I need some help on this ASAP!!

.
Mckenzie and Cara both tried to find the missing side of the right triangle.

A right triangle is shown. One leg is labeled 5 and the other is labeled 13. A right angles is labeled in between the legs.

Mckenzie's Work Cara's Work
a2 + b2 = c2 a2 + b2 = c2
52 + 132 = c2 52 + b2 = 132
25 + 169 = c2 25 + b2 = 169
194 = c2 b2 = 144

Square root 194 equals square root c squared. Square root b squared equals square root 144.
13.93 ≈ c b ≈ 12

Is either of them correct? Explain your reasoning.

Answers

Answer 1

Answer:

the answer is

[tex]5 ^2 + 13 {}^{2} = c{}^{2} [/tex]

25+169=c squared

194=c squared

c= the square root of 194 or 13.93

I don't know what the b squared part of their answers are, so I would say neither are completely correct

Explain why 0 divided by any number is either 0 or infinity.

Answers

Step-by-step explanation:

Division as the inverse of multiplication

But any number multiplied by 0 is 0 and so there is no number that solves the equation. ... In general, a single value can't be assigned to a fraction where the denominator is 0 so the value remains undefined.

Answer:

0 divided by itself is undefined so we use infinity or 0 to describe it because infinity has no limits and it doesn’t really exist so I wouldn’t say it equals infinity or 0 but it is undefined. I hope it helps! Let me know if you need more help :D

Group of answer choices

1 over 3

1 over 5

Answers

Answer:

1/4

Step-by-step explanation:

The sides go from 4 units to 1 unit so the dilation must be 1/4

Answer:

1 over 4

Step-by-step explanation:

Step 1. The shape dilates smaller than itself so will always be less than 1

Step 2. We count P to 0 in the larger shape and see = 4 unit

and compare to P' to 0' in the smaller shape and see = 1 unit

Answer. The dilation is 1/4

Note, the letters are not MNOP so ensure you realise this.

At this pace, how long will it take her to knit the next 25 rows?

Enter your answer in the box.

Answers

Answer:

It will take 30 minutes!

Hope this helps! :D

Step-by-step explanation:

30 minutes
Since 10 rows=12 minutes
10rows + 10rows = 20 since each 10 rows is 12 minutes it’s
12 minutes+ 12 minutes = 24
But we still have the 5 rows so that would be have of 12 minutes and that’s 6 minutes so
24 minutes plus the 6 minutes is

Answers

Answer:

-6.809 > -6.812|

-6.809| < -6.812|

Step-by-step explanation:

Answer:

-6.809 > -6.812 and |-6.809| < |-6.812|

Step-by-step explanation:

-6.809 is greater than -6.812 because the number is more closer to zero.

A negative number more closer to zero is greater than a negative number that is farther away from zero.

Also, |6.809| <| -6.812| Because the absolute value for both numbers is 6.809 and 6.812 meaning the number 6.812 is greater than the number 6.809.

A company charges $3.00 for every 2 pounds of oranges sold plus a $3.00 shipping fee. Based on this information, which graph best shows this relationship between the cost of oranges, y, and the number of pounds, x?

Answers

b is the answer because of 3 dollars every 2 pounds

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Given that, a company charges $3.00 for every 2 pounds of oranges sold plus a $3.00 shipping fee.

What is graph?

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Let the total cost of oranges be y and the number of pounds of oranges be x.

So, the equation to represent the given situation is y=2x+3

By substituting x = 1, 2, 3, 4, 5,....we get

y = 2(1)+3=5

y = 2(2)+3 = 7

y = 2(3)+3 = 9

y = 2(4)+3 = 11

So, the coordinates to plot the graph are (1, 5), (2, 7), (3, 9) and (4, 11) and so on.

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

The solution of the given expression is 63.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here the given expression is :

3(a-2b)

where, a = -3

and, b = -12

Now, substitute the value of a and b in the given expression :

3(a-2b)

= 3(-3-2x -12)

= 3(-3 + 24)

= 3(21)

= 63

Therefore, the solution of the given expression is 63.
