Non Shaded = 6 × 6
= 36
Now Ratio of shaded portion is 64:100
= 16:25
Percentage = 64/100 × 100

I will give Brian list plz help
Answers
Answer:
The Answer is 0.03
Step-by-step explanation:
Andrea = 3.12/8 flower per cupcake
3.12/ 8 = .39
Corey = 2.25/ 7 flower per cupcake

A jar contains 734 L of milk. After packing the milk in 20 packets of equal capacity, 14 L of milk was still left in the jar. What is the quantity of milk in each of the smaller packets?
Answers
Answer:
[tex]36\text{ liters}[/tex]
Step-by-step explanation:
After the 20 packets of milk were packed from the 734 L of milk in the jar, 14 L of milk were still lift. Therefore, [tex]734-14=720[/tex] liters of milk were used to pack the 20 packets.

Please help! Answers with explanations will be marked brainliest!
Answers
Answer: Well if you were going to think of a circle you can divide it into 4 equal sizes in one of the is equal to two pentagons and a half. If you add all is equal to a loop full of pentagons [which makes 10 pentagons]. Because the ring is made out of regular pentagons, we can work out that each of the interior angles of each pentagon is 108* degrees. By extending the lines that two pentagons share, assuming they will all meet in the middle, it will create a triangle. As we know each angle of a [regular] pentagon is 108* degrees, we know the two base angles of the triangle would equal to 72** which leaves the top angle to be 36 degrees. As [the sum of] angles at a point is 360 degrees, and 36 is divisible by 360, it will make a complete ring. Also, as 360 ÷ 36 = 10, we know that the ring will be made out of 10 pentagons. as formula to calculate the the size of a interior angle of a polygon is (n×180−360)÷n (for n being the number of sides that the polygon has). because the triangle is made by extending the lines, and angles on a line is 180 degrees, 180−108 (an interior angle of a pentagon) =72.

White kernels = 800 * 0.2 = 160
Yellow kernels = 800 * 0.8 = 640
b:
1 ear weight = 0.25 pounds
12 ears weight = 12 * 0.25 = 3 pounds
a. The number of kernels which are yellow is 640.
b. The amount of kernels will be 3 pounds.
An expression is a combination of symbols, variables, numbers, and operators that represents a value or a computation. It can consist of constants, variables, and mathematical operations such as addition, subtraction, multiplication, division, exponentiation, and more.
Expressions can be simple or complex, involving multiple terms and operations. They are commonly used in mathematics, computer programming, and symbolic logic to represent calculations, equations, and relationships between quantities.

Find an equation of the line: through the point (2,-4) with a y-intercept oof -2
Answer quick please !!!!!
Answers
Answer:
y = -x-2
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = mx-2
Using the point (2, -4)
-4= m(2) -2
Add 2 to each side
-4+2 = 2m-2+2
-2 =2m
Divide by 2
-2/2 = 2m/2
-1 =m
y = -1x -2
y = -x-2
Answer:
y=-x-2
Step-by-step explanation:
Since we know two points on the graph (2,-4) and (0,-2) we can find the slope because slope= change in y over change in x. By doing so, we can see that the slope is -1. We know that y=mx+b and m is slope and b is y-intercept so we have all the variables needed. y=-1x-2 or y=-x-2.
what is the gradient?
Answers
Answer:
[tex]{ \tt{gradient = \frac{ - 3 - 1}{0 - ( - 1)} }} \\ = \frac{ - 4}{1} \\ = - 4[/tex]
Answer:
The gradient (slope) is -4.
Step-by-step explanation:
Note that two points on the graph through which the blue line passes exactly are (-2, 5) and (0, -3). As we move from the first point to the second, x increases by 2 (the 'run') and y (the 'rise') decreases by 8. Thus, the gradient, or slope, of this line is m = rise/run = -8/2, or m = -4.

MacKenzie surveys 80 of her classmates and finds that 65% of them like sports. She also finds that 75% of her 64 relatives like sports. How many more of her classmates like sports as compared to her relatives? Pls help
Answers
Answer:
65%×80=52
(80-52=28) no of classmates who liked sports
75%×64=48
(64-48=16) no of relatives who liked sports
no of classmates who liked sports - no of relatives who liked sports
= 28-16 = 12
Hence, 12 more of her classmates like sports as compared to her relatives
There are total 4 more of her classmates like sports as compared to her relatives.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the information given in the question,
Total number of students surveyed = 80
Percentage of students who like sports = 75%
So,
(80 × 65)/100
= 5200/100 = 52
Total number of Relatives = 64
Percentage of relatives who like sports = 75%
So,
(64 × 75)/100
= 4800/100 = 48
Then, the number more of her classmates like sports compared to relatives will be:
52 - 48
= 4
