The measures of two vertical angles are given by the expressions (x+16)° and (2x - 3).
Find the value of x . What is the measure of each angle?

As the given polynomial -8y has only 1 term in is and hence it is classified as a monomial.

A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables.

x² 4x + 7 is an illustration of a polynomial with a single indeterminate x.

The quantity of terms allows for the classification (naming) of polynomials.

A polynomial may contain exponents, constants, and variables, but it never divides by a variable.

They may also contain one or more terms, but not an infinite quantity.

The degree can also be used to categorize polynomials (the largest exponent of the variable).

An expression with only one term is called a monomial.

The sole term in an expression needs to be non-zero in order for it to be a monomial.

Therefore, as the given polynomial -8y has only 1 term in is and hence it is classified as a monomial.

The minimum score Sam needs to get on his final exam to get a "C" in the course is 82.

What is a probability?

A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

Given that, Sam's test scores are 62, 71, and 65.

The total score in three test is (62 + 71 + 65) = 198

Assume that, he scored x in the final test.

Total score of Sam is 198 + x.

He needs to score 70% means he needs to score 70 out of 100.

According to question,

(198 + x)/ 400 ≥ 70/100

Multiply both sides by 100:

(198 + x)/ 4 ≥ 70

Multiply both sides by 4

198 + x ≥ 280

With the help of congruency of triangles rules, we know that TSR ≅ QRS because of (B) the AAS congruence theorem.

Two triangles are said to be congruent if all three corresponding sides and all three corresponding angles have the same size.

These triangles can be moved, turned, flipped, and rotated to produce the same appearance.

When moved, they are parallel to one another.

So, we have two sets of angles and one common side.

Review the congruence situations.

SSS ⇒ Three sides in the first, three sides in the second.

SAS: two sides, including the angle of the first side.

Incorporating angle in the second.

AAS = 2 angles in the first triangle, plus 1 side.

Let's read the statements again and fill in the blanks.

Step 1: Since all right angles are congruent, mTSR = mQRS = 90°.

Step 2: Since it is given, mT = mQ

The slope of the line passing through the points  (-9, 6) and (-3, 9) is (1/2).

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is

y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

We know slope(m) = (y₂ - y₁)/(x₂ - x₁).

Given, A line passes through the points (-9, 6) and (-3, 9).

Answer:

y = 0

Step-by-step explanation:

x + 2y = 2 ( subtract 2y from both sides )

x = 2 - 2y → (1)

x = - 4y + 2 → (2)

substitute x = 2 - 2y into (2)

2 - 2y = - 4y + 2 ( add 4y to both sides )

2 + 2y = 2 ( subtract 2 from both sides )

2y = 0 , then

y = 0

What is equation of an ellipse?

The standard equation of an ellipse centered at (h, k) with a major axis parallel to the x-axis is given by:

[tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]

where the coordinates of the vertex are (h±a, 0), coordinates of co-vertex are (h, k ± b) and the coordinates of foci are (h±c, k), where a² = c² + b².

According to the given question:

Given foci of the ellipse :

(-6, -1) and (-6, -7)

Co-vertices of the ellipse :

(-2, -4) and (-10, -4)

From the given foci and vertices ,

c = -1 - (-7) /2 = 3

b = -2 - (-10) /2 = 4

c² = a² + b²

∴ a² = 3 x 3 + 4 x 4 = 25

( h, k) = (-6 - 6 /2 , -1 - 7 / 2) = (-6, -4)

Equation of the ellipse is given by:

(x - h)²/ a² + (y - k)²/b² =1

(x - (-6))²/ 25 + (y - (-4))²/16 = 1

Comparing two amounts of the same units and determining the ratio tells how much of one quantity is in the other.

when evaluating the relationship between two quantities or numbers. In general, x: y, which can be interpreted as "x is to y," is used to denote a ratio between two quantities.

Here we have

15 Cookies need 80g Oats

=> Amount of Oats for 1 cookie = 80g/15 gms

So the amount Oats for 36 Cookies = 80g/5 × 36 = 192 grams

15 Cookies need 340 grams of Maple syrup

=> Amount of Maple syrup for 1 cookie = 340/15 gram

So the amount of Maple syrup for 36 cookies = (340/15)×36 = 816 grams

By the above calculations,

For 36 Cookies we need 192 grams of Oats and 816 grams of Maple syrup

The Ratio of Oats to Maple syrup = 192 gram: 816 gram

Let 'h' be the height of the tower. Then we have

tan 37° = (h - 2) / 30

Simplify the equation, then we have

tan 37° = (h - 2) / 30

By solving an inequality, we will see that option a is cheaper for more than 60 miles.

We know that option A charges $25 per day plus $0.15 per mile, so the cost for x miles is given by the linear equation:

A(x) = $25 + $0.15*x

While for option B the fixed cost is $10 and the cost per mile is $0.40, so the cost equation is:

B(x) = $10 + $0.40*x

The cost of option a will be smaller when:

$25 + $0.15*x < $10 + $0.40*x

$25 - $10 < $0.40*x - $0.15*x

$15 < $0.25*x

$15/$0.25 < x

60 < x

So for 60 miles the cost is the same, for x > 60 miles the cost of option a will be smaller (because the slope is smaller).

x = 4y.

As given in the question,

Let us consider number of pages write by Bill be 'x'

And number of hours represented by 'y'

Number of hours used by Bill to write 4 pages = 1 hour

Number of pages written by Bill in 1 hour = 4

Given :

Number of pages is proportional to the number of hours

⇒ x ∝ y

⇒ x = ky

Where 'k' is the constant of proportionality.

When x = 4 , y = 1

substitute the value in the equation,

4 = k(1)

⇒ k = 4

Now the required equation with the constant of proportionality k = 4 is:

x = 4y

Therefore, the required equation to represent the relation between number of pages written to the number of hours used with constant of proportionality is equal to x =4y.

Therefore, coin is unfair ,It is true that the coin can be considered unfair.

Calculating or estimating how likely or "possible" something is to occur is the subject of probability. Words like "certain," "impossible," or "probable" can be used to express the likelihood of an event occurring. Probabilities in mathematics are always expressed as fractions, decimals, or percent with values ranging from 0 to 1.

Here,

Step 1: We see that a coin is tossed 100 times, but we only receive heads 27 times.

In other words, the odds of a head are 27/100 or 0.27.

It is thought that there will be an equal number of heads and tails on a fair coin (or very close, if not equal).

So, using a fair coin:

P(H)=P(T)=0.5

Step-by-step explanation:

The graph is linear, meaning it follows the formula [tex]y=mx+b[/tex], where y and x are variables, m is the constant rate that the graph increases by, and b is the y-intercept. The graph is increasing at a rate of 55 calories burned per 5 minutes spent skateboarding, which simplifies to 11 calories per 1 minute, so m is 11. The graph's y-intercept is 0 because it runs through the origin, and there's no point in writing "11x + 0" so it's just "y = 11x"
