Step-by-step explanation:

Answer:

x = 6

Step-by-step explanation:

2x - 5 = 7

Add 5 on both sides.

2x - 5 + 5 = 7 + 5

2x = 12

Divide both sides by 2.

2x/2 = 12/2

x = 6

Answer:

The answer is option D.

Step-by-step explanation:

Because -3/-5 = 3/5 since the negative sign cancel each other.

Hope this helps you

Answer:

The fourth  option

Step-by-step explanation:

-3/5 is the same as - 3/5 or 3/-5 (it doesn't matter where the negative sign goes-on the side, numerator, or denominator)

-(-3/-5) is basically negative of -3/-5

-3/-5 is the not the same as -3/5

Answer:

1. 3511

2 B= 0.25

Step-by-step explanation:

1. The number of single scoop cone is represented as s while the number of double scoop cone is represented as d. The total number of scoop cone the coach bought is 15 and the total sum is 57 dollars .

Therefore, multiply the number of single scoop cone(s) by each price and also find the product of the number of double cone(d) and the price of each . Then add the result to get 57 dollars. Therefore, A = 3 dollars and B = 5 dollars. The sum of s and d will give 15 . Therefore, C and E is equals to 1.

2. s is the number of small candies while l is the number of big candies. The individual cost of the small candies and the large candies are in cents so we have to convert them to dollars.

Cost of each small candies = 10/100 = 0.1 dollars

Cost of each large candies = 25/100 = 0.25 dollars.

Therefore, using the same principle as number 1

A = 0.1 dollars

B = 0.25 dollars

The value of E = 52

3. IMS (Infinitely Many Solutions)

Step-by-step explanation:

First graph has parallel lines, which means the lines will never intersect, therefore it will be impossible to get a solution.

Second Graph has 2 lines that intersect at points (0,3) which will give only one solution.

Third Graph has 1 line that overlaps at every point, which means that any point which is on the that line is a solution.

Answer:

(2, 0)

Step-by-step explanation:

y = x - 2

y = x² - 3x + 2

Since both equations equal y, you can set the equations equal to each other.

x - 2 = x² - 3x + 2

x = x² - 3x + 4

0 = x² - 4x + 4

0 = (x - 2)(x - 2)

x - 2 = 0

x = 2

Now that you have an x-value, solve for y.

y = x - 2

y = 2 - 2

y = 0

The solution is (2, 0).

Step-by-step explanation:

Plug in each value of x into the equation and find y:

Answer:

volume of the sphere

=4/3π × r³

=4/3π × 3 × 3 × 3

=4/3π × 27

=36π ( c )

The value of volume of the sphere shown with a radius of 3 is,

⇒ 36π units³

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Since, We know that;

volume of the sphere is,

V = 4/3π × r³

Here, We have;

r = 3

Hence, We get;

V = 4/3π × 3 × 3 × 3

= 4/3π × 27

=36π

Thus, The value of volume of the sphere shown with a radius of 3 is,

⇒ 36π units³

Answer:

The yearly growth percentage is 5%

The worth of the company in 2010 is 433 million of dollars approximately

Step-by-step explanation:

The annual growth percentage;

We can write the equation of w as follows;

W = 266 (1 + 0.05)^t

Compare this with ;

W = I(1 + r)^t

Where W is the worth at a particular year

I is the initial worth at year 2000

r is the rate of increase per year

and t is the time since 2010

where it is the 0.05 that represents the yearly growth percentage (r)

0.05 as a percentage is 5/100 which is 5%

Now, we want to calculate the worth of the company in the year 2010

The first thing to do here is to calculate the value of t.

The value of t is the difference between the years 2000 and 2010 and that is 2010-2000 = 10 years

Now to find the worth at 2010, simply substitute that value of t = 10 in the equation

Thus;

W = 266(1.05)^10

W = 433.2859707228

Which is approximately 433

Let s represent the speed of the bus.

From the information given, the bus needs to cover a distance of 240 km in less than 5 hours. The formula for calculating the speed of the bus, s is expressed as

Speed, s = distance covered by the bus/ time taken to cover the distance

Therefore,

Speed, s = 240/5 = 48 km/hr

A higher speed would ensure the bus covers the distance in less than 5 hours. Therefore, the inequality that represents the speed (s) of the bus would be

s ≥ 48

Answer:

Step-by-step explanation:

The constant term of x^2 + 13x – 48 factors into either (3)(-16) or (-3)(16).

Note how 16 - 3 = 13, which is the coefficient of the middle term.  Thus, the factors are

(x + 16)(x - 3) which is equivalent to x^2 + 16x - 3x - 48, or x^2 + 13x - 48.

