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:

51.25 grams

Step-by-step explanation:

Alright so, in this question you need to figure out what is the amount for 1 liter. We can figure this out by doing 12.5 ÷ 5.

That equals to 2.5 grams. Great, now we have figured out the amount for 1 liter. The next step is pretty self explanatory. We multiple 2.5 grams x 20.5 and that equals to 51.25 grams needed.

Mathamatical explanation:

12.5g ÷ 5L

= 2.5g

2.5g x 20.5L

= 51.25grams

I really hoped this helped you guys.

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%

   In this study, we tested the effects of NEAA-deprived diets and checkpoint inhibitor anti-PD-1 and anti-PD-L1 in colon cancer using syngeneic mouse model (Balb/c) bearing tumors of mouse colorectal cancer cell line CT-26. Three diets were tested, including a natural rodent diet Teklad ENVIGO Global 16% Protein Rodent Diet (control 1), a formulated NEAA-complete diet COMPLETE (control 2, using amino acid mix in place of protein), and a formulated NEAA-deprived diet FTN203 (treatment, using amino acid mix in place of protein). Both COMPLETE and FTN203 have the same nutritional structures, contain 17% w/w protein equivalent, and are isocaloric. After tumor size-based randomization, these diets were provided to mice ad libitum throughout the whole test. Each of these diets was used alone or combined with anti-PD-1 antibody (i.p., twice per week for 2 weeks) or anti-PD-L1 antibody (i.v., twice per week for 2 weeks).In this study, we tested the effects of NEAA-deprived diets and checkpoint inhibitor anti-PD-1 and anti-PD-L1 in colon cancer using syngeneic mouse model (Balb/c) bearing tumors of mouse colorectal cancer cell line CT-26.

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

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.

Given parameters:

  This is a word problem. To solve problems, it is best to interpret sentence by sentence;

   Six more than a number doubled;

      let the number  = y ;

      so  we have 2(y + 6)

    equal    =

     twice a  number plus three;

      let the number be Z;

           2Z + 3

The complete expression is thus;       2(y + 6) = 2Z + 3
