Which is a disadvantage of using cash as a payment method? Accepted almost everywhere. Has no fees or interest. Must hand deliver all payments. Fraud is rare except occasional counterfeiting.

Answer: 49

==============================================

Explanation:

HI is parallel to KL, so this means that the two triangles can be proven similar through the AA (angle angle) similarity theorem.

Consequently, that means we can set up the proportion below

JH/JK = HI/KL

noticed how the left slant sides JH and JK pair up together on one side; the horizontal sides HI and KL pair up on the other side. I have the larger triangle's side lengths as the numerator for each side

Plug in the given values. Solve for HI

JH/JK = HI/KL

35/15 = HI/21

7/3 = HI/21

21*7 = 3*HI

3*HI = 147

HI = 147/3

HI = 49

This means that 35/15 = HI/21 turns into 35/15 = 49/21

Note: to check the answer that the last equation mentioned is true, we can subtract the fraction 49/21 from both sides to end up with 35/15 - 49/21 = 0. If you type "35/15 - 49/21" into your calculator, you should get 0, which will help confirm we have the right answer.

Answer:

Adele's current age is 12

Step-by-step explanation:

Let a = Adele's current age

Let t = Timothy's current age

Adele is 5 years older than Timothy:

a = t + 5       {equation 1}

In 3 years Timothy will be 2/3 of Adele's age:

(2/3)(a + 3) = t + 3     {equation 2}

Since we are looking for Adele's age, let's rearrange equation 1 to:

t = a - 5

Substitute that into equation 2 and solve for a.

(2/3)(a+3) = a - 5 + 3

(2/3)(a + 3) = a - 2

Multiply through by 3 to clear the fraction

2(a+3) = 3a - 6

2a + 6 = 3a - 6

Add 6 to both sides, subtract 2a from both sides

12 = a

Adele is 12 years old

This means Timothy is 7 years old.

Check equation 2 to verify:

(2/3)(a + 3) = t + 3

(2/3)(12+3) = 7 + 3

(2/3)(15) = 10

10 = 10

Answer:

Adele is 12 years old

Answer:

$43.13

Step-by-step explanation:

The original price plus the markup = selling  price

The markup = original price * percent markup

So

selling price = original price + original price* percent markup

Factoring out the original price

selling price = original price (1+ percent markup)

Substituting what we know)

69 = original price (1+.60)

69 = original price(1.6)

Divide both sides by 1.6

69/1.6 = original price

43.125 = original price

We round money to the nearest cent

$43.13

To find the cost of the sweater to Sears, divide the selling price by 1.6.

To calculate the cost of the sweater to Sears, we need to first find the selling price. A 60% markup on the selling price means that the selling price is 160% of the cost price. Let's say the cost price of the sweater to Sears is C.

So, the selling price of the sweater is 160% of C. In equation form, this can be expressed as: 1.6C = $69.

To find the cost price, we can divide both sides of the equation by 1.6: C = $69/1.6 = $43.125.

The cost of the sweater to Sears is $43.125.

Answer:

4 muffins per cup of flour

Step-by-step explanation:

To solve this, simplify the ratio as much as possible

8 muffins : 2 cups of flour

You are solving for: x muffins : 1 cup of flour

Simplify. Divide common factors from both the numerator and denominator. In this case, divide 2.

8/2 = 4

2/2 = 1

4 muffins : 1 cups of flour is your simplified version.

4 muffins per cup of flour is your answer

The answer is: Fiona's meals are less expensive.

Answer:

a) Option b

b) 7524

Step-by-step explanation:

a) The survey is to estimate the number of adults.  Hence only adults should be surveyed and not senior citizens or houseowners. Since all adults cannot be surveyed a sample strictly at random of adults can be surveyed.  Since option b satisfies this, we select b as answer.

b) Given that in the survey of 25 adults 11 voted in the last election.

Hence out of 17100 adults, no of adults who voted in the last election would be

[tex]\frac{11}{25} *17100 = 7524[/tex]

So out of 17100, 7524 adults would have voted in the last election.

Answer:

m<S = 45°

Step-by-step explanation:

The sum of the measures of the angles of a triangle equals 180 deg.

m<R + m<S + m<T = 180

3x + 2x + 3x = 180

8x = 180

x = 22.5

m<S = 2x = 2(22.5) = 45

In an isosceles triangle, the sum of the angles must equal 180 degrees. Given the angles labeled as multiples of x, solving for x gives 22.5 degrees, and m∠S is found to be 45 degrees.

