Which of the following CANNOT be the length of AC?
Answers
now, if you took a look at that link above, let's see.
if we take AB and BC and lie them flat, by opening up the vertex at B, the longest that'd give us is 12+14 = 26, so AC can be at most LESS than 26 units, because if it's 26, then we end up with a flat-line and lose the triangle, so 25 or less is fine for AC.
can it be 30? well, how the dickens are AB + BC going to give 30 or more than 30 really? nope, not quite, it can't be.

What is the fraction in simplest form?
4/16
A.2/4
B.1/4
C.2/16
D.2/8
Answers
Answer: B) 1/4
The greatest common factor of 4 and 16 is 4. This is the largest factor that goes into both numerator and denominator
Divide the numerator and denominator by the GCF
4/4 = 1
16/4 = 4
This means 4/16 reduces to 1/4
Thinking in reverse, you can multiply top and bottom of 1/4 by 4 to get 4/16.

For which value of X is the row in the table of values incorrect? The function is the quadratic function Y=3/4x^2
Answers
Answer:
The row with x = 2 and y = 4 is incorrect. The y value should be y = 3 when x = 2.
==============================================================
Explanation:
Fractions can be a bit of a pain, so I'm going to be converting to decimal form to help with the computation; however, I will convert the y value results to mix number form so that it matches what the table shows.
Keep in mind that 3/4 = 0.75 when you use a calculator or long division. So a number like 2.75 means 2 & 3/4 (two and three quarters)
---------------
Let's check the first row. Plug in x = 0 and it leads to...
y = (3/4)*x^2
y = (3/4)*0^2
y = (3/4)*0
y = 0.75*0
y = 0
This shows us that row 1 is correct. When x = 0, y = 0 leading to (x,y) = (0,0).
-------------
Repeat the same basic outline of steps, but now use x = 2
y = (3/4)*x^2
y = (3/4)*2^2
y = (3/4)*4
y = 0.75*4
y = 3
So instead of 4, the proper y value is y = 3 when x = 2. This means row 2 is the answer (the row that has the incorrect values).
-------------
For the sake of completeness, let's see if the third row is correct or not. Plug in x = 3
y = (3/4)*x^2
y = (3/4)*3^2
y = (3/4)*9
y = 0.75*9
y = 6.75
y = 6 & 3/4
We see that x = 3 points to y = 6 & 3/4, so we have the correct values in this row. We can cross this off the list of choices.
-------------
Finally, let's check x = 5
y = (3/4)*x^2
y = (3/4)*5^2
y = (3/4)*25
y = 0.75*25
y = 18.75
y = 18 & 3/4
We get the proper y value. So we can also cross this off the list.

Denise bought a t-shirt at the sale price of $25 the original cost of the T-shirt was $40 what percent represents the discount that Denise received when buying the T-shirt
Answers
Answer:
37.50%
Step-by-step explanation:
Use the formula: Old Value minus New Value (in absolute value bars) divided by Old Value times 100
New Value = $25 / Old Value = $40
$40 - $25 = $15
$15 divided by $40 is 0.375
0.375 times 100 (0.375 x 100) is 37.50

Find two numbers such that one exceeds the other by 11 and their sum is 73.
Answers
Answer: 31 & 42
Step-by-step explanation:
1st #: x
2nd #: x + 11
1st# + 2nd# = sum
x + x + 11 = 73
2x + 11 = 73
2x = 62
x = 31
2nd #: x + 11 = 31 + 11 = 42
The problem is solved by creating two equations from the given conditions and then solving them to find the numbers. The result is that the two numbers are 31 and 42.
Explanation:We are looking for two numbers, let's call them x and y. According to the problem, one number exceeds the other by 11, so we can say that y = x + 11. Moreover, their sum is 73, so x + y = 73.
Now, we need to substitute y from the first equation into the second one. So x + (x + 11) = 73, which simplifies to 2x + 11 = 73. Subtracting 11 from both sides gives us 2x = 62. Dividing by 2, we find that x = 31. From the first equation, we can now determine the value for y as y = 31 + 11 = 42. Therefore, the two numbers are 31 and 42.

