Harper works at an electronics store as a salesperson. Harper earns a 6% commission on the total dollar amount of all phone sales she makes, and earns a 5% commission on all computer sales. Harper made a total of $2600 in sales and earned $137 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Harper made and the dollar amount of computer sales she made. Define the variables that you use to write the system.
Answers
Answer:
The system of equations are
x + y = 2600 …….equation (1)
and, 6x + 5y = 13700 ……equation (2)
Explanation:
Let x = amount of sales of phone;
y = amount of sales of computer
For phone, 6% of sales is 6% of x, or 6% * x = 0.06x.
Similarly for computer,
5% of y = 0.05y
Given the total sales; x + y = 2600
And commission; 0.06x + 0.05y = 137; or 6x + 5y = 13700
Therefore the system of equations are
x + y = 2600 …….equation (1)
6 x + 5 y = 13700 ……equation (2)
Lance and Mary are buying a piece of property. The property cost $64,975. The bank is requiring a 20% down payment. About how much money will they need for a down payment?
Answers
Lance and Mary will need approximately $12,995 for a down payment on the property.
Explanation:To calculate the amount of money needed for a down payment, you need to find 20% of the property cost. In this case, the property cost is $64,975.
Step 1: Convert 20% to a decimal by dividing it by 100: 20/100 = 0.2
Step 2: Multiply the property cost by 0.2: $64,975 * 0.2 = $12,995
Therefore, Lance and Mary will need approximately $12,995 for a down payment on the property.
A groundskeeper needs grass seed to cover a circular field 290 feet in diameter
A store sells 50 pins bags of grass seed. One pound of grass seed covers about 400 square feet of field.
What is the smallest number of bags the groundskeeper must buy to cover the circular field?
Answers
Answer:
165
Step-by-step explanation:
First we need to find the area of the field, A = r^2 * pi
The radius is 290 / 2 = 145 feet
A = 145 * 145 * 3.14 = 66018.5 sqr feet
One bag covers 400 sqr feet
Divide the Area by 400 sqr feet to find number of bags needed.
66018.5 / 400 = 165
He will need at least 165 bags to cover the field
Answer:
4 bags
Step-by-step explanation:
We need to find the area of the circular field. To do this, we use the formula
A=piR^2 (pi multiplied by radius squared)
The radius is going to be 290/2 which is 145 which we plug into the equation.
A=pi145^2
The next step is to square 145, getting 21025. But now we need to multiply that by pi (3.14). We get 66018.5 as the answer.
Now we need to figure out how many square feet one bag can cover. To do this, we multiply 400 by 50 (because one pound can cover 400ft and one bag has 50 pounds). We get 20000 as the amount one bag of grass seed can cover. Now we need to divide 66018.5 by 20000. We get 3.300925. But the groundskeeper can't buy a decimal of a bag so we have to round up to 4 bags of grass seed.

1.25×4+3×2 divided By (1/2) third power
Answers
Answer:
(1.25×4+3×2 )/((1/2)^3) = 88
Step-by-step explanation:
The solution to the equation 1.25×4+3×2 divided By (1/2) third power is 53 applying the order of operation PEMDAS.
Explanation:To solve 1.25×4+3×2 divided By (1/2) third power, we first have to follow the order of operation, that is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), also known as PEMDAS.
Step 1: Solve the expressions in parentheses and the exponent. As there's none, we move to the next step.
Step 2: Solve the multiplication and division.
1.25×4 equals 5, then 3×2 equals 6, and then 1/2, to the third power, equals 0.125.
So our equation now reads 5+6 divided by 0.125.
Step 3: Execute the division operation. 6 divided by 0.125 equals 48.
Our equation now reads 5 + 48.
Step 4: The last step is addition. 5 + 48 equals 53. So, the answer to the equation 1.25×4+3×2 divided By (1/2) third power is 53.

