Answer:
$356.48
Step-by-step explanation:
We have been given that a jewelry salesperson earns [tex]6\frac{2}{5}[/tex]% commission on all sales. Today she sold $5,570 in jewelry.
To find the total commission earned by salesperson is same as finding the [tex]6\frac{2}{5}[/tex]% of 5,570.
Let us convert [tex]6\frac{2}{5}[/tex] in decimal form.
[tex]6\frac{2}{5}=6.4[/tex]
[tex]\text{Total commission earned by salesperson}=\frac{6.4}{100}\times 5,570[/tex]
[tex]\text{Total commission earned by salesperson}=0.064\times 5,570[/tex]
[tex]\text{Total commission earned by salesperson}=356.48[/tex]
Therefore, the total commission earned by salesperson is $356.48.
Luke's turkey chili recipe calls for 1.5 pounds of ground turkey for every 6 servings. How many servings can he make if he has 5 pounds of ground turkey? Show your work.
Final answer:
Luke can make 20 servings with 5 pounds of ground turkey.
Explanation:
To determine the number of servings Luke can make with 5 pounds of ground turkey, we need to set up a proportion. The recipe calls for 1.5 pounds of ground turkey for every 6 servings. So, we can set up the proportion: 1.5 pounds / 6 servings = 5 pounds / x servings, where x represents the unknown number of servings. To solve for x, we cross multiply: 1.5 pounds * x servings = 5 pounds * 6 servings. Simplifying the equation, we get: 1.5x = 30. Dividing both sides by 1.5, we find that x = 20. Therefore, Luke can make 20 servings with 5 pounds of ground turkey.

Answer:
Hello.
The answer is $6 each item.
Step-by-step explanation:
If all of the items are the same price, then we have a total of 7 items ( 3 keyboards + 4 mic = 7 items).
So at the end is: 7 items ÷ $42 = $6.
The cost of each item is $6.
What is Division?A division is a process of splitting a specific amount into equal parts.
Given that Mr. Vargas is buying used computer equipment. He buys 3 keyboards and 4 mice. He spends $42.

Determine the equation of the hyperbola.
Answer:
A) x²/9 -y²/4 = 1
Step-by-step explanation:
The distance from center to one vertex is half the difference of the distances from a point to either focus. That is, the distance from center to the vertex is 3 on the x-axis, so the x-term is (x/3)² = x²/9.
In the picture, ...
... c² = a² + b²
The problem statement tells us c = √13, so we know c² = 13. Then ...
... b² = c² - a² = 13 -9 = 4
and the y-term is y²/4.
Thus, the equation is ...
... x²/9 - y²/4 = 1

A hotel has 150 rooms. The charges for a double room are $270 per night and $150 per night for a single room. On a night when the hotel was completely occupied. Revenues were $33,300. Which pair of equation can be used to determine the number of double room, d and the number of single room,s,in the hotel?
Step-by-step explanation:
Let s be charges for a single room and d be charges for a double room per night.
We are told that a hotel has 150 rooms. We can represent this information as:
[tex]s+d=150...(1)[/tex]
The charges for a double room are $270 per night and $150 per night for a single room. So the charges for s single rooms will be 150s and charges for d double rooms will be 270d.
On a night when the hotel was completely occupied. Revenues were $33,300.
We can represent this information as:
[tex]150s+270d=33,300...(2)[/tex]
Therefore, our desired pair of equations will be:
[tex]s+d=150...(1)[/tex]
[tex]150s+270d=33,300...(2)[/tex]
Answer: First equation: s+d=150; second equation: 150s+270d=33300
Step-by-step explanation: To solve the given problem we need to write two equations, the first one will express that the total number of rooms is the sum of the single rooms an the double rooms. The second equation will include the sum of the total earnings for the single and double rooms:
First equation:
s+d=150 (the single rooms and the double rooms equal 150 rooms)
second equation:
150s+270d=33300 (the sum of the single and double rooms each one of them multiplied by their prices, equals the total revenue)
To solve the equation we isolate s from the first equation:
s=150-d
and we replace it in the second one:
150(150-d)+270d=33300
solving for d:
22500-150d+270d=33300
120d=33300-22500
120d=10800
d=10800/120
d=90.
now we calculate s from the first equation:
s=150-d
s=150-90
s=60.
There are 60 single rooms and 90 double rooms.
Pls help me with this Trig question!
Answer:
s = 65/3 pi
Step-by-step explanation:
The length of the intercepted arc is given by the formula
s =r*theta when theta is given in radians
r = 13
theta = 5 pi/3
Substituting what we know
s = 13 * 5 pi/3
s = 65/3 pi
Since we want an exact answer, we have to leave it in terms of pi and as a fraction
If A varies inversely as the square of B, what is the effect on B if A is multiplied by 3? Please explain.
Answer:
If A is multiplied by 3, B will be reduced by a factor [tex]\frac{1}{\sqrt{3}}[/tex]
Step-by-step explanation:
Writing the inverse proportionality relationship and expressing the dependence of B on A leads to the following:
[tex]A = \frac{1}{B^2}\implies |B| = \frac{1}{\sqrt{A}}\\B'=\frac{1}{\sqrt{3A}}= \frac{1}{\sqrt{3}}\frac{1}{\sqrt{A}}=\frac{1}{\sqrt{3}}|B|[/tex]
In words, if A triples, B will decrease by a factor [tex]\frac{1}{\sqrt{3}}[/tex], or, in other words, the square of B will decrease to one third of its previous value.
Brandon buys a basket of flowers for $7 before tax. The sales tax is 4%. What is the total price Brandon pays for the basket of flowers?
Answer:
$7.28
Step-by-step explanation:
We have been given that Brandon buys a basket of flowers for $7 before tax. The sales tax is 4%.
The total price that Brandon paid for the basket of flowers will be equal to 7 plus 4% of 7.
We can represent this information in an equation as:
[tex]\text{The total price that Brandon paid for the basket of flowers}=7+(\frac{4}{100}\times 7)[/tex]
[tex]\text{The total price that Brandon paid for the basket of flowers}=7+(0.04\times 7)[/tex]
[tex]\text{The total price that Brandon paid for the basket of flowers}=7+0.28[/tex]
[tex]\text{The total price that Brandon paid for the basket of flowers}=7.28[/tex]
Therefore, the total price paid by Brandon for the basket of flowers was $7.28.
Answer:
Total price Brandon pays for the basket of flowers is, $7.28
Step-by-step explanation:
As per the given statement: Brandon buys a basket of flowers for $7 before tax.
Convert this $7 into cents.
1 dollars = 100 cents.
$7 = 700 cents.
It is also given that the sales tax is 4%.
then;
Sales tax = [tex]4\% \times 700 = \frac{4}{100} \times 700 = 4 \times 7 =28 cents[/tex]
Total price Brandon pays = Price of Brandon buys a flower before tax + sales tax price
= 700 + 28 = 728 cents = $7.28
Therefore, the total price Brandon pays for the basket of flowers is, $7.28

