Answer:

11, 11

Each shirt costs $11 and each pair of pants costs $11.

without the math explanation we know they must be equal logically and also must both be 11 lmk if youd like an explanation for that

Step-by-step explanation:

s+3p=44

3s+p=44

s=44-3p

3(44-3p)+p=44

132-9p+p=44

-8p=-88

p=11

s+3(11)=44

s+33=44

s=11

Answer:

Each shirt costs $11 and each pair of pants costs $11.

Step-by-step explanation:

If 1 shirt costs $11, & a pair of pants also costs $11, I buy 1 shirt, my total is $11. Now, I buy 3 pairs of pants, 11x3 is $33, so 33+11 is $44. My total is $44.

My friend buys the 3 shirts, $33 is my friend's total. He now buys 1 shirt, which is also $11. Again, 33+11=$44

1. ∠AHB and ∠AHG are vertical angles False

When two lines intersect, the angles that face each other are called vertical angles. Instead of referring to them as being up-down, "vertical" in this context denotes that they share a vertex (corner point).

2.∠EHF and ∠DHE are adjacent angles True

When two angles have a similar vertex and side, they are referred to as neighboring angles. The vertex of an angle is the point at which the rays that make up its sides come to an end. When adjacent angles have the same vertex and side, they can be a complimentary angle or supplemental angle.

Answer:

$14.7

Step-by-step explanation:

To find the markup, you can use the following formula:

markup = (selling price - cost price) / cost price x 100

cost price = $35

selling price = $35 + markup

markup = (selling price - $35) / $35 x 100

Now you know that selling price = $35 + markup and markup = 42%, so you can use this information to find selling price:

markup = 42% = 0.42

selling price = $35 + $35*0.42 = $35+14.7 = $49.7

So the markup is $14.7

To find out what percent 567 is of 448, we can use the following formula:

What does math mean by percent?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

percent = (part / whole) x 100

where "part" is the value we are trying to find the percentage of (in this case, 567), "whole" is the total value (in this case, 448), and "percent" is the final answer.

So, we can plug in the values and get:

percent = (567 / 448) x 100

To get the percentage we need to multiply the fraction by 100

percent = 126.58%

So 567 is 126.58% of 448.

Correct option is C, Both have fixed initial rate and payment amount.

A balloon mortgage is similar to an adjustable rate mortgage (ARM) in other ways, with an initial rate period that is equal to the balloon duration. For instance, a 7-year balloon is frequently contrasted with a 7-year ARM. For 7 years, both have a set rate; after that, the rate will change.

A balloon mortgage starts off with set payments for a set amount of time and comes to a finish with a single, large payment. Because it is substantially greater than the initial instalments, the one-time payment is known as a balloon payment. According to the definition of a balloon loan, the final payment is at least twice as much as the average monthly payment on the mortgage. Balloon payments typically cost tens of thousands of dollars.

Variable-rate mortgages (VRMs), commonly referred to as adjustable-rate mortgages (ARMs), feature an interest rate that may fluctuate on a regular basis based on changes in the appropriate financial index linked to the loan. Generally speaking, if the index rate rises or falls, your monthly payment will too.

The value of this approximation will be 3.7678.

To approximate the integral of 4 1 (2x2 1) dx using a midpoint Riemann sum with 3 equal subintervals, the following calculations can be used:

Start by finding the width of each subinterval (w). Using the given bounds of integration, this can be calculated as: w = (b-a)/n, where n is the number of subintervals. In this case, w = (2-1)/3 = 0.3333.

Next, calculate the midpoint of each subinterval. This can be done by taking the average of the lower and upper bounds of each subinterval. In this case, the midpoints are 1.1667, 1.5, and 1.8333.

Finally, calculate the value of the midpoint Riemann sum by adding the product of the function evaluated at each midpoint and the width of each subinterval. This can be expressed as:

Sum = 0.3333 * [4(1.1667)2 -1] + 0.3333 * [4(1.5)2 -1] + 0.3333 * [4(1.8333)2 -1]

Sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant are the six trigonometric ratios (sec). A branch of mathematics called trigonometry in geometry deals with the sides and angles of a right-angled triangle. Trig ratios are therefore assessed in relation to sides and angles.

The trigonometric ratios (sine, cosine, and tangent) are the same for all 30-60-90 triangles because these triangles have a unique set of properties that make them special. Specifically, all 30-60-90 triangles have a right angle, and the angle measures are in a ratio of 1:2:3. Because of these properties, the length of the hypotenuse is always twice the length of the shorter leg, and the length of the longer leg is always equal to the square root of 3 times the length of the shorter leg. This allows us to determine the exact values of the trigonometric ratios for all 30-60-90 triangles, regardless of their size.

The bicycle travels 2198 cm or about 21.98 meters for 10 complete revolutions of the tires.

What is the circumference of the circle?

The distance traveled by bicycle each time the tires make one complete revolution is equal to the circumference of the tire. The circumference is given by the formula:

C = 2 * π * r

Where C is the circumference, π is approximately 3.14, and r is the radius of the tire. Since the diameter of the tire is 70 cm, the radius is half the diameter, which is 70/2 = 35 cm. So we can substitute that value into the formula to find the circumference:

C = 2 * 3.14 * 35 = 219.8 cm

So the bicycle travels 219.8 cm each time the tire makes one complete revolution. To find out how far the bicycle travels each time the tires make 10 complete revolutions, we simply multiply the distance per revolution by 10:

distance = 219.8 cm * 10 = 2198 cm

Hence, the bicycle travels 2198 cm or about 21.98 meters for 10 complete revolutions of the tires.

There are several different methods for factoring quadratics, including factoring by grouping, completing the square, difference of squares, sum and difference of cubes, synthetic division and quadratic formula.

Factoring by grouping: This method involves grouping the first two terms and the last two terms of the equation, and then factoring out a common factor.

Completing the square: This method involves changing the form of the equation so that the left side is a perfect square trinomial. This allows you to take the square root of both sides and solve for the roots.

Difference of squares: This method can be used when the equation is of the form a^2 - b^2 = 0. It can be factored as (a+b)(a-b) = 0.

Sum and difference of cubes: This method can be used when the equation is of the form a^3 + b^3 = 0 or a^3 - b^3 = 0. It can be factored as (a+b)(a^2-ab+b^2) = 0 or (a-b)(a^2+ab+b^2) = 0.

Synthetic division: This method can be used when the equation is in the form of a polynomial divided by a binomial. It uses division to factor the polynomial.

Quadratic Formula: This method can be used when factoring by grouping or completing the square seems difficult or impossible. This method uses the formula -b±√(b^2-4ac) /2a where a, b, c are the coefficient of x^2,x and constant term in the equation to find the roots of the quadratic equation.

The coordinates for the other endpoint of the line segment will be (-4,-9).

What are coordinates of a line segment?

The location of a line segment on the coordinate plane is defined by two endpoints whose coordinates are known. The line links the two endpoints but does not extend beyond them. It is a segment (piece) of a line.

This is the same as the definition of a line segment in ordinary plane geometry, the only difference being that we know the coordinates of the points involved.

Coordinates - Coordinates are the components of an ordered pair. In an ordered pair, the first number is called the x-coordinate and the second number is called the y-coordinate.

Now

Given,

One endpoint (x2,y2) having coordinates= (8,-5)

Let other endpoint be = (x1,y1)

Midpoint (x, y) = (2,-7)

Therefore,

x=(x1+x2)/2 and y=(y1+y2)/2

x1=2x-x2             y1=2y-y2

x1=4-8                 y1=-14+5

x1=-4                   y1=-9

Hence, other endpoint is (4,-9).
