A local bicycle shop makes $75 on each
Model A bike and $90 on each Model B bike.
The overhead costs for making the bikes are
$1,350. Write an inequality to show how
many of each bike model must be sold so the
company avoids losing money.

Answers

The inequality that show how many of each bike model must be sold so the

company avoids losing money is 75x + 90y ≥ $1350

Let x represent the number of model A bikes produced and y represent the number of model B bikes produced.

Since A local bicycle shop makes $75 on each Model A bike and $90 on each Model B bike, hence:

Revenue = 75x + 90y

The overhead cost is $1350, hence to make profit:

Revenue ≥ cost

75x + 90y ≥ $1350

The inequality that show how many of each bike model must be sold so the

company avoids losing money is 75x + 90y ≥ $1350

Which equation can be used to describe the relationship between x and y shown in the table below?

Answers

Answer:

y = 3x/2 + 24

Step-by-step explanation:

y = ax + b

⇒ 6 = -12a + b

9 = -10a + b

⇒ 2a = 3, a = 3/2

⇒ b = 24

⇒ y = 3x/2 + 24

A student was marked tardy five different times in a 40 day period. What percent of the time was the student tardy?

Answers

Answer:

12.5%

Step-by-step explanation:

5/40 = .125

.125×100 = 12.5%

The percentage is the indicating hundredth. The percentage of times the students marked will be 12.5%.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

A student was marked tardy five different times in a 40-day period.

Percentage of 5 among 40 →

(5/40) x 100 = 12.5%

The two angle are internal alternate relative to the two parallels, so they have the same measure.

[tex]-8x+8 = -6x+20\\-2x=12 \rightarrow x = -2[/tex]

Answer:

x = -6

Step-by-step explanation:

The two angles given are alternate angles - this means they are equal. Therefore:

-8x + 8 = -6x + 20

We can solve this by first putting all the x's on one side and the numbers on the other side:

-8x + 6x = 20 - 8

Now we can simplify both sides down:

-2x = 12

Finally divide both sides by -2 to get x on its own:

x = -6

A. y= 2/3x + 9
B. y= -2/3x + 1
C. y= -3/2x - 4
D. y= -3/2x + 3/2

Answers

Answer:

Step-by-step explanation:

I had this question before

Answer:

C. y= -3/2x - 4

Step-by-step explanation:

Option 2, y=-3/2x-4

Step-by-step explanation:

Solve with the point-slope formula: y-y1=m(x-x1). The line is perpendicular, meaning the slope of the new equation will be the oppposite reciprocal of the original slope.

First, we need to rewrite the original equation into standard form.

2x-3y=13

-3y=13-2x

y=-13/3+2/3x

From this, we can see that the slope here is 2/3. Since the line we're looking for is perpendicular, the opposite reciprocal of that slope is -3/2.

Now, we can plug in the coordinates we have into the formula (-6, 5), along with our slope (-3/2).

y-(5)=-3/2(x+6)

y-5=-3/2x-9

y=-3/2x-4

And to check, we can just plug the coordinates into our new equation:

Check:

(5)=-3/2(-6)-4

5=9-4

5=5

the rectangle with a side of length 12cm has a diagonal of 15cm. what is the perimeter of the rectangle?

Answers

Answer: 42 cm

Step-by-step explanation:

First since the second side length is unknow we need to find it.

We will use the Pythagorean theorem which is [tex]a^{2} + b^{2} = c^{2}[/tex]

Since we will be solving for b we will rearrange the equation to be

[tex]b^{2} = a^{2} - c^{2}[/tex]

now to slove input the data we know

[tex]b^{2}[/tex] = 144 - 225

[tex]b^{2}[/tex] = 81

[tex]\sqrt{b^{2} } = \sqrt{81}[/tex]

[tex]b[/tex] = 9

With the two sides we simply add up all the sides for the perimeter

9+12+9+12 = 42
