Liam bought pizza and wings for $27.58. How much change should Liam receive if he gave the clerk three $10 bills?
Use coins and bills to help solve.
A. $1.52
B. $2.42
C. $2.52
D. $12.42
Answer:
B. $2.42
Step-by-step explanation:
If Liam gave the clerk three $10 bills, that means he gave the clerk $30. This is because 3 times 10 equals 30.
Find how much change he will receive by subtracting $27.58 from the $30 that Liam gave to the clerk:
30 - 27.58
= 2.42
So, Liam will receive $2.42 in change.
The correct answer is B. $2.42
Answer:
2.42
Step-by-step explanation:
3 ten dollar bills = 3*10 = 30 dollars
Subtract the cost of pizza and wings
30 - 27.58
Line up the decimals
30.00
- 27.58
----------------
2.42
In circle S with mZRST = 86 and RS = 4 units find area of sector RST. Round to
the nearest hundredth.
R
S
T
Answer:
[tex]Area = 12.00[/tex]
Step-by-step explanation:
Given
[tex]\theta = m\angle RST = 86^o[/tex]
[tex]r = RS = 4[/tex]
Required
Area of RST
The sector area is calculated using:
[tex]Area = \frac{\theta}{360} * \pi r^2[/tex]
So, we have:
[tex]Area = \frac{86}{360} * 3.14 *4^2[/tex]
[tex]Area = \frac{86* 3.14 *4^2}{360}[/tex]
[tex]Area = \frac{4320.64}{360}[/tex]
[tex]Area = 12.00[/tex] ------------ approximated

Answer:
x = 6.93
y = 13.86
Step-by-step explanation:
We can solve x by;
Tan(60) = 12/x
Tan(60) * x = 12
x = 12 / Tan(60)
x = 6.93
We can solve y by;
A² + B² = C²
12² + 6.93² = y²
144 + 48.02 = y²
192.02 = y²
[tex]\sqrt{192.02}[/tex] = y²
13.86 = y

Answer:
m∠1 = 81
m∠2 = 99
Step-by-step explanation:
The angles are supplemaentary and therefor sum to 180
3x + (x + 72) = 180
4x + 72 = 180
4x = 108
x = 27
m∠1 = 3x
m∠1 = 27(3)
m∠1 = 81
m∠2 = x + 72
m∠2 = 27 + 72
m∠2 = 99

Umm, where's the question?????
Suppose the ages at retirement for workers in the U.S. are normally distributed with an unknown population mean and standard deviation. If a random sample of 43 retirees is taken to estimate the mean retirement age, what t-score should be used to find a 80% confidence interval estimate for the population mean?
Answer: 1.302
Step-by-step explanation:
The sample used was 43 retirees, so n=43. To find the degrees of freedom:
df=n−1=43−1=42
The confidence level is given in the scenario: 80%. So,
α=1−CL=1−0.8=0.2
But we want to use the value for α2, which is 0.22=0.1. Using the table, we need to find the row for 42 degrees of freedom, and the column for t0.1. So, the t-score we would use to find the 80% confidence interval is 1.302.
We could also use a calculator and input 1−α2=0.9 and the degrees of freedom into invT, in which case we would enter invT(0.9,42).
The solution is: 1.302, is the t-score should be used to find a 80% confidence interval estimate for the population mean
What is the confidence interval?A confidence interval is a range of values, derived from a sample of data, that is likely to contain an unknown population parameter with a certain level of confidence.
here, we have,
The sample used was 43 retirees, so n=43.
To find the degrees of freedom:
df=n−1=43−1=42
The confidence level is given in the scenario: 80%. So,
α=1−CL=1−0.8=0.2
But we want to use the value for α2, which is 0.22=0.1. Using the table, we need to find the row for 42 degrees of freedom, and the column for t0.1. So, the t-score we would use to find the 80% confidence interval is 1.302.
We could also use a calculator and input 1−α2=0.9 and the degrees of freedom into invT, in which case we would enter invT(0.9,42).

2.02b + 4.30 = 2.00b + 6.30
Answer: b = 100
Step-by-step explanation:
simplifying
2.02b + 4.30 = 2.00b + 6.30
reorder the terms:
4.30 + 2.02b = 2.00b + 6.30
reorder the terms:
4.30 + 2.02b = 6.30 + 2.00b
solving
4.30 + 2.02b = 6.30 + 2.00b
solving for variable 'b'.
move all terms containing b to the left, all other terms to the right.
add '-2.00b' to each side of the equation.
4.30 + 2.02b + -2.00b = 6.30 + 2.00b + -2.00b
combine like terms: 2.02b + -2.00b = 0.02b
4.30 + 0.02b = 6.30 + 2.00b + -2.00b
combine like terms: 2.00b + -2.00b = 0.00
4.30 + 0.02b = 6.30 + 0.00
4.30 + 0.02b = 6.30
add '-4.30' to each side of the equation.
4.30 + -4.30 + 0.02b = 6.30 + -4.30
combine like terms: 4.30 + -4.30 = 0.00
0.00 + 0.02b = 6.30 + -4.30
0.02b = 6.30 + -4.30
combine like terms: 6.30 + -4.30 = 2
0.02b = 2
divide each side by '0.02'.
getting: b = 100

NO LINKS NO FILES! Jill says that the rules for multiplying and dividing integers are alike. Do you agree? Explain.
Answer:
Multiplying and dividing fractions are essentially the same process which you multiply the numbers straight across and no need for common denominators. Except in division of fractions, the second fraction is flipped so that the denominator is on the top and the numerator is on the bottom (reciprocal).
Answer:
I do not agree
Step-by-step explanation:
because in multiply negatives, the 2 negatives turn into a positive or multiplying positive and negative (and vice versa) becomes a negative still so the rules of multiplying and dividing are not alike integers. (For dividing it is the same!)

Randy's gross salary is $760 per week. his salary is taxed at 16% what is his net salary
Answer:
$638.4
Step-by-step explanation:
Randy's gross salary (salary without any deduction) = $760
taxed rate =16%
Amount tax paid =tax% of gross income
=16/100 * $760
=$16*760/100
=$12160/100
=$121.6
net salary = gross salary - tax paid
=$760 - $ 121.6
=$638.4
Randy's net salary is $638.40
Randy's gross salary = $760 per week.
Tax paid on his salary = 16%
Net salary is the difference between the salary earned and the amount paid as tax. This will be:
= Salary - Tax
= $760 - (16% × $760)
= $760 - (0.16 × $760)
= $760 - $121.60
= $638.40

Opposite pairs of sides are the same length, so the total length needed is ...
2(8 4/5 +14 17/25) = 2(8 20/25 +14 17/25) = 2(22 37/25) = 2(23 12/25)

A, B, and C are the coefficients. They are not the terms as you have written now.
A quadratic equation is in the form Ax^2 + Bx + C. Therefore, A = 1, B = 8, and C = -6.
The axis of symmetry is found using the equation -b/2a, as you've done. Therefore, the axis of symmetry is -8/2(1) = -4.

Answer: C(t) =0.10t+25
Step-by-step explanation:
you can plug in the information as a slope of a line. (55-40)/(300-150) = 0.10
then enter it into the point slope form with point (150,40)= y-40=0.10(x-150) when done you get y=0.10x+25 which is the answer C(t)=0.10t+25
