Find the greatest common factor of 28 and 63

Answer:

1.6 x 10^4

Step-by-step explanation:

First, 8*2 = 16

Since we are using scientific notation, this is expressed as 1.6 * 10^1

When we multiply using scientific notation, we add the exponents, therefore, 10^-2 x 10^5 = 10^3

1.6 x 10^1  x 10^3

We get 1.6 x10^4

Answer:

  8m³ -4m² +3m

Step-by-step explanation:

The perimeter of a triangle is the sum of the lengths of its three sides. Here, you're given the perimeter and two of the sides. The third side will be the length that makes up the difference.

  P = side 1 + side 2 + side 3

  18m³ +2m² -m = (5m³ +3m² -2m) +(5m³ +3m² -2m) + side 3

  18m³ +2m² -m = (10m³ +6m² -4m) + side 3 . . . . . collect terms

  18m³ +2m² -m - (10m³ +6m² -4m) = side 3 . . . . . subtract (10m³ +6m² -4m)

  m³(18 -10) +m²(2 -6) +m(-1 +4) = side 3 . . . . . . . . . group like terms

  8m³ -4m² +3m = side 3

Answer:

1/2 = 1

3/4 = 1.5

0.875 = 1 3/4

1 = 2

1.25 = 2 1/2

Step-by-step explanation:

The solution is

Cups of sugar = 1/2 cups , Cups of flour = 1 cup

Cups of sugar = 3/4 cups , Cups of flour = 1 1/2 cups

Cups of sugar = 7/8 cups , Cups of flour = 1 3/4 cups

Cups of sugar = 1 cup , Cups of flour = 2 cups

Cups of sugar = 5/4 cups , Cups of flour = 2 1/2 cups

What is an Equation?

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.

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 data ,

Let the number of cups of sugar = S

Let the number of cups of flour = F

Now , the equation will be

1/2 cups of sugar will result in = 1 cup of flour

So , the ratio of S : F = 1 : 2

Now ,

3/4 cups of sugar will result in = 2 x 3/4 cups of flour

3/4 cups of sugar will result in = 6/4 cups of flour

3/4 cups of sugar will result in = 3/2 cups of flour

Now ,

S cups of sugar will result in = 1 3/4 cups of flour

S cups of sugar will result in = 7/4 cups of flour

S cups of sugar = ( 1/2 ) ( 7/4 ) cups

S cups of sugar = 7/8 cups

7/8 cups of sugar = 1 3/4 cups of flour

Now ,

1 cup of sugar = 2 x 1 cups of flour

1 cup of sugar will result in = 2 cups of flour

Now ,

S cups of sugar will result in = 2 1/2 cups of flour

S cups of sugar = 5/2 cups of flour

S cups of sugar = ( 1/2 ) x ( 5/2 ) cups

S cups of sugar = 5/4 cups

5/4 cups of sugar = 2 1/2 cups of flour

Hence ,

Cups of sugar = 1/2 cups , Cups of flour = 1 cup

Cups of sugar = 3/4 cups , Cups of flour = 1 1/2 cups

Cups of sugar = 7/8 cups , Cups of flour = 1 3/4 cups

Cups of sugar = 1 cup , Cups of flour = 2 cups

Cups of sugar = 5/4 cups , Cups of flour = 2 1/2 cups

Given:

[tex]\dfrac{5}{6+2i}[/tex]

To find:

The  quotient in the form a + bi.

Solution:

We have,

[tex]\dfrac{5}{6+2i}[/tex]

Multiply numerator and denominator by 6-2i.

