Answer:
Total cost= $41.83
Step-by-step explanation:
Giving the following information:
Purchase price= $39
Tax rate= 7.25% = 0.0725
To calculate the total cost of the pair of shoes, we need to use the following formula:
Total cost= purchase price * (1 + tax rate)
Total cost= 39 * 1.0725
Total cost= $41.83

Answer:
B (5t + 15 ≤ 140) is correct
Step-by-step explanation:
Because since each table (t) seats 5 people, you'd represent that as 5t (5 seats per table).
Since there is one extra table that seats 15 people, you'd represent that as 15.
Lastly, those two last steps added together should have to be less than or equal to (≤) 140 (the amount of people allowed in the building).

Nancy's Cupcakes recorded how many cupcakes it recently sold of each flavor.
chocolate cupcakes 2
pistachio cupcakes 1
banana cupcakes 5
pumpkin cupcakes 6
Considering this data, how many of the next 21 cupcakes sold would you expect to be pumpkin cupcakes?
Answer:
pumpkin because it got the most sold
Answer:
9
Step-by-step explanation:
Knowing that
pumpkin = 6
Total =
chocolate cupcakes 2 + pistachio cupcakes 1 + banana cupcakes 5 +pumpkin cupcakes 6
Thus, 2 + 1 + 5 + 6 = 14
Cross multiply
[tex]\frac{6}{14}=\frac{x}{21}[/tex]
6 * 21 = 126
126/14 = 9
Hence, next 21 cupcakes sold that will be pumpkin cupcakes will 9 pumpkin cupcake

Calculate the slope of the lines using the rise/run formula.
Answer:
1. 3/4 2. -1/3
Step-by-step explanation:
#1:
Given rise/run, the rise is 3, and the run, is 4, so... 3/4
#2:
Given rise/run, the rise is 2, and the run is 6, so... you get 2/6 = 1/3. However, don't forget that the slope is negative, so it'll be -1/3.
Answer:
3. 3/4
4. -1/3
Step-by-step explanation:
Since the rise and run formula is slope = (y1-y2)/(x1-x2),
3. (2 - (-1) ) / (2- (-2) ) = 3/4
4. (-1- (-3) ) / (-2 - (-4) ) = -2/6 = -1/3

Answer:
28pi, 10pi
Step-by-step explanation:
So, lets go over a few things.
What is circumference?
Circumference is the permiteter of a circle.
The formula for it is 2*r*pi.
Now, lets go over what radius and diamater is.
Diamater is the distance between the two opposite sides of the circle.
The radius is half of the diamater, and is the distance between one side of the circle and the middle.
Problem #1:
The distance from the middle to the side of the circle is 14.
This will be the radius, not the diamater.
Lets plug this into the formula:
2*14*pi
=
28*pi
=
28pi
This is your answer.
Problem #2
The distance from the two opposite sides of the circle is 10.
So the radius will be half of this, being 5.
Now lets plug this in:
2*5*pi
=
10*pi
=
10pi
This is your answer.

Find the gradient of the line segment between the points (-2,3) and (-5,6)
Answer:
m = -1
Step-by-step explanation:
As we move from (-5, 6) to (-2, 3), x (the 'run') increases by 3 and y (the 'rise) decreases by 3. Hence the gradient, or slope, of this line segment is
m = rise / run = -3/3, or m = -1

A factory fills bottles with a beverage, and each bottle is supposed to contain 500\text{ mL}500 mL500, start text, space, m, L, end text. Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml. She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml. Norah wants to use these sample data to conduct a ttt test on the mean. Assume that all conditions for inference have been met.
Required:
Calculate the test statistic for Norah's test.
Answer:
The test statistic for Norah's test is [tex]t = -2[/tex]
Step-by-step explanation:
Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml.
This means that at the null hypothesis we test if the sample mean is 500 ml, that is:
[tex]H_0: \mu = 500[/tex]
At the alternate hypothesis, we test if it is differente than 500 ml, that is:
[tex]H_a: \mu \neq 500[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
500 is tested at the null hypothesis:
This means that [tex]\mu = 500[/tex]
She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml.
This means that [tex]n = 16, X = 497, s = 6[/tex]
Calculate the test statistic for Norah's test.
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{497 - 500}{\frac{6}{\sqrt{16}}}[/tex]
[tex]t = -2[/tex]
The test statistic for Norah's test is [tex]t = -2[/tex]

What is the constant of proportionality for the table below?
Answer:
Equation:y = 1/2x . or x = 2y
Constant = 2
Step-by-step explanation:
Input y = output x
the first input/output says that when inputed 2, the number 1 is outputted.
Similarly, when 5 is inputted, 2.5 is the output.
1/2 = 2.5/5
That means that y = 1/2 x
or x = 2y

Answer:
x = -4, -2
Step-by-step explanation:
Given equation is,
x² + 6x + 8 = 0
Let the equation to be graphed is,
y = x² + 6x + 8
y = x² + 2(3x) + 9 - 1
y = x² + 2(3x) + 3² - 1
y = (x + 3)² - 1
Table for the Input-output values
x -6 -4 -3 -2 -1 0
y 8 0 -1 0 3 8
Now we can plot these points on the graph as attached.
Since, this graph is intersecting x-axis at x = -4, -2
Therefore, solutions of the given equation will be x = -4, -2

Suppose a city with population 900,000 has been growing at a rate of 7% per year. If this rate continues, find the population of this city in 19 years
Answer:
Future population in 19 years = 3,254,580 people (Approx.)
Step-by-step explanation:
Given:
Current population of city = 900,000
Growth rate of population = 7%
Number of year = 19
Find:
Future population in 19 years
Computation:
A = P[1+r]ⁿ
Future population = Current population[1+g]ⁿ
Future population in 19 years = 900,000[1+7%]¹⁹
Future population in 19 years = 900,000[1+0.07]¹⁹
Future population in 19 years = 900,000[1.07]¹⁹
Future population in 19 years = 900,000[3.6162]
Future population in 19 years = 3,254,580
Future population in 19 years = 3,254,580 people (Approx.)
Jamal treated his family to a fancy brunch. Their brunch cost $250, and the local sales tax
was 4%. If Jamal left an 18% tip on the $250, how much in total did he pay?
Answer:
306.80
Step-by-step explanation:
250 + 4% = 260
260 + 18% = 306.80
Total amount paid by Jamal is $305
Step-by-step explanation:
Given that;
Cost of meal = $250
Local sale tax rate = 4%
Percentage of tip left by Jamal = 18%
Find:
Total amount paid by Jamal
Computation:
Total tax paid by Jamal = 250 × 4%
Total tax paid by Jamal = $10
Total amount of tip left by Jamal = 250 × 18%
Total amount of tip left by Jamal = $45
Total amount paid by Jamal = Cost of meal + Total tax paid by Jamal + Total amount of tip left by Jamal
Total amount paid by Jamal = 10 + 45 + 250
Total amount paid by Jamal = $305
