Summer spent $55.60 on clothes before sales tax. If sales tax is 7.5%, what did Summer spend with tax included?  *Add Explanation If U Can*

Answers

Answer 1
$59.77. Turn the percent into a decimal by moving the decimal to the left two places (7.5 to 0.075). Then multiply the new decimal by the cost (55.60×0.075=4.17). 4.17 would be the total sales tax, so then add it to the price (55.77+4.17=59.77). Hope that helped.

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.

A carpenter earns $18 an hour for a regular work week (40) hours. He earns time and a half for overtime. The weekly wage function is W(h)={                  18h                                         040} where h is the number of hours worked for the week. Find the wage if the carpenter worked 42.5 hours in the week

Answers

18×40=720 regular time
18×1.5=27 overtime per hour
27×2.5= 67.5 overtime

$720+$67.50=$787.50

Final answer:

To find the carpenter's weekly wage after working 42.5 hours, we calculate the regular pay for 40 hours at $18 per hour, which is $720, and then add the earnings from 2.5 hours of overtime at time and a half ($27 per hour), which is $67.5. The total weekly wage is $787.5.

Explanation:

To calculate the weekly wage of the carpenter who worked 42.5 hours, with $18 per hour for the first 40 hours and time and a half for overtime, we will use the wage function provided: W(h) = 18h for hours up to 40, and for hours above 40, it's (18 × 1.5) × (h - 40). Let's apply this to the 42.5 hours worked.

The carpenter's earnings for the regular 40 hours are $720 (which is 40 hours × $18). For the 2.5 hours of overtime, he earns time and a half, which is $27 per hour (18 × 1.5). The overtime earnings are $67.5 (2.5 hours × $27). So, the total wage is:

$720 + $67.5 = $787.5

Therefore, the carpenter's weekly wage for working 42.5 hours at the given rate is $787.5.

Need help to write equations for 5, 6 & 7

Answers

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

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.

 The first thing we must do is to group terms with the same degree:
 g ^ 2 (1/2 + 3) - 4 / 5g + (7/2 + 1/4)
 Then, rewriting we have:

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.

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
