The amount May shared can be calculated using the expression 16 - 8.75B.

Asked: How much did May share with Liza so that she could buy the books and bookmarks?

Given:

Cost of the first book: Php 44.35

Cost of the second book: Php 67.50

Cost of each bookmark: Php 8.75

Total amount Liza had: Php 127.85

Operation:

We need to find the amount May shared with Liza to buy the books and bookmarks.

Number Sentence:

Let x be the amount May shared with Liza.

The total cost of the two books and B bookmarks can be represented by the equation:

44.35 + 67.50 + 8.75B = 127.85 - x

To solve for x, we rearrange the equation:

x = 127.85 - (44.35 + 67.50 + 8.75B)

x = 127.85 - 111.85 - 8.75B

x = 16 - 8.75B

Answer: The amount May shared with Liza depends on the number of bookmarks Liza wanted to buy (represented by B). The amount May shared can be calculated using the expression 16 - 8.75B.

To calculate the approximate number of square feet of turf that need to be painted for a base circle with a diameter of 3 feet, the area of a circle: A = πr²,   approximately 7.1 square feet of turf need to be painted.

Given that the diameter is 3 feet, the radius would be half of that, which is 1.5 feet. Substituting this value into the formula, we have:

A = 3.14(1.5)²

Simplifying the equation:

A = 3.14(2.25)

A ≈ 7.065

Rounding this to the nearest tenth, we get:

A ≈ 7.1 square feet

Therefore, approximately 7.1 square feet of turf need to be painted for a base circle with a diameter of 3 feet, by using the formula for the area of a circle and substituting the radius (which is half the diameter), we can calculate the approximate number of square feet required for the base circle. The rounded answer is approximately 7.1 square feet.

Answer:

Let j = number of shirts Jeff bought and s = the number of shirts Stephen bought.

a.) s + j = 15

b.) 2j - 3 = s

c.) Plug 2j -3 into the equation from question a.

2j -3 + j = 15

3j -3 = 15

3j = 18

j = 6

2j - 3 = s when j = 6

2(6) - 3 = s

s = 9

Jeff bought 6 shirts; Stephen bought 9 shirts.

d.) Jeff cost = 8.99(6) = $53.94

Stephen cost = 8.99(9) = $80.91

Answer:

Step-by-step explanation:

a) sum of angle on the straight line TRW is 180.

Given <TRS = 2x+10

<SRW = x-10

<TRS+<SRW = 180

2x+10+x-10 = 180

3x = 180

x = 180/3

x = 60°

<TRV = 180°-(2x+10)

Substitute x = 60° into the expression

<TRV = 180-(2(60)+10)

<TRV = 180-(120+10)

<TRV = 180-130

<TRV = 50°

2) From the diagram attached <MHJ= <LHK (oppositely directed angle)

Given

<MHJ= x+15

<LHK = 2x-20

Substitute the given data into the formula to get x

x+15= 2x-20

x-2x = -15-20

-x = -35

x = 35°

Next is to get the measure of <MHJ

<MHJ = x+15

<MHJ = 35+15

<MHJ = 50°

The answer to the multiple-choice question is 19%. The coefficient of multiple determination, also known as R-squared, measures the proportion of variation in the dependent variable that can be explained by the independent variables in a regression model.

In this case, if the R-squared is 0.81, it means that 81% of the variation in the dependent variable is explained by the independent variables.

To find out what percent of variation is not explained, we subtract the R-squared from 1 (or 100% in percentage terms). This is because the total variation in the dependent variable is either explained by the independent variables (R-squared) or unexplained (1 - R-squared).

So, the percent of variation that is not explained is:

1 - 0.81 = 0.19 or 19%

Therefore, the answer to the multiple-choice question is 19%.

75% of the bacteria to live for approximately 130.11 minutes

To answer your question, we'll be using the concept of standard deviation and the normal distribution.

Given that the average lifespan of bacteria in a culture is 2 hours (120 minutes) with a standard deviation of 15 minutes, we can expect at least 75% of the bacteria to live for a certain amount of time. Using the normal distribution, we can determine the corresponding z-score for the 75th percentile, which is approximately 0.674.

Now, we can apply the z-score formula:
z = (X - mean) / standard deviation

Rearrange the formula to solve for X (the time at which 75% of the bacteria will live):
X = mean + (z * standard deviation)

Plugging in the given values:
X = 120 + (0.674 * 15) ≈ 130.11 minutes

So, we can expect at least 75% of the bacteria to live for approximately 130.11 minutes.

The expression 39 ÷ (2 + 1) - 2 * (4 + 1) has a value of 3 when evaluated

From the question, we have the following parameters that can be used in our computation:

39 ÷ (2 + 1) - 2 * (4 + 1)

Evaluate the expressions in the brackets

So, we have the following representation

39 ÷ (2 + 1) - 2 * (4 + 1) = 39 ÷ 3 - 2 * 5

Evaluate the quotients of expressions

So, we have the following representation

39 ÷ (2 + 1) - 2 * (4 + 1) = 13 - 2 * 5

Evaluate the products of expressions

So, we have the following representation

39 ÷ (2 + 1) - 2 * (4 + 1) = 13 - 10

Lastly, we have

39 ÷ (2 + 1) - 2 * (4 + 1) = 3

Answer:

Step-by-step explanation:

Because there parallel

The factor is (w-2)(w-12) and the solution of the expression is  w =2 or 12

Given: 2wto power of 2 minus 16w=12w-48.

This expression can be written as 2w² - 16w = 12w-48

2w² - 16w = 12w-48

2w² - 16w-12w = -48

2w² - 28w + 48 = 0

Divide through by 2:

w² - 14w +  24 = 0

w² - 12w-2w +  24 = 0

Factorize:

(w-2)(w-12) = 0

w-2 = 0 or w-12 = 0

w =2 or 12

The equation of the parabola that has its focus at (0, -2) and directrix at y = 4 is presented as follows;

\(y = 1 - \frac{ x² }{12}\)

The focus of the parabola, obtained from a similar question posted online is (0, -2)

The given directrix is y = 4

From the definition of the directrix, we have;

(x - 0)² + (y - (-2))² = (y - 4)²

Which gives;

x² + (y + 2)² = (y - 4)²

4•y = y² - 8•y + 16 - (x² + y² - 4)

The equation of the line that passes through the point (-4,8) and has a slope of -1 is y = -x +4

What is the equation of a line?

A line's equation is a unified representation of all of the line's points. Any point on a line will satisfy the equation in its general version, which is of the type ax + by + c = 0. The slope of the line and a point on the line are the two essential elements needed to create the equation of a line.

Here, we have

point (-4,8) and slope = -1

If we have a non-vertical line that passes through any point(x₁, y₁) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

This is the required equation of a line in a point-slope form.

We know that Point-Slope Form:

y - y₁ = m(x- x₁)  

Where x₁ - x coordinate and y₁ - y coordinate

m - slope

Point (-4,8)

Then Slope m = -1

Now the equation as;

y - 8 = -1(x+4)

y  = -x -4+8

y = -x +4

Hence, the equation of the line that passes through the point (-4,8) and has a slope of -1 is; y = -x+4
