Answer:

10^2

Step-by-step explanation:

when bases are same and exponents are in division we subtract the exponents.

so 10^6-4 = 10^2

Answer:

10^2

Step-by-step explanation:

10^6 / 10^4 =

10 x 10 x 10 x 10 x 10 x 10 <------- 6 times 10

------------------------------------

10 x 10 x 10 x 10 <--------- 4 times 10

Simplify and you get

10 x 10 = 10^2

Answer:

<ZUVW = 12 degrees

<ZXYZ = 78 degrees

Step-by-step explanation:

x - 10 + 4x - 10 = 90

5x -20 = 90

5x = 90 + 20

x = 110/5

x = 22

mZUVW = 22 - 10 = 12 degrees

mZXYZ = 4(22) - 10

= 78

Answer:

in two bouquets of flowers there would be, 12 roses and 20 white carnations.

Step-by-step explanation:

In each bouquet there are 6 roses and 10 white carnations, if there's 2 bouquets of flowers that means that there 2 x 6 and 2 x 10.

2 x 6 (or 6 + 6) = 12

2 x 10 (or 10 + 10) = 20

so in two bouquets there are 12 roses and 20 white carnations.

because in a single bouquet there are 6 roses and 10 white carnations so just double it!

What is the slope of the line that passes through the two points? (-3, 2) and (-1, 9)

A line passes through the points (–3, 1) and (–1, 9).

A.

-4

B.

-1/4

C.

4

D.

1/4

Answer:

D

Step-by-step explanation:

d is incorrect because it's saying the vertical (x) is over the horizontal change (y) and we know that's wrong because it's y/x or rise/run

The option that does not correctly refer to the slope of a line is:

a. m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]

Option A is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

We have,

The slope of a line:

a.

m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]

The slope formula is:

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

So,

m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex] is not correct.

b. it represents the steepness of a line.

The slope of a line is the steepness of the given line on the graph.

It is correct.

c. m = rise/run

The slope can also be termed as rise/run.

It is correct.

d. it is the ratio of the vertical change to the horizontal change​

The slope of a line is given as:

m = Vertical change / Horizontal change

It is correct.

Thus,

The option that does not correctly refer to the slope of a line is:

a. m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]

Option A is the correct answer.

Answer:

(0,0) and (6,12)

Step-by-step explanation:

8x - x^2 = 2x

8x -2x -x^2 =0

6x -x^2 = 0 then factor out a common x

x (6-x) = 0

so x =0 or 6-x=o

x=6

so if x=o y=2x=2(0)=0

and if x=6 y =2x =2(6)= 12

Answer:

48.3 cm is the lower and upper bound of the perimeter.

Step-by-step explanation:

For any equilateral triangle, by definition, the

lengths of the sides of the triangle are the same.

Thus, the perimeter of the triangle is 16.1 + 16.1 + 16.1 = 3(16.1) = 48.3 cm.

Thus, the upper and lower bounds are the same and are both equal to

48.3 cm.

Answer:

What equation will model the situation?

✔ x/3 = 4

How many servings did the original recipe make?

✔ 12

Step-by-step explanation:

Hope this helps!

The equation that represents the situation is x/3 = 4. And the number of servings that the original recipe makes will be 12.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Gary is making a dish yet they just necessities 1/3 of the first serving size. In the event that the quantity of servings Gary needs is 4.

Let 'x' be the number of servings. Then the equation is given as,

x/3 = 4

Simplify the equation, then we have

x / 3 = 4

x = 12

The condition that addresses what is happening is x/3 = 4. What's more, the number of servings that the first recipe causes will be 12.

Answer:

Step-by-step explanation:

7x -1 +6x -1 = 180, group like terms

7x+6x -1 -1 = 180, combine like terms

13x -2 = 180, add 2 to both sides

13x -2+2 = 180+2 , solve the additions

13x = 182, divide both sides by 13

Answer:

shade the square that is 1 above the bottom right

To make a pattern with rotational symmetry order 2 we need to shade the square that is 1 above the bottom right.

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same. Many geometrical shapes appear to be symmetrical when they are rotated 180 degrees or with some angles, clockwise or anticlockwise.

Given is a figure of square box, of 5x5, we need to complete the shaded part so, that the resulting figure will be rotational symmetric,

Since, the figure needs to be rotational symmetric, that means, the figure will be same no matter how many times we rotated it,

If we shade the one square which is the last box of the fourth line, then it will be a figure which is rotational symmetric.

Hence, to make a pattern with rotational symmetry order 2 we need to shade the square that is 1 above the bottom right.

C. 9

Step-by-step explanation:

15/100*60

3/20*60

180/20

9

Answer:

The answer is 9

Step-by-step explanation:

15% * 60

"OF" mean multiplication so we multiple

¹⁵/100 * 60

we cancel "Zero cancel Zero"

we left with

¹⁵/10 * 6

but we can make the fraction to be uniform

so we say ¹⁵/10 * ⁶/1

we multiply

15 * 6=90

10 * 1=10

⁹⁰/10

we divide

10 into 90 is 9

10 into is 1

so we say ⁹/1 is the same as 9.

Hence our answer is 9
