Answer:

x = 40

Step-by-step explanation:

The figure shows two similar triangles. Thus, the side lengths of similar triangles are proportional to each other. Therefore:

[tex] \frac{24}{24 - 15} = \frac{x}{x - 25} [/tex]

[tex] \frac{24}{9} = \frac{x}{x - 25} [/tex]

Cross multiply

[tex] 24(x - 25) = 9(x) [/tex]

[tex] 24x - 600 = 9x [/tex]

Subtract 24x from each side

[tex] - 600 = 9x - 24x [/tex]

[tex] - 600 = -15x [/tex]

Divide both sides by -15

[tex] 40 = x [/tex]

x = 40

Does the MVT apply? Explain why or why not.
y=x^2/4x + 4 ;

Answers

Hello!

[tex]\large\boxed{\text{Yes, it does.}}[/tex]

In order to use the MVT, the function must be continuous over the given interval.

[tex]y = \frac{x^{2} }{4x}+4[/tex]

Simplifies to:

[tex]y = \frac{x}{4} + 4[/tex]

This is a linear equation that is continuous on the interval (-∞, ∞), which  means that it would also be continuous on the interval [-6, -2]. The MVT would apply to this function.

If sales tax is 7%, how much tax will Miguel pay for a TV that costs $150?

Answers

Answer:

$10.50

Step-by-step explanation:

To find how much tax is added on to the $150 we have to multiply .07 by 150.

(150)(.07) = 10.5

Therefore, Miguel will have to pay $10.50 in tax.

Four different stores sell packages of organic brown rice. The prices at each store are shown in the table.

Which store has the lowest price per pound?

A. Eat Right Grocery
B. Good Food Market
C. Health First Store
D. Food for Life Market​

Answers

The answer is A since I did the math trust me A is correct since A is 1.16 and B is 1.24 and C is 1.41 and D is 1.45
Answer: A) Eat Right Grocery

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

Work Shown:

For each store, divide the cost over the size to get the unit price.

Eat Right Grocery: 2.32/2 = 1.16Good Food Market: 3.70/3 = 1.23Health First Store: 5.65/4 = 1.41Food for Life Market: 7.28/5 = 1.46

Round each result to the nearest penny. We see that Eat Right Grocery has the lowest unit price, or price per pound.

----------------------

Further explanation:

Let's look at the first row of the table. This says that 2 pounds of rice cost 2.32 dollars. We can form an equation of sorts

2 pounds = 2.32 dollars

Divide both sides by 2 to turn that "2 pounds" into "1 pound". This is because "price per pound" really means "price per 1 pound" or "price for each 1 pound"

So we get

2 pounds = 2.32 dollars

2/2 pounds = 2.32/2 dollars

1 pound = 1.16 dollars

Telling us the unit cost for Eat Right Grocery is $1.16 per pound. The other stores unit prices are calculated the same way.

The weekly demand for an item in a retail store follows a uniform distribution over the range of 50 to 100. What would be the weekly demand if its corresponding computer-generated value is 0.4?a. 60b. 70c. 75d. 80

Answers

Answer: 70

Step-by-step explanation:

Given that :

Uniform range of distribution = 50 to 100

50 ≤ x ≤ 100

Difference between both values = 100 - 50 = 50

Range / difference = computer generated value

(Weekly demand - lower limit) / difference = computer generated value

(Weekly demand - 50) / 50 = 0.4

Weekly demand - 50 = 20

Weekly demand = 20 + 50

Weekly demand = 70

The weekly demand if the corresponding computer-generated value is 0.4 is given by: Option B: 70

What is the property of a uniformly distributed random variable?

A uniformly distributed random variable's probability is distributed uniformly in the interval in which it is defined. Thus, if X ranges from a to b, and pertains uniform distribution, then its probability density function is given by;

[tex]f(x) = \dfrac{1}{b-a}; a < x < b\\\\f(x) = 0; x < a , b < x[/tex]

For the given case,  the weekly demand(let it be tracked by random variable X) is in range 50 to 100.

