Answer:

The perimeter is 24

Step-by-step explanation:

BD = AD and we know that AD is 3 so we know the little side is exactly 6 long.

Because they are right triangles, both of the long sides are equal.

AC is 9 so BC must also be 9.

We break this into 9 + 9 + 6 which equals 24

There is 6 members of the family

There are two girls, mrs. Simpson and the one daughter.

The percent that are girls would be 2 out of 6 = 2/6 = 33%

The boys would be 100% - 33% = 67%

The correct matches are;

1) (-7) (-1.2) =  8.4

2) 5 =  (-2 1/2) (-2)

3) -5 = (2.5) (-2)

4) (7) (-1.2) = - 8.4

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expressions are,

a) (-7) (-1.2)

b) 5

c) (-2 1/2) (-2)

d) -5

e) (2.5) (-2)

f) 8.4

g) (7) (-1.2)

h) -8.4

Now, Solve the expressions in simplest form;

a) (-7) (-1.2) = 8.4

b) 5 = 5

c) (-2 1/2) (-2) = -5/2 x - 2 = 5

d) -5 = -5

e) (2.5) (-2) = -5

f) 8.4 = 8.4

g) (7) (-1.2) = - 8.4

h) -8.4 = -8.4

Thus, The correct matches are;

1) (-7) (-1.2) =  8.4

2) 5 =  (-2 1/2) (-2)

3) -5 = (2.5) (-2)

4) (7) (-1.2) = - 8.4

Step-by-step explanation:

The ratio is simply the fractional representation of two values in their simplest form. The ratio of Cell A to Cell B is 20 which means that the size of Cell A is 20 times the size of Cell B.

Given that :

Cell size A = [tex]Cell A = 0.0005\times 10^{-5}\\\\Cell B = 0.0025\times10^{-7} \\\\Ratio = \frac{Cell A }{Cell B} \\\\Ratio = \frac{0.0005 \times 10^-5}{0.0025 \times 10^-7}[/tex]

[tex]Ratio = 20[/tex]

Therefore, the ratio of the size of Cell A to the size of Cell B is 20 : 1, which can be interpreted to mean that cell A is 20 times larger than cell B.

Answer:

(7x-15) = 180

7x = 195 (add 15 to both sides)

195 / 7 = 27.85

(x + 28) + (4x -3) + 27.85 = 180

5x + 53.85 = 180 (add like terms)

5x = 126.15 (subtract 53.85 from both sides)

x = 25.23 (dived both sides by 5)

A reflection over the x-axis, a vertical stretch by 2, a horizontal shift left 6, and a vertical shift down 3

Step-by-step explanation:

y=a|x-h|+k is the form for these types of equations.

a values describe the vertical stretch (skinnier) or shrink (wider)

h values represent the horizontal (left/right) change. The h value in the equation is negative, so make sure to take that into consideration.

k values represent the vertical (up/down) change

Step-by-step explanation:

Hiroaki is mistaken since the line should pass through the origin, negating the possibility of the proportionality constant being a simple whole number.

Whole numbers are defined as natural numbers plus zero (0). We are aware that the term "natural numbers" refers to a group of counting numbers beginning with 1, 2, 3, 4, and so forth. Whole numbers are a collection of numbers that don't contain any fractions, decimals, or even negative integers. It is made up of zero and positive integers. Alternately, we may define whole numbers as the collection of non-negative integers. The inclusion of zero in the set of whole numbers marks the main distinction between them and natural numbers.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole quantities.