A. (4,−25)
B. (1, 1)
C. (−1, 2)
D. (0, 0)
Answer:
A and B
Step-by-step explanation:
assuming the function should be
- [tex]3^{x-1}[/tex] + 2, then
A
substitute the x value into f(x) and check the validity of the y- value
f(4) = - [tex]3^{3}[/tex] + 2 = - 27 + 2 = - 25 ← agrees with y value
(4, - 25) lies on the graph
B f(1) = - [tex]3^{0}[/tex] + 2 = - 1 + 2 = 1 ← agrees with y value
(1, 1) lies on the graph
C
f(- 1) = - [tex]3^{-2}[/tex] + 2 = - [tex]\frac{1}{9}[/tex] + 2 ≠ 2
(- 1, 2) does not lie on the graph
D
f(0) = [tex]3^{-1}[/tex] + 2 = - [tex]\frac{1}{3}[/tex] + 2 ≠ 0
(0, 0) does not lie on the graph
Alice paid $21.75 for some packs of rice crackers. If each pack costs $1.75, how many packs did she buy?
We have dollars and dollars per pack, so we divide to get how many packs.
[tex] \dfrac{21.75}{1.75} = \dfrac{2175}{175} = \dfrac{87(25)}{7(25)} = \dfrac{87}{7} \approx 12.4[/tex]
Odd that it's not a whole number of packs; please check the question carefully. Let's say she bought 12 and got some change.
My guess is the question really says Alice spent $22.75, so she bought 13 packs. Again check the question carefully. You don't need us to divide two numbers.

Find the equation for the least-squares regression line for number of assaults compared with number of robberies. ŷ = 309,552.15 + 1.31x ŷ = 1.31 + 309,552.15x ŷ = 546,641.84 + 0.64x ŷ = 0.64 + 546,641.84x Unable to determine the equation
Answer:
[tex]\hat{y}=309,552.15 + 1.31x[/tex]
Step-by-step explanation:
The equation for the least-squares regression is,
[tex]\hat{y}=a+bx[/tex]
where b is the slope and a is the intercept.
They can be found out by,
[tex]b=r\cdot \dfrac{SD_y}{SD_x},\\\\a=\overline{y}-b\overline{x}[/tex]
where,
r = correlation coefficient = 0.84
[tex]SD_y[/tex] = standard deviation of y = 44,910
[tex]SD_x[/tex] = standard deviation of x = 28,803
[tex]\overline{y}[/tex] = mean of y = 774,140
[tex]\overline{x}[/tex] = mean of x = 354,718
Putting the values,
[tex]b=0.84\cdot \dfrac{44910}{28803}=1.309\approx 1.31[/tex]
[tex]a=774140-(1.31\times 354718)\approx 309,552.15[/tex]
Therefore the equation is,

Dan paid $34.30 for a sweater the price included a 40% markup what is the cost of the sweater before the markup
Answer:
$24.5
Step-by-step explanation:
Let x be the cost of sweater before markup.
We are told that Dan paid $34.30 for a sweater the price included a 40% markup. This means x plus 40% of x equals 34.30.
We can represent this information as:
[tex]x+\frac{40}{100}x=34.30[/tex]
[tex]x+0.40x=34.30[/tex]
[tex]1.40x=34.30[/tex]
[tex]x=\frac{34.30}{1.40}[/tex]
[tex]x=24.5[/tex]
Therefore, the cost of sweater before the markup was $24.5.