A women bought some large frames for $16 each and some small frames for $9 each at a close out sale. If she bought 16 frames for $165, find how many of each type she bought.
Answers
Answer:
3 large, 13 small
Step-by-step explanation:
large: x
small: y
x + y = 16
16x + 9y = 165
Multiply first equation by 9 and subtract the equations.
9x + 9y = 144
-(16x + 9y = 165)
-7x = -21
x = 3
Now substitute this x value into the first equation
x + y = 16
3 + y = 16
y = 13
you begin with $90 in your savings account and your friend begins
with $35 in her savings account. You deposit $10 in savings each
week, and your friend deposits $15 in savings each week.
a. Write and graph a system of linear equations that
represent the amounts in each of your savings
accounts
b. Your friend says that in 10 weeks you will both
have the same amount of money in your savings
accounts. Is your friend correct? Use the graph
from part (a) to explain your answer.
Answers
Answer:
F(f) = 15t + 35 represents the total amount of savings your friend would make in t weeks.
F(d) = 10t + 90 represents the total amount of saving you, darian, would make in t weeks.
When you graph the equations, plugging in different values for t, you can see that the graphs intersect at (11,200). This means that at 11 weeks, both you and your friend have the same amount of money saved up, $200. They will not have the same amount of money in 10 weeks.
Answer:
a. [tex]y=10x+90[/tex][tex]y=15x+35[/tex]
b. Your friend is wrong.Step-by-step explanation:
If you begin with $90 and add $10 each week, then we express it as
[tex]y=10x+90[/tex]
Where [tex]x[/tex] refers to weeks and [tex]y[/tex] refers to the total amount of money in you savings account.
On the other hand, your friend begins with $35 and deposits $15 each week, the equation that expresses your friend's savings is
[tex]y=15x+35[/tex]
Therefore, the sytem of linear equation that models this situation is
[tex]y=10x+90[/tex]
[tex]y=15x+35[/tex]
The graph attached shows this system. There you can notice that the solution is (11, 200), which means in 11 weeks both will have the same amount saved.
Therefore, your friend is wrong, because after 10 weeks you won't have the same amount.

The diagram shows the rectangle with vertices at A(3,4), B(3,7), C(4,7) and D(4,4).
1. Rotate rectangle ABCD by 180° about the point (3,4) (vertex A). This rotation has the rule:
[tex](x,y)\rightarrow (6-x,8-y)[/tex]
So, the image points have the coordinates A'(3,4), B'(3,1), C'(2,1) and D'(2,4)
2. Dilate by a scale factor of 2 with the center of dilation at origin. This dilation has the rule:
[tex](x,y)\rightarrow (2x,2y)[/tex]
So, the image points have the coordinates A''(6,8), B''(6,2), C''(4,2) and D''(4,8)
3. Reflect it over the y-axis. This reflection has the rule:
[tex](x,y)\rightarrow (-x,y)[/tex]
So, the image points have the coordinates A'''(-6,8), B'''(-6,2), C'''(-4,2) and D'''(-4,8) that are exactly the coordinates of the second rectangle shown.

Keith has $500 in a savings account at the beginning of the summer. He wants to have at least $200 at the end of the summer. He withdraws $25 per week for food. How many weeks can Keith withdraw money from his account?
Answers
Keith can withdraw money from his account for 12 weeks.
Step-by-step explanation:
Total savings = $500
Amount to be left in his account = $200
Withdrawal per week = $25
Let,

According to given statement;
Total savings - Withdrawal per week * no. of weeks = Amount to be left
[tex]500-25x=200\\-25x=200-500\\-25x=-300\\[/tex]

Final answer:
Keith can withdraw money from his account for food for 12 weeks before reaching his minimum account balance requirement of $200.
Explanation:
To determine how many weeks Keith can withdraw money from his account while maintaining a balance of at least $200, we need to perform a simple subtraction and division operation. First, we calculate the amount he needs to leave in the account:
$500 initial balance - $200 desired end balance = $300 available to spend.
Keith withdraws $25 per week for food. To find out how many weeks his money will last, we divide the total amount he can spend by the weekly withdrawal amount:
$300 \/ $25 per week = 12 weeks.
Therefore, Keith can withdraw money for food for 12 weeks before his account balance reaches his minimum requirement of $200.

Answer:
x = -22 , y = -26
Step-by-step explanation:
Solve the following system:
{y = x - 4 | (equation 1)
y - 2 x = 18 | (equation 2)
Express the system in standard form:
{-x + y = -4 | (equation 1)
-(2 x) + y = 18 | (equation 2)
Swap equation 1 with equation 2:
{-(2 x) + y = 18 | (equation 1)
-x + y = -4 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{-(2 x) + y = 18 | (equation 1)
0 x+y/2 = -13 | (equation 2)
Multiply equation 2 by 2:
{-(2 x) + y = 18 | (equation 1)
0 x+y = -26 | (equation 2)
Subtract equation 2 from equation 1:
{-(2 x)+0 y = 44 | (equation 1)
0 x+y = -26 | (equation 2)
Divide equation 1 by -2:
{x+0 y = -22 | (equation 1)

