Answer:

50

Step-by-step explanation:

415 is closer to 400, so just divide that by 8 to get 50.

Answer: (-260, -13)

Step-by-step explanation:

To find the midpoint  of  a line we find the average of x coordinates and the average of the y coordinates.So since two  of the endpoint is already given we could find the midpoint  by setting and equation up.

[tex]\frac{-x+(-4)}{2} = -132 x= -260[/tex]  

The same way for the  y coordinates

[tex]\frac{y+(1)}{2} = -6[/tex]     y = -13

Answer:

Just multiply the absolute values and make the answer positive. When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative. When you divide two integers with the same sign, the result is always positive.

Answer:

  $31.62

Step-by-step explanation:

Assuming the price is proportional to the volume, your price will be ...

  price/(10.83 gal) = ($10.16)/(3.48 gal)

  price = $10.16(10.83/3.48) ≈ $31.62

You will have to pay $31.62.

Answer:

16x-19

Step-by-step explanation:

Step-by-step explanation:

Hey, there!

While simplifying the algebraic expression you must remember: multiply or take LCM first and then add or or subtract like terms then if there is division then you may cut like terms of numerator and denominator.

Here,

[tex] - 2(x - 1) + 3(6x - 7)[/tex]

Is given.

Multiply (x,-1) by -2 and (6x,-7) by 3.

[tex] (- 2x + 2) + (18x - 21)[/tex]

open brackets.

[tex] = - 2x + 2 + 18x - 21[/tex]

Add and subtract like terms.

[tex] = - 2x + 18x + 2 - 21[/tex]

[tex] = 16x - 19[/tex]

Therefore, the answer is (16x - 19).

Hope it helps.....

Answer:

A) 44.26

B) 9.43

C) (2.5,3.5)

D) OH

E) 26.26

Step-by-step explanation:

Let’s figure out the lengths first.  Three are straight line, so are easy:

HE=9, SE=11, SU=9

The other two, you need to use the distance formula or Pythagorean Theorem. OH=8²+5²=c² = 64+25=c² = 89=c² = √89 = 9.43

OU=3²+5²=c² = 9+25=c² = 34=c² = √34 = 5.83

Now we can start answering the questions.

A) 9+11+9+9.43+5.83=44.26

B) 9.43

C) You already have: (2.5,3.5)

D) OH=9.43.  EH=9.  OH is longer.

E) HU is 11. OH is 9.43.  OU is 5.83.  11+9.43+5.83=26.26

Answer:

K = [tex]\frac{4r}{n} -a[/tex] n [tex]\neq 0[/tex]

Step-by-step explanation:

We have our equation [tex]r = \frac{n}{4} (a+K)[/tex] and are looking for K

First we have to switch sides :

[tex]\frac{n}{4} (a+K) = r[/tex]

Since we have a denominator of 4, we multiply both sides by 4 :

[tex]n (a+K) = 4r[/tex]

We then divide both sides by n :

[tex]a+K = \frac{4r}{n} ; n\neq 0[/tex]

Subtract a from both sides :

[tex]K = \frac{4r}{n} -a; n\neq 0[/tex]

Answer:

They are not similar.

Step-by-step explanation:

QP would be equal to FP if they were equal but they aren't equal so....yeah

4 people x 10 minutes each = 40 minutes per day.

5 gallons per minute x 40 minutes = 200 gallons per day.

200 gallons per day x 365 days per year = 73,000 gallons a year.

Solution

Provided :-

• I have $138

• I save $12 per week

• Friend have $ 98

• He saves $17 per week

Let the number of weeks required to have same balance be x

→ 138 + 12x = 98 + 17x

→ 138 - 98 = 17x - 12x

→ 40 = 5x

→ x = 8

So we need 8 weeks

Answer: 8 weeks

Step-by-step explanation:

Let x = the number of weeks

138+12x=98+17x

 40+12x=17x

        40=5x

          x=8

Hope this helps!! :)

Please let me know if you have any question

Answer:

41

Step-by-step explanation:

when there is midpoint it bisects the segment(cuts it in equal halfs)

3x+5 = 5x-19

3x + 24 = 5x

24 = 2x

12 = x

3(12) + 5 =

36 + 5

41

Answer:

The value of segment DF is 41 units.

Step-by-step explanation:

If we know that F is the midpoint of DE, we can conclude that DF and FE have the same value.  This lets us set up the following equation:

DF = FE, which when we substitute in our given values is:

3x + 5 = 5x - 19

The next step is to solve this equation.  We should start by subtracting 3x from both sides of the equation.

5 = 2x - 19

Then, we can add 19 to both sides of the equation.

24 = 2x

Finally, we can divide both sides by 2.

x = 12

Now that we have a value for x, we need to find the length of DF.  To do this, we can just plug in our value for x into the given expression for DF and simplify.

DF = 3x + 5 = 3(12) + 5 = 36 + 5 = 41

Therefore, the correct answer is 41.

Hope this helps!

Answer: 3 gallons

Step-by-step explanation:

From the question, we are informed that Connor is driving on a long road trip and currently has 9 gallons of gas in his car. We are also told that for every hour that he drives, his car uses up 2 gallons of gas.

After driving for 3 hours, his car would have used:

= 3 × 2 gallons

= 6 gallons of gas

Amount of gas left will be:

= 9 gallons - 6 gallons

= 3 gallons

Answer:

A. Real number

Step-by-step explanation:

Fact :Real numbers that include decimal points are known as floating point numbers because the decimal floats within the numbers.

The number 37.9 is a real number which is the correct option (A).

Real numbers are defined as the value of a continuous quantity that can represent a distance along a line a real number in mathematics. Rational and irrational numbers are both real numbers. Rational numbers such as integers (-7, 0, 4), fractions(5/2,7/2, 4.2), and irrational numbers such as √5, π, etc., are all real numbers.

A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, and b are real numbers and i is an imaginary number.

Given that number is 37.9

Due to the fact that decimal places can move about within real numbers containing decimal points, these numbers are referred to as floating point numbers.

Hence, the number 37.9 is a real number.

Answer: The SSS postulate would be those three letters.

Step-by-step explanation:

Here's how I got my answer:

Since you know that two pairs of sides are congruent and that the two triangles lie on the same side, then you can conclude that all three pairs of sides are congruent. Therefore, use the SSS postulate (Side-Side-Side) as the proof that the two triangles are congruent.

Greetings from Brasil...

For reverse function, just invert the X by the Y and vice versa.

Note that F(X) = Y and F⁻¹(X) = Y⁻¹

F(X) = 1(9X - 2)  ⇔  Y = 1(9X - 2)

replacing X with Y⁻¹

X = 1(9Y⁻¹ - 2)

Depends on your level of skills for one. Let's say you can replace a tire on a car within 30 min to 1 hr from the time you open the trunk to get the replacement.
