Answer:

a=223.57

c=181.43

Step-by-step explanation:

a=405-c

substitute for a in the equation :

12a+5c=3590

12(405-c)+5c=3590

4860-12c+5c=3590

-7c=3590-4860

-7c=-1270

c=1270/7=181.43

a=405-1270/7

a=1565/7=223.57

Answer:

28

Step-by-step explanation:

Simple solution:

Each one was 5 years younger 5 years ago, so subtract 5 from 38 for each one.

38 - 5 - 5 = 28

The sum of their ages was 28.

Algebra solution:

Kate is x years old now.

Gift is y years old now.

The sum of their ages now is x + y.

The sum of their ages is 38, so x + y = 38.

5 years ago:

Kate was x - 5 years old.

Gift was y - 5 years old.

The sum of their ages 5 years ago was x - 5 + y - 5 = x + y - 10.

Substitute 38 for x + y.

The sum of their ages was 38 - 10 = 28

The side of the edge of the cube is 9. 9cm

Given that the diagonal of a cube measures the square root of 294cm and the diagonal of a face measures 14cm

To find the edge of the face, we know that the face of the cube is a square

The table that has the y-value as 2 for each input

Step-by-step explanation:

The table that has the y-value as 2 for each input. This is because as x increases by 1, the y-value is increasing by 0, so the slope is 0/1 or 0. The vertical line doesn't have a zero slope, since it's undefined,  because if you take any two points the "run" is 0, thus you would be dividing by 0, the slope cannot be defined.

The regression equation is y = 3.231x + 10.138

The regression model that fits the data is a linear model.

This is so because as x increases by 1, the y value increases by an almost constant rate

To determine the regression equation, we make use of a graphing calculator

From the graphing calculator, we have the following summary:

The regression equation is then calculated as;

y = bx + a

Where

b = SP/SSX = 56.55/17.5 = 3.23143

a = MY - bMX = 18.22 - (3.23*2.5) = 10.1381

So, we have:

y = 3.23143x + 10.1381

Approximate

y = 3.231x + 10.138

Hence, the regression equation is y = 3.231x + 10.138

Answer:

x = -3

y = 9

Step-by-step explanation:

6x + 3y = 9 ⇒ ( 1 )

Divide the whole equation by 3.

2x + y = 3 ⇒ ( 2 )

-9x - 2y = 9 ⇒ ( 3 )

Let us take equation (2) and make y the subject of the equation.

2x + y = 3

y = 3 - 2x ⇒ ( 4 )

Now let us take equation (3) and find the value of x.

For that, we can replace y with ( 3 - 2x ).

Let us solve it now.

-9x - 2y = 9

-9x - 2 ( 3 - 2x ) = 9

-9x -6 + 4x = 9

-5x - 6 = 9

-5x = 9 + 6

-5x = 15

Divide both sides by (-5).

x = -3

And now let us take equation (4) to find the value of y.

For that, we can replace x with -3.

Let us solve it now.

y = 3 - 2x

y = 3 - 2 × -3

y = 3 + 6

y = 9

0.053 inches is 5.3x10-2 inches

Step-by-step explanation:

The goal is to convert he number into a format that has one digit to the left of the decimal point.  When moving the decimal point more to the left, each step reduces the number by a factor of 10/

742

74.2 is the original number reduced by 10.  To keep the number valid, we need to multiply by 10, which can be written as 74.2 x 10.

7.42 is reduced by another factor of 10:  7.42 x10x10  This is the same as 7.42x10^2

742 is 7.42x10^2

0.053

0.53 is the original number multiplied by 10.  To keep the number valid, we need to divide by 10, which can be written as 0.53x10^-1

5.3 is the original number divided by another factor of 10.  This can be written as 5.3x10^-2

0.053 inches is 5.3x10-2 inches

Step-by-step explanation:

If there are 4 people, and each person brings a gift for each of the other three people, that means that there are 12 gifts at the party. Let's say there are four people: A, B, C, and D. Person A would have to bring 3 gifts to give  B, C, and D. Similarly, B would bring a gift each for A, C, D. C would bring a gift for A, B, D. Lastly, D would bring a gift for A, B, and C. Each person brings three gifts to give to the other three people at the party, and 3*4 people is 12. I hope that makes sense.

