Answer:

3.5

Step-by-step explanation:

-14/-4=3.5

Answer: the system of inequalities are

x + y ≤ 14

18x + 38y = 342

Step-by-step explanation:

Let x represent the number of iPad chargers sold.

Let y represent the number of keyboards sold.

At the end of the day, he knows he sold a maximum of 14 items. This is expressed as

x + y ≤ 14

If he

charged $18 for each iPad charger (x) and $38 for each keyboard (y) and earned a total of $342, the expression would be

18x + 38y = 342

332.64 m²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 26.4 and h = 12.6 , thus

A = 26.4 × 12.6 = 332.64 m²

Answer:

The second option you listed: x + y = 4 gives the same line as H, and therefore renders infinite number of solutions (as many as every point on the line)

Step-by-step explanation:

We need to look for the equation that exactly matches the given one :

2 x + 2 y = 8

notice dividing both sides of this equation by "2" we get:

x + y = 4

SO this equation represents exactly the same line as 2 x + 2 y = 8 does, and therefore their graphs overlap completely

Answer: 25%

Step-by-step explanation: So, I think we know it's 50% chance to get heads or tails. But what's the chance of getting heads two times in a row....let's see...

[tex]\frac{1}{2} * \frac{1}{2} = \frac{1}{4}[/tex]

Let's turn [tex]\frac{1}{4}[/tex] into a decimal...

1 ÷ 4 = 0.25

0.25 * 100 = 25

= 25%

Thus, you have a 25% to get heads two times in a row...I hope this helps!

Answer: the answer is C. 80°

Step-by-step explanation:

= 360 - 110 - 90

=160°

b=1/2 (160)

b=80°

Answer:

C. 80 degrees

Step-by-step explanation:

The measure of the given arcs are 90 and 110.

Subtract those values from 360

= 360 - 90 -110

= 160

The angle b is half of 160 degrees, the measure of the arc that intercepts it.

Therefore, it measures 80 degrees.

Answer:

97 square miles

Step-by-step explanation:

Let us divide this figure into rectangles, each of set dimensions;

[tex]Dimensions of Rectangle A - Height ; 2 mi, Length ; 9 mi\\Area of Rectangle A - Height * Length = 2 mi * 9 mi = 18 square miles,\\\\Dimensions of Rectangle B - Height ; 2 mi + 5 mi = 7 mi, Length ; 5 mi\\Area of Rectangle B - Height * Length = 7 mi * 5 mi = 35 square miles,\\\\Dimensions of Rectangle C - Height ; 4 mi + 5 mi + 2 mi = 11 mi, Length ; 4 mi,\\Area of Rectangle C - Height * Length = 11 mi * 4 mi = 44 square miles,\\\\Area of Figure = 18 + 35 + 44 = 97 square miles[/tex]

Solution; 97 square miles

Answer:

4.3

Step-by-step explanation:

Apply trigonometric ratios to find the answer.

Firstly, we need to find the measure of angle theta. In order to do this, we will use triangle BAD.

From angle theta, the trigonometric ratio sine can be used:

sinθ = [tex]\frac{4.1}{5.3}[/tex]

After we find the value, we take the inverse sine of it and the result is approximately 50.7 degrees.

Now, knowing that angles BAD and CAD are the same, we can solve for CD using trigonometric ratio sine.

sin50.7 = opposite/hypotenuse

sin50.7 = CD/5.5

sin50.7 * 5.5 = CD

4.3 ≈ CD

Answer:

-5

Step-by-step explanation:

The initial value is the value of y when x has the value of 0.

Substitute 'x' for '0' and solve for 'y':

[tex]y=-2(0)-5\\\rightarrow -2*0=0\\y=0-5\\\boxed{y=-5}[/tex]

Option A should be correct.

Answer: -5

Step-by-step explanation:

Y= -2x - 5

+2. +2

-------------

Y= x(0)-5

So the initial value would be -5 because that would be x=0. Sorry if this is complicated I havent done it since the beginning of 6th grade.

Answer:

Step-by-step explanation:

Its not 56 feet, i got it wrong

The height of the basketball at 1 second will be 24 feet. Then the correct option is A.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

A basketball is shot into the air. Its height is represented by the polynomial equation which is given below.

h(t) = –16t² + 35t + 5

Where h is the height of the basketball at t seconds.

The height of the basketball at 1 second will be given as,

h(1) = –16 × (1)² + 35 × 1 + 5

h(1) = –16 + 35 + 5

h(1) = –16 + 40

h(1) = 24 feet

The height of the basketball at 1 second will be 24 feet. Then the correct option is A.

[tex]g(x)=f(-x)=\frac{3}{8}(4)^{-x}[/tex]

Step-by-step explanation:

The pre-image is

[tex]f(x)=\frac{3}{8}(4)^{x}[/tex]

To make a reflection across the y-axis, we need to apply the transformation

[tex](x,y) \implies (-x,y)[/tex]

Which give the function

[tex]g(x)=f(-x)=\frac{3}{8}(4)^{-x}[/tex]

Therefore, the right answer is the last choice.

Answer:

Option C is correct

Step-by-step explanation:

Given: inequality is [tex]50-3.50x>100-6x[/tex]

To find: situation that can be represented by the given inequality

Solution:

Cost of Dunkin Donuts gift card with Daniel = $50

Amount spent by Daniel per day = $3.50

Cost of Dunkin Donuts gift card with David = $100

Amount spent by David per day = $6

Amount left with Daniel after x days = [tex]\$(50-3.50x)[/tex]

Amount left with David after x days = [tex]\$(100-6x)[/tex]

According to question,

Amount left with Daniel after x days > Amount left with David after x days

[tex]50-3.50x>100-6x[/tex]

So, he inequality that satisfies the situation is [tex]50-3.50x>100-6x[/tex]

Step-by-step explanation:

Answer:

  $20

Step-by-step explanation:

Of the $100 John earned, $90 was for his hourly charge, which we assume is proportional to the area being mowed.

A lawn with 1/3 the circumference has (1/3)^2 = 1/9 the area, so presumably takes 1/9 of the time to mow. John's hourly charge for the smaller lawn will be $90/9 = $10. Added to his flat fee, he can expect to be paid $20.

_____

The ratio of areas of similar figures is the square of the ratio of any of the linear dimensions. All circles are similar. Circumference is measured in "units" and area is measured in "square units." So, circumference is a linear dimension (units to the first power).

Break it into 2 shapes :

1 = 7 x 14 = 98

2 = 5 x 5 = 25

Now add them together:

Total area = 98 + 25 = 123 square mm

Answer:

I think 8n >_ 60

Im not sure but thats what i put

Step-by-step explanation:

The inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

Inequality is an expression or statement of an order relationship, which involves the use of inequality signs, variables, numbers and/or algebraic expressions.

Thus:

n = number of brushes in a pack

The teacher must buy 60 brushes and above.

Thus:

8n ≥ 60 will represent the minimum number of brushes for the class.

Therefore, the inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

Answer: $6,000

Step-by-step explanation: If set up correctly, the value of the car at the end of 2006 times 0.6 (because the car is losing 0.4 of its value, so it keeps 0.6 of its value) should get you the value of the car at the end of 2007.

The equation should look like this:

(value of the car at the end of 2006) x 0.6 = (value of the car at the end of 2007)

Then you substitute: (value at the end of 2006) x 0.6 = 3600

Then divide: (value at the end of 2006) = 0.6 ÷ 3600

Then substitute again: (value at the end of 2006) = 6,000
