A culture of bacteria living in a can doubles every minute. After 19 minutes the can is half- full. After how many minutes will the can be completely full?

Answer:

m∠7 = 64°

Step-by-step explanation:

∠7 and ∠8 are supplementary meaning they add up to 180°.

m∠7 + m∠8 = 180°

m∠7 + 116° = 180°

m∠7 = 64°

Answer:

180-116=64

Step-by-step explanation:

Angles sums should be 180 since it is straight angle

45 - [ 38 - { 60/3 - ( 6 - 3 )/3} ]

45 - [ 38 - { 60/3 - 3/3 } ]

45 - [ 38 - { 20 - 1 } ]

45 - [ 38 - 19 ]

45 - 19

Step-by-step explanation:

Answer:

3.75*A + 2.50*D = 35

A + D = 12

A = 12 - D

3.75*(12-D) +2.5*D= 35

45 - 3.75D + 2.5D = 35

45 - 1.25D = 35 |-35

10 = 1.25D | /1.25

8 = D

A+D=12

A+8=12 |-8

A=4

Answer:

The distance between the lines: 4x+3y-11 and 8x+6y=15 is​ [tex]\frac{7}{10}[/tex]

Step-by-step explanation:

You have two parallel and different lines. The form of the implicit equations is:

A*x + B*y + C= 0

A'*x + B'*y + C'=0

Since the two lines are parallel, the coefficients of their general equations must satisfy that the slopes are equal.

Therefore, the equations can be transformed so that the coefficients A and B are equal, multiplying or dividing one of them by a constant.

So, the distance between two lines can be expressed as follows:

[tex]d=\frac{|C-C'|}{\sqrt{A^{2} +B^{2} } }[/tex]

In this case, you have:

Then, you have:

Replacing in the definition of distance:

[tex]d=\frac{|-22-(-15)|}{\sqrt{8^{2} +6^{2} } }[/tex]

Solving:

[tex]d=\frac{|-7|}{\sqrt{8^{2} +6^{2} } }[/tex]

[tex]d=\frac{7}{\sqrt{8^{2} +6^{2} } }[/tex]

[tex]d=\frac{7}{\sqrt{64+36 } }[/tex]

[tex]d=\frac{7}{\sqrt{100 } }[/tex]

[tex]d=\frac{7}{10}[/tex]

The distance between the lines: 4x+3y-11 and 8x+6y=15 is​ [tex]\frac{7}{10}[/tex]

Answer:

x = 64

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

154 = x+90

Subtract 90 from each side

154-90 = x

64 =x

Answer:

x = 64

Step-by-step explanation:

First, we need to find the unknown interior angle next to the exterior angle.

? + 154 = 180

? = 26

Lastly, we need to find x.

x + 26 + 90 = 180

x + 116 = 180

x = 64

Answer:

a = 5

Step-by-step explanation:

According to the factor theorem, if x + 2 is a factor, then by dividing the polynomial by the binomial, we are meant not to have a remainder

In this case, the remainder would be zero

So, if we set the binomial equals zero and substitute the x-value into the polynomial, we are supposed to have 0

So we have this as;

x + 2 = 0

x = -2

-2^3 -2(-2)^2 -2(a) + 6 = 0

-8-8-2a + 6 = 0

-16 + 2a + 6 = 0

2a -10 = 0

2a = 10

a = 10/2

a = 5

Answer:

The greatest amount of Rainfall is 16 times the least amount of Rainfall.

Step-by-step explanation:

From the image, we can see the average monthly Rainfall and the frequency of each size in inches.

The largest is 2 inches while the smallest is ⅛ inches.

We are basically required to find the number that will be multiplied by the least amount of Rainfall to get the greatest amount.

Thus, we will just divide the greatest amount of Rainfall be the least.

This is; 2 ÷ ⅛ = 16

Answer:

16022 square foot

Step-by-step explanation:

The world's largest cookie was baked in North Carolina in 2003. Its diameter was 100 feet and it contained about 6,000 pounds of chocolate chips! If the cookie was a cylinder 1 foot tall, and you wanted to cover it with icing, how many square inches would you have to ice? Use 3.14 for .

We find the surface area of the cylinder

= 2πr(r + h)

r = Diameter /2 = 100 feet/2

r = 50 feet

h = 1 feet

Hence

2 × 3.14 × 50(50 + 1)

= 16022.122533 square foot

= 16022 square foot

      ✎Daily reminder: make sure to eat food and stay hydrated, have a good day :D

Answer:

y = 3x - 2.

