Find the sum of 5.21 × 1019 and 3.149 × 1017.

8.359 × 1019
5.24149 × 1019
5.24149 × 1036
8.359 × 1036

Answer:

-48c - 37d

Step-by-step explanation:

Multiply both numbers by -12.

The expanded form of the expression is -48c+36d

According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Given that, we have to expand the expression -12(4c - 3d) using the Distributive Property,

We know that the rule for distributive property is :

a(b+c) = ab+ac

Therefore,

-12(4c - 3d)

= -12(4c)+12(3c)

= -48c+36d

Hence, the expanded form of the expression is -48c+36d

Answer:

Choice C

Area(DEFG) + Area(GHIA) = Area(ABCD)

Step-by-step explanation:

This is solved using the Pythagorean theorem which states states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides(Wikipedia)

Area of the square on the hypotenuse = Area(ABCD)
Sum of the areas on the other two sides = Area(DEFG) + Area(GHIA)

So we get

Area(ABCD) = Area(DEFG) + Area(GHIA)

which can be re-written as
Area(DEFG) + Area(GHIA) = Area(ABCD)

which is choice C

Answer:

76°

Step-by-step explanation:

Use the Exterior Angle Property. The Exterior Angle Property states that an exterior angle of a triangle is equal to the sum of it's two opposite non adjacent interior angles.

In this case, set the exterior angle equal to the sum of the two given interior angle measurements:

(c) + (c - 26) = c + 50

First, simplify, combine like terms. Like terms are terms that share the same amount of the same variable:

c + c - 26 = c + 50

(2c) - 26 = c + 50

Next, isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Subtract c and add 26 to both sides of the equation:

2c (-c) - 26 (+26) = c (-c) + 50 (+26)

2c - c = 50 + 26

c = 76

76° is your answer.

Step-by-step explanation:

To find how many times QRST is bigger that ABCD, we can use the equation

1.4*x=7

or

7/1.4=5.

Since we now know QRST is 5 times bigger, we can multiply 2.3 by 5 to get the length of RS.

2.3*5=11.5

Step-by-step explanation:

It's 12/5 or also 2.4

Answer:

yes

Step-by-step explanation:

remember how to do fraction operations :

a/b / c/d = a×d / b×c

that is why you can also say it is the same as the multiplication with the upside-down fraction

a/b / c/d = a/b × d/c = a×d / b×c

in your case here

4/5 / 1/3 = 4/5 × 3/1 = 12/5

and that is definitely greater than 1.

Answer:

A" (-3, 0)

B" (9, 9)

C" (9, 0)

Step-by-step explanation:

The hint explains how to get the final coordinates.

The original figure ABC has vertices

A (-3, -1)
B (1, 2)

C (1, -1)

There are two separate transformations for this triangle, so let's take it one step at a time

The first transformation is a translation by the vector <2, 1>, This means we get a new figure A'B'C' where we add 2 to each of the x coordinates of the original figure and 1 to the y coordinates of the original figure

For A which is (-3,-1) the transformed coordinate becomes:
A -> A' -> A' (-3 + 2, -1 + 1) => A'(-1, 0)

Similarly

B(1, 2) -> B' is B'(1 + 2, 2 + 1) => B'(3, 3)

C(1, -1) -> C'(1 + 2, -1 + 1) or C'(3, 0)

So the first transformation results in a triangle A'B'C' with the following coordinates:

A'(-1, 0)
B'(3, 3)
C'(3, 0)

The second transformation is a dilation of A'B'C' which results in an expansion or compression of the image depending on the scale factor. Here the scale factor is 3 so the image is expanded by a factor of 3

Dilation simply requires you to multiply both x and y coordinates oof A'B'C' by 3

A' (-2 , 0) -> A"(-1 x 3, 0 x 3) => A"(-3, 0)
B'(3, 3) -> B"(9, 9)
C'(3, 0) -> C"(9, 0)

I have attached two images showing each of the transformations separately to give you a better idea

Answer: The x and y coordinates that define the location of a point are the coordinates of that point in a two-dimensional coordinate system.

In a two-dimensional coordinate system, a point is represented by an ordered pair of numbers (x, y). The first number, x, represents the point's position along the horizontal axis, and the second number, y, represents the point's position along the vertical axis.

For example, if a point is located at the position (3, 4) in a two-dimensional coordinate system, this means that the point is 3 units to the right of the vertical axis and 4 units above the horizontal axis.

The x and y coordinates of a point can be used to plot the point on a graph or to find the distance between two points using the distance formula: d = √((x2 - x1)^2 + (y2 - y1)^2)

Answer:

the answer is The imputs are {-1,0, 3,4}

Answer:

-1,0, 3,4

Step-by-step explanation:

Kiosks only occur when the y-coordinate is a multiple of 3. The closest to the 40 units of northern land would be at 39. 39 divided by 3 would mean Tomas placed an additional 13 kiosks after the first. With the x-coordinate incrementing 1 unit east each time, the x-coordinate of the last kiosk endpoint is 3+13 or 16. Thus the foot of the trail ends at (16,39).

Answer:

The last pin will be placed at (16,39).

Wow, it genuinly is 69

Step-by-step explanation:

it has to add up to 360 degrees

so 111 + 111 = 222 since those two angles are the same

then 360 - 222 so you get the sum of the two smaller angles

which is 138

and 138/2 is 69

Answer: 69

Step-by-step explanation: 111 + 111 = 222

360 - 222 = 138  

138 / 2 = 69
