The answer is True -Apex

Answer:

30 boxes

Step-by-step explanation:

~ You begin with the bottom row, which has 10 boxes.

~ You do 10 - 2 to get the number of boxes in the next layer, which is 8.

~ You then take 8 - 2, which is 6 for the next layer up.

~ Take 6 - 2, which is 4 for the next layer up.

~ Take away another two: 4 - 2 is 2.

~ When you take 2 away from 2, you get 0, so you have no more boxes.

~ Then, you add all the different amounts of boxes for each layer:

-> 10 + 8 + 6 + 4 + 2

-> Group smaller numbers together to get two bigger ones:

-> 18 + 12

= 30

Answer:

y = [tex]-\frac{1}{3} x[/tex] + 2

Step-by-step explanation:

The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:

Slope(s) = Change in y ÷ change in x

s = [tex]\frac{0 - -6}{2 - 0}[/tex] = 3

The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 = [tex]-\frac{1}{3}[/tex]

Reason: The product of slopes of lines perpendicular to each other have to be -1

So the slope of the perpendicular line that passes through (-6,4) is [tex]-\frac{1}{3}[/tex]

As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x

Taking another point (x,y) on the line,

[tex]-\frac{1}{3}[/tex] = [tex]\frac{y - 4}{x - -6}[/tex]

[tex]-\frac{1}{3}[/tex] = [tex]\frac{y - 4}{x + 6}[/tex]

y - 4 = [tex]-\frac{1}{3}[/tex]x - 2

y = [tex]-\frac{1}{3}[/tex]x + 2

To find the slope-intercept equation of a line that passes through a given point and is perpendicular to another line, we can determine the slope of the given line and use it to find the equation.

To find the slope-intercept equation of a line, we need to know the slope and the y-intercept. Since the line that this problem is referring to is perpendicular to a line with an x-intercept of 2 and a y-intercept of -6, we can determine the slope of the line we are looking for by taking the negative reciprocal of the slope of the given line.

The slope of the given line is found using the formula: slope = (y2 - y1) / (x2 - x1)

Once we have the slope, we can use the point-slope form of a linear equation to find the equation of the line that passes through (-6,4) and has the determined slope. Finally, we can rearrange the equation to obtain the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept.

Answer:6/36

Step-by-step explanation:

The probability of rolling a number less than 5 and even on a die is 1/2.

To find the probability of rolling a number less than 5 and even, we need to determine the number of outcomes that satisfy both conditions and divide it by the total number of possible outcomes.

There are three outcomes that satisfy both conditions: {2, 4, 6}. The total number of possible outcomes is six since a die has six sides.

Therefore, the probability of rolling a number less than 5 and even is 3/6, which simplifies to 1/2.

Answer:

270,000

Step-by-step explanation:

So, you have a number of people (15) that can stand comfortably within a certain area (5x8 ft = 40 sq feet).  And you need to find out how many people can fit in the whole park area.

First step is to find out how big the park is, in square feet, so we can then evaluate the number of people that we can fit in.

You had the right number for calculating the area of the park:

A = 400 yards x 200 yards = 1,200 feet x 600 feet = 720,000 sq feet

Now, how many people can we fit in there?  Let's use a simple cross-multiplication (x being the number of people fitting in the whole park, what we are looking for):

[tex]\frac{x}{720 000} = \frac{15}{40}[/tex]

By isolating x, we have x = (720,000 * 15) / 40 = 10,800,000 / 40 = 270,000

So, the park could accommodate 270,000 people.

That is of course if there are no trees, no benches, no kids playground or any other infrastructure in the park.

It’s a rational number.

Hope this helps!

Answer with step-by-step explanation:

Ordered pairs that satisfy the given equation:

x  0  1  2  3  4

y  5  3  1  -1  -3

To find the x-intercept, we will substitute y = 0 and solve for x to get:

[tex]0 = -2x + 5[/tex]

[tex] -2x = -5[/tex]

[tex]x = 5/2[/tex]

x-intercept = (5/2, 0)

To find the y-intercept, we will substitute x = 0 and solve for x to get:

[tex]y = -2(0) + 5[/tex]

[tex]y = 5[/tex]

y-intercept = (0, 5)

Answer: option d.