Part a) Camilo is 34 years old and Juan is 28 years old
Part b) The difference between Camilo's age and Juan's age is 6 years
Part c) The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother
Step-by-step explanation:
The question in English is
If Camilo is 6 years older than Juan, Juan is 7 years younger than Andrés and Andrés is 35 years old .
Part a) How old is Camilo and how old is Juan? raises the equation.
Part b) What's the difference between Camilo's age and Juan's age?
Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?
Part a) How old is Camilo and how old is Juan? raises the equation.
Let
x -----> Camilo's age
y -----> Juan's age
z -----> Andres's age
we know that
[tex]x=y+6[/tex] -----> equation A
[tex]y=z-7[/tex] -----> equation B
[tex]z=35[/tex] -----> equation C
Find the value of y
substitute the value of z in the equation B
[tex]y=35-7=28[/tex]
Find the value of x
substitute the value of y in the equation A
[tex]x=28+6=34[/tex]
therefore
Camilo is 34 years old and Juan is 28 years old
Part b) What's the difference between Camilo's age and Juan's age?
Subtract Juan's age from Camilo's age
so
[tex]x-y=34-28=6\ years[/tex]
Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?
Adds Camilo's age and Juan's age
[tex]x+y=34+28=62\ years[/tex]
[tex]62\ years\neq 65\ years[/tex]
therefore
The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

tickets sold on Friday
Complete the table above to show the numbers of tickets sold on Saturday.
What is the total number of tickets sold over these two days?
Answers
Answer:
Number of Adult's tickets sold on Saturday = 3,356
Number of Children's tickets sold on Saturday = 2, 928
Total number of tickets sold over these two days is 8,938.
Step-by-step explanation:
Here, the number of tickets sold on FRIDAY:
Adult Ticket sold = 1,678
Children's Tickets sold = 976
So, the total number of tickets sold on Friday
= Sum of ( Adult + Children's ) tickets = 1,678 + 976 = 2,654 .... (1)
The number of tickets sold on SATURDAY:
Adult Ticket sold = 2 times the number of adult tickets sold on Friday
= 1,678 x 2 = 3,356
Children's Tickets sold = 3 times the number of children's tickets sold on Friday.
= 976 x 3 = 2, 928
So, the total number of tickets sold on Saturday
= Sum of ( Adult + Children's ) tickets = 3,356 + 2,928 = 6, 284 .... (2)
Now, the total number of tickets booked in these two days :
Sum of tickets booked on (Friday + Saturday)
= 2,654 + 6, 284 = 8,938
Hence, total number of tickets sold over these two days is 8,938.

Answers
Answer:
The speed of Sharma is slower than the speed of Brandi
I.e ∵ 4.67 miles per hour [tex]<[/tex] 5 miles per hour
∴ [tex]S_2[/tex] [tex]<[/tex] [tex]S_1[/tex]
Step-by-step explanation:
Given as :
The distance cover by Brandi = [tex]D_1[/tex] = 2 [tex]\frac{1}{2}[/tex] =[tex]\frac{5}{2}[/tex]
The Time taken by Brandi for jogging = [tex]T_1[/tex] = 30 minutes =[tex]\frac{1}{2}[/tex] hour
Let the speed of Brandi = [tex]S_1[/tex] = [tex]\dfrac{\textrm Distance }{\textrm Time}[/tex]
or, [tex]S_1[/tex] = [tex]\dfrac{\textrm [tex]D_1[/tex] }{\textrm [tex]T_1[/tex] }[/tex]
Or. [tex]S_1[/tex] = [tex]\frac{\frac{5}{2}}{\frac{1}{2}}[/tex]
∴ [tex]S_1[/tex] = 5 miles per hour
Again
The distance cover by Sharma = [tex]D_2[/tex] = 3 [tex]\frac{1}{2}[/tex] =[tex]\frac{7}{2}[/tex]
The Time taken by Sharma for jogging = [tex]T_2[/tex] = [tex]\frac{3}{4}[/tex] hour
Let the speed of Sharma = [tex]S_2[/tex] = [tex]\dfrac{\textrm Distance }{\textrm Time}[/tex]
or, [tex]S_2[/tex] = [tex]\dfrac{\textrm [tex]D_2[/tex] }{\textrm [tex]T_2[/tex] }[/tex]
Or. [tex]S_2[/tex] = [tex]\frac{\frac{7}{2}}{\frac{3}{4}}[/tex]
∴ [tex]S_2[/tex] = [tex]\frac{14}{3}[/tex] = 4.67 miles per hour
Now, ∵ 4.67 miles per hour [tex]<[/tex] 5 miles per hour
∴ [tex]S_2[/tex] [tex]<[/tex] [tex]S_1[/tex]
So, Sharma jogged at slower late
Hence The speed of Sharma is slower than the speed of Brandi Answer
