B. 1/4
Step-by-step explanation:
Ms. Sloane earns an 8% commission on her total sales. In February, Ms. Sloane's total sales were $29,250. In March, Ms. Sloane's total sales were $32,725. How much more money, in dollars, did Ms. Sloane earn in commission in March than she earned in February? Enter your answer in the box. nos
Answer:
$278
Step-by-step explanation:
8% of 29,250 = 2340
8% of 32,725 = 2618
2618 - 2340 = 278
she earned $278 dollars more in march than in february.

Please help me i dont know how to do this!!
Answer:
-1/2 is m and 3 is b
Step-by-step explanation:
-1/2 is the slope and 3 is the y-intercept,
Answer:
Step-by-step explanation:
The slope m is -1/2
The y-int b is 3
Since the slope is negative the graph should start from the top left and should go down all the way down to the bottom right. The line should also pass the point (0,3) since 3 is the y-int

The starting line for a race in Pike is 2.4 miles from the finish line. On a map of the course, the starting and finish lines are 1 inch apart. What scale does the map use?
Explain how I solve it?
Answer:
The scale factor is 152,064:1
Step-by-step explanation:
Scaling
The real distance of a race track in Pike is 2.4 miles.
One mile is equivalent to 63,360 inches, thus 2.4 miles = 152,064 inches.
On a map, that very same distance is represented as 1 inch. Thus the scale factor is 152,064:1
This means every inch on the map is equivalent to 152,064 inches on the race track.

Find the equation of a line given 2 coordinates (5, 5) and (-2, -2)
if you could write the equation and show work that would be great!! whoever answers and is correct i WILL mark brainliest :)
Answer:
y=x
Step-by-step explanation:
using slope intercept form and slope formula so y=x
Answer:
y=mx+c
x co-ordinates is 5 & -2
y co-ordinates is 5 & -2
m is the gradient so you have to do change in y over change in x (basically the difference in the y axis )
so change in y : (-2)-5 = -7
change in x: (-2)-5= -7
so divide this and you get 1 which is m
Now the equation is y= 1x+C but x=1 theoretically
therefore all you do now is substitute the values onto the equation to find C. ALWAYS USE THE SAME SET OF COORDINATES.
5=1(5)+ C
5=5+C
C= 0
equation is y=x

7x2+6=23x
a. What is the first step when solving this quadratic equation?
b. What are the solutions to the equation?
Answer:
x = 3, x = [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
(a)
The first step is to subtract 23x from both sides, that is
7x² - 23x + 6 = 0 ← in standard form
(b)
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 7 × 6 = 42 and sum = - 23
The factors are - 21 and - 2
Use these factors to split the x- term
7x² - 21x - 2x + 6 = 0 ( factor the first/second and third/fourth terms )
7x(x - 3) - 2(x - 3) = 0 ← factor out (x - 3) from each term
(x - 3)(7x - 2) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
7x - 2 = 0 ⇒ 7x = 2 ⇒ x = [tex]\frac{2}{7}[/tex]
Can someone just solve the problem please? it has to be an inequality in the equation
Answer:
(A) Let a represent the number of hours Cassie needs to work
(B) The inequality is 10 × a + 30 ≥ 140
(C) a ≥ 11
(D) Cassie needs to work babysitting for her neighbor for at least 11 hours to be able to buy the graphing calculator
Step-by-step explanation:
The least amount Cassie needs for the graphing calculator = $140
The amount Cassey currently have saved = $30
The amount her neighbor offers for her to babysit = $10 per hour
(A) The definition of the variable is given as a = The number of hours Cassie needs to work
(B) The inequality that defines the situation is 10 × a + 30 ≥ 140
(C) Solving the inequality gives;
10 × a + 30 ≥ 140
10 × a ≥ 140 - 30
∴10 × a ≥ 110
a ≥ 110/10
∴ a ≥ 11
Which gives;
The number of hours Cassie needs to work = a ≥ 11 hours
(D) The solution means that Cassie needs to babysit for her neighbor for at least 11 hours to be able to buy the graphing calculator.

Answer:
y = ⅔x - 5
Step-by-step explanation:
The line that is parallel to 2x - 3y = 24, would have the same slope as the line, 2x - 3y = 24.
Rewrite;
2x - 3y = 24
-3y = -2x + 24
Divide both sides by -3
y = ⅔x - 8
Thus, the slope of 2x - 3y = 24 is ⅔.
Therefore the line that is parallel to 2x - 3y = 24, will have a slope (m) of ⅔.
Using point-slope form, we can generate an equation that passes through (-3, -7) and is parallel to 2x - 3y = 24.
Thus, substitute (a, b) = (-3, -7) and m = ⅔ into y - b = m(x - a)
Therefore:
y - (-7) = ⅔(x - (-3))
y + 7 = ⅔(x + 3)
Rewrite in slope-intercept form.
Multiply both sides by 3
3(y + 7) = 2(x + 3)
3y + 21 = 2x + 6
3y = 2x + 6 - 21
3y = 2x - 15
Divide both sides by 3
y = ⅔x - 5

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the trigonometric equation be represented as A
sin ( x/2 ) + cos ( x ) - 1 = 0
sin ( x/2 ) - ( 1 - cos ( x ) ) = 0
On further simplification , we get
( 1 - cos ( x ) ) = 2sin² ( x/2 )
So , sin ( x/2 ) - 2sin² ( x/2 ) = 0
Taking sin ( x/2 ) as the common factor , we get
sin ( x/2 ) ( 1 - 2sin ( x/2 ) ) = 0
So , the solutions to the equation are
sin ( x/2 ) = 0
x = 0 , 2π
And , ( 1 - 2sin ( x/2 ) ) = 0
sin ( x/2 ) = 1/2
x = π/3 , 5π/3
Hence , the solutions are x = 0 , π/3 , 5π/3

In Coachella, California the temperature was 9 degrees below zero at 2 am. By 5 am the temperature had dropped by an additional 7 degrees. By 1 pm the next day the temperature had risen by 12 degrees. What was the temperature at 5 am
Answer:
The temperature at 5 am is 16 degrees below zero.
Step-by-step explanation:
The temperature at 2 am is 9 degrees below zero:
[tex]T_{2_{am}} = -9 [/tex]
Since at 5 am the temperature had dropped by an additional 7 degrees, we have:
[tex]T_{5_{am}} = T_{2_{am}} - 7 [/tex]
[tex]T_{5_{am}} = -9 - 7 = -16 [/tex]
Therefore, the temperature at 5 am is 16 degrees below zero.

Marcus solved a problem and found out that 190% of 20 is 380. Is he correct
Answer: He is Incorrect, It's 38
Work: For this question, I did the Cross-Product Method. The Cross Product Method is when you solve equation via to fractions. With the CPM, One one side of the fraction, I had x / 20 (Twenty being the whole number) and on the other side, I had 190/100 (190 being the percent) After setting this up, I made the equation. 190 times 20 is 3800, and the other multiplication is 100 times x which is 100x. So, the new equation is 3800 = 100x. I divided both sides by 100, and the answer is 38 = x
I hope this helps, and Happy Holidays! :)
Answer:
No, Marcus is not correct. He converted the percent to a decimal correctly and he multiplied correctly, but he put the decimal in the wrong place in the answer. There should be two decimal places in the answer, so the answer should be 38.