The equations of the perpendicular lines are: y = 1/2x + 6, y = 15, y = -x - 2, y = 6x + 3 and y = 1/3x - 4

When a linear equation is represented as:

Ax + By = C

The slope (m) is:

m = -A/B

When the linear equation is represented as:

y = mx + c

The slope is m

A line perpendicular to a linear equation that has a slope of m would have a slope of -1/m

Using the above highlights, the equations of the lines are:

6. y = -2x + 5; (2, 7)

The slope is:

m = -2

The perpendicular slope is:

n = 1/2

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 1/2(x - 2) + 7

Evaluate

y = 1/2x - 1 + 7

This gives

y = 1/2x + 6

7. y = -5; (11, 15)

The slope is:

m = 0

The perpendicular slope is:

n = 1/0 = undefined

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 15

8. Graph ; (-12, 10)

The slope is:

m = (y2 - y1)/(x2 - x1)

Using the points on the graph, we have:

m = (2 - 3)/(3 - 4)

m = 1

The perpendicular slope is:

n = -1

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = -1(x + 12) + 10

y = -x - 12 + 10

Evaluate

y = -x - 2

9. y = -1/6x + 1; (-2, -9)

The slope is:

m = -1/6

The perpendicular slope is:

n = 6

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 6(x + 2) - 9

Evaluate

y = 6x + 12 - 9

This gives

y = 6x + 3

10. 6x + 2y = 14; (12, 0)

The slope is:

m = -6/2

m = -3

The perpendicular slope is:

n = 1/3

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 1/3(x - 12) + 0

Evaluate

y = 1/3x - 4

Hence, the equations of the perpendicular lines are: y = 1/2x + 6, y = 15, y = -x - 2, y = 6x + 3 and y = 1/3x - 4

the quadratic equation is:

y = 0.2*x*(x - 28)

If we know that the roots are J and K, and the leading coefficient is a, then the quadratic equation is:

y = a*(x - K)*(x - J)

Here we know that the roots are at x = 0 and x =28, then:

y = a*(x - 0)*(x - 28).

We also know that the vertex is a minimum, so a is positive, and we know that the vertex is (14, -40), then we have:

-40 = a*(14)*(14 - 24) = -a*196

a = 40/196 = 0.20

Answer:

∠ 3 = 105°

Step-by-step explanation:

∠ 3 and ∠ 6 are same- side interior angles and sum to 180° , that is

∠ 3 + ∠ 6 = 180°

∠ 3 + 75° = 180° ( subtract 75° from both sides )

∠ 3 = 105°

What the given proof is trying to show us is that; ∠3 = 126°

From the attached line, we see that angle 1 and angle 3 form a straight line. Now, since we know that angles on a straight line sum up to 180°, then it means that they are supplementary.

We are given;

1) ∠1 and ∠2 are supplementary

2) ∠1 = 36°

Thus from definition of complementary angles, we can say that;

36° + ∠2 = 90°

Subtraction property of equality when applied gives;

∠2 = 54°

We are told that ∠2 and ∠3 are linear pairs and as such;

∠2 + ∠3 = 180° from linear pairs theorem.

By substitution property of equality we have;

54° + ∠3 = 180°

Solving gives ∠3 = 126°

Answer:

Step-by-step explanation:

The roots of a polynomial function tells us about the position of the equation on a graph and the roots also tells us about the complex and imaginary roots. So, Roots of chords are similar to the roots of polynomial functions.

A real root of a polynomial function is the point where the graph crosses the x-axis (also known as a zero or solution). For example, the root of y=x^2 is at x=0.

Roots can also be complex in the form a + bi (where a and b are real numbers and i is the square root of -1) and not cross the x-axis. Imaginary roots of a quadratic function can be found using the quadratic formula.

A root can tell you multiply things about a graph. For example, if a root is (3,0), then the graph crosses the x-axis at x=3. The complex conjugate root theorem states that if there is one complex root a + bi, then a - bi is also a complex root of the polynomial. So if you are given a quadratic function (must have 2 roots), and one of them is given as complex, then you know the other is also complex and therefore the graph does not cross the x-axis.

So, The roots of a polynomial function tells us about the position of the equation on a graph and the roots also tells us about the complex and imaginary roots. So, Roots of chords are similar to the roots of polynomial functions.

4.59 g will be the amount of substance that will be present after 5 year.

Given: 16g of radioactive substance

            8g left after 8 year

Concept: In a chemical reaction, the half-life of a species is the time it takes for the concentration of that substance to drop to half its original value. In a first-order reaction, the half-life of the reactant is ln(2)/λ, where λ (also referred to as k) is the reaction rate constant.

The half-life is given as 5 years, so the amount remaining after 9 years will be found by using the steps done below:

Remaining amount of radioactive substance = initial × (1/2)^(t/(half-life))

Remaining substance = (16 g)×(1/2)^(9/5) ≈ 4.59 g

After 9 years i.e., after 8 years have passed

About 4.59 g of the substance remains.
