Answer:

$529.20

Step-by-step explanation:

If there are 30 days in a month and there are 12 months in a year,

30*12 = 360  

then there are 360 days in a year

Assuming we run at 7 hours per day

 7 hrs/ day * 360 days = 2520 hours

We will run 2520 hours in a year

At $.21 per hour,

.21* 2520 = 529.20

It will cost $529.20  to run the air conditioner for the year

None of the choices

Given:

240 red and blue cars

3:5 ratio of red cars to blue cars

3 + 5 = 8

red cars: 3/8 * 240 = 90

blue cars: 5/8 * 240 = 150

ratio of red cars to blue cars: 90:150

simplify:

 90 ÷ 30 = 3

150 ÷ 30 = 5 

Thus: 90:150 = 3:5

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:

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

Step-by-step explanation:

Looking at the graph When X is at 2 meals, the total cost is at Y = 3

Dividing the total coat of the mean by the number of means: 3 / 2 = 1.50

This means Fiona pays $1.50 per meal, which is less than the $1.75 Frank pays.

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

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:

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.

Final answer:

The commercial's claim that '80% of dentists recommend this toothpaste' might be misleading because it lacks context and does not specify the criteria or sample size used in the recommendation survey.

Explanation:

The commercial that says "80% of dentists recommend this toothpaste" might be misleading because the 80% figure does not provide the full context of the recommendation. It does not specify whether the recommendation is based on a survey of all dentists or a specific group of dentists. For example, if the survey only included a small sample of dentists who were given incentives to recommend the toothpaste, the result may not accurately represent the entire dentist population. Additionally, the commercial does not provide information about the criteria used for the recommendation. It is possible that the toothpaste is recommended for a specific condition or age group, but not necessarily for everyone. Therefore, it is important to critically evaluate such claims and look for more detailed information before making a decision based solely on the statistic provided in the commercial.

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:

7 units

Step-by-step explanation:

Radius is the same as saying diameter divided by 2. 14 divided by 2 = 7, so the radius is 7 units.

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.

B) 4[3(5+2)] not equal 95-4×3

Step-by-step explanation:

4[3(5+2)]=95-4×3

84=95-4x3

84=83

So since they are not equal B. is the correct answer!

Answer:

Option B.

Step-by-step explanation:

The given expression is

4[3(5 + 2)] = 95 - 4×3

We will solve the left side of the expression first

4[ 3(5 + 2)] = 4[ 3(7) ]

= 4 × 21

= 84

Now we take the right side of the expression

95 - 4×3

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: 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.
