what is the exponent for the expression 6x6x6x6x6x6x6?

Answers

Answer:7 is the exponent

Step-by-step explanation:

Answer:

[tex]6^7[/tex]

Step-by-step explanation:

Exponents can be expressed through repeated multiplication, meaning that the amount of times one number is being repeated, would be the same amount as put in an exponent. Therefore :

6 * 6 * 6 * 6 * 6 * 6 * 6

6 is being repeated, therefore it's the constant.

6 is repeated 7 times, therefore the exponent is 7.

Actually Welcome to the Concept of the linear equation in two variables.

So we have to form two equations to solve this.

Let the number of children be 'x' and number of adults be 'y'.

hence, we get as,

x+y = 630 ..... (1)

and also, to their total cost spending, we get as,

1.5x + 2.25y = 1170 ...... (2)

solving (1) and (2) we get as,

Number of children were = 330

and Number of Adults were = 300

please help me, u have no clue what to do. all it says is find the slope of the line that passes through the given two points using ratio method.​

Answers

Answer:

Triangle y = 7

Triangle x = -3

Slope = - 7/3

Step-by-step explanation:

Formula:

slope (or m) = (y2 - y1)/(x2 - x1)

Plug numbers into formula

m = 8 - 1 / 4 - 7

m = 7 / -3

Cannot be simplified further

Slope = - 7/3

The triangle before y is asking for the difference, meaning what number do you get after taking y2 (8 in this problem) and subtracting y1 (1 in this problem) from it.

8 - 1 = 7 which forms the numerator for our slope

The same goes for the triangle before x. Find the difference

x2 - x1 = 4 - 7 = -3. This forms the denominator of our slope

Solving systems of equations by graphing. how do you do this

Answers

Answer:

Solve systems of equations by graphing

A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Example

[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]

Graph the equations in a coordinate plane

The two lines intersect in (-3, -4) which is the solution to this system of equations.

Find the equation of the line by using y=mx+b
I tried to put the answer but it keeps asking for more

Answers

Answer:

Step-by-step explanation:

y=mx+b

m=(y2-y1)/(x2-x1), we have points (-3,6) and (9,-5)

m=(-5-6)/(9-(-3))

m=-11/12 so now we have

y=-11x/12+b, using point (9,-5) we can solve for b

-5=-11(9)/12+b

-5=-99/12+b

b=39/12

y=(-11x+39)/12

That is the line, m=-11/12 and b=39/12 or as a decimal b=3.25. You had b so not sure what the problem is. Though the question in the picture asks what the line is. The line is

y=-11x/12+13/4 so maybe they want the entire function instead of entering what b is.

The table gives the probabilities that orphaned pets in animal shelters in six cities are one of the types listed. The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is _____ %. The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is _____ %. (Round to the nearest hundredth.)

Answers

Answer:

For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%

Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92

Step-by-step explanation:

there ya go....

Answer:

i think you add all the dogs which give you 2.65+2.46+3.67+2.91 = 11.69%

then for the  chihuahua  you add  3.44/11.69=0.2942= 24.92

The weight of 25 folding chairs is 15 kg. How many
chairs can be loaded on a truck having a capacity of
carrying 2025 kg load?​

Answers

Answer:

3,375 chairs

Step-by-step explanation:

The weight of 25 folding chairs is 15 kg

Number of folding chairs : weight

= 25 : 15

How many chairs can be loaded on a truck having a capacity of

carrying 2025 kg load?

Let number of folding chairs = x

Number of folding chairs : weight = x : 2025

Equate both ratios

25 : 15 = x : 2025

25/15 = x/2025

Cross product

25 * 2025 = 15 * x

50,625 = 15x

x = 50,625/15

x = 3,375

Number of folding chairs = 3,375 chairs

A tree is broken at a height of 7m from the ground and its top touches the ground at distance of 24m from the base of the tree. Find the original height of the tree. pls help with steps

Answers

let the broken part of tree be x
then total height of tree=7+x
since it form a right angled triangle with base 24m and height 7m and hypotenuse be x
then by using Pythagoras theorem
(hypotenuse)^2=(base)^2+(height)^2
x^2=24^2+7^2
x^2=576+49
x^2=625
x=25
therefore height of tree =x+7=25+7=31

When the two boys were going to high school, Ernest often came over in the evening to study with Claude, and while they worked at the long kitchen table Mrs. Wheeler brought her darning and sat near them, helping them with their Latin and algebra. Even old Mahailey was enlightened by their words of wisdom.Mrs. Wheeler said she would never forget the night Ernest arrived from the Old Country. His brother, Joe Havel, had gone to Frankfort to meet him, and was to stop on the way home and leave some groceries for the Wheelers. The train from the east was late; it was ten o'clock that night when Mrs. Wheeler, waiting in the kitchen, heard Havel's wagon rumble across the little bridge over Lovely Creek. She opened the outside door, and presently Joe came in with a bucket of salt fish in one hand and a sack of flour on his shoulder. While he took the fish down to the cellar for her, another figure appeared in the doorway; a young boy, short, stooped, with a flat cap on his head and a great oilcloth valise, such as pedlars carry, strapped to his back. He had fallen asleep in the wagon, and on waking and finding his brother gone, he had supposed they were at home and scrambled for his pack. He stood in the doorway, blinking his eyes at the light, looking astonished but eager to do whatever was required of him. What if one of her own boys, Mrs. Wheeler thought. . . . She went up to him and put her arm around him, laughing a little and saying in her quiet voice, just as if he could understand her, "Why, you're only a little boy after all, aren't you?"Ernest said afterwards that it was his first welcome to this country, though he had travelled so far, and had been pushed and hauled and shouted at for so many days, he had lost count of them. That night he and Claude only shook hands and looked at each other suspiciously, but ever since they had been good friends.
