Sarah earns $20 a day working after school. She spent 30% of her daily earnings on Monday. How much money did she spend on Monday?
Answer:
$6.0
Step-by-step explanation:
If she only worked 1 day and had $20, then the answer is
20 * 3% = 20 * .3 = $6.0
Answer:
Hi! I believe the answer is 6$
Step-by-step explanation:
If you are trying to get 30% of 20, you divide 20 by 30. You would then get .6666666 or 6. I double-checked my answer online!

Solving equations using Zero-Product property
Please Help! and i need an explanation... i just don't understand and my teacher didn't explain
2y(-8y+7)=0
Answer:if y=0
Step-by-step explanation: view y as 0, so you have 2*0*(-8+0+7)=0
every number multiplied by 0 is 0 so 2*0 is 0 then in the brackets you will have -1. So the final line is 0*-1=0 like I said every number multiplied for 0 is 0 the equation is true for y=0
Answer:
see explanation
Step-by-step explanation:
The zero product property applies to the product of factors equal to zero
For example
a × b = 0
Since the product of the 2 numbers is zero , then one of the numbers must be zero, that is
a = 0 or b = 0
This can be applied to the product
2y(- 8y + 7) = 0
The 2 values being multiplied are 2y and (- 8y + 7)
Thus one or the other must equal zero, so solve both
2y = 0 ⇒ y = 0, or
- 8y + 7 = 0 ⇒ - 8y = - 7 ⇒ y = [tex]\frac{-7}{-8}[/tex] = [tex]\frac{7}{8}[/tex]
which equation is true
Answer:
A
Step-by-step explanation:
Well, this isn't too hard.
Since the left is the negative side (R) and the right is the positive side (S), a positive and a negative with the same number will equal zero if only one of them are negative.
You ALWAYS subtract when there's two different signs.

Veronica saved up her tutoring money to buy video games. She buys 2 games for $30.00 each and a game controller for $19.59. Veronica lives in San Jose, California, where sales tax is 9.25%. Which of these gives the correct amount of sales tax AND the total (with tax included)? If necessary, round the amount of tax to the nearest 100th.
Answer: See explanation
Step-by-step explanation:
Since Veronica buys 2 games for $30.00 each and a game controller for $19.59. The total cost to be paid will be:
= (2 × $30.00) + $19.59
= $60.00 + $19.59
= $79.59
Since Veronica lives in San Jose, California, where sales tax is 9.25%, the sales tax will be:
= 9.25% × $79.59
= 0.0925 × $79.59
= $7.36
Total amount paid = $79.59 + $7.36 = $86.95

A piece of Styrofoam has a charge of -0.004 C and is placed 3.0 m from a piece of salt with a charge of -0.003 C. How much electrostatic force produced?
And please show work of how you got the answer pls :)
Given that,
Charge q₁ = -0.004 C
Charge q₂ = -0.003 C
Distance between charges, d = 3 m
To find,
The electrostatic force between charges.
Solution,
The formula for the electrostatic force is given by :
[tex]F=\dfrac{kq_1q_2}{d^2}\\\\F=\dfrac{9\times 10^9\times 0.004 \times 0.003 }{(3)^2}\\\\=12000\ N[/tex]
So, 12000 N of electrostatic force is produced.
This question is based on the concept of electrostatic.Therefore, the electrostatic force produced is 12000 N.
Given:
Charge q₁ = -0.004 C
Charge q₂ = -0.003 C
Distance between charges, d = 3 m
We need to determined the how much electrostatic force produced.
According to the question,
By using the formula for the electrostatic force is given by :
[tex]F = k \dfrac{q_1 \; q_2}{d^2} \\\\F = \dfrac{9 \times 10^9 \times 0.004 \times 0.003 }{3^2} \\\\\bold{F= 12000 \; N} \\[/tex]
Therefore, the electrostatic force produced is 12000 N.

