A cat adoption facility takes in an average of 6 cats per day. The facility has to keep their cat occupancy below 300. Currently, the facility has 258 cats. If none of their cats get adopted, how many more days, x, can the facility continue to take in cats? Select the inequality that includes the largest number of days this facility can continue to take in cats without exceeding its occupancy limit.
A. x < 5
B. x < 7
C. x < 42
D. x < 36
The highest number of days this institution can continue to accept cats without going over its allowed occupancy is included in the inequality (C) x<42.
What is inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.
The majority of the time, size comparisons between two numbers on the number line are made.
In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other.
Hence, inequality emerges from a lack of balance.
So, what we can do is add 6 in 285 till it reaches 300.
258 + 6 + 6 + 6 + 6 + 6 + 6 + 6 = 300
6 is added 7 times, then:
6*7 = 42
Then the correct inequality would be x < 42.
Therefore, the highest number of days this institution can continue to accept cats without going over its allowed occupancy is included in the inequality (C) x<42.

11. You place $4,000.00 in a bank account with an interest rate of 5.25% APR and another $2,000.00 in an account with an interest rate of 6.00% APR. after 6 months, what is the difference in interest that the accounts earn?
Answer:
$45
Step-by-step explanation:
I = prt
I = interest earned
p = principal = amount invested
r = interest rate; 5.25% = 5.25/100 = 0.0525
t = time in years; 6 months = 0.5 years
$4,000.00 at 5.25% interest
I = 4000 × 0.0525 × 0.5 = 105
$105 interest in 6 months
$2,000.00 at 6.00% interest
I = 2000 × 0.06 × 0.5 = 60
$60 earned in 6 months
$105 - $60 = $45
The difference is $45.
Draw a triangle with an area of 21 square units in a coordinate plane where the vertices are not all in the same quadrant?
The graph of the triangle is on the image at the end.
How to draw the triangle?Remember that the area of a triangle of base B and height H is:
A = B*H/2.
Here we want to have an area of 21, then we can use:
B = 6
H = 7
Then:
A = 6*7/2
A = 3*7 = 21
So we must have a base of 6 units and a height of 7 units, then the vertices that we can have are:
(-3, 0), (3, 0), (-3, 7)

You have $28.75 left to spend on diapers for Jake.
What is the percentage?
Percentage refers to a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%". For example, if 30 out of 100 students in a class are girls, the percentage of girls in the class is 30%. Percentages are commonly used in many fields, such as finance, statistics, and science, to express proportions, rates, and changes over time.
The total percentage of money spent on the blanket, toys, and clothes is 15% + 25% + 40% = 80%.
Therefore, the amount of money spent on Jake's supplies is $115, which is 80% of the total budget. We can set up the equation:
0.8x = 115
Solving for x, we get:
x = 115 ÷ 0.8 = $143.75
So, the total budget for Jake's supplies is $143.75.
To find out how much money is left for diapers, we need to subtract the amount spent on blanket, toys, and clothes from the total budget:
$143.75 - 15% of $143.75 - 25% of $143.75 - 40% of $143.75
= $143.75 - $21.56 - $35.94 - $57.50

How do you get to -3
Answer:
y = -3
Step-by-step explanation:
You want the equation of a line with slope 0 through the point (-2, -3).
Point-slope formThe point-slope form equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
Adding k to both sides gives the "y =" form ...
y = m(x -h) +k
ApplicationWhen m=0 and (h, k) = (-2, -3), this becomes ...
y = 0(x -(-2)) + (-3)
y = -3 . . . . . . simplified
__
Additional comment
Anything times 0 is 0. So, the product 0(x +2) is 0.
Anything added to 0 is unchanged. So, the sum y = 0 -3 is y = -3.
When the slope is zero we get y= -3.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
As, the Point-slope form
The point-slope form equation for a line with slope m through point (h, k) is

A smart phones have grown in popularity, regular cell phones have fallen out of favor. As a result, one electronics retailer estimates that 28% fewer regular cell phones will be sold every year. If the retailer sells 917160 regular cell phones this year, how many will be sold 7 years from now?
The retailer estimates that about 254,623 regular cell phones will be sold 7 years from now.
Since the retailer estimates that 28% fewer regular cell phones will be sold every year, this means that the number of regular cell phones sold each year will be 72% of the number sold the previous year. We can use this information to find the number of regular cell phones sold 7 years from now as follows:
Let x be the number of regular cell phones sold 7 years from now. Then we have:
x = 0.72^7 * 917160
where 0.72 is the percentage of regular cell phones sold each year.
Using a calculator, we get:
x ≈ 254,623
Therefore, the retailer estimates that about 254,623 regular cell phones will be sold 7 years from now.

