PLEASE HELP!!! The total area of fictional Puget Loud, near Seapple, Washington, can be roughly estimated using a rectangular shape that is 110 miles long and 15 miles wide. In Puget Loud, orcas require approximately 5 mi² of territory per animal. Based on this information, how many orcas could live in Puget Loud? Show your work and place a box around your answer.
Answer:
[tex]330\ orcas[/tex]
Step-by-step explanation:
step 1
Find the total area of fictional Puget Loud
The area of the rectangular shape is
[tex]A=110*15=1,650\ mi^{2}[/tex]
step 2
Divide the total area by 5 mi² of territory per animal to find the number of orcas that could live in Puget Loud
[tex]1,650/5=330\ orcas[/tex]
Final answer:
To determine how many orcas could live in Puget Loud, calculate the total area (Length × Width) and divide it by the amount of space required per orca (5 mi²). The calculation gives us 330 orcas.
Explanation:
To estimate the number of orcas that could live in Puget Loud, we first need to calculate the total area of Puget Loud. We do this by multiplying the length by the width of the rectangular region.
Total area of Puget Loud = Length × Width
Total area of Puget Loud = 110 miles × 15 miles
Total area of Puget Loud = 1650 square miles
Next, we need to divide the total area of Puget Loud by the territory required per orca. Each orca requires approximately 5 square miles.
Number of orcas = Total area / Territory per orca
Number of orcas = 1650 mi² / 5 mi² per orca
Number of orcas = 330
Therefore, Puget Loud could potentially support 330 orcas.

Consider the ordered pairs (1,4), (-1,2), and (0,3). Which of the four equations below could have been used to generate these three ordered pairs?
Select one:
a. y = x + 3
b. y = -x + 3
c. y = -x - 6
d. y = -x - 3
Answer:
a. y = x + 3
Step-by-step explanation:
All three ordered pairs satisfy the first equation.
___
If you want to look into it a little further, you can notice that if you sort the ordered pairs by their x-values, you get ...
(-1, 2), (0, 3), (1, 4)
That is, the y-values increase (by 1) as the x-values increase (by 1).
All of the other answer choices have -1 as the coefficient for x, which means the y-values will decrease as x increases. None of these choices (b–d) is viable.

Bea's uncle said that if you subtract 15 from 3 times his age you would get 60. Be a wrote this equation: 3x- 15= 60. how old is Bea's uncle? PLZ I NEED THIS ANSWER RIGHT AWAY ITSFOR A TEST AND I NEED HELPPPP
Answer: Bea's uncle is 25 years old.
Step-by-step explanation:
Given the equation [tex]3x- 15= 60[/tex], we can say that the variable "x" represents the age of Bea's uncle. Then to find his age, we need to solve for "x":
We must add 15 to both sides of the equation:
[tex]3x- 15+(15)= 60+(15)\\3x=75[/tex]
Now we need to divide both sides of the equation by 3:
[tex]\frac{3x}{3}=\frac{75}{3}\\\\x=25[/tex]
Therefore, we can conclude that Bea's uncle is 25 years old.

What is the point-slope form of a line with slope -5 that contains the point
(2,-1)?
O A. y-1 = 5(x+2)
O B. y+1 =-5(x-2)
O C. y+ 1 = 5(x + 2)
O D. y-1 = -5(x-2)
Answer:
y + 1 - 5(x - 2)
Step-by-step explanation:
Borrow (2, -1): Substitute 2 for x and -1 for y, and -5 for m in y = mx + b:
-1 = -5(2) + b. Then b = 9, and the desired equation in point-slope form is:
y - (-1) = -5(x - 2), or
y + 1 - 5(x - 2)
The point-slope form of a line with slope -5 that contains the point
(2,-1) is y+1=-5(x-2). Therefore, option B is the correct answer.
What is the point slope form?The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.
The equation of the point slope form is: (y - y₁) = m(x - x₁)
where, (x, y) is a random point on the line and m is the slope of the line.
Given that, a line with slope -5 that contains the point (2, -1).
Substitute m=-5 and (x₁, y₁)=(2, -1) in the point slope form, we get
(y-(-1))=-5(x-2)
y+1=-5(x-2)
y+1=-5x+10
5x+y-9=0
Therefore, option B is the correct answer.

