Ethan and Sam work at different department stores. Ethan is paid 125$ per week and an 8% commission on sales, while Sam is paid 200$ per week and a 6% commission on sales. Enter the amount in dollars of sales for which they earn the same weekly income

Answers

Answer:

3750$

Step-by-step explanation:

Let x be the amount in dollars of sales:

125 + 0.08x = 200 + 0.06x (when Ethan and Sam earn the same weekly income)

0.02x = 75

x = 3750

Suki rode her bike 6/7 mile. Claire rode her bike 1/3 mile. They want to compare how far they each rode their bikes using benchmark 1/2. Select the correct answer to describe how to solve the problem.

Answers

Answer:

6/7 > 1/2

1/3 < 1/2

Suki rode her bike a longer distance than Clarie

Step-by-step explanation:

Suki's distance = 6/7 miles

Compare with bechmark 1/2

6/7 and 1/2

Make the denominators same

(6*2)/(7*2) and (1*7)/(2*7)

12/14 and 7/14

12/14 is greater than 7/14

12/14 > 7/14

Therefore, 6/7 > 1/2

Clarie distance = 1/3 miles

Compare with bechmark 1/2

1/3 and 1/2

Make the denominators same

(1*2)/(3*2) and (1*3)/(2*3)

2/6 and 3/6

2/6 is less than 3/6

2/6 < 3/6

Therefore,

1/3 < 1/2

Compare Suki's distance with Clarie

compare 6/7 and 1/3

Make the denominators same

(6 * 3)/(7 * 3) and (1 * 7)/(3 * 7)

18/21 and 7/21

18/21 > 7/21

Suki rode her bike a longer distance than Clarie

plss helppp

Answers

Answer: 3 radians (choice C)

==============================================

Work Shown:

L = arc length = 12 cmtheta = angle in radians = unknownr = radius = 4 cm

L = theta*r

12 = theta*4

12/4 = theta

3 = theta

theta = 3 radians, choice C is the answer.

--------

Side note: The formula L = theta*r only works if theta is in radians.

If theta is in degrees, then use L = (theta/360)*2pi*r. So you can see that radian mode is much easier in this case.

Surface area of cubic box = 376 square inch

Step-by-step explanation:

Given:

Using net diagram

Length of cubic box = 10 inches

Width of cubic box = 6 inches

Height of cubic box = 8 inches

Find:

Surface area of cubic box

Computation:

Surface area of cuboid = 2[(lb) + (bh) + (hl)]

Surface area of cubic box = 2[(10)(6) + (6)(8) + (8)(10)]

Surface area of cubic box = 2[60 + 48 + 80]

Surface area of cubic box = 2[188]

Surface area of cubic box = 376 square inch

Josh lit a 14 in candle. She noticed that it wad getting an inch shorter every 30 minutes. Write an equation in y=mx+b form to medel this situation. Let x be the number of hours and y be the total height of the candle

Answers

Answer:

y = -1/30x + 14

Step-by-step explanation:

Height (changing by -1) is the dependent variable, therefore is represented by y

Time (changing by +30) is the independent variable, therefore is represented by x

14 = where we started from

Slope = Change in y / Change in x

Slope = -1/30x

Equation = -1/30x + 14

Radius= diameter ÷2

Rdaius of sphere

Write the equation of the line, in slope-intercept form y=mx+b, that has a slope of 9 and a y-intercept of -3.

Answers

Step-by-step explanation:

We are supposed to write the equation in slope intercept form of a line . Firstly we know the slope intercept form as ,

[tex]\implies\sf y = mx + c [/tex]

Where ,

m is the slope c is the y Intercept .

Now by question , the given data is ,

m = 9 c = -3

On substituting the respective values we have ,

[tex]\sf\implies y = 3 * x + (-3)\\\\\sf\implies\red{ y = 3x - 3 } [/tex]

Hence the slope intercept form is y = 3x - 3 .

Shawn wants to buy a bowling ball that typically costs $120. Currently, the bowling ball is on sale for 13% off. As a member of the bowling league, Shawn is also entitled to an additional 15% discount off the sale price of the bowling ball. If the sales tax in Shawn's state is 7.5%, what is the final price that Shawn will have to pay for the bowling ball?

Answers

Answer:

95.40

Step-by-step explanation:

120x.13=15.60. discount

120-15.60=104.40 sales price

104.40x.15=15.66 additional discount

104.40-15.66=88.74 additional sales price

88.74x.075=6.66 sales tax

what should be subtracted from (1/2+1/3+1/4) to get -2

Answers

1/2 + 1/3 + 1/4 - x = - 2

6/12 + 4/12 + 3/12 - x = - 2

6 + 4 + 3 / 12 - x = - 2

13/12 - x = - 2

x = 13/12 + 2

x = 13/12 + 24/12

x = 37/12 Or x = 3 1/12

Answer:

x = 37/12 Or x = 3 1/12

Step-by-step explanation:

1/2 + 1/3 + 1/4 - x = - 2

6/12 + 4/12 + 3/12 - x = - 2

6 + 4 + 3 / 12 - x = - 2

13/12 - x = - 2

x = 13/12 + 2

x = 13/12 + 24/12

x = 37/12 Or x = 3 1/12

A square is changed into a rectangle by increasing the length of the square by 5 units to be (x + 5) and increasing the width by 3 units to be (x + 3). Write a simplified expression that represents the area of the resulting rectangle in square units?

Answers

Area of the rectangle = x^2 + 8x + 15 square units

Explanation:

Length = x + 5
Breadth = x + 3

Area = l x b = (x + 5)(x + 3) = x(x + 3) + 5(x + 3) = x^2 + 3x + 5x + 15 = x^2 + 8x + 15 square units

Suppose that the width of a rectangular garden is (6 − 2√3) ft. And the length of the garden is (3 + √3) ft. (a) Find the area of the garden in simplest radical form. (2 points)

Answers

Answer:

A = 12 feet²

Step-by-step explanation:

Given that,

The width of a rectangular garden is (6 − 2√3) ft.

The length of the garden is (3 + √3) ft.

We need to find the area of the garden. The area of a rectangle is given by :

A = lb

Put all the values,

A = (6 − 2√3)(3 + √3)

A = 12 feet²

So, the area of the garden is equal to 12 feet².
