The age of a father is 2 less than 7 times the age of his son. In 3 years, the sum of their ages will be 52. If the son age is s years, which equation models this situation?

a. (s+3)+[(7s-2)+3}=52
b. 3s+3+3(7s-2)= 52
c. s+(7s-2)=52
d. (s-3)+(7s-2)-3=52

Answers

Answer 1
First,
the age of the son: s
the age of the father is 2 less than 7 times the age of his son: 7s - 2
In 3 years, the sum of their ages will be 52,
In 3 years, the age of the sun will increase 3, so s+3. Also, the age of his father also increase 3, (7s - 2) + 3

(s+3) + [(7s-2) + 3] = 52 is the equation.

The area of a square is greater than the area of the circle by 12 cm². find the length of the side of a square if the area of the circle is 36 cm².

Answers

Area of the square: 36 cm^2 + 12cm^2
                     48cm^2

area of a square: side x side
48cm^2=side1^2 (sides of squares are all equal, so the same length is being multiplied by itself)

√ 48 cm^2

one side: 
4√ 3 cm, or approximately 6.93cm

Final answer:

To find the length of a side of the square, calculate the square root of the sum of the areas of the circle (36 cm²) and the additional 12 cm². This results in a square side length of approximately 6.93 cm.

Explanation:

We are given that the area of the circle is 36 cm², and we know that the area of a square is greater than the area of the circle by 12 cm², which means the area of the square is 36 cm² + 12 cm² = 48 cm².

The area of a square is given by A = a², where a is the length of the side of the square. So, we need to find the value of a that satisfies the equation a² = 48 cm².

By taking the square root of both sides of the equation, we get a = √(48 cm²). Simplifying the square root of 48 gives us a ≈ 6.93 cm. Therefore, the length of a side of the square is approximately 6.93 cm.

What is the value of n? Enter your answer in the box.

Answers

Answer:

n=6

Step-by-step explanation:

Since, we know that  when two chords intersect each other inside a circle, the products of their segments are equal. Thus, using this property, we have

[tex](n+8)5=(n+4)7[/tex]

⇒[tex]5n+40=7n+28[/tex]

⇒[tex]40-28=7n-5n[/tex]

⇒[tex]12=2n[/tex]

⇒[tex]n=6[/tex]

Thus, the value of n is 6.

Answer:

[tex]n=6[/tex]

Step-by-step explanation:

We have been given an image of a circle. We are asked to find the value of n.

We can see that two chords of our given circle are intersecting inside it, so we will use intersecting chords theorem to solve for n.

Intersecting chords theorem states that when two chords of a circle intersect inside the circle, then product of the segments of both chords is equal.

Using intersecting chords theorem we can set an equation as:

[tex]5(n+8)=7(n+4)[/tex]

Using distributive property [tex]a(b+c)=a*b+a*c[/tex] we will get,

[tex]5*n+5*8=7*n+7*4[/tex]

[tex]5n+40=7n+28[/tex]

Subtracting 40 and 7n from both sides we will get,

[tex]5n-7n+40-40=7n-7n+28-40[/tex]

[tex]-2n=-12[/tex]

Dividing both sides by -2 we will get,

[tex]\frac{-2n}{-2}=\frac{-12}{-2}[/tex]

[tex]n=6[/tex]

Therefore, the value of n is 6.

The average speed of a car is three times as fast as the average speed of a cyclist. to travel 225 km, the cyclist requires 5 h more than the car. determine the average speeds of the cyclist and the car.

Answers

Final answer:

To determine the speeds, we set up relative speed equations and solve for 'x'. The cyclist's average speed is 15 km/h and the car's average speed is 45 km/h.

Explanation:

Let's denote the cyclist's speed as 'x' km/h and the car's speed as '3x' km/h (since it's three times the cyclist's speed).

Given that speed is distance over time, we can set up the following equations:

For the cyclist: 225km / x = time, and for the car: 225km / 3x = time - 5.

By equating these two expressions, we get: 225/x = 225/3x + 5.

