The line t has a slope of the value of -3

The lines are given as

Line s and line t

The slope of line s is given as

Slope of line s = 1/3

Also, from the question;

We understand that line s and line t are perpendicular lines

The condition for perpendicular lines is represented as

The product of the slopes of the lines = -1

This means that

Slope of line s * Slope of line t = -1

This gives

1/3 * Slope of line t = -1

Divide both sides by 1/4

Slope of line t = -3

Hence, the slope is -3

Step-by-step explanation:

The unit rate for 3 ounces cost $2.73 is 0.91 dollars per ounces.

Unit rate is the ratio of two different units, with denominator as 1.

In other words, a unit rate is a rate where the second quantity is one unit , such as $28 per pound, 30 metres per hour, 15 Nigerian naira per Brazilian Real, etc.

Therefore, let's find the unit rate for 3 ounces cost $2.73.

Hence,

unit rate = cost / amount in weight

cost  = $2.73

amount in weight = 3 ounces

Therefore,

unit rate = 2.73 / 3

unit rate = 0.91 dollars per ounces

The components of a whole or group of items are represented by fractions. A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line. A fraction is a number that is a component of a whole. By breaking a whole into a number of parts, it is evaluated. For instance, the symbol for half of a complete number or item is [tex]\frac{1}{2}[/tex].

Given Data

Applying the ratio of 1-ounce strawberries to 3.2-ounces strawberries, the grams of fiber Marisol uses in the strawberries is 1.312 grams.

The ratio is the numerical relationship that two values share.

Ratios show proportional values to explain how much one variable is contained in another.

Ratios are represented using the ratio sign (:) or using percentages, decimals, or fractions.

Nutritional Facts

Strawberries            (1 ounce)  

Calories                       6.1 grams

Fat                               0.1 gram

Carbohydrates            1.25 grams

Fiber                            0.41 grams

Protein                        0.2 grams

Fiber = 1.312 grams (0.41 x 3.2)

Thus, Marisol needs 1.312 grams of fiber, given the ratio requirements.

Using the expression, 15x + 7y = 208 there were x = 12 baby dinosaurs and y = 4 adult dinosaurs.

A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

Each baby dinosaur made 15 paintings and every adult dinosaur made 7 paintings.

The total number of paintings the entire herd made is 208.

There were 3 times as many baby dinosaurs as adult dinosaurs.

Now, let x be the number of baby dinosaurs and y be the number of adult dinosaurs.

Then,

x = 3y

So,

The expression for the total number of paintings will be:

208 = 15x + 7y

208 = 15(3y) + 7y

208 = 45y + 7y

208 = 52y

y = 4

So,

x = 3y = 3(4) = 12

There were 12 baby dinosaurs and 4 adult dinosaurs.

The 38th term of the sequence is 63

The first step is to write out the parameters

The first term (a) = 211

The common difference (d) = 207 - 211

The 38th term of the sequence can be calculated as follows

a₃₈ = a + (n-1)d

a₃₈ = 211 + (38-1)(-4)

a₃₈ = 211 + 37(-4)

a₃₈ = 211 - 148

Using the LCD of 2 fractions formula, it was determined that the LCD of 11/7 and 3/8 is 33.

When two or more fractions are supplied, the least common denominator is the smallest number among all the common multiples of the denominators.

LCD of 11/7 and 3/8 is given as follows:

We know that,

LCD of 2 fractions = (LCD of a,b)/(HCF of a,b)  where a and b are two fractions.

LCD = (LCD of 11/7 and 3/8)/(HCF of 11/7 and 3/8)

       = 33/1
