PB is a line segment on a number line. It has endpoints at -2 and 12. What is the coordinate of its midpoint?

Answers

Answer 1
well, first find the distance between the two numbers.
This can be done by adding the absolute values.

|12| + |-2| = 14.

mid = half

so what is half of 14? 7 is half of 14.

So, it is 7 less than the last point and 7 more than the first

-2 + 7 = 5
12 - 7 = 5

so, the midpoint is 5.
Hope this helps!

There are two positive numbers. four times the small number plus 3 times the big number is 41. two times the small number plus the big number is 15. what is 10 times the big number minus 6 times the small number;

Answers

the small number is 2 the large number is 11.
4(2)+11(3)=41
2(2)+11=15
11(10) -2(6) = 98


hope that helps

Final answer:

To find the value of 10 times the big number minus 6 times the small number, we need to solve a system of equations. The solution to the system is x = 2 and y = 11, so the value of 10y - 6x is 98.

Explanation:

To find the value of 10 times the big number minus 6 times the small number, we need to solve the system of equations:

4x + 3y = 41 (equation 1)

2x + y = 15 (equation 2)

We can first solve equation 2 for y by subtracting 2x from both sides: y = 15 - 2x. Now we can substitute this value of y into equation 1:

4x + 3(15 - 2x) = 41

Simplifying, we get: 4x + 45 - 6x = 41

Combining like terms, we have: -2x + 45 = 41

Subtracting 45 from both sides, we get: -2x = -4

Dividing both sides by -2, we get: x = 2

Now we can substitute this value of x back into equation 2 to solve for y:

2(2) + y = 15

Simplifying, we get: 4 + y = 15

Subtracting 4 from both sides, we get: y = 11

Finally, we can calculate 10 times the big number minus 6 times the small number:

10y - 6x = 10(11) - 6(2) = 110 - 12 = 98

The concession stand at a sports arena sells large 3-pints sodas. on an average night four sodas are sold each minute. how many gallons of soda are sold per hour?

Answers

The first thing you must know to answer this is that 1 pint = .125 gallons. That means that each 3 pints drink sold is .375 gallons (.125*3=.375). Now, the stand sells 4 of these .375 gallon drinks a minute. Therefore they would sell 240 of these an hour, since there are 60 minutes in an hour. You can calculated this using this equation [(4 drinks/1min)*(60min/1hour)]. Now we can multiply the number of drinks sold in an hour by the amount of soda in each drink to get the total gallons sold per hour. The equation for this is 240*.375. This equals 90. Therefore the answer is 90 gallons per hour.

if two angles of one polygon are equal to two angles of a second polygon then the two polygons are similar

To answer your question, the best answer would be B. I hope this helps you out :)

From,
Sal Vulcano

Final answer:

The statement is B. sometimes true. Two polygons are similar if their corresponding angles are equal and their corresponding sides are in proportion. However, it is possible for two polygons to have equal angles and not be similar if their sides are not in proportion.

Explanation:

The statement that if two angles of one polygon are equal to two angles of a second polygon then the two polygons are similar is sometimes true.

Two polygons are similar if their corresponding angles are equal and their corresponding sides are in proportion. Therefore, if two angles of one polygon are equal to two angles of a second polygon, it is possible that the polygons are similar, but it is not always the case.

For example, consider two rectangles. Both rectangles have two pairs of equal angles, but they may not be similar if their sides are not in proportion.

Write y = 3x^2-12x+11 in vertex form. I know the answer, just dont know how to show the work.

Answers

I'll write it out instead of typing it.  I think it would be easier to read.

The equation in vertex form is given as:

y = a (x - h) ² + k where a, h, and k are constant.

The equation y = 3x² - 12x + 11 in vertex form is  y = 3(x - 2)² + 7.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation in vertex form is given as:

y = a (x - h) ² + k where a, h, and k are constant.

We have,

y = 3x² - 12x + 11

3x² - 12x can be written as:

Taking out common value.

3(x² - 4x).

Now,

y = 3(x² - 4x)  + 11 _____(A)

x² - 4x can be written as:

Squaring we get,

= x² - 2.2x + 2² - 2²

= (x² - 2.2x + 4) - 4

[ (a - b)² = a² - 2ab + b ]

= (x - 2)² - 4 ________(B)

Now,

From (A) and (B) we get,

y = 3 (x - 2)² - 4 + 11

y = 3(x - 2)² + 7

Thus,

The equation y = 3x² - 12x + 11 in vertex form is  y = 3(x - 2)² + 7.