solve the system 2xy+3=4y 3xy+2=5y
The solution to the system 2xy+3=4y 3xy+2=5y is (x, y) = (22/5, -30/29).
How to solve the system equation?Starting with the first equation:
2xy + 3 = 4y
We can rearrange it to solve for one of the variables in terms of the other:
2xy - 4y = -3
2y(x - 2) = -3
y = -3/(2(x - 2))
Now we can substitute this expression for y into the second equation:
3x(-3/(2(x - 2))) + 2 = 5(-3/(2(x - 2)))
Multiplying both sides by 2(x - 2) to clear the fraction:
-9x + 4(x - 2) = -30
-9x + 4x - 8 = -30
-5x = -22
x = 22/5
Now we can use this value of x to solve for y:
y = -3/(2(22/5 - 2))
y = -30/29
Therefore, the solution to the system is (x, y) = (22/5, -30/29).

g(x) = 4x + 3, so g(5) = 4(5) + 3 = 23.
Now we apply h to g(5):
h(g(5)) = h(23) = -(23) + 2 = -21
Therefore, (h.g(5)) = -21.
Answer:
Step-by-step explanation:
To find (h o g)(5), we need to first find g(5), and then evaluate h at that value.
We are given that g(x) = 4x + 4, so we can find g(5) by substituting x = 5:
g(5) = 4(5) + 4 = 24
Now we evaluate h at g(5):
h(g(5)) = h(24)
We know that h(x) = -x + 2, so we can evaluate h(24) by substituting x = 24:
h(g(5)) = h(24) = -(24) + 2 = -22
Therefore, (h o g)(5) = -22.
Three right triangles surround a shaded triangle; together they form a rectangle measuring 12 units by 14 units. The figure below shows some of the dimensions but is not drawn to scale. Is the shaded triangle a right triangle?
Answer:
To determine whether the shaded triangle is a right triangle, we need to use the fact that the three right triangles together form a rectangle.
Let's label some of the dimensions as shown in the diagram:
[asy]
unitsize(0.25cm);
pair A = (0,0), B = (10,0), C = (8,6), D = (6,0), E = (8,0), F = (10,6), G = (8,2);
draw(A--B--F--C--cycle);
draw(D--E);
draw(C--G);
label("$10$", (A+B)/2, S);
label("$6$", (C+F)/2, N);
label("$8$", (B+E)/2, E);
label("$2$", (C+G)/2, E);
label("?", (D+G)/2, NE);
label("$?$", (G+E)/2, S);
fill(C--G--D--cycle, gray(0.7));
[/asy]
The dimensions of the rectangle are 12 units by 14 units, so we know that:
\begin{align*}
10 + 8 &= 18 \\
6 + 2 + ? &= 14
\end{align*}
Simplifying the first equation, we get $8 = 14 - 6$. Substituting this into the second equation, we get:
$$2 + ? = 8$$
Therefore, the length of the shaded side of the triangle is 6 units. Now we can use the Pythagorean theorem to determine whether the shaded triangle is a right triangle. Letting $x$ be the length of the other leg of the shaded triangle, we have:
\begin{align*}
x^2 + 6^2 &= 8^2 \\
x^2 + 36 &= 64 \\
x^2 &= 28 \\
x &= 2\sqrt{7}
\end{align*}
Since $2\sqrt{7}$ is not an integer, we can conclude that the shaded triangle is not a right triangle.

Consider the difference of squares identity
For the polynomial 9x² - 49, the values of a and b include the following:
a = 3x
b = 7
What is a difference of two (2) squares?In Mathematics, the standard form for a difference of two (2) squares is modeled or represented by this mathematical expression:
a² - b² = (a + b)(a - b).
Where:
a and b are numerical values (numbers or numerals).
Based on the information provided, we have the following polynomial function:
9x² - 49
By using the sum-product pattern, we have the following:
9x² + 21x - 21x - 49
By writing the common factor from the two pairs, we have the following:
(9x² + 21x) + (-21x - 49)
3x(3x + 7) - 7(3x + 7)
By rewriting in factored form, we have the following:
9x² - 49 = (3x - 7)(3x + 7)

Pls help I’m not sure about this data
Answer: D - The mean of the date is greater than the median
Step-by-step explanation:
First, you line all the numbers up from least to greatest:
25, 26, 31, 33, 38, 39, 48, 58
Next, you find the median, or in this case, 35.5
Now you find the mean, and do that by adding all the numbers up (298) and then divide that by the number of people, or 8, which would be 37.25
Thus, the mean is greater than the median
Answer:
D
Step-by-step explanation:
Original data set:
25, 26, 31, 39, 33, 56, 38, 48
Data in increasing order:
25, 26, 31, 33, 38, 39, 48, 56
mean = (25 + 26 + 31 + 39 + 33 + 56 + 38 + 48)/8 = 37
median = (33 + 38)/2 = 35.5
