressions with an Equal sign is called as Equation.

The given statement is "If x is a whole number, then x = 5". To find its inverse, we need to switch the hypothesis and the conclusion, and negate both parts of the statement.

The hypothesis is "x is a whole number", and its negation is "x is not a whole number".

The conclusion is "x = 5", and its negation is "x ≠ 5".

So, the inverse of the given statement is:

"If x is not a whole number, then x ≠ 5."

Therefore,  if x is not a whole number, then x ≠ 5 is correct answer.

Answer:

15 hamburgers were sold and 30 hotdogs were sold.

The systems of equations are x + y = 45 and 4x + 5y = 195.

Step-by-step explanation:

Let's make two equations.

x + y = 45

This represents the total of hotdogs and hamburgers sold

4x + 5y = 195

This represents the amount of money made for each food.

These are systems of equations, when you use 2 equations to solve a problem. I will use the strategy, Elimination for the following systems of equations. Anyways the goal is to multiply a number to x + y = 45 to cancel out one of the variables in 4x + 5y = 195. In other words, when we add these equations, the sum of the xs or ys will equal 0.

Let's multiply -5 to both x and y.

Now we have -5x -5y = -225 + 4x + 5y= 195

We will end up with -x = -30. This means that x = 30.

Now that we know x = 30, we can plug in 30 as x in one of the equations. I will plug in 30 into x + y = 45. 30 + y = 45.

Solve for y in 30 + y = 45, so y=15.

This means 15 hamburgers were sold and 30 hotdogs were sold.

the slope m=11

Step-by-step explanation:

(To find the slope use the equation m=[tex]\frac{y2-y1}{x2-x1}[/tex])

(16,3), where 16=x1 and 3=y1

(14,-19), where 14=x2 and -19=y2

m=[tex]\frac{y2-y1}{x2-x1}[/tex]

=[tex]\frac{-19-3}{14-16}[/tex]

Answer:

Basic Concept used:

Since D is the mid-point of EF,

ED will be equal to DF since D is in the middle of the line segment

We are given the following values for ED and DF

ED = 4x + 6  and  DF = 7x - 9

Solving for x:

Since ED = DF (D is the mid point)

4x + 6 = 7x - 9

9 + 6 = 7x - 4x

15 = 3x

x = 5

Finding the values of ED , DF  and EF:

we know that x = 5 (from the last section)

we are given the following values of the line segments:

ED = 4x + 6

DF = 7x - 9

EF (ED + DF) = (4x + 6) + (7x - 9)

Replacing x with 5 in each of these equations:

ED = 4(5) + 5 = 26

DF = 7(5) - 9 = 26

EF = (4(5) + 6) + (7(5)-9) = 26 + 26 = 52

Answer:

128 cm^3

Step-by-step explanation:

Putting (-1, -11) in given equation, we get :

-11 = a + -b + c    ....1)

Similarly putting (1, −5) and (2, −8) we get :

-5 = a + b + c      ....2)

-8 = 4a + 2b + c ....3)Adding equation of 1) and 2) we get :

2( a + c ) = -6

a + c = -3

Solving equation 1 , 2 and 3 ,we get :

a = -2 , b = 3 , c = -6

Therefore, equation of parabola is :

y = -2x² + 3x -6

Hence, this is the required solution.

Step-by-step explanation:

Simplifying

Cy + -5 = -3d + 6y

Reorder the terms:

-5 + yC = -3d + 6y

Solving

-5 + yC = -3d + 6y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-6y' to each side of the equation.

-5 + -6y + yC = -3d + 6y + -6y

Combine like terms: 6y + -6y = 0

-5 + -6y + yC = -3d + 0

-5 + -6y + yC = -3d

Add '5' to each side of the equation.

-5 + -6y + 5 + yC = 5 + -3d

Reorder the terms:

-5 + 5 + -6y + yC = 5 + -3d

Combine like terms: -5 + 5 = 0

0 + -6y + yC = 5 + -3d

-6y + yC = 5 + -3d

Reorder the terms:

-5 + 3d + -6y + yC = 5 + -3d + -5 + 3d

Reorder the terms:

-5 + 3d + -6y + yC = 5 + -5 + -3d + 3d

Combine like terms: 5 + -5 = 0

-5 + 3d + -6y + yC = 0 + -3d + 3d

-5 + 3d + -6y + yC = -3d + 3d

Combine like terms: -3d + 3d = 0

-5 + 3d + -6y + yC = 0

The solution to this equation could not be determined.

Answer:

0.2%

Step-by-step explanation:

We apply the z score formula.

This is given as:

Z score = x - μ/σ

x = Raw score = 140

μ = Population mean = 104

σ = Standard deviation = 12.5

z = 140 - 104/12.5

z = 2.88

Probability value from Z-Table:

P(x<140) = 0.99801

P(x>140) = 1 - P(x<140)

= 1 - 0.99801

= 0.0019884

Approximately = 0.0020

Converting to percent = 0.2%

Therefore, percent of the runners have heart rates above 140 is 0.2%