A square scarf is folded in half to form a rectangle. if the resulting rectangle has a perimeter of 15 inches, what are the area and perimeter of the square scarf?

Answers

Let x =  the length of each side of the square.

Therefore the dimensions of the rectangle are x and x/2.
Because the perimeter of the rectangle is 15 inches, therefore
2x + 2(x/2) = 15
2x + x = 15
3x = 15
x = 5 in.

The perimeter of the square scarf is 4x = 4*3 = 12 in.
The area of the scarf is 3*3 = 9 in²

Answer:
Perimeter = 12 in
Area = 9 in²

Attached the solution. It is important to know the 30-60-90 and 45-45-90 special right triangles.

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

We have been given an image of two right triangles and we asked to find the value of x.

First of all , we will find the length of segment RT using sine.

[tex]\text{Sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}[/tex]

Upon substituting our given values in above formula we will get,

[tex]\text{Sin}(60^{\circ})=\frac{2\sqrt{3}}{RT}[/tex]

[tex]RT=\frac{2\sqrt{3}}{\text{Sin}(60^{\circ})}[/tex]

[tex]RT=\frac{2\sqrt{3}}{\frac{\sqrt{3}}{2}}[/tex]

[tex]RT=\frac{2\sqrt{3}}{\sqrt{3}}\times 2[/tex]

[tex]RT=2\times 2[/tex]

[tex]RT=4[/tex]

Now we know that length of segment RT and angle QRT of triangle QRT, so we will use tangent to find the length of segment QR (x) as:

[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]

[tex]\text{tan}(45^{\circ})=\frac{x}{4}[/tex]

Multiplying both sides of our equation by 4 we will get,

[tex]\text{tan}(45^{\circ})*4=\frac{x}{4}*4[/tex]

[tex]\text{tan}(45^{\circ})*4=x[/tex]

Substituting [tex]\text{tan}(45^{\circ})=1[/tex] we will get,

[tex]1*4=x[/tex]

[tex]4=x[/tex]

Therefore, the value of x is 4 units.

A.$165.99
B.$170.10
C.$165.51
D.$174.90

HELPPPPPP ME

Answers

Answer:

Option B. $170.10

Step-by-step explanation:

Gail bought groceries worth = $165.00

She gets rebate of taxes on the amount = $80.00

She has to pay tax on = 165 - 80 = $85.00

In her state sales tax are = 6%

So her tax on groceries  = 6% of 85 = 0.06 × 85 = $5.10

Now she paid total amount = 165 + 5.10 = $170.10

Gail paid $170.10 for the groceries, including sale tax

Option B. $170.10

Scott earns 16.85 per hour at his job. He works 7 hour per day , 4 days per week. What Scott's gross income in 4 weeks

Answers

Scott's gross income in 4 weeks, rounded to the nearest cent, is $1887.20.

Calculate Scott's daily earnings:

  Scott earns $16.85 per hour, and he works for 7 hours per day.

  Daily earnings = $16.85/hour × 7 hours = $117.95

Calculate Scott's weekly earnings:

  Scott works 4 days per week.

  Weekly earnings = Daily earnings × Number of days worked per week

                  = $117.95/day × 4 days/week

                  = $471.80

Calculate Scott's gross income for 4 weeks:

  Scott works for 4 weeks.

  Gross income for 4 weeks = Weekly earnings × Number of weeks

                            = $471.80/week × 4 weeks

                            = $1887.20

However, we need to ensure the precision of the final answer. As currency involves cents, it's important to round appropriately.

Since we're dealing with money, we'll round to the nearest cent.

After rounding, the gross income for 4 weeks is $1887.20.

What value of c makes x2 − 12x + c a perfect square trinomial? −36 −24 24 36

Answers

Take half of the middle coefficient.
Then square it.

-12/2 = -6

(-6)^2 = 36

c = 36

Answer: The value of c must be 36 to make it perfect square trinomial.

Explanation:

A standard perfect square trinomial is [tex]x^2+2ax+a^2=(x+a)^2[/tex] where [tex]a^2[/tex] is the constant term.

Given trinomial [tex]x^2-12x+c=x^2+2(-6)a+c[/tex]

On comparing with standard perfect square trinomial we get a=-6

Therefore the constant term c=[tex]a^2=(-6)^2=36[/tex]

Such that the trinomial becomes [tex]x^2-12x+36=x^2+2(-6)x+(-6)^2=(x-6)^2[/tex] a perfect square trinomial.

Hence the value of c for the given trinomial must be 36 to make it perfect square trinomial.
