Ron and kathy are ticket sellers at their class play. ron handles student tickets that sell for $2.00 each, and kathy handles adult tickets that sell for $4.50 each. if their total income for 364 tickets was $1,175.50, how many tickets did ron sell?

Answers

Answer 1

185 tickets

You can get this by setting up a system of equations and solving by substitution.

x + y = 364 (number of tickets)
2x + 4.5y = 1175.50 (Cost)

A teacher asked her students to divide a large number by 50.
• Aslan divided the number by 50.
• Lucy divided the number by 5 and then divided the answer she got by 10.
• Jack divided the number by 10 and then divided the answer he got by 40.
Who among these got the correct answer assuming they did NOT make mistakes in division?

Answers

Answer:

Step-by-step explanation:

Final answer:

Aslan and Lucy got the correct answer of x/50, while Jack made a mistake in his calculation.

Explanation:

To find out who got the correct answer, we need to evaluate the division calculations of each student. Let's assume the large number is 'x'.

Aslan divided the number by 50, so his answer is x/50.

Lucy divided the number by 5 and then divided the answer by 10, so her answer is (x/5)/10 = x/50.

Jack divided the number by 10 and then divided the answer by 40, so his answer is (x/10)/40 = x/400.

Therefore, both Aslan and Lucy got the correct answer of x/50, while Jack made a mistake in his calculation.

Need help to write equations for 5, 6 & 7

Answers

6)
A quadratic function has the form
y = ax^2 + bx + c

Use point (3, 5) in the equation above:

5 = a(3^2) + 3b + c
5 = 9a + 3b + c
9a + 3b + c = 5     Equation 1

Use point (4, 3) in the equation above:

3 = a(4^2) + 4b + c
16a + 4b + c = 3    Equation 2

Use point (5, 3) in the equation above.

5 = a(5^2) + 5b + c
25a + 5b + c = 5       Equation 3.

Now solve the system of equations of equations 1, 2, and 3 to find the coefficients, a, b, and c.

9a + 3b + c = 5
16a + 4b + c = 3
25a + 5b + c = 5

Subtract the first equation from the second equation.
Subtract the second equation from the third equation.
You get
7a + b = -2
9a + b = 2

Subtract the first equation above from the second equation to get.
2a = 4
a = 2

Substitute:
7a + b = -2
7(2) + b = -2
b = -16

9a + 3b + c = 5
9(2) + 3(-16) + c = 5
18 - 48 + c = 5
c - 30 = 5
c = 35

The equation in standard form is

y = 2x^2 - 16x + 35

We can find it in vertex form:

y = 2(x^2 - 8x) + 35

y = 2(x^2 - 8x + 16) + 35 - 32

y = 2(x - 4)^2 + 3

A boy flies a kite with a 100-foot-long string. The angle of elevation of the string is 48°. Find the vertical distance between the kite and the point at which the boy is holding the string.

Answers

The vertical distance will be given by:
sinθ=opposite/hypotenuse
where:
θ=48°
opposite=h
hypotenuse=100 ft
thus
sin 48=h/100
hence
h=100 sin48
h=74.315 ft

Answer: 74.315 ft

Using the sine function of trigonometry, the vertical distance between the kite and the point where the boy is holding the string is calculated to be approximately 74.31 feet when the string's angle of elevation is 48 degrees.

To find the vertical distance between the kite and the point at which the boy is holding the string, we can use trigonometric functions, specifically the sine function which is defined as the ratio of the opposite side to the hypotenuse in a right triangle. Since we know the length of the string, which acts as the hypotenuse of the triangle, and the angle of elevation, we can set up our equation as follows:s

sin(48°) = opposite/hypotenuse

sin(48°) = vertical distance/100 feet

W then multiply both sides by the hypotenuse (100 feet) to solve for the vertical distance:

vertical distance = 100 feet \sin(48°)

To get the numerical value, we use a calculator to find:

vertical distance ≈ 100 feet * 0.7431

vertical distance ≈ 74.31 feet

Therefore, the vertical distance between the kite and the point where the boy is holding the string is approximately 74.31 feet.

What is the sum or difference 6x^7+8x^7

Answers

Answer: 14x^7

You add the coefficients (numbers to the left of the variable terms) to get 6+8 = 14 which is the coefficient of the final answer. The x^7 stays the same. It's like saying "we have 6 apples added to 8 apples, so there are 14 apples overall". Replace "apples" with "x^7" and it's the same idea.