Leila has scored 33, 28, 24 and points in her three basketball games so far. How many points does she need to score in her next game so that her average (mean) is 27 points per game?
Answers
24 points.
The amount of points Leila needs to score in her next game so that her average is 27 points per game is: 24 points.
STEP-BY-STEP EXPLANATION:
Let the amount of points Leila needs to score in her next game so that her average is 27 points per game = x
27 = total no. of points / total no. of games
27 = ( 33 + 28 + 24 + x ) / ( 3 + 1 )
27 = ( 85 + x ) / 4
27 × 4 = 85 + x
85 + x = 108
x = 108 - 85
x = 24
Leila needs to score 23 points in her next game to have an average of 27 points per game.
Explanation:
To find out how many points Leila needs to score in her next game in order to have an average of 27 points per game, we need to use the formula for finding an average. The sum of all the points scored is 33 + 28 + 24 + x (the points in the next game), and we divide this sum by the number of games, which is 4. So, the equation is (33 + 28 + 24 + x) / 4 = 27. To solve for x, we multiply both sides of the equation by 4 to get 33 + 28 + 24 + x = 27 * 4. Simplifying this gives us 85 + x = 108. To isolate x, we subtract 85 from both sides of the equation, which gives us x = 108 - 85. So, Leila needs to score 23 points in her next game to have an average of 27 points per game.

HELP!! 30 POINTS AND WILL MARK BRAINLIEST One month, Henry's grandfather gives him a box of 523 baseball cards. Each month, starting the second month, Henry buys 24 baseball cards to add to this collection. What is the explicit rule for the number of baseball cards Henry has in his collection after n months? Enter your answer in the box.
Answers
Answer:
nth term = 523 + 24(n - 1
Step-by-step explanation:
This is modelled by an arithmetic series where first term a1 = 523 and common difference d = 24.
nth term = a1 + d(n - 1).
Here it is 523 + 24(n - 1) (answer)
Answer:
The answer is:24n+499
Step-by-step explanation:
As we know Henry's grandfather gave him a box of 523 baseball cards in the first month.
from the second month Henry start to collect 24 baseball cards each month.
if the total process took n months, so Henry himself collected 24 baseball cards for 'n-1' months.
so total cards collected by Henry in (n-1) months is=24(n-1)
hence, Henry's total collection is=number of baseball cards his grandfather gave him+number of baseball cards collected by Henry himself
=523+24(n-1)
=523+24n-24
=24n+499
find slope for 7x-2y=0.2
[tex]7x - 2y = 0.2[/tex]
Answers
Answer:
slope = -7/2
Step-by-step explanation:
To find the slope, we will solve the equation for y.
7x-2y=0.2
Subtract 7x from each side.
7x-7x-2y=-7x+0.2
-2y = -7x+0.2
Then we need to divide each side by -2
-2y/-2 = -7x/-2 + 0.2/-2
y = -7/2 x -0.1
This is in the form y= mx+b where m is the slope and b is the y intercept.
So the slope is -7/2 and the y intercept is -0.1

A water company offers industrial users two different packages. The users can either pay 77 cents per thousand gallons, or pay a fixed amount of $1,232,000 for unlimited water usage for one year. How much water does an industrial user need to use in one year for the fixed amount package to be the less expensive option?
Answers
The water used will be greater than 1600000 thousands of gallons for the fixed amount to be less expensive.
How to find amount of water used for it to be less expensive?The users can either pay 77 cents per thousand gallons, or pay a fixed amount of $1,232,000 for unlimited water usage for one year.
Therefore,
77 cents = 0.77 dollars
Hence,
The user can pay 0.77 per thousand gallons.
He can pay a fixed amount of $1,232,000 .
Therefore, the amount of water the company will use for the fixed amount to be less expensive is as follows;
let
x = amount of water use in thousand gallons
Using inequalities,
0.77x ≥ 1,232,000
x ≥ 1,232,000 / 0.77
x ≥ 1600000
Therefore, the water used will be greater than 1600000 thousands of gallons for the fixed amount to be less expensive.

What is the domain of f(x)=(1/2)^x
Answers
Answer:
Domain: all real numbers
Step-by-step explanation:
The domain of a function is the set of values that x can be replaced with.
In this function, x can be replaced by any real number, so the domain of the function is all real numbers.
Here we need to find the domain of the given function.
We will see that the domain is the set of all real numbers.
The first thing we need to do is to define the domain of a function.
For a given function f(x), we define the domain as the set of possible inputs that we can use on the function.
Usually, we start by defining the domain as the set of all real numbers and then remove from the domain the numbers that cause "a problem" with our function.
Where these "problems" are undefined operations, like the logarithm of a negative number or a zero in a denominator.
Particularly, in our function: f(x) = (1/2)^x
We do not have a denominator that can become zero nor a function that has problems with some given values of x (the exponent of a number can be any real number).
Concluding, because there is no problem with any real value, we can see that the domain is the set of all real numbers.