The computer generated value shows:

[tex]\text{Computer generated value} = \dfrac{\text{Weekly demand} - \text{Lower limit}}{\text{difference between upper and lower limit}}[/tex]

(computer generated value is showing in range 0 to 1, the part occupied by the weekly value from starting, here as it is 0.4, so it means out of 50 values, it is 0.4 = 40% of (100 -50) = 20 (from start which is 50, thus, 50 + 20  = 70) )


As we've got:

Computer generated value = 0.4Lower limit = 50,Difference between upper and lower limit = 100 - 50 = 50,

Thus, the weekly demand is obtained as:


[tex]0.4 = \dfrac{\text{Weekly demand} - 50}{50}\\\\\text{Weekly demand} = 0.4 \times 50 + 50 = 70[/tex]

Thus, the weekly demand if the corresponding computer-generated value is 0.4 is given by: Option B: 70

A phone company has two long distance
calling plans. The first plan is $25 per month
for unlimited long distance calling. The second
plan is $10 per month plus $0.05 per minute
of long distance calling. After how many
minutes oflong distance calls will it be cheaper
for a customer to purchase the first plan?

Answers

It is cheaper for a customer to purchase the first plan if they make more than 300 minutes of long-distance calls. The answer is (C) 300.

Let's denote the number of minutes of long-distance calls as x. Then, the total cost of the second plan would be:

Cost of Plan 2 = $10 + $0.05x

The total cost of the first plan is always $25, regardless of the number of minutes of long-distance calls.

So we need to find the value of x at which the cost of Plan 2 exceeds the cost of Plan 1, i.e. when:

$10 + $0.05x = $25

Subtracting $10 from both sides, we get:

$0.05x = $15

Dividing both sides by $0.05, we get:

x = 300

So for values of x greater than 300, the cost of Plan 2 will exceed the cost of Plan 1.

to subtract fractions, we need an lcd( lowest common denominator)

8. the lcd is 42 because it’s the smallest number that 6 and 7 are both factors of. the lcd is the bottom of the fraction

to make the denominator of (4/7) 42, we will multiply the top and bottom by 6 and we get (24/42)

to make the denominator of (3/6) 42, we will multiply the top and bottom by 7 and we get (21/42)

these two numbers now have the same denominator so we subtract them

24/42 - 21/42 = 3/42 which simplifies to 1/14

9. since these fractions already have a common denominator, we will make them mixed fractions

-5(2/7) as a mixed fraction. first multiply 5*7 which is 35. now add 2 which is 37. our mixed fraction is -37/7

-1(5/7) as a mixed fraction. multiple 1*7 which is 7. now add 5 which is 12. our mixed fraction is -12/7

now subtract (-37/7) - (12/7) and we get -49/7 which simplifies to -7

All real numbers are solutions.

Two parallel lines are cut by a transversal. What is the measure of angle6 ?

Answers

Answer:

A

Step-by-step explanation:

Angle 3 and angle 6 are congruent because they are alternate interior angles. Angle 3 plus angle 1 is 180 degrees. So you just subtract 123 from 180 (180-123) and you get 57 degrees.

The measure of angle 6 is 57°

The correct answer is an option (A)

What are parallel lines?

"The lines in the same plane that are at equal distance from each other and never meet."

What is transversal?

"A line that passes through two lines in the same plane at two distinct points in the geometry. "

What are opposite angles?

"The angles directly opposite to each other when two lines intersect in a plane."

For given question,

Line n and line p are parallel lines and line t is the transversal.

Here, angle 1 and angle 4 are opposite angles.

⇒ ∠1 = ∠4

We have been given that ∠1 = 123°

⇒ ∠4 = 123°

Also, angle 4 and angle 6 are interior angles on the same side of the transversal.

We know that each pair of interior angles on the same side of the transversal is supplementary.

⇒ ∠4 + ∠6 = 180°

⇒ 123° + ∠6 = 180°

⇒ ∠6 = 180° - 123°

⇒ ∠6 = 57°

Therefore, the measure of angle 6 is 57°

The correct answer is an option (A)