Final answer:

The sum of the expressions 6x^7 and 8x^7 is 14x^7. This follows the simple rule of addition with similar terms, where the coefficients are added together while the variable remains the same.

Explanation:

The sum of 6x7 and 8x7 follows the usual rules of addition, it treats similar terms in a similar way to ordinary numbers. To combine these expressions, you simply add or subtract the coefficients (the number parts), while keeping the variables (the letter parts) the same. In this case, the variable is x7. Thus, adding the coefficients 6 and 8 gives you 14, and you keep the x7 the same. The sum is therefore 14x7.

In a certain population, 95% of the people have rh-positive blood. suppose that two people from this population get married. what is the probability that they are both rh-negative, thus making it inevitable that their children will be rh-negative? web assign answer

Answers

P(rh-positive) = 95% = 0.95

Therefore,
P(rh-negative) = 1-P(rh-positive) = 1-0.95 = 0.05

Then,
P(rh-negative) for both parents = 0.05*0.05 = 0.0025

Final answer:

The probability that both partners in a marriage are Rh-negative in a predominantly Rh-positive population is 0.25% or 1 in 400, critical for understanding the risk of hemolytic disease of the newborn in subsequent pregnancies.

Explanation:

The probability that both people in a marriage are Rh-negative in a population where 95% of the people are Rh-positive is calculated using the complement. Assuming that 5% of the population is Rh-negative, we would calculate the probability that both parents are Rh-negative by multiplying the individual probabilities:

P(both Rh-negative) = P(one Rh-negative) × P(other Rh-negative) = 0.05 × 0.05 = 0.0025

Therefore, the probability that both people are Rh-negative, and thus all of their children would also be Rh-negative, is 0.25% or 1 in 400.

Rh factor and blood type compatibility are crucial in reproduction and transfusion medicine. Understanding these concepts can help prevent complications such as hemolytic disease of the newborn, which occurs during second or subsequent pregnancies due to sensitization of the Rh-negative mother's immune system to Rh-positive fetal cells from a previous pregnancy.

92.4 is 150% of what number?

Answers

1. We assume, that the number 92.4 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 92.4 is 100%, so we can write it down as 92.4=100%.
4. We know, that x is 150% of the output value, so we can write it down as x=150%.
5. Now we have two simple equations:
1) 92.4=100%
2) x=150%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
92.4/x=100%/150%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 150% of 92.4

92.4/x=100/150
(92.4/x)*x=(100/150)*x - we multiply both sides of the equation by x
92.4=0.666666666667*x - we divide both sides of the equation by (0.666666666667) to get x
92.4/0.666666666667=x
138.6=x
x=138.6

now we have:
150% of 92.4=138.6

Answer:

Number is 61.6

Step-by-step explanation:

Given : 92.4 is 150%.

To find : what number.

Solution : We have given 92.4 is 150%.

Let the number = x

According to question :

150% of x = 92.4

[tex]\frac{150}{100} *x[/tex] = 92.4

On multiplying both sides by 100

150 x = 92.4 * 100.

150 x = 9240

On dividing both sides by 150 .

x = [tex]\frac{9240}{150}[/tex].

x = 61. 6

Therefore, Number is 61.6

Remark
There are a number of ways you could do this. The most straight forward might be to simply multiply the second equation to get the answer.

Step One
Multiply the second equation by 2
2(2x^2 + 1/y^2 = 12) Remove the brackets.
4/x^2 + 2/y^2 = 12 * 2
4/x^2 + 2/y^2 = 24

Step Two
Add the new equation and the first original equation
1/x^2 - 2/y^2 = 1
4/x^2 + 2/y^2 = 24

5 / x^2 = 1 + 24
5/x ^2 = 25 Divide both sides by 5
1/x^2 = 5 Reciprocate the x^2 and the 5 (That means turn them upside down.

x^2 = 1/5

Continued
5 - 2 / y^2 = 1 Subtract 5 from both sides.

-2 / y^2 = - 4 Divide both sides by - 2
1 / y^2 = -4/-2
1 / y^2 = 2 Now reciprocate both sides.
y^2 = 1/2 Take the square root.
y = +/- 1/sqrt(2) And rationalize the denominator
