Completing the Square:

x^2 - 2x = 54

x^2 - 2x + 1 = 54 + 1

(x-1)^2 = 55

x - 1 = ±[tex]\sqrt{55\\}[/tex]

x = 1 ± [tex]\sqrt{55}[/tex]

Step-by-step explanation:

When you round you look at the number to the right of the number you're rounding. So you look at the 7. If it is larger than five (in this case it is) you round the number up.

10d + 5.50 = x (the total cost)

Answer:

4 minutes

Step-by-step explanation:

Miles to Minutes = 3:1

Miles to Minutes = 12:?

12/3=4

Miles to Minutes = 12:(1x4)

Miles to Minutes = 12:4

Miles = 12

Minutes = 4

Answer: 4 kilograms of bananas for $7.48

Step-by-step explanation:

Unit price for 1 kilo= $2.06

2.06 x 4 = 8.24

Unit price for 4 kilo= $1.87

2.06 > 1.87

So, 4 kilograms of bananas is the better buy.

Simple form:

Answer 1: 2.06

Answer 2: 1.87

Answer 3: greater than

Answer:

The probability that the height of a randomly selected tree is as tall as mine or shorter.

P(X≤182.2) = 0.0082

Step-by-step explanation:

Step(i):-

Mean of the Population = 191.8 ft

Standard deviation of the Population = 4 ft

Let 'X' be the random variable in normal distribution

X = 182.2 feet

[tex]Z = \frac{x-mean}{S.D}[/tex]

[tex]Z = \frac{182.2-191.8}{4} = -2.4[/tex]

Step(ii):-

The probability that the height of a randomly selected tree is as tall as mine or shorter.

P(X≤182.2) = P( z≤ -2.4)

                =  1-P(z>2.4)

                = 1-(0.5 + A(2.4))

              =  0.5 - A(2.4)

             = 0.5 - 0.4918

            = 0.0082

The probability that the height of a randomly selected tree is as tall as mine or shorter.

P(X≤182.2) = 0.0082

Answer:

A = 3.57 m²

Step-by-step explanation:

Given that,

The circumference of a circle is 7xm.

The expression for the circumference of a circle is given by :

[tex]C=2\pi r[/tex]

r is the radius of the circle

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{7}{2\times \dfrac{22}{7}}\\\\r=1.11\ m[/tex]

The area of a circle is given by :

[tex]A=\pi r^2\\\\A=3.14\times (1.11)^2\\\\A=3.89\ m^2[/tex]

Out of given option,

A = 3.57 m²

So, the area of the circle is 3.57 m².

Answer:

  40 : 110

Step-by-step explanation:

There are a number of ways you can go at this. One of my favorite is to consider the value of a "ratio unit." Here, a total of 4+11 = 15 "ratio units" represent the total to be divided: 150. So the value of each one is ...

  150/15 = 10

Then the division is ...

  4 : 11 = 10·4 : 10·11 = 40 : 110

_____

Alternate solution

Let x represent the larger share. Then the ratio is ...

  (150 -x) : x = 4 : 11

Cross-multiplying gives ...

  11(150 -x) = 4x

  1650 = 15x . . . . . add 11x, simplify

  110 = x . . . . . . . . . divide by 15; the larger share

  150-x = 150-110 = 40 . . . . . . the smaller share

The division is 40 : 110.

Answer:

Regan sold [tex]\mathbf{\frac{23}{12}}[/tex] gallons of lemonade

Step-by-step explanation:

Operations with Fractions

Mark sold [tex]2\frac{7}{8}[/tex] gallons of lemonade.

Regan sold [tex]\frac{2}{3}[/tex] as much lemonade as Mark

We can find the portion of lemonade Regan sold by multiplying both fractions. But first, we must convert to improper fraction:

[tex]2\frac{7}{8}=2+\frac{7}{8}=\frac{23}{8}[/tex]

Now we multiply:

[tex]\frac{23}{8}\cdot \frac{2}{3}=\frac{46}{24}=\frac{23}{12}[/tex]

Regan sold [tex]\mathbf{\frac{23}{12}}[/tex] gallons of lemonade