The student is asking to find the measure of angle S in an isosceles triangle with vertices labeled R, S, and T, where sides RS and ST are equal, and the angles at R and T are labeled as 3x degrees, and angle S as 2x degrees. Since the sum of angles in any triangle is always 180 degrees, we can set up an equation by adding the angles together: 3x (angle R) + 2x (angle S) + 3x (angle T) = 180. Simplifying the equation gives 8x = 180, and solving for x gives x = 180 / 8 = 22.5 degrees. Finally, to find m∠S, we substitute x back into the expression for angle S: m∠S = 2x = 2(22.5) = 45 degrees.

Answer:

= 36000 caps

Step-by-step explanation:

First we need to figure out how many minutes between 8 am and 3:30 pm

There are 7 hours and 30 minutes.

1 hour = 60 minutes

Multiply each by 7

7 hours = 7*60 minutes = 420 minutes

So 7 hours 30 minutes = 420 + 30 = 450 minutes

Bottle caps = rate * minutes

                   = 80 caps/minute * 450 minutes

                    = 36000 caps

The machine can put tops on 36,000 bottles between 8:00 a.m. and 3:30 p.m.

To calculate how many tops can be put on bottles at a factory between 8:00 a.m. and 3:30 p.m. by a machine that works at a rate of 80 bottles per minute, we need to determine the total number of minutes the machine operates between those times and then multiply that number by the rate of the machine.

First, let's find the difference in time from 8:00 a.m. to 3:30 p.m.:

Therefore, the machine operates for a total of 7 hours and 30 minutes. Since 1 hour equals 60 minutes, we have:

7 hours * 60 minutes/hour = 420 minutes

420 minutes + 30 minutes = 450 minutes

Now we multiply the total minutes by the rate of the machine:

450 minutes * 80 bottles/minute = 36,000 bottles

So the machine can put tops on 36,000 bottles between 8:00 a.m. and 3:30 p.m.

Answer:

$377,358.49

Step-by-step explanation:

Let, the actual sales = $X

Given total sales amount including 6% of sales tax = $400,000

Therefore, (X+6% of X)= $400,000

⇒(X+X·6÷100)= $400,000

⇒(X+0.06X)= $400,000

⇒ 1.06X= $400,000

∴ X= $400,000÷ 1.06 = $ 377,358.49

Hence, the actual sales = $ 377,358.49

Answer:

$377,358.49

Step-by-step explanation:

We are given the total sales amount of $400,000 which has an included 6% of sales tax.

Assuming the actual sales to be x, we will use the following formula:

x + x * sales tax = total amount

x + x * 6% = $400,000

x + x * 0.06 = $400,000

x * 1.06 = $400,000

x = $400,000 / 1.06

x = $377,358.49

Therefore, a total sales amount of $400,000 that included a 6% sales tax yields actual sales of $377,358.49.

Answer:

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

To obtain this form use the method of completing the square on both the x and y terms

rearranging

x² + 6x + y² - 4y = 12

x² + 2(3)x + 9 + y² + 2(- 2)y + 4 = 12 + 9 + 4

(x + 3)² + (y - 2)² = 25 ← in standard form

with centre = (- 3, 2) and r = [tex]\sqrt{25}[/tex] = 5

Answer:

The radius = 7 units

Step-by-step explanation:

The diameter of a circle is twice the radius

d = 2r

If d =14 units

14 = 2r

Divide each side by 2

14/2 = 2r/2

7 =r

The radius = 7 units

Answer:

Answer: The measure of JK is 60 and the correct option is d.

Explanation:

It is given that the points F, G, and H are the midpoints of the sides of triangle JKL , FG = 37, KL = 48, and GH = 30.

The point F is midpoint of JK, point G is midpoint of KL and the point H is midpoint of LJ as shown in figure .

According to the midpoint theorem, the line connecting the midpoints of two sides is parallel to the third and its length is half of the third side.

By midpoint theorem,

Therefore the measure of JK is 60 and the correct option is d

The measure of FH = 24 units, measure of JL = 74, measure of KJ = 60

and, measure of FJ = 30.

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

As given in the question,

F, G, and H are the midpoints of the sides of ΔJKL.