-0.75-(-2/5)+0.4+(-3/4)
-0.75-(-2/5)+0.4+(-3/4) = -0.7 simplified, how I got this answer can be found below in 16 steps.
1 - First thing we want to do is remove the parentheses.
-0.75 - (-2/5) + 0.4 - 3/4
2 - Then we simplify, multiply -1 by -1.
-0.75 + 1 (2/5) + 0.4 - 3/4
3 - Then multiply 2/5 by 1.
-0.75 + 2/5 + 0.4 - 3/4
4 - Then we want to write - 0.75/1 as a fraction with a common denominator, we do this by multiplying by 5/5.
-0.75/1 * 5/5 + 2/5 + 0.4 - 3/4
5 - Then we write each expression with a common denominator of 5, we multiply each one by a factor of one.
-0.75 * 5/1*5 + 2/5 + 0.4 - 3/4
6 - Then we multiply 5 by 1.
-0.75 * 5 / 5 + 2/5 + 0.4 - 3/4
7 - Then we combine the numerators over the common denominator.
-0.75*5+2/5+0.4-3/4
8 - We multiply -0.75 by 5.
-3.75 + 2/5 + 0.4 - 3/4
9 - Then we add -3.75 and 2.
-1.75/5+0.4-3/4
10 - And then we divide -1.75 by 5.
-0.35 + 0.4 - 3/4
11 - Then add -0.35 and 0.4.
0.05 - 3/4
12 - We then write 0.05/1 as a fraction with a common denominator, we do this via multiplying it by 4/4.
0.05/1 * 4/4 - 3/4
13 - Then we write each expression with a common denominator of 4, through multiplying each by a factor of 1.
0.05 * 4/4 - 3/4
14 - We combine the numerators over the common denominator.
0.05 * 4 - 3 / 4
15 - We simplify.
-2.8 / 4
16 - Then we divide -2.8 / 4
The final answer is -0.7

A bag contains 2 red marbles and 4 green marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then a second marble is drawn. What is the probability that the first marble is green and the second one is red?
Answer:
Step-by-step explanation:
Red = 2
Green = 4
P(G) = 4/6
P(R) = 2/5 (remember that 1 green marble is green. The total left is 5 so the 5 is not a typo)
P(G then R) = 4/6 * 2/5
P(G then R) = 2/3 * 2/5
P(G then R) = 4/15

Explain Step-by-step please
I need the work
Answer:
The base is [tex]11\ in[/tex] and the height is [tex]14\ in[/tex]
Step-by-step explanation:
we know that
The area of the triangle is equal to

Circle Y has a center at (2,3) and a radius of 4. Circle Z has a center at (2,−3) and a radius of 10. What is the scale factor of all radii of circle Y to all radii of circle Z?
Final answer:
The scale factor of all radii of circle Y to all radii of circle Z is 0.4.
Explanation:
To find the scale factor of all radii of circle Y to all radii of circle Z, we can compare their radii.
Circle Y:
Center: (2,3)
Radius: 4
Circle Z:
Center: (2,-3)
Radius: 10
The scale factor is determined by comparing the radii of the two circles. The radius of circle Y is 4 and the radius of circle Z is 10. To find the scale factor, we divide the radius of circle Y by the radius of circle Z: 4/10 = 0.4.
Therefore, the scale factor of all radii of circle Y to all radii of circle Z is 0.4.

The square root of a number is 6. What is the other square root of this number?
Answer:
-6
Step-by-step explanation:
If the square root of a number is 6, then the number must be 36 (6*6=36)
However, negatives*negatives also equal positives, so
-6*-6 also =36
hence, your answer should be -6
Final answer:
The other square root of a number whose one square root is 6 is -6, because both 6 and -6 squared give the positive number 36.
Explanation:
The question you're asking pertains to finding square roots of a number. Given that one square root of a number is 6, the other square root would also be 6, but with an opposite sign, so it's -6. This is because when either 6 or -6 is squared (multiplied by itself), the result is 36. So, the number you're looking for is 36, and it has two square roots: 6 and -6. This is because the equation x² = √x holds true for both positive and negative values of x that yield the same positive result when squared.
To find the other square root of the number, we need to consider the fact that a positive number has two square roots - one positive and one negative.
Since the given square root is positive and equal to 6, the other square root would be its negative counterpart, which is -6.
