Mae Ling earns a weekly salary of $365 plus a 7.5% commission on sales at a gift shop. How much would she make in a work week if she sold $4,900 worth of merchandise?
Answer:
$732.5
Step-by-step explanation:
Mae Ling earns a weekly salary of $365 which means salary per week is $365
Then plus a 7.5% commission on sales at a gift shop if she sold $4,900 worth of merchandise, which means additional
(0.075×4900)=367.5
The total she make will be
367.5+365
=$732.5
Therefore,she will make $732.5 in a work week if she sold $4,900 worth of merchandise

Une gratification est partagée en quatre employés - le premier reçois 150euro - le seconde reçois 7/20 de la gratification -le troisieme reçois 5/28 de la gratification - le quatrième reçois le 9/35 de la gratification a) Quel est le montant de la gratification ? b) Quel est la part reçu par le premier ? c) Quel est le montant reçu par chaque employés
Explication étape par étape:
Soit la gratitude totale x
Montant reçu par le premier employé = 150 euros
Si le second reçoit 7/20 de la gratification, alors;
Deuxième reçoit = 7/20 × x
Si le troisième reçoit 5/28 de la gratification, alors
Le troisième reçoit 5/28 × x -
Si le quatrième reçoit le 9/35 de la gratification, alors;
Le quatrième reçoit 9/35 × x
Il faut ensuite calculer le pourboire total x.
Résumer tout le montant reçu
7x / 20 + 5x / 28 + 9x / 35 +150 = x
0,35x + 0,179x + 0,257x + 150 = x
0,786x + 150
x-0,786x = 150
0,214x = 150
x = 150 / 0,214
x = 700,9 euros
2) Pour obtenir le partage collecté par le premier, nous utiliserons l'expression
X × 700,9 = 150
x = 150 / 700,9
x ≈ 15/70
x≈ 3/14
D'où le premier a recueilli environ 3/14 de la gratification totale.
2) seconde collectée 0,35x
= 0,35 × 700
≈245 euros
Le troisième a recueilli 5/28 de x
Le troisième a collecté 5/28 × 700
= 3500/28
= 125 euros
Le quatrième a recueilli 9/35 de x
= 9/35 × 700
= 6300/35
≈ 180 euros
Find the slope (-3, 7) and (0, - 2)
Can show steps too please I’ll mark u brainliest
Answer:
The answer is -3
Step-by-step explanation:
Slope means the rate of change of a line which is the letter m. Whenever you need to find slope remember this: m= y2-y1 over x2-x1.
(x1,y1)= (-3,7), ( x2, y2) = (0,-2) so the slope is -3.

Answer:
[tex]=\frac{2a^4}{3bd}[/tex]
Step-by-step explanation:
Given expression is,
[tex]\frac{2ab^{-1}}{3a^{-3}d}[/tex]
Further simplify the expression by converting the negative exponents into positive.
[tex]b_1=\frac{1}{b}[/tex]
[tex]a^{-3}=\frac{1}{a^3}[/tex]
By substituting these terms in the given expression,
[tex]\frac{2ab^{-1}}{3a^{-3}d}=\frac{2a(\frac{1}{b})}{3(\frac{1}{a})^3d}[/tex]
[tex]=\frac{\frac{2a}{b}}{\frac{3d}{a^3} }[/tex]
[tex]=\frac{2a}{b}\times \frac{a^3}{3d}[/tex]
[tex]=\frac{2a^4}{3bd}[/tex]
When most American’s throw away their laundry detergent bottle it has about 1/2 of an ounce of detergent left in it. Dexter’s equation, y= -1.6x+50, and Mya’s equation, y = 50(.75)x. represent how much detergent is left in their bottles after x washes. Who will throw away their laundry detergent bottle first?
Answer:
Mya’s equation
Step-by-step explanation:
Given that:
Detergent left in bottle after a certain number of washes x
Dexter’s equation,
y= -1.6x+50
Mya’s equation,
y = 50(.75)x
y = Detergent left in bottle.
Given that amount of Detergent left is about 1/2 ounces = y
For Dexter’s equation,
y= -1.6x+50
0.5 = 1.6x + 50
0.5 - 50 = 1.6x
-45.5 = 1.6x
x = 28.4375
For Mya’s equation :
y = 50(0.75)x
0.5 = 37.5x
0.5 / 37.5 = x
0.0133333 = x
Hence, Mya’s equation
Joaquín compró una docena y media de factura la docena son parte de grasa dos tercios tiene dulce de leche y el resto son medialunas cuántas son de grasa Cuánto tiene dulce de leche Cuántas medialunas compró
Answer:
2 facturas de grasa.
12 facturas con dulce de leche
4 medialunas
Step-by-step explanation:
Una docena contiene 12 facturas y media docena contiene 6 facturas. Entonces Joaquin compro un total de 18 facturas (12+6). Si la novena parte (1/9) de las facturas son de grasa entonces solo multiplicamos esta fraccion por la totalidad de las facturas.
18 * (1/9) = 2 facturas de grasa.
La cantidad de facturas que tienen dulce de leche son dos tercios (2/3) de la totalidad. Entonces multiplicamos esta fracion for la totalidad.
18 * (2/3) = 12 facturas con dulce de leche
Por final, la cantidad de media lunas es el resto de las facturas, entonces descontamos las facturas de grasa y con dulce de leche de la totalidad para saber cuantas facturas son medialunas
18 - 2 - 12 = 4 medialunas