F is the midpoint of KJ, G is the midpoint KL, H is the midpoint of JL

Measure of the required sides are as follow:

FH = (KL / 2)                         (by midpoint theorem)

    = (48/2)

    = 24

JL = 2 x FG             (by midpoint theorem)

  = 2 x 37

  = 74  

KJ = 2 x GH             (by midpoint theorem)

   = 2 x 30

   = 60

FJ = GH = 30            (by midpoint theorem)

Therefore, measure of FH = 24, measure of JL = 74, measure of KJ = 60 and measure of FJ = 30.

Answer:

actually it is x=0

Step-by-step explanation:

keeping in mind that the x-intercept is where the graph touches the x-axis, and when that happens, y = 0, thus

Answer: x-intercept = 1

Step-by-step explanation: To solve this problem, we need to remember that the y-intercept is the point where the line crosses the y-axis. So if our line has a y-intercept of 3, it crosses the y-axis up 3 units. So we start this problem by plotting the point (0,3) on y-axis and we can label that point A.

From there, our slope of -3 can be thought of as -3/1 so we go down 3 units and to the right 1 unit and we plot point B. Notice that point B happens to lie on the x-axis at (1,0) and it's important to understand that the x-intercept is the point where the line crosses the x-axis.

Since our line crosses the x-axis at the point (1,0), it as an x-intercept of 1. If you're given a y-intercept and a slope like you are in this problem, you won't always be able to determine the x-intercept but things work out nicely here because point B happens to lie on the x-axis.

Final answer:

Only the set of ordered pairs listed in option a. (1,2), (2,4), (3,5) represents a function because each element of the domain is mapped to a unique element of the range.

Explanation:

To determine which of the given terms is a function, we recall that a function is a relation where each element of the domain (the first member of an ordered pair) is mapped to a single, unique element of the range (the second member of the ordered pair).

Option a - (1,2), (2,4), (3,5) has no repeated domain elements, so it is a function.

Option b - (1,2), (2,3), (1,5) has the domain element '1' mapped to two different range elements (2 and 5), so it is not a function.

Option c - (1,2), (2,4), (2,6) has the domain element '2' mapped to two different range elements (4 and 6), so it is not a function.

Option d - (1,2), (3,5), (3,7) has the domain element '3' mapped to two different range elements (5 and 7), so it is not a function.

Therefore, the correct answer is: a. Function 1 only.

Answer:

t(1) = -3.5, Recursive equation is t(n) = t(n-1) + 4.5

Step-by-step explanation:

t(n)=4.5n-8

Let find the sequence

Plug in n=1,2,3,4.....

n=1      t(1)=4.5(1) -8= -3.5

n=2      t(2)=4.5(2) -8= 1

n=3      t(3)=4.5(3) -8= 5.5

n=4      t(4)=4.5(4) -8= 10

so sequence is -3.5, 1, 5.5, 10................

Now we find the common difference

1 - (-3.5) = 4.5

5.5-1 = 4.5

10 - 5.5 = 4.5

common difference d = 4.5

Formula for recursive function is

t(n) = t(n-1) + d

We got d= 4.5

t(n) = t(n-1) + 4.5 , also t(1) = -3.5

Final answer:

The student seems confused between a linear and a quadratic equation. The provided equation is linear (t(n) = 4.5n - 8), while the supporting information describes how to solve a quadratic equation using the quadratic formula with specified coefficients.

Explanation:

The question posed by the student pertains to a recursive equation, which is a formula that defines each term of a sequence using preceding terms. However, the recursive equation mentioned (t(n) = 4.5n - 8) seems to be a simple linear equation rather than a recursive one. The student may be asking for a recursive form, but has provided a linear formula instead.

The additional information provided references a quadratic equation where the coefficients a, b, and c are given as 4.90, ±14.3, and ±20.0, respectively. The general form of a quadratic equation is at² + bt + c = 0. The solutions to this quadratic equation can be found using the quadratic formula, which is x = (-b ± √(b² - 4ac)) / (2a). To find the solutions to the given quadratic equation, the values of a, b, and c would be substituted into the quadratic formula and the resulting expression solved.

For clarity, it seems there might be some confusion in the question as it mixes linear and quadratic equations. It is important to correctly identify the type of equation and its coefficients to proceed with finding a solution.