Write the rule for the linear function. Remember a function rule is written using f(x)
Answer:
The rule for the linear function will be:
[tex]f(x) = -2x+5[/tex]
Step-by-step explanation:
We know that linear function can be represented using the slope-intercept formula
y = mx+b
where m is the slope and b is the y-intercept
Given the function is linear
Taking two points from the table to determine the slope
(1, 3)(2, 1)[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:3\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)[/tex]
[tex]m=\frac{1-3}{2-1}[/tex]
[tex]m=-2[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -2 and the point (1, 3)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 3 = -2 (x-1)[/tex]
[tex]y-3 = -2x+2[/tex]
adding 3 to both sides
[tex]y-3+3 = -2x+2+3[/tex]
[tex]y = -2x+5[/tex]
or
[tex]f(x) = -2x+5[/tex]
Therefore, the rule for the linear function will be:
[tex]f(x) = -2x+5[/tex]

Is this a function?
{(2, 4), (2,5), (2,6), (2,7)}
Answer:
No
Step-by-step explanation:
For a relation to be a function it must have a unique x-value for every y-value. This means that in a function x-values cannot repeat. In this relation, the x-value repeats multiple times, so it is not a function. It is also a vertical line, and vertical lines can never be functions since the x-value is constant and therefore repeats.

Javier had $305 in his bank account. His bank charges a fee of $7.50 each month that a balance is below $500. If he makes no other deposits or withdrawals, how much money is in Javier’s account at the end of three months? Write an equation and solve.
Answer:
$282.5
Step-by-step explanation:
$7.50 * 3= $22.5
$22.5 is the total money that is charged from Javier's bank account.
Subtracting that from his $305, we get:
$305 - $22.5 = $282.5
Therefore, Javier has $282.5 in his bank account at the end of three months.
Hello 928747!
So Javier has $305 to begin with but his bank charges him $7.50 if he has less than $500 in his account.
305 < 500
So, since he has less than $500 he will lose $7.50
305 - 7.50 = 297.50
So after they take $7.50, he will have $297.50
but he had less than $500 for 3 months so they would take x 3 more than $7.50
7.50 x 3 = 22.50
305 - 22.50 = 282.50
After three months, Javier will have $282.50

In the diagram, AGEF and AHEF are congruent. What is the value of x? A. 60 B. 41 C. 28 D. 30
Answer: C) 28
Explanation:
The triangles are congruent, so the corresponding pieces are congruent. Specifically the angles on the right side are congruent, as shown by the tickmarks they have in common.
Set those two expressions equal to one another. Solve for x.
2(x+2) = 60
2x+4 = 60
2x = 60-4
2x = 56
x = 56/2
x = 28
The correct value of the variable x is,
⇒ x = 28

You are the manager at an amusement park. The park's maximum capacity is 4500 people. You have also worked out that there needs to be 2800 people in the park to make a profit after all the overhead costs and employee pay. If people are entering the park at a rate of 12 people a minute and there are 850 people in the park currently, between how many minutes should the door stay open to let guests in?
Answer:
if you need the compound equality it is 2800 ≤ 850 + 12m ≤ 4500
Step-by-step explanation:
m= minutes 2800 is the minimum 4500 is the maximum 850 is from the people already in the park and 12m came from the people coming in per minute so i multiplied the 12 by m

Lets use the quadratic formula → [tex]x = \frac{-b + \sqrt{b^{2} - 4ac} }{2a} \:or \frac{-b - \sqrt{b^{2}- 4ac } }{2a}[/tex]
So ,
[tex]x = \frac{(-2) + \sqrt{(2)^{2} - (4\times1\times-5) } }{2\times1} \:or \frac{(-2) - \sqrt{(2)^{2} - (4\times1\times-5) }}{2\times1}[/tex]
[tex]=> x = \frac{-2 + \sqrt{24} }{2} \:or \frac{-2-\sqrt{24} }{2}[/tex]
[tex]=> x = \frac{-2 + 2\sqrt{6} }{2} \:or \frac{-2 - 2\sqrt{6} }{2}[/tex]
Lets take 2 common from numerator.
[tex]=> x = \frac{2(-1 + \sqrt{6}) }{2} \:or \frac{2(-1-\sqrt{6}) }{2}[/tex]
Cancelling 2 from numerator & denominator gives
[tex]x = (-1+\sqrt{6} ) \: or (-1 - \sqrt{6} )[/tex]