Solving this equation for 'x', we get x = 15. Thus, the average speed of the cyclist is 15 km/h and the car (3x) is 45 km/h.

Step-by-step explanation:

It is given that a quadrilateral ABCD is inscribed in a circle, and from the properties of circle, we know that the sum of the opposite angles of the quadrilateral inscribed in the circle is equal to 180°.

Therefore, ∠A+∠C=180°

The probability that Natalie got all four quiz questions correct after guessing would be 6. 25 %.

If Natalie guessed on the last four true or false questions, there are two possible outcomes for each question (correct or incorrect), and she has a 50% chance of guessing correctly for each question since there are only two options.

To find the probability that she got all four quiz questions correct, you can multiply the probabilities for each question:

Probability of guessing a question correctly = 0.5 (since there are 2 options, and she has a 50% chance of guessing correctly)

Probability of getting all four questions correct = (0.5) * (0.5) * (0.5) * (0.5)

a school district requires all graduating seniors to take a mathematics test. This year, the rest scores were approximately normally distributed for the 1208 graduating seniors. This mean score on the test was a 74 and the standard deviation was 11. what percent of the graduating seniors had a test above 85? Express your answers to the nearest percent.

Answers

A score of 85 would be 1 standard deviation from the mean, 74.  Using the 68-95-99.7 rule, we know that 68% of normally distributed data falls within 1 standard deviation of the mean.  This means that 100%-68% = 32% of the data is either higher or lower.  32/2 = 16% of the data will be higher than 1 standard deviation from the mean and 16% of the data will be lower than 1 standard deviation from the mean.  This means that 16% of the graduating seniors should have a score above 85%.

Based on the mean score of the test, the percentage of students who scored above 85% in the test was 16%.

Which students scored above 85 in the test?

Based on the fact that this distribution is normally distributed, the percentage of students that scored higher or lower than 85% within 1 standard deviation is:

= 100% - 68%

= 32%

The number of students who scored above 85% would therefore be:

= 32% / 2

= 16%

The measurement of one angle of a right triangle is 34°.

What is the measurement of the third angle?

Enter your answer in the box.

Answers

The third angle is 56 degrees because it is a right triangle, so the three angles will add up to 180 degrees.  Since it is a right triangle, you know one angle is 90 degrees.  All you have to do is add 90 and 34, and then subtract that from 180 to get your third angle.

Final answer:

The third angle of the right triangle is calculated by subtracting the sum of the known right angle (90°) and the given angle (34°) from the total sum of angles in a triangle (180°), which equals 56°.

Explanation:

To find the measurement of the third angle in a right triangle where one of the angles is 34°, we use the fact that the sum of the angles in any triangle is 180°. Since one angle is 34° and another is by definition 90° in a right triangle, we can subtract these two angles from 180° to find the third angle:

Sum of angles in a triangle = 180°

Two known angles: 90° (right angle) + 34° = 124°

Third angle = 180° - 124° = 56°

Therefore, the measurement of the third angle is 56°.

Answers

You did not give any choices but this can easily be solved using the FOIL method. 

FOIL stands for First, Outside, Inside, Last. 

In your equation you have (6x-2)(6x+2)
You will multiply the terms that correspond to each letter 

First: Means first terms of each set. In this case 6x and 6x
6x x 6x = [tex] 36x^{2} [/tex] Now you have your first term in the sequence.

Outside: Means terms found in the outside areas of the whole equation, in this case it is 6x and 2
6x x 2 = 12x Now this is the second term

Inside: Means terms found in the inside areas of the whole equation, in this case it is -2 and 6x
-2 x 6x = -12x Now this is your third term

Last: Means the last terms of each set. In this case it is -2 and 2
-2 x 2 = -4  This is your last term

Now you have what you need for your new equation:

[tex] 36x^{2} + 12x -12x - 4 [/tex]

Because your second and third terms are like terms, you can combine them by doing the operation indicated. 12x-12x = 0 so now you can cancel it out from your equation and your left with:

[tex]36 x^{2} - 4 [/tex] This is your product
