300 stone tiles would be needed to make a patio that has a total area of 300 ft²
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Area of triangle = (1/2) * base * height = 0.5 * 20 ft * 6 ft = 60 ft²
Area of rectangle = base * height = 20 ft * 12 ft = 240 ft²
Total area of patio = 60 ft² + 240 ft² = 300 ft²
Number of stone tiles needed = 300 ft² / 1 ft² = 300
300 stone tiles would be needed to make a patio that has a total area of 300 ft²

a basket contains red, green, yellow apples. An apple is selected at random if p(red) is 2/5 P(yellow) is 1/4 what is p(green)?
A. 3/20
B. 7/20
C. 1/10
D. 13/20
The probability of getting the green apple is 7/20 option (B) 7/20 is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
P(red) = 2/5
P(yellow) = 1/4
The sum of the probability of the event is 1.
P(red) + P(yellow) + P(green) = 1
2/5 + 1/4 + P(green) = 1
P(green) = 1 - (2/5 + 1/4)
P(green) = 7/20
Thus, the probability of getting the green apple is 7/20 option (B) 7/20 is correct.

B. 43.3 ft
•
C. 14.4 ft

D. 17.7 ft
Given
[tex] \text{Length of the tree= 25 feet} \\ \text{Angle of Elevation= 30°}[/tex]
To Find[tex] \text{Height Of The Tree}[/tex]
[tex] \text{Let The Height of the Tree be ‘x’}[/tex]
We Know:-

A cube is numbered 1 through 6. If the cube is rolled twice, how many of the possible outcomes will have two even numbers? 3 9 18 36
======================================================
Explanation:
3/6 = 1/2 of the numbers on the cube are even (2,4,6)
If we wanted both cubes to show an even number, then this comes up (1/2)*(1/2) = 1/4 of the time.
There are 6*6 = 36 outcomes total, so there are (1/4)*36 = 9 outcomes when both dice show an even number.
---------
Those nine outcomes are listed below
A = 2, B = 2A = 2, B = 4A = 2, B = 6A = 4, B = 2A = 4, B = 4A = 4, B = 6A = 6, B = 2A = 6, B = 4A = 6, B = 6You probably have noticed that A has 3 choices (2,4,6) and so does B. That gives 3*3 = 9 outcomes total. This is an alternative pathway compared to the previous section.

I can't give the exact answer as the base pay and weekly hours arn't stated but here's how to solve letters in parentheses are place holders just plug in the numbers accordingly :)
Step-by-step explanation:
A.
figures needed, base pay (p) total hours worked (t) half
Saturday
p÷2= the ½ in time and a half (x)
p+x= 1 hr Saturday pay (s)
s+2= r (to cover the 30m)
7:00am to 11:30am 4hr 30m
12:00pm to 4:00pm 4hr
add them
8hr 30m
(s×8)+r= how much you were paid on Saturday
Sunday
p×2= h dubble pay
Calculate how many hrs worked on Sunday and apply the same logic as for Saturday appropriately divide the time if it doesn't come out as an even hour.
Final
Add Saturday and Sunday pay together to get weekend pay.
B.
Same formula hours worked times hourly pay.
Add the weekday and weekend pay together and thats pt B.

this cylindrical fish tank has a height of 38 inches and diameter of 26 inches. what is the volume of the fish tank.
Answer:
using π as 3.14: 20165.08 cubic inches
in terms of π: 6422π cubic inches
Step-by-step explanation:
» Concepts
The volume of a cylinder is how much space the cylinder can take inside of it. The formula to find this volume is πr²h, where r = radius and h = height. In addition, it's important to know that the radius is half the diameter.
» Application
We're given the radius as 13 inches (26/2 = 13), and the height is 38 inches. Now, we just have to plug in the values and simplify.
» Solution
Using π as 3.14:

What is the midline of the function graphed below?
y = 1
y= 0.5
y = 0
y =2
The midline of the given graphed function for the y-coordinate is equal to y = 0.
The midline of a set of functions, you need to determine the average of their highest and lowest points.
For the functions represented in the graph,
y = 0.5.
The highest point is 0.5 for the graph.
y = -0.5
The lowest point is-0.5.
The midline of the set of functions is the average of their highest and lowest points.
Midline represented by a horizontal line.
Midline is the line that exactly passes through the midpoint of the highest and the lowest point.
Here on y-axis we have ,
Highest coordinate = 0.5
Lowest coordinate = -0.5
Midline point = ( highest point + lowest point ) / 2
Substitute the value we get,
⇒midline point = ( 0.5 + (-0.5))/ 2
⇒midline point = 0 /2
⇒midline point = 0
Therefore, the midline of the function of the graph is y = 0.

A biased coin is flipped twice.
The probability of the coin landing on tailsis 0.4. Find the probability the coin lands on tails exactly once.
Answer:
0.48.
Step-by-step explanation:
There are 2 ways that a tail lands once:-
Tail + head or
head + tail.
Prob(Tail on one throw) = 0.4
Prob(Head on one throw) = 1 - 0.4 = 0.6.
Prob(Tail first then head) = 0.4 * 0.6 = 0.24
Head then tail has the same probability (0.6*0.4).
So the requred probability = 0.24 + 0.24
= 0.48.