[tex]=\dfrac{5\times (6-2i)}{(6+2i)\times (6-2i)}[/tex]

[tex]=\dfrac{5(6)+5(-2i)}{6^2+(2i)^2}[/tex]

[tex]=\dfrac{30-10i}{36+4i^2}[/tex]

[tex]=\dfrac{30-10i}{36+4(-1)}[/tex]    [tex][\because i^2=-1][/tex]

On further simplification, we get

[tex]=\dfrac{30-10i}{36-4}[/tex]

[tex]=\dfrac{30-10i}{32}[/tex]

[tex]=\dfrac{30}{32}-\dfrac{10i}{32}[/tex]

[tex]=\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex]

Answer:

The growth rate is 0.6

The growth factor is 1.6

Step-by-step explanation:

Generally, the exponential equation can be written as;

y = a(1 + r)^x

Where a is the initial value of 100

r is the growth rate

So let us form equations;

160 = 100(1 + r)^1 •••••(i)

Also;

256 = 100(1 + r)^2 •••••••(ii)

Divide equation ii by i

256/160 = 1 + r

1.6 = 1 + r

r = 1.6-1

r = 0.6

The answer for this question is 72.25pi

The area of the circle is 72.25π ft².

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.

As per the given data:

circumference of a circle = 17π ft

To find the area of the square:

Area = πR²

For radius (R):

2πR = 17π

R = (17/2) ft

Area = π(17/2)²

= 72.25π ft²

Hence, the area of the circle is 72.25π ft².

The measure of the angle m∠J is  35°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located.

Consider the triangle KJL,

The line KM is perpendicular to the line JL and M is the midpoint of the line JL.

Therefore, the angle KMJ will be equal to 90°.

Now, we have the angle KJM is equal to 55°.

We know the sum of all interior angles of a triangle is 180°.

So,

In triangle JKM,

∠JKM + ∠KJM + ∠KMJ = 180°

∠JKM + 55° + 90° = 180°

Subtracting 90° from each side of the equation.

∠JKM + 55° + 90° - 90° = 180° - 90°

∠JKM + 55° = 90°

Subtracting 55° from each side of the equation.

∠JKM + 55° - 55° = 90° - 55°

∠JKM = 35°

Answer:

$17.60

Step-by-step explanation:

Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound

1 pounds = $5

2 1/4 pounds = x

x = 2 1/4 × $5

x = 9/4 × $5

x = $45/4

x = $11.25

9 pounds of pears at $2.35 per pound.

1 pound = $2.35

9 pounds = x

x = 9 × $2.35

x = $21.15

Total amount that she spent =

$11.25 + $21.15

= $32.40

If she paid with a $50 bill, how much change did she receive?

The change she received =

$50 - $32.40

Answer:  second and fourth choices have infinitely many solutions

Step-by-step explanation:

When you combine the like terms in those two equations you end up with an "identity." Both sides of the equation are the same.

x - 1/3(3x) = 0 . 1/3 of 3x is 1x

x - x = 0  any number minus itself is 0

or add x to both sides  x-x+x = 0 + x  

x = x is an identity. An identity has infinite solutions.

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

3x + 2 -x = 2 + 2x

2x +2 = 2 + 2x . same thing! Infinite solutions.

Negation of square root is never considered a number while rest any number comes under the category of the Real number

The Numbers here are divided into two categories: Real and Imaginary. In addition to being divided into Rational and Irrational numbers. In the category of rational numbers, fractions and integers  fall under the category. The decimal numbers which are unconvertable to the fraction  form are known as irrational numbers. This means that here in the question √-15 = 15i(where i = √-1, the imaginary number)

Hence √-15 is not considered a number while  -1.96312... comes under the category of a Real Number.

The measure of angle x is 140°

For given question,

We are given that a pair of parallel lines is cut by a transversal line .

Let a pair of parallel lines are PQ and RS and the transversal line AB cut the parallel lines PQ and RS.

We are given that an exterior angle on the left side of the transversal line is 40 degrees.

The interior angle on the right side of transversal line is x which is not vertical opposite to exterior angle = 40 degrees

We know that when two lines are parallel and cut by a transversal line then corresponding angles are congruent.

So, angle MNR = 40°

Also, ∠MNR + ∠MNS = 180°           ...............(linear pair of angles)

⇒ 40° + x = 180°

⇒ x = 140°

Therefore, the measure of angle x is 140°
