Answer:

7 or [tex]7^{2}[/tex]

Step-by-step explanation:

Each triangle has the surface area of 1.5, because 1 [tex]*[/tex] 3 = 3 / 2 = 1.5. You divide by two because it is half a rectangle instead of a full one. You multiply by four which would get you 1.5 [tex]*[/tex] 4 = 6. The square in the middle has the surface area of 1 because 1 [tex]*[/tex] 1 = 1. So you would get 7.

Step-by-step explanation:

Employing a ruler or metric tape, Ally can determine the length of 8 inches of string.

A length is a unit used to describe the measurement of a possession or a distance. It can be quantified in terms of inches, hands, yards, millimeters, meters, and miles, among other quantities.

Ally needs to apply the idea of assessing in order to determine the proper length of the string. Somebody can measure the measurement of the string with a ruler. If she doesn't have a ruler, she is able to measure the length of the required thread against an object of a string following: she already knows is a specific length, like one foot, for example.

To determine the length, the woman is able to determine the number of times the segment of string slips into the length that she wants string.

Answer: No, it isn't.

Step-by-step explanation: This graph shows a Translation, meaning the figure moved. Yes, the rotation of the second figure is 180 degrees, but it was also Translated downwards 2 points down and one to the right.

Yes, ΔP'Q'R' a 180° rotation about the origin of ΔPQR.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Midpoint of PQ: ((2+4)/2, (3+4)/2) = (3, 3.5)

QR: ((4+4)/2, (4+3)/2) = (4, 3.5)

RP: ((4+2)/2, (3+3)/2) = (3, 3)

Translate each midpoint to the origin by subtracting the coordinates of the midpoint from each vertex:

P translated: (2-3, 3-3.5) = (-1, -0.5)

Q translated: (4-4, 4-3.5) = (0, 0.5)

R translated: (4-3, 3-3) = (1, 0)

Rotate each translated vertex by 180° about the origin:

P' rotated: (-(-1), -(-0.5)) = (1, 0.5)

Q' rotated: (-0, -0.5) = (0, -0.5)

R' rotated: (-1, -0) = (1, 0)

Translate each rotated vertex back to its original position by adding the coordinates of the midpoint:

P' translated back: (1+3, 0.5+3.5) = (4, 4)

Q' translated back: (0+4, -0.5+3.5) = (4, 3)

R' translated back: (1+3, 0+3) = (4, 3)

We can see that the coordinates of P', Q', and R' match the coordinates of Q, R, and P respectively

ΔP'Q'R' is a 180° rotation about the origin of ΔPQR.

Hence, yes ΔP'Q'R' a 180° rotation about the origin of ΔPQR.

Answer:

To factor out -1/3 out of the expression -1/3x - 8, first divide -8 by -1/3 to get 24. Now just put 24 in the place of -8 in the original expression. Your final answer should be -1/3(x + 24). Hope this helps and have a phenomenal day!

Step-by-step explanation:

The expression for the factor, 1/3 out of the 1/3x - 7/3 is 1/3 (x - 7).

A factor is a number which entirely divides another number.

Let 8 is a number, so there 2 and 4 are factors of it.

The given expression is,

1/3x - 7/3

To find the factor 1/3 out of the expression,

Take 1/3 out from the expression,

Answer:

40.5 in²

Step-by-step explanation:

It's pretty easy if you find the surface area of each and every shape alone first.

I see 2 squares and 4 rectangles.

Let's start by finding the surface area of the squares:

-The formula to finding the area of a square is length x length.

L×L

1.5 in x 1.5 in= 2.25 in²

2.25 in is the surface area of 1 square

but we have two squares so you do 2.25 in × 2 to get the surface area of both squares.

2.25 in² × 2= 4.5 in² (this is the surface area of both squares)

Now we calculate the surface area of the four rectangles.

Formula: L×W (length × width)

6 in × 1.5 in = 9 in² (s.a of one rectangle)

Since we have four rectangles, we'll have to multiply it by 4

9 in² × 4= 36 in²

Now we add the total surface areas of both the squares and the rectangles.

4.5 in² + 36 in²= 40.5 in²

37 percent of the bacteria on the Petri dish is type 3

The percent of bacteria on the Petri dish of type 3 will be 36.84%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

There are nine different types of bacteria on the Petri dish.

A drawing shows some colonies of bacteria on the Petri dish. The number of bacteria in different colonies is as follows:

Colony  bacteria

     1          2

    2          1

    3          7

    4          4

    5          1

    6          1

    7          1

    8          1

    9          1

Then the percent of the bacteria on the Petri dish of type 3 will be given as,

P = [7 / (2 + 1 + 7 + 4 + 1 + 1 + 1 + 1 + 1)] x 100

P = (7 / 19) x 100

P = 36.84%

Answer:

  8.  20.8 units

  9.  isosceles

Step-by-step explanation:

The vertical altitude line divides the triangle into two congruent right triangles. Each has a horizontal leg of 4 units, and a vertical leg of 5 units. (You can find these lengths by subtracting coordinates, or by counting grid squares.)

slant sides

The hpotenuses of these right triangles are the short sides (PR, QR) of the larger triangle PQR. We can find their length using the Pythagorean theorem. Defining S as point (-2, -1), we have ...

  PS² +SR² = PR² . . . . . . . . . . . . the Pythagorean theorem relation

  4² +5² = PR² = 16 +25 = 41 . . . with numbers filled in

  PR = √41 . . . . . . . . . . . . . . take the square root

  PR ≈ 6.4 . . . . . . . . . . . round to tenths

horizontal side

The length of side PQ is 8 units, found by subtracting x coordinates ((2 -(-6)) = 8), by counting grid squares, or by doubling the length of PS (2(4) = 8).

perimeter

The perimeter of the triangle is the sum of its side lengths:

  perimter = PR +QR +PQ = 6.4 +6.4 +8 = 20.8

The perimter of triangle PQR is 20.8 units.

__

Sides PR and QR are congruent, so the triangle is isosceles.

Answer:

The number of sandwiches sold is 73. This is because it is multiplied by the expression for the money received per sandwich.

The cost to make each sandwich is S. This is stated in the first sentence of the problem.

The profit is 0.2S. This is because they sell each sandwich for an additional 20% of the cost ( S )

The amount of money the band receives is (S + 0.2S ). This is because it is the price per sandwich.
