Answer:

1/6 is left

Step-by-step explanation:

A woman gives 1/4 of a cake to her son 1/4 to her daughter, and 1/3 to her husband. What fraction is left?

As 4*3=12, we need to convert into twelfths.

3/12 + 3/12 + 4/12 = 10/12. This needs to be subtracted from 1 (12/12).

12/12 - 10/12 = 2/12. Simplify to 1/6.

1/6 is left.

A table that represents a linear equation should be your answer. This means your slope should be constant/straight not like a parabola or absolute function.

Step-by-step explanation:

When you're trying to solve something using slope-intercept you can graph it or plug numbers for (x,y).  

Graph:

Start at (0,-3)

Then plot the point since that is your Y-Intercept

Then go 5 up and 4 over to find your next point.

Once done, you should connect the dots to form a slope or a linear equation.

Perpendicular formula

m1 * m2 = - 1

m1 = - 7

m2 = ??

Solution

-7 * m2 = -1

m2 = 1/7

y = 1/7 x + b

x = 8

y = -3                     Substitute these values into y = 1/7 x + b

-3 = (1/7)*8 + b    

-3 = 8/7 + b          Subtract 8/7  from both sides

-3 - 8/7 = b

-4 1/7 = b

Answer (perpendicular line) y = (1/7) x - 4 1/7  or

Answer (perpendicular line) y = (1/7) x - 4.14

Answer:

Green heart is 2 and blue shape is 8.

Step-by-step explanation:

We know 1 purple drop equals 3.

So 3+3 = 6

The total weight is 16 so we can do 16-6 = 10

We have 10 left. Since we need the weight to be balanced the green heart must be 2.

Because then it would be 8 on 1 side (2 purples equals 6 and 1 heart equals 2, so 6+2=8) and 8 on the other side (8+8=16).

Step-by-step explanation:

I think you made some mistakes in the problem definition.

I guess you mean

9 = (1/27)^(a+3)

let's think about how to create 9 out of 1/27 just by using exponents.

we note that 27 is 3³. and therefore the cubic root of 27 is 3.

so,

(1/27)^(1/3) = 1/3

because the exponent 1/3 means "cubic root". an exponent 1/2 means square root. and so on.

making the exponent negative means 1/...

so,

(1/27)^(-1/3) = 3

and now, with what exponent operation can we turn 3 into 9 ?

by squaring it.

so,

((1/27)^(-1/3))² = 9

putting an exponent on an exponent means to multiply the exponents during simplification.

therefore,

((1/27)^(-1/3))² = (1/27)^(-2/3) = 9

that means

a + 3 = -2/3

a = -2/3 - 3 = -2/3 - 9/3 = -11/3

so, the first answer option is correct.

The requried, factored form of the given expression is (x - 1)(x - 3)(x + 2).

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

To factor the polynomial f(x) = x³ – 2x² – 5x + 6 completely, we can use a combination of the rational root theorem and synthetic division.

We can use synthetic division to test each possible root and see if it is a factor of the polynomial. Starting with x = 2, we have:

2 | 1 -2 -5 6

  | 2 0 -10

  |_____________

1 0 -5 -4

Since the remainder is not zero, x = 2 is not a factor of the polynomial. Continuing with the other possible roots, we find that x = 1 and x = 3 are roots, but x = -1, x = -2, x = -3, and x = -6 are not roots.

Therefore, we can factor the polynomial as follows:

f(x) = x² – 2x² – 5x + 6

= (x - 1)(x - 3)(x + 2)

So the completely factored form of f(x) is f(x) = (x - 1)(x - 3)(x + 2).

Answer:

-4/5

Step-by-step explanation:

To find the slope of a line with two points, we do y2-y1/x2-x1.

y2 is 2. y1 is 6.

2-6 = -4

x2 is 8. x1 is 3

8-3 = 5

-4/5 is the answer meaning it is the slope.

Answer:

Slope of this line = -4/5.

Step-by-step explanation:

The formula is

Slope = (y2-y1)/(x2-x1)  where (x1, y1) and (x2, y2)  are  the 2 points.

So here we have:

(6-2)/(3-8)

= -4/5.

Step-by-step explanation:

Cylinder

Start by finding the volume of the cylinder as though the spheres were not there.

Volume of a cylinder = pi r^2 h

r = 6 inches

h = 25 inches.             Put the givens in the formula

Volume = pi 6^2 * 25

Volume = pi * 36 * 25

Volume = 900 pi

One sphere

Don't try and find the volume of both spheres. Just do one and double it.

V = pi * (4/3) * r^3

r = 6 inches

V = pi * (4/3) * 6^3

V = pi * 288 Cubic inches

Two spheres

Total volume spheres = 2 * 288 pi

Total Volume of spheres = 576 pi

Volume of the shaded region.

The following will act as a formula for the answer to the question

V_shade = Volume of the cylinder - volume of the 2 spheres

Substitute values into formula

Volume shade = 900 * pi - 576* pi       Take out common factor (pi)

Volume shade = pi  * (900 - 576 )

Volume of the shaded area

Volumne shade = pi *324

pi = 3.14

Volume shade = 1017.36

Answer:

volume of the shaded region = 1018

Applying the law of cosine, the largest angle in the given triangle, to the nearest whole degree, is: 99°.

Law of cosine is, c² = a² + b² - 2ab(cosC)

Let,

Plug in the values into the formula for the law of cosine:

26² = 15² + 19² - 2(15)(19)(cosC)

676 = 586 - 570(cosC)

676 - 586 = -570(cosC)

90 = -570(cosC)

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 16 - 1 = 15 df, is t = 1.7531.

Researching the problem on the internet, the standard deviation was of 42.1 mg/dL, hence the parameters are as follows:

[tex]\overline{x} = 264.7, s = 41.2, n = 16[/tex]

Thus, the bounds of the interval are given by:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 264.7 - 1.7531\frac{41.2}{\sqrt{16}} = 246.6[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 264.7 + 1.7531\frac{41.2}{\sqrt{16}} = 282.8[/tex]