Austin and Dylan rode their bicycles. Austin's average speed is represented by the equation d = 20t, where d is the total distance traveled in t hours. The graph below represents Dylan's average speed while riding his bicycle.
Who had the fastest average speed and by how much?
Answer:
Austin has the better average speed by 5 mph
Step-by-step explanation:
The slope of Dylan’s graph will his average speed
Let’s select two points on the graph to use
The slope can be calculated as;
m = (y2-y1)/(x2-x1)
m = (90-30)/(6-2)
m = 60/4
m = 15
So the equation for Dylan would be
d = 15t
This shows that Austin has a faster average speed by 5 mph

A runner’s resultant velocity is 8 miles per hour due west running with a wind of 3 miles per hour N 28° W. What is the runner’s speed, to the nearest mile per hour, without the effect of the wind.
Answer:
7.07 miles/hour W 22° S.
Step-by-step explanation:
Given that the resultant velocity of the runner, [tex]v_r = 8[/tex] miles/hour due west.
Wind speed, [tex]v_w= 3[/tex] miles/hour N 28° W.
Assuming that the absolute velocity of the runner, [tex]v_a= x[/tex] miles/ hour W \alpha S as shown in the figure.
By using vector addition, [tex]\vec{v_r} = \vec {v_w} + \vec {v_a}[/tex] .
Now, from the figure,
[tex]|\vec {v_r}|=|\vec {v_w} |\sin{28°} + |\vec {v_a}| \cos \alpha \\\\\Rightarrow 8 = 3\sin{28°} + |\vec {v_a}| \cos \alpha \\\\\Rightarrow |\vec {v_a}| \cos \alpha =8-3\sin{28°} \cdots(i)[/tex]
And [tex]AC= |\vec {v_w} |\cos{28°} = |\vec {v_a}| \sin \alpha \\\\[/tex]
[tex]\Rightarrow |\vec {v_a}| \sin \alpha= 3\cos{28°} \cdots(ii)[/tex]
Dividing equation (ii) by equation (i), we have
[tex]\frac {|\vec {v_a}| \sin \alpha}{|\vec {v_a}| \cos \alpha}=\frac {3\cos{28°}}{8-3\sin{28°}} \\\\\Rightarrow \tan \alpha = 0.402 \\\\\Rightarrow \alpha = \tan ^{-1} (0.402)=22^{\circ} \\\\[/tex]
Putting the value of \alpha in equation (ii), we have
[tex]|\vec {v_a}| \sin {22^{\circ}}= 3\cos{28^{\circ}} \\\\\Rightarrow |\vec {v_a}| =(3\cos{28^{\circ}})/\sin {22^{\circ}} \\\\[/tex]
[tex]\Rightarrow |\vec {v_a}| = 7.07[/tex] miles/hour
Hence, the runner speed, without the effect of the wind, is 7.07 miles/hour W 22° S.
Error Analysis Jessie incorrectly said the rate 1/4 pound 1/8 gallon can be written as the unit rate 1/32 pound per gallon what is the correct unit rate? What was Jessie's likely error?
Answer:
Step-by-step explanation:
Given that 1/4 pounds = 1/8 gallons
We are to find the unit rate per gallon, hence we will say;
x pounds = 1 gallon
Equate both expression
1/4 pounds = 1/8 gallons
x pounds = 1 gallons
Cross multiply
1/8 * x = 1/4
divide both sides by 1/8
(1/8x)/(1/8) = (1/4)/(1/8)
x = 1/4 * 8/1
x = 1/4 * 8
x = 2 pounds
Hence the unit rate per gallon is 2 pounds per gallon
Her error was that he multiplied both values together to arrive at 1/32 instead of dividing as shown in the

In a system of two linear equations, the lines represented by each equation have the same slope and different y-intercepts. Which would be the total number of solutions to the system of equations?
Answer:
There will be no common solution
Step-by-step explanation:
Given that the lines that represent the equations in the system of the two linear equations have equal slope but that their y-intercept are different, we have;
The two lines are parallel to each other
The two lines are different lines, given that they have different y-intercept
By definition of parallel lines, we have that the two lines representing the two equations will never meet, and therefore, both equations do not have a common solution which is a value that satisfies both equations
Therefore, the two equations in the linear system of equations, do not have a common solution
How do I solve this??? 15 points!
Answer:
[tex]\displaystyle y=\frac{7}{2}x-3[/tex]
Step-by-step explanation:
We wan to determine the equation of a line that passes through the point (2, 4) and is parallel to:
[tex]\displaystyle y=\frac{7}{2}x-5[/tex]
Since our new line is parallel to our equation, this means that the two lines have the same slope.
Therefore, the slope of our new line is also 7/2, the slope of the original.
Now, we can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, we will substitute 7/2 for m.
Let's let our point (2, 4) be (x₁, y₁). Hence:
[tex]\displaystyle y-4=\frac{7}{2}(x-2)[/tex]
Solve for y. Distribute:
[tex]\displaystyle y-4=\frac{7}{2}x-7[/tex]
Add 4 to both sides.Therefore, our equation is:
[tex]\displaystyle y=\frac{7}{2}x-3[/tex]