Step-by-step explanation:

The slope of the line (m) = (10-4)/(4-2)

= 3.

y - y1 = m(x - x1)

y - 10 = 3(x - 4)

y = 3x - 12 + 10

y = 3x - 2.

Answer:

0.2805

Step-by-step explanation:

Given that p = 20% = 0.2, n = 300.

The mean (μ) = np = 0.2 * 300 = 60

The standard deviation (σ) = [tex]\sqrt{np(1-p)}=\sqrt{300*0.2(1-0.2)}=6.93[/tex]

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma }[/tex]

For x = 57:

[tex]z=\frac{57-60}{6.93 } =-0.43[/tex]

For x = 62:

[tex]z=\frac{62-60}{6.93 } =0.29[/tex]

From the normal distribution table, P(57 < x < 62) = P(-0.43 < z < 0.29) = P(z < 0.29) - P(z < -0.43) = 0.6141 - 0.3336 = 0.2805

✔ b = $1.14

the person above me doesn't make since so here the answers

Benjamin presently have $1.14.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Benjamin needs $0.75 more cents to buy a granola bar that costs $1.89.

let Benjamin have the amount $b.

So, the Expression to represent the situation is:

b + 0.75 = 1.89  

Now, subtract 0.75 from both side

b + 0.75 - 0.75 = 1.89 - 0.75

b = 1.14

Answer:

[tex]6[/tex]

The answer is C:6

Answer:

Vertex: [tex](x,y) = (4,4)[/tex], Axis of symmetry: [tex]x = 4[/tex], no x-Intercepts, y-Intercepts: [tex](x,y) = (0, 36)[/tex]. The graph is represented in the image attached below.

Step-by-step explanation:

The equation of the parabola in vertex form and whose axis of symmetry is vertical is described by this formula:

[tex]y - k = C\cdot (x-h)^{2}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]C[/tex] - Vertex constant.

[tex]h, k[/tex] - Coordinates of the vertex.

By direct comparison, we find the following information:

[tex]h = 4[/tex], [tex]k = 4[/tex], [tex]C = 2[/tex]

Vertex

The vertex is a point of the parabola so that [tex](x,y) = (h, k)[/tex].

If we know that [tex]h = 4[/tex] and [tex]k = 4[/tex], then the coordinates of the vertex are [tex](x,y) = (4,4)[/tex].

Axis of symmetry

The axis of symmetry is a line of the form [tex]x = h[/tex].

If we know that [tex]h = 4[/tex], then the axis of symmetry is [tex]x = 4[/tex].

To find the x and y intercepts, we need to transform the equation of the parabola into its standards, which is a second grade polynomial:

[tex]y - k = C\cdot (x-h)^{2}[/tex]

[tex]y - k = C\cdot (x^{2}-2\cdot h\cdot x +h^{2})[/tex]

[tex]y = C\cdot x^{2} -2\cdot C\cdot h \cdot x + (C\cdot h^{2}+k)[/tex]

If we know that [tex]h = 4[/tex], [tex]k = 4[/tex] and [tex]C = 2[/tex], then the equation of the parabola in standard form is:

[tex]y = 2\cdot x^{2}-16\cdot x + 36[/tex]

x-Intercepts

The x-intercepts of the polynomial (if exist) can be found by the Quadratic Formula:

[tex]x_{1,2} = \frac{16\pm \sqrt{(-16)^{2}-4\cdot 2\cdot (36)}}{4}[/tex]

[tex]x_{1,2} = 4 \pm \frac{\sqrt{-32}}{4}[/tex]

[tex]x_{1,2} = 4 \pm i \,\frac{4\sqrt{2}}{4}[/tex]

[tex]x_{1,2} = 4 \pm i\,\sqrt{2}[/tex]

As both roots are conjugated complex numbers, there are no x-intercepts.

y-Intercepts

The y-intercept (if exists) can be found by evaluating the polynomial at [tex]x = 0[/tex]:

[tex]y = 2\cdot 0^{2} - 16\cdot 0 + 36[/tex]

[tex]y = 36[/tex]

The y-intercept is [tex](x,y) = (0, 36)[/tex].

Lastly, we proceed to plot the function by using graphing tools.