Step-by-step explanation:

To create a table of five ordered pairs that satisfy the equation, you need to give values to the variable "x" and substitute these into the function to find the corresponding value of "y":

For [tex]x=-2[/tex]

[tex]y = -2(-2) + 5=9[/tex]

For [tex]x=-1[/tex]

[tex]y = -2(-1) + 5=7[/tex]

For [tex]x=0[/tex]

[tex]y = -2(0) + 5=5[/tex]

For [tex]x=1[/tex]

[tex]y = -2(1) + 5=3[/tex]

For [tex]x=2[/tex]

[tex]y = -2(2) + 5=1[/tex]

Then, you can make the table:

x   -2  -1  0  1  2

y   9  7  5  3  1

To find the  x-intercept, substitute [tex]y=0[/tex] into the function and solve for "x". Then:

[tex]0 = -2x + 5\\\\x=\frac{-5}{-2}\\\\x=\frac{5}2}[/tex]

This is: ([tex]\frac{5}{2}[/tex], 0)

To find the  y-intercept, substitute [tex]x=0[/tex] into the function and solve for "y". Then:

[tex]y= -2(0) + 5\\\\y=5[/tex]

This is: (0,5)

The y-intercept is the point (0,-2)

The x-intercept is the value of x when the value of y is equal to zero

Answer:

  15 inches

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of its sides. A square has 4 sides, all the same length. We can either add up the side lengths, or we can recognize that multiplication of one side's length by 4 is a useful alternative.

  perimeter = 4 × (3 3/4 in)

  = (4×3 +4×3/4) in

  = 12 in + 3 in = 15 in

Answer:

The center is (-5,1)

and

the radius is 3

Step-by-step explanation:

The given equation of the circle is

[tex](x+5)^2+(y-1)^2=9[/tex]

We can rewrite this equation in the form;

[tex](x-h)^2+(y-1)^2=r^2[/tex]

This implies that;

[tex](x--5)^2+(y-1)^2=3^2[/tex]

When we compare, we get;

(h,k)=(-5,1) which is the center and r=3 the radius.

The answer is:

The center of the circle is located on the point (-5,1) and the radius is equal to 3 units.

To determine the center and the radius of a circle from its equation, we need to look for "h" and "k", being "h" the x-coordinate of the center and "k" the y-coordinate the center, then, calculate the radius.

Since we are given the ordinary equation of the circle, we can find the radius and the center directly.

The ordinary equation is:

[tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]

Where,

h is the x-coordinate of the center

y is the y-coordinate of the center

r is the radius.

So, we are given the circle:

[tex](x+5)^{2} +(y-1)^{2} =9[/tex]

Which is also equal to:

[tex](x-(-5))^{2} +(y-(1))^{2} =9[/tex]

Where,

[tex]h=-5\\k=1[/tex]

[tex]r^{2}=9\\\sqrt{r^{2}}=\sqrt{9} \\r=3units[/tex]

Hence, the center of the circle is located on the point (-5,1) and the radius is equal to 3 units.

72 fish total. 12 fish in each tank.

_________________________

g=Goldfish

t=Tetras

n=Number of fish tanks

*If I got it wrong, let me know*

Final answer:

The total number of fish in the tanks is 72.

Explanation:

To find the total number of fish in the tanks, we need to multiply the number of tanks by the sum of the goldfish and Tetras in each tank. Based on the information given, there are 6 tanks, and each tank has 7 goldfish and 5 Tetras.

So, the total number of fish (f) in the tanks can be calculated as:

f = (7 goldfish + 5 Tetras) * 6 tanks

f = (7 + 5) * 6

f = 12 * 6

f = 72

Therefore, the total number of fish in the tanks is 72.