The factored form of the given polynomial  is (x - 3)(x + 6)

Since the equation is [tex]x^2 + 13x - 48[/tex]

Now

The four-term polynomial is

[tex]x^2 + 16x - 3x - 48[/tex]

x(x + 16) - 3(x + 16)

(x - 3)(x + 6)

Here polynomial represents the expression that includes the additions, subtraction, etc

Therefore, The factored form of the given polynomial  is (x - 3)(x + 6)

Answer:

The constant term is 240. It represents the initial daily revenue.

Step-by-step explanation:

It is given that Tico's Taco Truck is trying to determine the best price at which to sell tacos, the only item on the menu,  to maximize profits.

The owner can calculate the daily revenue using the polynomial  expression

where x is the number of $1 increases in the taco price.

Constant term does not contain any variable.

In the given expression 240 is free from variable x. So, the constant term is 240.

The value of expression is 240 for x=0. Since x is the number of $1 increases in the taco price, therefore 240 is the daily revenue when the taco price is not increased or the taco price increased by 0.

Therefore the constant term is 240 and it represents the initial daily revenue.

Step-by-step explanation:

BD is 32 units.

BE is half of BD

Answer:

[tex]y=\frac{5}{6}x+5[/tex]

Step-by-step explanation:

Well this is actually really simple we just have to look at the line and see what attributes it has so we can make an equation.

So slope intercept form is [tex]y=mx+b[/tex].

Like to find the y intercept we know it is the point that the line touches the y axis which is 5.

Now for the slope, the slope is how far each points are from each other on a line so to find the slope we can use the following formula [tex]\frac{y^2-y^1}{x^2-x^1}[/tex].

So to do this we need two points that are on the line we can use (-6,0) and (6,10).

So y2 is 10 and y1 is 0 so 10-0 is 10 and 6 - -6 is 12 so the slope is 10/12 and we have to simplify it to 5/6 so the slope is 5/6 and now we have to put it in slope intercept -> [tex]y=\frac{5}{6}x+5[/tex]

Given that:

Mean (μ) = 1.93, standard deviation (σ) = 1.08 pounds, sample (n) = 62.

the mean weight of discarded plastic for all household is given by:

[tex]\mu_x=\mu = 1.93\ pounds[/tex]

The standard deviation of discarded plastic for all household is given by:

[tex]\sigma_x=\frac{\sigma}{\sqrt{n} } =\frac{1.08}{\sqrt{62} }=0.137\ pounds[/tex]

The confidence (c) = 90% = 0.9

α = 1 - c = 1 - 0.9 = 0.1

α/2= 0.1/2 = 0.05

The z score of 0.05 corresponds to the z score of 0.45 (0.5 - 0.05) which is 1.645. i.e. [tex]z_\frac{\alpha}{2}=z_{0.05}=1.645[/tex]

The margin of error (E) = [tex]z_{0.05}\frac{\sigma}{\sqrt{n} }=1.645*\frac{1.03}{\sqrt{62} }= 0.2256[/tex]

Lets take a look at the sequence!

It starts with 3 and then goes to 7. Which means it is adding 4 each time it continues. To confirm this, lets look at 11. 7 goes to 11, which again means it is adding 4! So we understand and now the pattern!

Rather than doing a buttload of work, lets do it an easier way. Lets plug 18 into a  calculator!

Answer:

380 square inches

Step-by-step explanation:

We are given the measurements of the Rectangular Prism as

8 inches by 9 inches by 10 inches

Where based on the order of arrangement:

8 inches = Length

9 inches= Width

10 inches = Height

Step 1

Find the amount of wrapping paper needed

Perimeter = 2L + 2W

= 2 × 8 + 2 ×9

= 16 + 18

= 34 inches

Base = L × W

= 8 × 9

= 72 inches

Surface Area of the Rectangular Prism =PH + 2B

Where P = Perimeter

H = Height

B = Base

= 34 × 10 + 2× 72

= 340 + 144

= 484 square inches

The area of the Rectangular prism = 484 square inches

Step 2

So we were told that she used wrapping paper the measured 2 feet by 3 feet.

We would convert the values in feet to inches

1 ft = 12 inches

Length = 2 ft = 2 × 12 = 24 inches

Width = 3 ft = 3 × 12 = 36 inches

We find the area of the wrapping paper

Length × Width = 24inches × 36 inches = 864 square inches.

Step 3

The amount of square inches of wrapping paper left over is calculated as:

Area of the wrapping paper used - Area of the Rectangular prism

= 864 square inches - 484 square inches

= 380 square inches.

Therefore, the amount of square inches of wrapping paper left over is 380 square inches.
